Arm && Interventions

Group	Intervention	Description
RO6864018	RO6864018	Asian participants will receive a single oral dose of RO6864018 capsule on Day 1. The first dose escalation cohort will receive a single 400 mg oral dose. Dose will be escalated in subsequent cohorts (up to Cohort 4) up to a maximum of 1600 mg, based on safety, pharmacokinetic, and pharmacodynamic data available from lower dose cohorts. The Cohort 5 will include Caucasian participants who will receive a single 1200 mg (or the highest dose well-tolerated by Asian participants, if lower than 1200 mg) oral dose of RO6864018 capsules on Day 1.
Placebo	Placebo	Participants will receive a single oral dose of placebo matching to RO6864018.
