QuitFast: Evaluating Transcranial Magnetic Stimulation as a Tool to Reduce

Status Completed

Clinical Trial Summary

Cigarette smoking constitutes the greatest preventable cause of mortality and morbidity in the US. The most critical period for long term success of smoking cessation appears to be in the first 7 days after the quit date. A metaanalysis of 3 pharmacotherapy trials revealed that abstinence during the first 7 days was the strongest predictor of 6 month outcomes (n=1649; Odds ratio: 1.4, P <0.0001; Ashare et al. 2013). Prodigious relapse rates during this first week of smoking cessation are likely due to behavioral and neurobiological factors that contribute to high cue-associated craving and low executive control over smoking. The long term goal of the research is to develop evidence-based transcranial magnetic stimulation protocols to facilitate abstinence during this critical period.

Clinical Trial Description

The investigators will evaluate the efficacy of TMS to the ventromedial prefrontal cortex (vmPFC) to change smoking-related behaviors. The investigators long-term vision is that TBS would be used as an acute intervention enabling individuals to get through the first week after a smoking quit attempt without relapsing, and transition to more sustainable mechanisms of behavioral change (e.g., medication, cognitive behavioral therapy). Aim 1 (Strategy 1): Modulating the limbic system as an approach to treatment: vmPFC TBS. Cigarette smokers will be randomized to receive 10 days of real TBS or sham TBS directed to the vmPFC. Intermittently the desire to smoke, and cigarette self-administration will be assessed. The investigators hypothesize that TBS will: 1) decrease the behavioral smoking measures described above, which will be sustained over a time period sufficient to overcome the initial quit attempt (~7-14 days). The outcomes of the present aims will resolve a critical gap in the investigator's knowledge regarding the efficacy of a promising TMS treatment strategies. These outcomes will be directly translated to a larger longitudinal study evaluating a multi-pronged approach to improving outcomes in traditional pharmacotherapy or behavioral treatments. ;

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.
