- Percentage of Participants With a Confirmed Objective Response of Complete Response (CR) or Partial Response (PR) as Assessed by the Independent Review Facility (IRF) According to RECIST v1.1 [ Time Frame: Baseline until confirmed disease progression or death, whichever occurred first (assessed at every 9 weeks for the first 12 months, thereafter every 12 weeks until data cutoff date 04 July 2016, up to maximum length of follow-up of 23.52 months) ]Tumor response was assessed by the IRF according to RECIST v1.1. CR was defined as disappearance of all target and non-target lesions and (if applicable) normalization of tumor marker levels. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (<) 10 millimeters (mm). PR was defined as greater than or equal to (≥) 30 percent (%) decrease in sum of longest diameter (LD) of target lesions in reference to Baseline sum LD. Response was to be confirmed ≥4 weeks after the initial assessment of CR or PR. The percentage of participants with a confirmed objective response of CR or PR was reported. The exact 95% confidence interval (CI) was calculated using the Clopper-Pearson method.
- Duration of Response (DOR) as Assessed by the IRF According to RECIST v1.1 [ Time Frame: Baseline until confirmed disease progression or death, whichever occurred first (assessed at every 9 weeks for the first 12 months, thereafter every 12 weeks until data cutoff date 04 July 2016, up to maximum length of follow-up of 23.52 months) ]DOR was defined as the time from the initial occurrence of documented CR or PR (whichever occurred first) until documented disease progression or death due to any cause on study, whichever occurred first. Tumor response was assessed by the IRF according to RECIST v1.1. CR was defined as disappearance of all target and non-target lesions and (if applicable) normalization of tumor marker levels. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR was defined as ≥30% decrease in sum of LD of target lesions in reference to Baseline sum LD. Response was to be confirmed ≥4 weeks after the initial assessment of CR or PR.
- DOR as Assessed by the Investigator According to RECIST v1.1 [ Time Frame: Baseline until confirmed disease progression or death, whichever occurred first (assessed at every 9 weeks for the first 12 months, thereafter every 12 weeks until data cutoff date 04 July 2016, up to maximum length of follow-up of 23.52 months) ]DOR was defined as the time from the initial occurrence of documented CR or PR (whichever occurred first) until documented disease progression or death due to any cause on study, whichever occurred first. Tumor response was assessed by the investigator according to RECIST v1.1. CR was defined as disappearance of all target and non-target lesions and no new measurable or unmeasurable lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR was defined as ≥30% decrease in sum of LD of target lesions in reference to Baseline sum LD.
- Percentage of Participants With Death or Disease Progression as Assessed by the IRF According to RECIST v1.1 [ Time Frame: Baseline until confirmed disease progression or death, whichever occurred first (assessed at every 9 weeks for the first 12 months, thereafter every 12 weeks until data cutoff date 04 July 2016, up to maximum length of follow-up of 23.52 months) ]Tumor response was assessed by the IRF according to RECIST v1.1. Disease progression or PD was defined as ≥20% increase in sum LD in reference to the smallest on-study sum LD, or the appearance of new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.
- Progression-Free Survival (PFS) as Assessed by the IRF According to RECIST v1.1 [ Time Frame: Baseline until confirmed disease progression or death, whichever occurred first (assessed at every 9 weeks for the first 12 months, thereafter every 12 weeks until data cutoff date 04 July 2016, up to maximum length of follow-up of 23.52 months) ]PFS was defined as the time from start of treatment to the first event of death or PD. Tumor response was assessed by the IRF according to RECIST v1.1. Disease progression or PD was defined as ≥20% increase in sum LD in reference to the smallest on-study sum LD, or the appearance of new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.
- Percentage of Participants With Death or Disease Progression as Assessed by the Investigator According to RECIST v1.1 [ Time Frame: Baseline until confirmed disease progression or death, whichever occurred first (assessed at every 9 weeks for the first 12 months, thereafter every 12 weeks until data cutoff date 04 July 2016, up to maximum length of follow-up of 23.52 months) ]Tumor response was assessed by the investigator according to RECIST v1.1. Disease progression or PD was defined as ≥20% increase in sum LD in reference to the smallest on-study sum LD, or the appearance of new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The percentage of participants who died or experienced PD was reported.
- PFS as Assessed by the Investigator According to RECIST v1.1 [ Time Frame: Baseline until confirmed disease progression or death, whichever occurred first (assessed at every 9 weeks for the first 12 months, thereafter every 12 weeks until data cutoff date 04 July 2016, up to maximum length of follow-up of 23.52 months) ]PFS was defined as the time from start of treatment to the first event of death or PD. Tumor response was assessed by the investigator according to RECIST v1.1. Disease progression or PD was defined as ≥20% increase in sum LD in reference to the smallest on-study sum LD, or the appearance of new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.
- Percentage of Participants With a Confirmed Objective Response of CR or PR as Assessed by the Investigator According RECIST v1.1 [ Time Frame: Baseline until confirmed disease progression or death, whichever occurred first (assessed at every 9 weeks for the first 12 months, thereafter every 12 weeks until data cutoff date 04 July 2016, up to maximum length of follow-up of 23.52 months) ]Tumor response was assessed by the investigator according to RECIST v1.1.
