With Fast Track Designation in Hand, a Successful Protocol Discussion with FDA, and CROs in Place, Biodexa is on Track to Initiate its Funded Phase 3 Trial in FAP Next Quarter

CARDIFF, UNITED KINGDOM / ACCESS Newswire / March 19, 2025 / Biodexa Pharmaceuticals PLC. (NASDAQ:BDRX), a clinical stage biopharmaceutical company developing a pipeline of innovative products for the treatment of diseases with unmet medical needs, is making progress in readying the launch of a phase 3 trial for eRapa, its proprietary encapsulated form of rapamycin being developed for the treatment of familial adenomatous polyposis (FAP).

In just the last few weeks, Biodexa received Fast Track designation from the FDA, conducted a successful Type C (pre-Phase 3 protocol finalization) meeting with the FDA and appointed a clinical research organization (CRO) to conduct the European component of its registrational Phase 3 trial. A CRO for the U.S. component was appointed earlier.

FAP is an inherited condition that puts people at a much greater risk of developing colon cancer. With FAP, hundreds or thousands of precancerous polyps grow throughout the gastrointestinal tract. There is no approved therapeutic option for treating FAP patients, for whom active surveillance and surgical resection of the colon and/or rectum remain the standard of care. People with FAP, which usually appears in the patient's mid-teens, end up eventually having their entire colon removed. If left untreated there is a high likelihood the person will develop colon or rectum cancer.

Biodexa hopes to help with eRapa, a proprietary oral tablet formulation of rapamycin, also known as sirolimus, which slows down the mTOR (mammalian Target Of Rapamycin) protein.

"Too much mTOR has been linked to cancer and has been shown to be over-expressed in FAP polyps - thereby underscoring the rationale for using an mTOR inhibitor like eRapa to treat FAP", noted Stephen Stamp, Biodexa's CEO and CFO.

Phase 3 Study Commencing Next Quarter

Biodexa, which has already received Fast Track designation by the FDA for the drug, completed a successful Phase 2 trial of eRapa, demonstrating a 17% median decrease in overall polyp burden and an overall non-progression rate of 75%. Biodexa said patients in cohort 2, the dosage regimen that will be used in Phase 3, experienced an 89% non-progression rate and 29% median reduction in polyp burden at 12 months compared with baseline.

The Phase 3 study will be a double-blind placebo-controlled design recruiting approximately 168 high-risk patients diagnosed with germline or phenotypic FAP. It is expected the study will be conducted in about 30 clinical sites across the U.S. and Europe.

That Phase 3 trial is getting closer to a launch following on the heels of what the company says was a successful Type C meeting with the FDA. During the meeting with FDA representatives from both the gastroenterology and oncology divisions, Biodexa and the FDA discussed the company's statistical plan, the safety database and a composite endpoint for the Phase 3 study. As a result of that meeting, Biodexa believes it has a clear path forward for the initiation of the U.S. Phase 3 study next quarter.
