Per RECIST 1.1, PD was defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered PD.","dispersionType":"Full Range","groups":[{"description":"Participants received pembrolizumab 200 mg IV on Day 1 of each 21-day cycle PLUS one of three background chemotherapy regimens at investigator's discretion: 1) nab-paclitaxel IV on Days 1, 8 and 15 of each 28-day cycle, 2) paclitaxel IV on Days 1, 8 and 15 of each 28-day cycle, OR 3) gemcitabine/carboplatin (gemcitabine) and an AUC 2 (carboplatin) on Days 1 and 8 of each 21-day cycle.
