About this study

Official title: A Randomized Controlled Trial of Varenicline for Adolescent Smoking Cessation

This is a placebo-controlled smoking cessation treatment study for adolescents ages 14-21. After assessment and inclusion into the study, participants will be randomized to receive a 12-week double blind course of varenicline or placebo.

Read the detailed description

The objective of this protocol is to examine the efficacy and safety of varenicline for smoking cessation in adolescents. The guiding design philosophy was to model the adult smoking cessation literature (allowing for indirect comparisons of efficacy in different populations) while fine-tuning some elements specifically geared for adolescents. After assessment and inclusion into the study, participants will be randomized to receive a 12-week double blind course of varenicline or placebo. Participants will provide smoking self-report (cigarettes per day) throughout the study. Biological confirmation with carbon monoxide breathalyzer will occur at all visits, and urine cotinine measurement will occur at key time points (baseline, end of treatment and final post-treatment follow-up). Psychiatric/medical visits will occur weekly throughout active treatment to systematically monitor safety and tolerability. After the 12-week treatment course, participants will return for 3 post-treatment follow-up visits (Week 13, Week 18, and Week 26).

What participants receive

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

  • VareniclineDrug

    Also called Chantix

    participants >55 kg will take varenicline/placebo 0.5 mg once daily for 3 days, titrated to 0.5 mg twice daily for 4 days, titrated to 1 mg twice daily thereafter. Participants ≤55 kg will take varenicline/placebo 0.5 mg once daily for 7 days, titrated to 0.5 mg twice daily thereafter.

  • placeboDrug

    participants >55 kg will take varenicline/placebo 0.5 mg once daily for 3 days, titrated to 0.5 mg twice daily for 4 days, titrated to 1 mg twice daily thereafter. Participants ≤55 kg will take varenicline/placebo 0.5 mg once daily for 7 days, titrated to 0.5 mg twice daily thereafter.

What is being measured

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

  1. Number of Participants With Cotinine-confirmed 7-day Point Prevalence Abstinence at the End of Treatment

    Self-reported 7-day cigarette abstinence, confirmed by urine corinne ≤50 ng/mL at the end-of-treatment (week 12) visit

    Measured: 7 days at end of treatment

  2. Number of Participants Experiencing Treatment-emergent Adverse Events

    Clinician-collected adverse events (regardless of relatedness to medication) occurring at any point after randomization and initiation of treatment.

    Measured: 26 weeks (12 weeks of treatment plus full post-treatment follow-up)

Secondary outcomes (3)
  1. Percentage of Visits With Abstinence During Treatment

    Self-reported between-visit abstinence at weekly visits during treatment (reported as percentage of total possible visits across all participants at which participants self-reported abstinence). Missing data were imputed to non-abstinence.

    Measured: 12 weeks (all of active treatment)

  2. Percentage of Post-treatment Visits With Abstinence

    Self-reported abstinence at post-treatment follow-up visits (reported as percentage of total possible post-treatment follow-up visits at which abstinence in the prior week was self-reported). Missing data were imputed to non-abstinence.

    Measured: One week abstinence at the Week 16 and Week 26 post-treatment follow-up visits

  3. Number of Participants Achieving 7+ Days Abstinence at Any Point During Treatment

    Number of participants achieving 7+ days of self-reported abstinence at any point during active treatment

    Measured: 12 weeks of active treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Varenicline in people with Nicotine Dependence, run by Medical University of South Carolina 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 7 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 1 Jul 2020. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Mar 2019). 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?

Number of Participants With Cotinine-confirmed 7-day Point Prevalence Abstinence at the End of Treatment (time frame: 7 days at end of treatment). The study lists 2 primary outcomes in all. 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 NCT01509547, which also lists 2 linked publications.

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 1 Jul 2020.
