What was measured

Responses assessed using CT scans or magnetic resonance imaging according to standard RECIST 1.1 criteria in order to assess disease progression. CR: Disappearance all target lesions; any pathological lymph nodes reduction in short axis to \< 10 mm (\< 1 cm). PR: \> 30% decrease in sum diameters of target lesions. PD: \> 20% increase in sum diameters lesions. (Note: appearance of one or \> new lesions considered progressions). SD: Neither shrinkage qualify for PR nor increase for PD.

Analysis population: Of the 100 participants enrolled into Part B of the study, 88 participants were evaluable for response per RECIST 1.1. The remaining 12 participants were not evaluable for treatment response.

Groups in this outcome

Part B Arm I (Nivolumab)

Participants enrolled into Arm I received single agent Nivolumab.

Part B Arm II (Nivolumab, Ipilimumab

Participants enrolled into Arm II received combination Nivolumab plus Ipilimumab.
