About this study

Official title: Pilot Study on Varenicline in Light and Intermittent Smokers

The goal of this study is to assess varenicline vs. placebo for its effect on decreasing cue reactivity in light and intermittent smokers.

Read the detailed description

The study will consist of randomization to receive either varenicline or placebo over 6 weeks and include 5 study visits. Participants are offered an optional additional 6 weeks of active varenicline. Cue reactivity will be assessed in both a lab-based setting (viewing series of images and rating cravings) and in a real-world setting (text-based daily interaction).

Being tested
Varenicline, Placebo oral tablet
Medical subject headings
Smoking Cessation, Smoking

What is being measured

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

  1. Change in Self-Reported Craving Level Via Lab-Based Cue Reactivity

    Participants were asked to self-report craving level to smoke on a scale of 1-10 with 1 corresponding to no craving and 10 corresponding to intense craving. Self-reported craving level was requested following presentation of multiple images on a screen over a 20 minute period. Four types of images were presented - neutral affect, negative affect, smoking and social images.

    Measured: Baseline, Visit 4 (week 6)

Secondary outcomes (5)
  1. Change in Self-Reported Craving Level Via Real-World Cue Reactivity

    Craving level in "real world" situations was assessed through electronic momentary assessment (EMA). Participants were instructed to send a text to the study team each time they experienced craving to smoke a cigarette. Self-report craving level to smoke was reported on a scale of 1-10 with 1 corresponding to no craving and 10 corresponding to intense craving.

    Measured: Baseline, Visit 4 (week 6)

  2. Changes in Smoking

    7-day point prevalence smoking abstinence. This will be measured through self-reported daily smoking diaries and daily text messaging.

    Measured: Screening visit, Visit 4 (week 6)

  3. Medication Adherence

    Medication adherence is measured by composite self-reported diaries and daily text messaging responses.

    Measured: Screening visit, Visit 4 (week 6)

  4. Medication Tolerance by Self-Reported Side Effects

    Self-reported side effects (open ended survey questions) with a ranking scale of 1-2 (mild), 3-5 (moderate), and 6-7 (severe). Any side effect 3 or greater will be reviewed by a study medical provider.

    Measured: Up to 12 weeks

  5. Changes in Smoking Abstinence

    7-day point prevalence smoking abstinence confirmed by CO <7ppm. This will be measured through biochemical confirmation (CO breath test).

    Measured: Screening visit, Visit 4 (week 6)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Varenicline in people with Smoking Cessation and Smoking Behaviors, run by Duke 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 8 inclusion and 14 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 11 May 2021. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 May 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in Self-Reported Craving Level Via Lab-Based Cue Reactivity (time frame: Baseline, Visit 4 (week 6)). 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 11 May 2021.
