Percentage of Participants With CR at EOI Determined by an Independent Review Committee (IRC) on the Basis of Positron Emission Tomography (PET) and Computed Tomography (CT) ScansPrimary· 6 to 8 weeks after Day 1 of Cycle 6 (up to approximately 23 weeks) (1 cycle=21 days)
CR at EOI was assessed by the IRC according to modified Lugano Response Criteria (MLRC) for Malignant Lymphoma 2014 using PET-CT scan. Per MLRC, CR was defined as complete metabolic response (MR) in lymph nodes and extra lymphatic sites (ELS) with a score of 1, 2, or 3, with or without a residual mass on PET 5-point scale (5-PS), 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 new lesions; no evidence of fluorodeoxyglucose (FDG)-avid disease in bone marrow.

FL Cohorts: Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)Primary· From study start to 24 months after last dose of study drug (approximately 56 months)
An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any new disease or worsening of an existing disease were also considered as AEs. An SAE was defined as any AE that was fatal, life threatening, requires prolonged inpatient hospitalization, resulted in sig

This study will evaluate the safety, efficacy, and pharmacokinetics of induction treatment with obinutuzumab, polatuzumab vedotin, and venetoclax in participants with relapsed or refractory FL, and with rituximab, polatuzumab vedotin, and venetoclax in participants with DLBCL. Participants with FL who achieve complete response (CR), partial response (PR), or stable disease (SD) at the end of induction therapy will receive post-induction treatment with obinutuzumab and venetoclax, and participants with DLBCL who achieve CR or PR at the end of induction (EOI) will receive post-induction treatment with rituximab and venetoclax.
