Key Takeaways
- BioNTech and BMS Join Forces on Bispecific Antibody BNT327
The two pharma giants have entered into a global partnership to co-develop and co-commercialize BNT327, a next-generation bispecific antibody targeting PD-L1 and VEGF-A for multiple solid tumors.
- $3.5 Billion Investment with Up to $7.6 Billion in Milestones
BMS will pay $1.5 billion upfront and $2 billion in non-contingent payments through 2028, with potential milestone payments bringing the total deal value to $11.1 billion.
- BNT327 Positioned as a Foundational Immuno-Oncology Asset
Currently in Phase III trials for lung cancers, with a triple-negative breast cancer trial slated for 2025, BNT327 is being explored in 20-plus studies and may serve as a future IO backbone in combination with antibody drug conjugates and mRNA-based therapies.
Bristol Myers Squibb (BMS) and BioNTech have announced a global strategic partnership to co-develop and co-commercialize BNT327, BioNTech’s bispecific antibody candidate targeting multiple solid tumor types. BNT327, which targets PD-L1 and VEGF-A, is currently in advanced clinical trials, including global Phase III trials for the first-line treatment of extensive-stage small cell lung cancer (ES-SCLC) and non-small cell lung cancer (NSCLC), with a trial in triple-negative breast cancer (TNBC) expected to begin by the end of 2025. Preliminary data indicate that combining these two established targets in a single molecule could offer synergistic benefits across several tumor types.
What Makes BNT327 a Potential Game-Changer in Oncology?
Under terms of the deal, BMS will make an upfront payment of $1.5 billion to BioNTech and commit an additional $2 billion in non-contingent payments through 2028, with potential milestone payments reaching up to $7.6 billion. Development, manufacturing, and global profits will be equally shared.1
"We believe BNT327 has the potential to become a foundational immuno-oncology backbone, moving beyond single-mechanism checkpoint inhibitors and expanding into multiple solid-tumor indications,” said Ugur Sahin, MD, CEO, co-founder, BioNTech, in a press release. “Our collaboration with BMS, a pioneering leader in immuno-oncology, aims to accelerate and broadly expand BNT327’s development to fully realize its potential. Our focus remains on advancing high-impact, pan-tumor programs and combination strategies in oncology, with BNT327 complementing our antibody-drug conjugate programs and mRNA-based immunotherapies. We are dedicated to delivering truly transformative options for patients in need."
Bispecific Antibodies Gain Momentum in Pharma
The deal comes amid an increased interest in bispecific antibodies that simultaneously inhibit immune checkpoints and tumor angiogenesis. Last month, Pfizer announced a $6 million agreement with 3SBio to develop, manufacture, and commercialize SSGJ-707, an additional bispecific antibody targeting PD-1 and VEGF pathways. According to Pfizer, the treatment has shown promise in NSCLC, metastatic colorectal cancer, and gynecological malignancies.
Recent Acquisitions and Competitive Landscape
In November 2024, BioNTech acquired Biotheus for $800 million. Under terms of that deal, BioNTech obtained the rights to BNT327/PM8002, a bispecific antibody that also targets PD-L1 and VEGF.
