  1. description
    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.
