Efficacy of Naltrexone in Women's Smoking Cessation

University of Chicago·interventional·Posted Dec 29, 2005·Updated Mar 23, 2023

In Brief

A Phase 2 clinical trial evaluating Naltrexone (drug) and Placebo (for Naltrexone) for Smoking and Smoking Cessation. Completed, enrolled 333 participants across 1 site.

Detailed Summary

The purpose of the proposed study is to conduct a randomized, double-blind clinical trial to compare adjunct treatment with 50 mg oral naltrexone vs. placebo in conjunction with standard smoking cessation treatment with nicotine patch and counseling. Hypotheses: 1. Naltrexone will improve smoking cessation quit rates, as measured at the end of active treatment (3 months) and during long term follow up (1 year). 2. Weight and smoking-related variables (i.e., less weight gain, as well as reduced craving and withdrawal) will be important factors by which naltrexone improves smoking cessation outcome. 3. These effects are predicted to be stronger in women compared to men.
