About this study

Official title: Phase II Randomized, Double-Blind Trial of Bupropion Versus Bupropion + Naltrexone for Smoking Cessation

The purpose of this study is to compare the effects of bupropion + placebo to bupropion + naltrexone as treatments to help smokers quit.

Read the detailed description

The purpose of this study is to compare the effects of bupropion + placebo to bupropion + naltrexone as treatments to help smokers quit. Bupropion is an FDA-approved medication for smoking cessation that is believed to provide relief from craving and withdrawal through promotion of two neurotransmitter chemicals, dopamine and noradrenaline. Naltrexone is an FDA-approved medication for the treatment of opiate and alcohol dependence, that appears to function through blocking certain opiate receptors in the brain. It is expected that bupropion + naltrexone will produce higher smoking quit rates than bupropion + placebo. Bupropion alone is effective in alleviating some nicotine withdrawal complaints and craving for nicotine. However, bupropion does not reduce the rewarding effects of slips to smoking. Naltrexone alone is not generally effective as a smoking cessation medication, but it does help to reduce the rewarding effects of slips to smoking. Thus, it may help to prevent full relapse to smoking. In addition, naltrexone can help to reduce craving for cigarettes. It is hypothesized that the differing complementary actions of the two drugs will help smokers more than bupropion alone. In addition to examining smoking quit rates, the proposed study will also look at psychological processes that change during smoking cessation including, nicotine withdrawal, nicotine craving, mood, impulsivity, and attention

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Bupropion and Bupropion + Naltrexone in people with Tobacco Use Disorder, run by University of Minnesota at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 3 Dec 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Marc E Mooney, Ph.D. (612-273-9732, moon0078@umn.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Biochemically-verified point-prevalence abstinence (time frame: 7, 11, 16, and 30 weeks post-quit). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00419731, which also lists 21 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2009.
