Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression-free survival (PFS)
Time Frame: Up to approximately two years
Investigator-assessed progression-free survival (PFS) Efficacy is evaluated using the Lugano Efficacy Evaluation Criteria for Malignant Lymphoma (Cheson 2014). PFS is defined as the time from randomization to PD or death due to any cause, whichever occurs first.
Up to approximately two years
End of treatment (EOT)
Time Frame: Up to approximately two years
Tumor assessment data will continue to be collected. Tumor assessment data collected after end of treatment (EOT) will be used. Tumor assessment data collected during the study and after EOT will be included in the PFS analysis (treatment policy strategy).
Up to approximately two years
Systemic antitumor therapy
Time Frame: Up to approximately two years
Use of other systemic antitumor therapy before PD or death (in the absence of PD):Tumor assessment after use of other systemic antitumor therapy will not be included in the analysis. For patients using other anti-tumor therapy before PD or death (in absence of PD), PFS will be censored at the last evaluable tumor assessment before the use of other systematic anti-tumor therapy (hypothetical strategy).
Up to approximately two years
Overall survival (OS)
Time Frame: Up to approximately two years
OS is defined as the time from randomization to death due to any cause.
Up to approximately two years
systematic anti-tumor therapy
Time Frame: Up to approximately two years
OS data will continue to be collected after the other systematic anti-tumor therapy, and the OS data collected before and after other systematic anti-tumor therapy will be included in analysis (treatment policy strategy).
Up to approximately two years
Premature withdrawal from study treatment
Time Frame: Up to approximately two years
OS data will continue to be collected after the patient's premature withdrawal from study treatment, and the OS data collected during the study treatment and after EOT will be included in analysis (treatment policy strategy).
Up to approximately two years
