Primary Outcomes

Description: PFS: time from randomization to date of progression of disease (PD) as determined by IRC review as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria or death due to any cause, whichever occurred first. PD for target lesions: 20% increase in sum of diameters of target measurable lesions above smallest sum observed, with minimum absolute increase of 5 mm; for non-target lesions: unequivocal progression of pre-existing lesions. Overall tumor burden increased sufficiently to merit discontinuation of therapy. In presence of stable disease (did not achieve partial response, complete response or PD) or partial response (>=30% decrease under baseline of sum of diameters of all target measurable lesions, short diameter used in the sum for target nodes, longest diameter used in sum for all other target lesions) in target disease; for new lesions: appearance of any new unequivocal malignant lesion indicated PD.

Measure: Progression Free Survival (PFS) Based on Independent Radiologic Central (IRC) Review

Time: Day 28 of Cycle 1, Cycle 2 then every 8 weeks until disease progression or death due to any cause, whichever occurred first (up to 48 months)
