Progression-Free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1
Tumor assessments were performed according to RECIST Version 1.1. Disease progression was defined as greater than or equal to (≥) 20 percent (%) increase in sum of largest diameters (LD) of target lesions in reference to the smallest sum of LD on study, in addition to an absolute increase ≥5 millimeters (mm). Disease progression was further defined as the last documented progression determined by the Investigator no later than 1 day before initiation of second-line therapy. Death on study included death from any cause occurring no later than 3 months after the last component of study treatment. PFS was defined as the time from randomization to death or disease progression, whichever occurred first. The median duration of PFS was estimated by Kaplan-Meier analysis and expressed in months. The 95% confidence interval (CI) was computed using the method of Brookmeyer and Crowley.
