First Wave BioPharma Announces Invited Paper for Special Edition on Celiac Disease in Peer-Reviewed Scientific Journal, Nutrients

Paper highlights findings on impact of a gluten-containing diet on serologic status in celiac disease

BOCA RATON, Fla., April 24, 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 research generated from two previously completed Phase 2 clinical trials of latiglutenase has been published in the special issue "Recent Advances in Gluten-Free Diet and Celiac Disease" in the peer-reviewed scientific journal, Nutrients. Latiglutenase, an oral biotherapeutic composed of two gluten-specific recombinant proteases, is a potentially first-in-class, targeted, oral biotherapeutic for celiac disease (CeD).

The featured paper is entitled “Dynamics of Serologic Change to Gluten in Celiac Disease Patients” ( The manuscript benefits from one of the largest databases of CeD clinical results from several Phase 2 clinical trials for latiglutenase and addresses two issues: (i) the return to seropositivity for CeD patients who resume a gluten containing diet for diagnostic purposes and (ii) the correlation between two different tTG-IgA assays at their defined upper limit of normal (ULN) thresholds.

“Our focus on developing latiglutenase is bolstered by this groundbreaking CeD research, just one component of the scientific, clinical, and regulatory expertise in gastroenterological drug development that Jack Syage and his team, formerly from ImmunogenX, bring to First Wave,” stated James Sapirstein, Chairman and CEO of First Wave. “The potential for latiglutenase to transform treatment is backed by solid data from these Phase 2 trials, which have shown latiglutenase to be safe, well-tolerated, and effective at breaking down the gluten proteins that lead to intestinal damage and the symptoms of celiac disease.”

“The research published in Nutrients highlights new tools that may serve as critical diagnostics for identifying seroactive patients and for monitoring the efficacy of latiglutenase,” stated Jack Syage, Ph.D. President & Chief Scientific Officer, First Wave BioPharma. “The evidence produced from this rich deposit of clinical data advances not only the development of latiglutenase but also benefits the whole field of celiac disease research in order to bring needed relief to the millions who suffer from this disease.”

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 reduce the severity and frequency of symptoms as well as mitigate gluten-induced intestinal mucosal injury 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 early 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.
