Biocytogen Enters into Antibody Agreement with ADC Therapeutics

Biocytogen Pharmaceuticals (Beijing) Co., Ltd. ("Biocytogen", HKEX: 02315) today announced that it has entered into an evaluation and option agreement with ADC Therapeutics SA. Biocytogen will grant ADC Therapeutics a license to evaluate Biocytogen’s proprietary antibodies against three tumor targets, with an option to license selected antibodies at a later date for global ADC development and commercialization. Biocytogen reserves all global rights for these antibodies beyond ADC development. Biocytogen will receive an upfront payment. For each option exercised, Biocytogen will be entitled to an option-exercise fee, and development and commercial milestone payments, which potentially total tens of millions of US dollars, as well as single-digit royalties on net sales.

Under the agreement, Biocytogen will provide ADC Therapeutics with monoclonal and/or biparatopic antibodies directed against three tumor targets, generated through Biocytogen’s Project Integrum (also called RenMice^TM HiTS Platform). ADC Therapeutics will carry out feasibility studies and be responsible for further development and commercialization of the ADC products if the company exercises an option.

“ADC Therapeutics is a leader in the development and commercialization of ADCs. We believe this collaboration with ADC Therapeutics will underscore the value of Biocytogen’s proprietary antibody discovery and screening platforms,” said Dr. Yuelei Shen, President and CEO of Biocytogen. “We’ve been dedicated to expanding the possibilities of antibody-based therapeutics in disease treatment, through the exploration of new types of targets and modalities through Project Integrum. The combination of Biocytogen’s strength in antibody development with ADC Therapeutics’ expertise and track record in payload and linker technology may lead to the generation of novel ADC medicines for unmet medical needs in the future.”

“We are pleased to enter this collaboration with Biocytogen as we continue expanding our toolbox to realize the full potential of our ADC platform,” said Patrick van Berkel, PhD, Chief Scientific Officer of ADC Therapeutics. “We look forward to evaluating the fully human antibodies from Biocytogen’s proprietary discovery platform, which have the potential to accelerate the development of our novel ADCs.”
