Study Groups

Part I Safety Run in: RO6874281 + Pembrolizumab

Cohort 1.1 (CPI naive and experienced melanoma participants):

Participants will receive RO6874281 in combination with Pembrolizumab every 3 weeks (Q3W) and will be observed for 2 cycles (ie: 6 weeks) in order to confirm the safety of the proposed dose and schedule that will be used in Part II of this study.

Cohort 1.2 (CPI experienced melanoma participants only):

Participants will receive RO6874281 in combination with Pembrolizumab via an induction and maintenance schedule for RO6874281: QW three times (D1, D8, D15) followed by Q3W dosing (D22 and subsequent). Pembrolizumab is to be administered Q3W, starting on Day 1. Participants will be observed for 2 pembrolizumab cycles (ie: 6 weeks) in order to confirm the safety of the proposed dose and schedule that will be used in Part III of this study.
