Brief summary
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.
Interventions
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
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.
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
