BioNTech will hold exclusive licenses to develop and commercialize PM8002 globally excluding Greater China  

Biotheus Inc. ("Biotheus"), a clinical-stage biotech company dedicated to the discovery and development of biologics for oncology and inflammatory diseases,  announced that the company has entered into an exclusive global license and collaboration agreement under which BioNTech will be developing, manufacturing and commercializing PM8002 globally ex-Greater China, whereas Biotheus retains the rights to exploit PM8002 in Greater China. PM8002 is currently being tested in Phase 2 studies in China to evaluate the efficacy and safety of the candidate as a monotherapy or in combination with chemotherapy in patients with advanced solid tumors.

Under the terms of the agreement, Biotheus will receive an upfront payment of $55 million, and is eligible to receive additional development, regulatory and sales milestone payments potentially totalling over $1 billion as well as tiered royalties on potential future product sales. The transaction is expected to close in Q4 2023, subject to customary closing conditions, including clearance under the Hart-Scott-Rodino ("HSR") Antitrust Improvements Act, and regulatory clearances.

PM8002 is a bispecific antibody candidate with humanized anti-PD-L1 single heavy-chain variable (VHH) domains fused to an anti-VEGF-A IgG1 antibody containing Fc-silencing mutations. PM8002 has demonstrated a positive safety profile and encouraging antitumor activity presumably through reduced systemic toxicity by enriching anti-VEGF activity into the tumor microenvironment at this year's ASCO Annual Meeting and ESMO Congress 2023.

"Biotheus' innovative platform has the capability to expedite preclinical research, bolstering our impressive innovative pipeline of products with encouraging efficacy and safety including PM8002. Collaborating with industry trailblazer BioNTech, we hope to advance PM8002 through multi-regional clinical trials with the aim to be able to provide it to patients worldwide," stated Xiaolin Liu, Co-founder, Chairman, and CEO of Biotheus.
