About this study

Official title: Bupropion and Weight Control for Smoking Cessation

The purpose of this study is to determine whether the addition of bupropion (Zyban) to cognitive behavioral therapy (CBT) will enhance longer-term tobacco abstinence in women.

Read the detailed description

Although rates of smoking have declined, the decrease in prevalence has been much less pronounced in women than in men, and women are particularly vulnerable to ongoing smoking-related morbidity and mortality. One important reason for gender differences in smoking cessation is concern about cessation-related weight gain among women, which is associated with poorer cessation outcome. We previously documented that cognitive behavior therapy to minimize weight concerns (CBT) was effective in promoting cessation and controlling weight gain among weight concerned women smokers. The current study is a randomized, double-blind, controlled trial to determine whether the addition of bupropion (Zyban) to CBT (12 sessions over 14 weeks, with 6 booster sessions) will enhance longer-term abstinence. Bupropion was the clear medication of choice for this trial because it is efficacious in promoting smoking cessation, attenuates cessation-related weight gain (particularly in women), and relieves negative mood, which appears more common in weight-concerned women. Four hundred fifty weight concerned women smokers will be randomized to either CBT for weight concerns plus standard cessation or standard smoking cessation only and six months of either bupropion (Zyban) or placebo (2 x 2 design). Primary outcome will be rates of smoking abstinence at 1 year and time to relapse across the four treatment conditions. In addition, we will determine the effects of these treatments on tobacco withdrawal, mood, and weight. Results of this investigation will provide information on the relative efficacy of the CBT intervention and bupropion alone and in combination and the utility of drug and counseling strategies that are specifically tailored for a high-risk population.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Smoking Abstinence

    Women were interviewed using the time-line follow-back method and expired-air carbon monoxide (CO) was collected using a Vitalograph BreathCO monitor. Salivary samples were collected immediately after each assessment visit (1, 3, 6, and 12 mo). A CO reading of 8ppm or less and cotinine level of >15 micrograms/L were used to confirm non-smoking.

    Measured: 3 months

  2. Smoking Abstinence

    Women were interviewed using the time-line follow-back method and expired-air carbon monoxide (CO) was collected using a Vitalograph BreathCO monitor. Salivary samples were collected immediately after each assessment visit (1, 3, 6, and 12 mo). A CO reading of 8ppm or less and cotinine level of >15 micrograms/L were used to confirm non-smoking.

    Measured: 6 months

  3. Smoking Abstinence

    Women were interviewed using the time-line follow-back method and expired-air carbon monoxide (CO) was collected using a Vitalograph BreathCO monitor. Salivary samples were collected immediately after each assessment visit (1, 3, 6, and 12 mo). A CO reading of 8ppm or less and cotinine level of >15 micrograms/L were used to confirm non-smoking.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Bupropion, weight concerns intervention and smoking cessation intervention in people with Tobacco Use Disorder, run by University of Pittsburgh 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 3 inclusion and 9 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 21 Jul 2016. 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 14 Nov 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Smoking Abstinence (time frame: 3 months). The study lists 3 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 NCT00006170, which also lists 2 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 21 Jul 2016.
