NCT ID: NCT00595868 Completed - Nicotine Dependence Clinical Trials

Efficacy of Varenicline in Ambivalent Smokers

Start date: March 2008
Phase: Phase 2
Study type: Interventional

The purpose of this study is to test whether Varenicline can help ambivalent smokers (those who are interested in quitting at some point in the future but have no current plans to quit) to reduce their smoking and eventually quit.

NCT ID: NCT00589277 Completed - Smoking Clinical Trials

Message Framing for Telephone Quitline Callers

Start date: August 2007
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this study is to compare gain-framed counseling + gain-framed materials" to standard care Quitline counseling + standard print materials. The investigators hypothesize that gain-framed counseling + gain-framed materials group will produce higher abstinence rates than standard care counseling and standard care information. The data in this study will be used to determine effect size estimates for a large scale study.

NCT ID: NCT00578669 Completed - Depression Clinical Trials

Sequential Use of Fluoxetine for Smokers With Elevated Depressive Symptoms

Start date: April 2008
Phase: Phase 3
Study type: Interventional

The primary purpose of this study is to determine whether, among smokers with elevated depressive symptoms, sequential antidepressant pharmacotherapy with fluoxetine (20 mg) begun 8 weeks prior to and extended throughout standard smoking cessation treatment with transdermal nicotine patch (ST-TNP) will result in superior short-and long-term smoking cessation outcomes compared to sequential pharmacotherapy with placebo medication combined with ST-TNP. The secondary aim of the study is to test the hypothesis that, among smokers with elevated depressive symptoms, sequential treatment with fluoxetine will result in lower levels of depressive symptoms and negative mood and higher levels of positive mood immediately prior to and throughout the course of smoking cessation treatment relative to the placebo condition.

NCT ID: NCT00571805 Withdrawn - Nicotine Dependence Clinical Trials

Study of Varencline Effects on Cigarette Smoking Reward and Craving During a Model of Brief Quit Attempt

VarenSmoke
Start date: September 2007
Phase: Phase 1/Phase 2
Study type: Interventional

Study of varenicline 2.0 mg/day treatment for 2 weeks with smoking test done in laboratory on Day 8 and a 1 week quit attempt from Day 8-14.

NCT ID: NCT00567320 Completed - Nicotine Dependence Clinical Trials

Efficacy of Varenicline in Methadone-Stabilized Cocaine Users

Start date: March 2007
Phase: N/A
Study type: Interventional

Cocaine addiction continues to be an important public health problem in the US with a significant cost to the individual and society. Among substance abusers, cocaine use has been recognized as a significant problem especially in methadone-maintenance patients. In several studies, rates of cocaine use have been reported to range from 30 to over 60 percent of those in methadone maintenance programs (Condelli et al. 1991; Hunt et al. 1984; Kidorf and Stitzer 1993; Kosten et al. 1988). In these patients, cocaine use seems to be a predictor of poor clinical outcome (Hartel et al. 1995; Kosten et al. 1987a). The development of effective pharmacotherapies for cocaine use disorders, especially in the opioid-dependent population is of great importance. Unfortunately, such effective pharmacotherapies do not exist. 1. To determine the safety and tolerability of varenicline in cocaine-using methadone-stabilized subjects. 2. To determine if varenicline is efficacious in reducing cocaine-use in methadone-stabilized subjects.

NCT ID: NCT00563563 Completed - Obesity Clinical Trials

A Study of Naltrexone SR/ Bupropion SR in Overweight and Obese Subjects Who Are Nicotine-Dependent

Start date: October 2007
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine whether a combination of naltrexone SR and bupropion SR is safe and effective in the treatment of nicotine-dependence in overweight and obese subjects.

NCT ID: NCT00511134 Terminated - Insomnia Clinical Trials

Study of Lunesta Versus Placebo for Sleep Problems Related to Smoking Cessation and Zyban

Start date: April 2007
Phase: Phase 4
Study type: Interventional

Objectives: The primary objective of this study is to determine the efficacy of eszopiclone at treating sleep problems related to withdrawal from nicotine in healthy smokers attempting smoking cessation. Sleep disturbances are a significant problem for smokers who are trying to quit smoking. Smokers may be more likely to have sleep problems and both nicotine withdrawal and agents used to aid smoking cessation (e.g., pharmacotherapies) may disrupt sleep. Lunesta (eszopiclone) is a medication that has been approved by the FDA to treat insomnia. Eszopiclone's efficacy for treating insomnia makes it a promising agent for treating nicotine withdrawal-related symptoms of sleep disturbance. This study will be 7 weeks duration. All participants will begin taking Zyban at the beginning of week 1 and will be asked to try to quit smoking at the beginning of week 2. Participants will also begin to take Lunesta or matched placebo (3 mg qd x 6 weeks) on the target quit date at the beginning of week 2. All subjects will receive eight (8) weekly sessions of brief individual supportive smoking cessation counseling. Hypothesis: It is hypothesized that significantly fewer sleep problems will be reported by participants taking Lunesta as compared to placebo. Specifically, it is expected that participants taking Lunesta will report less difficulty falling and staying asleep, higher sleep quality, and less insomnia-related fatigue and distress than participants taking placebo.

NCT ID: NCT00508560 Terminated - Nicotine Dependence Clinical Trials

Contingency Management for Smoking Cessation Among Veterans With Psychotic Disorders

Start date: July 2007
Phase: N/A
Study type: Interventional

This study examines the use of contingent incentives to increase attendance at smoking cessation treatment sessions by smokers with schizophrenia and other psychoses who want to quit smoking. We hypothesize that participants randomized to receive contingent rewards for group attendance will attend more treatment sessions than those in the control group.

NCT ID: NCT00502216 Completed - Smoking Clinical Trials

Naltrexone and Varenicline: Weight Gain and Tolerability in Cigarette Smokers

Start date: July 2007
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this study is to determine whether the combination of naltrexone (Depade) and varenicline (Chantix) minimizes post-smoking cessation weight gain and how well the combination is tolerated.

NCT ID: NCT00497068 Completed - Nicotine Dependence Clinical Trials

Tobacco Use in Opioid Agonist Treated Pregnant Women

ROSE
Start date: January 2005
Phase: Phase 2/Phase 3
Study type: Interventional

The primary objective of the proposed study is to evaluate the efficacy of tobacco abstinence-contingent voucher incentives versus non-tobacco abstinence-contingent incentives for reducing or eliminating tobacco use during pregnancy in methadone treated women. In addition, the impact that this intervention has in reducing the incidence and severity of methadone associated neonatal abstinence syndrome will also be examined.
