About this study

Official title: Neurocognitive and Affective Correlates of Tobacco Dependence in Adolescent Smokers and Efficacy and Safety of Bupropion for Treatment of Adolescent Smoking

The purpose of this study is to determine: 1) the short-term clinical efficacy and safety of bupropion for helping adolescent tobacco smokers quit, and 2) The role of withdrawal symptoms in the maintenance of smoking in adolescents.

Read the detailed description

This 10-week study consists of an unassisted (pretrial) acute tobacco withdrawal (AW) phase and a 7-week randomized double-blind placebo-controlled trial of bupropion (300 mg/day) for tobacco dependence. Neuropsychological examinations will be conducted at baseline, during acute withdrawal, and during treatment (incl. early withdrawal) with bupropion. We expect smoking cessation in approximately 25% of the active medication group and significant overall smoking reduction. We postulate that bupropion will also reduce the irritability, depressed mood and anxiety symptoms that typically occur during tobacco withdrawal. We expect to observe optimal cognitive performance, (i.e., attention, memory), and affective state during satiety, impairment during pre-treatment abstinence, and intermediate level cognitive performance in the abstinent active-treatment group. Because limited data are available on cognitive tasks in adolescent smokers, a non-smoking group will be included in order to establish the validity and appropriateness of our paradigm with a normative sample.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Bupropion in people with Tobacco Dependence, run by National Institute on Drug Abuse (NIDA) 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 6 inclusion and 3 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: stopped early, as of the sponsor's last update on 23 Sep 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 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?

The study was stopped early (reason given: PI left NIH). Results are not available in the source record.

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?

Bupropion will be safe and tolerable, increase cessation rates, and reduce smoke and nicotine exposure (time frame: 7 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Sep 2016.
