This single-center, open-label, single dose, randomized, two-way cross-over study will evaluate the pharmacokinetics, safety and tolerability of RO4917838 in healthy Chinese volunteers. Subjects will be randomized to receive a single oral dose of either 10 mg or 20 mg RO4917838 and, after a washout period of at least 21 but no more than 35 days, will be re-dosed with the alternative treatment. Anticipated time on study is up to 70 days.
