About this study

This study will examine how abstinence-induced brain changes contribute to smoking cessation outcomes in treatment-seeking smokers.

Read the detailed 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. To improve quit rates significantly, a more refined mechanistic understanding is needed. Neuroimaging can identify mechanisms underlying behavior change beyond self-report and behavioral measures. Functional magnetic resonance imaging (fMRI) studies show that brief (e.g., 24 hr.) abstinence from smoking produces working memory deficits associated with reduced neural activity in cognitive control circuits. This study will examine how abstinence-induced brain changes contribute to clinical outcomes in treatment-seeking smokers. Using a validated fMRI abstinence challenge paradigm, 200 treatment-seeking smokers will complete two 1-hour pre-treatment fMRI scans: after smoking satiety and after 24 hours of confirmed abstinence. Approximately 50% of participants will complete the smoking session first, followed by the absence session, and the remainder will complete the opposite order (counterbalanced). The investigators will examine brain responses during the performance of tasks probing working memory. Participants will then set a target quit date, receive smoking cessation counseling, and be monitored for 6 months to assess time to relapse using a validated smoking relapse protocol.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Standard smoking cessation counselingBehavioural

    Participants will discuss reasons for quitting, the model of smoking as a learned habit, triggers for smoking, and trigger management; receive brief training in how to manage withdrawal symptoms and relapse prevention counseling and receive the NCI Clearing the Air self-help smoking cessation booklet. The target quit date (TQD) session will be scheduled to occur up to 2 weeks following the pre-quit session. Participants will then meet with a smoking cessation counselor for a 15 minute booster counseling session. During the first week following TQD there will be two monitoring visits to closely monitor abstinence. Weekly thereafter for four weeks, participants will attend a brief booster counseling session.

What is being measured

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

  1. Days to Relapse

    The primary outcome will be the number of days to relapse following the target quit date. Relapse will be confirmed using a conventional SRNT guideline criterion of either a positive biochemical verification of smoking or 7 consecutive days of smoking based on self-report (it is very unlikely that a subject would meet the latter criterion without also meeting the former, given the long half-life of cotinine). The days to relapse will be based upon time from target quit date to the first day of the relapse period. Self-reported daily smoking data will be collected using a validated timeline follow-back method. Self-reported abstinence will be biochemically verified on a weekly basis using urine cotinine (<100ng/ml) and a CO reading of ≤5PPM. Drop-outs will be considered relapsers following the last date of abstinence data provided.

    Measured: 6 months after target quit date

Secondary outcomes (1)
  1. Brain Activation (BOLD Percent Signal Change)

    To measure the effects of acute 24-hour abstinence from smoking on executive function, functional magnetic resonance imaging (fMRI) was utilized to assess the relative importance of dorsolateral prefrontal cortex (left DLPFC, right DLPFC), Medial Frontal/Cingulate Gyrus (MF/CG), Posterior Cingulate Cortex (PCC) and Prefrontal cortex (PFC) blood oxygen dependent (BOLD) signals during working memory task performance. Measurement of BOLD percent signal change range is 0 to 2%. Percent signal change is the difference in fMRI signal between the baseline condition (B) and the task condition (T) and calculated here as: percent signal change = (T-B)/B×100%. Greater percent signal change in the DLPFC, MF/CG, PCC, and PFC is generally associated with better executive function.

    Measured: 24 hours

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?

Days to Relapse (time frame: 6 months after target quit date). 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 NCT02837510, which also lists 1 linked publication.

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 5 Mar 2025.
