  Purpose
This double-blind, randomized, placebo-controlled, 2-Part study will evaluate the pharmacokinetics and safety of RO4917523 in healthy Japanese and Caucasian volunteers. In Part 1, healthy Japanese volunteers will be randomized to receive 2 oral doses of either RO4917523 or placebo, with a washout period of 21 days between dosing. In Part 2, healthy Japanese and Caucasian volunteers will be randomized in cohorts to receive either RO4917523 or placebo orally daily for 14 days.
