  • Number of Participants Who Experienced an Adverse Event (AE) [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to be a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE. The number of participants who experienced at least one AE was reported.
  • Number of Participants Who Discontinued Study Drug Due to an AE [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to be a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE. The number of participants who discontinued study treatment due to an AE was reported.

Current Secondary Outcome Measures  ICMJE
 (submitted: September 10, 2019)
  • Objective Response Rate (ORR) Per RECIST 1.1 as Assessed by Central Radiologists' Review [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    ORR was defined as the percentage of participants who had a Complete Response (CR: disappearance of all lesions) or a Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions, without evidence of progression based on non-target or new lesions) as assessed by central radiologists' review per RECIST 1.1 which is modified for this study to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The percentage of participants who experienced a confirmed CR or PR per RECIST 1.1 as assessed by central radiologists' review was reported for each arm.
  • ORR Per Immune-related RECIST (irRECIST) as Assessed by Central Radiologists' Review [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    ORR was defined as the percentage of participants who had confirmed responses assessed using RECIST 1.1 before PD or an immune-related Complete Response (irCR: Disappearance of all target lesions and non-target) or an immune-related Partial Response (irPR: At least a 30% decrease in the sum of diameters of target lesions, stability of non-target lesions no new lesions) after a single PD per irRECIST as assessed by central radiologists' review. Per RECIST 1.1, CR or PR was confirmed by repeated radiographic assessment no less than 4 weeks from the first documented response. If site-assessed PD was verified by the central imaging vendor, the site could elect to continue treatment, repeat imaging ≥4 weeks later and assess tumor response or confirmed progression per irRECIST. The percentage of participants who experienced a CR or PR per RECIST 1.1 or irCR or irPR per irRECIST as assessed by central radiologists' review was reported for each arm.
  • Duration of Response (DOR) Per RECIST 1.1 as Assessed by Central Radiologists' Review [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    For participants who demonstrated a confirmed CR (disappearance of all lesions) or confirmed PR (≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by central radiologists' review, DOR was defined as the time from first documented evidence of a CR or PR until disease progression or death. RECIST 1.1 has been modified for this study to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The DOR per RECIST 1.1 as assessed by central radiologists' review for all participants who experienced a confirmed CR or PR was reported for each arm.
  • DOR Per irRECIST as Assessed by Central Radiologists' Review [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    For participants who demonstrated a confirmed CR (disappearance of all target lesions and non-target lesions) or PR (≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1 or CR or PR after a single PD, DOR was defined as the time from the first documented CR or PR, or irCR or irPR, until an immune-related progressive disease (irPD) or death. DOR for participants who had not progressed or died at the time of analysis was to be censored at the date of their last tumor assessment. Per irRECIST, irPD was defined as after a single PD, ≥20% increase in the sum of diameters of target lesions, or unequivocal worsening of non-target lesions or the appearance of new lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of ≥5 mm. The DOR per irRECIST as assessed by central radiologists' review for all participants who experienced a confirmed CR or PR or irCR or irPR was reported for each arm.
  • Progression-Free Survival (PFS) Per RECIST 1.1 as Assessed by Central Radiologists' Review [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as either a 20% increase from nadir in target lesions, unequivocal progression of nontarget lesions, or the appearance of new lesions. PFS per RECIST 1.1 as assessed by central radiologists' review was reported for each arm.
  • PFS Per irRECIST as Assessed by Central Radiologists' Review [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    PFS was defined as the time from randomization to the first documented immune-based confirmed progressive disease (iCPD) or death due to any cause, whichever occurred first. Per iRECIST, iCPD is defined as worsening of any existing cause of progression, or the appearance of any other cause of progression, relative to the initial appearance of progressive disease by RECIST 1.1. PFS per irRECIST as assessed by central radiologists' review is reported for each arm.
  • Overall Survival (OS) [ Time Frame: Up to ~13 months (through database cut-off date of 19-Sept-2017) ]
    OS was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up. OS was reported for each arm using a 19-Sept-2017 data cut-off date.
