invoX Pharma Completes Acquisition of F-star Therapeutics, Inc.

invoX Pharma Limited (“invoX”), a U.K.-based wholly-owned subsidiary of Sino Biopharmaceutical Limited (“Sino Biopharm”) (HKEX 1177 HK) with an advancing pipeline of innovative products, today announces that it has successfully completed the acquisition of F-star Therapeutics, Inc. (“F-star”) (NASDAQ:FSTX), a clinical-stage biopharmaceutical company pioneering bispecific antibodies in immunotherapy, for an aggregate cash consideration of approximately $161 million (or $7.12 per share).

F-star is currently executing Phase 2 trials in Europe and the U.S. in patients with PD-1 acquired resistant head and neck cancer, and in checkpoint inhibitor-naïve patients with non-small cell lung cancer (NSCLC) and diffuse large B-cell lymphoma (DLBCL). The Company also has further earlier clinical studies underway with patients in both geographies.

All required regulatory approvals for closing of the transaction have been obtained, including clearance from the regulatory agency in charge of enforcing the U.K.’s National Security and Investment Act and the Committee on Foreign Investment in the United States (“CFIUS”).

Ben Toogood, Chief Executive Officer of invoX, commented:

“The closing of the transaction today significantly strengthens invoX’s pharmaceutical business, accelerating the build of a pipeline with a core focus on oncology and respiratory therapeutics. Most importantly, it provides the capital to ensure patients enrolled in F-star’s clinical studies will continue to have access to potentially life-saving therapies.

‘We are pleased to have reached agreement with regulators in the U.S. following substantial and thorough discussion. This clearance is a clear signal that governments recognize the importance of collaboration among trusted parties to advance patient-centered innovations in biotechnology.

‘We believe this will lay a solid foundation and understanding for our steps into the future and leaves us well positioned to continue to grow worldwide through further investment opportunities. We are also excited to welcome F-star employees and look forward to working with them as we invest in the company to progress and grow its clinical pipeline to realize the full potential of the platform.”
