Secondary

MeasureTime frame
- OS, defined as the time from randomization until death due to any cause ORR, defined as the percentage of participants with a confirmed PR or better per IMWG - Clinical benefit rate (CBR), defined as the percentage of participants with a onfirmed minimal response (MR) or better per IMWG - DoR, defined as the time from first documented evidence of PR or better until PD per IMWG or death due to any cause among participants who achieve confirmed PR or better
