What was measured

Confirmed objective response rate (ORR), defined as the number (percentage) of participants with complete response (CR) or partial response (PR), were assessed by blinded independent central review (BICR) based on Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. CR was defined as the disappearance of all target lesions and PR was defined as at least a 30% decrease in the sum of diameters of target lesions.

Analysis population: ORR was assessed in the Full Analysis Set, which included 1 participant who was randomized/registered to T-DXd 6.4 mg/kg Q3W but actually received T-DXd 5.4 mg/kg Q3W.

Groups in this outcome

T-DXd 5.4 mg/kg Q3W

Participants were randomized to receive intravenous T-DXd administered at a dose of 5.4 mg/kg every 3 weeks (Q3W).

T-DXd 6.4 mg/kg Q3W

Participants were randomized to receive intravenous T-DXd administered at a dose of 6.4 mg/kg every 3 weeks (Q3W).
