About this study

Official title: Examining the Effects of Varenicline on Reward Responses,Cognition, and Tobacco Cues in Adolescent Smokers

This is a pilot project using functional magnetic resonance imaging (fMRI) to examine the influence of varenicline on reward processing, cognitive control, and regulation of craving in adolescent smokers. We hypothesize that adolescent smokers receiving varenicline, when compared with those receiving placebo, will have differential brain responses to anticipation of rewards, during exposure to the Stroop task, and in response to tobacco cues.

Read the detailed description

This is a pilot project using functional magnetic resonance imaging (fMRI) to examine the influence of varenicline on reward processing, cognitive control, and regulation of craving in adolescent smokers. We hypothesize that adolescent smokers receiving varenicline, when compared with those receiving placebo, will have increased activation of the ventral striatum (VS) in response to anticipation of rewards in the Monetary Incentive Delay Task (MIDT), decreased activation of the dorsolateral prefrontal cortex (dlPFC) during exposure to incongruent stimuli in the Stroop task, and reduced activation of the ventral striatum in response to tobacco cues, and increased activation of the dlPFC during regulation of responses to tobacco cues during the Regulation of Craving (ROC) task. The results of this pilot project will have important implications regarding the use of varenicline for treating tobacco dependence and understanding varenicline's neurobiological effects in adolescent smokers.

What is being measured

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

  1. neural responses to the MIDT

    The Monetary Incentive Delay Task (MIDT) will be administered during the fMRI at the end of 14 days of varenicline treatment

    Measured: During MRI following14 days of varenicline treatment

  2. neural responses to the ROC

    The Regulation of Craving (ROC)will be administered during the fMRI at the end of 14 days of varenicline treatment

    Measured: During MRI following14 days of varenicline treatment

  3. neural responses to the Stroop

    The Stroop will be administered during the fMRI at the end of 14 days of varenicline treatment

    Measured: During MRI following14 days of varenicline treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Varenicline in people with Tobacco Use Disorders, run by Yale University 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 5 inclusion and 12 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 3 Feb 2014. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

neural responses to the MIDT (time frame: During MRI following14 days of varenicline treatment). 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?
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 Feb 2014; AzTrials last refreshed its copy on 8 Nov 2026.
