PFS is defined as the time from date of first dose of study drug until the date of objective PD or death due to any cause, whichever occurs first. PD defined as a ≥20% increase in the sum of the longest diameter (LD) of target lesions using as reference the smallest sum LD since baseline or ≥1 new lesions. Participants who died without PD were considered to have progressed on the date of death. Participants who were alive and without PD were censored at the time of the last objective tumor assessment. Participants who did not progress and are subsequently lost to follow-up were censored at the date of their last objective tumor assessment before loss to follow-up. Participants who progressed or died after ≥2 missed tumor assessment visits were censored at the date of their last objective tumor assessment before missed assessments. Participants who begin a new anticancer therapy were censored at the date of their last objective tumor assessment before initiation of new therapy.
