About this study

The overall goal of this research is to increase our understanding of the role of individual genetic differences in response to bupropion treatment and the psychobiological mechanisms by which genetic and treatment factors interact in the smoking cessation process. The ultimate objective is to provide information necessary to match bupropion vs. behavioral counseling cessation treatment to those smokers with the greatest need and likelihood of benefit. This study is a double-blind randomized placebo-controlled clinical trial of bupropion HCL (brand name Zyban) in adult male and female smokers. The factorial design includes one treatment factor (bupropion 300 mg/day + counseling vs. placebo + counseling) and several subject factors (e.g. genotype, personality). Smoking history, psychological status will be assessed at baseline and blood will be drawn for genotyping. Bupropion or placebo will be delivered over a 10-week treatment period and subjects will be instructed to quit smoking after two weeks of medication (week 3 of treatment). All subjects will also receive a 7-week group behavioral smoking cessation treatment (over an 11 week period). This study may yield information that will help clinicians identify the most effective smoking cessation treatment for a particular patient, based on his/her background.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing zyban in people with Smoking Cessation, run by National Institutes of Health (NIH) 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 1 inclusion and 1 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: finished, as of the sponsor's last update on 11 Jan 2017. 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 phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Continuous abstinence: measured at end of treatment and at 6- and 12- months after cessation.. 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 NCT00322205, which also lists 11 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 11 Jan 2017.
