Milestone launch for Daiichi Sankyo’s Datroway in Japan
Japanese drugmaker Daiichi Sankyo’s (TYO:4568) Datroway (datopotamab deruxtecan) has been launched in the company’s home country for the treatment of adults with hormone receptor (HR) positive, HER2 negative, unresectable or recurrent breast cancer after prior chemotherapy.
Datroway is the first ever TROP2-directed medicine to be launched in Japan for HR positive, HER2 negative breast cancer and is the second DXd antibody drug conjugate (ADC) available based on Daiichi Sankyo’s DXd ADC technology.
Marketing approval was granted by the Japan Ministry of Health, Labor and Welfare in December 2024, based on the results from the TROPION-Breast01 Phase III trial, in which Datroway significantly reduced the risk of disease progression or death by 37% compared to investigator’s choice of chemotherapy.
