Objective tumor response includes subjects with CR or PR according to RECIST.

Duration of Clinical BenefitBaseline, Weeks 8, 16, 24, every 12 weeks from Week 24 up to Week 108, and every 24 weeks thereafter until 9 months following LSLV

Time from randomization date to first objective documentation of tumor progression or death due to tumor progression in the absence of previous documentation of tumor progression.

Duration of Objective Response (in Subjects With CR or PR)Baseline, Weeks 8, 16, 24, every 12 weeks beyond 24 up to Week 108, and every 24 weeks thereafter until 9 months following LSLV

Time from the first objective documentation of response until the first objective documentation of tumor progression.

Duration of Long-Term SDBaseline, Weeks 8, 16, 24, every 12 weeks from Week 24 up to Week 108, and every 24 weeks thereafter until 9 months LSLV

Time from start of treatment until the first objective documentation of tumor progression or death due to tumor progression in the absence of previous documentation of tumor progression in subjects with long-term SD.

Time to Tumor ProgressionBaseline, Weeks 8, 16, 24, every 12 weeks beyond Week 24 up to Week 108 and every 24 weeks thereafter until 9 months following LSLV

Time from randomization to first objective tumor recurrence or progression or death due to tumor progression in the absence of previous documentation of tumor progression.

Time to Treatment FailureBaseline, Weeks 8, 16, 24, every 12 weeks from Week 24 up to Week 108, and every 24 weeks thereafter until 9 months following LSLV

Time from randomization to first objective tumor recurrence or progression or death due to any cause or withdrawal from study treatment due to any reason, whichever was the earliest.

SurvivalBaseline, Weeks 8, 16, 24, every 12 weeks from Week 24 up to Week 108, and every 24 weeks thereafter until 9 months following LSLV or death
