About this study

Nicotine replacement therapy (NRT) is a well-tolerated and efficacious smoking cessation treatment, and yet many smokers fail to quit using NRT. Many of these smokers may benefit from prescription treatment alternatives, including Zyban or Chantix. In this study, the investigators propose to develop and evaluate a stepped-care treatment algorithm that would evaluate whether smokers who receive treatment with NRT should be supplemented with Zyban or switched to Chantix only based on: 1) their initial response to NRT; and 2) individual genetic factors found to predict smoking cessation in other studies evaluating these treatments. This study is a continuation of our previous studies showing that abstinence rates can be increased by starting nicotine patch therapy two weeks before the quit date. The investigators will provide pre-cessation NRT to all participants initially. Those who do not show a favorable response on early indicators of success (e.g., smoking in the first week after the target quit-smoking date) will receive "rescue" treatment by having their NRT treatment supplemented with Zyban , by being switched to treatment with Chantix or will remain on NRT (control).

The investigators hypothesize that "Rescue" treatment with Zyban in combination with NRT or Chantix will increase success rates over leaving subjects on NRT when they are NRT insufficient responders, i.e. they have shown an unfavorable response to NRT in the first week pre-quit or the first week post-quit.

What is being measured

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

  1. Continuous 4-week Abstinence From Smoking Between Weeks 8-11 After the Quit Date (Through the End of Treatment)

    A self report of no cigarettes smoked confirmed by expired air carbon monoxide of <=10ppm was the criterion for abstinence.

    Measured: weeks 8-11 after quit date

Secondary outcomes (2)
  1. Abstinence (7 Days) at 6 Months.

    Measured: point abstinence (7 days) at 6 months post-quit date

  2. Continuous Abstinence From Smoking at 6 Months Post Quit.

    Measured: continuous abstinence at 6 months post quit day

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Nicotine Patches, Nicotine patches, then bupropion & nicotine patches (Pre-Quit) and Nicotine patches, then varenicline (Pre-Quit) in people with Smoking Cessation, 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 4 inclusion and 35 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 23 Sep 2013. 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. 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 26 Dec 2012). 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?

Continuous 4-week Abstinence From Smoking Between Weeks 8-11 After the Quit Date (Through the End of Treatment) (time frame: weeks 8-11 after 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 NCT00894166, which also lists 4 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 23 Sep 2013.
