A Study of Obinutuzumab, Rituximab, Polatuzumab Vedotin, and Venetoclax in Relapsed or Refractory Follicular Lymphoma (FL) or Diffuse Large B-Cell Lymphoma (DLBCL)

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.

Inclusion Criteria

• Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
• For obinutuzumab + polatuzumab vedotin + venetoclax treatment group, relapsed or refractory FL after treatment with at least one prior chemoimmunotherapy regimen that included an anti-cluster of differentiation 20 (CD20) (anti-CD20) monoclonal antibody (mAb) and for which no other more appropriate treatment option exists, as determined by the investigator
• For rituximab + polatuzumab vedotin + venetoclax treatment group, relapsed or refractory DLBCL after treatment with at least one prior chemoimmunotherapy regimen that included an anti-CD20 mAb and for which no curative option exists as determined by the investigator
• At least one bidimensionally measurable lesion
