Real Time fMRI & Quitting Smoking

Status Completed

Clinical Trial Summary

This study will examine how real-time functional magnetic resonance imaging (rt-fMRI) feedback can be used to modulate brain activation in the context of smoking cues in order to resist craving. Participants will complete a total of three fMRI scanning sessions with a cue suppression task with or without neurofeedback training (NFT). Participants will be randomized to an active group (active NFT) or a control group (no NFT) during the scanning sessions. At the end of the third session, all participants will complete a validated smoking lapse laboratory paradigm to evaluate effects of NFT on smoking behavior.

Clinical Trial Description

Smoking is the greatest preventable cause of mortality and a significant economic burden. Even with the best available treatments, most smokers relapse within days or weeks after a quit attempt. Nicotine replacement therapy, the most widely used pharmacotherapy, yields end of treatment quit rates of <25% suggesting that managing nicotine withdrawal is not sufficient. A smoker's response to smoking cues is one factor that increases risk of relapse. This study will examine how real-time functional magnetic resonance imaging (rt-fMRI) feedback can be used to modulate brain activation in the context of smoking cues in order to resist craving. First, we will conduct a pilot study in 12 smokers for technical development and to evaluate the feasibility of the proposed study procedures. Participants will complete a total of three fMRI scanning sessions with a cue suppression task with or without neurofeedback training (NFT). Participants will be randomized to an active group (active NFT) or a control group (no NFT) during the scanning sessions. At the end of the third session, all participants will complete a validated smoking lapse laboratory paradigm to evaluate effects of NFT on smoking behavior. Upon successful completion of the technical development phase, we will proceed to a proof-of-concept phase, which will recruit 72 smokers to evaluate the efficacy of NFT for smoking behavior. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
