Progression-Free Survival (PFS): Investigator Assessment [ Time Frame: Baseline until disease progression or death due to any cause (up to 1226 days) ]
Investigator assessed PFS was defined as the time (in months) from the date of enrollment in study to the date of first documented objective tumor progression or death (due to any cause), whichever occurs first in the absence of progression. PFS calculated as (first event date minus date of enrollment plus 1)/30.4. If progression or death was not observed, the participant was censored at the date of the participant's last progression-free tumor assessment prior to the study cut-off date. Progression as per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0 criteria was defined as: greater than or equal to (>=) 20 percent increase in sum of longest diameter (LD) of target lesions taking as a reference the smallest sum of the LD recorded since the treatment started, or the appearance of one or more new lesions and/or unequivocal progression of existing non target-lesions. The analysis was performed by Kaplan-Meier method.
