Sony and Astellas Enter into Collaborative Research Agreement to Discover a Novel ADC Platform for the Oncology Field
TOKYO, May 16, 2023 /PRNewswire/ -- Sony Corporation (President and CEO: Kimio Maki, "Sony") and Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") today announced that they have entered into a collaborative research agreement to discover a novel Antibody-Drug Conjugate (ADC)*1 platform in oncology based on Sony's unique polymeric material, "KIRAVIA™*2 Backbone*3." ADC is expected to selectively deliver anti-cancer drugs to target cells, thereby increasing efficacy and reducing side effects caused by anti-cancer drugs attacking normal cells. The technology to create linkers which conjugates antibodies and drugs, is considered to be a key to development of a better-performing ADC. This collaborative research leverages the flexibility in design and resulting properties such as high capacity and solubility of KIRAVIA Backbone as a linker of ADC, to effectively deliver anti-cancer drugs to targeted cells in a stable manner, aiming to further enhance therapeutic efficacy by achieving high Drug-to-Antibody Ratio (DAR) etc.
- " ADC is expected to selectively deliver anti-cancer drugs to target cells, thereby increasing efficacy and reducing side effects caused by anti-cancer drugs attacking normal cells.
- The technology to create linkers which conjugates antibodies and drugs, is considered to be a key to development of a better-performing ADC.
- The two companies jointly began exploratory research of new linker technology aimed at creating a new ADC platform in July 2022, and the expected profile was obtained in feasibility studies using human cancer cells.
- Under this agreement, Sony and Astellas will jointly develop and optimize a new ADC platform using the KIRAVIA Backbone as a linker.
