Time frame
From the first dose date of maintenance therapy to the time of first documented administration of new anti-lymphoma therapy (up to approximately 300 weeks)

What was measured

Time to next anti-lymphoma treatment is defined as the time from the first dose date of maintenance therapy to the time of first documented administration of new anti-lymphoma therapy. Participants without new treatment therapy will be censored at the last visit. Analysis was based on Kaplan Meier estimates.

Analysis population: All randomized participants in Arm A and Arm B, as prespecified in the protocol

Groups in this outcome

Arm A: Lenalidomide + Rituximab

Maintenance Period (18 Cycles): lenalidomide 10 mg once daily on Days 1 to 21 of every 28-day Cycle for Cycles 13 to 30 AND rituximab 375 mg/m2 on Day 1 of every 28-day Cycle for Cycles 13, 15, 17, 19, 21, 23, 25, 27, and 29. Followed by Optional Maintenance Period (up to PD): Lenalidomide 10 mg once daily on Days 1 to 21 of every 28-day Cycle up to PD. This treatment will be at the discretion of the participant and the investigator.

Arm B: Rituximab

Maintenance Period (18 Cycles): participants received rituximab 375 mg/m2 on Day 1 of every 28-day Cycle for Cycles 13, 15, 17, 19, 21, 23, 25, 27, and 29
