Primary Outcome Measures :
  1. Part A: Number of Participants With Confirmed Best Overall Response (BOR) as Per Response Evaluation Criteria in Solid Tumors Version (RECIST) 1.1 [ Time Frame: Up to 113 weeks ]
    Confirmed BOR was determined according to RECIST 1.1and as adjudicated by an Independent Endpoint Review Committee(IERC) and defined as best response of any of complete response (CR), partial response(PR), stable disease(SD) and progressive disease(PD) recorded from date of randomization until disease progression/recurrence(taking smallest measurement recorded since start of treatment as reference). CR:Disappearance of all evidence of target/non-target lesions. PR:At least 30%reduction from baseline in sum of longest diameter(SLD) of all lesions. SD:Neither sufficient increase to qualify for PD nor sufficient shrinkage to qualify for PR. PD:at least a20% increase in SLD, taking as reference smallest SLD recorded from baseline/appearance of 1or more new lesions and unequivocal progression of non-target lesions. CR or PR must be confirmed by a subsequent tumor assessment preferably at next scheduled 6-weekly assessment, but no sooner than 5 weeks after initial documentation of CR or PR.

  2. Part B: Durable Response Rate (DRR) [ Time Frame: Up to 161 weeks ]
    Durable response is defined as an objective response (confirmed complete response [CR] or confirmed Partial response [PR]) according to Response Evaluation Criteria in Solid Tumors version (RECIST) 1.1, determined by the Independent Endpoint Review Committee (IERC), with a duration of at least 6 months. The DRR was determined as the percentage of participants with an objective response in terms of CR or PR according to RECIST 1.1, as determined by the IERC, with a duration of at least 6 months. CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the sum of the longest diameter (SLD) of all lesions.


Secondary Outcome Measures :
  1. Part A: Duration of Response According to Response Evaluation Criteria in Solid Tumors Version (RECIST) 1.1 [ Time Frame: Up to 325 weeks ]
    The duration of response as determined from IERC tumor assessment was calculated for each participant with a confirmed response (CR or PR) as the time from first observation of response until first observation of documented disease progression or death when death occurs within 12 weeks of the last tumor assessment, whichever occurs first. CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the sum of the longest diameter (SLD) of all lesions. Results were calculated based on Kaplan-Meier estimates.

  2. Part A: Progression-Free Survival (PFS) Time According to Response Evaluation Criteria in Solid Tumors Version (RECIST) 1.1 [ Time Frame: Up to 325 weeks ]
    The PFS time (based on IERC tumor assessments), according to the RECIST 1.1, was defined as the time from first administration of study treatment until first observation of PD or death when death occurred within 12 weeks of the last tumor assessment or first administration of study treatment (whichever was later). PFS time (in months) was defined as: (date of PD or death - date of the first dose of study treatment + 1)/30.4375 (months). PD was defined as at least a 20% increase in the SLD, taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions and unequivocal progression of non-target lesions.

  3. Part A: Number of Participants With Treatment-Related (TR) Treatment-Emergent Adverse Events (TEAEs), Treatment-Related Serious TEAEs and Treatment-Related TEAEs Leading to Death [ Time Frame: Up to 325 weeks ]
    Related Adverse events (AE) were defined according to National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (NCI-CTCAE) as adverse events with relationship to study treatment reported by the investigator. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. Treatment-emergent are events between first dose of study drug that were absent before treatment or that worsened relative to pre-treatment state up to 30 days after last administration. TEAEs included both Serious TEAEs and non-serious TEAEs. Related TEAEs are defined as events with a relationship of missing, unknown, or yes.
