Risks Relating to Our Financial Position and Our Business

We have a history of operating losses and cannot give assurance of future revenues or operating profits; investors may lose their entire investment.

We do not expect to generate revenue or profitability that is necessary to finance our operations in the short term. We incurred net losses of $17,424,237 and $17,081,617 for the years ended December 31, 2021 and 2020, respectively. In addition, our accumulated deficit as of December 31, 2021 and 2020 was $199,705,048 and $182,280,811, respectively. Losses have principally resulted from costs incurred for manufacturing, clinical trial and preclinical activities and general and administrative expenses. We have funded our operations primarily through the private placement and public offering of equity securities. As of December 31, 2021, we had cash of $9,361,270.

To date, we have not commercialized any products or generated any revenues from the sale of products, and absent the realization of sufficient revenues from product sales, we may never attain profitability in the future. We expect to incur significant losses for the foreseeable future as we continue to conduct research and development, clinical testing, regulatory compliance activities and, if nomacopan or other future product candidates receive marketing authorization, sales and marketing activities.

Our failure to become and remain profitable could depress the market price of the ADSs and could impair our ability to raise capital, expand our business, diversify our product offerings or continue our operations. If we continue to suffer losses as we have in the past, investors may not receive any return on their investment and may lose their entire investment.

Our auditor’s report on our financial statements states that our recurring operating losses, negative cash flows and dependence on additional financial support raises substantial doubt about our ability to continue as a going concern, which may have a detrimental effect on our ability to obtain additional funding.

The report of our U.S. independent registered public accounting firm on our financial statements for the period ended December 31, 2021, includes an explanatory paragraph raising substantial doubt about our ability to continue as a going concern as a result of our recurring losses from operations and net capital deficiency. Our future is dependent upon our ability to obtain financing in the future. This opinion could materially limit our ability to raise funds. If we fail to raise sufficient capital when needed, we will not be able to complete our business plan. As a result, we may have to liquidate our business and investors may lose their investment in our ADSs.

We will require additional capital to fund our operations, and if we are unable to obtain such capital, we will be unable to successfully develop and commercialize any product candidates.

As of December 31, 2021, we had cash of approximately $9,361,270.  In June 2020, we entered into a securities purchase agreement, or Purchase Agreement, with Aspire Capital Fund, LLC, or Aspire Capital which provides that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital is committed to purchase up to an aggregate of $30.0 million of our ADSs. Pursuant to the Purchase Agreement, Aspire Capital has purchased 5,784,059 of our ADSs through April 30, 2022 for gross proceeds of approximately $8.0 million. See “Item 5B. Operating and Financial Review and Prospects — Liquidity and Capital Resources — Aspire Capital Financing Arrangement”. We will require additional capital in order to develop and commercialize our current product candidates or any product candidates that we acquire, if any. There is no assurance that additional funds will be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available on a timely basis, we may be required to terminate or delay development for one or more of our product candidates.

The extent to which we utilize the Purchase Agreement with Aspire Capital as a source of funding will depend on a number of factors, including the prevailing market price of our ADSs, the volume of trading in our ADSs and the extent to which we are able to secure funds from other sources. The number of ADSs that we may sell to Aspire Capital under the Purchase Agreement on any given day and during the term of the agreement is limited. Additionally, we and Aspire Capital may not effect any sales of ADSs under the Purchase Agreement during the continuance of an event of default or on any trading day that the closing sale price of our ADSs is less than $0.25 per share.

Table of Contents

The amount and timing of any expenditure needed will depend on numerous factors, some of which are outside our control, including:

We have not sold any products, and we do not expect to sell or derive revenue from any product sales for the foreseeable future. We may seek additional funding through future debt and equity financing, as well as potential additional collaborations or strategic partnerships with other companies or through non-dilutive financings. Additional funding may not be available to us on acceptable terms or at all. General market conditions may make it difficult for us to seek financing from the capital markets and the COVID-19 outbreak could impact the availability or cost of future financings. We may be required to relinquish rights to our technologies or product candidates, or grant licenses on terms that are not favorable to us, in order to raise additional funds through alliance, joint venture or licensing arrangements. In addition, the terms of any financing may adversely affect the holdings or the rights of our shareholders and the issuance of additional shares by us, or the possibility of such issuance, may cause the market price of our shares to decline.

If we are unable to obtain funding on a timely basis, we will be delayed or unable to complete ongoing and planned clinical trials for nomacopan and we may be required to significantly curtail some or all of our activities. We also could be required to seek funds through arrangements with collaborative partners or otherwise that may require us to relinquish rights to our product candidates or some of our technologies or otherwise agree to terms unfavorable to us.

Future sales and issuances of the ADSs or rights to purchase ADSs and any equity financing that we pursue, could result in significant dilution of the percentage ownership of our shareholders and could cause our ADS price to fall.

We may seek additional capital through a combination of private and public equity offerings, debt financings, strategic partnerships or licensing arrangements. In any financing transaction, we may sell ordinary shares or ADSs, convertible securities or other equity securities. To the extent that we raised additional funds by issuing equity securities (including up to an additional $22 million of ADSs to Aspire Capital Fund, LLC, or Aspire Capital, as of April 30, 2022 pursuant to our financing arrangement with Aspire Capital), our shareholders may experience significant dilution. See “Item 5B. Operating and Financial Review and Prospects — Liquidity and Capital Resources — Aspire Capital Financing Arrangement”. To the extent that we raise additional capital through sales of ADSs to Aspire Capital, or the sale of equity or convertible debt securities by any other means, existing ownership interests will be diluted. The sale of a substantial number of ADSs by Aspire Capital, or anticipation of such sales, could cause the trading price of our ADSs to decline or make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise desire. However, we have the right to control the timing and amount of sales of ADSs to Aspire Capital, and we may terminate the financing arrangement at any time, at our discretion, without any penalty or cost to us.

Risks Related to the Clinical Development and Marketing Authorization of Our Product Candidates

Our business depends on the success of nomacopan, which is still under development. If we are unable to obtain marketing authorization for or successfully commercialize nomacopan, our business will be materially harmed.

Nomacopan has been the primary focus of our product development. Successful continued development and ultimate marketing authorization of nomacopan for at least one indication is critical to the future success of our business. We have invested, and will continue to invest, a significant portion of our time and financial resources in the development of nomacopan. We will need to raise sufficient funds for, and successfully enroll and complete, our ongoing clinical development programs for nomacopan and for our planned clinical development programs for nomacopan in other indications. The future regulatory and commercial success of this product candidate is subject to a number of risks, including the following:

Of the large number of drugs in development in the pharmaceutical industry, only a small percentage results in the submission of a biologics license application, or BLA, to the FDA, or a marketing authorization application, or MAA, to the EMA and even fewer are approved for commercialization. Furthermore, even if we do receive marketing authorization to market nomacopan, any such approval may be subject to limitations on the indicated uses or patient populations for which we may market the product. Accordingly, even if we are able to obtain the requisite financing to continue to fund our development programs, we cannot assure that nomacopan will be successfully developed or commercialized. If we or any of our future development partners are unable to develop, or obtain marketing authorization for, or, if approved, successfully commercialize nomacopan, we may not be able to achieve forecasted revenues.

Table of Contents

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

We may not be able to initiate or continue clinical trials required by the FDA, MHRA, EMA or other foreign regulatory agencies for nomacopan if we are unable to locate and enroll a sufficient number of eligible patients to participate in these clinical trials. We will be required to identify and enroll a sufficient number of patients with BP, HSCT-TMA and other diseases for each of our ongoing and planned clinical trials of nomacopan in these indications. To date, we have experienced delays in enrollment of patients in our clinical trials and supply chain issues due in particular to the COVID-19 pandemic and, in the case of enrollment delays, the fact that we are targeting a small patient population with a rare disease or indication. In May 2022, we received a final report regarding the delays in patient recruitment in BP due to supply chain issues with a third party supplier. As of the date of this Annual Report on Form 20-F, we have resolved such issues, and we do not anticipate further delays at this time.

Patient enrollment is affected by other factors, including:

Our inability to enroll a sufficient number of patients for any of our clinical trials would result in significant delays or may require us to abandon one or more clinical trials.

11

Table of Contents

If clinical trials or marketing authorization processes for nomacopan are prolonged, delayed or suspended, we may be unable to commercialize nomacopan on a timely basis.

We cannot predict whether we will encounter problems with any of our completed, ongoing or planned clinical trials that will cause us, or any regulatory authority, to delay or suspend those clinical trials and may negatively impact our ability to obtain marketing authorization for, and to market and sell, a particular product candidate, including:

Commercialization may be delayed by the imposition of additional conditions on our clinical trials by the FDA, MHRA, EMA or any other applicable foreign regulatory authority or the requirement of additional supportive studies by the FDA, MHRA, EMA or such foreign regulatory authority.

Public health epidemics or outbreaks could adversely impact our business. The situation surrounding the COVID-19 pandemic, including the mutation of variants, continues to remain fluid globally and we continue to manage ongoing challenges associated with the pandemic as they relate to operations. The potential for a material impact on our business, financial condition and results of operation remains a risk. We cannot reasonably estimate with any degree of certainty any future impact of COVID-19. Pandemics such as this can adversely impact our business as a result of disruptions, such as travel bans, quarantines, staffing shortages, and interruptions to access the trial sites and supply chains, which could result in material delays and complications with respect to our research and development programs and clinical trials.

Moreover, as a result of COVID-19, there is a general unease of conducting certain non-critical activities in medical centers. For example, while now open for enrollment, prior clinical trials have been halted or delayed due to COVID-19. Delays in our clinical trials will result in increased development costs for our product candidates, and our financial resources may be insufficient to fund any incremental costs. In addition, if our clinical trials are delayed, our competitors may be able to bring products to market before we do and the commercial viability of our product candidates could be limited. The extent to which COVID-19 impacts operations will depend on future developments, including the scope of any new virus mutations and outbreaks, the nature of government public health guidelines and the public’s adherence to those guidelines, the rate of individuals becoming fully vaccinated and the public’s adherence to guidelines to receive booster vaccinations, and the extent to which new lockdowns may be needed or are required in particular countries, including China. In particular, the continued spread of COVID-19 globally could adversely impact our operations and workforce, including research and clinical trials and the ability to raise capital, could affect the operations of key governmental agencies, such as the FDA, which may delay the development of our product candidates, and could result in the inability of suppliers to deliver components or raw materials, including drug product and drug substance, on a timely basis or at all, each of which in turn could have an adverse impact on our business, financial condition and results of operation.

The efficacy of nomacopan may not be known until advanced stages of testing, after we have incurred significant product development costs which may not be recoverable.

Nomacopan may fail to show the desired safety and efficacy at any phase in the clinical development programs. Good efficacy in animal models of the target indication are no guarantee of success in human clinical trials. Often there is no adequate animal model of a human disease, such as PNH. As a result, the first definitive proof of efficacy may not occur until clinical trials in humans. In our Phase II PNH trial, while we determined that overall the trial met the primary endpoint, individually two of the seven patients who completed the trial did not meet the primary endpoint (which was assessed at day 28) and an additional patient who withdrew from the trial on day 43 did not meet the primary endpoint. If nomacopan does not demonstrate adequate efficacy, its development may be delayed or terminated, which could have a material adverse effect on our financial condition and results of operation.

12

Table of Contents

Results of earlier preclinical studies or clinical trials may not be predictive of advancement to the next phase of development.

Completion of preclinical studies or clinical trials does not guarantee that we will initiate additional studies or trials for our product candidates. If further studies or trials are initiated, earlier preclinical studies or clinical trials may not predict the scope and phase of further trials, that these further studies or trials will be completed, or that if these further studies or trials are completed, that the design or results will provide a sufficient basis to apply for or receive marketing authorizations or to commercialize products. Results of clinical trials could be inconclusive, requiring additional or repeat trials. Data obtained from preclinical studies and clinical trials is subject to varying interpretations that could delay, limit or prevent marketing authorization. If the results achieved in our clinical trials are insufficient to proceed to further trials or to marketing authorization of our product candidates, we could be materially adversely affected. Failure of a clinical trial to achieve its pre-specified primary endpoint generally may require us to undertake additional studies or trials if we determine to continue development of the product candidate, may reduce the timely development of and marketing authorization to market the product candidate, and may decrease the chances for successfully achieving the primary endpoint in scientifically similar indications.

The route of administration or dose for nomacopan may be inadequate to obtain marketing authorization or successfully commercialize.

Inadequate drug availability as a result of the route of administration or the target tissue availability of the drug is another potential cause of lack of efficacy of nomacopan, if and when it is commercialized. Complement component C5, the target of nomacopan, is predominantly found in blood. For BP and HSCT-TMA, nomacopan is being administered subcutaneously, which could delay commercialization of nomacopan and result in significant additional costs to us.

Long-term animal toxicity and long-term human safety studies of nomacopan could demonstrate that the administration of nomacopan results in serious adverse events.

While we have conducted toxicity studies in certain animals with no observed adverse effect at the highest dose tested, we intend to conduct further long-term animal toxicity studies, including reproductive and carcinogenicity studies, and are currently conducting a long-term human safety study of nomacopan. Such studies may show that nomacopan results in serious adverse events or other adverse results. If animal toxicity and human safety studies do not yield favorable results, we may be required to abandon our development of nomacopan, which could have a material adverse effect on our financial condition, including our ability to generate forecasted revenues.

Chronic dosing of patients with nomacopan could lead to an immune response that causes adverse reactions or impairs the activity of the drug.

There is a risk that chronic dosing of patients with nomacopan may lead to an immune response that causes adverse reactions or impairs the activity of the drug. Patients may develop an allergic reaction to the drug and/or develop antibodies directed at the drug. Impaired drug activity could be caused by neutralization of the drug’s inhibitory activity or by an increased rate of clearance of the drug from circulation.

One potential side effect of nomacopan that has occurred in patients receiving currently marketed C5 inhibitors and C3 inhibitors is an increased incidence of meningitis. As a result, we expect that patients receiving nomacopan would also receive meningitis immunization and prophylactic antibiotics as indicated.

Nomacopan has a secondary binding site that sequesters leukotriene B4, or LTB4. LTB4 synthesis from arachidonic acid can be induced by a variety of triggers including terminal complement activation. LTB4 is a pro-inflammatory mediator that attracts and activates white blood cells at the area of inflammation. LTB4 inhibition may lead to positive anti-inflammatory benefits, but like other drugs with immune modulating properties may increase the risk of infection. However, a particular risk of infection associated with inhibition of LTB4 has not been identified and the only marketed drug which inhibits leukotrienes including LTB4, does not carry a warning of elevated infection risk on its label.

Any immune response that causes adverse reactions or impairs the activity of the drug could cause a delay in or termination of our development of nomacopan, which would have a material adverse effect on our financial condition and results of operation.

13

Table of Contents

If nomacopan is not convenient for patients to use, then we might be prevented from successful commercialization.

Nomacopan may require cold storage prior to use and will likely require self-injection for certain indications. If the drug product is not stable at temperatures of between four and eight degrees Celsius, then the drug product may need to be defrosted before use, which patients could view as inconvenient, causing sales to not achieve forecasts. In addition, if nomacopan shows a lack of long-term stability at low storage temperatures, this may negatively impact our ability to manage the commercial supply chain, which could result in us having to refund customers or replace products that are unstable, which could materially increase our costs and have a material adverse effect on our financial condition and results of operation.

Because nomacopan has not yet received marketing authorization, it is difficult to predict the time and cost of development and our ability to successfully complete clinical development and obtain the necessary marketing authorizations for commercialization.

Nomacopan has not yet received marketing authorization for the treatment of any indications, and unexpected problems may arise that could cause us to delay, suspend or terminate our development efforts.  To date, only a limited number of patients have been enrolled in our clinical trials. Larger scale trials will be required to obtain marketing authorization and the efficacy or non-efficacy of nomacopan will ultimately be determined by the applicable regulatory agencies. The long-term safety consequences of inhibition of C5 and/or LTB4 with nomacopan is not known. Marketing authorization of product candidates such as nomacopan can be more expensive and take longer than approval with previously approved products.

We have obtained orphan drug designation for nomacopan in the United States for the use in BP and HSCT-TMA, and in the EU for GBS, PNH, and BP, but we may be unable to maintain the benefits associated with orphan drug designation, including market exclusivity.

In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Although we have received orphan drug designation for nomacopan in GBS, HSCT-TMA, PNH and BP and intend to seek orphan product designation for nomacopan in further indications, we may never receive such additional designations and we are not currently pursuing a clinical development program targeting GBS or PNH.

If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a biologics license application, or BLA, to market the same biologic for the same indication for seven years, except in limited circumstances such as a showing of clinical superiority to the product with orphan product exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Even if we were to obtain orphan drug designation for nomacopan for a particular indication, we may not be the first to obtain marketing approval for any particular orphan indication due to the uncertainties associated with developing biological products. If we do obtain exclusive marketing rights in the United States, they may be limited if we seek approval for an indication broader than the orphan designated indication, and may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of the relevant patients. Further, exclusivity may not effectively protect the product from competition because different drugs with different active moieties can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve a drug with the same active moiety for the same condition if the FDA concludes that the later drug is safer, more effective, or makes a major contribution to patient care.

In the EU, where a marketing authorization in respect of an orphan medicinal product is granted, the Agency and the Member States shall not, for a period of 10 years, accept another application for a marketing authorization, or grant a marketing authorization or accept an application to extend an existing marketing authorization, for the same therapeutic indication, in respect of a similar medicinal product. A marketing authorization may be granted, for the same therapeutic indication, to a similar medicinal product if: (i) the holder of the marketing authorization for the original orphan medicinal product has given his consent to the second applicant; (ii) the holder of the marketing authorization for the original orphan medicinal product is unable to supply sufficient quantities of the medicinal product; or (iii) the second applicant can establish in the application that the second medicinal product, although similar to the orphan medicinal product already authorized, is safer, more effective or otherwise clinically superior.

Table of Contents

The receipt of orphan drug designation status does not change the regulatory requirements or process for obtaining marketing approval and orphan drug designation does not mean that marketing approval will be granted.

We have obtained fast track designation from the FDA for the treatment of HSCT-TMA and BP, and may seek such designation in other indications. Such designation or a similar designation from other national or international regulatory agencies, may not lead to a faster development or regulatory review or approval process, and may not result in nomacopan or any other product candidates receiving marketing approval.

In addition to the fast track designation we have received for HSCT-TMA and BP, we may seek a breakthrough therapy or fast track designation for nomacopan in other indications. A breakthrough therapy is defined as a product that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints. Designation as a breakthrough therapy is within the discretion of the FDA. Receipt of a breakthrough therapy designation for nomacopan may not result in a faster development process, review or approval compared to products considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if nomacopan qualifies as a breakthrough therapy, the FDA may later decide that it no longer meets the conditions for qualification.

Even if we obtain FDA approval of nomacopan, we or our partners may never obtain approval or commercialize our product candidates outside of the United States and, conversely, even if we obtain marketing authorization of nomacopan in the EU, we or our partners may never obtain approval or commercialize our product candidates outside the EU.

In order to market any products in a country, we must establish and comply with numerous and varying regulatory requirements regarding clinical trial design, safety and efficacy. Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and marketing authorization in one country does not mean that marketing authorization will be obtained in any other country. Approval procedures vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking marketing authorizations in other countries could result in significant delays, difficulties and costs for us, and may require additional preclinical studies or clinical trials, which could be costly and time consuming and could delay or prevent introduction of nomacopan in those countries. We rely on contract research organizations to run our clinical trials and on regulatory consultants for experience in obtaining marketing authorization in international markets. If we or our partners fail to comply with regulatory requirements or to obtain and maintain required approvals, our target market may be reduced and our ability to realize the forecasted revenues of nomacopan may be harmed.

If we or our partners market products in a manner that violates fraud and abuse and other healthcare laws, or if we or they violate government price reporting laws, we or our partners may be subject to administrative civil and/or criminal penalties.

In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal healthcare laws, including those commonly referred to as “fraud and abuse” laws have been applied in recent years to restrict certain marketing practices in the pharmaceutical industry. These laws include, among others, false claims and anti-kickback statutes. At such time, if ever, as we or any of our partners market any of our future approved products, it is possible that some of the business activities of us and/or our partners could be subject to challenge under one or more of these laws.

Federal false claims, false statements and civil monetary penalties laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or to get a false claim paid. The federal healthcare program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce, or in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or other federally financed healthcare programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers and formulary managers on the other. Although there are several statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution, they are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not qualify for an exception or safe harbor.

In addition, we and/or our partners may be subject to data privacy and security regulation, including the Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their respective implementing regulations, which impose specified requirements relating to the privacy, security and transmission of individually identifiable health information.

Most states also have statutes or regulations similar to these federal laws, which may apply to items such as pharmaceutical products and services reimbursed by private insurers. We and/or our partners may be subject to administrative, civil and criminal sanctions for violations of any of these federal and state laws.

Our employees, principal investigators, consultants, commercial partners or vendors may engage in misconduct or other improper activities, including non-compliance with regulatory standards.

We are also exposed to the risk of employees, independent contractors, principal investigators, consultants, commercial partners or vendors engaging in fraud or other misconduct. Misconduct by employees, independent contractors, principal investigators, consultants, commercial partners and vendors could include intentional failures to comply with United Kingdom, or U.K., European Union, or EU, regulations, to provide accurate information to the UK, EMA or EU Member States authorities or to comply with manufacturing or quality standards we have or will have established. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices such as promotion of products by medical practitioners. Of general application are the European Anti-Fraud Office Regulation 883/2013, and the UK Bribery Act 2010. Under the latter, a commercial organization can be guilty of the offence if the bribery is carried out by an employee, agent, subsidiary, or another third-party, and the location of the third-party is irrelevant to the prosecution. The advertising of medicinal products in the EU is regulated by Title VIII of European Directive 2001/83/EC. The corresponding UK legislation is Part 14 of the Human Medicines Regulations 2012 (S.I. 2012/1916 as amended). Such laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Misconduct could also involve the improper use of information obtained in the course of clinical studies, which could result in regulatory sanctions and serious and irreparable harm to our reputation.

This could also apply with respect to data privacy. In the EU, the General Data Protection Regulation (EU) 2016/679, or GDPR, lays down the legal framework for data protection and privacy. The GDPR applies directly in EU Member States and applies to companies with an establishment in the EEA and to certain other companies not in the EEA that offer or provide goods or services to individuals located in the EEA or monitor the behavior of individuals located in the EEA. Since January 1, 2021, the UK is not part of the EU. In the UK, the GDPR has been converted into UK domestic law, pursuant to the Data Protection, Privacy and Electronic Communications (Amendments etc) (EU Exit) Regulations 2019 (as amended), which makes some minor technical amendments to ensure the GDPR is operable in the UK (UK GDPR). The UK GDPR is also supplemented by the Data Protection Act 2018. UK and EU data protection law is therefore aligned. The GDPR and UK GDPR implement stringent operational requirements for controllers of personal data, including, for example, expanded disclosures about how personal information is to be used, limitations on retention of information, increased requirements pertaining to health data and pseudonymized (i.e., key-coded) data, increased cyber security requirements, mandatory data breach notification requirements and higher standards for controllers to demonstrate that they have obtained a valid legal basis for certain data processing activities. The activities of data processors are being regulated for the first time, and require companies undertaking processing activities to offer certain guarantees in relation to the security of such processing and the handling of personal data. Contracts with data processors will also need to be updated to include certain terms prescribed by the GDPR, and negotiating such updates may not be fully successful in all cases. The GDPR provides that EU Member States may make their own further laws and regulations in relation to the processing of genetic, biometric or health data, which could result in differences between Member States, limit our ability to use and share personal data or could cause our costs to increase, and harm our business and financial condition. We are also subject to evolving and strict rules on the transfer of personal data out of the EU and UK to the United States, under both the GDPR and the UK GDPR. Under the GDPR personal data cannot be transferred to a third country (i.e. outside of the EEA or UK, as applicable) unless certain safeguards are in place. These include, for example, where the transfer is to a country that the EU Commission has deemed “adequate” or where EU standard contractual clauses have been implemented. Further prospective revision of the Directive on privacy and electronic communications (Directive 2002/58/EC), or ePrivacy Directive, may affect our marketing communications. Failure to comply with EU laws, including failure under the GDPR and UK GDPR, Data Protection Act 2018, ePrivacy Directive and other laws relating to the security of personal data may result in fines up to €20,000,000 (or £17,500,000 under the UK GDPR) or up to 4% of the total worldwide annual turnover of the preceding financial year, if greater, and other administrative penalties including criminal liability, which may be onerous and adversely affect our business, financial condition, results of operations and prospects. Failure to comply with the GDPR and related laws may also give risk to increase risk of private actions from data subjects

and consumer not-for-profit organizations, including a new form of class action that is available under the GDPR. Compliance with the GDPR and UK GDPR requires a rigorous and time-intensive process that may increase our cost of doing business or require us to change our business practices, and despite those efforts, there is a risk that we may be subject to the aforementioned fines and penalties, litigation, and reputational harm in connection with any European activities.

The UK is treated as a third country (for the purposes of data transfers). On June 28, 2021, the EU Commission published two adequacy decisions in respect of transfers under EU GDPR and the Law Enforcement Directive stating that the UK provides adequate protection for personal data transferred from the EU to the UK under EU GDPR. The adequacy decision is expected to last until June 27, 2025 but may end earlier, for example if an EU data subject or EU data protection authority challenges the adequacy decisions. In such a case, the Court of Justice of the European Union would need to determine whether the UK provides essentially equivalent protection.

The UK government has confirmed that the EEA is adequate, and so all transfers of personal data from the UK to the EEA will continue to be unrestricted after July 1, 2021.

The UK has issued a consultation with respect to future changes to data protection law. There is risk that in the event UK and EU data protection law diverges, that the adequacy decisions may come to an end. If this occurs, there will be cost implication due to dual compliance requirements and costs with respect to to international data transfers.

It is not always possible to identify and deter misconduct by employees or other parties. The precautions we take to detect and prevent this activity may not protect us from legal or regulatory action resulting from a failure to comply with applicable laws or regulations. Misconduct by our employees, principal investigators, consultants, commercial partners or vendors could result in significant financial penalties, criminal sanctions and thus have a material adverse effect on our business, including through the imposition of significant fines or other sanctions, and our reputation.

Risks Related to our Intellectual Property

Our success depends in part on our ability to protect our intellectual property and our proprietary technologies.

Our commercial success depends in part on our ability to obtain and maintain patent protection and trade secret protection for our product candidates, proprietary technologies, and their uses as well as our ability to operate without infringing upon the proprietary rights of others. We can provide no assurance that our patent applications or those of our licensors will result in additional patents being issued or that issued patents will afford sufficient protection against competitors with similar technologies, nor can there be any assurance that the patents issued will not be infringed, designed around or invalidated by third parties. Even issued patents may later be found unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. The degree of future protection for our proprietary rights is uncertain. Only limited protection may be available and may not adequately protect our rights or permit us to gain or keep competitive advantage. We have issued composition-of-matter patents in the United States and other countries for nomacopan, but we cannot be certain that the claims in our issued patents will not be found invalid or unenforceable if challenged. We cannot be certain that the claims in any patent applications covering our product candidates that are pending, or that we may file, will be considered patentable by the United States Patent and Trademark Office, or USPTO, and courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that the claims in our issued patents will not be found invalid or unenforceable if challenged. Even if any patent applications that we may file relating to specific formulations of our product candidates issue as patents, formulation patents protect a specific formulation of a product and may not be enforced against competitors making and marketing a product that has the same active pharmaceutical ingredient in a different formulation. Method-of-use patents protect the use of a product for the specified method or for treatment of a particular indication. This type of patent may not be enforced against competitors making and marketing a product that has the same active pharmaceutical ingredient for use in a method not claimed by the patent. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products “off-label.” Although off-label prescriptions may infringe or contribute to the infringement of method-of-use patents, the practice is common and such infringement may be difficult to prevent or prosecute. Also, as is the case for composition-of-matter patents, we cannot be certain that the claims in our issued method-of-use patents will not be found invalid or unenforceable if challenged. We cannot be certain that the claims in any patent applications covering methods of using our product candidates that are pending, or that we may file, will be considered patentable by the United States Patent and Trademark Office, or USPTO, and courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that the claims in our issued method-of-use patents will not be found invalid or unenforceable if challenged.

Our issued patents for nomacopan and its uses are expected to expire between 2024 and 2035 (excluding any patent term adjustment or potential patent term extension). Our pending patent applications for nomacopan and its uses, if issued, are expected to expire at various times that range from 2024 to 2040 (excluding any potential patent term adjustment or extension).

The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or any of our future development partners will be successful in protecting our product candidates by obtaining and defending patents. These risks and uncertainties include the following:

18

Table of Contents

In addition, we rely on the protection of our trade secrets and proprietary know-how. Although we have taken steps to protect our trade secrets and unpatented know-how, including entering into confidentiality agreements with third parties, and confidential information and inventions agreements with employees, consultants and advisors, we cannot provide any assurances that all such agreements have been duly executed, and third parties may still obtain this information or may come upon this or similar information independently. Enforcing a claim that a third party obtained illegally and is using trade secrets and/or proprietary know-how is expensive, time consuming and unpredictable. The enforceability of confidentiality agreements may vary from jurisdiction to jurisdiction. Additionally, if the steps taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating its trade secrets. If any of these events occurs or if we otherwise lose protection for our trade secrets or proprietary know-how, our business may be harmed.

Others may claim an ownership interest in our intellectual property, which could expose it to litigation and have a significant adverse effect on its prospects.

A third party may claim an ownership interest in one or more of our patents or other intellectual property. A third party could bring legal actions against us and seek monetary damages and/or enjoin clinical testing, manufacturing and marketing of the affected product or products. We cannot guarantee that a third-party will not assert a claim or an interest in any of such patents or intellectual property. If we become involved in any litigation, it could consume a substantial portion of our resources, and cause a significant diversion of effort by our technical and management personnel. If any of these actions are successful, in addition to any potential liability for damages, we could be required to obtain a license to continue to manufacture or market the affected product, in which case we may be required to pay substantial royalties or grant cross-licenses to our patents. We cannot, however, assure you that any such license will be available on acceptable terms, if at all. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations as a result of claims of patent infringement or violation of other IP rights, Further, the outcome of IP litigation is subject to uncertainties that cannot be adequately quantified in advance, including the demeanor and credibility of witnesses and the identity of the adverse party. This is especially true in IP cases that may turn on the testimony of experts as to technical facts upon which experts may reasonably disagree.

Changes in patent laws or patent jurisprudence could diminish the value of our patents, thereby impairing our ability to protect our products or product candidates.

As is the case with other biopharmaceutical companies, our success if heavily dependent on intellectual property, particularly patents. Obtaining and exploiting patents in the biopharmaceutical industry involve both technological and legal complexity. Therefore, obtaining and exploiting biopharmaceutical patents is costly, time-consuming and inherently uncertain. For example, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. These rulings have created uncertainty with respect to the validity and enforceability of patents, even once obtained. Depending on future actions and decisions by the U.S. Congress, the federal courts, and the U.S. Patent and Trademark Office, the laws and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to enforce our existing patents and patents that we may obtain in the future.

Risks Related to our Business Operations

Our business either directly or indirectly through critical suppliers may be adversely affected by the impact of COVID-19.

Public health epidemics or outbreaks could adversely impact our business. The situation surrounding the COVID-19 pandemic, including the mutation of variants, continues to remain fluid globally and we continue to manage ongoing challenges associated with the pandemic as they relate to operations. The potential for a material impact on our business, financial condition and results of operation remains a risk. We cannot reasonably estimate with any degree of certainty any future impact of COVID-19. Pandemics such as this can adversely impact our business as a result of disruptions, such as travel bans, quarantines, staffing shortages, and interruptions to access the trial sites and supply chains, which could result in material delays and complications with respect to our research and development programs and clinical trials.

Moreover, as a result of COVID-19, there is a general unease of conducting certain non-critical activities in medical centers. For example, while now open for enrollment, prior clinical trials have been halted or delayed due to COVID-19. The extent to which COVID-19 impacts operations will depend on future developments, including the scope of any new virus mutations and outbreaks, the nature of government public health guidelines and the public’s adherence to those guidelines, the rate of individuals becoming fully vaccinated and the public’s adherence to guidelines to receive booster vaccinations, and the extent to which new lockdowns may be needed or are required in particular countries, including China. In particular, the continued spread of COVID-19 globally could adversely impact our operations and workforce, including research and clinical trials and the ability to raise capital, could affect the operations of key governmental agencies, such as the FDA, which may delay the development of our product candidates, and could result in the inability of suppliers to deliver components or raw materials, including drug product and drug substance, on a timely basis or at all, each of which in turn could have an adverse impact on our business, financial condition and results of operation.

We currently have no marketing, sales or distribution infrastructure with respect to nomacopan. If we are unable to develop our sales, marketing and distribution capability on our own or through collaborations with partners, we may not be successful in commercializing our product candidates.

We currently have no marketing, sales or distribution capabilities and have limited sales or marketing experience within our organization. If our product candidate nomacopan is approved, we intend either to establish a sales and marketing organization with technical expertise and supporting distribution capabilities to commercialize nomacopan, or to outsource this function to a third party. Either of these options would be expensive and time consuming. Some or all of these costs may be incurred in advance of any approval of nomacopan. In addition, we may not be able to hire a commercial team in the United States or other target market that is sufficient in size or has adequate expertise in the medical markets that we intend to target. Any failure or delay in the development of our or third parties’ internal sales, marketing and distribution capabilities could adversely impact the commercialization of nomacopan and other future product candidates.

With respect to our existing and future product candidates, we may choose to collaborate with third parties that have direct sales forces and established distribution systems, either to augment or to serve as an alternative to our own sales force and distribution systems. Any future product revenue may be lower than if it directly marketed or sold any approved products. In addition, any revenue we receive will depend in whole or in part upon the efforts of these third parties, which may not be successful. If we are unable to enter into these arrangements on acceptable terms or at all, we may not be able to successfully commercialize our approved products. If we are not successful in commercializing our approved products, our future product revenue will suffer and we may incur significant losses.

We only have a limited number of employees to manage and operate our business.

As of December 31, 2021, we had nine full-time employees. Our limited financial resources have led us to focus on the development of nomacopan  and to manage and operate our business in a highly efficient manner. We cannot make assurances that we will be able to hire and/or retain adequate staffing levels to develop nomacopan or run our operations and/or to accomplish all of the objectives that we otherwise would seek to accomplish.

Our industry is highly competitive, and our product candidates may become obsolete.

We are engaged in a rapidly evolving field. Competition from other pharmaceutical companies, biotechnology companies and research and academic institutions is intense and likely to increase. Many of those companies and institutions have substantially greater financial, technical and human resources than us. Those companies and institutions also have substantially greater experience in developing products, conducting clinical trials, obtaining marketing authorization and in manufacturing and marketing biologic products. Our competitors may succeed in obtaining marketing authorization for their products more rapidly than we do. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competitive products. Our competitors may succeed in developing products that are more effective than those we are developing, or that would render our product candidates less competitive or even obsolete. In addition, one or more of our competitors may achieve product commercialization or patent protection, which could materially adversely affect our business.

If the FDA or other applicable regulatory authorities approve biosimilar products that compete with any of our or any of our partners’ products, the sales of our products would be adversely affected.

The Biologics Price Competition and Innovation Act, or BPCIA, was enacted in 2010, creating an abbreviated approval pathway for biosimilar products, referred to as the “351(k) pathway.” A biosimilar application must contain information demonstrating: (1) biosimilarity to the reference product through data derived from analytical studies, animal studies (including an assessment of toxicity), and clinical studies (including an assessment of immunogenicity and pharmacokinetics or pharmacodynamics), unless the FDA determines that such data are unnecessary, (2) sameness of strength, dosage form, and route of administration to the reference product as well as sameness of mechanism of action (to the extent known), (3) approval of the reference product for the conditions of use prescribed, recommended, or suggested in the labeling indications proposed for the biosimilar product, and (4) appropriate manufacturing, processing, packing, and holding facilities that meet the standards designed to ensure a safe, pure and potent medicine. Unless the FDA waives the requirement, clinical studies must be sufficient to show the safety, purity and potency of the proposed product for one or more “appropriate” conditions of use for which licensure is sought and for which the reference product is licensed.

If physicians and patients do not adopt our future products or if the market size for indications for which any product candidate is approved is smaller than expected, we may be unable to achieve forecasted revenues, if any.

Even if any of our product candidates obtain marketing authorization, they may not gain market acceptance among physicians, patients, or third-party payers. Physicians may decide not to recommend its treatments for a variety of reasons including:

21

Table of Contents

If any of our product candidates are approved, but fail to achieve market acceptance or such market is smaller than anticipated, we may not be able to achieve forecasted revenues, if any.

The uncertainty associated with biologics reimbursement and related matters may adversely affect our business.

Market acceptance and sales of any one or more of our product candidates will depend on reimbursement policies and may be affected by future healthcare reform measures in the United States and in foreign jurisdictions. Government authorities and third-party payers, such as private health insurers and health maintenance organizations, decide which drugs they will cover and establish payment levels. We cannot be certain that reimbursement will be available for any of our product candidates. Also, we cannot be certain that reimbursement policies will not reduce the demand for, or the price paid for, any future products. The insurance coverage and reimbursement status of newly-approved products is particularly uncertain, and failure to obtain or maintain adequate coverage and reimbursement for nomacopan or any other product candidates could limit our ability to generate revenue.

The United States and several foreign jurisdictions are considering, or have already enacted, a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell future products profitably. There is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access to healthcare. In the United States, the pharmaceutical industry has been a particular focus of these efforts. We may experience pricing pressures in connection with the sale of any products that we develop due to the trend toward managed healthcare, increasing influence of health maintenance organizations and additional legislative proposals.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, PPACA, became law in the United States. Since its enactment, there have been judicial and Congressional challenges to certain aspects of the PPACA. Congress and Former President Trump have expressed their intentions to repeal or repeal and replace the PPACA. Former President Trump issued an Executive Order and both chambers of Congress passed bills, all with the goal of fulfilling their intensions. However, to date, the Executive Order has had limited effect and the Congressional activities have not resulted in the passage of a law. If a law is enacted, many if not all of the provisions of the PPACA may no longer apply to prescription drugs. While we are unable to predict what changes may ultimately be enacted, to the extent that future changes affect how any future products are paid for and reimbursed by government and private payers our business could be adversely impacted. In November 2020, Joseph Biden was elected President and, in January 2021, the Democratic Party obtained control of the Senate. As a result of these electoral developments, it is unlikely that continued legislative efforts will be pursued to repeal PPACA. Instead, it is possible that legislation will be pursued to enhance or reform PPACA. We are not able to state with certainty what the impact of potential legislation will be on our business.

In December 2020, the Department of Health and Human Services has published a final regulation that may significantly restrict the availability of certain regulatory safe harbors under the federal Anti-Kickback Statute, effective January 1, 2022, that are used to facilitate certain types of transactions between manufacturers and pharmacy benefits managers that play a significant role in the pharmaceutical distribution chain. These changes to the Discount Safe Harbors available under the Anti-Kickback Statute would reduce some of the protections currently available to manufacturers that pay negotiated rebates to pharmacy benefits managers in exchange for these “PBMs” agreeing to include drugs and biologics on the formularies of the PBM’s downstream customers, primarily the health plans that insure patients for both private commercial plans and government-sponsored plans. The Pharmaceutical Care Management Association has filed a lawsuit challenging this rule under the Administrative and Procedures Act. Should the regulation go into effect in 2022, it could have an impact on both our commercial supply arrangements with health plans and our supply arrangements to health plans that serve beneficiaries of federal health care programs such as Medicare Part D.

On January 5, 2017, the Health Resources and Services Administration (HRSA) at the U.S. Department of Health and Human Services (HHS) issued a final rule implementing Civil Monetary Penalties for manufacturers who knowingly and intentionally charge a covered entity more than the 340B ceiling price for a covered outpatient drug, as well as providing clarity as to the calculation of the 340B ceiling price. The final rule became effective on January 1, 2019. Since the final rule became effective, the HRSA has audited a number of manufacturers and concluded that they violated the 340B ceiling price requirement in some instances, suggesting that manufacturers are now at a higher risk of enforcement action for ceiling price noncompliance.

If product liability lawsuits are successfully brought against us or any of our collaborative partners, we may incur substantial liabilities and may be required to limit commercialization of our products.

We face an inherent risk of product liability lawsuits related to the testing of our product candidates in seriously ill patients and may face an even greater risk if product candidates are approved by regulatory authorities and introduced commercially. Product liability claims may be brought against us or our partners by participants enrolled in our clinical trials, patients, health care providers or others using, administering or selling any of our future approved products. If we cannot successfully defend ourselves against any such claims, we may incur substantial liabilities, which may result in:

Although we currently carry clinical trial insurance, the amount of such insurance coverage may not be adequate. In addition, we will need to obtain more comprehensive insurance and increase our insurance coverage when we begin the commercialization of our product candidates. Insurance coverage is becoming increasingly expensive. As a result, we may be unable to maintain or obtain sufficient insurance at a reasonable cost to protect us against losses that could have a material adverse effect on our business.

We enter into various contracts in the normal course of our business in which we indemnify the other party to the contract. In the event we have to perform under these indemnification provisions, it could have a material adverse effect on our business, financial condition and results of operations.

In the normal course of business, we periodically enter into academic, commercial, service, collaboration, licensing, consulting, investor relations and other agreements that contain indemnification provisions. With respect to our academic and other research agreements, we typically indemnify the institution and related parties from losses arising from claims relating to the products, processes or services made, used, sold or performed pursuant to the agreements for which we have secured licenses, and from claims arising from our or our sublicensees’ exercise of rights under the agreement. With respect to our commercial agreements, we may be required to indemnify our vendors from any third-party product liability claims that could result from the production, use or consumption of the product, as well as for alleged infringements of any patent or other intellectual property right by a third party. With respect to investor relations agreements, we may indemnify the counterparty for losses resulting from our negligence or our supply of inaccurate information.

Should our obligation under an indemnification provision exceed applicable insurance coverage or if we were denied insurance coverage, our business, financial condition and results of operations could be adversely affected. Similarly, if we are relying on a collaborator to indemnify us and the collaborator is denied insurance coverage or the indemnification obligation exceeds the applicable insurance coverage and does not have other assets available to indemnify us, our business, financial condition and results of operations could be adversely affected.

Our business and operations would suffer in the event of computer system failures or security breaches.

Despite the implementation of security measures, our internal computer systems, and those of our contract research organizations, or CROs and other third parties on which we rely, are vulnerable to damage from computer viruses, unauthorized access, cyber-attacks, natural disasters, fire, terrorism, war, and telecommunication and electrical failures.  If such an event were to occur and interrupt our operations, it could result in a material disruption of our drug development programs.  For example, the loss of clinical trial data from ongoing or planned clinical trials could result in delays in our marketing authorization efforts and significantly increase our costs to recover or reproduce the data.  To the extent that any disruption or security breach results in a loss of or damage to our data or applications, loss of trade secrets or inappropriate disclosure of confidential or proprietary information, including protected health information or personal data of employees or former employees, access to our clinical data, or disruption of the manufacturing process, we could incur liability and the further development of our drug candidates could be delayed.  We may also be vulnerable to cyber-attacks by hackers or other malfeasance.  This type of breach of our cybersecurity may compromise our confidential information and/or our financial information and adversely affect our business or result in legal proceedings. If security breaches result in the loss of clinical trial data or other confidential information, we may be the subject of legal proceedings and suffer financial and reputational damage. Further, these cybersecurity breaches may inflict reputational harm upon us that may result in decreased market value and erode public trust.

During the preparation of our 2020 Form 20-F, we identified certain misstatements to our previously issued financial statements and previously restated certain of our consolidated financial statements. If we discover errors in our financial statements and are required to restate in the future, it could create additional risks and uncertainties that may have a material adverse effect on our business, financial position and results of operations.

In our Annual Report on Form 20-F for the year ended December 31, 2020, we discovered an error in our accounting treatment of certain options from 2015 that should have been accounted for as an equity instrument as opposed to a liability. Accordingly, we concluded that the financial statements contained in our Annual Reports on Form 20-F for the years ended December 31, 2015 through 2019, as well as the interim condensed consolidated financial statements contained in the quarterly reports on Form 6-K for each quarter within these years, as well as the quarterly periods ended March 31, 2020, June 2020 and September 2020, should be restated and therefore not relied upon. This was non-cash restatement and the options did not constitute a legal liability to us and will not affect our financial statements upon settlement. We have included restated financial statements and notes thereto and any other appropriate revisions in this Annual Report on Form 20-F for the year ended December 31, 2021.

As a result of these errors and the restatement, we became subject to a number of additional risks and uncertainties and unanticipated costs for accounting, legal and other fees and expenses. We may become subject to legal proceedings brought by regulatory or governmental authorities, or subject to other legal proceedings, as a result of the errors or the related restatement, which could result in a loss of investor confidence and other reputational harm, the loss of key employees, additional legal and other costs. Any of the foregoing impacts, individually or in aggregate, may have a material adverse effect on our business, financial position and results of operations.

We or the third parties upon whom we depend may be adversely affected by natural disasters and/or health epidemics and pandemics, and our business continuity and disaster recovery plans may not adequately protect us from  natural disasters and/or health epidemics and pandemics.

Natural disasters could severely disrupt our operations, and have a material adverse effect on our business, results of operations, financial condition and prospects. If a natural disaster, power outage, health epidemics or other event occurred that prevented us from using all or a significant portion of our office, that damaged critical infrastructure, such as the manufacturing facilities of our third-party contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. As the global supply chain continues to see disruptions, there is higher risk for continued labor shortages, reduced labor capacity at supplier and third-party manufacturers, increased raw material costs and delays in production of our clinical product and clinical trials that will adversely impact our business. The extent to which the global supply chain disruptions may continue to impact our results of operations, including the long-term nature of the impact, depends on numerous evolving factors, which are highly uncertain and difficult to predict.

In particular, the continued spread of COVID-19 globally could adversely impact our operations and workforce, including research and clinical trials and the ability to raise capital, could affect the operations of key governmental agencies, such as the FDA, which may delay the development of our product candidates, and could result in the inability of suppliers to deliver components or raw materials, including drug product and drug substance, on a timely basis or at all, each of which in turn could have an adverse impact on our business, financial condition and results of operation.

If we fail to develop and commercialize other product candidates, we may be unable to generate revenues.

Although the development and commercialization of nomacopan is our primary focus, as part of our longer-term growth strategy, we may evaluate the development and commercialization of other therapies related to immune-mediated, inflammatory, orphan and other diseases. We may from time to time evaluate internal opportunities from our current product candidates, and also may choose to in-license or acquire other product candidates as well as commercial products to treat patients suffering from immune-mediated, orphan or other disorders with high unmet medical needs and limited treatment options. These other product candidates will require additional, time-consuming development efforts prior to commercial sale, including preclinical studies, clinical trials and approval by the FDA, MHRA, EMA and/or applicable foreign regulatory authorities. All product candidates are prone to the risks of failure that are inherent in pharmaceutical product development, including the possibility that the product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities. In addition, we cannot assure you that any such products that are approved will be manufactured or produced economically, successfully commercialized or widely accepted in the marketplace or be more effective than other commercially available alternatives.

Our business could suffer if we are unable to attract and retain key employees.

Our success depends upon the continued service and performance of our senior management and other key personnel. The loss of the services of these personnel could delay or prevent the successful completion of our planned clinical trials or the commercialization of our therapeutic candidates or otherwise affect our ability to manage our company effectively and to carry out our business plan. We do not maintain key-man life insurance. Although we have entered into employment agreements with all of the members of our senior management team, members of our senior management team may resign at any time. High demand exists for senior management and other key personnel in the biopharmaceutical industry. There can be no assurance that we will be able to continue to retain and attract such personnel.

Our growth and success also depend on our ability to attract and retain additional highly qualified scientific, technical, sales, managerial and finance personnel. We experience intense competition for qualified personnel, and the existence of non-competition agreements between prospective employees and their former employers may prevent us from hiring those individuals or subject us to suit from their former employers. In addition, if we elect to independently commercialize any therapeutic candidate, we will need to expand our marketing and sales capabilities. While we attempt to provide competitive compensation packages to attract and retain key personnel, many of our competitors are likely to have greater resources and more experience than we have, making it difficult for us to compete successfully for key personnel. If we cannot attract and retain sufficiently qualified technical employees on acceptable terms, we may not be able to develop and commercialize competitive products. Further, any failure to effectively integrate new personnel could prevent us from successfully growing our company.

Class action lawsuits against us could lead to adverse outcomes.

We have in the past been, and may in the future become subject to class action litigation. In May 2017, putative class actions asserting violations of Sections 10(b) and 20(a) of the Exchange Act, based primarily on our press releases or statements concerning the Phase II PNH trial of nomacopan and a report issued on April 26, 2017 titled “Akari’s Coversin matches Soliris® in Phase II”, or the Edison Report, by Edison Investment Research Ltd, or Edison, about us and actions taken by us after the report was issued were commenced in the U.S. District Court for the Southern District of New York against us, a former Chief Executive Officer and our former Chief Financial Officer. These actions were consolidated, and plaintiffs amended their pleadings to include our Executive Chairman and Edison as defendants. On June 8, 2018, the parties entered into a memorandum of understanding to settle plaintiffs’ claims for a total payment of $2.7 million in cash. On July 26, 2018, plaintiffs filed a notice with the Court voluntarily dismissing Edison from the action. On August 3, 2018, the remaining parties executed and filed a stipulation and agreement of settlement (the terms of which were consistent with the memorandum of understanding). On August 7, 2018, the Court granted plaintiffs’ motion for preliminary approval of the settlement, and on November 28, 2018, following a hearing with the parties, the court ordered final approval of the settlement. Plaintiffs subsequently moved to distribute the settlement funds to the class, and the Court granted plaintiffs’ motion on February 4, 2019. Separately, Edison Investment Research Ltd. sought indemnification from us including reimbursement of all legal expenses that Edison incurs in connection with the securities class action (to which, as discussed above, Edison was added as a defendant) and lost profits from customer relationships that Edison claims it lost as a result of the retraction of the Edison Report. The parties have finalized and consummated a settlement and the settlement payment has been made. If we become subject to any future class action litigation, we could incur substantial costs not covered by our liability insurance, suffer a significant adverse impact on our reputation and this could divert management’s attention and resources from other priorities, any of which could have a material adverse effect on our business. In addition, any of these matters could require payments that are not covered by, or exceed the limits of, our available liability insurance, which could have a material adverse effect on our business, financial condition and results of operation.

​

Risks Related to Our Reliance on Third Parties

We seek to partner with third-party collaborators with respect to aspects of the development and commercialization of our product candidates and we may not succeed in establishing and maintaining collaborative relationships, which may significantly limit our ability to develop and commercialize our product candidates successfully, if at all.

Our business strategy relies in part on partnering with pharmaceutical companies to supplement our internal development efforts. If we are not able to enter into collaboration arrangements, we may be required to undertake and fund further development, clinical trials, manufacturing and commercialization activities solely at our own expense and risk. If we are unable to finance and/or successfully execute those activities, or we delay such activities due to capital availability, our business could be materially and adversely affected, and potential future product launches could be materially delayed, be less successful, or we may be forced to discontinue clinical development of product candidates.

The process of establishing and maintaining collaborative relationships is difficult, time-consuming and involves significant uncertainty, including if a collaboration partner:

26

Table of Contents

If any collaborator fails to fulfill its responsibilities in a timely manner, or at all, our research, clinical development, manufacturing or commercialization efforts related to that collaboration could be delayed or terminated, or it may be necessary for us to assume responsibility for expenses or activities that would otherwise have been the responsibility of our collaborator. If we are unable to establish and maintain collaborative relationships on acceptable terms or to successfully transition terminated collaborative agreements, we may have to delay or discontinue further development of one or more of our product candidates, undertake development and commercialization activities at our own expense or find alternative sources of capital.

If the third parties on which we rely for our clinical trials and results do not perform our clinical trial activities in accordance with good clinical practices and related regulatory requirements, we may be unable to obtain marketing authorization for or commercialize our product candidates.

We use and heavily rely on third-party contract research organizations to conduct and/or oversee the clinical trials of our product candidates and expect to continue to do so for the foreseeable future. Nonetheless, we are responsible for confirming that each of our clinical trials is conducted in accordance with the FDA’s, MHRA’s and/or EMA’s requirements and its general investigational plan and protocol.

The FDA, MHRA and EMA require us and our contract research organizations to comply with regulations and standards, commonly referred to as good clinical practices, for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the trial participants are adequately protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Third parties may not complete activities on schedule or conduct our clinical trials in accordance with regulatory requirements or the respective trial plans and protocols. In addition, third parties may not be able to repeat their past successes in clinical trials. The third parties’ failure to carry out their obligations could delay or prevent the development, approval and commercialization of our product candidates or result in enforcement action against us.

Use of third parties to manufacture our product candidates may increase the risk that we will not have sufficient quantities of our product candidates, products, or necessary quantities at an acceptable cost.

We do not own or operate manufacturing facilities for the production of clinical or commercial quantities of our product candidates, and we lack the resources and the capabilities to do so. As a result, we currently rely on third parties for supply of the active pharmaceutical ingredients, or API, in our product candidates. Our strategy is to outsource all manufacturing of our product candidates and products to third parties.

We currently engage a third-party manufacturer to provide clinical material of the API, lyophilization, release testing and fill and finish services for the final drug product formulation of nomacopan that is being used in our clinical trials. Although we believe that there are several potential alternative manufacturers who could manufacture nomacopan, we may incur added costs and delays in identifying and qualifying any such replacement. In addition, we have not yet concluded a commercial supply contract with any commercial manufacturer. There is no assurance that we will be able to timely secure needed supply arrangements on satisfactory terms,

27

Table of Contents

or at all. Our failure to secure these arrangements as needed could have a material adverse effect on our ability to complete the development of our product candidates or to commercialize them. We may be unable to conclude agreements for commercial supply with third-party manufacturers, or may be unable to do so on acceptable terms. There may be difficulties in scaling up to commercial quantities and formulation of nomacopan and the costs of manufacturing could be prohibitive.

Even if we are able to establish and maintain arrangements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including:

If we do not maintain our key manufacturing relationships, we may fail to find replacement manufacturers or develop our own manufacturing capabilities, which could delay or impair our ability to obtain marketing authorization for our products. If we do find replacement manufacturers, we may not be able to enter into agreements with them on terms and conditions favorable to us and there could be a substantial delay before new facilities could be qualified and registered with the FDA and other foreign regulatory authorities.

The FDA, MHRA EMA and other foreign regulatory authorities require manufacturers to register manufacturing facilities. The FDA and corresponding foreign regulators also inspect these facilities to confirm compliance with current good manufacturing practices, or cGMPs. Contract manufacturers may face manufacturing or quality control problems causing drug substance production and shipment delays or a situation where the contractor may not be able to maintain compliance with the applicable cGMP requirements. Any failure to comply with FDA, MHRA, EMA and comparable foreign regulatory requirements could adversely affect our clinical research activities and our ability to develop our product candidates and market our products.

Moreover, the manufacturing of therapeutic biologics products is highly complex. Problems may arise during manufacturing for a variety of reasons, including but not limited to:

28

Table of Contents

Products with quality issues may have to be discarded, resulting in product shortages or additional expenses. This could lead to, among other things, increased costs, lost revenue, damage to customer relationships, time and expense spent investigating the cause and, depending on the cause, similar losses with respect to other batches or products. If problems are not discovered before the product is released to the market, recall and product liability costs may also be incurred.

Manufacturing methods and formulation are sometimes altered through the development of drug candidates from clinical trials to approval, and further to commercialization, in an effort to optimize manufacturing processes and results. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause the drug candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the altered materials. This could delay the commercialization of drug candidates and require bridging studies or the repetition of one or more clinical trials, which may result in increases in clinical trial costs, delays in drug approvals and jeopardize our ability to commence product sales and generate revenue.

We may also encounter problems with achieving adequate or clinical-grade or commercial grade products that meet FDA or other comparable regulatory agency standards or specifications, maintaining consistent and acceptable production costs, and experience shortages of qualified personnel, raw materials or key contractors, and experience unexpected damage to our facilities or the equipment in them. In these cases, we may be required to delay or suspend our manufacturing activities. We may be unable to secure temporary, alternative manufacturers for our drugs with the terms, quality and costs acceptable to us, or at all. Such an event could delay our clinical trials and/or the availability of our products for commercial sale. Moreover, we may spend significant time and costs to remedy these deficiencies before we can continue production at our manufacturing facilities.

In addition, the quality of our products, including drug candidates manufactured by us for research and development purposes and drugs manufactured by us for commercial use, depends significantly on the effectiveness of our quality control and quality assurance, which in turn depends on factors such as the production processes used in our manufacturing facilities, the quality and reliability of equipment used, the quality of our staff and related training programs and our ability to ensure that our employees adhere to our quality control and quality assurance protocol. However, we cannot assure you that our quality control and quality assurance procedures will be effective in consistently preventing and resolving deviations from our quality standards. Any significant failure or deterioration of our quality control and quality assurance protocol could render our products unsuitable for use, jeopardize any cGMP certifications we may have and/or harm our market reputation and relationship with business partners. Any such developments may have a material adverse effect on our business, financial condition and results of operations.

If our third-party manufacturer of nomacopan is unable to increase the scale of its production of nomacopan, and/or increase the product yield of its manufacturing, then our costs to manufacture the product may increase and commercialization may be slowed.

In order to produce sufficient quantities of nomacopan to meet the demand for clinical trials and subsequent commercialization, our third party manufacturer of nomacopan will be required to increase its production while maintaining the quality of the product. The transition to larger scale production could prove difficult. In addition, if our third party manufacturer is not able to optimize its manufacturing process to increase the product yield for nomacopan, or if it is unable to produce increased amounts of nomacopan while maintaining the quality of the product, then we may not be able to meet the demands of clinical trials or market demands, which could decrease our ability to generate profits and have a material adverse impact on our business and results of operation.

Risks Related to our Ordinary Shares and ADSs

Ownership of our ADSs and/or ordinary shares involves a high degree of risk.

Investing in and owning our ADSs and ordinary shares involve a high degree of risk. Shareholders should read carefully the risk factors provided within this section, as well as our public documents filed with the SEC, including the financial statements therein.

We are currently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability due to the ongoing military conflict between Russia and Ukraine.

U.S. and global markets are experiencing volatility and disruption following the escalation of geopolitical tensions and the start of the military conflict between Russia and Ukraine. In February 2022, Russia launched a full-scale military invasion of Ukraine. Although the length and impact of the ongoing military conflict is highly unpredictable, the conflict in Ukraine could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets. Additionally, Russia’s prior annexation of Crimea, recent recognition of two separatist republics in the Donetsk and Luhansk regions of Ukraine and subsequent military interventions in Ukraine have led to sanctions and other penalties being levied by the United States, European Union and other countries against Russia, Belarus, the Crimea Region of Ukraine, the so-called Donetsk People’s Republic, and the so-called Luhansk People’s Republic, including agreement to remove certain Russian financial institutions from the Society for Worldwide Interbank Financial Telecommunication (SWIFT) payment system. Additional potential sanctions and penalties have also been proposed and/or threatened. Russian military actions and the resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets, potentially making it more difficult for us to obtain additional funds. Any of the abovementioned factors could affect our business, prospects, financial condition, and operating results. The extent and duration of the military action, sanctions and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions may also magnify the impact of other risks described in this Annual Report on Form 20-F.

We identified a material weakness in our internal control over financial reporting in 2021, and in the future, we may identify additional material weaknesses or fail to maintain an effective system of controls. If we identify additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect our business and stock price.

The Sarbanes-Oxley Act of 2002 requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we are required, under Section 404 of the Sarbanes-Oxley Act of 2002, to perform system and process evaluations and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting. This assessment must include disclosure of any material weaknesses in our internal control over financial reporting identified by our management. A material weakness is a control deficiency, or combination of control deficiencies, in internal control over financial reporting that results in more than a reasonable possibility that a material misstatement of annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

We identified a material weakness in our internal control over financial reporting in 2021, and concluded that our internal control over financial reporting was not effective as of December 31, 2020, which resulted in an error in the accounting treatment of the RPC options, or the RPC Options. We remediated the material weakness regarding the RPC Options in 2021, which were originally recorded as a $26 million liability (as related to options and warrants), by re-classifying and re-valuing the RPC Options in the year ended December 31, 2015 (and for each subsequent year) as $22.6 million of equity (additional paid-in capital) as discussed in “Item 15. Controls and Procedures” of this Annual Report on Form 20-F. In addition, we updated our policies and procedures regarding the accounting for significant non-routine transactions, specifically to periodically re-evaluate the accounting analysis and conclusions of these transactions to ensure that the accounting conclusions reached at the inception of the transaction remain appropriate.

We cannot assure you that the measures we have taken to date and may take in the future will be sufficient to prevent or avoid potential future material weaknesses. The effectiveness of our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the possibility of human error, and the risk of fraud. If we are unable to prevent or avoid future material weaknesses, our ability to record, process, and report financial information accurately, and to prepare financial statements within the time periods specified by the forms of the SEC, could be adversely affected which, in turn, may adversely affect our reputation and business and the market price of our common stock. In addition, any such failures could result in litigation or regulatory actions by the SEC or other regulatory authorities,

30

Table of Contents

loss of investor confidence, delisting of our securities, and harm to our reputation and financial condition, or diversion of financial and management resources from the operation of our business.

In addition, it is possible that control deficiencies could be identified by our management or by our independent registered public accounting firm in the future or may occur without being identified. Such a failure could result in regulatory scrutiny and cause investors to lose confidence in our reported financial results, lead to a default under our current or future indebtedness and otherwise have a material adverse effect on our business, financial condition, cash flows, or results of operations.

Our management has concluded that our disclosure controls and procedures were ineffective.

Our management has concluded that our disclosure controls and procedures for the fiscal year ended December 31, 2020 were not effective for the fiscal year ended December 31, 2020 due to the material weakness noted above. See “Item 15. Controls and Procedures.”  If we do not effectively remediate the material weakness identified, we may not be able to accurately report our financial condition, results of operations or cash flows on a timely basis, which may adversely affect investor confidence in us.

Our disclosure controls and internal controls and procedures may not prevent all errors and all fraud.  A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.  Further, the design of a control system reflects that there are resource constraints, and the benefits of controls must be considered relative to their costs.  Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all our control issues and instances of fraud, if any, have been or will be detected.  These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur simply because of error or mistake.  Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by circumvention of the internal control procedures.  The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate.  Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.

If we are deemed or become a passive foreign investment company, or PFIC, for U.S. federal income tax purposes in 2022 or in any prior or subsequent years, there may be negative tax consequences for U.S. taxpayers that are holders of our ADSs.

We will be treated as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes in any taxable year in which either (i) at least 75% of our gross income is “passive income” or (ii) on average at least 50% of our assets by value produce passive income or are held for the production of passive income. Passive income for this purpose generally includes, among other things, certain dividends, interest, royalties, rents and gains from commodities and securities transactions and from the sale or exchange of property that gives rise to passive income. Passive income also includes amounts derived by reason of the temporary investment of funds, including those raised in a public offering. In determining whether a non-U.S. corporation is a PFIC, a proportionate share of the income and assets of each corporation in which it owns, directly or indirectly, at least a 25% interest (by value) is taken into account.

We believe we were not a PFIC for 2021.  Because the PFIC determination is highly fact sensitive, there can be no assurance that we will not be a PFIC for 2022 or for any other taxable year. If we were to be characterized as a PFIC for U.S. federal income tax purposes in any taxable year during which a U.S. shareholder owns our ADSs, and such U.S. shareholder does not make an election to treat us as a “qualified electing fund,” or QEF, or make a “mark-to-market” election, then “excess distributions” to such U.S. shareholder, and any gain realized on the sale or other disposition of our ADSs will be subject to special rules. Under these rules: (i) the excess distribution or gain would be allocated ratably over the U.S. shareholder’s holding period for ADSs; (ii) the amount allocated to the current taxable year and any period prior to the first day of the first taxable year in which we were a PFIC would be taxed as ordinary income; and (iii) the amount allocated to each of the other taxable years would be subject to tax at the highest rate of tax in effect for the applicable class of taxpayer for that year, and an interest charge for the deemed deferral benefit would be imposed with respect to the resulting tax attributable to each such other taxable year. In addition, if the U.S. Internal Revenue Service, or IRS, determines that we are a PFIC for a year with respect to which we have determined that we were not a PFIC, it may be too late for a U.S. shareholder to make a timely QEF or mark-to-market election. U.S. shareholders who hold our ADSs during a period when we are a PFIC will be generally subject to the foregoing rules, even if we cease to be a PFIC in subsequent years, subject to certain exceptions, including for U.S. shareholders who made a timely QEF or mark-to-market election. A U.S. shareholder can make a QEF election by completing the relevant portions of and filing IRS Form 8621 in accordance with the instructions thereto. A QEF election generally may not be revoked

31

Table of Contents

without the consent of the IRS. If an investor provides reasonable notice to us that it has determined to make a QEF election, we intend to provide annual financial information to such investor as may be reasonably required for purposes of filing United States federal income tax returns in connection with such QEF election.

U.S. investors are urged to consult their own tax advisors regarding the possible application of the PFIC rules.

Our ADSs may be involuntarily delisted from trading on the Nasdaq Capital Market if we fail to comply with the continued listing requirements. A delisting of our ADSs is likely to reduce the liquidity of our ADSs and may inhibit or preclude our ability to raise additional financing.

Nasdaq requires us to meet certain financial, public float, bid price and liquidity standards on an ongoing basis in order to continue the listing of our ADSs. Generally, we must maintain a minimum amount of shareholders equity (generally $2.5 million) and a minimum closing bid price (generally $1.00). If we fail to meet any of the continuing listing requirements, our ADSs may be subject to delisting and we may become subject to delisting proceedings. If our ADSs are delisted and we are not able to list our ADSs on another national securities exchange, we expect our securities would be quoted on an over-the-counter market. If this were to occur, our shareholders could face significant material adverse consequences, including limited availability of market quotations for our ADSs and reduced liquidity for the trading of our securities. In addition, we could experience a decreased ability to issue additional securities and obtain additional financing in the future. There can be no assurance that an active trading market for our ADSs will develop or be sustained. We may choose to raise additional capital in order to increase our shareholders’ equity in order to meet the Nasdaq continued listing standards. Any additional equity financings may be financially dilutive to, and will be dilutive from an ownership perspective to our shareholders, and such dilution may be significant based upon the size of such financing. Additionally, we cannot assure that such funding will be available on a timely basis, in needed quantities, or on terms favorable to us, if at all.

The market price of our ADSs may be volatile and may fluctuate in a way that is disproportionate to our operating performance.

Our stock price may experience substantial volatility as a result of a number of factors. The market prices for securities of biotechnology companies in general have been highly volatile and may continue to be so in the future. The following factors, in addition to other risk factors described in this section, may have a significant impact on the market price of our ADSs:

32

Table of Contents

33

Table of Contents

The stock markets in general, and the markets for biotechnology stocks in particular, have experienced significant volatility that has often been unrelated to the operating performance of particular companies. The financial markets continue to face significant uncertainty, resulting in a decline in investor confidence and concerns about the proper functioning of the securities markets, which decline in general investor confidence has resulted in depressed stock prices for many companies notwithstanding the lack of a fundamental change in their underlying business models or prospects. These broad market fluctuations may adversely affect the trading price of our ADSs.

In the past, class action litigation has often been instituted against companies whose securities have experienced periods of volatility in market price. Any such litigation brought against us, could result in substantial costs, which could hurt our financial condition and results of operations and divert management’s attention and resources, which could result in delays of our clinical trials or commercialization efforts.

Insiders have control over us which could delay or prevent a change in corporate control or result in the entrenchment of management and/or the board of directors.

As of April 30, 2022, our directors and executive officers, together with their affiliates and related persons, beneficially own, in the aggregate, approximately 18.2% of our outstanding ordinary shares. Our chairman Dr. Ray Prudo, beneficially owns approximately 17.6% of our outstanding ordinary shares. In addition, as of such date, and based on information provided to us by Aspire Capital, Aspire Capital beneficially owns approximately 18.6% of our outstanding ordinary shares. Accordingly, these shareholders, if acting together, or Dr. Prudo or Aspire Capital, individually, may have the ability to impact the outcome of matters submitted to our shareholders for approval, including the election and removal of directors and any merger, consolidation, or sale of all or substantially all of our assets. In addition, these persons may have the ability to influence the management and affairs of our Company. Accordingly, this concentration of ownership may harm the market price of our ADSs by:

Future sales and issuances of our ordinary shares or ADSs or rights to purchase ordinary shares or ADSs pursuant to our equity incentive plans could result in additional dilution of the percentage ownership of our shareholders and could cause our share price to fall.

We expect that significant additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing equity securities, our shareholders may experience substantial dilution. We may sell ordinary shares (which may be represented by ADSs), convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell ordinary shares, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to our existing

34

Table of Contents

shareholders, and new investors could gain rights superior to our existing shareholders. Additionally, any ordinary shares or ADSs issued pursuant to our equity incentive plan may result in material dilution to our existing shareholders.

Sales of a substantial number of our ADSs by our existing shareholders in the public market could cause our stock price to fall.

Sales of a substantial number of our ADSs in the public market or the perception that these sales might occur, could significantly reduce the market price of our ADSs and impair our ability to raise adequate capital through the sale of additional equity securities.

The withdrawal of the United Kingdom from the European Union (Brexit) could adversely affect our business, financial condition, results of operations and prospects.

Prior to January 1, 2021, the UK was part of the EU so that there was some commonality with respect to EU laws and the UK was a member of the Customs Union and the Single Market.

Since January 1, 2021 the UK is no longer part of the EU and is considered by the EU as a “third country”. The trade relationship between the EU and the UK is principally governed by a trade and co-operation agreement, or the EU-UK Trade Agreement. Alongside agreements for co-operation on economic, social, environmental and other matters, the EU-UK Trade Agreement incorporates an extensive free trade agreement that provides for zero tariffs and quotas on goods, provided that certain conditions are met. Nevertheless, additional administrative and regulatory burdens may increase costs. Following Brexit, EU laws were mostly transitioned into UK law but UK laws may diverge in future from those in the EU. Parallel regulatory regimes could result in the regulatory compliance and patent costs associated with our business increasing significantly so as to adversely affect our financial condition, results of operations and prospects. Further, our regulatory compliance costs may increase, as the UK has adopted standalone UK medicines regulations. The UK medicines regulatory regime is currently similar to EU regulations but the UK has enacted the Medicines and Medical Devices Act 2021, under which the UK may adopt changed regulations which may diverge from the EU legislative regime for medicines, their research, development and commercialization. Separate regulatory regimes will require us to comply with separate regimes in the UK and the EU, or to develop new policies and procedures or reorganize our operations, any of which could increase our compliance costs. The challenges faced by the UK following Brexit could result in an overall decline in trade and economic growth and/or an increase in economic volatility. Any of the aforementioned possible effects of Brexit, and others that we cannot anticipate, may materially adversely affect our business, financial condition, results of operations and prospects.

Provisions in our Articles of Association and under English law could make an acquisition of our Company more difficult and may prevent attempts by our shareholders to replace or remove our organization management.

Provisions in our Articles of Association may delay or prevent an acquisition or a change in management. These provisions include a staggered board and prohibition on actions by written consent of our shareholders. Although we believe these provisions collectively will provide for an opportunity to receive higher bids by requiring potential acquirors to negotiate with our board of directors, they would apply even if the offer might be considered beneficial by some shareholders. In addition, these provisions may frustrate or prevent any attempts by our shareholders to replace or remove then current management by making it more difficult for shareholders to replace members of the board of directors, which is responsible for appointing the members of management.

We do not anticipate paying cash dividends, and accordingly, shareholders must rely on appreciation in our ADSs for any return on their investment.

We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Therefore, the success of an investment in our ADSs will depend upon any future appreciation in their value. There is no guarantee that our ADSs will appreciate in value or even maintain the price at which our shareholders have purchased their shares.

We incur significant costs and demands upon management as a result of complying with the laws and regulations affecting public companies, which could harm our operating results.

As a public company, we incur significant legal, accounting and other expenses, including costs associated with public company reporting requirements. We also incur costs associated with current corporate governance requirements, including requirements under Section 404 and other provisions of the Sarbanes-Oxley Act of 2002, as well as rules implemented by the SEC and the Nasdaq Stock

35

Table of Contents

Market. The expenses incurred by public companies for reporting and corporate governance purposes have increased dramatically in recent years.

We are a “foreign private issuer” and as a result of this and other reduced disclosure requirements applicable to foreign private issuers, our ADSs may be less attractive to investors.

As a foreign private issuer, we are not subject to the same requirements that are imposed upon U.S. domestic issuers by the SEC. Under the Exchange Act, we are subject to reporting obligations that, in certain respects, are less detailed and less frequent than those of U.S. domestic reporting companies. For example, we will not be required to issue proxy statements that comply with the requirements applicable to U.S. domestic reporting companies. We will also have four months after the end of each fiscal year to file our annual reports with the SEC and will not be required to file current reports as frequently or promptly as U.S. domestic reporting companies. Furthermore, our officers, directors, and principal shareholders will be exempt from the requirements to report transactions in our equity securities and from the short-swing profit liability provisions contained in Section 16 of the Exchange Act. These exemptions and leniencies, along with other corporate governance exemptions resulting from our ability to rely on home country rules, will reduce the frequency and scope of information and protections to which you may otherwise have been eligible in relation to U.S. domestic reporting companies. If we were to lose our foreign private issuer status, the regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer will be significantly more than costs we incur as a foreign private issuer.

U.S. investors may not be able to enforce their civil liabilities against our Company or certain of our directors, controlling persons and officers.

It may be difficult for U.S. investors to bring and/or effectively enforce suits against our Company outside of the United States. We are a public limited company incorporated in England and Wales under the Companies Act 2006, as amended, or the Companies Act. A majority of our directors are not residents of the United States, and all or substantial portions of their assets are located outside of the United States. As a result, it may be difficult for U.S. holders of our ordinary shares or ADSs to effect service of process on these persons within the United States or to make effective recovery in the United States by enforcing any judgments rendered against them. In addition, if a judgment is obtained in the U.S. courts based on civil liability provisions of the U.S. federal securities laws against us or our directors or officers, it may, depending on the jurisdiction, be difficult to enforce the judgment in the non-U.S. courts against us and any of our non-U.S. resident executive officers or directors. Accordingly, U.S. shareholders may be forced to bring legal proceedings against us and our respective directors and officers under English law and in the English courts in order to enforce any claims that they may have against us or our directors and officers. The enforceability of a U.S. judgment in the United Kingdom will depend on the particular facts of the case as well as the laws and treaties in effect at the time. The United States and the United Kingdom do not currently have a treaty providing for reciprocal recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters. Nevertheless, it may be difficult for U.S. shareholders to bring an original action in the English courts to enforce liabilities based on the U.S. federal securities laws against us and any of our non-U.S. resident executive officers or directors.

The rights of our shareholders may differ from the rights typically offered to shareholders of a U.S. corporation.

We are incorporated under English law. The rights of holders of ordinary shares and, therefore, certain of the rights of holders of ADSs, are governed by English law, including the provisions of the Companies Act, and by our Articles of Association. These rights differ in certain respects from the rights of shareholders in typical U.S. corporations.

Provisions in the UK City Code on Takeovers and Mergers may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our shareholders.

The UK City Code on Takeovers and Mergers, or the Takeover Code, applies, among other things, to an offer for a public company whose registered office is in the United Kingdom and whose securities are not admitted to trading on a regulated market in the United Kingdom if the company is considered by the Panel on Takeovers and Mergers, or the Takeover Panel, to have its place of central management and control in the United Kingdom. This is known as the “residency test.” The test for central management and control under the Takeover Code is different from that used by the UK tax authorities. Under the Takeover Code, the Takeover Panel will determine whether we have our place of central management and control in the United Kingdom by looking at various factors, including the structure of our board of directors, the functions of the directors and where they are resident. Whilst the Takeover Panel has not informed us of any such determination, on account of the current constitution of our board, we believe that we are currently subject to the Takeover Code.

Table of Contents

If at the time of a takeover offer the Takeover Panel determines that we have our place of central management and control in the United Kingdom, we will be subject to a number of rules and restrictions, including but not limited to the following: (1) our ability to enter into deal protection arrangements with a bidder will be extremely limited; (2) we may not, without the approval of our shareholders, be able to perform certain actions that could have the effect of frustrating an offer, such as issuing shares or carrying out acquisitions or disposals; and (3) we will be obliged to provide equality of information to all bona fide competing bidders.

Further, the Takeover Code contains certain rules in respect of mandatory offers. Under Rule 9 of the Takeover Code, if a person: (a) acquires an interest in our shares which, when taken together with shares in which he or persons acting in concert with him are interested, carry 30% or more of our voting rights; or (b) who, together with persons acting in concert with him, is interested in shares that in the aggregate carry not less than 30% of our voting rights and does not hold shares carrying more than 50% of our voting rights, acquires additional interests in shares that increase the percentage of shares carrying voting rights in which that person is interested, the acquirer and, depending on the circumstances, its concert parties, will be required (except with the consent of the Takeover Panel) to make a cash offer for our outstanding shares at a price not less than the highest price paid for any interest in our shares by the acquirer or its concert parties during the previous 12 months.

Holders of ADSs must act through the depositary to exercise their rights as shareholders of our Company.

Holders of our ADSs do not have the same rights of our shareholders and may only exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement for the ADSs. Under our Articles of Association, the minimum notice period required to convene a general meeting is 14 clear days’ notice (or, for an annual general meeting, 21 clear days’ notice (unless, in the case of an annual general meeting, all members entitled to attend and vote at the meeting, or, in the case of any other general meeting, a majority in number of the members entitled to attend and vote who hold not less than 95% of the voting shares (excluding treasury shares), agree to shorter notice). When a general meeting is convened, holders of our ADSs may not receive sufficient notice of a shareholders’ meeting to permit them to withdraw their ordinary shares to allow them to cast their vote with respect to any specific matter. In addition, the depositary and its agents may not be able to send voting instructions to holders of our ADSs or carry out their voting instructions in a timely manner. We will make all reasonable efforts to cause the depositary to extend voting rights to holders of our ADSs in a timely manner, but we cannot assure them that they will receive the voting materials in time to ensure that they can instruct the depositary to vote their ADSs. Furthermore, the depositary and its agents will not be responsible for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a result, holders of our ADSs may not be able to exercise their right to vote and they may lack recourse if their ADSs are not voted as they requested. In addition, in the capacity as an ADS holder, they will not be able to call a shareholders’ meeting.

Holders of our ADSs may be subject to limitations on transfers of ADSs.

ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

The rights of holders of our ADSs to participate in any future rights offerings may be limited, which may cause dilution to their holdings and they may not receive cash dividends if it is impractical to make them available to them.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to holders of our ADSs in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary will not make rights available to holders of our ADSs unless either both the rights and any related securities are registered under the Securities Act, or the distribution of them to ADS holders is exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, holders of our ADSs may be unable to participate in our rights offerings and may experience dilution in their holdings.

In addition, the depositary has agreed to pay to holders of our ADSs the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. Holders of our ADSs will receive

37

these distributions in proportion to the number of ordinary shares their ADSs represent. However, the depositary may, at its discretion, decide that it is inequitable or impractical to make a distribution available to any holders of ADSs. For example, the depositary may determine that it is not practicable to distribute certain property through the mail, or that the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may decide not to distribute such property and holders of our ADSs will not receive any such distribution.

We are a clinical-stage biopharmaceutical company focused on developing advanced therapies for autoimmune and inflammatory diseases, specifically through the inhibition of the complement and leukotriene pathways. Each of these systems has scientifically well-supported causative roles in the diseases we are targeting. We believe that blocking early mediators of inflammation will prevent initiation and continual amplification of the processes that cause certain diseases.

Our lead product candidate, nomacopan, inhibits both terminal complement activation and leukotriene B4, or LTB4. It inhibits terminal complement activation by tightly binding to C5 and preventing its cleavage. It inhibits LTB4 by capturing the fatty acid within the body of the nomacopan protein.

Nomacopan is a recombinant small protein (16,769 Da) derived from a protein originally discovered in the saliva of the Ornithodoros moubata tick, where it modulates the host immune system to allow the parasite to feed without alerting the host to its presence or provoking an immune response.

Nomacopan has received orphan drug designation from the U.S. Food and Drug Administration, or the FDA, and the European Medicines Agency, or the EMA, for PNH, GBS, HSCT-TMA, and BP. Orphan drug designation provides us with certain benefits and incentives, including a period of marketing exclusivity if marketing authorization of the drug is ultimately received for the designated indication. The receipt of orphan drug designation status does not change the regulatory requirements or process for obtaining marketing approval and the designation does not mean that marketing approval will be received.

We have received Fast Track designation from the FDA for the investigation of nomacopan for the treatment of pediatric HSCT-TMA and for the treatment of PNH in patients who have polymorphisms conferring Soliris® (eculizumab) resistance and the treatment of BP. The Fast Track program was created by the FDA to facilitate the development and expedite the review of new drugs which show promise in treating a serious or life-threatening disease and address an unmet medical need. Drugs with Fast Track designation may also qualify for priority review to expedite the FDA review process, if relevant criteria are met.

Our clinical targets for nomacopan are orphan inflammatory diseases where the inhibition of both C5 and LTB4 are implicated, including BP, pediatric HSCT-TMA, and as well as both orphan and mass market inflammatory conditions in the eye and lung.

Clinical Development Programs — Past and Current

Phase Ia Single Ascending Dose Trial

Nomacopan entered clinical development in 2013 when a Phase Ia clinical trial was initiated under a Clinical Trials Authorization (CTA) issued by the Medicines and Healthcare products Regulatory Agency (MHRA), an executive agency of the Department of Health and Social Care in the United Kingdom. The primary objective of this single ascending dose, first-in-man study was to explore the safety profile of nomacopan in 24 subjects. The drug was well tolerated, and no serious or dose-related serious adverse events were reported. The secondary objective of this Phase Ia clinical trial was to examine the effect of nomacopan on complement activity at the highest, therapeutic dose. This showed that the peak onset of action was about nine hours after injection, and that the effect of a single dose was detectable for more than 96 hours. The effects were consistent between all subjects and showed 100% inhibition of the complement system within 12 hours.

Phase Ib Dose Range Finding Trial

A Phase Ib repeat dose study was initiated in the first quarter of 2016. In this double-blind, randomized Phase Ib trial, each cohort of six normal healthy volunteers was given either a loading dose of subcutaneous placebo twice a day for two days followed by five days of a single daily placebo dose (n=2) or a loading dose of 30 mg of subcutaneous nomacopan twice a day for two days followed by five days of a single daily subcutaneous maintenance dose (n=4) of either 15 mg, 22.5 mg or 30 mg.

Data from the 22.5 mg once daily maintenance cohort and 30 mg once daily maintenance cohort demonstrated that subcutaneous nomacopan achieved complete complement inhibition (Elisa CH50 < 8 Eq/ml, lower limit of quantification) within the first day, and demonstrated complete complement inhibition at the end of dosing on day seven whether measured using the ELISA or lytic CH50 assays.

Table of Contents

The data from the 15 mg once daily maintenance cohort demonstrated that subcutaneous nomacopan achieved complete complement inhibition (Elisa CH50 < 8 Eq/ml, lower limit of quantification) within the first day following an ablating dose but by day three was unable to maintain complete complement inhibition at the 24-hour trough measurement. A final cohort of 4 healthy volunteers was given 22.5 mg of nomacopan as a maintenance dose for 21 days. Complete complement inhibition was demonstrated at the end of the 21 day period of once daily dosing and there were no neutralizing antibodies detected. One volunteer receiving the nomacopan in the 30 mg 7 day cohort stopped dosing on day three due to a non-serious adverse event possibly related to antibiotics administered for meningitis prophylaxis. The trial was conducted at Hammersmith Medicines Research Ltd, in London.

BP Clinical Program

We continue to develop nomacopan in a number of indications, including ones that take advantage of the dual-acting properties of the drug to inhibit both C5 and LTB4. In patients with BP there is evidence that both C5 and LTB4 have a central role in driving the disease. Ex vivo data, from a study at Lubeck University, in BP patients showed a pronounced accumulation of LTB4 and C5 and its activation products in the inflamed skin of bullous pemphigoid disease patients.

In 2018, we opened our first site for a six-week Phase IIa open label, single-arm trial to evaluate the safety and efficacy of nomacopan in patients with mild to moderate BP. Patients entering the trial were typically on the topical steroid mometasone which was stopped by day 21. The primary endpoints of the trial were a proportion of patients reporting grade 3, 4 and 5 adverse events which are related/possibly related to nomacopan during the treatment period and secondary and other endpoints include, among others, Bullous Pemphigoid Disease Area Index (BPDAI) score.

In May 2020, we announced positive topline results from our fully recruited Phase II study of nomacopan in BP patients. The study achieved no drug-related serious adverse events with seven of nine treated patients showing a rapid and clinically significant reduction in BPDAI score. Of the seven responders, three showed an 80%+ reduction in BPDAI score and three an approximately 40% reduction in BPDAI score within six weeks of starting nomacopan. Results from the Phase II study of nomacopan in BP were published in in JAMA-Dermatology in May 2022.

We initiated a pivotal Phase III program for the treatment of BP in 2021 following the opening of an IND with the FDA and have opened the first sites for our study of nomacopan for the treatment of BP. Supply chain issues resulted in delays in the study; however, in May 2022, some sites started recruiting. Following positive FDA and EMA meetings in 2020, the pivotal trial design is in two parts, with Part A and Part B having the same structure, duration, endpoints and target population of moderate and severe BP patients.

HSCT-TMA Clinical Program

HSCT-TMA is an orphan condition with an estimated fatality rate of more than 80% in pediatric patients with the disease. A framework for a pivotal trial design for pediatric patients was agreed with the FDA in which the response to nomacopan of selected, clinically meaningful treatment variables would be the primary endpoint. In September 2018, Akari announced that in the first two patients treated with nomacopan as part of a UK named patient program it had observed a rapid reduction of the markers of complement activation as well as normalization of markers that are elevated in HSCT-TMA (platelet count, red blood cell fragments, thrombocytopenia, elevated LDH and hypertension).

In December 2019, we opened a multi-center Phase III study for the treatment of pediatric HSCT-TMA with nomacopan. The primary endpoints are focused on disease response defined primarily by renal improvement and reduced transfusion dependence. This two-part pivotal Phase III study of nomacopan in pediatric patients with HSCT-TMA is based on guidance from our end-of-Phase II meeting with the FDA. Part A of the trial is a dose confirmation study. Part B of the trial is a single arm responder-based efficacy study that will follow an interim analysis of Part A and a meeting with the FDA. As a result of the COVID-19 outbreak, we experienced delays in openings and enrollment. However, Part A of the trial in pediatric HSCT-TMA is now enrolling in Europe and the U.S. subject to the ongoing impact of COVID-19 related restrictions. We have dosed the first patients in connection with Part A of the trial.

Front And Back Of The Eye Programs

Results in a rodent model of Experimental Immune Conjunctivitis (EIC), undertaken at Moorfields Hospital Institute of Ophthalmology, showed that nomacopan demonstrated significant anti-inflammatory activity. In this preclinical model of severe eye

surface inflammation, nomacopan, applied topically, resulted in a statistically significant reduction (64%, p<0.001) in late phase inflammation versus placebo.

During the third quarter of 2018, we commenced a Phase I/II randomized, double blinded, placebo-controlled trial with an initial three patients (Part A) prior to the blinding (Part B) to evaluate the safety and efficacy of nomacopan in patients with the inflammatory mediated eye disorder AKC. In Part A of the Phase I/II study, three patients were treated with twice daily nomacopan eye drops in addition to standard of care for up to 56 days in order to establish the safety and tolerability of the drops in preparation for Part B, a randomized, double-masked placebo-controlled comparison in 16 patients. The drops were found to be comfortable and well-tolerated throughout the trial for all three patients. There were no serious adverse events reported. On that basis, the independent safety committee gave permission for the trial to proceed to Part B. Enrollment in the Part B placebo-controlled efficacy arm of the study was halted in H1 2020 due to the COVID-19 outbreak. Of the 12 patients recruited, a complete data set was available on 10 patients – two from Part A and eight from Part B. In Part B, of the eight patients recruited, six were placebo (four AKC patients and two other surface of the eye diagnosis) and two were treated with nomacopan (two AKC patients). As a first-in-eye Phase I/II study, the primary endpoint measure was safety. Aggregating data from the eight AKC patients from Part A and Part B shows no ocular treatment emergent serious adverse events during the eight-week treatment period. Nomacopan is delivered topically without preservatives and is pH neutral. A comfort score measured after each eye drop installation showed the drug was comfortable and well tolerated. Although the four nomacopan treated AKC patients achieved a higher improved mean efficacy score than the four placebo AKC patients, the patient numbers are too small to show statistical significance on efficacy measures between the two treatment groups.

During 2020 and 2021, the Company announced preclinical data comparing the therapeutic efficacy of nomacopan, long acting PAS-nomacopan, and a monoclonal anti-VEGF antibody all administered intravitreally. PAS-nomacopan was found to reduce intraocular VEGF levels by as much as the anti-VEGF antibody with 74% (p=0.04) and 68% (p=0.05) reductions respectively, compared to saline control. Furthermore, based on a clinical score measurement, inflammation increased in both the control and anti-VEGF groups by 49% and 33%, respectively, PAS-nomacopan treatment showed a 9% reduction in inflammation assessed by retinal fundoscopy (p=0.02). This therapeutic activity across multiple pathogenic pathways (VEGF, inflammation and complement) supports the potential for nomacopan as a new mode of action for the treatment of back of the eye diseases.

During the fourth quarter of 2020, the Company announced the publication of the results of a two-year research collaboration with the UCL Institute of Ophthalmology. The results showed that the therapeutic intravitreal (IVT) administration of long-acting PAS-nomacopan mitigated both the severity and progress of retinal damage in two models of autoimmune uveitis, a severe inflammatory eye disease where steroids are the primary treatment option. In addition, results showed the presence of inflammatory cells expressing both complement C5 and LTB4 receptors in retinal tissue from donor patients with uveitis as compared to healthy donor eyes. We are currently undertaking additional pre-clinical studies as part of a program to explore the potential for PAS-nomacopan as a treatment for Geographic Atrophy / Dry AMD.

During the second quarter of 2022, the Company announced positive results from two preclinical studies of investigational nomacopan in diseases of the eye. The preclinical results confirm bioavailability of PAS-nomacopan in the retina and suggest that a clinical dose interval of three months or more may be possible. Studies have shown that due to adverse effects, such as an increase in intraocular pressure and discomfort and anxiety, intravitreal, or IVT, injection of PAS-nomacopan presents a heavy burden on patients. Our preclinical results show that PAS-nomacopan has the potential to make IVT injection long-lasting in the back of the eye and may provide a three-month dosing interval that is less burdensome and thus more attractive for patients.

Pulmonary Program

We are in the early stages of exploring opportunities in inflammatory lung diseases with severe exacerbations where complement and leukotriene pathways are implicated.

PNH Clinical Program

The PNH program consists of four separate studies.

Phase II PNH Eculizumab-Resistant Trials which opened in Q1 2016 and has treated two patients and is now closed.

Phase II COBALT PNH Trial which opened in Q4 2016 and has treated eight patients and is now closed.

41

Table of Contents

Phase III CAPSTONE PNH Trial which opened in Q1 2018 and has treated nine patients and is now closed.

Long-Term Safety and Efficacy CONSERVE Study which treated 15 patients and is now closed.

In December 2020, we announced new data on the efficacy and safety profile of long-term self-administration of nomacopan for treatment of patients with PNH.

The data from 19 PNH patients treated for a median of 18.5 months are derived from the Phase II COBALT trial (n=8 patients), the Phase II trial which specifically recruited eculizumab-resistant patients (n=2 patients), the Phase III CAPSTONE trial (n = 9 patients), and from the long-term safety study CONSERVE (n = 15), which accepted patients from the Phase II and Phase III studies. Sixteen of the 19 PNH patients were transfusion dependent prior to treatment with nomacopan, of whom 14 were treated with nomacopan for six months or more.

The data show that long term self-administration of nomacopan by PNH patients:

Immunogenicity

A chronic (28 day) dosing experiment in mice investigated whether daily subcutaneous administration of the expected therapeutic dose of nomacopan induces an antibody response, and whether the antibodies neutralize complement inhibition by nomacopan. The data from this chronic dosing experiment showed nomacopan was well-tolerated with no injection site allergic reactions or behavioral changes. Nomacopan can induce formation of low titre anti-drug IgG antibodies in mice after four weeks of daily inoculation, which is not uncommon, but these antibodies were not neutralizing and had no effect on nomacopan’s ability to inhibit complement.

No neutralizing antibodies have been detected, including in the healthy volunteers in the Phase Ia and Ib trials, and the PNH studies.

PAS Nomacopan

Using PASylation®, a proprietary process of XL-protein GmbH, XL-protein has modified nomacopan by adding a 600 amino acid proline/alanine/ serine (PAS) N-terminal fusion tag to generate PAS-nomacopan (68kDa). The unstructured and uncharged PAS polypeptide increases the apparent molecular size to approximately 700kDa, slowing kidney clearance and extending the half-life.

Data from mouse, rat and dog studies of PAS-nomacopan demonstrated that the expected terminal half-life in humans could be approximately 4 days. Based on these data, PK modeling supports that a once weekly dosing regimen may be feasible. In addition work in a rabbit eye model has demonstrated the potential for intravitreal dosing once as long as every three months using PAS-nomacopan.

In addition, new data in a porcine model has shown a similar PK profile for the higher concentrated formulation to be used across our subcutaneous programs. This new highly concentrated formulation with small (0.3mL) volume and water-like viscosity is intended to allow ease of administration and increased patient comfort.

Target Indications

Bullous Pemphigoid

BP is an autoimmune blistering skin disease. BP is a serious condition with significant associated morbidity and mortality. Widespread tense and hemorrhagic blisters, skin erosions and severe itching cause patients a great deal of distress and pain.

Untreated, BP may be a self-limiting disease in a proportion of patients with periods of spontaneous remissions and exacerbations. In most patients who are treated, BP remits within 1.5-5 years but may recur once medication is stopped. Patients are often admitted to hospital for initial treatment. The estimates of admission rates for patients with BP vary, but they are generally high, thus representing a significant burden and cost to the healthcare systems, as well to the patients’ and their families/careers. The severity of symptoms and lesions in BP make treatment mandatory. Corticosteroids are often administered and frequent hospital visits are needed for dose adjustments.

Older age at onset and frail general condition are poor prognostic factors. Many available treatments are associated with toxicity and may be poorly tolerated in patients with BP. It is thought that, in the elderly population, corticosteroid treatment contributes to the high mortality rate. This is due, at least in part, to the significant adverse events associated with the use of steroids, such as hypertension, diabetes, infections and osteoporosis. Management of these conditions can be difficult, and their treatment represents a significant burden. Therefore, the avoidance of systemic corticosteroids in this vulnerable group of patients is highly desirable and a safer, effective, evidence-based alternative is needed.

Treatment should aim to control symptoms with minimum adverse effects where possible. Options are broadly divided into anti-inflammatory drugs, immunosuppressive or immunomodulating drugs, and procedures that aim to remove circulating pathogenic antibodies and inflammatory mediators. Corticosteroids are the most commonly used anti-inflammatory drugs given for treatment of BP. They are administered systemically, for example prednisolone, or topically for very potent steroids such as clobetasol. Anti-inflammatory antibiotics such as tetracyclines are used as well. Long-term use of potent steroids is associated with a threefold increase in mortality and several adverse effects such as severe skin atrophy, osteoporosis, diabetes, glaucoma, cataract formation, weight gain, and psychologic disturbances. Intravenous immunoglobulins have been used as immunomodulatory agents in BP as well as other auto immune blistering skin diseases.

The choice of treatment depends on the individual patient’s circumstances especially the severity of the BP and presence of comorbidities. All of these treatment options have limited applicability due to reasons associated with efficacy, safety or both. And thus, there exists a need for a safe and effective therapy for BP patients.

Hemopoietic Stem Cell Transplant - Thrombotic Microangiopathy (HSCT-TMA)

TMAs are a group of diseases in which thrombosis occurs in small blood vessels as a result of damage to the endothelium (lining) of the vessels. This leads to hemolytic anaemia, low platelet count (thrombocytopenia), end organ damage which may result in complications including renal failure, stroke and pulmonary hypertension. The major varieties of TMA are hemolytic uremic syndrome

43

Table of Contents

(HUS), atypical hemolytic uremic syndrome (aHUS), thrombotic thrombocytopenic purpura (TTP), antiphospholipid syndrome (APS), disseminated intravascular coagulation (DIC), malignant hypertension, scleroderma renal failure and TMA associated with hemopoietic stem cell transplant (HSCT). The latter is often linked to toxicity of calcineurin inhibitors which are used to protect against graft versus host disease (GvHD). There are no currently approved drugs for the treatment of HSCT-TMA and, untreated, the condition in its more severe forms has a high risk of death.

Other Indications

We are also conducting research, or have conducted research, into the use of nomacopan for the treatment of other diseases in the lung, front and back of the eye. These are all larger diseases with a high unmet need where initial data supports the potential clinical benefit of inhibiting complement C5 and leukotriene LTB4 with either nomacopan or PAS-nomacopan.

Market Opportunity in Complement Mediated Diseases

The NIH estimates that approximately 23.5 million Americans may suffer from an autoimmune disorder, although this number is almost certainly an underestimate of the actual prevalence as it includes only 24 diseases for which good epidemiology studies were available. It is estimated that an additional 1.18 million people in the US will acquire/develop an autoimmune disease every five years.  Women are 2.7 times more likely than men to develop an autoimmune disease. Researchers have identified 80 – 100 different autoimmune diseases and suspect at least 40 additional diseases of having an autoimmune basis. Patients with one autoimmune disease are at increased risk of other diseases with an autoimmune basis. These diseases are chronic and can be life-threatening. Autoimmune disease is one of the top 10 leading causes of death in female children and women in all age groups up to 64 years of age. The NIH estimates annual direct health care costs for autoimmune diseases to be in the range of $100 billion.

Both the complement and leukotriene pathways work as part of the immune system to disable and clear out foreign invaders and unwanted cells, and as such, plays an important role in the pathology of many autoimmune diseases. The term “Complement Mediated Diseases” applies to diseases and conditions where a patient’s immune system attacks and destroys healthy body tissue by mistake, causing damage through its complement component and through mediators induced by complement activation. These diseases and conditions are often rare, and include such diseases as PNH, aHUS, GBS, Myasthenia Gravis, HSCT-TMA, transplant mediated organ rejection, glomerulopathies (kidney diseases), as well as numerous other disorders. While not all complement mediated diseases will respond to a direct C5 inhibitor, like nomacopan, there is a meaningful potential market opportunity as demonstrated by

In addition to those conditions listed, where complement activity is believed to be the primary driver of disease, there are many other poorly treated diseases where in addition to complement activation other inflammatory pathways are implicated. Examples of such diseases where both the complement and leukotriene pathways are both believed to play an active role include BP, AKC, vasculitis, trauma and several severe inflammatory lung conditions.

Competition in Complement and Leukotriene Mediated Diseases

The development and commercialization of new drugs is highly competitive. We will face competition with respect to all product candidates that we may develop or commercialize in the future from pharmaceutical and biotechnology companies worldwide. The key factors affecting the success of any approved product will be its efficacy, safety profile, drug interactions, method of administration, pricing, reimbursement and level of promotional activity relative to those of competing drugs.

Our potential competitors may have substantially greater financial, technical, and personnel resources than we do. In addition, many of these competitors have significantly greater commercial infrastructures. Our ability to compete successfully will depend largely on our ability to leverage our collective experience in drug discovery, development and commercialization to:

Table of Contents

There has been a broad research effort in complement-based therapy to date, with eculizumab being the first therapy approved that directly inhibits C5. Although there is currently less research and development effort in the leukotriene field there are approved leukotriene inhibitors used as a treatment for severe asthma. However, we are aware of certain other companies and academic institutions that are continuing their efforts to discover and develop alternate complement and/or C5 inhibitors, including Alexion Pharmaceuticals, a subsidiary of AstraZeneca, Apellis, Omeros, Chemocentryx, and UCB.

Sales and Marketing

Because we have been focused on discovery and development of drugs, we currently have limited sales, marketing and distribution capabilities in order to commercialize nomacopan or any approved product candidates. If our lead product candidate nomacopan is approved, we intend either to establish a sales and marketing organization with technical expertise and supporting distribution capabilities to commercialize nomacopan, or to outsource some or all of this function to third parties. We may take different approaches to commercialization in different geographies.  We will adopt a similar strategy for the other compounds in our pipeline.

Manufacturing

We currently employ third-party contract manufacturers, or CDMOs, which manufacture in accordance with current good manufacturing practice requirements, for investigational medical products, including active pharmaceutical ingredients, drug substance and drug products for our preclinical research and clinical studies for nomacopan. Analytical methods have been established and qualified for release testing of drug substance and drug products. We have successfully manufactured nomacopan drug substance and drug product batches in 2016 and manufactured multiple lots of nomacopan in 2018, 2019, 2020, 2021 and year to date 2022.

We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We currently rely, and expect to continue to rely, on CMOs for the manufacture of nomacopan and any other product candidates that we may develop for larger scale preclinical and clinical testing, as well as for commercial quantities of any product candidates that are approved.

In January 2021, we announced that the FDA has agreed, via a Type C meeting, to the clinical use of nomacopan derived from a next generation manufacturing process. This process increases the final yield of nomacopan at least 5-fold, compared to the previous manufacturing process, which may significantly decrease future commercial cost of goods and reduce the cost of ongoing Phase II/III and future clinical development programs for nomacopan.

We have experienced delays in patient recruitment in BP due to supply chain issues with a third party supplier. In May 2022, we received a final report regarding the matter. As of the date of this Annual Report on Form 20-F, we have resolved such issues, and we do not anticipate further delays at this time.

As a result, we may encounter disruptions in the supply chain of nomacopan which could negatively impact our ability to supply our drug product to clinical trial sites, delaying clinical studies.

Intellectual Property

We will be able to protect our technology and products from unauthorized use by third parties only to the extent it is covered by valid and enforceable patents or is effectively maintained as trade secrets. Patents and other proprietary rights are thus an essential element of our business.

Our success will depend in part on our ability to obtain and maintain proprietary protection for our product candidates, technology, and know-how, to operate without infringing on the proprietary rights of others, and to prevent others from infringing our proprietary rights. Our policy is to seek to protect our proprietary position by, among other methods, filing U.S. and foreign patent applications related to our proprietary technology, inventions, and improvements that are important to the development of our business and defending our patent applications and patents if they are subjected to challenge by a third party. We also rely on trade secrets, know-how, continuing technological innovation, and in-licensing opportunities to develop and maintain our proprietary position.

Table of Contents

We own or have exclusive rights to patents and patent applications based on 15 international patent applications. This includes eight United States patents, eight patents granted by the European Patent Office and foreign issued patents in other jurisdictions. This further includes pending patent applications in the United States and other jurisdictions. Our patents and patent applications relate to the complement C5 inhibitor protein nomacopan and to its use in the treatment of key disease indications, as well as to nomacopan variants, and histamine binding proteins. Our current patent portfolio includes granted patents in the jurisdictions of United States, Canada, major European countries, Japan, China, Brazil, Israel, Hong Kong, Mexico, Russia, Australia, New Zealand and pending applications in the jurisdictions of United States, Canada, Europe, Japan, China, Brazil, Israel, Republic of Korea, Australia and New Zealand.

Issued patents in the US and other countries which cover our product candidate nomacopan and its uses will expire between 2024 and 2035, excluding any patent term extensions that might be available following the grant of marketing authorizations. We have pending patent applications for our product candidate nomacopan and its uses that, if issued, would expire in the United States and in countries outside of the United States between 2024 and 2040, excluding any patent term adjustment that might be available following the grant of the patent and any patent term extensions that might be available following the grant of marketing authorizations. These patent and patent applications relate to subject matters including: complement inhibitor molecule; methods for treating myasthenia gravis; methods for treating peripheral nerve disorders; methods for treating respiratory disorders; methods for treating viral infections of the respiratory tract; methods of treating complement-mediated diseases in patients with C5 polymorphisms, methods of treating acute graft versus host disease; methods of treating cicatrizing eye inflammatory disorders; methods of treating autoimmune blistering diseases; methods of treating rheumatic diseases; methods of treating proliferative retinal diseases; methods of treating HSCT-TMA, and nomacopan variants lacking C5 or LTB4 binding. If we are unable to obtain, maintain, defend and enforce patent and other intellectual property rights for our technologies and product candidate nomacopan, or if the scope of the patent and other intellectual property rights obtained is not sufficiently broad, our competitors and other third parties could develop and commercialize technology, biologics and/or biosimilars similar or identical to ours, and erode or negate any competitive advantage that we may have, which could harm our business and ability to achieve profitability.

We can provide no assurance that our patent applications or those of our licensors will result in additional patents being issued or that issued patents will afford sufficient protection against competitors with similar technologies, nor can there be any assurance that the patents issued will not be infringed, designed around or invalidated by third parties. Even issued patents may later be found unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. The degree of future protection for our proprietary rights is uncertain. Only limited protection may be available and may not adequately protect our rights or permit us to gain or keep competitive advantage. Composition-of-matter patents on the biological or chemical active pharmaceutical ingredients are generally considered to offer the strongest protection of intellectual property and provide the broadest scope of patent protection for pharmaceutical products, as such patents provide protection without regard to any method of use or any method of manufacturing. While we have issued composition-of-matter patents in the United States and other countries for nomacopan, we cannot be certain that the claims in our issued composition-of-matter patents will not be found invalid or unenforceable if challenged. We cannot be certain that the claims in any patent applications covering composition-of-matter or formulations of our product candidates that are pending, or that we may file, will be considered patentable by the United States Patent and Trademark Office, or USPTO, and courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that the claims in our issued composition-of-matter patents will not be found invalid or unenforceable if challenged. Even if any patent applications that we may file relating to specific formulations of our product candidates issue as patents, formulation patents protect a specific formulation of a product and may not be enforced against competitors making and marketing a product that has the same active pharmaceutical ingredient in a different formulation. Method-of-use patents protect the use of a product for the specified method or for treatment of a particular indication. This type of patent may not be enforced against competitors making and marketing a product that has the same active pharmaceutical ingredient for use in a method not claimed by the patent. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products “off-label.” Although off-label prescriptions may infringe or contribute to the infringement of method-of-use patents, the practice is common and such infringement may be difficult to prevent or prosecute. Also, as is the case for composition-of-matter patents, we cannot be certain that the claims in our issued method-of-use patents will not be found invalid or unenforceable if challenged. We cannot be certain that the claims in any patent applications covering methods of using our product candidates that are pending, or that we may file, will be considered patentable by the United States Patent and Trademark Office, or USPTO, and courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that the claims in our issued method-of-use patents will not be found invalid or unenforceable if challenged.

Government Regulation

Government Regulation and Product Approval

Government authorities in the U.S., at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, marketing and export and import of products such as those that we are developing. A new drug must be approved by the FDA, generally through the new drug application, or NDA, process and a new biologic must be approved by the FDA through the biologics license application, or BLA, process before it may be legally marketed in the U.S. The animal and other non-clinical data and the results of human clinical trials performed under an Investigational New Drug application, or IND, and under similar foreign applications will become part of the NDA or BLA.

U.S. Drug Development Process

In the U.S., the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and in the case of biologics, also under the Public Health Service Act, or PHSA, and implementing regulations. The process of obtaining marketing authorizations and the subsequent compliance with applicable federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, requesting product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. The process required by the FDA before a drug or biologic may be marketed in the U.S. generally involves the following:

Once a pharmaceutical candidate is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies. An IND sponsor must submit the results of the preclinical tests, together with manufacturing information and analytical data, to the FDA as part of the IND. The sponsor will also include a protocol detailing, among other things, the objectives of the first phase of the clinical trials, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated, if the first phase lends itself to an efficacy evaluation. Some preclinical testing may continue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Clinical holds also may be imposed by the FDA at any time before or during studies due to safety concerns or non-compliance.

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with good clinical practice regulations. They must be conducted under protocols detailing the objectives of the trial, dosing procedures, subject

47

Table of Contents

selection and exclusion criteria and the safety and effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND, and progress reports detailing the results of the clinical trials must be submitted at least annually. In addition, timely safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events. An institutional review board, or IRB, responsible for the research conducted at each institution participating in the clinical trial must review and approve each protocol before a clinical trial commences at that institution and must also approve the information regarding the trial and the consent form that must be provided to each trial subject or his or her legal representative, monitor the study until completed and otherwise comply with IRB regulations.

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

The FDA or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. Phase I, Phase II, and Phase III testing may not be completed successfully within any specified period, if at all.

During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to submission of an IND, at the end of Phase II, and before an NDA or BLA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the data gathered to date, for the FDA to provide advice, and for the sponsor and FDA to reach agreement on the next phase of development. Sponsors typically use the end of Phase II meeting to discuss their Phase II clinical results and present their plans for the pivotal Phase III clinical trial that they believe will support approval of the new drug.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA. Safety reports must be submitted to the FDA and the investigators 15 calendar days after the trial sponsor determines that the information qualifies for reporting. The sponsor also must notify FDA of any unexpected fatal or life-threatening suspected adverse reaction as soon as possible but in no case later than 7 calendar days after the sponsor’s initial receipt of the information. Sponsors of clinical trials of FDA-regulated products, including drugs, are required to register and disclose certain clinical trial information, which is publicly available at www.clinicaltrials.gov.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final drug. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

U.S. Review and Approval Processes

The results of product development, preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry of the drug, proposed labeling, and other relevant information are submitted to the FDA as

48

Table of Contents

part of an NDA or BLA requesting approval to market the product. The submission of an NDA or BLA is subject to the payment of substantial user fees; a waiver of such fees may be obtained under certain limited circumstances. Within sixty days of receipt, the FDA initially reviews all NDAs and BLAs submitted to ensure that they are sufficiently complete for substantive review before it accepts them for filing. The FDA may request additional information rather than accept a NDA or BLA for filing. In this event, the NDA or BLA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review. FDA may refer the NDA or BLA to an advisory committee for review, evaluation and recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. The approval process is lengthy and often difficult, and the FDA may refuse to approve an NDA or BLA if the applicable regulatory criteria are not satisfied or may require additional clinical or other data and information. Even if such data and information are submitted, the FDA may ultimately decide that the NDA or BLA does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data. The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP-compliant to assure and preserve the product’s identity, strength, quality and purity. The FDA reviews a BLA to determine, among other things whether the product is safe, pure and potent and the facility in which it is manufactured, processed, packed or held meets standards designed to assure the product’s continued safety, purity and potency. Before approving an NDA or BLA, the FDA will inspect the facility or facilities where the product is manufactured. The FDA may issue a complete response letter, which may require additional clinical or other data or impose other conditions that must be met in order to secure final approval of the NDA or BLA, or an approval letter following satisfactory completion of all aspects of the review process. The applicant may either resubmit the NDA or BLA, addressing all of the deficiencies identified in the letter, withdraw the application, or, in the case of an NDA, request an opportunity for a hearing. The applicant also may request resolution of any dispute concerning the CRL. If the FDA denies approval of a BLA, the applicant may request, and FDA must issue, a notice of opportunity for hearing.

NDAs or BLAs may receive either standard or priority review. Under current FDA review goals, standard review of an NDA for a new molecular entity (NME) or original BLA will be ten months from the date that the NDA or BLA is filed. A drug representing a significant improvement in treatment, prevention or diagnosis of disease may receive a priority review of six months. Priority review does not change the standards for approval, but may expedite the approval process.

If a product receives marketing authorization, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. In addition, the FDA may require a sponsor to conduct Phase IV testing which involves clinical trials designed to further assess a drug’s safety and effectiveness after NDA or BLA approval, and may require testing and surveillance programs to monitor the safety of approved products which have been commercialized.

The Food and Drug Administration Safety and Innovation Act, or FDASIA, which was enacted in 2012, made permanent the Pediatric Research Equity Act, or PREA, which requires a sponsor to conduct pediatric studies for most drugs and biologics with a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration. Under PREA, original NDAs, BLAs and supplements thereto, must contain a pediatric assessment unless the sponsor has received a deferral or waiver. The required assessment must assess the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations and support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The sponsor or FDA may request a deferral of pediatric studies for some or all of the pediatric subpopulations. A deferral may be granted for several reasons, including a finding that the drug or biologic is ready for approval for use in adults before pediatric studies are complete or that additional safety or effectiveness data needs to be collected before pediatric studies can begin. After April 2013, the FDA must send a non-compliance letter to any sponsor that fails to submit a required pediatric assessment within specified deadlines or fails to submit a timely request for approval of a pediatric formulation, if required.

Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of FDA approval of our drugs, some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as partial compensation for effective patent term lost due to time spent during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND, and the submission date of an NDA or BLA,

49

Table of Contents

plus the time between the submission date of an NDA or BLA and the approval of that application, except that the period is reduced by any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved drug may be extended, and the extension must be applied for prior to expiration of the patent. The United States Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration.

Pediatric exclusivity is another type of marketing exclusivity available in the U.S. The FDASIA made permanent the Best Pharmaceuticals for Children Act, or BPCA, which provides, under certain circumstances, for an additional six months of marketing exclusivity if a sponsor conducts clinical trials in children in response to a written request from the FDA, or a Written Request. If the Written Request does not include studies in neonates, the FDA is required to include its rationale for not requesting those studies. The FDA may request studies on approved or unapproved indications in separate Written Requests. The issuance of a Written Request does not require the sponsor to undertake the described studies.

Biologics Price Competition and Innovation Act of 2009

The BPCIA amended the PHSA to create an abbreviated approval pathway for two types of “generic” biologics — biosimilars and interchangeable biologic products — and provides for a twelve-year exclusivity period for the first approved biological product, or reference product, against which a biosimilar or interchangeable application is evaluated; however if pediatric studies are performed and accepted by the FDA, the twelve-year exclusivity period will be extended for an additional six months. A biosimilar product is defined as one that is highly similar to a reference product notwithstanding minor differences in clinically inactive components and for which there are no clinically meaningful differences between the biological product and the reference product in terms of the safety, purity and potency of the product. An interchangeable product is a biosimilar product that may be substituted for the reference product without the intervention of the health care provider who prescribed the reference product.

The biosimilar applicant must demonstrate that the product is biosimilar based on data from: (1) analytical studies showing that the biosimilar product is highly similar to the reference product; (2) animal studies (including toxicity); and (3) one or more clinical studies to demonstrate safety, purity and potency in one or more appropriate conditions of use for which the reference product is approved. In addition, the applicant must show that the biosimilar and reference products have the same mechanism of action for the conditions of use on the label, route of administration, dosage and strength, and the production facility must meet standards designed to assure product safety, purity and potency.

An application for a biosimilar product may not be submitted until four years after the date on which the reference product was first approved. The first approved interchangeable biologic product will be granted an exclusivity period of up to one year after it is first commercially marketed, but the exclusivity period may be shortened under certain circumstances.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the U.S., or more than 200,000 individuals in the U.S. and for which there is no reasonable expectation that the cost of developing and making available in the U.S. a drug for this type of disease or condition will be recovered from sales in the U.S. for that drug. Orphan drug designation must be requested before submitting an NDA or BLA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not itself convey any advantage in or shorten the duration of the regulatory review and approval process. If a product that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication, except in very limited circumstances, for seven years. Orphan drug exclusivity, however, also could block the approval of one of our product candidates for seven years if a competitor obtains approval of the same drug, for the same designated orphan indication or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease.

The FDA also administers a clinical research grants program, whereby researchers may compete for funding to conduct clinical trials to support the approval of drugs, biologics, medical devices, and medical foods for rare diseases and conditions. A product does not have to be designated as an orphan drug to be eligible for the grant program. An application for an orphan grant should propose one discrete clinical study to facilitate FDA approval of the product for a rare disease or condition. The study may address an unapproved new product or an unapproved new use for a product already on the market.

Fast Track Designation and Accelerated Approval

The FDA is required to facilitate the development, and expedite the review of, drugs that it finds are intended for the treatment of a serious or life-threatening disease or condition for which there is no effective treatment and which demonstrate the potential to address unmet medical needs for the condition. Under the fast track program, the sponsor of a new product candidate may request that the FDA designate the product candidate for a specific indication as a fast track drug concurrent with, or after, the filing of the IND for the product candidate. The FDA must determine if the product candidate qualifies for fast track designation within 60 days of receipt of the sponsor’s request.

Under the fast track program, the FDA may designate a drug for fast-track status if it is intended to treat a serious or life-threatening illness and nonclinical or clinical data demonstrate the potential to address an unmet medical need. Similarly, the agency may designate a drug for accelerated approval if it treats a serious condition and generally provides meaningful therapeutic benefit to patients over existing treatments based upon a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments.

In clinical trials, a surrogate endpoint is a measurement of laboratory or clinical signs of a disease or condition that substitutes for a direct measurement of how a patient feels, functions, or survives. Surrogate endpoints can often be measured more easily or more rapidly than other clinical endpoints. A product candidate approved on this basis is generally subject to rigorous post-marketing compliance requirements, including the completion of Phase 4 or post-approval clinical trials to confirm the effect on the clinical endpoint. Failure to conduct required post-approval studies, or confirm a clinical benefit during post-marketing studies, will allow the FDA to withdraw the drug from the market on an expedited basis. All promotional materials for product candidates approved under accelerated regulations are subject to prior review by the FDA.

In addition to other benefits such as the ability to use surrogate endpoints and engage in more frequent interactions with the FDA, the FDA may initiate review of sections of a fast track drug’s NDA or BLA before the application is complete. This rolling review is available if the applicant provides, and the FDA approves, a schedule for the submission of the remaining information and the applicant pays applicable user fees. However, the FDA’s time period goal for reviewing an application does not begin until the last section of the application is submitted. Additionally, the fast track designation may be withdrawn by the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

Post-Approval Requirements

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory standards is not maintained or if problems are identified after the product reaches the market. Later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further FDA review and approval. Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws and regulations. We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products. Future inspections by the FDA and other regulatory agencies may identify compliance issues at the facilities of our contract manufacturers that may disrupt production or distribution, or require substantial resources to correct.

Any drug products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the drug, providing the FDA with updated safety and efficacy information, drug sampling and distribution requirements, complying with certain electronic records and signature requirements, and complying with FDA promotion and advertising requirements. The FDA strictly regulates labeling, advertising, promotion and other types of information that may be disseminated about products that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label.

From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the development, approval, manufacturing and marketing of products regulated by the FDA. It is impossible to

51

Table of Contents

predict whether further legislative changes will be enacted, or FDA regulations, guidance or interpretations changed or what the impact of such changes, if any, may be.

Regulation and Marketing Authorization in the European Union

The process governing approval of medicinal products in the European Union follows essentially the same lines as in the United States and, likewise, generally involves satisfactorily completing each of the following:

Preclinical Studies

Preclinical tests include laboratory evaluations of product chemistry, formulation and stability, as well as studies to evaluate toxicity in animal studies, in order to assess the potential safety and efficacy of the product. The conduct of the preclinical tests and formulation of the compounds for testing must comply with the relevant EU regulations and requirements. The results of the preclinical tests, together with relevant manufacturing information and analytical data, are submitted as part of the CTA and MAA.

Clinical Trial Approval

Clinical trials in the European Union are governed by the Clinical Trials Regulation, (EU) No 536/2014, or the CT Regulation. The CT Regulation was adopted in 2014 and replaces the Clinical Trials Directive 2001/20/EC. To ensure that the rules for clinical trials are identical throughout the European Union, the new EU clinical trials legislation was passed as a “regulation” that is directly applicable in all EU member states. All clinical trials performed in the European Union are required to be conducted in accordance with the CT Regulation. Although the CT Regulation entered into force on June 16, 2014 the timing of its application depended on the development of a fully functional Clinical Trial Information System (CTIS), which had to be confirmed by an independent audit. After the process was delayed several times for various reasons, the audit eventually took place in 2021, and the European Commission published the respective notice on July 31, 2021. As a result, the CT Regulation has become applicable on January 31, 2022, with the CTIS going live on the same day.

The New CT Regulation aims to harmonize, simplify and streamline the approval of clinical trials in the European Union. The main characteristics of the CT Regulation include:

52

Table of Contents

Before the CT Regulation became applicable, requirements for the conduct of clinical trials in the EU were regulated by the Clinical Trials Directive 2001/20/EC and the GCP Directive 2005/28/EC. To some extent, these legal frameworks may continue to be applicable under the transitional provisions of the CT Regulation. These transitional provisions allow that where the request for authorization of a clinical trial had been submitted before January 31, 2022 pursuant to the Clinical Trials Directive, that clinical trial shall continue to be governed by the Clinical Trials Directive for three more years, and where the request for authorization of a clinical trial is submitted within 12 months from January 31, 2022, it may be started in accordance with Articles 6, 7 and 9 of the Clinical Trials Directive 2001/20/EC and in that case shall continue to be governed by the Clinical Trials Directive for three more years (i.e. until January 31, 2025).

Marketing Authorization

Authorization to market a product in the member states of the European Union proceeds under one of four procedures: a centralized authorization procedure, a mutual recognition procedure, a decentralized procedure or a national procedure.

Centralized Authorization Procedure

The centralized procedure enables applicants to obtain a marketing authorization that is valid in all EU member states based on a single application. Certain medicinal products, including products developed by means of biotechnological processes, must undergo the centralized authorization procedure for marketing authorization, which, if granted by the European Commission, is automatically valid in all 27 EU member states. The EMA and the European Commission administer this centralized authorization procedure pursuant to Regulation (EC) No 726/2004.

Pursuant to Regulation (EC) No 726/2004, this procedure is mandatory for:

53

Table of Contents

The centralized authorization procedure is optional for other medicinal products if they contain a new active substance or if the applicant shows that the medicinal product concerned constitutes a significant therapeutic, scientific or technical innovation or that the granting of authorization is in the interest of patients in the European Union.

Administrative Procedure

Under the centralized authorization procedure, the EMA’s Committee for Human Medicinal Products, or CHMP, serves as the scientific committee that renders opinions about the safety, efficacy and quality of medicinal products for human use on behalf of the EMA. The CHMP is composed of experts nominated by each member state’s national authority for medicinal products, with expert appointed to act as Rapporteur for the co-ordination of the evaluation with the possible assistance of a further member of the Committee acting as a Co-Rapporteur. After approval, the Rapporteur(s) continue to monitor the product throughout its life cycle. The CHMP has 210 days to adopt an opinion as to whether a marketing authorization should be granted. The process usually takes longer in case additional information is requested, which triggers clock-stops in the procedural timelines. The process is complex and involves extensive consultation with the regulatory authorities of member states and a number of experts. When an application is submitted for a marketing authorization in respect of a drug that is of major interest from the point of view of public health and in particular from the viewpoint of therapeutic innovation, the applicant may pursuant to Article 14(9) Regulation (EC) No 726/2004 request an accelerated assessment procedure. If the CHMP accepts such request, the time-limit of 210 days will be reduced to 150 days but it is possible that the CHMP can revert to the standard time limit for the centralized procedure if it considers that it is no longer appropriate to conduct an accelerated assessment. Once the procedure is completed, a European Public Assessment Report, or EPAR, is produced. If the opinion is negative, information is given as to the grounds on which this conclusion was reached. After the adoption of the CHMP opinion, a decision on the MAA must be adopted by the European Commission, after consulting the EU member states, which in total can take more than 60 days.

Conditional Approval

In specific circumstances, EU legislation (Article 14(7) Regulation (EC) No 726/2004 and Regulation (EC) No 507/2006 on Conditional Marketing Authorizations for Medicinal Products for Human Use) enables applicants to obtain a conditional marketing authorization prior to obtaining the comprehensive clinical data required for an application for a full marketing authorization. Such conditional approvals may be granted for product candidates (including medicines designated as orphan medicinal products) if (1) the risk-benefit balance of the product candidate is positive, (2) it is likely that the applicant will be in a position to provide the required comprehensive clinical trial data, (3) the product fulfills unmet medical needs and (4) the benefit to public health of the immediate availability on the market of the medicinal product concerned outweighs the risk inherent in the fact that additional data are still required. A conditional marketing authorization may contain specific obligations to be fulfilled by the marketing authorization holder, including obligations with respect to the completion of ongoing or new studies, and with respect to the collection of pharmacovigilance data. Conditional marketing authorizations are valid for one year, and may be renewed annually, if the risk-benefit balance remains positive, and after an assessment of the need for additional or modified conditions and/or specific obligations. The timelines for the centralized procedure described above also apply with respect to the review by the CHMP of applications for a conditional marketing authorization.

Marketing Authorization under Exceptional Circumstances

Under Article 14(8) Regulation (EC) No 726/2004, products for which the applicant can demonstrate that comprehensive data (in line with the requirements laid down in Annex I of Directive 2001/83/EC, as amended) cannot be provided (due to specific reasons foreseen in the legislation) might be eligible for marketing authorization under exceptional circumstances. This type of authorization is reviewed annually to reassess the risk-benefit balance. The fulfillment of any specific procedures/obligations imposed as part of the marketing authorization under exceptional circumstances is aimed at the provision of information on the safe and effective use of the product and will normally not lead to the completion of a full dossier/approval.

Enhanced Pathways

Enhanced pathways including a potential rolling review of clinical data by EMA have become more common during the COVID-19 pandemic, but significant requirements have to be met to benefit from such enhanced or facilitated pathways to approval.

Market Authorizations Granted by Authorities of EU Member States

In general, if the centralized procedure is not followed, there are three alternative procedures as prescribed in Directive 2001/83/EC:

A marketing authorization may be granted only to an applicant established in the European Union.

Pediatric Studies

Prior to obtaining a marketing authorization in the European Union, applicants have to demonstrate compliance with all measures included in an EMA-approved Pediatric Investigation Plan, or PIP, covering all subsets of the pediatric population, unless the EMA has granted a product-specific waiver, a class waiver, or a deferral for one or more of the measures included in the PIP. The respective requirements for all marketing authorization procedures are set forth in Regulation (EC) No 1901/2006, which is referred to as the Pediatric Regulation. This requirement also applies when a company wants to add a new indication, pharmaceutical form or route of administration for a medicine that is already authorized. The Pediatric Committee of the EMA, or PDCO, may grant deferrals for some medicines, allowing a company to delay development of the medicine in children until there is enough information to demonstrate its effectiveness and safety in adults. The PDCO may also grant waivers when development of a medicine in children is not needed or is not appropriate, such as for diseases that only affect the elderly population.

Before a marketing authorization application can be filed, or an existing marketing authorization can be amended, the EMA determines that companies actually comply with the agreed studies and measures listed in each relevant PIP.

Periods of Authorization and Renewals

A marketing authorization is valid for five years in principle and the marketing authorization may be renewed after five years on the basis of a re-evaluation of the risk-benefit balance by the competent authority of the authorizing member state. To this end, the marketing authorization holder must provide the EMA or the competent authority with a consolidated version of the file in respect of quality, safety and efficacy, including all variations introduced since the marketing authorization was granted, at least six months before the marketing authorization ceases to be valid. Once renewed, the marketing authorization is valid for an unlimited period, unless the European Commission or the competent authority decides, on justified grounds relating to pharmacovigilance, to proceed with one

additional five-year renewal. Any authorization which is not followed by the actual placing of the drug on the EU market (in case of centralized procedure) or on the market of the authorizing member state within three years after authorization ceases to be valid (the so-called sunset clause).

Orphan Drug Designation and Exclusivity

Pursuant to Regulation (EC) No 141/2000 and Regulation (EC) No. 847/2000, the European Commission can grant such orphan medicinal product designation to products for which the sponsor can establish that it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition affecting not more than five in 10,000 people in the European Union, or a life threatening, seriously debilitating or serious and chronic condition in the European Union and that without incentives it is unlikely that sales of the drug in the European Union would generate a sufficient return to justify the necessary investment. In addition, the sponsor must establish that there is no other satisfactory method approved in the European Union of diagnosing, preventing or treating the condition, or if such a method exists, the proposed orphan drug will be of significant benefit to patients.

Orphan drug designation is not a marketing authorization. It is a designation that provides a number of benefits, including fee reductions, regulatory assistance, and the possibility to apply for a centralized EU marketing authorization, as well as ten years of market exclusivity following a marketing authorization. During this market exclusivity period, neither the EMA, the European Commission nor the member states can accept an application or grant a marketing authorization for a “similar medicinal product.” A “similar medicinal product” is defined as a medicinal product containing a similar active substance or substances as those contained in an authorized orphan medicinal product and that is intended for the same therapeutic indication. The market exclusivity period for the authorized therapeutic indication may be reduced to six years if, at the end of the fifth year, it is established that the orphan designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity. In addition, a competing similar medicinal product may, in limited circumstances, be authorized prior to the expiration of the market exclusivity period, including if it is shown to be safer, more effective or otherwise clinically superior to the already approved orphan drug. Furthermore, a product can lose orphan designation, and the related benefits, prior to obtaining a marketing authorization if it is demonstrated that the orphan designation criteria are no longer met.

Regulatory Data Protection

EU legislation also provides for a system of regulatory data and market exclusivity. According to Article 14(11) of Regulation (EC) No 726/2004, as amended, and Article 10(1) of Directive 2001/83/EC, as amended, upon receiving marketing authorization, new chemical entities approved on the basis of complete independent data package benefit from eight years of data exclusivity and an additional two years of market exclusivity. Data exclusivity prevents regulatory authorities in the European Union from referencing the innovator’s data to assess a generic (abbreviated) application. During the additional two-year period of market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic medicinal product can be marketed until the expiration of the market exclusivity. The overall ten-year period will be extended to a maximum of eleven years if, during the first eight years of those ten years, the marketing authorization holder, or MAH, obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. Even if a compound is considered to be a new chemical entity and the innovator is able to gain the period of data exclusivity, another company nevertheless could also market another version of the drug if such company obtained marketing authorization based on an MAA with a complete independent data package of pharmaceutical tests, preclinical tests and clinical trials. However, products designated as orphan medicinal products enjoy, upon receiving marketing authorization, a period of ten years of orphan market exclusivity—see also Orphan Drug Designation and Exclusivity. Depending upon the timing and duration of the EU marketing authorization process, products may be eligible for up to five years’ supplementary protection certificates, or SPCs, pursuant to Regulation (EC) No 469/2009. Such SPCs extend the rights under the basic patent for the drug.

Regulatory Requirements after a Marketing Authorization Has Been Obtained

If we obtain authorization for a medicinal product in the European Union, we will be required to comply with a range of requirements applicable to the manufacturing, marketing, promotion and sale of medicinal products.

56

Table of Contents

Pharmacovigilance and Other Requirements

We will, for example, have to comply with the EU’s stringent pharmacovigilance or safety reporting rules, pursuant to which post-authorization studies and additional monitoring obligations can be imposed. Other requirements relate, for example, to the manufacturing of products and APIs in accordance with good manufacturing practice standards. EU regulators may conduct inspections to verify our compliance with applicable requirements, and we will have to continue to expend time, money and effort to remain compliant. Non-compliance with EU requirements regarding safety monitoring or pharmacovigilance, and with requirements related to the development of products for the pediatric population, can also result in significant financial penalties in the European Union. Similarly, failure to comply with the EU’s requirements regarding the protection of individual personal data can also lead to significant penalties and sanctions. Individual EU member states may also impose various sanctions and penalties in case we do not comply with locally applicable requirements.

Manufacturing

The manufacturing of authorized drugs, for which a separate manufacturer’s license is mandatory, must be conducted in strict compliance with the EMA’s Good Manufacturing Practices, or GMP, requirements and comparable requirements of other regulatory bodies in the European Union, which mandate the methods, facilities and controls used in manufacturing, processing and packing of drugs to assure their safety and identity. The EMA enforces its current GMP requirements through mandatory registration of facilities and inspections of those facilities. The EMA may have a coordinating role for these inspections while the responsibility for carrying them out rests with the member states competent authority under whose responsibility the manufacturer falls. Failure to comply with these requirements could interrupt supply and result in delays, unanticipated costs and lost revenues, and could subject the applicant to potential legal or regulatory action, including but not limited to warning letters, suspension of manufacturing, seizure of product, injunctive action or possible civil and criminal penalties.

Marketing and Promotion

The marketing and promotion of authorized drugs, including industry-sponsored continuing medical education and advertising directed toward the prescribers of drugs and/or the general public, are strictly regulated in the European Union under Directive 2001/83/EC and Member States’ national law implementing it. The applicable regulations aim to ensure that information provided by holders of marketing authorizations regarding their products is truthful, balanced and accurately reflects the safety and efficacy claims authorized by the EMA or by the competent authority of the authorizing member state. Failure to comply with these requirements can result in adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties.

Patent Term Extension

In order to compensate the patentee for delays in obtaining a marketing authorization for a patented product, a supplementary protection certificate, or SPC, may be granted extending the exclusivity period for that specific product by up to five years. Applications for SPCs must be made to the relevant patent office in each EU member state and the granted certificates are valid only in the member state of grant. An application has to be made by the patent owner within six months of the first marketing authorization being granted in the European Union (assuming the patent in question has not expired, lapsed or been revoked) or within six months of the grant of the patent (if the marketing authorization is granted first). In the context of SPCs, the term “product” means the active ingredient or combination of active ingredients for a medicinal product and the term “patent” means a patent protecting such a product or a new manufacturing process or application for it. The duration of an SPC is calculated as the difference between the patent’s filing date and the date of the first marketing authorization, minus five years, subject to a maximum term of five years.

A six-month pediatric extension of an SPC may be obtained where the patentee has carried out an agreed pediatric investigation plan, the authorized product information includes information on the results of the studies and the product is authorized in all member states of the EU. The six-month pediatric extension of SPCs is not available for medicinal products that are designated as orphan medicinal products, as such products benefit from a separate two-year pediatric extension of orphan status and exclusivity. The six-month pediatric extension of SPCs is, however, available for medicinal products which were originally designated as orphan medicinal products but were subsequently (voluntarily) removed from the EU’s Community Register of Orphan Medicinal Products; according to a first instance court judgment, an SPC pediatric extension is also available where a designation as orphan drug had been sought but never granted.

On July 1, 2019, EU Regulation 2019/933 entered into force. The Regulation introduced manufacturing waivers for exporting and stockpiling active pharmaceutical ingredients and medicinal products. If certain requirements are met, those actions are now exempted from SPC protection. The patent reform of 2012 that laid the ground for the creation of unitary patent protection in the EU did not explicitly provide for a “unitary SPC”. To ensure that companies which choose unitary patent protection can benefit from the SPC extension, the European Commission is working on the articulation of unitary patent protection and SPC legislation.

UK Regulation

From January 1, 2021, EU law no longer directly applies in the UK. The UK has adopted existing EU medicines regulation as standalone UK legislation with some amendments to reflect procedural and other requirements with respect to marketing authorizations and other regulatory provisions.

In order to market medicines in the UK, manufacturers must hold a UK marketing authorization. Applications may be made through several national routes including the 150-day assessment for national applications and rolling review for marketing authorizations. For a period of two years from January 1, 2021, as part of the application for a UK marketing authorization, Great Britain may rely on a decision taken by the European Commission on the approval of new marketing authorizations in the centralized community marketing authorization procedure (EC Decision reliance Procedure). Such applications must include all information provided to the EMA during the relevant licensing procedure including the final CHMP opinion and must also state whether the applicant intends to apply for orphan designation in the UK. The UK has the power to take into account marketing authorizations made under the EU decentralized and mutual recognition procedures.

UK medicines legislation is subject to future regulatory change under the Medicines and Medical Devices Act 2021. This act sets out a new framework for the adoption of medicines regulation.

Different rules will apply in Northern Ireland following implementation of the Northern Ireland Protocol. In Northern Ireland, EU central marketing applications will continue to apply.

The EU-UK Trade Agreement contains an Annex in relation to medicinal products with the objective of facilitating availability of medicines, promotion of public health and consumer protection in respect of medicinal products between the UK and the EU. The Annex provides for mutual recognition of Good Manufacturing Practice (GMP) inspections and certificates, meaning that manufacturing facilities do not need to undergo duplicate inspections for the two markets. The Annex establishes a Working Group on Medicinal Products to deal with matters under the EU-UK Trade Agreement, facilitate co-operation and for the carrying out of technical discussions. It is expected that further bilateral discussions will continue with respect to regulatory areas not the subject of the EU-UK Trade Agreement, including pharmacovigilance. The EU-UK Trade Agreement also does not include reciprocal arrangements for the recognition of batch testing certification. The UK has listed approved countries, including the EEA which will enable UK importers and wholesales to recognize certain certification and regulatory standards. The UK’s acceptance of batch testing done in EEA countries will be reviewed before December 31, 2022 and a two-year notice period will be given in the case of changes. The European Commission has not adopted such recognition procedures.

The separate UK authorization system, albeit with transitional recognition procedures in the UK, will lead to additional regulatory costs. In addition, additional regulatory costs will be incurred with respect to the lack of mutual recognition of batch testing and related regulatory measures.

Foreign Regulation

In addition to regulations in the United States, the European Union and the UK, we will be subject to a variety of other foreign regulations governing clinical trials and commercial sales and distribution of our products. Whether or not we obtain FDA, EMA or MHRA approval for a product, we must obtain approval by the comparable regulatory authorities of other countries or areas before we may commence clinical trials or market products in those countries or areas. The approval process and requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from place to place, and the time may be longer or shorter than that required for FDA, EMA or MHRA approval.

Pharmaceutical Pricing and Reimbursement

Sales of pharmaceutical products depend in significant part on the extent of coverage and reimbursement from government programs, including Medicare and Medicaid in the U.S., and other third party payers. Third party payers are sensitive to the cost of drugs and are increasingly seeking to implement cost containment measures to control, restrict access to, or influence the purchase of drugs, biologicals, and other health care products and services. Governments may regulate reimbursement, pricing, and coverage of products in order to control costs or to affect levels of use of certain products. Payers may restrict coverage of some products due to cost concerns, by various means such as using payer formularies under which only selected drugs are covered, variable co-payments that make drugs that are not preferred by the payer more expensive in terms of higher out-of-pocket expenses for patients, and by employing utilization management controls, such as discouraging patients’ use of copay coupons and discount cards and imposing requirements for prior authorization before a prescription can be billed or prior clinical failure on another type of treatment before a new product can be prescribed. Payers may especially impose these obstacles to coverage for higher-priced drugs in order to limit the payer’s cost for treatment of the disease. Consequently, any future products may be subject to payer-driven restrictions, rendering patients responsible for a higher percentage of the total cost of drugs in the outpatient setting. This could lower the demand for any future products if the increased patient out-of-pocket cost-sharing obligations are more than they can afford.

Medicare is a U.S. federal government insurance program that covers individuals aged 65 years or older, as well as individuals of any age with certain disabilities, and individuals with End-Stage Renal Disease. The primary Medicare programs that may affect reimbursement for Akari are Medicare Part B, which covers physician services and outpatient care, and Medicare Part D, which provides a voluntary outpatient prescription drug benefit. Medicare Part B provides limited coverage of certain outpatient drugs and biologicals that are reasonable and necessary for diagnosis or treatment of an illness or injury. Under Medicare Part B, reimbursement for most drugs is based on a fixed percentage above the applicable product’s average sales price, or ASP. Manufacturers calculate ASP based on a statutory formula and must report ASP information on a quarterly basis to the Centers for Medicare and Medicaid Services (CMS), the federal agency that administers Medicare and the Medicaid Drug Rebate Program. The current reimbursement rate for drugs and biologicals in both the hospital outpatient department setting and the physician office setting is ASP + 6%. The rate for the physician clinic setting is set by statute, but CMS has the authority to adjust the rate for the hospital outpatient setting on an annual basis. This reimbursement rate may decrease in the future. In both settings, the amount of reimbursement for a product’s usage is updated quarterly based on the manufacturer’s submission of new ASP information about its product or based on the submission of ASP information of each manufacturer that sells a product for which there are multiple competitors in that product market. On October 30, 2018, CMS issued an advance notice of proposed rulemaking (ANPRM) proposing a rule to set prices for certain drugs based on prices paid in other nations. Under the proposal, beginning in 2020 and extending until 2025, CMS would use a model called the IPI to allow Medicare to more closely align its Medicare payment amount for selected Part B drugs with prices paid in other nations and would allow for private-sector vendors to negotiate drug prices, take title to drugs, and compete for physician and hospital business. The current pricing model is based on average sales prices plus a 4.3 percent add-on payment. The IPI model would include mandatory participation from physician practices and hospital outpatient clinics that supply the included drugs. It is uncertain whether CMS’ proposed rule will be issued.

Medicare Part D is a prescription drug benefit available to all Medicare beneficiaries. It is a voluntary benefit that is implemented through private plans under contractual arrangements with the federal government. Similar to pharmaceutical coverage through private health insurance, Part D plans negotiate discounts from drug manufacturers. Medicare Part D coverage is available through private plans, and the list of prescription drugs covered by Part D plans varies by plan. However, individual plans are required by statute to cover certain therapeutic categories and classes of drugs or biologicals and to have at least two drugs in each unique therapeutic category or class, with certain exceptions.

Medicare Part A covers inpatient hospital benefits. Hospitals typically receive a single payment for an inpatient stay depending on the Medicare Severity Diagnosis Related Group (MS-DRG) to which the inpatient stay is assigned. The MS-DRG for a hospital inpatient stay varies based on the patient’s condition. Hospitals generally do not receive separate payment for drugs and biologicals administered to patients during an inpatient hospital stay. As a result, hospitals may not have a financial incentive to utilize any future products for inpatients.

Beginning April 1, 2013, the Budget Control Act of 2011, Pub. L. No. 112-25, as amended by the American Taxpayer Relief Act of 2012, Pub. L. 112-240, required Medicare payments for all items and services, including drugs and biologicals, to be reduced by 2% under sequestration (i.e., automatic spending reductions). Subsequent legislation extended the 2% reduction, on average, to 2025. This 2% reduction in Medicare payments affects all parts of the Medicare program and could impact any future sales of any future products.

On January 20, 2017, Former President Trump took office as the President of the United States. Former President Trump has stated that he intends to “repeal and replace” the Affordable Care Act, and Congress has taken initial steps to repeal the law. In December 2017, Congress passed and the Former President signed into law tax reform legislation that made significant changes to the Affordable Care Act including the repeal of the “individual mandate” that was in place to strongly encourage broad participation in the health insurance markets. Given these changes and other statements of political leaders, we cannot predict the ultimate impact on the Affordable Care Act and the subsequent effect on the pharmaceutical industry at this time. In the fourth quarter of 2018, the Trump Administration announced initiatives that it asserted are intended to result in purportedly lower drug prices. The first initiative, announced on October 15, 2018, involved the plan to a new federal regulation that would require pharmaceutical manufacturers to disclose the list prices of their respective prescription drugs in their television advertisements for their products if the list price is greater than $35 USD. With respect to the second initiative, on October 25, 2018, the Centers for Medicaid and Medicare Services gave Advance Notice of Proposed Rulemaking to propose the implementation of an “International Pricing Index” model for Medicare Part B drugs and biologicals (single source drugs, biologicals, and biosimilars). Public comments were due on December 31, 2018 with a proposed rule theoretically being offered as early as Spring 2019 with target implementation of a five year pilot program beginning in Spring 2020. While these initiatives have not been put into effect, we are not in a position to know at this time whether they will ever become law or what impact the enactment either of these proposals would have on our business.

On October 25, 2018, the Centers for Medicaid and Medicare Services gave Advance Notice of Proposed Rulemaking to propose the implementation of an “International Pricing Index” model for Medicare Part B drugs and biologicals (single source drugs, biologicals, and biosimilars). Public comments were due on December 31, 2018 with a proposed rule theoretically being offered as early as Spring 2019 with target implementation of a 5 year pilot program beginning in Spring 2020. In December 2020, the U.S. District Courts granted temporary nationwide injunctions for the drug pricing model proposed to be effective January 1, 2021, precluding its implementation. In November 2020, Joseph Biden was elected President and, in January 2021, the Democratic Party obtained control of the Senate. In December 2021, the CMS published a final version of the proposed rule, and in January 2022, the Biden administration pulled back the implementation of the proposed rule. We are not able to state with certainty what the impact of these changes will have on our business with regard to these drug pricing initiatives.

As part of its reform of the 340B discount drug program, on October 31, 2018, the HRSA at HHS issued a notice of proposed rulemaking to move up the effective date of a final rule that would give HHS authority to impose Civil Monetary Penalties on pharmaceutical manufacturers who knowingly and intentionally charged a covered entity more than the statutorily allowed ceiling price for a covered outpatient drug. The final rule is intended to encourage compliance by manufacturers in offering the mandatory 340B ceiling purchase price to eligible purchasers, such as certain qualified health systems or individual hospitals.

Various states, such as California, have also taken steps to consider and enact laws or regulations that are intended to increase the visibility of the pricing of pharmaceutical products with the goal of reducing the prices at which we are able to sell our products. Because these various actual and proposed legislative changes are intended to operate on a state-by-state level rather than a national one, we cannot predict what the full effect of these legislative activities may be on our business in the future. Medicaid is a government health insurance program for low-income children, families, pregnant women, and people with disabilities. It is jointly funded by the federal and state governments, and it is administered by individual states within parameters established by the federal government. Coverage and reimbursement for drugs and biologics thus varies by state. Drugs and biologics may be covered under the medical or pharmacy benefit. State Medicaid programs may impose utilization management controls, such as prior authorization, step therapy, or quantity limits on drugs and biologics. Medicaid also includes the Medicaid Drug Rebate Program, under which, as a condition of coverage for our future products by the individual state Medicaid programs, we will be required to pay a retrospective rebate to each state Medicaid program for the quarterly utilization of our products by those respective state Medicaid programs we would be required to pay a rebate to each state Medicaid program for quantities of any future products that are dispensed to Medicaid beneficiaries and paid for by a state Medicaid program as a condition of having federal funds being made available to the states for any future products under Medicaid and Medicare Part B. Those rebates are based on pricing data that would be reported by us on a monthly and quarterly basis to CMS. These data include the average manufacturer price and the best price for each product we sell. As further described below under “U.S. Healthcare Reform and Other U.S. Healthcare Laws,” the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively, the PPACA, made significant changes to the Medicaid Drug Rebate Program that could negatively impact our results of operations.

Federal law requires that any company that participates in the Medicaid Drug Rebate Program also participate in the Public Health Service’s 340B drug discounted pricing program in order for federal funds to be available for the manufacturer’s drugs under Medicaid and Medicare Part B. The 340B pricing program requires participating manufacturers to agree to charge statutorily-defined

60

Table of Contents

covered entities no more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs. These 340B covered entities include a variety of community health clinics and other entities that receive health services grants from the Public Health Service as well as hospitals that serve a disproportionate share of low-income patients. The 340B ceiling price is calculated using a statutory formula, which is based on the average manufacturer price and rebate amount for the covered outpatient drug as calculated under the Medicaid Drug Rebate Program. Changes to the definition of average manufacturer price and the Medicaid rebate amount under PPACA and CMS’s issuance of final regulations implementing those changes also could affect the 340B ceiling price calculation for any future products and could negatively impact our results of operations. As described below under “U.S. Healthcare Reform and Other U.S. Healthcare Laws,” PPACA expanded the 340B program to include additional types of covered entities but exempts “orphan drugs” designated under section 526 of the FDCA from the ceiling price requirements for these newly-eligible entities. CMS has also implemented new regulations that further define and further expand which health care provider entities are eligible to purchase approved drugs at the discounted 340B prices. As part of its reform of the 340B program, on October 31, 2018, the HRSA at HHS issued a notice of proposed rulemaking to move up the effective date of a final rule that would give HHS authority to impose Civil Monetary Penalties on pharmaceutical manufacturers who knowingly and intentionally charged a covered entity more than the statutorily allowed ceiling price for a covered outpatient drug.

In order to be eligible to have products paid for with federal funds under the Medicaid and Medicare Part B programs and purchased by certain federal agencies and grantees, manufacturers must participate in the Department of Veterans Affairs Federal Supply Schedule, or FSS, pricing program, established by Section 603 of the Veterans Health Care Act of 1992, or VHCA. Under this program, we would be obligated to make our innovator “covered drugs” available for procurement on an FSS contract and charge a price to four federal agencies, Department of Veterans Affairs, Department of Defense, Public Health Service and Coast Guard, the so-called “Big Four” government purchasers, that is no higher than the statutory Federal Ceiling Price, or FCP. The FCP is based on the non-federal average manufacturer price, or Non-FAMP, which we would calculate and report to the Department of Veterans Affairs on a quarterly and annual basis. Under the Tricare Retail Pharmacy program, established by Section 703 of the National Defense Authorization Act for FY 2008 and related regulations, participating manufacturers pay quarterly rebates on utilization of innovator products that are dispensed through the Tricare Retail Pharmacy network to Tricare beneficiaries. The rebates are calculated as the difference between Annual Non-FAMP and FCP. The FCP is based on a weighted average non-federal average manufacturer price (Non-FAMP) which manufacturers are required to report on a quarterly and annual basis to the VA. If a company misstates Non-FAMPs or FCPs it must restate these figures and potentially refund to the government purchasers any overcharges that occurred.

Pursuant to the VHCA, knowing provision of false information in connection with a Non-FAMP filing can subject a manufacturer to penalties of one hundred seventy-eight thousand dollars for each item of false information.

Payers also are increasingly considering new metrics as the basis for reimbursement rates, such as ASP, average manufacturer price, and actual acquisition cost. The existing data for reimbursement based on these metrics is relatively limited, although certain states have begun to survey acquisition cost data for the purpose of setting Medicaid reimbursement rates. CMS surveys and publishes retail community pharmacy acquisition cost information in the form of National Average Drug Acquisition Cost files to provide state Medicaid agencies with a basis of comparison for their own reimbursement and pricing methodologies and rates. It may be difficult to project the impact of these evolving reimbursement mechanics on the willingness of payers to cover any future products.

FSS contracts are federal procurement contracts that include standard government terms and conditions, separate pricing for each product, and extensive disclosure and certification requirements. All items on FSS contracts are subject to a standard FSS contract clause that requires FSS contract price reductions under certain circumstances where pricing is reduced to an agreed “tracking customer.” Further, in addition to the “Big Four” agencies, all other federal agencies and some non-federal entities are authorized to access FSS contracts. FSS contractors are permitted to charge FSS purchasers other than the Big Four agencies “negotiated pricing” for covered drugs that is not capped by the FCP; instead, such pricing is negotiated based on a mandatory disclosure of the contractor’s commercial “most favored customer” pricing.

In addition, pursuant to regulations issued by the DoD TRICARE Management Activity, now the Defense Health Agency, to implement Section 703 of the National Defense Authorization Act for Fiscal Year 2008, participating manufacturers have each of their covered drugs listed on a Section 703 Agreement under which they have agreed to pay rebates on covered drug prescriptions dispensed to TRICARE beneficiaries by TRICARE network retail pharmacies. Companies are required to list their innovator products on Section 703 Agreements in order for those products to be eligible for DoD formulary inclusion. The formula for determining the rebate is established in the regulations and our Section 703 Agreement and is based on the difference between the annual Non-FAMP and the FCP (as described above, these price points are required to be calculated by us under the VHCA).

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. Moreover, the requirements governing drug pricing and reimbursement vary widely from country to country. For example, in the EU the sole legal instrument at the EU level governing the pricing and reimbursement of medicinal products is Council Directive 89/105/EEC, or the Price Transparency Directive. The aim of the Price Transparency Directive is to ensure that pricing and reimbursement mechanisms established in EU member states are transparent and objective, do not hinder the free movement and trade of medicinal products in the EU and do not hinder, prevent or distort competition on the market. The Price Transparency Directive does not, however, provide any guidance concerning the specific criteria on the basis of which pricing and reimbursement decisions are to be made in individual EU member states. Neither does it have any direct consequence for pricing or levels of reimbursement in individual EU member states. The national authorities of the individual EU member states are free to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices and/or reimbursement of medicinal products for human use. Some individual EU member states adopt policies according to which a specific price or level of reimbursement is approved for the medicinal product. Other EU member states adopt a system of reference pricing, basing the price or reimbursement level in their territory either, on the pricing and reimbursement levels in other countries, or on the pricing and reimbursement levels of medicinal products intended for the same therapeutic indication. Furthermore, some EU member states impose direct or indirect controls on the profitability of the company placing the medicinal product on the market.

Health Technology Assessment, or HTA, of medicinal products is becoming an increasingly common part of the pricing and reimbursement procedures in some EU member states. These countries include France, Germany and Sweden. The HTA process in the EU member states is governed by the national laws of these countries. HTA is the procedure according to which the assessment of the public health impact, therapeutic impact and the economic and societal impact of the use of a given medicinal product in the national healthcare systems of the individual country is conducted. HTA generally focuses on the clinical efficacy and effectiveness, safety, cost, and cost-effectiveness of individual medicinal products as well as their potential implications for the national healthcare system. Those elements of medicinal products are compared with other treatment options available on the market.

The outcome of HTA may influence the pricing and reimbursement status for specific medicinal products within individual EU member states. The extent to which pricing and reimbursement decisions are influenced by the HTA of a specific medicinal product varies between the EU member states.

In 2011, Directive 2011/24/EU was adopted at the EU level. This Directive concerns the application of patients’ rights in cross-border healthcare. The Directive is intended to establish rules for facilitating access to safe and high-quality cross-border healthcare in the EU. Pursuant to Directive 2011/24/EU, a voluntary network of national authorities or bodies responsible for HTA in the individual EU Member States was established. The purpose of the network is to facilitate and support the exchange of scientific information concerning HTAs.

On December 13, 2021, a new Regulation on HTA on EU level was adopted, Regulation (EU) 2021/2282 of the European Parliament and of the Council of December 15, 2021 on health technology assessment and amending Directive 2011/24/EU (HTA Regulation).

With the “European Network for Health Technology Assessment, “EUnetHTA21” a consortium of thirteen EUnetHTA member organizations has now been commissioned to prepare the implementation of the EU HTA Regulation and thus the future binding joint HTA work.

The regulation covers new medicines and certain new medical devices, “providing the basis for permanent and sustainable cooperation at the EU level for joint clinical assessments in these areas.” Member states will be able to use common HTA tools, methodologies and procedures across the EU, working together in four main areas: 1) joint clinical assessments focusing on the most innovative health technologies with the most potential impact for patients; 2) joint scientific consultations whereby developers can seek advice from HTA authorities; 3) identification of emerging health technologies to identify promising technologies early; and 4) continuing voluntary cooperation in other areas.

Individual member states will continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health technology, and making decisions on pricing and reimbursement.

The HTA Regulation enters into force on January 11, 2022, and will become applicable three years later, i.e. on January 12, 2025.

U.S. Healthcare Reform and Other U.S. Healthcare Laws

In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal healthcare laws, including those commonly referred to as “fraud and abuse” laws have been applied in recent years to restrict certain marketing practices in the pharmaceutical industry. These laws may impact, among other things, our proposed sales, marketing and education programs. In addition, we may be subject to patient privacy regulation by both the U.S. federal government and the states in which we conduct our business. The laws that may affect our ability to operate include the following:

Table of Contents

Sanctions under these federal and state healthcare laws may include civil monetary penalties, exclusion of a manufacturer’s products from reimbursement under government programs, monetary damages, criminal fines, disgorgement, additional reporting obligations and oversight if the manufacture becomes subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, and individual imprisonment.

Federal and state authorities are continuing to devote significant attention and resources to enforcement of fraud and abuse laws within the pharmaceutical industry, and private individuals have been active in alleging violations of the law and bringing suits on behalf of the government under the FCA. For example, federal enforcement agencies recently have investigated certain pharmaceutical companies’ product and patient assistance programs, including manufacturer reimbursement support services, relationships with specialty pharmacies, and grants to independent charitable foundations.

The PPACA was adopted in the U.S. in March 2010. This law substantially changes the way healthcare is financed by both governmental and private insurers in the U.S., and significantly impacts the pharmaceutical industry. PPACA contains a number of provisions that are expected to impact our business and operations. Changes that may affect our business include those governing enrollment in federal healthcare programs, reimbursement changes, rules regarding prescription drug benefits under the health insurance exchanges, expansion of the 340B program, expansion of state Medicaid programs, and fraud and abuse and enforcement. These changes will impact existing government healthcare programs and will result in the development of new programs, including Medicare payment for performance initiatives and improvements to the physician quality reporting system and feedback program.

PPACA contains several provisions that have or could potentially impact our business. PPACA made significant changes to the Medicaid Drug Rebate Program. Effective March 23, 2010, rebate liability expanded from fee-for-service Medicaid utilization to include the utilization of Medicaid managed care organizations as well. With regard to the amount of the rebates owed, PPACA increased the minimum Medicaid rebate from 15.1% to 23.1% of the average manufacturer price for most innovator products; changed the calculation of the rebate for certain innovator products that qualify as line extensions of existing drugs; and capped the total rebate amount for innovator drugs at 100% of the average manufacturer price. In addition, PPACA and subsequent legislation changed the definition of average manufacturer price. In early 2016, CMS issued final regulations to implement the changes to the Medicaid Drug

Rebate Program under PPACA, which became effective on April 1, 2016. Finally, PPACA requires pharmaceutical manufacturers of branded prescription drugs to pay a branded prescription drug fee to the federal government. Each individual pharmaceutical manufacturer pays a prorated share of the branded prescription drug fee of $4,000 in 2017 (and set to increase in ensuing years), based on the dollar value of its branded prescription drug sales to certain federal programs identified in the law. Sales of “orphan drugs” are excluded from this fee. “Orphan drugs” are specifically defined for purposes of the fee. For each indication approved by the FDA for the drug, such indication must have been designated as orphan by the FDA under section 526 of the FDCA, an orphan drug tax credit under section 45C of the Internal Revenue Code must have been claimed with respect to such indication, and such tax credit must not have been disallowed by the IRS. Finally, the FDA must not have approved the drug for any indication other than an orphan indication for which a section 45C orphan drug tax credit was claimed (and not disallowed).

Additional provisions of PPACA may negatively affect manufacturer’s revenues in the future. For example, as part of PPACA’s provisions closing a coverage gap that currently exists in the Medicare Part D prescription drug program (commonly known as the “donut hole”), manufacturers of branded prescription drugs are required to provide a 50% discount on branded prescription drugs dispensed to beneficiaries within this donut hole.

PPACA also expanded the Public Health Service’s 340B drug pricing discount program. The 340B pricing program requires participating manufacturers to agree to charge statutorily-defined covered entities no more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs. PPACA expanded the 340B program to include additional types of covered entities: certain free-standing cancer hospitals, critical access hospitals, rural referral centers and sole community hospitals, each as defined by PPACA. PPACA exempts “orphan drugs” designated under section 526 of the FDCA, from the ceiling price requirements for these newly-eligible entities.

Finally, numerous federal and state laws, including state security breach notification laws, state health information privacy laws, and federal and state consumer protection laws govern the collection, use, and disclosure of personal information. In addition, most healthcare providers and research institutions with whom we collaborate are subject to privacy and security requirements under HIPAA, as amended by HITECH, and its implementing regulations. Although we are currently neither a “covered entity” nor a “business associate” under HIPAA, and these privacy and security requirements do not apply to us, the regulations may affect our interactions with healthcare providers, health plans, and research institutions from whom we obtain patient health information. Further, we could be subject to criminal penalties if we knowingly obtain individually identifiable health information from a HIPAA covered entity in a manner that is not authorized or permitted by HIPAA or for aiding and abetting the violation of HIPAA.

There is significant interest in the United States in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access, including increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices, particularly with respect to drugs that have been subject to relatively large price increases over relatively short time periods. There have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. Although multiple bills to repeal or repeal and replace portions of the PPACA have been introduced in 2017, none of these measures have successfully passed both houses of Congress. Congress may consider other legislation to repeal and replace elements of the PPACA or other health reform measures in the future. However, with the election of Joseph Biden and a change in control of the Senate, it is less likely that Congress will pass legislation to repeal and replace PPACA, but legislation to modify or expand PPACA may be considered.

Other Regulations

We are also subject to the U.S. Foreign Corrupt Practices Act, or FCPA, the U.K. Bribery Act, or Bribery Act, and other anticorruption laws and regulations pertaining to our financial relationships with foreign government officials. The FCPA prohibits U.S. companies and their representatives from paying, offering to pay, promising, or authorizing the payment of anything of value to any foreign government official, government staff member, political party, or political candidate to obtain or retain business or to otherwise seek favorable treatment. In many countries in which we operate, the healthcare professionals with whom we interact may be deemed to be foreign government officials for purposes of the FCPA. The Bribery Act, which applies to any company incorporated or doing business in the UK, prohibits giving, offering, or promising bribes in the public and private sectors, bribing a foreign public official or private person, and failing to have adequate procedures to prevent bribery amongst employees and other agents. Penalties under the Bribery Act include potentially unlimited fines for companies and criminal sanctions for corporate officers under certain circumstances.

Table of Contents

Liability in relation to breaches of the Bribery Act is strict. This means that it is not necessary to demonstrate elements of a corrupt state of mind.

Recent years have seen a substantial increase in anti-bribery law enforcement activity by U.S. regulators, with more frequent and aggressive investigations and enforcement proceedings by both the DOJ and the SEC, increased enforcement activity by non-U.S. regulators, and increases in criminal and civil proceedings brought against companies and individuals. Increasing regulatory scrutiny of the promotional activities of pharmaceutical companies also has been observed in a number of EU member states. In Germany, a specific anti-corruption provision with regard to healthcare professionals was introduced in the Criminal Code in 2017.

Similar strict restrictions are imposed on the promotion and marketing of drug products in the EU, where a large portion of our non-U.S. business is conducted, and other territories. Laws in the EU, including in the individual EU member states, require promotional materials and advertising for drug products to comply with the product’s Summary of Product Characteristics, or SmPC, which is approved by the competent authorities. Promotion of a medicinal product which does not comply with the SmPC is considered to constitute off-label promotion. The off-label promotion of medicinal products is prohibited in the EU and in other territories. The promotion of medicinal products that are not subject to a marketing authorization is also prohibited in the EU. Laws in the EU, including in the individual EU member states, also prohibit the direct-to-consumer advertising of prescription-only medicinal products. Violations of the rules governing the promotion of medicinal products in the EU and in other territories could be penalized by administrative measures, fines and imprisonment. Furthermore, illegal advertising can be challenged by competitors, and as a result, can be prohibited by court and the responsible company can be obligated to pay damages to the competitor.

Interactions between pharmaceutical companies and physicians are also governed by strict laws, regulations, industry self-regulation codes of conduct and physicians’ codes of professional conduct in the individual EU member states. The provision of any inducements to physicians to prescribe, recommend, endorse, order, purchase, supply, use or administer a medicinal product is prohibited. A number of EU member states have introduced additional rules requiring pharmaceutical companies to publicly disclose their interactions with physicians and to obtain approval from employers, professional organizations and/or competent authorities before entering into agreements with physicians. These rules have been supplemented by provisions of related industry codes, including the EFPIA Disclosure Code on Disclosure of Transfers of Value from Pharmaceutical Companies to Healthcare Professionals and Healthcare Organizations and related codes developed at national level in individual EU member states. Additional countries may consider or implement similar laws and regulations. Violations of these rules could lead to reputational risk, public reprimands, and/or the imposition of fines or imprisonment. Our present and future business has been and will continue to be subject to various other laws and regulations. Laws, regulations and recommendations relating to safe working conditions, laboratory practices, the experimental use of animals, and the purchase, storage, movement, import and export and use and disposal of hazardous or potentially hazardous substances, including radioactive compounds, used in connection with our research work are or may be applicable to our activities. We cannot predict the impact of government regulation, which may result from future legislation or administrative action, on our business.

Impact of COVID-19 Outbreak

The situation surrounding the COVID-19 pandemic, including the mutation of variants, continues to remain fluid globally and we continue to manage ongoing challenges associated with the pandemic as they relate to operations. The potential for a material impact on our business, financial condition and results of operation remains a risk. We cannot reasonably estimate with any degree of certainty any future impact of COVID-19. Pandemics such as this can adversely impact our business as a result of disruptions, such as travel bans, quarantines, staffing shortages, and interruptions to access the trial sites and supply chains, which could result in material delays and complications with respect to our research and development programs and clinical trials.

Table of Contents

Moreover, as a result of COVID-19, there is a general unease of conducting certain non-critical activities in medical centers. For example, while now open for enrollment, prior clinical trials have been halted or delayed due to COVID-19. The extent to which COVID-19 impacts operations will depend on future developments, including the scope of any new virus mutations and outbreaks, the nature of government public health guidelines and the public’s adherence to those guidelines, the rate of individuals becoming fully vaccinated and the public’s adherence to guidelines to receive booster vaccinations, and the extent to which new lockdowns may be needed or are required in particular countries, including China. In particular, the continued spread of COVID-19 globally could adversely impact our operations and workforce, including research and clinical trials and the ability to raise capital, could affect the operations of key governmental agencies, such as the FDA, which may delay the development of our product candidates, and could result in the inability of suppliers to deliver components or raw materials, including drug product and drug substance, on a timely basis or at all, each of which in turn could have an adverse impact on our business, financial condition and results of operation.

General and administrative expenses

General and administrative expenses for the year ended December 31, 2020 were approximately $9,161,000 compared to approximately $8,224,000 for the year ended December 31, 2019. This 11% or $937,000 increase was primarily due to a one-time non-cash financing expense of approximately $900,000 related to the 2020 Purchase Agreement with Aspire Capital.

Other Income (expenses)

Other income for the year ended December 31, 2020 was approximately $899,000 compared to $117,000 for the year ended December 31, 2019. This change was primarily attributed to approximately $358,000 of higher income related to the change in the fair value of warrant liabilities in 2020 than in 2019, and foreign exchange gains in 2020 of approximately $351,000 as compared to foreign exchange losses of $67,000 in 2019.

Investment Company, LLC, or the Placement Agent, to serve as our placement agent in connection with this offering. In connection with the offering, we issued to the investors and the Placement Agent registered warrants to purchase 3,720,409 ADSs at $1.40 per ADS and 297,633 ADSs at $1.75 per ADS, respectively.

We believe our current capital resources are sufficient to support our operations into December 2022 without giving effect to the sale of additional shares to Aspire Capital under the 2020 Purchase Agreement.

We are subject to a number of risks similar to those of clinical stage companies, including dependence on key individuals, uncertainty of product development and generation of revenues, dependence on outside sources of capital, risks associated with clinical trials of products, dependence on third-party collaborators for research operations, need for marketing authorization of products, risks associated with protection of intellectual property, and competition with larger, better-capitalized companies. We are closely monitoring ongoing developments in connection with the COVID-19 pandemic, which has resulted in the halting of and disruptions to our ongoing clinical trials and may negatively impact our ability to raise capital. To fully execute our business plan, we will need, among other things, to complete our research and development efforts and clinical and regulatory activities. These activities may take several years and will require significant operating and capital expenditures in the foreseeable future.

For the twelve months ended December 31, 2021, we reported a net loss of $17,424,237 and we expect to continue to incur substantial losses over the next several years during our development phase. To fund our capital needs, we plan to raise additional funds through equity or debt financings or other sources, such as strategic partnerships and alliance and licensing arrangements, and in the long term, from the proceeds from sales of commercial products. To the extent that we raise additional funds by issuing equity securities, our shareholders may experience significant dilution.

These additional funds may not be available when we need them, on terms that are acceptable to us, or at all. Specifically, the COVID-19 pandemic has disrupted global financial markets, and may limit our ability to access capital, which could in the future negatively affect our liquidity. Therefore, there can be no assurance that we will be successful in obtaining an adequate level of financing needed for our research and development efforts and clinical and regulatory activities, which may take several years and will require significant operating and capital expenditures in the foreseeable future. If we are unable to raise sufficient capital resources, we will not be able to continue the development of all of our products, or may be required to delay part of our development programs and significantly reduce our activities in order to maintain our operations. These matters raise substantial doubt about our ability to continue as a going concern. Our independent registered public accounting firm, in its report on our audited financial statements for the year ended December 31, 2021 expressed substantial doubt about our ability to continue as a going concern. The financial statements do not include any adjustments to the carrying amounts and classifications of assets and liabilities that would result if we were unable to continue as a going concern.

Aspire Capital Financing Arrangement

2020 Purchase Agreement

On June 30, 2020, we entered into a second Purchase Agreement with Aspire Capital (“2020 Purchase Agreement”) which provides that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital is committed to purchase up to an aggregate of $30.0 million of our ADSs, during a 30-month period beginning July 27, 2020 on the effective date of a registration statement related to the transaction. Concurrently with entering into the 2020 Purchase Agreement, we also entered into a registration rights agreement with Aspire Capital, or the Registration Rights Agreements in which we agreed to file one or more registration statements, as permissible and necessary to register under the Securities Act, the sale of our securities that have been and may be issued to Aspire Capital under the 2020 Purchase Agreement. Subsequently on September 30, 2020, we filed the registration statement on Form F-1 to register the resale of such securities and such registration statement was declared effective on July 27, 2020.

Under the 2020 Purchase Agreement, after the SEC has declared effective the registration statement referred to above, on any trading day selected by us, we have the right, in our sole discretion, to present Aspire Capital with a purchase notice, each, a Purchase Notice, directing Aspire Capital (as principal) to purchase up to 150,000 ADSs per business day and up to $30.0 million of our ADSs in the aggregate at a per share price, or the Purchase Price, equal to the lesser of:

71

Table of Contents

In addition, on any date on which we submit a Purchase Notice to Aspire Capital in an amount of 150,000 ADSs, the Company also has the right, in its sole discretion, to present Aspire Capital with a volume-weighted average price purchase notice, each, a VWAP Purchase Notice, directing Aspire Capital to purchase an amount of ADSs equal to up to 30% of the aggregate shares of our ADSs traded on our principal market on the next trading day, or the VWAP Purchase Date, subject to a maximum number of 250,000 ADSs. The purchase price per share pursuant to such VWAP Purchase Notice is generally 97% of the volume-weighted average price for our ADSs traded on our principal market on the VWAP Purchase Date.

The Purchase Price will be adjusted for any reorganization, recapitalization, non-cash dividend, stock split, or other similar transaction occurring during the period(s) used to compute the Purchase Price. We may deliver multiple Purchase Notices and VWAP Purchase Notices to Aspire Capital from time to time during the term of the 2020 Purchase Agreement, so long as the most recent purchase has been completed.

The 2020 Purchase Agreement provides that we and Aspire Capital shall not effect any sales under the 2020 Purchase Agreement on any purchase date where the closing sale price of our ADSs is less than $0.25. Additionally, governing law in the United Kingdom, where the Company is incorporated, requires a minimum payment per ADS to be issued pursuant to a purchase notice equal to the nominal value of an ADS (i.e., £1). There are no trading volume requirements or restrictions under the 2020 Purchase Agreement, and the Company will control the timing and amount of sales of the Company’s ADSs to Aspire Capital. Aspire Capital has no right to require any sales by the Company, but is obligated to make purchases from the Company as directed by the Company in accordance with the 2020 Purchase Agreement. There are no limitations on use of proceeds, financial or business covenants, restrictions on future fundings, rights of first refusal, participation rights, penalties or liquidated damages in the 2020 Purchase Agreement. In accordance with ASC 815-40-15, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock, since the ultimate floor price which is effectively the nominal value of the ADS which was denominated in GBP at the time of entering into the 2018 Purchase agreement as well as the 2020 Purchase Agreement (together “the Purchase Agreements”) prior to the 2020 Redenomination, the number of shares issuable under the contract was impacted by foreign currency, therefore ASC 815-40-15-7I precluded the Purchase Agreements from being indexed to the Company’s own stock. The Company determined that the right to sell shares to Aspire Capital under the Purchase Agreements represents a freestanding put option that met the criteria of a derivative pursuant to ASC 815 Derivatives and Hedging. Since the purchase price per share pursuant to the Purchase Agreements is at the market, the Company concluded that the put option has a fair value of zero, and therefore no additional accounting related to the put option was required.

In consideration for entering into the 2020 Purchase Agreement, the Company agreed to issue to Aspire Capital 40,760,900 ordinary shares of the Company, the 2020 Commitment Shares, which had a fair value of approximately $900,000. Because the Company has determined that the 2020 Purchase Agreement is considered a freestanding put option derivative, the Company recorded the value of the 2020 Commitment Shares in the twelve months ended December 31, 2020 in General and administrative expenses in the Consolidated Statements of Comprehensive Income (Loss). The 2020 Purchase Agreement may be terminated by us at any time, at our discretion, without any cost to us. Aspire Capital has agreed that neither it nor any of its agents, representatives and affiliates shall engage in any direct or indirect short-selling or hedging of our securities during any time prior to the termination of the 2020 Purchase Agreement. Any proceeds we receive under the 2020 Purchase Agreement are expected to be used for working capital and general corporate purposes.

To date, we have sold to Aspire Capital a total of approximately $8 million of ordinary shares and $22 million of the original purchase commitment remains available for draw down under the Purchase Agreement.

Net cash provided by financing activities was $12,648,000 during the year ended December 31, 2019 related to draw downs under the Aspire Capital Financing Arrangement and proceeds from the 2019 Registered Direct Offering.

Contractual Obligations

We do not have any significant contractual obligations as of December 31, 2021. We lease office space in London, UK and New York, NY on a short-term basis.

Our research and development expenditures were approximately $9,133,000, $8,820,000 and $8,739,000 for the years ended December 31, 2021, 2020 and 2019 respectively. Most of such research and development expenditures were in the form of payments to third parties to carry out our manufacturing, pre-clinical and clinical research activities.

We incurred the following research and development expenses for the years ended December 31, 2021, 2020 and 2019:

In some cases, we could reasonably have used different accounting policies and estimates. Changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. Significant estimates include, but are not limited to, those related to deferred revenue, revenue recognition, stock-based compensation and fair value of marketable debt securities. For further significant accounting policies please see Note 2 to our audited consolidated financial statements of this annual report. We believe that our accounting policies contained therein are critical in fully understanding and evaluating our financial condition and operating results.

Share-Based Compensation and Fair Value of Ordinary Shares

We account for awards of equity instruments issued to employees and directors under the fair value method of accounting and recognize such amounts in our Consolidated Statements of Comprehensive Loss. We measure compensation cost for all stock-based awards at fair value on the date of grant and recognize compensation expense in general administrative and research and development expenses in our Consolidated Statements of Comprehensive Loss using the straight-line method over the service period over which we expect the awards to vest.

We estimate the fair value of all time-vested options as of the date of grant using the Black-Scholes option valuation model, which was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option valuation models require the input of highly subjective assumptions, including the expected share price volatility, which we calculate based on the historical volatility of peer companies. We use a risk-free interest rate, based on U.S. Treasury instruments in effect at the time of the grant, for the period comparable to the expected term of the option. Given our limited history with share option grants and exercises, we use the “simplified” method in estimating the expected term, the period of time that options granted are expected to be outstanding, for our grants.

We classify our stock-based payments which are settled in our ordinary shares as equity-classified awards. We measure equity-classified awards at their grant date fair value and do not subsequently remeasure them. Compensation costs related to equity-classified awards generally are equal to the grant date fair value of the award amortized over the vesting period of the award.

Warrants issued in connection with our 2019 Registered Direct Offering

In connection with the sale of the ADSs in the 2019 Registered Direct Offering, we issued to investors unregistered warrants to purchase an aggregate of 1,184,213 ADSs in a private placement, or the 2019 Investor Warrants. The 2019 Investor Warrants are immediately exercisable at an exercise price of $3.00 per ADS, subject to adjustment as set forth therein and will expire five years from issuance. We also issued unregistered warrants to the Placement Agent to purchase an aggregate of 177,629 ADSs, or the 2019 Placement Agent Warrants, on the same terms as the 2019 Investor Warrants, except that the 2019 Placement Agent Warrants are exercisable at $2.85 per ADS. The total amount of warrants issued in connection with this registered direct offering amounted to warrants to purchase an aggregate of 1,361,842 ADSs, all of which were outstanding as of December 31, 2021. At grant date, the 2019 Investor Warrants and the 2019 Placement Agent Warrants, or, together, the 2019 Warrants, were recorded as liability-classified awards and accounted for in accordance with ASC 815-40-25, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock and ASC 815-40-15, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock. In accordance with ASC 820, we measured the 2019 Warrants at grant date fair value. The total grant date fair value of the 2019 Warrants

was $1,213,816. On December 8, 2020, the Company held a general meeting (“2020 General Meeting”) and changed the currency of its ordinary shares from pounds sterling to US dollars (“2020 Redenomination”). As a consequence of the 2020 Redenomination, the Company was required to reassess, whether its financial instruments or other contracts that previously required derivative accounting within the scope of ASC 815 Financial Instruments either (a) no longer meet the definition of a derivative or (b) meet a scope exception to the derivative guidance due to a change in facts and circumstances. The Company concluded that due to the 2020 Redenomination, the 2019 Warrants now meet the requirements for classification as equity under ASC 815-40-25 as of December 8, 2020, the date of the 2020 General Meeting. The Company updated the carrying amount of the warrant liability to its fair value on December 8, 2020, with any changes recorded in the Consolidated Statements of Comprehensive Loss and then re-classed the warrant liability balance to additional paid in capital within Shareholders’ Equity.

Warrants issued in connection with the 2020 Private Placements

In connection with the sale of the ADSs in the 2020 Private Placements, we issued to investors unregistered warrants to purchase an aggregate of 2,810,136 ADSs in a private placement, or the 2020 Investor Warrants. The warrants are immediately exercisable at an exercise price of $2.20 per ADS, subject to adjustment as set forth therein and will expire five years from issuance. We also issued unregistered warrants to the Placement Agent to purchase an aggregate of 449,623 ADSs, or February 2020 Placement Agent Warrants, on the same terms as the 2020 Investor Warrants, except that the 2020 Placement Agent Warrants are exercisable at $2.55 per ADS. The total amount of warrants issued in connection with this private placement amounted to warrants to purchase an aggregate of 3,259,759 ADSs. 3,247,259 of these warrants were outstanding as of December 31, 2021. At grant date, the 2020 Investor Warrants and the 2020 Placement Agent Warrants, or, together, the 2020 Warrants were recorded as liability-classified awards and accounted for in accordance with ASC 815-40-25, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock and ASC 815-40-15, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock. In accordance with ASC 820, we measured the 2020 Warrants at grant date fair value. The total grant date fair value of the 2020 Warrants was $2,749,369. The Company concluded that due to the 2020 Redenomination, the 2020 Warrants now meet the requirements for classification as equity under ASC 815-40-25 as of December 8, 2020, the date of the 2020 General Meeting. The Company updated the carrying amount of the warrant liability to its fair value on December 8, 2020, with any changes recorded in the Consolidated Statements of Comprehensive Loss and then reclassed the warrant liability balance to additional paid in capital within Shareholders’ Equity.

Warrants issued in connection with the 2021 Private Placements

In connection with the sale of the ADSs in the 2021 Private Placements, we issued unregistered warrants to the Placement Agent to purchase an aggregate of 398,384 ADSs, or 2021 Warrants. The 2021 Warrants are immediately exercisable at an exercise price of $2.32 per ADS, subject to adjustment as set forth therein and will expire five years from issuance. The Company has determined that, at the time of their issuance, the 2021 Warrants met the requirements for classification as equity under ASC 815-40-25. In connection with the 2021 Private Placements, the costs directly attributable to realizing proceeds of issuing ADSs such as placement agent fees, commissions, legal and accounting fees pertaining to the financing and other external, incremental fees and expenses paid to advisors are recognized in additional paid-in capital of the Shareholders’ Equity in the Consolidated Balance Sheets in accordance with ASC 814-40. At grant date on July 16, 2021, the fair value of the 2021 Warrants was $231,063 and was recorded within additional paid-in capital of Shareholders’ Equity.

Commitment Shares issued in connection with the 2020 Purchase Agreement

In consideration for entering into the 2020 Purchase Agreement, we agreed to issue to Aspire Capital 40,760,900 ordinary shares of the Company (the “2020 Commitment Shares”) which had a fair value of approximately $900,000. Since we have determined that the 2020 Purchase Agreement includes a freestanding put option that meets the criteria of a derivative in accordance with ASC 815-40-15, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock, we recorded the fair value of the 2020 Commitment Shares in General and administrative expenses in the Consolidated Statements of Comprehensive Income (Loss).

The option plan is administered by our board of directors and grants are made pursuant thereto by the compensation committee. The aggregate number of ordinary shares that may be issued upon exercise of options under the 2014 Plan is 400,000,000. Options may be granted at any time. As of December 31, 2021, options to purchase 142,949,035 of our ordinary shares were outstanding under the 2014 Plan. Unless sooner terminated, the Plan shall expire on April 30, 2024.

The per share exercise price for the shares to be issued pursuant to the exercise of an option shall be such price as determined by the board of directors and set forth in the individual option agreement, subject to any guidelines as may be determined by the board of directors from time to time, provided, however, that the exercise price shall be not less than the par value of the shares underlying the option, and subject to other conditions set forth in the 2014 Plan.

Options are exercisable pursuant to the terms under which they were awarded and subject to the terms and conditions of the 2014 Plan. In general, an option, or any part thereof, may not be exercised unless the optionee is then a service provider of our Company or any parent or subsidiary thereof (as each such term is defined in the 2014 Plan). Any tax consequences arising from the grant or exercise of any option from the payment for shares covered thereby, the sale or disposition of such shares and any other expenses are the responsibility of the optionee unless otherwise required by applicable law.

On January 23, 2017, the compensation committee approved a UK Sub-Plan of the 2014 Plan which offers UK residents the opportunity to acquire interests in us in a similar manner to that offered to US employees. The UK Sub-Plan requires that only employees may receive grants, and that all options granted under the UK Sub-Plan must be designated as “non-tax-advantaged Options” under UK law. Options granted under the UK Sub-Plan are exercisable pursuant to the terms of their award and are subject to the terms of the 2014 Plan generally, except where otherwise stated. The UK Sub-Plan differs from the 2014 Plan only in UK-specific provisions regarding a valid disposition to survivors and compliance with local UK laws regarding securities, treatment as compensation, tax matters, data privacy, and third party rights.

Grants to non-employee directors who are based in the UK or who are UK resident taxpayers are made pursuant to the 2014 Plan in accordance with the UK Appendix to the Amended and Restated Non-Employee Director Compensation Policy which was approved by the compensation committee on January 23, 2017. The UK Appendix, as with the Sub-Plan for employees, differs from the Non-Employee Director Compensation Policy by providing specific UK-specific provisions. All options granted to UK non-employee directors or resident taxpayers are, as with the Sub-Plan for employees, designated as “non-tax-advantaged options” under UK law, exercisable pursuant to the terms of the award and the 2014 Plan, and provide for UK specific provisions regarding survivorship, securities, compensation, tax, data privacy, and third party rights laws.

In addition, on January 26, 2017, our board of directors approved a CSOP Sub Plan as recommended to the board by the compensation committee. The CSOP Sub-Plan modifies the 2014 Plan to qualify as a Schedule 4 CSOP Scheme as defined under the UK’s Income Tax (Earnings & Pensions) Act 2003, or ITEPA. The purpose of the CSOP Sub-Plan is to allow options granted to UK resident employees and directors to qualify as a Schedule 4 CSOP Scheme under governing law and to therefore qualify for certain tax advantages under ITEPA. CSOP options are effectuated by the execution of a deed of grant by the Company evidencing shares, option exercise price, restrictions, and other terms or conditions. Grants are limited under the CSOP Sub-Plan such that an employee cannot hold more than £30,000 in value, measured as of grant date. In the event of redundancy, retirement, a relevant transfer within the meaning of the Protection of Employment regulations, or a cease of control (as defined in Section 719 ITEPA) under governing UK law, the recipient may exercise any CSOP option that has become exercisable but has not yet been exercised for a period of six months. A Change of Control under UK law will similarly permit option exercise.

2007 Stock Option Plan

On August 28, 2007, our board of directors approved the 2007 Stock Option Plan, or the 2007 Stock Option Plan, as amended on April 26, 2012, June 20, 2012 and April 29, 2013. The shareholders approved the 2007 Stock Option Plan on June 20, 2013. The purpose of the 2007 Stock Option Plan was to provide an additional incentive to employees, officers, directors, consultants and other service providers of the Company and any parent or subsidiary of the Company (each as defined in the 2007 Stock Option Plan) to further the growth, development and financial success of the Company by providing them with opportunities to purchase shares pursuant to the 2007 Stock Option Plan and to promote the success of the business. The material terms of the 2007 Stock Option Plan are set forth below.

The option plan was administered by the board of directors and grants were made pursuant thereto by the compensation committee. The aggregate number of ordinary shares that could be issued upon exercise of options under the 2007 Stock Option Plan could not exceed 5,865,000 ordinary shares. The board of directors could have, at any time during the term of the 2007 Stock Option Plan, increased the number of shares available for grant under the 2007 Stock Option Plan. As of August 28, 2017, options to purchase 480,000 of our ordinary shares were outstanding under the 2007 Stock Option Plan when the Plan expired on the tenth anniversary of its effective date. As of December 31, 2021, there were no options outstanding under the 2007 Stock Option Plan.

In general, an option, or any part thereof, could not be exercised unless the optionee was then a service provider of our Company or any parent or subsidiary thereof (as each such term is defined in the 2007 Stock Option Plan). Any tax consequences arising from the grant or exercise of any option from the payment for shares covered thereby, the sale or disposition of such shares and any other expenses was the responsibility of the optionee unless otherwise required by applicable law.

Equity Award Grant Policy

Based on the recommendation of the compensation committee, our board of directors adopted an Equity Award Grant Policy on January 26, 2017, which sets forth policies for us to follow when we grant stock options, shares of restricted stock, restricted stock units or other equity-based awards to employees of the Company or its subsidiaries.

The grants are divided into annual grants, made on the last business day in March, new hire grants, to our new hires, and performance grants to existing employees in recognition of performance. The policy standardizes employee grants and delegates authority to the Executive Chairman and CEO to make grants other than (a) grants of more than 1,000,000 ordinary shares or share-equivalents to one individual on one date; (b) new hire or performance grants to a person who is reasonably expected to be an executive officer or director upon hire or promotion; (c) any grant which would exceed 1,000,000 ordinary shares or share equivalents to any one individual in a calendar year; or (d) any grant with an exercise price less than fair market value on the date. These non-delegated grants remain in the sole authority of the compensation committee.

Pricing will be based on the closing market price on the Nasdaq Capital Market for all such grants. All new-hire grants must be made by a writing sent to the recipient stating the terms and conditions and clarifying that the equity award is subject to approval, whether by the delegated authority pursuant to the policy or by the compensation committee or the board itself.
