Treatment: Drugs - RO6874281
Treatment: Drugs - Pembrolizumab

Experimental: 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.

Experimental: Part II Expansion: RO6874281 + Pembrolizumab - Part II will start once all participants in Part I Cohort 1.1 have completed the observation period. Approximately 34 participants will receive RO6874281 in combination with Pembrolizumab every 3 weeks (Q3W) and will be observed for 2 cycles (ie: 6 weeks).

Experimental: Part III Expansion: RO6874281 + Pembrolizumab - Part III will start once all participants in Part I Cohorts 1.1 and 1.2 have completed the observation period. Approximately 80 participants will be randomised to receive RO6874281 in combination with Pembrolizumab in either a Q3W or QW/Q3W schedule.


Treatment: Drugs: RO6874281
Part I Safety Run in:

Cohort 1.1: RO6874281 will be administered by intravenous (IV) infusion; 10 mg (Q3W) every 3 weeks and will be observed over 2 administration cycles (i.e. 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: RO6874281 will be administered by IV infusion via an induction and maintenance phase; 10 mg (QW) every week for 3 weeks followed by 10 mg (Q3W) every 3 weeks and will be observed over 2 administration cycles (6 weeks) to confirm safety of the proposed dose and schedule to be used in Part III of this study.

Part II Expansion: RO6874281 will be administered by IV infusion; 10 mg (Q3W) every 3 weeks (or lower dose level depending on Part I Cohort 1.1 outcome).

Part III Expansion: RO6874281 will be administered by IV infusion; 10 mg (QW) every week or 10mg (Q3W) every 3 weeks (or lower dose level depending on Part I Cohorts 1.1 and 1.2 outcomes) in either a Q3W or QW/Q3W schedule.

Treatment: Drugs: Pembrolizumab
Part I Safety Run in (Cohorts 1.1 and 1.2): Pembrolizumab will be administered by IV; 200 mg Q3W and will be observed over 2 administration cycles (i.e. 6 weeks).

Part II Expansion: Pembrolizumab will be administered by IV; 200 mg Q3W (or lower dose level depending on Part I Cohort 1.1 outcome)

Part III Expansion: Pembrolizumab will be administered by IV; 200 mg Q3W (or lower dose level depending on Part I Cohorts 1.1 and 1.2 outcomes)
