Study Arms:
- Dose-Escalation Cohort: FL (Type: EXPERIMENTAL): Participants with relapsed or refractory FL will receive 18 weeks of induction treatment with polatuzumab vedotin and venetoclax at escalating doses to identify the recommended Phase 2 dose (RP2D) for polatuzumab vedotin and venetoclax when combined with a fixed dose of obinutuzumab. Those who achieve CR, PR, or SD at the EOI will be eligible to receive a 24-month maintenance regimen consisting of 8 months of venetoclax and 24 months of obinutuzumab.
- Dose-Escalation Cohort: DLBCL (Type: EXPERIMENTAL): Participants with relapsed or refractory DLBCL will receive 18 weeks of induction treatment. Venetoclax will be administered at escalating doses to identify the RP2D of venetoclax when combined with fixed doses of polatuzumab vedotin and rituximab. Those who achieve CR or PR at the EOI will be eligible to receive an 8-month consolidation regimen consisting of venetoclax and rituximab.
- Expansion Cohort: FL (Type: EXPERIMENTAL): Participants with relapsed or refractory FL will receive 18 weeks of induction treatment with polatuzumab vedotin and venetoclax at the RP2D identified during the dose-escalation phase, in addition to obinutuzumab. Those who achieve CR, PR, or SD at the EOI will be eligible to receive a 24-month maintenance regimen consisting of 8 months of venetoclax and 24 months of obinutuzumab.
- Expansion Cohort: DLBCL (Type: EXPERIMENTAL): Participants with relapsed or refractory DLBCL will receive 18 weeks of induction treatment. Venetoclax will be administered at the RP2D identified during the dose-escalation phase, in addition to polatuzumab vedotin and rituximab. Those who achieve CR or PR at the EOI will be eligible to receive an 8-month consolidation regimen consisting of venetoclax and rituximab.
