Overall Population: PFS by IRC Review, Using the Lugano 2014 Criteria, Defined as the Time From Randomization to the First Documented PD, or Death From Any Cause, Whichever Occurred First

What was measured

PD, PET: score 4 (uptake moderately \> liver) or 5 (uptake markedly higher than liver and/or new lesions) for lymph node/extra lymphatic sites with increase in intensity of Baseline uptake and/or new FDG-avid foci consistent with lymphoma at interim/end-of-treatment assessment; new/recurrent FDG-avid foci in bone marrow; new FDG-avid foci consistent with lymphoma versus other etiology in new lesions. PD, CT: abnormal individual node/lesion with LDi \>1.5 cm and increase by ≥50% from the PPD nadir and increase in LDi or SDi from nadir; new/clear progression of preexisting nontarget lesions; new/recurrent splenomegaly and bone marrow involvement; regrowth of previously resolved lesions. New node \>1.5 cm in any axis. New extranodal site \>1.0 cm in any axis; if \<1.0 cm, presence is unequivocal and attributable to lymphoma.

Analysis population: Overall Full Analysis Set. As pre-specified in the Statistical Analysis Plan, the MZL population was considered as a subpopulation of interest, not a main analysis population. The FL and MZL populations were combined for analysis into the Overall population, which was a main analysis population. The 2-sided 95% confidence intervals were calculated using the method of Brookmeyer and Crowley with log-log transformation. Censored participants were included in the analysis.

Groups in this outcome

FL and MZL: Tafasitamab + Rituximab + Lenalidomide

Participants with FL and MZL were randomized to receive tafasitamab 12 mg/kg IV, administered on Days 1, 8, 15, and 22 of Cycles 1 to 3 and on Days 1 and 15 of Cycles 4 to 12. Participants also received oral lenalidomide (including generics) 20 mg QD, administered at approximately the same time every day on Days 1 to 21 of Cycles 1 to 12, and rituximab (including biosimilars) 375 mg/m\^2 IV, administered on Days 1, 8, 15, and 22 of Cycle 1 and on Day 1 of Cycles 2 to 5. A treatment cycle was defined as 28 calendar days.

FL and MZL: Placebo + Rituximab + Lenalidomide

Participants with FL and MZL were randomized to receive placebo 0.9% saline solution IV, administered on Days 1, 8, 15, and 22 of Cycles 1 to 3 and on Days 1 and 15 of Cycles 4 to 12. Participants also received oral lenalidomide (including generics) 20 mg QD, administered at approximately the same time every day on Days 1 to 21 of Cycles 1 to 12, and rituximab (including biosimilars) 375 mg/m\^2 IV, administered on Days 1, 8, 15, and 22 of Cycle 1 and on Day 1 of Cycles 2 to 5. A treatment cycle was defined as 28 calendar days.
