BOSTON and LONDON, November 13, 2023: Centessa Pharmaceuticals plc (Nasdaq: CNTA), a clinical-stage pharmaceutical company focused on discovering and developing medicines that are transformational for patients, today reported financial results and business highlights for the third quarter ended September 30, 2023.
“We continue to execute and achieve key milestones across our pipeline of potential transformative medicines for patients with unmet needs,” said Saurabh Saha MD PhD, Chief Executive Officer of Centessa. “We’re making good progress enrolling our registrational studies for SerpinPC in hemophilia B, with or without inhibitors, and are excited to share new data from the ongoing Phase 2a study of SerpinPC during a poster presentation at ASH in December. We also continue to advance our novel LockBody technology platform with LB101, a PD-L1xCD47 LockBody, which is in an ongoing Phase 1/2a clinical trial for the treatment of solid tumors.”
Dr. Saha continued, “Momentum continues to build with our orexin agonist development program. The preclinical data we recently shared at the World Sleep Congress show that ORX750 is a highly potent and selective novel orexin receptor 2 (OX2R) agonist that closely mimics the function of the endogenous peptide. We believe these data support a potential best-in-class profile for ORX750 for the treatment of narcolepsy and other sleep-wake disorders. We are focused on rapidly moving ORX750 through IND-enabling studies, obtaining IND clearance and initiating clinical development with the goal of sharing clinical proof of concept data in sleep-deprived healthy volunteers in 2024. In addition, we are exploring follow-up molecules for potential expansion opportunities into a range of sleep-wake disorders and broader neurological indications.”
Recent Highlights
•In October, the Company announced a set of new preclinical data from in vivo and in vitro studies of its investigational, novel OX2R agonist, ORX750, that support a potential best-in-class profile for the treatment of narcolepsy and other sleep-wake disorders. The preclinical data were presented recently at the World Sleep Congress and are also available within a recorded webcast at https://investors.centessa.com/events-presentations.
•In November, the Company announced that new data from the third year (Part 5) of the ongoing Phase 2a study of SerpinPC, an investigational subcutaneously administered novel inhibitor of activated protein C (APC), for the treatment of hemophilia, has been accepted for a poster presentation at ASH on December 10, 2023. The presentation will include efficacy and safety data from an additional 52-weeks of continuous treatment with a subcutaneous injection of SerpinPC in subjects with hemophilia.
•In October, the Company announced the dosing of the first subject in its registrational PRESent-3 clinical study of SerpinPC for the treatment of hemophilia B with inhibitors. The Company initiated dosing in its registrational PRESent-2 clinical study of SerpinPC for the treatment of hemophilia B without inhibitors in July.
•In August, the Company announced LB206, a PD-L1xCD3 LockBody, as a development candidate and shared preclinical data which demonstrated single agent regressions of large tumors in a difficult-to-treat mouse xenograft model.
Anticipated Upcoming Program Milestones
•Hemophilia (SerpinPC) - The registrational PRESent-2 and PRESent-3 studies are ongoing. Data from Part 5 of the ongoing Phase 2a study accepted for poster presentation at ASH on December 10, 2023.
•Solid Tumors (LockBody Technology Platform)
◦PD-L1xCD47 LockBody LB101 - Phase 1/2a first-in-human clinical study is ongoing.
◦PD-L1xCD3 LockBody LB206 - LB206 is a development candidate.
•Narcolepsy and Other Sleep-Wake Disorders (ORX750) - The Company is focused on rapidly advancing ORX750 through IND-enabling studies, obtaining IND clearance and initiating clinical development with the goal of sharing clinical proof of concept data in sleep-deprived healthy volunteers in 2024.
Where applicable, the Company plans to provide updates on preclinical programs as they advance toward clinical studies.
Third Quarter 2023 Financial Results
•Cash, Cash Equivalents and Short-term Investments: $281.3 million as of September 30, 2023, which the Company expects will fund operations into 2026, without drawing on the remaining available tranches under the Oberland credit facility.

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. The ongoing registrational program for SerpinPC in hemophilia B includes a set of clinical studies with multiple components. PRESent-5 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 or without inhibitors) and PRESent-3 (hemophilia B with inhibitors). Additional information on the trials can be accessed at www.clinicaltrials.gov (NCT05605678, NCT05789524, NCT05789537). The U.S. Food and Drug Administration (FDA) has granted Fast Track designation to SerpinPC for the treatment of hemophilia B, with or without inhibitors. SerpinPC is an investigational agent that has not been approved by the FDA or any other regulatory authority.
About the LockBody Technology Platform and LB101
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 tumor micro-environment (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 in a Phase 1/2a clinical trial. Additional information on the trial can be accessed at www.clinicaltrials.gov (NCT05821777). LB101 is an investigational agent that has not been approved by the FDA or any other regulatory authority.
About ORX750
ORX750 is an investigational, orally administered, highly potent and selective orexin receptor 2 (OX2R) agonist designed to directly target the underlying pathophysiology of orexin neuron loss in narcolepsy type 1 (NT1). ORX750 is Centessa’s first orexin product candidate being developed for the treatment of narcolepsy with potential expansion into other sleep-wake disorders. ORX750 is currently undergoing IND-enabling activities and has not been administered as an investigational drug to humans in any jurisdiction.
