Asimadoline for the Treatment of Post-Operative Ileus

November 30, 2011 updated by: Tioga Pharmaceuticals

A Randomized, Double-Blind, Placebo-Controlled Study Evaluating Asimadoline on the Duration of POI in Subjects Undergoing Laparoscopic/Hand-Assisted Lap Segmental Colonic Resection Secondary to Colon Cancer, Polypectomy or Diverticulitis

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

PLACEBO_COMPARATOR: Placebo
Drug: Placebo
Placebo was provided in coated tablets identical in appearance to asimadoline tablets. Subjects were given 3 tablets of placebo 90 minutes prior to their operation and then 3 placebo tablets b.i.d. for up to 10 post-operative doses.
ACTIVE_COMPARATOR: Asimadoline 1.0 mg
