Pharmacokinetics of Tasimelteon Alone and in Combination With CYP1A2 Inhibitor, Fluvoxamine

Completed · Phase 1

Conditions studied: Healthy Volunteers

In brief

The purpose of this research study is to evaluate whether administration of a CYP1A2 inhibitor affects the single-dose pharmacokinetics of tasimelteon and its metabolites. The safety and tolerability of tasimelteon will also be assessed throughout the study.
