BOCA RATON, Fla., July 31, 2024 (GLOBE NEWSWIRE) -- Entero Therapeutics, Inc., (NASDAQ: ENTO), (“Entero Therapeutics” or the “Company”), a clinical-stage biopharmaceutical company specializing in the development of targeted, non-systemic therapies for gastrointestinal (GI) diseases, today released a letter from James Sapirstein, the Company’s Chairman and CEO, to provide stockholders with a business update.

LETTER FROM OUR CHAIRMAN AND CHIEF EXECUTIVE OFFICER

To my fellow stockholders,

We are making substantial progress in the development and on the regulatory pathways with our lead product candidate, latiglutenase, a late-stage clinical asset for the treatment of celiac disease. Our primary focus is on advancing latiglutenase into a pivotal Phase 3 trial in 2025. Our recent regulatory agency interactions and operational changes outlined below reflect our sharp focus on positioning Entero for success with this lead program that can potentially address the unmet treatment needs for the millions of people currently struggling with celiac disease.

After reviewing previous results from the Phase 2b clinical trial of latiglutenase, we decided to submit two Type D meeting requests to the FDA to build a more precise and efficient Phase 3 clinical trial design and development plan for latiglutenase.

The first meeting request seeks approval to change the number of proposed cohorts in the latiglutenase Phase 3 trial from three (600 mg, 1200 mg and placebo) to two (1200 mg and placebo). Since the safety of 1200 mg of latiglutenase has been shown to be comparable to lower doses in previous Phase 2 trials, we believe the higher dose will maximize the efficacy of latiglutenase and provide us with the greatest potential to achieve success in the primary endpoint and key secondary endpoints. This adjustment should reduce the number of patients required for a Phase 3 trial and has the potential to both lower its estimated cost and shorten the time to an interim data read-out and trial completion by several months.

We also plan to submit a second Type D meeting request in the next few weeks to finalize our histology-related secondary efficacy endpoints based on previous FDA communications and recent Phase 2 study results demonstrating statistically significant histologic improvements relative to placebo using the highest doses of latiglutenase.

Additionally, we are preparing a response to the most recent end of Phase 2 and Type C meeting correspondence with the FDA to propose an updated protocol and streamlined trial design with the single-dose regimen and a focus on the most severe and symptomatic patient population demonstrating intestinal damage. These modifications are designed to expedite and maximize the potential success of the Phase 3 clinical trial.
