Primary Outcome Measures
NameTimeMethod
Objective response rate (ORR)End of treatment visit (6 weeks after last dose on Day 1 of Cycle 6 [Cycle length=21 days]

Percentage of participants with overall response was determined on the basis of investigator assessments according to 2014 Lugano criteria

Secondary Outcome Measures
NameTimeMethod
Complete response rate (CR)End of treatment visit (6 weeks after last dose on Day 1 of Cycle 6 [Cycle length=21 days]

Percentage of participants with complete response was determined on the basis of investigator assessments according to 2014 Lugano criteria.

Progression free survivalBaseline up to data cut-off (up to approximately 2 years)

Progression-free survival was defined as the time from the date of first treatment until the date of the first documented day of disease progression or relapse, using 2014 Lugano criteria, or death from any cause, whichever occurred first.

Duration of responseBaseline up to data cut-off (up to approximately 2 years)

Time from first occurrence of documented CR or PR to disease progression/relapse, or death from any cause for participants with a response of CR or PR. Tumor assessments were performed with PET-CT.
