Asimadoline for the Treatment of Post-Operative Ileus

Phase 2
Terminated
Conditions
Post-Operative Ileus
Interventions
Drug: Placebo
Registration Number
NCT00443040
Lead Sponsor
Tioga Pharmaceuticals
Brief Summary

The purpose of this study is to evaluate the safety and efficacy of asimadoline in patients who have undergone a laparoscopic segmental colectomy and determine whether it reduces the time to recovery of bowel function compared to placebo.

Detailed Description

This randomized, double-blind, placebo-controlled study was designed to evaluate the efficacy and tolerability of two dose levels of asimadoline on the duration of post-operative ileus in subjects undergoing laparoscopic or hand-assisted laparoscopic colon resections. Subjects meeting entry criteria were randomized in a 1:1:1 ratio to receive either asimadoline 1.0 mg, asimadoline 3.0 mg or a placebo. One hundred and fourteen subjects were planned, and in the event that a subject was converted from a laparoscopic surgery to an open surgery (laparotomy), that subject would be discontinued from the trial and followed for safety only. The protocol allowed subjects converted to open procedures to be replaced. The first dose was administered approximately 90 minutes pre-operatively, and subsequent dosing was b.i.d. for up to 10 post-operative doses. Subjects were dosed with study drug only while in the hospital. After discharge, they were followed for an additional 28 days. Total study duration for each patient was approximately 5 to 6 weeks.
