Biodexa Announces Successful Outcome of a Type C Meeting with FDA Regarding the Phase 3 Program for eRapa in FAP

Clears the way to finalize Phase 3 protocol and recruit sites for U.S.

Phase 3 substantially funded by $17.0 million CPRIT grant and $8.5 million Company match

Biodexa Pharmaceuticals PLC (“Biodexa” or the “Company”) (Nasdaq: BDRX), a clinical stage biopharmaceutical company developing a pipeline of innovative products for the treatment of diseases with unmet medical needs, today announced the results of its Type C meeting with the U.S. Food and Drug Administration (“FDA”) regarding the protocol for the planned registrational Phase 3 study of eRapa in familial adenomatous polyposis (“FAP”).

The Type C meeting followed a productive End of Phase 2 meeting with FDA and the publication of Phase 2 data of eRapa in FAP at six months at Digestive Disease Week in May 2024 and 12 months data at InSight, Barcelona in June 2024. The Type C meeting included a discussion of the statistical plan, the safety database and, most importantly, a composite endpoint for the Phase 3 study. FDA representatives from both Gastroenterology and Oncology Divisions provided valuable input into the proposed program and the Company believes there is a clear path forward for initiation of the registrational Phase 3 study in FAP in the U.S. next quarter.

The planned registrational Phase 3 study of eRapa in FAP will be a double-blind placebo-controlled trial in 168 patients, randomized 2:1 drug / placebo. It is expected the study will be conducted in approximately 30 clinical sites across the US and Europe. The US component of the study will be conducted by LumaBridge, based in San Antonio, Texas and the European component will be conducted by Precision for Medicine LLC. The Phase 3 study is supported by a $17.0 million grant from the Cancer Prevention Research Institute of Texas (“CPRIT”) and a Company match of $8.5 million which has already been paid, in full, into escrow.

Commenting, Dr Gary Shangold, Chief Medical Officer of Biodexa, said, “With no approved products for FAP, we were pleased to collaborate with FDA and our US CRO, LumaBridge, to define the regulatory pathway for eRapa in FAP. Agreement on the composite endpoint, in particular, clears the path to finalize the protocol, recruit the U.S. sites and begin patient enrolment”

About eRapa

eRapa is a proprietary oral tablet formulation of rapamycin, also known as sirolimus. Rapamycin is an mTOR (mammalian Target Of Rapamycin) inhibitor. mTOR has been shown to have a significant role in the signalling pathway that regulates cellular metabolism, growth and proliferation and is activated during tumorgenesis3. Importantly, mTOR has been shown to be over-expressed in FAP polyps – thereby underscoring the rationale for using a potent and safe mTOR inhibitor like eRapa to treat FAP. Rapamycin is approved in the US for organ rejection in renal transplantation as Rapamune®(Pfizer). Through the use of nanotechnology and pH sensitive polymers, eRapa is designed to address the poor bioavailability, variable pharmacokinetics and toxicity generally associated with the currently available forms of rapamycin. Data from the Phase 2 study showed eRapa to be safe and well-tolerated with a median 17% reduction in total polyp burden at 12 months compared with baseline and an overall 75% non-progression rate. Patients in cohort 2 experienced an 89% non-progression rate and 29% median reduction in polyp burden at 12 months compared with baseline. The dosing given to cohort 2 – daily every other week -- is the dosage regimen to be used in the upcoming registrational Phase 3 study.
