Active clinical trials for "Tobacco Use Disorder"

Male and female smokers were recruited to undergo 2 phases of smoking cessation. Each phase was 4 days long and involved 3 brain-imaging scans, blood draws and an intervention involving progesterone or a matched placebo.

The Sponsor is doing a research study to assess the effects of a smartphone program designed to help users smoke less and eventually quit. When participants join, their involvement in the core study will last 8 weeks. After 8 weeks, they will have the option to continue using the program to guide their quit journey or participate in follow-up research.

The purpose of this study is to assess the efficacy and safety of a novel nicotine product for continuous abstinence from smoking. Efficacy of product will be evaluated by assessments of self-reported abstinence, verified by exhaled carbon monoxide (CO) levels.

The overall purpose of this research is two-fold. First, the two smoking cessation medication treatments with the strongest evidence of effectiveness have never been directly compared. This research will determine how these two treatments compare in effectiveness in a head-to-head trial, and which types of smokers benefit most from each. Second, much of the data on smoking and health come from studies from many years ago. Today's smokers differ from earlier smokers in many ways that could influence the impact of smoking on health (e.g., weight, sex, diet, socio-economic status); the proposed work will determine how smoking cessation affects cardiovascular and pulmonary health in today's smokers.

Long-term NRT has not been studied in patients with COPD, and smokers in the United States with COPD are still asked to choose between immediate quitting or continued smoking. The purpose of this study is to see if guided maintenance therapy (GMT), using long-term NRT, might prove to be a reasonable alternative to the standard approach of asking patients to quit immediately. The investigators believe that GMT with long-term NRT will reduce overall exposure to cigarette smoke, reduce harm related to smoking, and ultimately lead to greater quit rates. In this study, 398 smokers with COPD will be randomly assigned to either receive: 1) traditional smoking cessation (SC) or 2) long-term, guided maintenance therapy with NRT (GMT). The SC intervention will be based on a standard approach to smoking cessation, including smoking cessation counseling supplemented with combination NRT (a nicotine patch plus the patient's choice of gum or lozenge) if they are willing to make a quit attempt. The GMT intervention will consist of counseling, focused on medication adherence and smoking reduction, plus 52 weeks of combination NRT. After 3, 6 and 12 months of treatment, we will compare the two treatments based on their effects on smoking cessation, number of cigarettes smoked, exposure to carbon monoxide and smoking-related carcinogens, COPD symptoms, breathing function, and smoking-related hospitalizations or death. The investigators will also analyze the data in such a way that will be able to identify which patients are most likely to benefit from treatment. This analysis will allow patients to estimate their chances of success based on their own personal characteristics and which treatment they choose. The investigators study addresses research priorities identified in recent smoking cessation guidelines and builds upon the input of our Patient Advisory Panel and our Stakeholder Advisory Committee. This study reflects the interests expressed by smokers in prior surveys and addresses the limited reach and effectiveness of traditional approaches to smoking cessation. If our GMT approach is effective, our study could change the recommendations provided in clinical practice guidelines and change the way that insurance companies pay for smoking cessation treatment. GMT could provide an alternative for millions of smokers with COPD who are not currently benefiting from traditional approaches to smoking cessation

This is a clinical trial to determine if the nicotine inhaler in combination with counseling will help pregnant women quit smoking, and whether it is safe when compared to placebo (an inactive inhaler).

Cigarette smoking is the leading preventable cause of death in the U.S. The 2008 US Public Health Service Smoking Cessation Guideline recommends offering effective treatment to smokers in all health care settings, including hospitals. Nearly 4 million smokers are hospitalized each year, and hospital admission offers a "teachable moment" for intervention. Hospital-initiated smoking cessation intervention is effective, but only if contact continues for more than 1 month after discharge. The challenge is to translate this research into clinical practice by identifying an evidence-based cost-effective model that U.S. hospitals can adopt. The major barrier is sustaining contact after discharge. This project tests an innovative strategy to streamline the delivery and maximize the uptake of post-discharge smoking interventions. Specific Aim: To test the effectiveness of an innovative strategy to maximize smokers' use of evidence-based tobacco treatment (counseling and medication) after hospital discharge, thereby increasing the proportion of smokers who achieve long-term (6-month) tobacco abstinence. Study Design: A multi-site randomized controlled comparative effectiveness trial will enroll 1350 adult smokers admitted to 3 acute care hospitals in Massachusetts and Pennsylvania. All subjects will receive a brief in-hospital smoking intervention and be randomly assigned at discharge to either Standard Care (passive referral to their state quitline) or Extended Care, a 3-month program consisting of (1) Free Medication: A 30-day supply of FDA-approved medication (nicotine replacement, bupropion, or varenicline) given at hospital discharge and refillable for a total of 90 days to encourage medication use and adherence; (2) Interactive Voice Response (IVR) Triage to Telephone Counseling from a national quitline provider. IVR aims to encourage medication adherence and enhance counseling efficiency by identifying smokers who need post-discharge support. Immediate transfer of a patient from automated IVR call to live telephone counselor will facilitate a successful connection to counseling. Outcomes, assessed at 1, 3, and 6 months after hospital discharge, are: (1) intervention effectiveness (cotinine-validated 7-day point-prevalence tobacco abstinence rate at 6 month follow-up [primary outcome] and other tobacco abstinence measures); (2) treatment utilization, and (3) cost-effectiveness (cost per quit). Exploratory analyses will examine the intervention's effect on hospital readmissions and mortality in the 6 months after discharge.

The proposed study will measure the change of cortical excitability during nicotine craving and examine the effects of Repetitive Transcranial Magnetic Stimulation (rTMS) on nicotine craving and cue-reactivity among adult regular smokers.

This randomized clinical trial among SMI smokers assessed whether the EDSS with carbon monoxide monitor and health-checklist feedback lead to higher rates of initiation of smoking cessation treatment, days of smoking abstinence and Fagerstrom Dependence scores, compared to use of the EDSS with checklist feedback alone.

Many smokers fail to take their smoking cessation medication as recommended. This research is designed to identify treatments that improve the use of cessation medications and to determine whether an increase in medication use results in increased cessation success. This research will also identify treatments that help people stay quit after a quit attempt and will pioneer more efficient research methods.
