Secondary

MeasureTime frameDescription
Objective Responseup to 56 daysObjective response rate (ORR) as assessed by the investigator
Progression-free survivalUp to 2 yearsProgression-free survival (PFS), defined as the time from the initiation of treatment to disease progression or death as assessed by the independent Central Imaging Review and the Investigator.
