Study Description

Brief Summary

A Phase 1, Fixed-Sequence, Open-label Study in Healthy Subjects to Estimate the Effects of ITCA 650 on Gastric Emptying and on the Absorption Pharmacokinetics of Each of 4 Commonly Studied DDI Probe Compounds.

Condition or Disease	Intervention/Treatment	Phase
Healthy	Drug: ITCA 650 20/60 mcg/day Drug: Acetaminophen Drug: Atorvastatin Drug: Lisinopril Drug: Warfarin Drug: Digoxin	Phase 1

Detailed Description

Acetaminophen will be use to assess the effect of ITCA 650 on the rate of gastric emptying.

Interactions between ITCA 650 and the medications lisinopril, digoxin, atorvastatin, and warfarin will also be studied.
