This is a single-center, double-blind, placebo-controlled, randomized study in healthy Japanese and Caucasian subjects after administration of single and multiple doses of rasagiline. All subjects will have a screening visit within 28 days of their check-in day (day -1) to confirm eligibility. Eligible subjects will be admitted to the investigational center on study day -1 and their eligibility to participate in the study confirmed. On the morning of day 1, subjects will be randomly assigned to receive a daily dose of 0.5, 1, or 2 mg of rasagiline or placebo at the same time every morning after an overnight fast (of at least 10 hours) on days 1 through 10. Venous blood samples (4 mL each) for pharmacokinetic analysis will be collected at specified time points through 24 hours after study drug administration on day 1 and through 48 hours after study drug administration on day 10. The duration of study participation for each subject will be approximately 6 weeks.
This study is designed to evaluate the pharmacokinetics of rasagiline in healthy Japanese and Caucasian subjects after single and multiple doses of rasagiline.
