Primary Outcome

PFS per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) assessed by BICR was defined as the time from the date of randomization until the date of PD, as defined or death (by any cause in the absence of progression) regardless of whether the participant withdrew from randomized therapy or received another anticancer therapy prior to progression. PD was defined as at least a 20% increase in the sum of diameters of target lesions (TLs), taking as reference the smallest previou
