About this study
Official title: Validation of a Novel Paradigm for Screening Medications for Nicotine Dependence
The goal of the proposed study is to validate an experimental paradigm to assess medication effects on smoking relapse following a brief (3-day) monitored period of smoking abstinence and a programmed cigarette lapse.
Read the detailed description
The proposed human experiment will test the validity of a novel paradigm that may provide a method for distinguishing compounds that are likely to have efficacy from those that are not, before they are tested in more costly large-scale clinical trials. Specifically, in a within-subject (cross-over) behavioral pharmacology investigation of 60 smokers, we will test the effects of varenicline versus placebo on smoking behavior in the natural environment following a 3-day period of monitored abstinence and a programmed cigarette lapse. A positive signal for varenicline effects in this study would provide support for the sensitivity of the paradigm. In addition, following completion of all assessments, participants will be followed in a 13-week open-label varenicline smoking cessation trial to determine whether response to varenicline in the laboratory study predicts clinical response in the open-label trial.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Varenicline in people with Nicotine Dependence, run by University of Pennsylvania 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 1 inclusion and 38 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 17 Aug 2010. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 of abstinence following the programmed lapse (time frame: 7 days). 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 NCT00948649, 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 17 Aug 2010.
