A Study of Atezolizumab in Combination With Either Obinutuzumab Plus Bendamustine or Obinutuzumab Plus (+) Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (CHOP) in Participants With Follicular Lymphoma (FL) or Rituximab + CHOP in Participants With Diffuse Large B-Cell Lymphoma (DLBCL)

Summary

This Phase Ib/II, open-label, multicenter, non-randomized study will evaluate the safety, efficacy, and pharmacokinetics of induction treatment consisting of atezolizumab in combination with either obinutuzumab + bendamustine (Atezo-G-benda) or obinutuzumab + CHOP (Atezo-G-CHOP) in participants with FL and atezolizumab + rituximab + chemotherapy (Atezo-R-CHOP) in participants with DLBCL, followed by post-induction treatment consisting of either atezolizumab plus obinutuzumab (Atezo-G) in participants with FL who achieve a complete response (CR) or partial response (PR) at end of induction (EOI) or atezolizumab alone in participants with DLBCL who achieve a CR at EOI.

Conditions

• Diffuse Large B-Cell Lymphoma, Lymphoma Follicular

Interventions

DRUG

Atezolizumab

Atezo-G-Benda: Atezolizumab 840 milligrams (mg) intravenously (IV) on Days 1 and 15 of Cycles 2-6, during induction treatment, followed by 840 mg IV on Days 1 and 2 of each month, starting with Month 1, during maintenance treatment. Atezo-G-CHOP: Atezolizumab 1200 mg IV on Day 1 Cycles 2-6, during induction treatment, followed by 840 mg IV on Days 1 and 2 of each month, starting with Month 1. Atezo-R-CHOP: Atezolizumab 1200 mg IV on Day 1 Cycles 2-8, during induction treatment, followed by 1200 mg IV on Day 1 of Cycles 9-25.

DRUG

Bendamustine

Bendamustine will be administered at a dose of 90 milligrams per square meter (mg/m\^2) IV on Days 1 and 2 of Cycles 1-6, during induction treatment.

DRUG

Cyclophosphamide

Cyclophosphamide will be administered at a dose of 750 mg/m\^2 IV on Day 1 of Cycle 1-6/8, during induction treatment.

DRUG

Doxorubicin

Doxorubicin will be administered at a dose of 50 mg/m\^2 IV on Day 1 of Cycle 1-6/8, during induction treatment.

DRUG

Obinutuzumab

Atezo-G-Benda: Obinutuzumab will be administered at a dose of 1000 mg IV on Days 1, 8, and 15 of Cycle 1 and 1000 mg IV on Day 1 of Cycles 2-6, during induction treatment, followed by 1000 mg IV on Day 1 of every other month, starting with Month 1, during maintenance treatment. Atezo-G-CHOP: Obinutuzumab will be administered at a dose of 1000 mg IV on Days 1, 8, and 15 of Cycle 1 and 1000 mg IV on Day 1 of Cycles 2-6 during induction treatment, followed by 1000 mg IV on Day 1 of every other month, starting with Month 1 during maintenance treatment.

DRUG

Prednisone

Prednisone will be administered at a dose of 40 mg/m\^2 orally on Days 1-5 of Cycle 1-6/8, during induction treatment. Prednisolone may be given if prednisone is unavailable. The 40 mg/m\^2 dose of prednisone on Day 1 will be replaced by oral corticosteroids given as premedication on Day 1 of Cycle 1 (and subsequent cycles).

DRUG

Vincristine

Vincristine will be administered at a dose of 1.4 mg/m\^2 (maximum 2 mg) IV on Day 1 of Cycle 1-6/8, during induction treatment.

DRUG

Rituximab

Atezo-R-CHOP: Participants with previously untreated DLBCL will receive rituximab at a dose of 375 mg/m\^2 IV on Day 1 of Cycle 1-8, during induction treatment.
