Our programs span discovery-stage to late-stage development and cover a range of high-value indications.

We aim to pursue programs we believe could be first-in-class / best-in-class and where there is prior learning in human genetics or precedented human activity for a pathway of interest. We place a premium on learnings from our clinical trials, whereby a drug has established the relevance of a biological pathway contributing to disease outcome. Our approach is to pursue the best assets in a capital efficient manner and rapidly progress our programs through development, evaluating the unique biological advantage of our product candidates.

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  (NCT05605678, NCT05789524, NCT05789537). SerpinPC is an investigational agent that has not been approved by the FDA or any other regulatory authority.

LB101

Overview
Centessa’s proprietary LockBody technology platform aims to redefine immuno-oncology treatment for patients with cancer. LockBody drug candidates are designed to selectively drive potent effector function activity, such as CD47 or CD3, to the TME while avoiding systemic toxicity. The first LockBody candidate is LB101, a conditionally tetravalent PD-L1xCD47 bispecific monoclonal antibody which has two anti-CD47 domains blocked by two anti-PD-L1 domains, with proprietary human IgG-derived hinges linking the anti-CD47 and anti-PD-L1 domains. The cell-killing mechanism of action, CD47, is designed to be blocked by the PD-L1 tumor targeting domain until the IgG-derived hinges are naturally degraded in the TME, thus unlocking and activating the CD47 effector function activity in the tumor. LB101 is currently in a Phase 1/2a first-in-human trial. Additional information on the LB101 clinical trial can be accessed at www.clinicaltrials.gov. LB101 is an investigational agent that has not been approved by the FDA or any other regulatory authority.

LB206

Overview
We aim to develop novel therapeutics based on our unique LockBody® technology platform, which is designed to selectively drive potent effector function activity, such as CD47 or CD3, while avoiding systemic toxicity. The lead compound is LB101,  a conditionally tetravalent PD-L1xCD47 bispecific monoclonal antibody in a Phase 1/2a first-in-human trial. We recently named our second LockBody development candidate, LB206, a conditionally bivalent PD-L1xCD3 bispecific monoclonal antibody, which is designed to selectively drive potent CD3 effector function activity while avoiding systemic toxicity.

ORX750

Overview
We are developing ORX750, an oral selective orexin receptor 2 (OX2R) agonist designed to leverage unique structural insights and to directly target the underlying pathophysiology of orexin neuron loss in NT1 with potential expansion into other sleep disorders.
