What was measured

Overall survival (OS) was defined as the time from the date of first dose of study drug to the date of death due to any cause.

Analysis population: Overall survival (OS) was assessed in the Full Analysis Set at data cut-off date of 03 May 2021.

Groups in this outcome

Cohort 1: HER2 Overexpressing

Participants with HER2-overexpressing(immunohistochemistry \[IHC\] 3+ or IHC 2+), unresectable and/or metastatic NSCLC adenocarcinoma who received 6.4 mg/kg trastuzumab deruxtecan (DS-8201a). Trastuzumab deruxtecan: Antibody component covalently conjugated to a drug component, prepared by dilution based on body weight for intravenous (IV) infusion.

Cohort 1a: HER2 Overexpressing

Participants with HER2-overexpressing (immunohistochemistry \[IHC\] 3+ or IHC 2+), unresectable and/or metastatic NSCLC adenocarcinoma who received 5.4 mg/kg trastuzumab deruxtecan (DS-8201a). Trastuzumab deruxtecan: Antibody component covalently conjugated to a drug component, prepared by dilution based on body weight for intravenous (IV) infusion.

Cohort 2: HER2 Mutated

Participants with HER2-mutated, unresectable and/or metastatic NSCLC who received 6.4 mg/kg trastuzumab deruxtecan (DS-8201a). Trastuzumab deruxtecan: Antibody component covalently conjugated to a drug component, prepared by dilution based on body weight for intravenous (IV) infusion.
