Time frame
From the first documented evidence of a response (complete or partial) until disease progression or death, up to approximately 19 months.

What was measured

DoR, defined as time from the initial response (CR or PR) by BICR and Investigator assessment until documented tumor progression or death from any cause. DoR was assessed in the Full Analysis Set at data cut-off date of 01 Nov 2022.

Analysis population: DoR 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).

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
