BOCA RATON, Fla., March 14, 2024 (GLOBE NEWSWIRE) -- First Wave BioPharma, Inc., (NASDAQ: FWBI), (“First Wave BioPharma” or the “Company”), a clinical-stage biopharmaceutical company specializing in the development of targeted, non-systemic therapies for gastrointestinal (GI) diseases, today announced it has acquired ImmunogenX in an all-stock transaction with the combined company focused on advancing a GI pipeline comprised of multiple, late-stage clinical assets, including latiglutenase, a potentially first-in-class, near Phase 3-ready, targeted, oral biotherapeutic for celiac disease. James Sapirstein will continue to serve as Chairman and Chief Executive Officer of First Wave BioPharma with Jack Syage, Ph.D., previously the Chief Executive Officer and Co-Founder of ImmunogenX, assuming the role of President and Chief Operating Officer of First Wave BioPharma. Dr. Syage and Dr. Chaitan Khosla will also join the board of directors of First Wave BioPharma.

First Wave BioPharma intends to license the commercial rights to latiglutenase in the United States and Canada to a strategic global pharmaceutical company which will commercialize latiglutenase following receipt of marketing approval. First Wave BioPharma will also seek to secure financing commitments from a syndicate of institutional healthcare investors to fund the ongoing development of latiglutenase. The closing of a strategic licensing agreement and any other financings would be contingent upon the satisfaction of a number of conditions, including customary due diligence, the negotiation and execution of definitive agreements, Board approval and receipt of all required third-party (including governmental) approvals, licenses, consents, and clearances, as and when applicable.

Latiglutenase, an oral biotherapeutic composed of two gluten-specific recombinant proteases, has demonstrated effectiveness in reducing intestinal damage and alleviating symptoms of celiac disease in two Phase 2 trials involving approximately 200 patients. The Phase 3 clinical plan for latiglutenase has been reviewed by the GI Division of the U.S. Food and Drug Administration (FDA) and the trials are anticipated to begin in early 2025.

“Completion of the acquisition of ImmunogenX and the addition of latiglutenase to our clinical pipeline is a transformative event for First Wave BioPharma as it provides our company with a Phase 3-ready asset in a multibillion-dollar GI market – celiac disease – for which no approved pharmacologic treatment currently exists,” stated Mr. Sapirstein. “Given this enormous potential, we are working with Dr. Syage and his team to advance the regulatory, manufacturing, and clinical processes that would enable the initiation of the pivotal Phase 3 clinical trials of latiglutenase in 2025. To that end, we will seek to develop latiglutenase by completing an agreement with a global pharmaceutical company to provide First Wave with non-dilutive financing in exchange for U.S. and Canadian rights to the drug and to obtain financing with a syndicate of leading institutional healthcare funds in 2H’24. We expect to finalize these agreements prior to initiating preparatory work for the Phase 3 latiglutenase trials.”

Dr. Syage commented: “I am excited to join First Wave BioPharma and advance the company’s mission to become a leading developer of targeted, orally delivered therapeutics for GI diseases. We believe latiglutenase has the potential to transform the treatment of celiac disease with data from two prior Phase 2 trials indicating the therapy is well tolerated and effective in degrading the key gluten proteins responsible for intestinal damage and celiac disease symptoms. This merger with First Wave will provide the support needed to propel the development of latiglutenase, a program that has already received significant NIH grant funding and encouragement from the FDA.”

Mr. Sapirstein concluded: “First Wave BioPharma now possesses a GI-development pipeline unrivaled by other companies of similar size. In addition to latiglutenase, our product portfolio includes capeserod, a selective 5-HT4 receptor partial agonist in-licensed from Sanofi, which is being developed for an anticipated Phase 2 trial in gastroparesis, and Phase 2-ready adrulipase, a recombinant lipase designed to enable the digestion of fats and improve nutritional health in cystic fibrosis patients with exocrine pancreatic insufficiency.”

Upon closing of the acquisition, the Company issued 365,162 shares of its common stock to the shareholders (including option and warrant holders) of ImmunogenX equal to 19.02% of its currently issued and outstanding common stock and 11,777.418 shares of its newly issued Series G Convertible Preferred Stock (with a conversion ratio of Preferred to Common at 1:1000) representing on a fully diluted basis 81.9% for ImmunogenX and 18.1% for First Wave Biopharma (excluding transaction fees) with a combined fully diluted equity value of $104 million. The shares of the Company’s common stock issuable upon conversion of the Series G Preferred Stock shall be subject to stockholder approval in compliance with the rules of the Nasdaq Stock Market.

About Latiglutenase
Latiglutenase is an orally administered mixture of two minimally systemically absorbed gluten-specific recombinant proteases being developed as an oral biotherapeutic for celiac disease. In Phase 2a and 2b clinical trials, latiglutenase was shown to mitigate gluten-induced intestinal mucosal injury as well as reduce the severity and frequency of symptoms in celiac disease patients. The Phase 3 clinical development plan for latiglutenase has been reviewed by the GI Division of the U.S. Food and Drug Administration (FDA) at the End of Phase 2 meeting with an agreed plan forward, with initiation of the Phase 3 trials expected in 2025.

About Celiac Disease
Celiac disease is a chronic, hereditary autoimmune and inflammatory disease triggered by gluten consumption. Celiac disease is characterized by damage to the lining of the small intestine, causing malabsorption, gastrointestinal dysfunction, and debilitating symptoms. Over the course of a lifetime, untreated or poorly managed celiac disease is often associated with deteriorating general health, multiple serious intestinal and extra-intestinal medical complications, and increased morbidity and mortality. Celiac disease is a global disease and affects approximately 1% of the population worldwide and is increasing in prevalence with improved diagnostic tools and improved awareness.
