Brief Summary:
This study is a multicenter, open-label study of polatuzumab vedotin administered by intravenous (IV) infusion in combination with standard doses of bendamustine (B) and rituximab (R) or obinutuzumab (G) in participants with relapsed or refractory follicular lymphoma (FL) or diffuse large B-cell lymphoma (DLBCL). The study comprises two stages: a Phase Ib safety run-in stage and a Phase II stage. The anticipated time on treatment is 18 weeks for participants with DLBCL and 24 weeks for participants with FL.

Primary Outcome Measures :
  1. Phase Ib: Percentage of Participants With Adverse Events (AEs) [ Time Frame: From the study start up to the end of the study (up to approximately 84 months) ]
    An AE is 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 can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs were reported based on the National Cancer Institute Common Terminology Criteria for AEs, version 4.0 (NCI-CTCAE, v4.0).

  2. Arm G+H (Phase II NF Cohort): Percentage of Participants With AEs [ Time Frame: From Month 37 to Month 84 (up to approximately 47 months) ]
    An AE is 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 can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as AEs. AEs were reported based on the NCI-CTCAE, v4.0. 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.

  3. Cohort 1a (Phase Ib): Percentage of Participants With Treatment Emergent Anti-Drug Antibodies (ADAs) to Polatuzumab Vedotin [ Time Frame: Baseline up to approximately Month 24 ]
    The number of participants with positive results for ADA against pola at Baseline and at any of the post-baseline assessment time-points were reported. Participants positive at any post-baseline time points were post-baseline evaluable participants determined to have "Treatment-induced ADAs" or "Treatment-enhanced ADA" during the study period. Treatment-induced ADA = negative or missing baseline ADA result(s) and at least one positive post-baseline ADA result. Treatment-enhanced ADA = a participant with positive ADA result at baseline who has one or more post-baseline titer results that are at least 0.60 titer unit (t.u.) greater than the baseline titer result. Treatment emergent ADA is the sum of treatment-induced ADAs and treatment enhanced ADAs. Values have been rounded off to the nearest whole number.

  4. Cohort 1b (Phase Ib): Percentage of Participants With Treatment Emergent ADAs to Polatuzumab Vedotin and Obinutuzumab [ Time Frame: Baseline up to approximately Month 24 ]
    The number of participants with positive results for ADA against pola and obinutuzumab at Baseline and at any of the post-baseline assessment time-points were reported. Participants positive at any post-baseline time points were post-baseline evaluable participants determined to have "Treatment-induced ADAs" or "Treatment-enhanced ADA" during the study period. Treatment-induced ADA = negative or missing baseline ADA result(s) and at least one positive post-baseline ADA result. Treatment-enhanced ADA = a participant with positive ADA result at baseline who has one or more post-baseline titer results that are at least 0.60 t.u. greater than the baseline titer result. Treatment emergent ADA is the sum of treatment-induced ADAs and treatment enhanced ADAs. Values have been rounded off to the nearest whole number.

  5. Arms G+H: (Phase II NF Cohorts): Percentage of Participants With Treatment Emergent ADAs to Polatuzumab Vedotin (Lyophilized) [ Time Frame: From Month 37 to Month 84 (up to approximately 47 months) ]
    The number of participants with positive results for ADA against lyophilized pola at Baseline and at any of the post-baseline assessment time-points were reported. Participants positive at any post-baseline time points were post-baseline evaluable participants determined to have "Treatment-induced ADAs" or "Treatment-enhanced ADA" during the study period. Treatment-induced ADA = negative or missing baseline ADA result(s) and at least one positive post-baseline ADA result. Treatment-enhanced ADA = a participant with positive ADA result at baseline who has one or more post-baseline titer results that are at least 0.60 t.u. greater than the baseline titer result. Treatment emergent ADA is the sum of treatment-induced ADAs and treatment enhanced ADAs. Values have been rounded off to the nearest whole number.

Symptom Severity and Interference According to Therapy-Induced Neuropathy Assessment Score (TINAS) in Arms A-F [ Time Frame: Every week during treatment (up to 24 weeks) and for the first 2 months after treatment, thereafter every month for 10 months or until withdrawal (up to 18 months overall) ]
    The TINAS is an 11-item questionnaire that assesses the severity of neuropathy-related symptoms in the last 24 hours. The 11 items assessed were: hot/burning sensations in hands/feet, sensations pins and needles arms/legs, numbness or tingling in hands/feet, sensations of electric shock, pain when touching cold things, cramps in hands/feet, discomfort when touching things, discomfort skin contact with something, trouble grasping small objects, trouble walking loss feeling legs/feet, difficulty balance loss feeling leg/feet. Each item was scored on a 0-10 scale, with 0 being the symptom is not present, and 10 being the symptom is as bad as the participant can imagine. Higher scores indicate more severe disease. Scores were averaged at each week.
