Condition/Disease
The efficacy of T-DXd with pembrolizumab versus platinum-based chemotherapy with pembrolizumab was compared using PFS as assessed by BICR. PFS was defined as the time interval elapsed from the date of randomization to the date of radiographic disease progression or death from any cause. Tumor response was assessed by BICR tumor scans and determined using the Solid Tumor Response Assessment Criteria, version 1.1 (RECIST v1.1).
