The Effects of Naltrexone on Active Crohn's Disease (LDN)
This study is currently recruiting participants.
Verified by Penn State University, April 2008
Sponsors and Collaborators: Penn State University
National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)
The Broad Foundation
Information provided by: Penn State University
ClinicalTrials.gov Identifier: NCT00663117
  Purpose

It is hypothesized that the opioid antagonist naltrexone will improve inflammation of the bowel and quality of life in subjects with active Crohn's disease compared to placebo. In order to test this hypothesis the following specific aims are proposed:

  1. Evaluate the effects of low dose naltrexone compared to placebo on the activity of Crohn's disease by the following end points: Crohn's Disease Activity Index (CDAI), pain assessment, laboratory values (CRP and ESR), endoscopic appearance, histology, and quality of life surveys;
  2. Examine the effects of naltrexone given over 3 months compared to 6 months for durability of response;
  3. Determine the safety and toxicity of low dose naltrexone in subjects with active Crohn's disease, and
  4. Study the mechanism by which naltrexone exerts its effect by measuring plasma enkephalin levels of subjects on therapy.

Purpose statement: The purpose of this study is to evaluate the effects of low dose naltrexone in a blinded placebo controlled study to determine the safety and efficacy of this compound in those with active Crohn's disease.

Further study details as provided by Penn State University:

Primary Outcome Measures:
  • Effects of naltrexone on inflammation of the bowel based upon the following: CDAI scores (Crohn's disease activity index) scores; C-Reactive Protein and ESR; Endoscopic appearance on colonoscopy; Histology biopsies [ Time Frame: 7 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Quality of life: based upon 2 QOL surveys [ Time Frame: seven months ] [ Designated as safety issue: Yes ]
  • Effects of naltrexone on remission of Crohn's disease [ Time Frame: seven months ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 40
Study Start Date: October 2006
Estimated Study Completion Date: October 2009
Estimated Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
A: Placebo Comparator
Subjects will receive placebo for 3 months then be crossed over to active drug for an additional 3 months
Drug: Placebo
Placebo
B: Active Comparator
Group 2 will receive naltrexone 4.5 mg by mouth once a day for 6 months
Drug: Naltrexone
naltrexone 4.5 mg

Detailed Description:

Study design : The study is designed as a double-blind placebo controlled study for 3 months followed by a pseudo cross-over such that all subjects receiving placebo the first 3 months will receive active drug the second 3 months and all receiving naltrexone the first 3 months remain on the drug the last 3 months of this 6 month study.
