Safety and Pharmacokinetics Study of HE3286 in Patients With Active, Mild-to-Moderate Ulcerative Colitis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00628433
Recruitment Status : Completed
First Posted : March 5, 2008
Last Update Posted : June 14, 2011
Information provided by:
Harbor Therapeutics

Brief Summary:
The purpose of this pilot, exploratory study is to evaluate the safety, tolerance, pharmacokinetics and potential activity of an investigational agent, HE3286, when administered orally, daily for 28 days to patients with mild-to-moderate ulcerative colitis.

Condition or disease Intervention/treatment Phase
Ulcerative Colitis Drug: Placebo Drug: HE3286 Phase 1 Phase 2

Detailed Description:
HE3286 has a potentially new mechanism of action that may improve the current therapeutic options available to patients with ulcerative colitis. In preclinical experiments, HE3286 has shown activity in animal models of ulcerative colitis. Additionally, HE3286 has shown to have anti-inflammatory activity associated with corticosteroids but without the side effects associated with corticosteroid use, such as immune suppression and bone loss.
