What was measured

PFS was defined as the time randomization or from first study treatment (for obinuzumab arms) to the first occurrence of disease progression, relapse or death, from any cause based on PET-CT or CT only, as determined by the investigators assessment. As pre-specified in the protocol data reported is combined for Arms G and H.

Analysis population: ITT population included all randomized participants in DLBCL Cohorts irrespective of whether or not they received the study treatment.

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.
