What was measured

For participants who demonstrated a confirmed Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, Duration of Response (DOR) was defined as the time from first documented evidence of a CR or PR until progressive disease (PD) or death. DOR for participants who had not progressed or died at the time of analysis was to be censored at the date of their last tumor assessment. Per RECIST 1.1, PD was defined as at least a 20% increase in the sum of diameters of target lesions as well as an absolute increase of at least a 5 mm in the sum of diameters. The appearance of one or more new lesions was also considered PD. DOR assessments were based on BICR.

Analysis population: All randomized participants, regardless of whether or not they received study treatment, who demonstrated a confirmed response (CR or PR). Participants were included in the treatment arm to which they were randomized.

Groups in this outcome

Pembrolizumab

Participants received pembrolizumab 200 mg IV every Q3W for up to 35 administrations (up to \~2 years).

Chemotherapy

Participants received capecitabine, eribulin, gemcitabine, or vinorelbine as single agent chemotherapy chosen by the treating physician (Treatment of Physician's Choice, TPC) in accordance with local regulations and guidelines.
