What was measured

ORR was determined in all participants and was defined as the percentage of participants who had a confirmed Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by Blinded Independent Central Review (BICR). Participants with missing data were considered non-responders. Per protocol, only data generated during the initial course of treatment contributed to the analysis.

Analysis population: All participants who received at least one dose of study treatment during the initial course of treatment

Groups in this outcome

Pembrolizumab 200 mg

Participants received pembrolizumab 200 mg by IV infusion on Day 1 of each 21-day cycle (Q3W) for up to 2 years. Eligible participants who stopped the initial course of pembrolizumab due to complete response (CR) or completed initial course of pembrolizumab and had stable disease but progressed after discontinuation, initiated a second course of pembrolizumab at the investigator's discretion for up to an additional year.
