BOSTON and LONDON, March 30, 2022 (GLOBE NEWSWIRE) -- Centessa Pharmaceuticals plc (Nasdaq: CNTA), a clinical-stage pharmaceutical company with a Research & Development (“R&D”) innovation engine that aims to discover, develop and ultimately deliver impactful medicines to patients, today reported financial results for the fourth quarter and year ended December 31, 2021 and provided a business update.

“We have strengthened our strategic focus on innovative, high impact rare disease and immuno-oncology assets. Lixivaptan for ADPKD and SerpinPC for hemophilia are entering into registrational studies while LB101, our PD-L1xCD47 LockBody®, is advancing toward the clinic,” said Saurabh Saha, MD, PhD, Chief Executive Officer. “We are in a strong financial position to make significant clinical progress towards our ‘4x24’ goal of having four programs in registrational trials in 2024.”

“We believe that our LockBody® programs have the potential to become the cornerstone for a multi-product immuno-oncology franchise. We look forward to sharing initial preclinical data at ASCO 2022 for the first program, LB101, which is designed to selectively drive potent CD47 effector function activity while avoiding systemic toxicity,” said Antoine Yver, MD, MSc, Chairman of Development.

“The breadth of our rare disease programs provides us multiple opportunities to develop drugs which can potentially impact the lives of thousands of patients living with debilitating diseases such as ADPKD, hemophilia, alpha-1-antitrypsin deficiency, pulmonary arterial hypertension, and narcolepsy, among others,” added Javad Shahidi, MD, MSc, Chief Medical Officer.

2021 Highlights and Recent Business Updates

Clinical Development Updates

  • SerpinPC: Recently completed pre-IND interactions with the FDA regarding the planned registrational studies for SerpinPC. Based on the FDA feedback, the Company is proceeding with a streamlined, integrated registrational development plan initially for Hemophilia B, with and without inhibitors. The FDA discussions followed the announcement in September 2021 of positive topline data from a proof-of-concept study of SerpinPC in severe Hemophilia A and B subjects not on prophylaxis.
  • Lixivaptan: Commenced dosing in the pivotal Phase 3 clinical trial (“ACTION Study”) evaluating lixivaptan as a potential treatment for autosomal dominant polycystic kidney disease (“ADPKD”). In addition, a key US patent was issued on February 8, 2022, which covers the use of lixivaptan for the treatment of ADPKD. The patent term expires June 8, 2038, before considering possible patent term extensions or adjustments. 
  • ZF874: Announced proof-of-mechanism data from the first three PiMZ subjects dosed in the Phase 1 Part B study evaluating ZF874 for the treatment of AATD demonstrating that a pharmacological chaperone has the potential to achieve clinically significant Z-A1AT serum increases in individuals with AATD.

Business Updates

  • Further strengthened the leadership team with multiple key appointments, including Antoine Yver, MD, MSc, Executive Vice President and Chairman of Development; Javad Shahidi, MD, MSc, Chief Medical Officer; and David Grainger, PhD, Chief Innovation Officer.
  • Dosing of the first subject with lixivaptan in the Phase 3 ACTION Study in February 2022 triggered settlement of the contingent value rights (“CVRs”) originally issued to the former shareholders and option holders of Palladio Biosciences in connection with its acquisition by Centessa in January 2021.
  • Entered into financing agreement with funds managed by Oberland Capital Management LLC (“Oberland Capital”) and received initial $75 million funding in October of 2021.
  • As part of ongoing portfolio management, the Company has recently decided to discontinue the small molecule EGFR inhibitor discovery program; evaluate strategic options, including potential divestment, for imgatuzumab; and discontinue internal funding for the lead dual-STAT3/5 degrader program.
  • Announced ‘4x24’ portfolio goal with the aim of having four registrational programs in 2024.

Upcoming Program Milestones

Registrational: Programs currently in or expected to enter registrational trials this year:

  • Lixivaptan, vasopressin V2 receptor antagonist for ADPKD: Lixivaptan is currently being administered in the Phase 3 registrational ACTION Study to investigate its potential to treat ADPKD and avoid safety issues associated with the only drug currently approved for the treatment of ADPKD. The ACTION Study is expected to enroll ~1,350 subjects across >200 sites in over 20 countries. The Company anticipates completing enrollment in the second half of 2023 and, if results are supportive, plans to submit a New Drug Application after completion of the one-year double-blind portion of the study.
  • SerpinPC, an activated protein C inhibitor for Hemophilia: In the second half of 2022 the Company expects to launch two registrational studies. The first study will enroll ~120 subjects and evaluate the efficacy and safety of prophylactic SerpinPC in subjects with severe Hemophilia B without inhibitors and will include subjects with severe Hemophilia A to add to the safety database. The second registrational study is planned with fewer than 20 subjects to evaluate the efficacy and safety of SerpinPC in subjects with severe Hemophilia B with inhibitors. Registrational plans for Hemophilia A are in development. The Phase 2a open label extension study is ongoing, and we expect to report data on the 48-week flat dose portion of that study and interim results from the following 24-week high dose portion in the fourth quarter of 2022.

Emerging: Programs / platforms with expected clinical proof of concept in the next 18 months

  • LB101 and LB201 in Solid Tumors: LB101, a PD-L1xCD47 LockBody®, is designed to selectively drive potent CD47 effector function activity while avoiding systemic toxicity. We anticipate sharing foundational preclinical data at ASCO 2022, with an IND for LB101 planned for late 2022. LB201, a PD-L1xCD3 LockBody®, is designed to selectively drive potent CD3 effector function activity while avoiding systemic toxicity. IND for LB201 is planned for 2023.
  • ZF874 in Alpha-1 Antitrypsin Deficiency (AATD): Small molecule folding corrector of the Z variant of alpha-1-antitrypsin. We expect to share Phase 1 data from multiple dose cohorts with PiMZ and PiZZ subjects in 2H 2022.
  • MGX292 in Pulmonary Arterial Hypertension (PAH): Recombinant modified BMP9 replacement protein designed to overcome the deficiency in BMP9 signaling in PAH. IND is planned for early 2023.
  • OX2R Agonists (Oral and Intranasal) in Narcolepsy Type 1 (NT1): Selective orexin receptor 2 agonists targeting the underlying pathophysiology of orexin neuron loss in NT1. INDs/CTAs are planned for 2023.

Exploratory: Programs with expected clinical proof of concept beyond 18 months

  • CBS001 in Inflammatory / Fibrotic Diseases: High-affinity anti-LIGHT antibody. Phase 1 clinical trial in healthy volunteers is expected to begin in the second quarter of 2022.
  • CBS004 in Autoimmune Diseases: Humanized mAb targeting BDCA2. IND is planned for late 2022.

Fourth Quarter and 2021 (period January 30 through December 31, 2021) Successor Financial Results

  • Cash and Cash Equivalents: $595.1 million as of December 31, 2021 which the Company expects will fund operations, based on current non-risk adjusted plans, into early 2024, without drawing on the remaining available tranches under the Oberland facility.
  • R&D Expenses: $41.5 million for the Company for the quarter ended December 31, 2021, $95.7 million for the Successor for 2021.
  • General & Administrative Expenses: $13.0 million for the Company for the quarter ended December 31, 2021, $42.9 million for the Successor for 2021.
  • Net Loss Attributable to Ordinary Shareholders: $60.8 million for the quarter ended December 31, 2021, $381.1 million for the Successor for 2021 (which includes two special, non-cash expenses: a $220 million charge for acquired in-process R&D associated with the Centessa subsidiary acquisitions; and a $15 million fair value adjustment to the CVRs).
