What was measured

Disease Control Rate (DCR) was defined as the percentage of participants who achieved a best overall response of CR, PR, or stable disease (SD) during study treatment. Confirmation of CR/PR was required. DCR based on independent central review and investigator assessment is reported.

Analysis population: Disease control rate 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.
