AstraZeneca and Daiichi Sankyo’s breast cancer therapeutic Enhertu received supplemental approval from the U.S. Food and Drug Administration. Enhertu was approved for treating adult patients with unresectable or metastatic HER2-positive breast cancer who have received a prior anti-HER2-based regimen either in the metastatic setting or in the neoadjuvant or adjuvant setting and have developed disease recurrence during or within six months of completing therapy.

AstraZeneca’s candidate breast cancer therapy Enhertu received a fourth Breakthrough Therapy Designation from the U.S. Food and Drug Administration after the health regulator issued another BTD based on a Phase III trial presented at the European Society for Medical Oncology Congress 2021.

The U.S. Food and Drug Administration approved Seattle Genetics’ Tukysa (tucatinib) in combination with chemotherapy agents trastuzumab and capecitabine for adults with HER2+ breast cancer that cannot be surgically removed or has metastasized to other parts of the body.

The U.S. Food and Drug Administration granted approval to Seattle Genetics Inc.’s Tukysa tablets in combination with trastuzumab and capecitabine for adult patients with advanced unresectable or metastatic HER2-positive breast cancer, including patients with brain metastases, who have received one or more prior anti-HER2-based regimens in the metastatic setting.
