Filter by:This project will test whether gemfibrozil, a well-studied medication for high cholesterol, will help people stop smoking nicotine cigarette smoking. The study will also test whether gemfibrozil decrease cravings for cigarette and the desire to smoke.
SUMMARY Rationale: Worldwide, cigarette smoking carries a high mortality. Since the available cessation programs are not effective for all smokers, new strategies are necessary for tobacco control. Primary objective: To investigate whether a 6-week varenicline preloading facilitates smoking reduction and cessation compared with the standard varenicline treatment schedule. Design: Parallel group, double-blind, randomised controlled clinical trial. Participants: Smokers of both sexes from the general population. Methods: Participants will be randomized into two groups of treatment. Subjects in Group A will receive varenicline for six weeks while those in group B will receive placebo for 5 weeks and varenicline for 1 week. During this phase, subjects in both groups will be asked to reduce cigarette smoking by 50 percent. At week 6 all participants will be instructed to stop smoking before receiving 12 weeks of varenicline treatment. Visits will be arranged at randomization, week 4, week 6 (Quit day (QD)) and at week 1, 6, 12, and 24 after QD. Measurements: These will include vital signs, smoking history, spirometry, expired CO, salivary cotinine, nicotine dependence, and withdrawal symptoms. Primary outcome is continuous abstinence at 6 months. Sample size: For an estimated difference of quit rates of 15% at 24 weeks (30% for group A vs. 15% for group B) 121 subjects per group are needed (Total = 242 subjects). Statistical analysis: T tests (rational variables) and x2 test or Fisher's exact test (nominal variables) will be used as appropriate. Expected benefits: This study might contribute to optimize the current use of varenicline.
The purpose of this study is to develop and test a series of culturally relevant and appropriate booklets in Spanish, designed to assist Hispanic smokers in quitting smoking and remaining smoke-free.
Specific Aim: To conduct a randomized controlled trial among permanent employees of Partners HealthCare, Inc., and their adult dependents, who are current tobacco smokers. The trial will compare two interventions designed to help smokers stop using tobacco: (1) External Coaching Program (Standard Care) and (2) Internal Coaching Program, a chronic disease management strategy for treating tobacco use and dependence.
This study is comprised of 2 phases to study the impact of a text message system on overall adherence to a web-based smoking cessation program. Phase I uses a full factorial design to identify the most optimal text message intervention to maximize adherence to the BecomeAnEX.org smoking cessation program. Phase II is a randomized controlled trial that compares regular BecomeAnEX users to those who will receive the optimized text message intervention (from Phase I) in conjunction with BecomeAnEX for impact on long-term abstinence.
The study evaluates the effectiveness of an internet-based smoking cessation program for Korean Americans.
Relapse after a serious quit attempt occurs in 70-90% of smokers who try to quit smoking. This study utilizes a sequential, multiple assignment, randomized trial (SMART) design - - an innovative multi-phase approach - - to test post-relapse treatments designed to assist smokers to make a new, successful quit attempt. This study will test Relapse Recovery (RR) treatments that are applied at two stages following relapse: 1) RR Preparation Phase treatments for smokers who relapse after an initial quit attempt, and 2) RR Cessation Phase treatments for relapsed smokers who decide to make a new quit attempt. Smokers motivated to quit smoking will make an initial quit attempt in the Quit Phase (cessation medication + counseling). Participants who relapse will be randomized to one of three RR Preparation Phase treatments (Behavioral [Smoking] Reduction Counseling + the Nicotine Mini-Lozenge; Recycling Counseling that encourages participants to quit again as soon as possible; and Preparation Phase Control). RR Preparation Phase participants (other than controls) who elect to try a new quit attempt will be randomized to one of four RR Cessation Phase treatments based on a 2X2 fully-crossed factorial design testing two factors: Supportive Counseling (vs. Brief Information) and Skill Training (vs. Brief Information). All RR Cessation Phase participants will receive 8 weeks of combination nicotine replacement therapy (nicotine patch + nicotine mini-lozenge). The investigators hypothesize that RR Preparation Phase Reduction treatment will significantly increase long-term abstinence rates relative to the Preparation Phase Control condition.
The purpose of this study is to evaluate a smoking cessation program for employees at the Yale University dining hall. Two pilot dining halls and six paired dining halls (3 test and 3 control sites) will be offered a contingency management/pharmacotherapy smoking cessation intervention at the work site.
A single arm pilot study conducted to assess the feasibility of having Manitoba Pharmacists provide support (product and cognitive) to low-income (receiving social assistance) smokers wishing to quit smoking.
This study will test the efficacy of a cessation intervention for caregivers in a large, inner-city Pediatric Emergency Department. The investigators will randomize 750 caregivers who smoke who present to our Pediatric Emergency Department with their child who has a Second Hand Smoke exposure-related illness to either one of two conditions: 1) Screening, Brief Intervention, and Assisted Referral to Treatment (SBIRT); or 2) Healthy Habits Control (HHC). The Screening, Brief Intervention, and Assisted Referral to Treatment condition will include a brief form of the Clinical Practice Guideline: Treating Tobacco Use and Dependence, motivational interviewing, engaging and personalized materials on the effects of smoking and Second Hand Smoke exposure, immediate access to caregivers' choice of cessation resources (e.g., Quitline, smokefree.gov, or txt2quit), a 12-week supply of nicotine replacement therapy and weekly booster materials for 12 weeks. The Healthy Habits Control program will be used as an attention control in which caregivers will receive instruction on healthy lifestyle choices to improve the child's health.
