A confirmed CR was defined in above outcome measures. The PD was defined at least 20% increase in sum of diameters of target lesions (compared with nadir at 2 consecutive visits with an absolute increase of 5 mm), unequivocal progression of existing non-target lesions or new lesion. For participants who were alive and no documented PD at the time of data cutoff for analysis, DoR was censored at the last evaluable disease assessment date. Median DoR was calculated using Kaplan-Meier method.","groups":[{"description":"Drug: Durvalumab IV infusion every 3 weeks with gemcitabine plus cisplatin up to 8 cycles followed by monotherapy every 4 weeks until disease progression or other discontinuation criteria.","id":"OG000","title":"Durvalumab + Gemcitabine + Cisplatin"},{"description":"Drug: Placebo IV infusion every 3 weeks with gemcitabine plus cisplatin up to 8 cycles followed by monotherapy every 4 weeks until disease progression or other discontinuation criteria.","id":"OG001","title":"Placebo + Gemcitabine + Cisplatin"}],"paramType":"NUMBER","populationDescription":"Full analysis set - subjects with objective response and measurable disease at baseline","reportingStatus":"POSTED","timeFrame":"Tumor assessments (per RECIST 1.1) every 6 weeks for first 24 weeks relative to the date of randomization and then every 8 weeks thereafter.
