Note: the dose is different from the FDA-approved dose for breast cancer.
Patients had received a median of two prior therapies for advanced or metastatic disease (17% had received at least four prior therapies, 72% had previously received ramucirumab and 86% had received taxanes).
The median time since the last administration of trastuzumab was 5.9 months in the trastuzumab deruxtecan group and 6.5 months among those in the investigator's choice group.
Biomarker eligibility criteria
- HER2 over-expression
Chemotherapy
- Fam-trastuzumab deruxtecan (Enhertu) 6.4 mg/kg IV once on day 1
