Brief Summary

The purpose of this study is to determine the concentration of 31001074 in blood samples from healthy volunteers who have been administered 31001074 and paroxetine.

Detailed Description

This is an open-label (both volunteer and study physician will know the identity of study treatment) pharmacokinetic study to determine the effects, if any that multiple 20-mg doses of paroxetine have on the concentration of a single dose of study drug (referred to as 31001074) in the bloodstream after paroxetine and 31001074 are administered orally (by mouth) to healthy adult volunteers. Paroxetine is an approved drug used to treat patients with psychiatric disorders and 31001074 is a drug that is currently under development for potential uses in the treatment of patients with nervous system disorders. Approximately 14 healthy volunteers will participate in the study for approximately 45 days (includes a screening period of up to 29 days to determine eligibility and a 16 day treatment period). Volunteers will be required to stay overnight at the study center during the 16-day treatment period. During the 16-day treatment period, volunteers will receive 2 doses of 31001074 and 12 doses of paroxetine. At Screening, a blood sample will be collected from all volunteers for pharmacogenomic analysis (ie, genetic testing) to identify volunteers genetically-determined to have high activity of an enzyme (CYP2D6) that is involved in the processing of 31001074 by the body. Additional blood samples will be obtained from volunteers at protocol-specified time points during the study to determine the concentration of 31001074 and paroxetine in plasma (the colorless portion of blood). Safety will be evaluated during the study by monitoring adverse events (side effects) reported and findings from clinical laboratory tests, vital signs measurements, electrocardiograms (ECGs), and physical examinations performed. In addition, volunteers will be instructed to report the occurrence of adverse events that are considered by the study physician to be serious (as defined by the protocol) for up to 30 days after the administration of the last dose of study drug. A single dose of 31001074 will be administered on Day 1 and Day 13 (total 2 doses). Paroxetine will be administered once daily from Days 4 through 15 (total 12 doses). All doses, including 31001074 and paroxetine will be administered at the same time (approximately 8 am), except on Day 13, when paroxetine will be administered 30 minutes (approximately 7:30 am) before the administration of 31001074.
