Centessa Pharmaceuticals Receives Fast Track Designation from the U.S. FDA for SerpinPC for Hemophilia B

BOSTON and LONDON, May 22, 2023 (GLOBE NEWSWIRE) -- Centessa Pharmaceuticals plc (Nasdaq: CNTA), a clinical-stage pharmaceutical company that aims to discover and develop medicines that are transformational for patients, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to SerpinPC, an investigational novel inhibitor of activated protein C (APC) being developed for the treatment of hemophilia B, with or without inhibitors. 

"We are pleased with the FDA’s decision to grant Fast Track designation for SerpinPC as we continue to advance the PRESent registrational studies for SerpinPC in hemophilia B,” said Saurabh Saha MD PhD, Chief Executive Officer of Centessa. “This designation is important recognition of SerpinPC’s novel mechanism of action and underscores the critical need for new treatment options for persons with hemophilia B. We believe SerpinPC has the potential to be a first-in-class subcutaneously administered therapy with a differentiated safety profile for persons with hemophilia B, subject to review and approval.”

According to the FDA, Fast Track is a process designed to facilitate the development and expedite the review of drug candidates to treat serious conditions and fulfill an unmet medical need. A therapeutic candidate that receives Fast Track designation may be eligible for more frequent interactions with the FDA to discuss the candidate’s development plan and, if relevant criteria are met, eligibility for Accelerated Approval, Priority Review, or Rolling Review.

About SerpinPC
SerpinPC is a subcutaneously administered novel inhibitor of APC being developed as a potential treatment for hemophilia, regardless of severity or inhibitor status, and which may also be developed to prevent bleeding associated with other bleeding disorders. Centessa is advancing the registrational program for SerpinPC in hemophilia B, which includes a set of clinical studies with multiple components. PRESent-5, initiated in late 2022, is an observational feeder study to collect prospective observational data for minimum defined periods before switching to dosing subjects in the interventional studies. The interventional studies include PRESent-2 (moderately severe to severe hemophilia B without inhibitors, and severe hemophilia A with and without inhibitors) and PRESent-3 (hemophilia B with inhibitors). Additional information on the trials can be accessed at www.clinicaltrials.gov (NCT05605678, NCT05789524, NCT05789537). SerpinPC is an investigational agent that has not been approved by the FDA or any other regulatory authority.
