ABOUT IMMUNOMEDICS, INC.

Overview

Immunomedics is a clinical-stage biopharmaceutical company developing monoclonal antibody-based products for the targeted treatment of cancer and other serious diseases. Our advanced proprietary technologies allow us to create humanized antibodies that can be used either alone in unlabeled or “naked” form, or conjugated with radioactive isotopes, chemotherapeutics, cytokines or toxins. Using these technologies, we have built a pipeline of six clinical-stage product candidates.

We believe that each of our antibodies has therapeutic potential either when administered as a naked antibody or when conjugated with chemotherapeutics, therapeutic radioisotopes (radiolabeled), cytokines or other toxins to create unique and potentially more effective treatment options. The attachment of various compounds to antibodies is intended to allow the delivery of these therapeutic agents to tumor sites with better specificity than conventional chemotherapy or radiation therapy approaches. This treatment method is designed to reduce the total exposure of the patient to the therapeutic agents, which ideally minimizes debilitating side effects.

Our portfolio of investigational products includes antibody-drug conjugates (“ADCs”) that are designed to deliver a specific payload of a chemotherapeutic directly to the tumor while reducing overall toxicities that are usually found with conventional administration of these chemotherapeutic agents. Our most advanced ADC is sacituzumab govitecan (“IMMU-132”).  In metastatic triple-negative breast cancer (“mTNBC”), a Biologics License Application (“BLA”) is under review with the FDA for potential accelerated approval and a Phase 3 randomized trial (“ASCENT”) in mTNBC patients who have received  at least 2 prior therapies for metastatic disease is well under way.  A single arm trial with registration intent in relapsed/refractory urothelial carcinoma has also been initiated.  Other tumor types and indications are also being explored. Labetuzumab govitecan (“IMMU-130”), completed a Phase 1/2 trial in colorectal cancer (“CRC”).  Further development is under consideration. Sacituzumab govitecan is our lead product candidate and has received Breakthrough Therapy Designation from the U.S. Food and Drug Administration (the “FDA”) for the treatment of patients with mTNBC who have received at least two prior therapies for metastatic disease.

Our corporate strategy is to bring sacituzumab govitecan to the market on our own in the United States for the benefit of patients with mTNBC and the creation of value for our stockholders. In May 2018, we submitted a BLA to the FDA for accelerated approval of sacituzumab govitecan. To fulfil part of the accelerated approval requirements, we also initiated and dosed the first patient into the Phase 3 ASCENT trial of sacituzumab govitecan for mTNBC during the fourth quarter of calendar year 2017.

We believe our current focus on commercializing sacituzumab govitecan as a third-line therapy for patients with mTNBC is also the key to opening the door to further potential commercial opportunities in the future including developing sacituzumab govitecan in earlier lines of therapy in mTNBC, as a monotherapy or in combination therapies, as well as expansion of sacituzumab govitecan into other indications beyond mTNBC, such as advanced urothelial cancer (“UC”), advanced castration-resistant prostate cancer (“CRPC”), small-cell lung cancer (“SCLC’), and non-small-cell lung cancer (“NSCLC”). It’s only by proving sacituzumab govitecan in mTNBC that we can explore, expand into, and potentially capitalize on these new opportunities. While our immediate focus is on commercializing sacituzumab govitecan, on our own, in the U.S. and potentially European markets, we are alert to opportunities to commercialize sacituzumab govitecan in certain other regional markets, and we are also open to business development opportunities to develop other pipeline assets.

These other product candidates, which target solid tumors and hematologic malignancies, as well as other diseases, are in various stages of clinical and pre-clinical development. They include other ADCs such as labetuzumab govitecan, which binds the CEACAM5 antigen expressed on colorectal and other solid cancers, and IMMU-140 that targets HLA-DR for the potential treatment of liquid cancers; IMMU-114, the parental antibody in IMMU-140 that targets the HLA-DR receptor; combination therapies involving our ADCs; bispecific antibodies targeting cancers and infectious diseases as T-cell redirecting immunotherapies; as well as bispecific antibodies for next-generation cancer disease therapies, created using our patented DOCK-AND-LOCK® (“DNL®”) protein conjugation technology. We believe that our portfolio of intellectual property provides commercially reasonable protection for our product candidates and technologies. In addition, we have a research collaboration with Bayer to study epratuzumab as a thorium-227-labeled antibody and an ongoing collaboration with an independent cancer study group to evaluate epratuzumab in

combination with chemotherapy in a large, randomized, Phase 3 trial in children with relapsed acute lymphoblastic leukemia (“ALL”).

The development and commercialization of successful therapeutic products is subject to numerous risks and uncertainties including, without limitation, the following:

·                   we may be unable to obtain additional capital through strategic collaborations, licensing, issuance of convertible debt securities or equity financing in order to continue our research and secure regulatory approval of and market our drug;

·                   the type of therapeutic compound under investigation and nature of the disease in connection with which the compound is being studied;

·                   our ability, as well as the ability of our partners, to conduct and complete clinical trials on a timely basis;

·                   the time required for us to comply with all applicable federal, state and foreign legal requirements, including, without limitation, our receipt of the necessary approvals of the FDA, if at all;

If indicated in the applicable prospectus supplement, underwriters or other persons acting as agents may be authorized to solicit offers by institutions or other suitable purchasers to purchase the securities at the public offering price set forth in the prospectus supplement, pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the prospectus supplement. These purchasers may include, among others, commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions. Delayed delivery contracts will be subject to the condition that the purchase of the securities covered by the delayed delivery contracts will not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which the purchaser is subject. The underwriters and agents will not have any responsibility with respect to the validity or performance of these contracts.

We or the selling stockholders may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we or the selling stockholders may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment). In addition, we or the selling stockholders may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.

General Information

Underwriters, dealers and agents that participate in the distribution of our securities may be underwriters as defined in the Securities Act, and any discounts or commissions they receive and any profit they make on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. Any underwriters or agents will be identified and their compensation described in a prospectus supplement. We may indemnify agents, underwriters, and dealers against certain civil liabilities, including liabilities under the Securities Act, or make contributions to payments they may be required to make relating to those liabilities. Our agents, underwriters, and dealers, or their affiliates, may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

Each series of securities offered by this prospectus may be a new issue of securities with no established trading market. Any underwriters to whom securities offered by this prospectus are sold by us for public offering and sale may make a market in the securities offered by this prospectus, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the trading market for any securities offered by this prospectus.

Representatives of the underwriters through whom our securities are sold for public offering and sale may engage in over-allotment, stabilizing transactions, syndicate short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves syndicate sales in excess of the offering size, which creates a syndicate short position. Stabilizing transactions permit bids to purchase the offered securities so long as the stabilizing bids do not exceed a specified maximum.

Syndicate covering transactions involve purchases of the offered securities in the open market after the distribution

has been completed in order to cover syndicate short positions. Penalty bids permit the representative of the underwriters to reclaim a selling concession from a syndicate member when the offered securities originally sold by such syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Such stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the offered securities to be higher than it would otherwise be in the absence of such transactions. These transactions may be effected on a national securities exchange and, if commenced, may be discontinued at any time.

Underwriters, dealers and agents may be customers of, engage in transactions with or perform services for, us and our subsidiaries in the ordinary course of business.

Selling stockholders may use this prospectus in connection with resales of securities they hold as described in the applicable prospectus supplement, in a post-effective amendment, in a free writing prospectus or in filings we make with the SEC under the Exchange Act that are incorporated by reference. Selling stockholders may be deemed to be underwriters under the Securities Act in connection with the securities they resell and any profits on the sales may be deemed to be underwriting discounts and commissions under the Securities Act.

We will bear all costs, expenses and fees in connection with the registration of the securities as well as the expense of all commissions and discounts, if any, attributable to the sales of any of our securities by us or the selling stockholders.

Pursuant to Section 102(b)(7) of the Delaware General Corporation Law, Article X of our certificate of incorporation eliminates the liability of a director to us or our stockholders for monetary damages for such a breach of fiduciary duty as a director, except for liabilities arising:

·                   from any breach of the director’s duty of loyalty to us or our stockholders;

·                   from acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

·                   under Section 174 of the Delaware General Corporation Law; and

·                   from any transaction from which the director derived an improper personal benefit.

We carry insurance policies insuring our directors and officers against certain liabilities that they may incur in their capacity as directors and officers.

Any underwriting agreements that we may enter into will likely provide for the indemnification of the registrant, its controlling persons, its directors and certain of its officers by the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended.

which remain unsold at the termination of the offering.

(5)          That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i)              Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)           Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6)          That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer and sell such securities to such purchaser:

(i)              Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)           Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)        The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)       Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)          The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial  bona fide  offering thereof.

(c)           Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any

action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
