Participants underwent radiographic tumor assessments every 6 weeks (+/- 5 days) from week 9 (+/- 5 days) for the first year on treatment, then every 12 weeks after the first year on treatment until documented disease progression. The PFS curves were estimated using KM method. Two-sided 95% CI for median PFS were computed by Brookmeyer and Crowley method (using log-log transformation). Participants who did not progress or die were censored on the date of their last evaluable tumor assessment. Participants who started any subsequent anti-cancer therapy (including on-treatment palliative RT of non-target bone lesions or CNS lesions) without a prior reported progression were to be censored at the last evaluable tumor assessment prior to or on initiation of the subsequent anti-cancer therapy.","dispersionType":"95% Confidence Interval","groups":[{"description":"Nivolumab 3 mg/kg solution intravenously every 2 weeks until documented disease progression, discontinuation due to toxicity, withdrawal of consent or the study ends.
