Regulatory approval

Published by the Food and Drug Administration.

The U.S. Food and Drug Administration granted accelerated approval to trastuzumab deruxtecan for the treatment of adult patients with unresectable or metastatic non-small cell lung cancer (NSCLC) whose tumors have activating HER2 (ERBB2) mutations, as detected by an FDA-approved test, and who have received a prior systemic therapy. The product label states that these indications are approved under accelerated approval based on objective response rate and duration of response and that continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
