CAMBRIDGE, Mass. & LONDON, August 16, 2021 – Centessa Pharmaceuticals plc (Nasdaq: CNTA), a clinical-stage company leveraging its innovative asset-centric business model to discover, develop and ultimately deliver impactful medicines to patients, today reported financial results for the quarter ended June 30, 2021, and provided a review of recent accomplishments and anticipated upcoming milestones.

“Centessa has made significant progress since launch and completion of our $250 million Series A financing in January,” said Saurabh Saha, M.D., Ph.D., Chief Executive Officer of Centessa. “The successful execution of our upsized initial public offering in the second quarter has substantially enhanced our resources and will support the advancement of our broad portfolio of assets across our 10 subsidiary companies. This added capital, together with the appointment of exceptional industry leaders in key functional areas across the organization, positions us for continued success. We look forward to sharing our progress, including a planned Phase 2a data update from ApcinteX in the coming weeks.”

Business Updates

$379.5 Million Initial Public Offering (IPO) Successfully Completed: In the second quarter, Centessa closed its initial public offering of 16,500,000 American Depositary Shares (ADSs). In addition, the underwriters fully exercised their option to purchase an additional 2,475,000 ADSs at the IPO price of $20.00 per ADS, less underwriting discounts and commissions. The gross proceeds to Centessa from its IPO, before deducting underwriting discounts, commissions and other estimated offering expenses, totaled an aggregate of $379.5 million.

Leadership Team Strengthened by Appointment of Key Industry Executives: In May, Centessa announced the leadership appointments of Antoine Yver, M.D., M.Sc., Chief Medical Officer; Tia Bush, Chief Quality Officer; David Chao, Ph.D., Chief Administrative Officer; and Thomas Templeman, Ph.D., Chief Technology Officer. In addition, Marella Thorell was promoted to Chief Accounting Officer, and Carol Stuckley joined the Board of Directors, serving as Chairperson of the Audit Committee. Each of these leaders provides significant expertise in their respective functions and will help drive execution across the Company’s portfolio of programs.

Program Updates and Upcoming Milestones in the Second Half of 2021

Topline Phase 2a data from ApcinteX’s 24-week repeat dose study evaluating SerpinPC in hemophilia A (HA) and hemophilia B (HB) patients
SerpinPC, a first-in-class coagulation rebalancing agent, is a specific inhibitor of activated protein C (APC) being evaluated as a monthly subcutaneous therapeutic for HA and HB patients that has the potential to significantly reduce bleeding rates.


The Phase 2a has completed dosing and the Company anticipates sharing topline results in the third quarter of 2021.
All subjects who have completed the 24-week repeat dose portion of the study have elected to roll-over into a long-term open-label extension study.

Start-up activities have begun for the ACTION Study, Palladio Biosciences' global Phase 3 registrational study of lixivaptan in autosomal dominant polycystic kidney disease (ADPKD)
Lixivaptan, a vasopressin V2 receptor antagonist, is being investigated as a potential best-in-class therapy in patients with ADPKD.
The Company anticipates dosing the first patient in the registrational ACTION Study in the first quarter of 2022.
The Company expects to report ongoing safety data from the initial subjects in the open-label ALERT Study of patients who previously discontinued JYNARQUE® (tolvaptan) due to liver toxicity in the fourth quarter of 2021.

Phase 1 data from Z Factor’s study evaluating ZF874 for the treatment of alpha-1-antitrypsin deficiency (AATD)
ZF874, a small molecule folding corrector of the Z variant of alpha-1-antitrypsin, is designed to increase serum levels of alpha-1-antitrypsin and reduce liver polymer burden to treat or prevent associated lung and liver disease manifestations associated with AATD.
The Company anticipates providing an update from an ongoing 28-day repeat dose Phase 1 study in subjects with PiXZ genotype by the end of 2021.

Phase 2 trial initiation with Pega-One’s imgatuzumab in advanced cutaneous squamous cell carcinoma (CSCC)
Imgatuzumab, a non-fucosylated epidermal growth factor receptor (EGFR) targeting monoclonal antibody (mAb), is being investigated as a next-generation EGFR agent with enhanced Antibody-Dependent Cellular Cytotoxicity (ADCC) and Antibody-Dependent Cellular Phagocytosis (ADCP) properties to potentially address CSCC.
The Company expects to initiate an open label, single arm, Phase 2 trial of imgatuzumab in advanced CSCC by the end of 2021.

Second Quarter 2021 Financial Results

Cash Position: Cash and cash equivalents were $613.8 million as of June 30, 2021, compared to $7.2 million for the Centessa Predecessor Group (comprised of Z Factor Limited, LockBody Therapeutics Ltd, and Morphogen-IX Limited, three of the Centessa Subsidiaries acquired in January 2021) as of December 31, 2020. The increase in cash resulted from $344.1 million in net proceeds from the Company’s initial public offering completed in June 2021, and the full exercise of the underwriters’ option to purchase additional shares, $241.6 million in net proceeds from the Company’s Series A financing completed in January 2021, and cash contributed upon the acquisition of the additional Centessa Subsidiaries, net of cash used during the period. Based on the current, non-risk-adjusted operating plan, the Company expects the cash and cash equivalents as of June 30, 2021, to fund its operations until the end of 2023.

Research & Development (R&D) Expenses: R&D expenses for the Company for the three months ended June 30, 2021, were $18.1 million, compared to $1.9 million for the Centessa Predecessor Group during the three months ended June 30, 2020. The $16.2 million increase is primarily attributable to the growth in the portfolio of product candidates under development following the acquisition of the Centessa Subsidiaries in January 2021, as well as increased spending in the Centessa Predecessor Group.

General & Administrative (G&A) Expenses: G&A expenses for the Company for the three months ended June 30, 2021. were $11.8 million, compared to $0.3 million for the Centessa Predecessor Group during the three months ended June 30, 2020. The $11.5 million increase is primarily attributable to public company costs, the operating costs of Centessa Pharmaceuticals plc and Centessa Pharmaceutical Inc. including professional fees, personnel costs and share-based compensation expense, and the increase in operating costs resulting from the acquired Centessa Subsidiaries.

Change in Fair Value of Contingent Value Rights (CVR): The Company recognized a charge of $11.3 million for the three months ended June 30, 2021, compared to $0.0 million for the three months ended June 30, 2020. The CVR, issued at the time of the acquisition, represents future payments (that will be satisfied through the issuance of Centessa shares) that are contingent upon the dosing of the first patient in a registrational Phase 3 study of Palladio Biosciences’ lixivaptan. The fair value is based on the cumulative probability of achieving this milestone, which increased during the period resulting in the charge.

Net Loss: Net Loss attributable to common stockholders for the quarter ended June 30, 2021, was $41.5 million, or $0.65 per share, compared to a net loss of $2.2 million for the Centessa Predecessor Group for the quarter ended June 30, 2020.
