What was measured
OR at PRA was defined as the percentage of participants with CR or PR at the PRA, as assessed by the investigator based on MLRC. Per MLRC, CR based on CT was defined as complete radiologic response in lymph nodes and ELS with target nodes/nodal masses regressing to ≤ 1.5 cm in LDi and no ELS of disease organ enlargement regressing to normal; no new lesions; bone marrow normal by morphology, if indeterminate, IHC negative. PR per CT only was defined as partial remission in lymph nodes and ELS with ≥50% decrease in sum of the products of greatest diameters (SPD) of up to 6 target measurable lymph nodes and extranodal sites, absent/normal/regressed but with no increase in non-measured lesions, spleen regressing by ≥50% in length beyond normal it, no new sites of lesions. The analysis was done 6-8 weeks after Cycle 6, Day 1 (each cycle is 21 days for DLBCL cohorts and 28 days for FL cohorts).
Analysis population: ITT population included all randomized participants in Phase II irrespective of whether or not they received the study treatment. As pre-specified in the protocol data reported is combined for Arms G and H. Values have been rounded off to the nearest whole number.
Groups in this outcome

Arm G+H (Phase II NF Cohort): Pola+BR in DLBCL
Participants with DLBCL received pola (lyophilized formulation), 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 rituximab, 375 mg/m\^2, as IV infusion on Day 1 of Cycles 1 to 6, in combination with pola.
