Overall Survival
Overall survival was calculated as time from randomization to death. Confidence Intervals estimated using the Brookmeyer Crowley method.
Time frame: Up to 2 years
Kaplan-Meier Estimates of Overall Survival at 12 and 18 Months
Overall survival was defined as the time between date of randomization and death due to any cause. Kaplan-Meier estimates of the percentage of participants who died at each time point was calculated. Confidence Intervals estimated using the Brookmeyer Crowley method.
Time frame: Month 12 and 18
Number of Participants With Complete Response (CR), Partial Response (PR), Stable Disease (SD), Progressive Disease (PD) or Not Evaluable
CR, PR, SD and PD will be evaluated as per RECIST version 1.1 criteria. Complete Response (CR) was defined as disappearance of all target and non target lesions and any pathological lymph nodes must be \<10 millimeter (mm) in the short axis. Partial Response (PR) was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters (e.g. percent change from baseline). Stable Disease (SD) was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease. Progressive Disease was defined as at least a 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g. percent change from nadir, where nadir is defined as the smallest sum of diameters recorded since treatment start). In addition, the sum must have an absolute increase from nadir of 5mm.
Time frame: Up to 2 years
Kaplan-Meier Estimates of Progression-Free Survival (PFS)
PFS is defined as time from the date of randomization to the date of disease progression as per RECIST v1.1. or death whichever occurs earlier. Progressive Disease was defined as at least a 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g. percent change from nadir, where nadir is defined as the smallest sum of diameters recorded since treatment start). In addition, the sum must have an absolute increase from nadir of 5mm. Confidence Intervals estimated using the Brookmeyer Crowley method.

Objective Response Rate
ORR was calculated as the percentage of participants with a confirmed complete response (CR) or partial response (PR) relative to the total number of participants in the analysis population per response evaluation criteria in solid tumors (RECIST) version (v)1.1. Complete Response (CR) was defined as disappearance of all target and non target lesions and any pathological lymph nodes must be \<10 millimeter (mm) in the short axis. Partial Response (PR) was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters.
Time frame: Up to 2 years
Kaplan-Meier Estimates of Duration of Response (DOR) in Participants With Objective Response
DOR is defined as the time for first documented evidence of CR or PR until disease progression or death, per RECIST 1.1 criteria. Complete Response (CR) was defined as disappearance of all target and non target lesions and any pathological lymph nodes must be \<10 millimeter (mm) in the short axis. Partial Response (PR) was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters. Confidence Intervals estimated using the Brookmeyer Crowley method.
Time frame: Up to 2 years
Disease Control Rate (DCR)
DCR is defined as the percentage of participants with a confirmed CR + PR at any time, plus SD =\>12 weeks as per RECIST v1.1. Complete Response (CR) was defined as disappearance of all target and non target lesions and any pathological lymph nodes must be \<10 millimeter (mm) in the short axis. Partial Response (PR) was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters (e.g. percent change from baseline). Stable Disease (SD) was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease.
Time frame: Up to 2 years
Number of Participants With iRECIST Complete Response (iCR), Partial Response (iPR), Unconfirmed Progressive Disease (iUPD), Confirmed Progressive Disease (iCPD), Stable Disease (iSD) or Not Evaluable
Modified RECIST 1.1 for immune-based therapeutics (iRECIST) is based on RECIST v 1.1 but adapted to account for the unique tumor response seen with immunotherapeutic drugs. iRECIST was used to assess tumor response and progression and make treatment decisions. iCR: disappearance of all target lesions; iPR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters (e.g. percent change from baseline). iCPD: either 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions; iSD: stable disease in the absence of CR or PD and iUPD: unconfirmed progressive disease when PD is unconfirmed and NE: not evaluable.
Time frame: Up to 2 years
Kaplan-Meier Estimates of iRECIST Progression-free Survival (iPFS)
iPFS is defined as time from the date of randomization to the date of disease progression or death, whichever occurs earlier, per iRECIST criteria. Progressive Disease was defined as at least a 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g. percent change from nadir, where nadir is defined as the smallest sum of diameters recorded since treatment start). In addition, the sum must have an absolute increase from nadir of 5mm. Confidence Intervals estimated using the Brookmeyer Crowley method.
Time frame: Up to 2 years
iRECIST Objective Response Rate (iORR)
iORR is defined as the percentage of participants with a confirmed iCR or iPR at any time per iRECIST criteria. iCR was defined as disappearance of all target and non target lesions and any pathological lymph nodes must be \<10 millimeter (mm) in the short axis. iPR was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters.
