Active clinical trials for "Tobacco Use Disorder"

Tobacco use remains a significant public health problem and is increasingly prevalent among vulnerable groups. Appalachians have a high prevalence of tobacco use and are at increased risk for tobacco-attributable diseases. The efficacy of a scientifically valid tobacco cessation treatment delivered to Appalachian smokers remains untested. Also, little is known about the association of social-contextual factors that may modify or mediate the success of an intervention. These factors may be of particular relevance among disadvantaged smokers. Geographical patterns of tobacco exposure may also influence one's ability to quit, especially in pro- tobacco regions like Appalachia. The purposes of this application are to: 1) evaluate the efficacy of a lay-led (LL) intervention in promoting long term abstinence from tobacco; and 2) examine the association between 12 month abstinence and selected individual, interpersonal, organizational, neighborhood and community, and societal factors among adult Appalachian tobacco users exposed to a tobacco cessation intervention. A third aim is exploratory and includes the characterization of activity patterns using space-time measures among adult Appalachian tobacco users exposed to a tobacco cessation intervention. Using a group randomized trial design, 707 Appalachian residents from 6 intervention and 6 control counties will be randomly assigned by county to receive the LL intervention or a control condition which includes proactive telephone counseling via the Ohio Quit Line. LL group participants will receive face-to-face counseling, supervised by a county health department nurse, and delivered by a trained lay educator. A county Extension agent will assist with recruitment and retention efforts in this project. Social-contextual factors will be assessed at a baseline interview administered to all participants. Space-time activity geographical patterns of pro- and anti-tobacco exposures, or features, will be described among selected participants in four counties during weeks 1, 6 and 12 of treatment. At end of treatment and 6 and 12 months, LL and control group participants will be reassessed for tobacco use via self-report and cotinine-validation. Secondary analyses will explore differential trends over time between the two arms of the study. In a subset of the sample, pro- and anti-tobacco exposures will be estimated during weeks 1, 6 and 12 of treatment.

The study team will conduct a feasibility, acceptability, and preliminary efficacy trial comparing Learn to Quit-HIV (n=30) to an app based on U.S. Clinical Practice Guidelines only (NCI QuitGuide; n=30) among HIV-positive smokers. Both apps will be integrated with NRT and ongoing HIV clinical care.

The purpose of this study is to examine the effects of rapamycin (sirolimus) versus a placebo, an inactive substance, on responses to smoking cues in individuals with nicotine dependence. Rapamycin (sirolimus) is a FDA-approved antibiotic and immunosuppressive drug that is currently used to (a) prevent organ transplant recipients from rejecting their transplants (b) treat cardiovascular diseases, and (c) treat some forms of cancer. Rapamycin (sirolimus) is not FDA-approved for smoking cessation. The use of rapamycin (sirolimus) in this study is investigational, meaning that the study medication is not a proven treatment for nicotine dependence, however this study will examine the medication's use as a potential future treatment for nicotine dependence.

Chronic Obstructive Pulmonary Disease (COPD) is caused primarily by smoking and smoking cessation is the first-line treatment for slowing disease progression. Despite this, nearly 50% of COPD patients continue to smoke following diagnosis. Smokers with COPD report high rates of co-occurring conditions - nicotine dependence, depression, and anxiety - which serve as barriers to quitting. The current study will pilot test a behavioral intervention designed to target the common psychological factors underlying these co-occurring conditions and foster smoking cessation among COPD patients.

Single-dose pharmacokinetics with two new oral nicotine replacement products and Nicorette® gum.

This study examines the bioequivalence between an oral nicotine replacement product and Nicorette® gum.

This study will test the effectiveness of an Emergency Department (ED) initiated tobacco intervention which includes counseling and medication. Our proposed intervention combines a Brief Negotiated Interview (BNI) with initiation of nicotine patch and gum in the ED, as well as a faxed referral to the state's Smokers' Quitline. A 6 week supply of nicotine patches and nicotine gum are provided to subjects in the intervention arm. Subjects randomized to the control arm will receive a brochure from the state's Smokers' Quitline only. The primary hypothesis is that the intervention will be superior to the control condition in reducing self-reported and biochemically verified 7-day tobacco abstinence at 3 months.

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.

During the 1-year formative phase of a study to develop an integrated treatment for quitting smoking for anxiety-vulnerable HIV+ smokers. During this first phase of the study, start-up activities will include piloting the integrated treatment on a small group of individuals (N = up to 12), obtaining expert consultant and participant feedback, and development of the final treatment manual and procedures. The goal during this phase will be to establish feasibility of treatment delivery, participant acceptability, and potential for a treatment effect before conducting a pilot randomized trial of the treatment. During the two-year pilot RCT phase of the above study, we directly develop and test a novel psychosocial/behavioral and pharmacological smoking cessation intervention for HIV+ smokers with interfering psychological distress.

This is a prospective, double-blind placebo-controlled randomized pilot trial of the preliminary safety and efficacy of bupropion SR in combination with behavioral counseling for smoking cessation during pregnancy.
