BEIJING, China, and Shanghai, China, January 3, 2023 - Biocytogen Pharmaceuticals (Beijing) Co., Ltd. ("Biocytogen", SEHK : 02315) a clinical-stage biotechnology company with a focus on the antibody discovery and development based on its proprietary RenMice^TM Platforms and Hansoh Pharmaceutical Group Company Limited (“Hansoh Pharma”, SEHK: 3692),  a leading innovation-driven pharmaceutical company with a focus on the treatment of major diseases including oncology, infectious diseases, CNS disorders, metabolic diseases and autoimmune diseases, today announced an antibody collaboration, assignment and exclusive license agreement. Biocytogen will provide a license to Hansoh Pharma for their selected fully human antibody molecules against the designated target for the development, manufacturing and commercialization globally. Under the agreement, Biocytogen will receive an upfront payment and will be eligible to receive development and commercial milestones of up to tens of millions of Chinese yuan, as well as single-digit tiered royalties on net sales.

“We are very excited to partner with Hansoh Pharma, one of the largest pharmaceutical companies in China. The licensed antibodies were selected from Biocytogen’s Project Integrum programs and generated from our proprietary fully human antibody RenMice^TM target-knockout mice. The antibodies possess highest possible diversity to improve the success rate of antibody discovery,” said Dr. Yuelei Shen, President and CEO of Biocytogen. “Thanks to Hansoh Pharma’s recognition of our RenMice^TM platforms and Project Integrum. We believe Hansoh Pharma’s strong R&D, manufacturing and commercialization capabilities will accelerate the development of RenMiceTM-derived antibody molecules and bring the benefits to patients worldwide.”

Project Integrum is a large-scale antibody drug development project for 1000+ potential drug targets using RenMice^TM (RenMab^TM, RenLite^® and RenNano^®) target knockout mice. Different from the traditional mechanism of action (MOA)-based drug development strategy, Project Integrum uses large-scale in vivo drug efficacy screening methods to discover innovative drugs with excellent safety and efficacy. So far, we have completed making RenMice^TM KO for 1000+ targets. In addition, we have developed a large variety of preclinical antibody assets including 10 fully human bispecific antibodies, 20+ bispecific ADCs, 10+ TCR-mimic antibodies, 30+ monoclonal antibodies against novel targets, and 600+ antibody hits. Antibody molecules generated by Project Integrum have high specificity, high affinity and good druggability, which have attracted many top biopharmaceutical companys to obtain a license or reach a drug co-development agreement with us, including Merck KGaA, ADC Therapeutics, Remgen, NJCTTQ, etc.
