Biotheus Expanded Their Partnership with Hansoh Pharma for Developing EGFR/cMET Bispecific Antibody-Drug Conjugates

"Biotheus and Hansoh Pharma Collaboration

Biotheus Inc. (Biotheus), a clinical-stage biotech company focusing on the discovery and development of biologics for oncology and inflammatory diseases, and Hansoh Pharmaceutical Group Co., Ltd. (Hansoh Pharma,03692.HK), China’s leading innovation-driven pharmaceutical company, jointly announced that the two parties will further expand their strategic collaboration, following their current partnership since 2022. Biotheus will grant Hansoh Pharma a license to use the proprietary anti-EGFR/cMet bispecific antibody PM1080/HS-20117 independently developed by Biotheus for the development of antibody-drug conjugates products (ADC Product).

Under the terms of the agreement, Hansoh Pharma will obtain exclusive worldwide rights from Biotheus to use PM1080/HS-20117 for the development, production, and commercialization of ADC Product, with the right of sublicense. Biotheus will be eligible to receive up to 5 billion RMB in upfront and success-based milestones for ADC Product, as well as tiered royalties based on global net sales from Hansoh Pharma.

PM1080/HS-20117 is a 1+1 heterodimeric structure of EGFR/cMet bispecific antibody, which can inhibit the growth and survival of tumors by specifically targeting the tumor antigens EGFR and cMet, and is currently in phase I clinical trials.

“This is the second collaboration between Hansoh and Biotheus. We really appreciate Hansoh’s confidence in the potential of PM1080”, said Mr. Xiaolin Liu, Co-founder, Chairman and Chief Executive Officer of Biotheus. “Bispecific ADCs have a potential advantage for better tumor enrichment, overall efficacy and safety. Hansoh develops an outstanding ADC platform, and this collaboration will facilitate the synergy between Hansoh’s ADC expertise and Biotheus’ antibody capabilities. Through this collaboration, we hope to develop a novel EGFR/cMet bispecific ADC with better efficacy and safety for cancer patients worldwide.”

 “We are delighted to expand our partnership with Biotheus.” Said Ms Eliza Sun, Executive Director of the Board at Hansoh. “This collaboration combines Hansoh’s proprietary ADC Platform technology with Biotheus’ novel bispecific antibody. We hope this new approach will further increase the clinical benefit in patients with NSCLC or other solid tumors. We are confident in our ability to offer transformative treatment options to cancer patients in China and worldwide. This is made possible through our extensive experience in clinical development, exceptional commercialization efforts, and external partnerships.”
