Patients will receive one of the following chemotherapies as determined by the physician:
- Progression-free Survival (PFS) as Assessed by Blinded Independent Central Review (BICR) [ Time Frame: From randomization until documented progressive disease (PD) or death, whichever occurred first, for censored participants at the date of last adequate tumor assessment (up to 24 months) ]PFS was defined as the time from randomization to the earliest documented disease progression date or death due to any cause whichever occurred first. Disease progression was defined as at least a 20% increase in the sum of diameters of measured lesions taking as references the smallest sum of diameters recorded on study (including Baseline) and an absolute increase of greater than or equal to (>=) 5 millimeter (mm). Appearance of new lesions >=10 mm in diameter also constituted PD. If a participant did not have an event at the time of the analysis cutoff or at the start of any new therapy, PFS was censored at the date of last adequate tumor assessment.
- Overall Survival (OS) [ Time Frame: From randomization date to the date of death, for censored participants at their last contact date (up to 24 months) ]OS was defined as the time from randomization to death due to any cause. Participants who were alive at the data cutoff date were censored for overall survival at their last contact date.
- Objective Response Rate Per Response Evaluation Criteria in Solid Tumors (RECIST), Version 1.1 (RECIST V1.1) [ Time Frame: From randomization until disease progression or death (up to 24 months) ]ORR was defined as the percentage of participants achieving an overall best response of complete response (CR) or partial response (PR) (responders). CR was defined as disappearance of target and non-target lesions and normalization of tumor markers. Pathological lymph nodes must have short axis measures less than (<) 10 mm, PR was defined as at least a 30% decrease in the sum of measures (longest diameter for tumor lesions and short axis measure for nodes) of target lesions, taking as reference the Baseline sum of diameters. Non-target lesions must be non-progressive disease.
- Duration of Response (DOR) [ Time Frame: From the first radiographic evidence of response to the first documentation of PD or death, for censored participants at their last radiological assessment (up to 24 months) ]DOR was defined as the time from first radiographic evidence of response to the earliest documented progression date or death due to any cause, and was calculated on responders only. Responders with no PD or death date or subsequent anticancer therapy by the data cutoff date, were censored for DOR at their last radiological assessment. Responders who received subsequent anticancer therapy prior to PD or death were censored at their last radiological assessment prior to initiation of subsequent anticancer therapy.
- Disease Control Rate [ Time Frame: Week 24 ]Disease control rate was defined as percentage of participants with disease control. Disease control was defined as a best response of CR or PR, or stable disease (SD) documented at Week 24 or later. CR was defined as disappearance of target and non-target lesions and normalization of tumor markers. Pathological lymph nodes must have short axis measures <10 mm, and PR is defined as at least a 30% decrease in the sum of measures (longest diameter for tumor lesions and short axis measure for nodes) of target lesions, taking as reference the Baseline sum of diameters. Non-target lesions must be non-progressive disease. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD taking as reference the smallest sum of diameters on study.
- Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: From the first dose of study drug until 30 days after the last dose (up to 25 months) ]An AE was any untoward medical occurrence in a participant who received vaccine without regard to possibility of causal relationship. SAE: an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial/prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
- Number of Participants With Shift Greater Than or Equal to Grade 3 From Baseline in Laboratory Parameter Values Based on National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE), Version 4.3 [ Time Frame: From the first dose of study drug until 30 days after the last dose (up to 25 months) ]Number of participants with shifts from normal Baseline values (Grade 0) to abnormal post-baseline values (shift to greater than or equal to Grade 3) were reported as per NCI-CTCAE, V4.3 graded from Grade 1 to 5. Grade 1: Mild; asymptomatic/ mild symptoms; clinical/diagnostic observations only; intervention not indicated. Grade 2: Moderate; minimal, local/noninvasive intervention indicated. Grade 3: Severe/medically significant but not immediately life-threatening; hospitalization/prolongation of hospitalization indicated. Grade 4: Life-threatening consequences; urgent intervention indicated. Grade 5: Death. Shifts in lab parameter from Grade 0 to 3, Grade 0 to 4 and Grade 0 to Low 3 and 4 and Grade 0 to High 3 and 4 (for parameters total hemoglobin, lymphocytes, white blood cells, calcium, magnesium, potassium, and sodium) were reported.
