What was measured

Duration of response (DoR) is defined as the time from the initial response (complete response \[CR\] or partial response \[PR\]) until documented tumor progression or death from any cause. DoR is only defined for participants who achieved confirmed CR or PR. CR was defined as a 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: Full Analysis Set includes all subjects for whom study treatment was assigned by randomization. From the Full Analysis Set, 47 participants had a confirmed CR or PR in T-DXd 5.4 mg/kg arm, and 28 participants in T-DXd 6.4 mg/kg arm

Groups in this outcome
