Outcomes
Primary Outcomes
Complete Response (CR) Rate at the End of Study Intervention as Assessed by Blinded Independent Central Review (BICR) Per Lugano 2014 Response Criteria
Time Frame: Up to approximately 24 months
CR rate was assessed by BICR using Computed Tomography (CT) and PET scan according to Lugano 2014 response criteria (Cheson, B.D. et al, Journal of Clinical Oncology, 2014). At each timepoint, CR was determined by combining the anatomic response, metabolic response, and clinical data. The criteria for CR included complete metabolic (no/minimal 2-fluorodeoxyglucose \[FDG\] uptake) and radiologic response (target lesions regress to ≤1.5 cm in longest transverse diameter of a lesion) and no new lesions. Per protocol, participants who discontinued study intervention during pembrolizumab monotherapy, chemotherapy, or pembrolizumab consolidation, or are lost to follow-up, or receive any new non-study anticancer therapy prior to end of treatment were classified as non-responders. The percentage of participants who had CR after the completion of pembrolizumab consolidation is presented.
