Enhertu (trastuzumab deruxtecan) has been approved by the US Food and Drug Administration to treat non-small cell lung cancer whose tumours have activating HER2 mutations. The accelerated approval comes just a week after Enhertu, an antibody-drug conjugate (ADC), was authorised by the FDA for a new breast cancer indication. The decision, announced on 12 August, brings the total number of US regulatory approvals for the drug up to five, all of which are for cancers expressing the HER2 protein.
