Smoking Cessation Clinical Trials

The purpose of this research study is to evaluate an electronic visit (e-visit) for smoking cessation. Participants will be randomly assigned to receive either the smoking cessation e-visit or not. The e-visit will look similar to an online questionnaire asking about smoking history, motivation to quit, and preferences for medications for quitting smoking. Participants may receive a prescription for a smoking cessation medication as an outcome of the e-visit, if randomized to the e-visit group, but there is no requirement to take any medication. This study consists of questionnaires and breath samples provided at 4 separate time points throughout the study. Participation in this study will take about 24 weeks. Read Less

The purpose of this study is to determine if exenatide improves end-of-treatment smoking abstinence rates and to determine if exenatide mitigates post-cessation weight gain. Read Less

This study will look at the effectiveness of a new treatment protocol for anxious and depressed smokers. Participants with clinically significant anxiety or depression will receive either the standard smoking cessation treatment or the Unified Protocol for Smoking Cessation Treatment. This study will demonstrate that a single treatment protocol can effectively address both smoking and the complex emotional comorbidities that are widespread in smokers will provide a novel, impactful, and highly disseminable treatment option missing from today's smoking cessation arsenal.

The investigators are proposing to examine new strategies for helping patients hospitalized for an acute coronary event adhere to recommendations to quit smoking. The investigators are interested to see whether offering financial incentives for smoking cessation, combined with medications to ameliorate withdrawal, can significantly reduce smoking in a population for which continued smoking has disproportionately negative health effects. The proposed trial can provide significant knowledge for promoting adherence to smoking cessation guidelines in patients with cardiac disease Read Less

Smokers living with HIV represent a major health disparity population in the United States and the world more generally. Major contributing factors to the maintenance and relapse of smoking among smokers living with HIV include increased exposure to multiple stressors associated with HIV, which often exacerbates anxiety/depression. In a previous project, the feasibility, acceptability, and initial efficacy of a 9-session, cognitive-behavioral-based intervention to address smoking cessation by reducing anxiety and depression via specific emotional vulnerabilities (anxiety sensitivity, distress tolerance, and anhedonia) was tested against an enhanced standard of care in a pilot randomized controlled trial (NCT01393301). It was found that when compared to a brief enhanced treatment as usual control, patients in the intervention achieved higher short-term and long-term smoking abstinence rates. In this project, the investigators seek to test this same intervention in a fully powered, 3-arm efficacy/effectiveness trial. The goal of this study is to randomize 180 smokers across three sites to test the efficacy/effectiveness of the intervention at increasing point prevalence abstinence by reducing anxiety and depression at a 1-month follow-up (the end of treatment timepoint/ approximately 1-month post quit day) and a 6-month follow-up (approximately 6-months post quit day).

Smoking cigarettes remains the number one preventable cause of death and disease in the US. Smokers who call tobacco quitlines and use marijuana struggle to quit tobacco due to the interactive effects of nicotine and marijuana. A recent study found that 25% of callers to state quitlines said they were using marijuana and 44% of those were interested in quitting or cutting back their marijuana use (in addition to wanting to quit smoking). The investigators propose to develop an integrated intervention for co-users of marijuana and tobacco to be delivered via state-funded quitlines. The investigators will incorporate key elements of an evidence-based brief behavioral intervention called 'The Marijuana Check-Up' into the tobacco quitline treatment. The investigators will evaluate the feasibility, acceptability and preliminary effects of the new intervention in a small randomized pilot study with 100 co-users recruited from four participating state quitlines. Outcomes measured at 3 months post randomization will include tobacco abstinence (biochemically verified) and days used marijuana. The investigators hypothesize that the intervention will: (1) be feasible to deliver (measured by coach treatment fidelity scores); (2) be acceptable to co-users (measured by enrollments into the study and call completion numbers); (3) increase tobacco cessation rates compared with standard quitline treatment; (4) increase co-users motivation to change MJ use; and (5) produce greater reduction in days using MJ compared with standard quitline treatment. The proposed brief behavioral intervention addressing co-use may increase quitline callers' chances of achieving and maintaining tobacco abstinence and increase participants' motivation to reduce marijuana use. As non-medicinal marijuana use becomes common and legal in more states, a low touch phone and web-based intervention for co-users of marijuana and tobacco could improve health outcomes for many. Findings will inform development of scalable public health intervention strategies for co-users easily implemented across quitlines. Read Less

This open-label study will evaluate EMB-001, comprised of metyrapone, a cortisol synthesis inhibitor marketed as a diagnostic drug for testing hypothalamic-pituitary-adrenal (HPA) axis function, combined with oxazepam, an anxiolytic and sedative/hypnotic benzodiazepine, to help smokers abstain from smoking during a 12-week trial period.
