1. Business overview

Summary of business

COSCIENS Biopharma Inc. (the “Company”), formerly Aeterna Zentaris Inc., is a specialty biopharmaceutical company developing and commercializing a diversified portfolio of cosmeceutical, nutraceutical and pharmaceutical products. The Company’s patented technologies include Pressurized Gas eXpanded (PGX) technology that generates high-value yields of active ingredients from natural plant resources for use in novel cosmeceutical, nutraceutical and therapeutics products. The Company’s two value-driving active ingredient products, oat beta glucan and avenanthramides, are found in many household name cosmetic and personal care brands. These products are manufactured from the Company’s proprietary oat extraction manufacturing technology and are known for their health benefits.

The Company’s lead pharmaceutical product, macimorelin (Macrilen; Ghryvelin), is the first and only U.S. FDA and European Commission approved oral test indicated for the diagnosis of adult growth hormone deficiency (AGHD). The Company is leveraging the clinical success and safety profile of macimorelin to develop it for the diagnosis of childhood-onset growth hormone deficiency (CGHD).

The Company is also dedicated to the development of its therapeutic assets and has established a pre-clinical development pipeline to potentially address unmet medical needs across a number of indications, including treatment of inflammation-based diseases, idiopathic pulmonary fibrosis (IPF), neuromyelitis optica spectrum disorder (NMOSD), Parkinson’s disease (PD), hypoparathyroidism and amyotrophic lateral sclerosis (ALS; Lou Gehrig’s disease).

Transaction

On December 14, 2023, Aeterna Zentaris Inc. (“Aeterna”) and Ceapro Inc. (“Ceapro”) entered into a binding arrangement agreement pursuant to which Aeterna would acquire all of the issued and outstanding common shares of Ceapro (the “Transaction”) by way of a plan of arrangement pursuant to which, at closing, each outstanding Ceapro common share would be exchanged for 0.02360 of a Aeterna common share (the “Plan of Arrangement”). Additionally, as part of the Transaction, Aeterna would issue to its shareholders immediately prior to the closing of the Transaction, 0.47698 of a share purchase warrant (“New Warrant”) for each Aeterna common share or warrant held. On March 12, 2024, the shareholders of both Ceapro and Aeterna approved the Plan of Arrangement at their respective special meetings. On March 28, 2024, the Court of Kings Bench of Alberta approved the Plan of Arrangement. The Transaction was consummated on June 3, 2024.

Following the closing of the Transaction, former shareholders of Ceapro owned approximately 50% of the Aeterna common shares on a fully diluted basis and former shareholders of Aeterna owned approximately 50% of the Aeterna common shares on a fully diluted basis. For financial reporting and accounting purposes, Ceapro is the acquirer of Aeterna in the Transaction. The consolidated financial statements of COSCIENS Biopharma Inc. as of June 30, 2024 and December 31, 2023 and for the three and six months ended June 30, 2024 and 2023 reflect the results of operations and financial position of Ceapro for the periods presented and includes 28 days of the results of operations of Aeterna as of June 30, 2024 and for three and six months ended June 30, 2024 subsequent to the Transaction, which was completed on June 3, 2024. Refer to Note 3 for additional information.

The accompanying consolidated financial statements include the accounts of COSCIENS Biopharma Inc., an entity incorporated under the Canada Business Corporations Act, and its wholly owned subsidiaries (the “Group”). COSCIENS Biopharma Inc. is the ultimate parent company of the Group. The Company currently has six wholly-owned direct and indirect subsidiaries, Ceapro Inc. and its wholly-owned subsidiaries Ceapro (P.E.I.) and Juvente^DC Inc., based in Canada, Aeterna Zentaris GmbH (“AEZS Germany”) and its wholly-owned subsidiary Zentaris IVF GmbH, based in Frankfurt, Germany, and Aeterna Zentaris, Inc., an entity incorporated in the state of Delaware and with offices in Summerville, South Carolina, in the US.

The registered office of the Company is located at 222 Bay Street, Suite 3000, P.O. Box 53, Toronto, Ontario M5K 1E7, Canada.

The Company’s common shares are listed on both the Toronto Stock Exchange under the symbol CSCI (previously AEZS) and on the NASDAQ Capital Market under the symbol CSCI (previously AEZS).

2. Basis of presentation

These unaudited condensed interim consolidated financial statements have been prepared in accordance with IAS 34, Interim Financial Reporting as issued by the International Accounting Standards Board.

The unaudited condensed interim consolidated financial statements do not include all the notes normally included in annual consolidated financial statements. The unaudited condensed interim consolidated financial statements reflect all normal and reoccurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Accordingly, these unaudited condensed interim consolidated financial statements should be read in conjunction with the Ceapro’s annual consolidated financial statements as of and for the year ended December 31, 2023.

The accounting policies used in these condensed interim consolidated financial statements are consistent with those presented in Ceapro’s annual consolidated financial statements, except for the accounting policies as described below:

Business combinations

Business combinations are accounted for using the acquisition method as at the acquisition date when control is transferred. The consideration transferred for the acquisition of a business is the fair value of the assets transferred, and any liability and equity interests issued by the Company to the former owners of the acquired business on the acquisition date. Identifiable assets acquired and liabilities assumed in a business combination are generally measured initially at their fair values at the acquisition date. Acquisition-related costs other than those associated with the issue of debt or equity securities, and other direct costs of a business combination are not considered part of the business acquisition transaction and are expensed as incurred.

Foreign currency

Effective June 30, 2024, Ceapro has changed its reporting currency from Canadian dollars to U.S. dollars. This change in reporting currency has been applied retrospectively such that all amounts in the consolidated financial statements of the Company and the accompanying notes thereto are expressed in U.S. dollars. References to “$” are U.S. dollars and references to “CA $” are to Canadian dollars. For comparative purposes, historical consolidated financial statements of Ceapro were recast in U.S. dollars by translating assets and liabilities at the closing exchange rate in effect at the end of the respective period, revenues, expenses and cash flows at the average exchange rate in effect for the respective period and equity transactions at historical exchange rates. Translation gains and losses are included in the cumulative foreign currency translation adjustment, which is reported as a component of shareholders’ equity under accumulated other comprehensive loss.

As of June 30, 2024, and for the three and six months ended June 30, 2024, and 2023

(In thousands of US dollars, except share and per share data and as otherwise noted)

(Unaudited)

Post-employment benefits

The Company has partially funded and unfunded defined benefit multi-employer pension plans, namely the DUPK pension plan and the RUK 1990 and 2006 pension plans, (the “Pension Benefit Plans”) and unfunded post-employment benefit plans in Germany. Provisions for pension obligations are established for benefits payable in the form of retirement, disability and surviving dependent pensions. The Company also provides defined contribution plans to some of its employees.

For defined benefit pension plans and other post-employment benefits, net periodic pension expense is actuarially determined on a quarterly basis using the projected unit credit method. The cost of pension and other benefits earned by employees is determined by applying certain assumptions, including discount rates, rate of pension benefit increases, the projected age of employees upon retirement and the expected rate of future compensation.

The employee future benefits liability is recognized at its present value, which is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related future benefit liability. Actuarial gains and losses that arise in calculating the present value of the defined benefit obligation are recognized in other comprehensive loss, net of tax, and simultaneously reclassified in the deficit in the consolidated statement of financial position in the year in which the actuarial gains and losses arise and without recycling to the consolidated statement of loss and comprehensive loss in subsequent periods.

Revenue

The Company generates revenue from supply agreements and licensing agreements with customers for the sale of certain finished goods, semi-finished goods and active pharmaceutical ingredients. The license is generally combined with other promises to supply goods to the customer, and revenue from the combined performance obligation is satisfied at a point in time, which occurs upon shipment. The transaction price for the combined performance obligation includes the license non-refundable non-creditable upfront payment, regulatory milestones, royalties and the selling price of each good supplied. Milestone payments, which are oftentimes payable upon the successful achievement of development or regulatory events, and royalties are included in the transaction price using the most likely amount method only if the milestones are considered probable of being reached and the Company concludes it is highly probable that a significant revenue reversal will not occur. Milestone payments and royalties that are not within the control of the Company or the licensee, such as regulatory approvals, are generally not considered probable of being achieved until those approvals or subsequent sales are received. The Company allocates the transaction price to the projected units that the Company expects to supply pursuant to the contract, estimated based on current projections and anticipated market demand.

Intangible assets

Intangible assets, consisting of patents, that are acquired by the Company and have finite useful lives are measured at cost less accumulated amortization and any accumulated impairment losses. Patents are amortized on their respective remaining patent life and are expiring between 2027 and 2041.

Warrant liabilities

Warrant liabilities are derivative financial instruments. They are initially measured at fair value. Subsequent to initial recognition, they are measured at fair value, and changes therein are recognised in profit or loss.

(Unaudited)

Reclassifications

Certain prior period amounts have been reclassified to conform to current period presentation. In the consolidated statement of financial position, trade receivables of $126 and other receivable of $164 were classified to trade and other receivables. In the consolidated statements of loss for the six months ended June 30, 2023, the general and administration expenses of $2,336 (for the three months ended June 30, 2023 - $1,210) and the sales and marketing expenses of $16 (for the three months ended June 30, 2023 - $10) were reclassified within Selling, general and administrative expenses.

New standards and amendments

Several amendments apply for the first time for reporting periods beginning after January 1, 2024, but do not have an impact on the interim condensed consolidated financial statements of the Company. The IASB has published several new, but not yet effective, standards, amendments to existing standards, and interpretations. None of these standards, amendments to existing standards, or interpretations have been early adopted by the Company, and management anticipates that all relevant pronouncements will be adopted for the first period beginning on or after the effective date of the pronouncement. No pronouncements have been disclosed as they are not expected to have a material impact on the Company’s condensed interim consolidated financial statements.

Critical accounting estimates and judgements

The preparation of condensed interim consolidated financial statements in accordance with IFRS requires management to make judgements, estimates and assumptions about the future that affect the reported amounts of the Company’s assets, liabilities, revenues, expenses and related disclosures. Judgements, estimates and assumptions are based on historical experience, expectations, current trends and other factors that management believes to be relevant at the time at which the Company’s condensed interim consolidated financial statements are prepared.

Management reviews, on a regular basis, the Company’s accounting policies, assumptions, estimates and judgements in order to ensure that the condensed interim consolidated financial statements are presented fairly and in accordance with IFRS applicable to interim financial statements. Revisions to estimates are recognized prospectively. Critical accounting estimates and assumptions, as well as critical judgements used in applying accounting policies in the preparation of the Company’s condensed interim consolidated financial statements, were the same as those applied to Ceapro’s annual consolidated financial statements as of and for the year ended December 31, 2023, except for as described below:

	●	Measurement of defined benefit obligations: key actuarial assumptions (note 10); and
	●	Business acquisition: identification of the acquirer, determination of the fair value of the consideration transferred and fair value of some of the assets acquired and liabilities assumed (note 3).

3. Acquisition of Aeterna Zentaris Inc.

As discussed in Note 1, Business Overview, as a result of the Transaction, Ceapro acquired control of Aeterna Zentaris Inc. on June 3, 2024. Aeterna is a specialty biopharmaceutical company commercializing and developing therapeutics and diagnostic tests. Aeterna’s lead product, Macrilen® (macimorelin), is the first and only U.S. FDA and EMA approved oral test indicated for the diagnosis of patients with adult growth hormone deficiency (“AGHD”). Macimorelin is currently marketed under the tradename Ghryvelin™ in the European Economic Area and the United Kingdom through an exclusive licensing agreement with Pharmanovia. Aeterna is actively pursuing business development opportunities for the commercialization of macimorelin in North America, Asia and the rest of the world. Aeterna is also dedicated to the development of therapeutic assets and has taken steps to establish a pre-clinical pipeline to potentially address unmet medical needs across several indications with a focus on rare or orphan indications.

The Transaction was accounted for as a reverse acquisition under the acquisition method of accounting for business combinations. Ceapro was considered to be the accounting acquirer, and Aeterna was considered the legal acquirer. The amounts recorded for certain assets and liabilities are preliminary in nature and are subject to adjustment as additional information is obtained about the facts and circumstances that existed as of the acquisition date. The final determination of the fair values of certain assets and liabilities will be completed within the measurement period of up to one year from the acquisition date. Under the acquisition method of accounting, total consideration exchanged and allocation of the purchase price to the fair values of assets acquired and liabilities assumed in the Transaction were as follows:

The fair value of the 1,213,967 common shares deemed issued to Aeterna shareholders of $6.99 per share was based on the listed share price of Ceapro as at June 3, 2024 (CA$0.225), after giving effect to the exchange of each outstanding Ceapro common share for 0.02360 of a Aeterna common share and the foreign currency exchange rate.

The fair value of the 633,543 New Warrants issued to Aeterna shareholders was based on the listed share price of Ceapro as at June 3, 2024 of $6.99 (CA$0.225) less the exercise price of $0.01, after giving effect to the exchange of each outstanding Ceapro Common Share for 0.02360 of a Aeterna Zentaris Common Share and the foreign currency exchange rate.

(3)

In accordance with the terms of the Plan of Arrangement, Aeterna’s share-based payment awards held by employees of Aeterna continued with no modifications and are deemed to be replacement awards issued.

The fair value of the replacement awards is $356, after taking into account an estimated forfeiture rate of nil. The consideration for the business combination includes $9 for equity-settled options and $344 for cash-settled DSUs transferred to employees of Aeterna when the acquiree’s awards were substituted by the replacement awards, which relates to past service. The balance of $3 will be recognized as post-acquisition compensation cost.

The fair value at acquisition date was estimated using a Black-Scholes option pricing model, considering the terms and conditions upon which the options were granted, using the following assumptions:

	Options
Expected dividend yield	$	0.0
Weighted average expected volatility		65	%
Weighted average risk-free rate		4.01	%
Weighted average expected life (years)		2.87
Share price	$	6.99
Weighted average exercise price	$	50.15
Weighted average fair value	$	0.90

The expected volatility of these options was determined using historical volatility rates and the expected life was determined using the weighted average life of past options issued.

The fair value of the replacement DSUs of $6.99 per DSU was based on the listed share price of Ceapro as at June 3, 2024 (CA$0.225), after giving effect to the exchange of each outstanding Ceapro common share for 0.02360 of a Aeterna common share and the foreign currency exchange rate.

(4)

The fair value of the 114,405 warrants deemed issued to Aeterna warrant holders was estimated using a Black-Scholes option pricing model, considering the terms and conditions upon which the warrants were issued, using the following assumptions:

	Warrants
Expected dividend yield	$	0.00
Weighted average expected volatility		65	%
Weighted average risk-free rate		4.47	%
Weighted average expected life (years)		1.19
Share price	$	6.99
Weighted average exercise price	$	87.04
Weighted average fair value	$	0.02

(5)

The identifiable intangible assets consist of patents expiring between 2027 and 2041 which will be amortized on their respective remaining patent life. To estimate the fair value of the intangible assets, management uses the royalty relief method to value patents using discounted cash flow models. Management developed assumptions related to revenue and EBITDA margin forecasts, attrition rates, royalty rates and discount rates.

For the period subsequent to the Transaction, Aeterna contributed revenue of $3 and net loss of $214 to the Company’s results. If the acquisition had occurred on January 1, 2024, management estimates that revenue would have been $4,399 and consolidated net loss for the year would have been $12,035. In determining these amounts, management has assumed that the fair value adjustments that arose on the date of acquisition would have been the same if the acquisition had occurred on January 1, 2024.

The Company incurred acquisition-related costs of $4,081 on legal fees and due diligence costs. These costs have been included in Selling, general and administrative expenses as incurred.

4. Revenue

The Company derives revenue from the transfer of goods at a point in time in the following categories:


	Three months ended				Six months ended
	June 30,				June 30,
	2024		2023		2024		2023
		$		$		$		$
Active ingredients		2,334		1,392		4,391		3,977
Pharmaceutical		3		-		3		-
Total		2,337		1,392		4,394		3,977

Deferred revenue

The deferred revenue balance primarily relates to the advance consideration received in the form of non-refundable non-creditable upfront payment and milestone payments relating to list price approvals of Ghryvelin™ in the United Kingdom, Spain and Germany as per an exclusive licensing agreement for the commercialization of macimorelin (the “Licensed Product”) in the European Economic Area and the United Kingdom and an exclusive supply agreement for a period of ten years, subject to renewal, to supply such Licensed Product.

Revenue for this contract will be recognized based on units of Licensed Product supplied. The total units that the Company expects to supply pursuant to the Pharmanovia Agreement is an estimate, based on current projections and anticipated market demand, and therefore will be a significant judgment that will be relied upon when using the outputs method to recognize revenue. The Company expects to recognize the balance of the deferred revenue over the remaining period of eight years, subject to extension based on the outcome of the ongoing clinical development related to the Pediatric Indication and related patent application initiatives. For the three months and six months ended June 30, 2024, the Company recognized $nil and $nil respectively as revenue from the deferred revenue balance originating from the acquisition of Aeterna Zentaris Inc. (note 3).

(In thousands of US dollars, except share and per share data and as otherwise noted)

(Unaudited)

The expected volatility of these stock options was determined using historical volatility rates and the expected life was determined using the weighted average life of past options issued.

The compensation expense for the three months ended June 30, 2024, was $13 (2023 – $43) and for the six months ended June 30, 2024, was $27 (2023 – $142) recognized over the vesting period. Option activity for the six months ended June 30, 2024, and 2023, was as follows:

	Stock options			Weighted average exercise price
	#			$
Balance – January 1, 2024		74,371			20.74
Granted - Replacement options (note 3)		12,949			50.65

Balance – June 30, 2023	84,323		20.46

Concurrent with the Transaction described in Note 1, Business Overview, on June 3, 2024, each outstanding stock option was reissued to reflect the exchange rate of the Company’s common shares and to convert the exercise price into U.S. dollar. Accordingly, all quantities and prices in these interim condensed consolidated financial statements have been retroactively adjusted for all periods presented to give effect to the share exchange and related adjustments.

14. Fair value of financial instruments

The following presents financial assets and liabilities measured at fair value in the statement of financial position in accordance with the fair value hierarchy.

In establishing fair value, the Company uses a fair value hierarchy based on levels as defined below:

	●	Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities at the reporting date;
	●	Level 2: inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and
	●	Level 3: inputs that are based on little or no observable market data, therefore requiring entities to develop their own assumptions.

The Company has determined that, excluding the derivative warrants, the carrying amounts of its current financial assets and financial liabilities approximate their fair value given the short-term nature of these instruments.

As at June 30, 2024 and December 31, 2023, the warrants is the only financial instrument measured at fair value in the condensed interim consolidated statement of financial position. The warrants having an exercise price of $0.01 are classified in level 2 and their fair value has been estimated by reference to the quoted price of the underlying shares at the reporting date. The fair value of all other warrants measured at fair value are classified in level 3.

Key Operational Developments

Active ingredients

The Company’s active ingredient segment focuses on leveraging our unique expertise in the extraction, production and commercialization of active ingredients from natural sources. The Company’s commercialized products are well positioned in the cosmeceutical market and mostly focused on the documented health benefits of two bio actives extracted from oats; beta glucan and avenanthramides. These products include:

	●	A commercial line of natural active ingredients, including beta glucan, avenanthramides (colloidal oat extract), oat powder, oat oil, and oat peptides, which are marketed to the personal care, cosmetic, medical, and animal health industries through our distribution partners and direct sales;
	●	A commercial line of natural anti-aging skincare products, utilizing active ingredients including oat beta glucan and avenanthramides, which are marketed to the cosmeceuticals market through our wholly owned subsidiary, Juvente^DC Inc.; and
	●	Veterinary therapeutic products, including an oat shampoo, an ear cleanser, and a dermal complex/conditioner, which are manufactured and marketed to veterinarians in Japan and Asia.

The Company’s core technologies used to extract and process bio actives include proprietary Ethanol Fractionation Processes (EFP) and Pressurized Gas eXpanded (PGX) Technology. EFP is mostly used to produce liquid formulations while PGX is used for powder formulations. PGX is a patented, unique and disruptive technology with several key advantages over conventional drying and purification technologies that can be used to process biopolymers into high-value and novel biocomposites. In a single step and using green solvents, It has the ability to make generates purified highly porous polymer composites such as aerogels which cannot be made using conventional drying technologies. In 2023, the Company commenced a collaboration with Austria-based NATEX Prozesstechnologie GesmbH to accelerate the scale-up of PGX Technology towards commercial levels at both its Edmonton facility and at the Natex Termitz facility, which are both expected to be completed in 2024.

Given the well-known properties of oat beta glucan and avenanthramides as cholesterol reducer and anti-inflammation respectively, we are actively developing our oat-based pipeline products to address unmet needs within the nutraceuticals markets, with a strategic focus on:

Oat Beta Glucan – Chewable for cholesterol reduction

Leveraging approved claims for the use of oat beta glucan as a proven cholesterol reduction ingredient in Canada, the United States of America and the European Union, and having received approval from Health Canada in December 2023, the Company has formulated a healthy edible product capable of delivering the appropriate dose of oat beta glucan to meet all regulatory and health requirements. Commercial manufacturing samples have been produced, proving manufacturability of a healthy and delicious edible product despite the high levels of oat beta glucan required to provide a scientifically proven cholesterol reduction in humans. The Company intends to bring this product to the wellness and functional food market B2C via various e-commerce platforms.

Avenanthramides – nutraceutical-chewable formulation to reduce inflammation

In addition to cosmetic applications, avenanthramides, when taken orally, could treat inflammation-based conditions such as exercise induced inflammation, joint inflammation as well as inflammation at the gastro-intestinal and cardiovascular levels.

Through the use of a unique chromatography purification technology, the Company has successfully developed a highly purified and well characterized pharmaceutical grade powder formulation with the goal that such active pharmaceutical ingredient (API) could be offered as both nutraceutical and pharmaceutical formulations.

The Company’s initial activities for use of avenanthramides in nutraceuticals were focused on assessing the bio-availability and bio-efficacy of the compound under the leadership of Dr. Li Li Ji at the University of Minnesota. Following the completion of the bio-availablity study in 2018, the Company successfully completed two bio-efficacy studies in 2019 using low and high doses of avenanthramides with young men and women demonstrating in a statistically significant manner the efficacy of avenanthramides in alleviating exercise-induced inflammation as evidenced by a significant decrease of inflammation biomarkers in the blood. These studies paved the way for the development of products like superfine oat flour enriched with Avenanthramides used for the production of chewable oat bar as a nutraceutical as well as for the development of a pharmaceutical grade tablet for clinical trials. The Company is initiating the production of enriched oat flour at small commercial scale at the Edmonton facility.

Beta glucan from yeast (YBG)- nutraceutical-capsule as an immune booster

While yeast beta glucan is a commercial product with well-known immune properties, the obtention of a consistently high-purity product represents a major challenge for suppliers. Using the PGX technology, the company has successfully processed several formulations of yeast beta glucan and is now in a position to offer a very high purity YBG product with very well-defined specifications. The company further demonstrated the mechanism of action following in vitro and in vivo studies.

This product has been used for the completion of the 5 times scale-up of the PGX technology at the Edmonton facility and will also be used for the 10 times scale-up work being conducted in Austria. Powder formulation produced in Edmonton will be offered in capsules as an immune booster product.

Pharmaceutical

The Company is also dedicated to the development of its pharmaceutical therapeutic assets and has established a clinical and pre-clinical development pipeline to potentially address unmet medical needs across a number of indications, including diagnostic tests for growth hormone deficiency, potential treatment of inflammation based diseases, and fibrotic diseases such idiopathic pulmonary fibrosis (IPF), neurodegenerative conditions like neuromyelitis optica spectrum disorder (NMOSD), Parkinson’s disease (PD), hypoparathyroidism), amyotrophic lateral sclerosis (ALS; Lou Gehrig’s disease).) and endocrinology pathologies like hypoparathyroidism.

Macimorelin Commercialization Program

Macrilen^®(macimorelin), is the first and only U.S. Food and Drug Administration (“FDA”) and European Medicines Agency (“EMA”) approved oral test indicated for the diagnosis of patients with adult growth hormone deficiency (“AGHD”). Macimorelin is currently marketed under the tradename Ghryvelin^® in the European Economic Area and the United Kingdom through an exclusive licensing agreement with Pharmanovia. To date the product has launched in the United Kingdom, Sweden, Denmark, Finland, Germany, Netherlands and Austria. More EU countries will follow pending re-imbursement negotiations. The Company’s several other license and commercialization partners are also seeking approval for commercialization of macimorelin in Israel and the Palestinian Authority, the Republic of Korea, Turkey and several non-European Union Balkan countries. The Company is actively pursuing business development opportunities for the commercialization of macimorelin in North America, Asia and the rest of the world.

Macimorelin Clinical Program

In late 2020, the Company entered into the start-up phase for the clinical safety and efficacy study, AEZS-130-P02 (“DETECT-trial”), evaluating macimorelin for the diagnosis of child growth hormone deficiency (CGHD). The DETECT-trial is an open-label, single dose, multicenter and multinational study was expected to enroll approximately 100 subjects worldwide (incl. sites in U.S: and EU), with at least 40 pre-pubertal and 40 pubertal subjects. The study design was expected to be suitable to support a claim for potential stand-alone testing, if successful. On April 22, 2021, the U.S. FDA Investigational New Drug Application associated with this clinical trial became active, (see: https://clinicaltrials.gov/ct2/show/NCT04786873), and in Q2, 2024, the last patient visit was conducted successfully in Europe and the study had enrolled a combined 100 subjects in Europe and North America. The Company remains on track to report top-line data for the DETECT-trial in Q3 2024.

Avenanthramides for Potential Applications in Inflammation Based Diseases

Avenanthramides have garnered significant interest due to their suggested bioactivities, including potent antioxidant and anti-inflammatory effects both in vitro and in vivo. In November 2023, the Company initiated its Phase 1 safety study evaluating its flagship product, avenanthramides, for potential applications in managing conditions related to inflammation. The Phase 1-2a study (“AvenActive”) is a double-blind, placebo-controlled, randomized, adaptive, first-in-human study designed to assess safety, tolerability, and pharmacokinetics of single and multiple ascending oral doses of avenanthramide. 72 healthy subjects will be enrolled in the Phase 1 portion of the trial. The single ascending dose (SAD) arm includes 6 cohorts of 8 healthy subjects, while the multiple ascending dose (MAD) arm will include 3 cohorts of 8 healthy subjects.

The first arm of the SAD phase of the study has been completed with 6 groups of 8 healthy subjects per group received doses ranging from 30mg to 960mg per group per day. No significant adverse reactions have been observed during this SAD phase. The Company expects to initiate the MAD arm during Q3, the summer 2024. Following the Phase 1 portion, pending successful results, the AvenActive protocol also includes a Phase 2a portion for patients presenting evidence of mild to moderate inflammation. A total of 24 patients will be enrolled in the Phase 2a portion.

The Phase 1-2a trial is designed to evaluate the safety profile of avenanthramides and gather initial insights into its potential efficacy. As the trial progresses, the Company remains focused on collaborating with regulatory authorities, healthcare professionals, and patient communities to bring this innovative therapy to market.

Yeast Beta Glucan as treatment for Idiopathic Pulmonary Fibrosis (IPF)

IPF is a progressive disease with a median survival from 2-7 years. While IPF can occur at any age, up to 1 out of every 200 individuals above age 65 will have IPF. With an aging population as well as a significant number of COVID-19 patients developing IPF post infection, prevalence and impact of IPF are expected to grow.

PGX-processed yeast beta glucan (PGX-YBG) can be uniformly “loaded” with a variety of bioactives as a delivery system for inhaled therapeutics. In 2019, the Company, in partnership with McMaster University, initiated a review of preliminary data collected to assess delivery systems to optimize drug formulations used for treatment of Idiopathic Pulmonary Fibrosis (IPF). While yeast beta glucan appeared to be a promising compound, researchers believe the ideal formulation to treat fibrotic lung disorders would be to develop an inhalable complex produced by loading a currently marketed drug onto PGX-YBG. Following preliminary experiments with PGX-YBG alone and in combination with the commercialized a drug, the team concluded that PGX-YBG could be used as a stand-alone the active component to treat fibrotic in a new antifibrotic treatment for the most severe lung diseases including COVID-19 patients.

In 2023, in partnership with McMaster University, we completed a further pre-clinical CHRP study evaluating PGX-YBG as a potential therapeutic option for individuals suffering from interstitial lung diseases (ILD). The positive results from the CHRP study not only, demonstrated that PGX-YBG was respirable, but it could safely and reliably reprogram macrophages in the lungs of mice, providing confidence in its potential to safely penetrate deep into human lungs when self-administered using a hand-held inhaler. These results were presented at the 2023 CSPS/CC-CRS Annual Symposium – The Next Frontiers in Pharmaceutical Sciences to on May 24-26, 2023.

The company is evaluating the next steps for PGX-YBG for ILD. If the company decides to progress it to clinical trial as a potential inhalable immune-therapeutic treatment for severe forms of ILD which may include IPF and COVID-19 related lung fibrosis, we would first be required to undertake and obtain results from IND enabling toxicology studies before.

AIM Biologicals: Targeted, highly specific autoimmunity modifying therapeutics for the potential treatment of neuromyelitis optica spectrum disorder (NMOSD) and Parkinson’s disease

AIM Biologicals are based on a natural process during pregnancy, which induces immunogenic tolerance of the maternal immune system to the partially foreign fetal antigens. Fetal proteins are processed and presented on certain immunosuppressive major histocompatibility complex class I molecules to induce this tolerance. In an autoimmune disease, the immune system is misdirected and targets the body’s own protein. With AIM Biologicals, we aim to restore the tolerance against such proteins to treat autoimmune diseases. Our AIM Biologics program is focused on the rare and orphan indication NMOSD and on the second most common neurodegenerative disorder, Parkinson’s disease.

In January 2021, we entered into an exclusive patent license and research agreement with the University of Wuerzburg, Germany, for worldwide rights to develop, manufacture, and commercialize AIM Biologicals for the potential treatment of NMOSD. Additionally, we have engaged neuro-immunologist Dr. Michael Levy from the Massachusetts General Hospital (“MGH”) in Boston as consultants for scientific support and advice in the field of inflammatory central nervous system “CNS” disorders, autoimmune diseases of the nervous system, and NMOSD. In September 2021, we entered into an additional exclusive license with the University of Wuerzburg for early pre-clinical development towards the potential treatment of Parkinson’s disease. On May 12, 2022 we announced positive pre-clinical results in an innovative mouse model of Parkinson’s disease, where treatment with α-Synuclein specific AIM Biologicals showed a trend towards improved motoric function, as well as significant induction of regulatory T cells and rescue of substantia nigra neurons. The data were presented at IMMUNOLOGY2022™, the annual event of the American Association of Immunologists, held on May 6-10, 2022 in Portland, Oregon. On June 13, 2022, we announced that we had achieved proof-of-concept for the treatment of NMOSD in both in-vitro and in mouse models. These findings were presented at the 13^th International Congress on Autoimmunity on June 10-13, 2022, in Athens, Greece. In October 2022, we entered into a research and development agreement with MGH in Boston and Dr. Michael Levy, to conduct pre-clinical ex-vivo and in-vivo studies in NMOSD.

NMOSD is an autoimmune disease targeting the protein aquaporin 4, primarily found in optic nerves and the spinal cord. The disease leading to blindness and paralysis has a prevalence of 0.7-10 in 100,000. NMOSD progresses in often life-threatening relapses, which are aggressively treated with high-dose steroids and plasmapheresis. Current treatment options include treatment with immunosuppressive monoclonal antibodies, which carries risk of serious infections. We are evaluating the data obtained to date and considering our plans for the treatment of NMOSD using an AIM Biologicals platform.

Parkinson’s disease is a neurological disease commonly associated with motoric problems with a slow and fast progression form. It is the second most common neurodegenerative disease affecting 10 million people worldwide. The hallmark of PD is the neuronal inclusion of mainly α-synuclein protein (αSyn) associated with the death of dopamine-producing cells. Dopaminergic medication is the mainstay treatment of PD symptoms. Up to now there is no pharmacological therapy available to prevent or delay disease progression. For the development of AIM Biologicals as potential PD therapeutics, Aeterna utilizes, among others, an innovative animal model on neurodegeneration by α-synuclein-specific T cells in AAV-A53T-α-synuclein Parkinson’s disease mice, which has recently been published by University of Wuerzburg researchers. We are currently continuing in-vitro and in-vivo testing of antigen-specific AIM Biologics candidate molecules for the potential treatment of Parkinson’s disease.

AEZS-150 – Delayed Clearance (“DC”) Parathyroid Hormone (“PTH”) (“DC-PTH”) Fusion Polypeptides: Potential treatment for chronic hypoparathyroidism

On March 11, 2021, we entered into an exclusive license agreement with The University of Sheffield, United Kingdom, for the intellectual property relating to PTH fusion polypeptides covering the field of human use, which will initially be studied by Aeterna for the potential therapeutic treatment of chronic hypoparathyroidism (“HypoPT”). Under the terms of the agreement, we obtained worldwide rights to develop, manufacture and commercialize PTH fusion polypeptides covered by the licensed patent applications for all human uses. We will be responsible for the further development, manufacturing, approval, and commercialization of the licensed products.

The researchers at the University of Sheffield have developed a method to increase the serum clearance time of peptides, which the Company is applying to the development of a treatment for HypoPT. HypoPT is an orphan disease where the PTH level is abnormally low or absent, with a prevalence per 100,000 of 37 in the U.S., 22 in Denmark, 9.4 in Norway, and 5.3 to 27 in Italy. Standard treatment is calcium and vitamin D supplementation. The lead candidate AEZS-150 is being developed to provide a weekly treatment option of chronic hypoparathyroidism in adults. Recent progress includes the successful verification and reproduction of previous in-vivo data from the University of Sheffield, in a rat model of hypoparathyroidism. We are also reviewing the potential manufacturing process for AEZS-150 with the Company’s contract development and manufacturing organization.

AEZS-130 - Macimorelin Pre-clinical Program

On January 13, 2021, we entered into a material transfer agreement with Queensland University and subsequently in July 2022, into a research and option to license agreement with UniQuest Pty Ltd., the commercialization company of The University of Queensland (UQ), Brisbane, Australia, to conduct of preclinical studies and advance the development of macimorelin as a potential therapeutic for the treatment of ALS.

ALS is a rare progressive neurological disease primarily affecting the neurons controlling voluntary movement, leading to the disability to control movements such as walking, talking, and chewing. Most people with ALS die from respiratory failure, usually between 3-5 years after diagnosis. Currently there is no cure for ALS and no effective treatment to halt or reverse the progression of the disease. Ghrelin is a hormone with wide-ranging biological actions, most known for stimulating growth hormone release, which is demonstrating emerging evidence as therapeutic for ALS.

Through research we are funding at The University of Queensland, we have been conducting pre-clinical experiments to seek to identify a potential alternative formulation suitable for use in ALS patients, the results of which we are currently evaluating.

Historical quarterly results of operations and net loss cannot be taken as reflective of recurring revenue or expenditure patterns of predictable trends, largely given the non-recurring nature of certain components of our revenues, unpredictable quarterly variations in net finance income and of foreign exchange gains and losses. Historical quarterly sales and results primarily fluctuate due to variations in the timing of customer orders, different product mixes, and changes in the optimal use of our capacity to manufacture products.

Liquidity and capital resources

The Company’s objective in managing capital, consisting of shareholders’ equity, with cash and cash equivalents being its primary components, is to ensure sufficient liquidity to fund research and development costs, production costs, selling expenses, general and administrative expenses and working capital requirements. Over the past several years, we have raised capital via public and private equity offerings and issuances and have entered licensing and collaborative arrangements, consideration from which, together with proceeds from equity issuances, has been our primary source of liquidity. The capital management objective of the Company remains the same as that in previous periods. The policy on dividends is to retain cash to keep funds available, to finance the activities required to advance the Company’s product development portfolio and to pursue appropriate commercial opportunities as they may arise. The Company is not subject to any capital requirements imposed by any regulators or by any other external source.

Operating Activities

Cash used by operating activities was $1.4 million for the three-month period ended June 30, 2024, as compared to $0.8 million in the same period in 2023. This $0.6 million increase in operating cash outflows is attributed primarily to:

	●	an increase in research and development costs of $0.8 million due primarily to increase in costs associated with the avenanthramides and DETECT clinical trials; and
	●	an increase in selling, general and administrative costs of $1.8 million due primarily to the acquisition of Aeterna; offset by
	●	An increase in operating assets and liabilities of $2.0 million, primarily due to the acquisition of Aeterna.

Cash used by operating activities was $3.8 million for the six-month period ended June 30, 2024, as compared to $1.6 million in the same period in 2023. This $2.2 million increase in operating cash outflows is attributed primarily to:

	●	A decrease in gross margin of $0.3 million, primarily due to higher costs of sales during the period;
	●	an increase in research and development costs of $1.5 million due primarily to increase in costs associated with the avenanthramides and DETECT clinical trials; and
	●	an increase in selling, general and administrative of $2.4 million due primarily to the acquisition of Aeterna; offset by
	●	An increase in operating assets and liabilities of $2.0 million, primarily due to the acquisition of Aeterna.

Investing activities

Cash provided by investing activities totaled $25.9 million for the three-month period ended June 30, 2024, as compared to $0.1 million in the same period in 2023. This $25.8 million increase in investing cash inflows is attributed primarily to cash inflows associated with the acquisition of Aeterna of $26.0 million offset by $0.2 million in purchases of property and equipment.

Capital Stock

As of August 9, 2024, we had 3,115,974 common shares issued and outstanding, as well as, 80,878 stock options, 114,230 deferred share units and 693,534 warrants outstanding. Each stock option, deferred share unit and warrant is exercisable for one common share.

Adequacy of financial resources

As of June 30, 2024, the Company had retained earnings of $6.7 million, a net loss of $1.4 million and negative cash flows from operations of $1.4 million for the three-month period ended June 30, 2024. We believe that our existing cash on hand will be sufficient to fund our anticipated operating and capital expenditure requirements for at least the next 12 months. We plan to finance our future operations and capital expenditures primarily through products sales and cash on hand. We also believe that our existing cash on hand will be sufficient to fund our anticipated operating and capital expenditure requirements beyond the next 12 months and through 2025. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our capital resources sooner than we expect. We may also require additional capital to pursue in-licenses or acquisitions of other product candidates.

Our forecast of the period through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially as a result of a number of factors. Our future capital requirements are difficult to forecast and will depend on many factors, including:

	●	the terms and timing of any other collaboration, licensing, and other arrangements that we may establish;
	●	the initiation, progress, timing, and completion of preclinical studies and clinical trials for our current and future potential product candidates, as well as other research and development programs;
	●	our alignment with the FDA on regulatory approval requirements;
	●	the number and characteristics of product candidates that we pursue;
	●	the outcome, timing, and cost of regulatory approvals;
	●	delays that may be caused by changing regulatory requirements;
	●	the cost and timing of hiring new employees to support our continued growth and potential expense associated with any loss of key personnel;
	●	the costs involved in filing and prosecuting patent applications and enforcing and defending patent claims;
	●	the costs of filing and prosecuting intellectual property rights and enforcing and defending any intellectual property-related claims;
	●	the costs associated with any potential late receipt or non-receipt of trade and other receivables;
	●	the potential costs associated with foreign currency fluctuations or changing interest rates;
	●	our ability to expand our customer base and related demand fluctuations;
	●	the costs associated with any potential interruption or quality impacts on raw material supplies;
	●	the costs of responding to and defending ourselves against complaints and potential litigation;
	●	the costs and timing of procuring clinical and commercial supplies for our product candidates; and
	●	the extent to which we acquire or in-license other product candidates and technologies.

In addition to the other information included in this MD&A and in the related consolidated financial statements, investors are urged to carefully consider the risks described under the heading “Risk Factors” in our most recent Annual Report on Form 20-F for the year ended December 31, 2023 and under the heading “Risks and Uncertainties” in Exhibit 99.2 of our Form 6-K furnished to the SEC on May 14, 2024, for a discussion of the various risks that may materially affect our business. The risks and uncertainties not presently known to us or that we currently deem immaterial may also materially harm our business, operating results and financial condition and could result in a complete loss of your investment.

Our most recent Annual Report on Form 20-F and Exhibit 99.2 of our Form 6-K furnished to the SEC on May 14, 2024 were filed with the relevant Canadian and U.S. securities’ regulatory authorities at www.sedarplus.ca and with the SEC at www.sec.gov. Investors are urged to consult the risk factors in these documents.

Disclosure Controls and Procedures

The Chief Executive Officer and the Chief Financial Officer of the Corporation are responsible for establishing and maintaining our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act and Canadian securities legislation).  Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under U.S. and Canadian securities legislation is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s  rules and forms, and that such information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosures.

Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objective and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.  There have been no significant changes to our disclosure controls and procedures for the three-month period ended June 30, 2024, that have materially affected, or are reasonably likely to materially affect, the disclosure controls and procedures.

Internal Controls over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act and Canadian securities legislation). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS as issued by the IASB.

Our internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of Aeterna Zentaris; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS as issued by the IASB, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the issuer; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Company assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Controls over Financial Reporting

On June 3, 2024, we completed the business combination transaction with Ceapro, which was accounted for a reverse acquisition. We are currently in the process of integrating Ceapro’s internal controls over financial reporting. Other than with respect to the Ceapro business combination, there have been no significant changes to our internal controls over financial reporting for the three-month period ended June 30, 2024, that have materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.

Fair value of financial instruments

14. Fair value of financial instruments

The following presents financial assets and liabilities measured at fair value in the statement of financial position in accordance with the fair value hierarchy.

In establishing fair value, the Company uses a fair value hierarchy based on levels as defined below:

	●	Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities at the reporting date;
	●	Level 2: inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and
	●	Level 3: inputs that are based on little or no observable market data, therefore requiring entities to develop their own assumptions.

In determining these amounts, management has assumed that the fair value adjustments that arose on the date of acquisition would have been the same if the acquisition had occurred on January 1, 2024.
