The Effects of Naltrexone in Active Crohn's Disease
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.

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.

contraception (either IUD, oral or deport contraceptive, or barrier plus spermicide),
and willing and able to continue contraception for 3 months after the completion of
the study.
