What was measured

CR was assessed by Investigator at PRA according to MLRC. Per MLRC, CR based on PET-CT was defined as complete MR in lymph nodes and ELS with a score of 1, 2, or 3 with or without residual mass, on 5PS where 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 no evidence of FDG-avid disease in bone marrow. Bone marrow is normal by morphology; if indeterminate, IHC negative. As pre-specified in the protocol data reported is combined for Arms G and H. The analysis was done 6-8 weeks after Cycle 6, Day 1 (each cycle is 21 days for DLBCL cohorts) or after final dose of study treatment. Values have been rounded off to the nearest whole number.

Analysis population: ITT population included all randomized participants in Phase II NF Cohort irrespective of whether or not they received the study treatment.

Groups in this outcome

Arm G+H (Phase II NF Cohort): Pola+BR in DLBCL

Participants with DLBCL received pola, 1.8 mg/kg, as IV infusion on Day 2 of Cycle 1 (each cycle is 21 days), and thereafter on Day 1 of Cycles 2 to 6. Participants also received bendamustine 90 mg/m\^2, as IV infusion on Days 2 and 3 of Cycle 1, and thereafter on Days 1 and 2 of Cycles 2 to 6 and obinutuzumab 1000 mg, as IV infusion on Days 1, 8, and 15 of Cycle 1 and on Day 1 of Cycles 2 to 6 in combination with pola.
