MAINZ, Germany and SHANGHAI, China, April 3, 2023 – BioNTech SE (Nasdaq: BNTX, “BioNTech”) and Duality Biologics (Suzhou) Co. Ltd. (“DualityBio”), a clinical-stage biotech company focusing on the discovery and development of next generation antibody-drug conjugate (“ADC”) therapeutics to treat patients with cancer and autoimmune diseases, today announced that the companies have entered into exclusive license and collaboration agreements for two ADC assets to develop, manufacture and commercialize the two assets globally, excluding Mainland China, Hong Kong Special Administrative Region and Macau Special Administrative Region. With this collaboration, ADCs will become an additional drug class in BioNTech’s oncology portfolio with the aim to further support BioNTech’s mission of developing highly efficacious therapies for cancer patients at every stage of disease.
ADCs are a class of potent cancer therapies combining the selectivity of antibodies with the potent cell-killing properties of chemotherapy or other anti-cancer agents.
As part of the collaboration, BioNTech will gain access to DualityBio’s lead candidate, DB-1303, which is a topoisomerase-1 inhibitor-based ADC directed against Human Epidermal Growth Factor Receptor 2 (HER2), a target that is overexpressed in a variety of cancers, which contributes to the aggressive growth and spread of cancer cells. Antibody therapy targeting HER2 has been shown to be an effective treatment strategy for HER2-expressing cancers. The DB-1303 program received the Fast Track designation from the U.S. Food and Drug Administration (“FDA”) and is currently in a Phase 2 clinical trial (NCT05150691) for HER2-expressing advanced solid tumors.
BioNTech will also gain access to a second topoisomerase-1 inhibitor-based ADC candidate, DB-1311.
“Over the last years, the ADC field has made significant progress, overcoming several limitations and demonstrating its potential as a broadly applicable precision medicine drug class that might be an alternative to standard chemotherapy,” said Prof. Ugur Sahin, M.D., Chief Executive Officer and Co-Founder of BioNTech. “The addition of these two ADCs to our portfolio strengthens our pipeline of immunotherapies and expands our capabilities with the aim to provide therapeutic benefits for patients with a range of solid tumors, along the entire patient journey.”
“We are delighted to partner with BioNTech, a leading company which brings transformational medicine to patients through innovation,” said John Zhu, Ph.D., Founder and CEO of DualityBio. “This is a recognition of not only DualityBio’s next-generation ADC platform, but also its internal discovery and development capabilities. With this strategic partnership, we are committed to working together to advance the development of innovative therapies for the benefit of patients worldwide.”
Under the terms of the agreements, DualityBio will receive upfront payments for both asset licenses totaling
About DB-1303
DB-1303, a third generation HER2 ADC molecule built from DualityBio’s proprietary Duality Immune Toxin Antibody Conjugates (DITAC) platform, exhibited potent antitumor activity in both HER2 positive and HER2 low tumor models with a favorable safety profile and a potentially expanded therapeutic window. Both preclinical data and preliminary clinical data from DB-1303 suggest the potential of DB-1303 to address unmet medical needs in various HER2 expressing cancers.
About DB-1311
DB-1311 is an ADC comprised of a humanized antibody and DualityBio’s proprietary DITAC linker-payload. It has exhibited potent antitumor activity in a range of tumor models representing multiple cancer types and has been well tolerated in preclinical studies, with a good pharmacokinetics profile. The wide therapeutic window demonstrated by preclinical antitumor activity and its safety profile support the potential of DB-1311 to address unmet medical needs across a broad range of cancers.
