TTR and DOR of responders according to RECIST v1.1 (RES population). TTR was defined as the time from randomization to first CR or PR. DOR was defined as the time from first CR or PR to first PD or death (from any cause), whichever occurred first. Each bar represents the time from randomization to PD or death, or last data collection, in one responding patient. Patients who did not have PD or death and had not received poststudy treatment were considered as having continued response. For patients without PD or death who received poststudy treatment, the date of last diagnostic imaging performed before the start of poststudy treatment was used as the last data collection date. CR, complete response; DOR, duration of response; GEM, gemcitabine; PD, progressive disease; PLD, pegylated liposomal doxorubicin; PR, partial response; RES, response-evaluable set; TTR, time to response.
