Brief Summary

This is a single center, open-label, fixed sequence Phase 1, drug-drug interaction (DDI) study in healthy subjects.

Detailed Description

Following a Screening period, eligible subjects will be enrolled sequentially to one of three cohorts to receive a single dose of probe substrate(s), followed by repeated titrated doses of ecopipam twice daily (BID) (with subjects in Cohort 3 also receiving a single dose of ecopipam and probe substrates on Day 4 prior to titration). After steady-state ecopipam dosing is reached, ecopipam will be co-administered with a single dose of probe substrate(s) (with continuation of ecopipam BID (every 12 h) dosing during the blood sampling period for the respective probe substrates), followed by an ecopipam tapering period and clinic discharge assessments.
