German biotech giant BioNTech has acquired Chinese oncology startup Biotheus in a deal worth $950 million, expanding its oncology treatment portfolio and presence in China. Biotheus specializes in developing antibodies for oncological and inflammatory diseases, including BNT327/PM8002, a late-stage trial antibody product.
BioNTech plans to advance BNT327/PM8002, which has shown promising results in treating various tumor types. The antibody has demonstrated a positive safety profile and notable antitumor activity, particularly in non-small cell lung cancer and triple-negative breast cancer when combined with chemotherapy. Future trials will explore integrating the antibody with BioNTech’s proprietary antibody-drug conjugates.
Ugur Sahin, BioNTech’s CEO, highlighted the therapy’s potential to exceed traditional checkpoint inhibitors in multiple oncology indications. “We aim to combine this with our mRNA vaccines and targeted therapies to enhance outcomes for patients with solid tumors,” Sahin said.
The acquisition grants BioNTech access to Biotheus’ biologics manufacturing facility and a 300-strong R&D team, boosting its innovation capacity. Biotheus CEO Xiaolin Liu emphasized the potential of their discovery platform and pipeline of investigational assets.
The move aligns with BioNTech’s strategic expansion in the fast-growing Chinese biotech sector, joining global players like Pfizer, GSK, and Sanofi. BioNTech’s $25 million investment in MediLink’s solid tumor-focused ADC further underlines its regional commitment. This acquisition positions BioNTech to strengthen its oncology research and clinical capabilities, leveraging Biotheus’ innovative approaches to antibody development.
