About this study
Official title: Role of Metabolites in Nicotine Dependence (4)
The purpose of this study is to determine the effects of cotinine with or without a transdermal nicotine replacement on tobacco withdrawal symptoms.
Read the detailed description
Previous studies have shown that cotinine, a metabolite of nicotine, antagonizes some of the effects of nicotine. One study showed that nicotine eliminates some of the beneficial effects of the nicotine patch in reducing withdrawal symptoms. The purpose of this study was to replicate and extend these findings and examine the effects of various doses of cotinine base compared placebo on withdrawal symptom as well as drug preference among abstinent smokers while using the nicotine patch. We hypothesized that cotinine will reduce the beneficial effects of the nicotine patch in reducing withdrawal symptoms and that placebo will be preferred over cotinine during the forced drug choice period.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Cotinine fumarate in people with Tobacco Use Disorder, run by National Institute on Drug Abuse (NIDA) 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 1 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 12 Jan 2017. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Subjective effects. The study lists 3 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 NCT00000296, 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 12 Jan 2017.
