Healthy Volunteer
Conditions
Brief summary
This single-center, open-label study will assess the excretion balance, pharmacokinetics and metabolism of oral \[14C\]-labeled RO4917523 in healthy male volunteers. Subjects will receive a single oral dose of \[14C\]-labeled RO4917523 and an intravenous tracer dose of \[13C\]-labeled RO4917523 on Day 1. In-clinic period will be up to 18 Days. Anticipated time on study is up to 15 weeks.
