Interventions

• Atezolizumab — DRUG
  Arms A and B Atezolizumab will be administered at a dose of 840 milligrams (mg) prior to RO6874281 administration as an intravenous (IV) infusion on Days 1, 15, 29, and once in 2 weeks from Day 29 onwards. Doses in the extension part will be based on the maximum tolerated dose determined in the escalation part. Arms C and D Atezolizumab will be administered at a dose of 1200mg as it is a Q3W schedule
• Bevacizumab — DRUG
  Arms A and B Bevacizumab will be administered at a dose of 10 milligrams per kilogram (mg/kg) after the atezolizumab administration, and prior to RO6874281 administration as an IV infusion on Days 15, 29, and once in 2 weeks from Day 29 onwards. In Arm D, Bevacizumab will be administered at a dose of 15mg/kg on Day 8 of Cycle 2 and on Day 8 of each consecutive cycle.
• RO6874281 — DRUG
  Arms A and B RO6874281 will be administered as an IV infusion on Days 1, 8, 15, 22, and 29, and once in 2 weeks from Day 29 onwards. Starting dose of RO6874281 will be 5 mg, and will be increased subsequently. Doses in the extension part will be based on the maximum tolerated dose determined in the escalation part. In Arms C and D, RO will be administered on Q3W schedule at the dose defined in the dose escalation part

Study Details

This is an open-label, multi-center, randomized, Phase 1b, adaptive, clinical study to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary therapeutic activity of RO6874281 in combination with atezolizumab with/without bevacizumab in participants with unresectable advanced and/or metastatic RCC. The study will consist of a dose-escalation part and an extension part.

Arms

• Experimental: Escalation Part (Arm A): Atezolizumab, RO6874281
  Participants will receive RO6874281 in combination with atezolizumab once a week for 4 weeks followed by once every 2 weeks afterwards until disease progression, unacceptable toxicities, or withdrawal of consent, or as long as the participant experiences clinical benefit, or if the participant has complete response (CR), treatment may be discontinued and reintroduced if progressive disease (PD), for a maximum duration of 24 months.
• Experimental: Escalation Part (Arm B): Atezolizumab, Bevacizumab, RO6874281
  Participants will receive RO6874281 in combination with atezolizumab and bevacizumab until disease progression, unacceptable toxicities, or withdrawal of consent, or as long as the participant experiences clinical benefit, or if the participant has CR, treatment may be discontinued and reintroduced if PD, for a maximum duration of 24 months.
• Experimental: Extension Part (Arm A): Atezolizumab, RO6874281
  Based on the maximum tolerated dose or recommended dose as determined in the dose-escalation part, participants will receive RO6874281 in combination with atezolizumab once a week for 4 weeks followed by once every 2 weeks afterwards until disease progression, unacceptable toxicities, or withdrawal of consent, or as long as the participant experiences clinical benefit, or if the participant has CR, treatment may be discontinued and reintroduced if PD, for a maximum duration of 24 months. Note: no new participants are being enrolled in the arm at this time.
• Experimental: Extension Part (Arm B): Atezolizumab, Bevacizumab, RO6874281
  Based on the maximum tolerated dose or recommended dose as determined in the dose-escalation part, participants will receive RO6874281 in combination with atezolizumab and bevacizumab once a week for 4 weeks followed by once every 2 weeks afterwards until disease progression, unacceptable toxicities, or withdrawal of consent, or as long as the participant experiences clinical benefit, or if the participant has CR, treatment may be discontinued and reintroduced if PD, for a maximum duration of 24 months. Note: no new participants are being enrolled in the arm at this time.
• Experimental: Extension Part (Arm C): Atezolizumab, RO6874281
  Based on the maximum tolerated dose or recommended dose as determined in the dose-escalation part, participants will receive RO6874281 in combination with atezolizumab once every 3 weeks until disease progression, unacceptable toxicities, or withdrawal of consent, or as long as the participant experiences clinical benefit, or if the participant has CR, treatment may be discontinued and reintroduced if PD, for a maximum duration of 24 months. Note: no new participants are being enrolled in the arm at this time.
• Experimental: Extension Part (Arm D): Atezolizumab, Bevacizumab, RO6874281
  Based on the maximum tolerated dose or recommended dose as determined in the dose-escalation part, participants will receive RO6874281 in combination with atezolizumab and bevacizumab once every 3 weeks until disease progression, unacceptable toxicities, or withdrawal of consent, or as long as the participant experiences clinical benefit, or if the participant has CR, treatment may be discontinued and reintroduced if PD, for a maximum duration of 24 months. Note: Arm D is closed for future enrollment

Primary Outcome Measure

Percentage of Participants with Dose-Limiting Toxicities (DLTs) [ Time Frame: Arm A: It ends one week after the second administration of RO6874281 + atezolizumab Arm B: one week after the first administration of RO6874281 + atezolizumab + bevacizumab ]
