The FDA clearance aids AstraZeneca and Daiichi Sankyo’s plan to position ADCs like Enhertu ahead of chemotherapy in a variety of tumors.

FDA approves Enhertu for metastatic breast cancer with HER2-low or HER2-ultralow expression after showing significant efficacy in the DESTINY-Breast06 trial.

AstraZeneca (AZ) and Daiichi Sankyo’s Enhertu (trastuzumab deruxtecan) has been approved by the US Food and Drug Administration (FDA) to treat a new subset of breast cancer patients.

AstraZeneca AZN and partner Daiichi Sankyo announced that the FDA has approved the supplemental biologics license application (sBLA) seeking approval for expanded use of Enhertu (trastuzumab deruxtecan) for HER2-low metastatic breast cancer in the United States.
