NMPA (China) approves Enhertu to treat adult patients with unresectable or metastatic HER2-positive breast cancer who have received one or more prior anti-HER2-based regimens. AstraZeneca + Daiichi Sankyo.
AstraZeneca and Daiichi Sankyo’s Enhertu (trastuzumab deruxtecan) has been approved in China as a monotherapy for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received one or more prior anti-HER2-based regimens. Enhertu is a specifically engineered HER2-directed antibody drug conjugate (ADC) being jointly developed and commercialised by AstraZeneca and Daiichi Sankyo.
The approval by China’s National Medical Products Administration (NMPA) is based on the results of the DESTINY-Breast03 Phase III trial, where Enhertu demonstrated a 72% reduction in the risk of disease progression or death compared to trastuzumab emtansine (T-DM1) (hazard ratio [HR] 0.28; 95% confidence interval [CI] 0.22-0.37; p<0.000001) in patients with her2-positive unresectable and or metastatic breast cancer previously treated with trastuzumab and a taxane.></0.000001)>
