Who We Are

Centessa is a transformational pharmaceutical company.

At Centessa, we discover and develop medicines that are transformational for patients. We operate our clinical research with the conviction that each one of our programs has the potential to change the current treatment paradigm and establish a new standard of care. We aim to achieve this patient-centric mission with a focus on developing a portfolio of highly innovative assets, unconstrained by therapeutic area or technology.

Centessa’s core medical research operating principle is to make timely, unbiased decisions driven by data and biology. We focus on making the best decisions for each asset without constraints or bias stemming from the needs of other programs in the portfolio. We are confident this unencumbered, asset-centric philosophy has the potential to deliver significant value for all stakeholders.

SerpinPC

Overview
SerpinPC is a subcutaneously administered novel inhibitor of APC being developed as a potential treatment for hemophilia, regardless of severity or inhibitor status, and may also 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  (NCT05605678NCT05789524NCT05789537). SerpinPC is an investigational agent that has not been approved by the FDA or any other regulatory authority.
