Regulatory approval

Published by the Food and Drug Administration.

The U.S. Food and Drug Administration granted approval to trastuzumab emtansine as a monotherapy for the treatment of patients with HER2-positive, metastatic breast cancer who previously received trastuzumab and a taxane, separately or in combination. Patients should have either received prior therapy for metastatic disease or developed disease recurrence during or within six months of completing adjuvant therapy. The FDA product label states to select patients for therapy based on an FDA-approved companion diagnostic for Kadcyla.
