What was measured

CR was defined as a complete metabolic response at any time after the start of treatment. Per PET, CR criteria: (1) score of 1, 2, or 3 with or without a residual mass on a 5-point scale for lymph nodes and extralymphatic sites; (2) No evidence of FDG-avid disease in bone marrow; and (3) no new lesions. PET 5-point scale: 1 = no uptake above background; 2 = uptake ≤ mediastinum; 3 = uptake \> mediastinum but ≤ liver; 4 = uptake moderately \> liver; 5 = uptake markedly higher than liver and/or new lesions; X = new areas of uptake unlikely to be related to lymphoma.

Analysis population: FL FDG-avid Set: all randomized participants with FL and with a PET scan at Baseline with a resulting Deauville score of 4 or 5. Participants who did not have a post-baseline PET scan were considered to be "not assessed," but were included in the analysis. The 95% confidence intervals were calculated using the Clopper-Pearson method.

Groups in this outcome

FL: Tafasitamab + Rituximab + Lenalidomide

Participants with follicular lymphoma (FL) were randomized to receive tafasitamab 12 milligrams per kilogram (mg/kg) intravenously (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 once daily (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/meters squared (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: Placebo + Rituximab + Lenalidomide

Participants with FL 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.

MZL: Tafasitamab + Rituximab + Lenalidomide

Participants with marginal zone lymphoma (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.

MZL: Placebo + Rituximab + Lenalidomide

Participants with 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.
