AstraZeneca and Daiichi Sankyo announced that Enhertu®, their engineered HER2-directed antibody drug conjugate (ADC), has been approved in China as a monotherapy to treat patients with unresectable or metastatic HER2-low (IHC 1+ or IHC 2+/ISH-) breast cancer who have received a prior systemic therapy in the metastatic setting or developed disease recurrence during or within six months of completing adjuvant chemotherapy. The approval by China’s National Medical Products Administration is based on the results of the DESTINY-Breast04 Phase III trial.
