About this study

the purpose of the study is to see if varenicline in combination with motivational counseling helps homeless cigarette smokers quit smoking.

Read the detailed description

Despite significant declines in cigarette smoking rates among adults in the United States in the last few decades, smoking rates remain high among poor and underserved populations. One underserved group is the 4 million homeless persons in the US among whom cigarette smoking rate is an alarming 70% or more; these rates are 3 times higher than national average. Two of the three leading causes of death among homeless persons, heart disease and cancer are tobacco related.2, 3 Despite very high smoking prevalence and disease burden in this population smoking cessation research have not been extended to the homeless. Recent studies including data from our research team show a considerable degree of readiness to quit smoking by homeless smokers and that nicotine replacement therapy (NRT) plus counseling show promise. However, homeless persons face many challenges that may constitute barriers for them to adhere to smoking cessation treatments even if such treatments have been proven effective in the general population. In order to reduce smoking-related health disparities within this underserved population, it is critical that cessation interventions including strategies to improve treatment adherence be developed to include homeless smokers. The primary aim of this study is to assess the effects of adherence-focused motivational interviewing (MI) to help homeless persons quit smoking.

Recruitment and retention will be enhanced by use of bus passes for transportation, debit cards, attractive intervention materials, collaboration with homeless shelters, and advice from a community advisory board. If successful, this study will provide a model for how to overcome barriers to cancer prevention services among homeless persons. It will also provide the impetus for policy changes directed at increasing homeless persons' access to smoking cessation pharmacotherapy and treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Varenicline plus Motivational Interviewing counseling and Varenicline without counseling in people with Tobacco Use Cessation, run by University of Minnesota 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 4 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 3 Sep 2014. 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?

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?

7-day point prevalence abstinence from smoking (time frame: 6 months after enrollment). 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 NCT00786149, 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 3 Sep 2014.
