Centessa Pharmaceuticals Reports Financial Results for the Third Quarter of 2024 and Provides Business Update

•Announced additional interim data from ongoing Phase 1 clinical study of ORX750, a novel orexin receptor 2 (OX2R) agonist, in acutely sleep-deprived healthy volunteers that further support best-in-class potential of ORX750 in narcolepsy type 1 (NT1), narcolepsy type 2 (NT2), and idiopathic hypersomnia (IH); Presentation of Phase 1 data planned for medical congress in Q2 2025

•Initiated Phase 2a clinical study of ORX750 in patients with NT1, NT2 and IH; Phase 2a data across all three indications expected in 2025 with first-in-class potential in NT2 and IH

•Advancing ORX142 in IND-enabling studies for treatment of neurological, neurodegenerative, and psychiatric disorders; Clinical data in healthy volunteers planned for 2025

•Nominated ORX489 as third OX2R agonist development candidate; Entering IND-enabling studies for treatment of additional neurological, neurodegenerative, and psychiatric disorders

•Announced strategic decision to discontinue clinical development of SerpinPC; Net savings of approximately $200 million to be reallocated towards expansion of OX2R agonist franchise

BOSTON and LONDON, November 12, 2024: Centessa Pharmaceuticals plc (Nasdaq: CNTA), a clinical-stage

pharmaceutical company with a mission to discover, develop and ultimately deliver medicines that are

transformational for patients, today reported financial results for the third quarter ended September 30, 2024, and provided a business update.

“The totality of data across our OX2R agonist program continues to reinforce the strength of our discovery engine and the therapeutic potential of these assets across a broad spectrum of disorders,” said Saurabh Saha MD PhD, Chief Executive Officer of Centessa. “The Phase 1 interim data for ORX750, now updated to include over 70 subjects dosed with ORX750, continue to support its best-in-class potential in NT1, NT2 and IH. Based on the strength of these interim data, we recently initiated a Phase 2a clinical study of ORX750 in patients with NT1, NT2 and IH. Similar to our Phase 1 study, which enabled a move from IND clearance to clinical data in the course of a few months, we expect our Phase 2a study design to generate clinical data for all three indications in 2025 and enable dose selection for future pivotal studies with the potential to be first-in-class in NT2 and IH.”

Dr. Saha continued, “In addition to ORX750, we are advancing a growing pipeline of OX2R agonists targeting excessive daytime sleepiness (EDS) in neurological, neurodegenerative, and psychiatric disorders, as well as other potential symptoms including impaired attention, cognitive deficits, and fatigue. ORX142 is currently in IND-enabling studies, and subject to IND clearance, we expect to initiate clinical development and share clinical data in acutely sleep-deprived healthy volunteers in 2025. We’re also pleased to be kicking off our next wave of candidates with ORX489, our most potent OX2R agonist to date based on preclinical data, which is entering IND-enabling studies.”

Interim Data from Ongoing Phase 1 Clinical Study of ORX750

The additional interim data from the ongoing Phase 1 clinical trial of ORX750 in healthy volunteers includes results from two single-ascending dose (SAD) cohorts at 3.5 mg (n=12: 9 active, 3 placebo) and 5.0 mg (n=12: 9 active, 3 placebo), a cohort of acutely sleep-deprived healthy volunteers within the cross-over assessment at 3.5 mg (n=10) administered as a single oral dose, and two multiple-ascending dose (MAD) cohorts at 2.0 mg (n=10: 8 active, 2 placebo) and 3.0 mg (n=10: 8 active, 2 placebo). The interim data showed:

•Significantly increased wakefulness in acutely sleep-deprived healthy volunteers compared to placebo at all doses tested, with a clear dose dependent response. Treatment with ORX750 resulted in statistically significant (p<0.05) and clinically meaningful increased sleep latency in the Maintenance of Wakefulness Test (MWT) (time to sleep onset over the four sessions performed at ~2, 4, 6, and 8 hours after dosing at 11 p.m., maximum 40 minutes per session) compared to placebo at all doses tested. The 3.5 mg dose was shown to restore normative wakefulness1 with a mean sleep latency of 34 minutes and a placebo-adjusted mean sleep latency of 20 minutes, as measured by the MWT.

Interim Data from Ongoing Phase 1 Clinical Study of ORX750

(as of October 31, 2024 data cutoff date)

•A favorable safety and tolerability profile with all observed treatment-emergent adverse events (AEs) being mild and transient with none leading to treatment discontinuation. No cases of hepatotoxicity or visual disturbances were observed. Additionally, there were no clinically significant treatment-emergent changes in hepatic and renal parameters, vital signs, or electrocardiogram (ECG) parameters.

Interim Safety Data from Ongoing Phase 1 Clinical Study of ORX750

(as of October 31, 2024 data cutoff date)

Treatment-emergent adverse event (TEAE). Safety data from Sleep Study Cohorts was consistent with SAD. Nonrelated includes unlikely related and not related. Related includes probably and possibly related.

•An encouraging linear pharmacokinetic (PK) profile that supports the use of ORX750 as a once-daily oral dosing regimen with rapid absorption (plasma concentrations of ORX750 peaked 2h after the first dose). The systemic exposure of ORX750 increased in a dose-proportional manner.

The Phase 1 study is ongoing as dose escalation is continuing in the acutely sleep-deprived cross-over assessment, SAD and MAD portions of the study.

Phase 2a Clinical Study of ORX750

The Phase 2a study is a randomized, double-blind, placebo-controlled, cross-over basket study to evaluate the safety, tolerability, and PK of ORX750 in patients with NT1, NT2, and IH. There will be separate cohorts for each indication. Initial dosing for NT1 will be 1.0 mg and for NT2 and IH will be 2.0 mg with sequential dose escalation/

de-escalation between cohorts. Each dosing cohort consists of a 6-week treatment duration with crossover study design. During the 6 weeks of treatment, each participant will be randomized to one of two blinded treatment sequences and receive a total of 4 weeks of treatment with ORX750 and 2 weeks of treatment with placebo. Efficacy assessments will evaluate the effect of ORX750 on excessive daytime sleepiness (using the MWT and Epworth Sleepiness Scale (ESS)), cataplexy (NT1 patients only), and overall symptom improvement (measured by Narcolepsy Severity Scale (NSS) and Idiopathic Hypersomnia Severity Scale (IHSS)). Other exploratory assessments include measures of sleep, cognition, attention, memory, and general health.

“The Phase 2a study of ORX750 is intended to accelerate overall timelines and inform future registrational studies,” said Mario Alberto Accardi PhD, President of Centessa’s Orexin Program. “This well-powered study leverages highly innovative design elements which we believe have the potential to enable efficient data generation with an optimal number of patients in each indication. With this design, all participating patients will receive ORX750 for at least 4 weeks. We aim to generate data across all three indications in 2025, which could enable ORX750 to be first-in-class in NT2 and IH.”

SerpinPC Clinical Program Update

The Company has made a strategic and data-driven decision to discontinue the global clinical development of SerpinPC, a novel inhibitor of activated protein C that was being evaluated for the treatment of hemophilia B. This action was driven by the Company’s decision to prioritize capital toward the development of its OX2R agonist program and the outcome of a planned interim analysis of Part 1 of the PRESent-2 study of SerpinPC. Within the interim analysis, SerpinPC was observed to have a favorable safety and tolerability profile; however, the Company determined that additional time and investment would be required to further develop SerpinPC with a more

competitive profile for the treatment of hemophilia B in light of the evolving treatment and market landscape for hemophilia B, including the recent FDA approval of a competing product. The Company would like to thank the hemophilia community and all the patients, caregivers and physicians who participated in the SerpinPC clinical trials. The Company is now exploring potential strategic alternatives for SerpinPC.

“Moving forward, we intend to prioritize our resources and reallocate net savings of approximately $200 million associated with the planned commercial launch of SerpinPC towards expanding our potential best-in-class OX2R agonist franchise, where we see significant opportunities to both address unmet patient needs and create shareholder value,” stated John Crowley, Chief Financial Officer. “With a cash runway that extends into mid-2027, we believe Centessa is well positioned to support our OX2R agonist franchise through multiple, potential value-creating milestones.”

Recent Highlights

•In September, the Company presented preclinical data from non-human primate studies of ORX142 at the 27th Congress of the European Sleep Research Society (Sleep Europe 2024).

•In September, the Company completed an upsized underwritten public offering of 17,542,372 American Depositary Shares (ADSs) in the aggregate, at a price to the public of $14.75 per ADS, resulting in net proceeds of approximately $242.7 million, which included the underwriters’ over-allotment option to purchase additional shares.

•In September, the Company announced positive interim data from the ongoing Phase 1 clinical trial of ORX750 in acutely sleep-deprived healthy volunteers as of an August 26, 2024 data cutoff date.
