What was measured

DOR=first occurrence of CR/PR to disease progression/relapse/death per PET-CT/CT, per IRC per MLRC.CR per PET-CT=score 1/2/3 with/without a residual mass on 5-PS for LN and ELS;1=no UT\> background; 2=UT≤mediastinum;3=UT\>mediastinum but ≤liver;4=UT moderately\>liver;5=UT\>than liver \&/or new lesions;bone marrow morphology=no evidence of FDG-avid disease, normal;if indeterminate IHC negative.PR per PET-CT=score of 4/5 with reduced UT compared to BL \& residual mass of any size at interim for LN \& ELS;residual UT\>UT in normal bone marrow but\<than BL. CR per CT=target nodes/nodal masses regressed to ≤1.5cm in LDi no ELS of disease for LN \& ELS, no non-measured lesion, organ enlargement regressed to normal; bone marrow=normal morphology; if indeterminate, IHC negative. PR per CT= ≥50% decrease SPD of 6 target measurable LN and extranodal sites, absent/normal/regressed but no increase in non-measured lesions, spleen ≥50% in length beyond normal involvement, no new sites of lesions.

Analysis population: ITT population included all randomized participants in DLBCL Cohorts 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. 'Overall Number Analyzed' are the number of participants with data available for analysis.

Groups in this outcome

Arm C (Phase II Randomization): 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 rituximab, 375 mg/m\^2, as IV infusion on Day 1 of Cycles 1 to 6, in combination with pola.

Arm D (Phase II Randomization): BR in DLBCL

Participants with DLBCL received bendamustine 90 mg/m\^2, as IV infusion on Days 2 and 3 of Cycle 1 (each cycle is 21 days), thereafter on Days 1 and 2 of Cycles 2 to 6 in combination with rituximab, 375 mg/m\^2, as IV infusion on Day 1 of Cycles 1 to 6.

Arm F (Phase II Expansion): Pola+BG 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.

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.
