PFS was defined as the time from randomization to the date of first documented PD as determined by the IRF according to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) or death, whichever occurs first. PD was defined as appearance of a new lesion(s), unequivocal progression in non-target lesion(s) or at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest sum on the study including baseline (nadir). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimetres (mm).
OS was defined as the time from randomization to the date of death from any cause.
