- Progression-Free Survival (PFS) [ Time Frame: Radiographic evaluation every 9 weeks, clinical evaluation every cycle (data cutoff date: 04 March 2016); maximum duration of follow up for PFS was 34 months. ]PFS is defined as the number of months from the date the participant was randomized to the date of radiographic progression as determined by the central imaging center, or to the date of all cause deaths within 63 days of last tumor assessment if disease progression was not reached.
- Overall Survival (OS) [ Time Frame: From Cycle 1 Day 1 until participant's death or 3 years post discontinuation (data cutoff date: 04 March 2016); maximum duration of follow up for OS was 72 months. ]Time to death for a given participant was defined as the number of months from the day the participant is randomized to the date of the participant's death. All events of death were included, regardless of whether the event occurs while the participant was still taking study drug, or after the participant discontinued study drug. If a participant had not died, then the data will be censored at the date when the participant was last known to be alive.
- Clinical Benefit Rate (CBR) at Week 18 [ Time Frame: Week 18 ]
CBR: percentage of participants who were progression-free at 18 weeks, defined as complete response (CR), partial response (PR), stable disease (SD) or non-CR/non-disease progression (PD) per Response Evaluation Criteria in Solid Tumors [RECIST] 1.1.
CR: The disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 0 mm. PR: >= 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters (SOD). PD: >= 20% increase in the SOD of target lesions, taking as reference the smallest SOD recorded since the treatment started (baseline or after) or the appearance of >=1 new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest SOD since the treatment started (baseline or after).
- Objective Response Rate (ORR) [ Time Frame: Radiographic evaluation every 9 weeks, clinical evaluation every cycle (data cutoff date: 04 March 2016); maximum duration of follow up for ORR was 34 months. ]The objective response rate, defined as percentage of participants with a confirmed CR or PR based on RECIST 1.1 criteria. CR: The disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 0 mm. PR: >= 30% decrease in the sum of diameters of target lesions, taking as reference the baseline SODs.
- Change From Baseline at Week 18 in European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Chemotherapy-Induced Peripheral Neuropathy Module (EORTC QLQ-CIPN20) Sensory Subscale Score [ Time Frame: Baseline, Week 18 ]EORTC QLQ-CIPN20 sensory subscale score was calculated following the standard scoring algorithm, transformed to a 0 (low quality of life) to 100 (best quality of life) scale. A positive change from baseline indicates improvement.
