Active clinical trials for "Tobacco Use Disorder"

Smoking is the leading cause of morbidity and mortality in the U.S. Interventions that increase successful quit attempts among depressed smokers with chronic medical illnesses are particularly important for the VA healthcare system because rates of tobacco use, depression, and chronic medical illnesses are significantly higher among Veterans compared to the general population. Providing smoking cessation services augmented with mood management to Veterans via telephone may increase access to, and utilization of, evidence-based smoking cessation counseling and decrease rates of smoking-related complications for Veterans with chronic medical illnesses and depression. Yet, the reach of smoking cessation telephone counseling has been limited among populations with mental illness. The investigators intend to combine the potency of co-delivered mood management and reach of telephone-delivered interventions by testing the telephone delivery of behavioral mood-management for smoking cessation among smokers with depression and chronic medical illness.

This is a pilot human experimental study to evaluate whether the use of an e-cigarette affects lung function, exhaled CO levels, and quantitative tobacco cigarette consumption in active tobacco smokers. Subjects recruited from the Winchester Chest Clinic (WCC), Adult Primary Care Clinic (PCC) and the Smilow Cancer Hospital Smoking Cessation Service will be randomized to 1 of 2 groups: (1) nicotine patch and intensive counseling (standard care) plus nicotine e-cigarette; (2) nicotine patch and intensive counseling plus non-nicotine e-cigarette.

This study will evaluate behavioral and psychological appeal, toxicity, and effect of e-cigarettes on smoking behavior and nicotine addiction in chronic smokers with serious mental illness (SMI) who have failed to quit smoking. A total of 240 participants will be enrolled and randomly assigned to either receive a supply of e-cigarettes for 8 weeks plus assessments (baseline & weeks 2, 4, 6, 8, 13, & 26) or assessments only. This single-blinded study will provide e-cigarettes and instructions on their safe use. Level of appeal will be inferred from carefully assessed use of e-cigarettes and reduction in combustible tobacco. Qualitative data will also be collected from participants assigned to e-cigarettes, given that unanticipated issues will almost certainly arise in connection with e-cigarette use that can only be captured within a qualitative debriefing at the conclusion of participants' time in the study.

This study will test feasibility, in smokers with lung, head & neck, and bladder cancers, that examines the effect of e-cigarette substitution, on measures of smoking-related toxicity and medical outcomes. The aim of the study is to determine the appeal of e-cigarettes compared to regular combustible cigarettes.

This randomized pilot clinical trial studies the effects of electronic cigarettes on the lungs. Studying the effects of electronic cigarettes on the lungs may provide the Food and Drug Administration (FDA) and other government regulators with important information, which may help in developing future regulations to make electronic cigarettes safer.

Three hundred-twenty (320) adult smokers of menthol or non-menthol combustible cigarettes will be recruited and randomly assigned to one of five groups (n=64/group), who will be asked to switch for 12 weeks to ad libitum use of combustible cigarettes (matched to subjects' menthol preference) containing either 0.4, 1.4, 2.5, 5.6 or 16.9 mg nicotine (standardized nicotine yields ranging from 0.02-0.80 mg/cigarette), respectively. Each group will include 32 heavy (≥ 20 cigarettes/day), and 32 light smokers (≤10 cigarettes/day), who are hypothesized to be more sensitive to nicotine's reinforcing effects. Participants will also have free access to nicotine-containing e-cigarettes (JUUL) throughout the 12-week period. Abuse liability of combustible cigarettes will be assessed by behavioral (cigarettes/day, time to first cigarettes), self-report (rewarding effects, withdrawal symptoms) and biochemical indices (expired air carbon monoxide, cotinine blood sampling). In laboratory sessions, we will measure nicotine thresholds for detecting and recognizing the addictive, rewarding effects of smoking. This study is designed to help the FDA identify a target nicotine threshold that will not attract young people to smoking or induce relapse in former smokers. Additionally, we will determine the level of cigarette nicotine reduction that will be tolerated without inducing dissatisfaction in smokers, information that is relevant to the FDA for designing a stepwise nicotine reduction policy that can be implemented without widespread objections. The knowledge gained from this project will greatly increase our knowledge of nicotine addiction and will help frame an FDA policy relating to the regulation of the nicotine content of tobacco. Ultimately, a well-designed nicotine reduction policy has the potential to greatly reduce the enormous toll of death and disease caused by cigarette smoking.

Background: Women Veterans are the fastest growing segment of Veterans Health Administration (VHA) users. This dramatic growth has created challenges for VHA. Gender disparities persist in cardiovascular (CV) and diabetes risk factor control, and rates of depression, anxiety, and mental health comorbidity are disproportionately high among women Veterans. Furthermore, a high rate of women Veterans' attrition from VA care, along with organizational barriers to care, substantiate that organizational changes are needed in order to engage and retain women Veteran VHA users in evidence-based, patient-centered care. Objectives: The Enhancing Mental and Physical health of Women through Engagement and Retention (EMPOWER) QUERI addresses VHA Blueprint for Excellence Strategy 6, by advancing "personalized, proactive, patient-centered" care models, and Transformational Strategy 7.2.g by implementation of innovative care models in women Veterans' health care." The EMPOWER QUERI Program is designed to improve women Veterans' engagement and retention in evidence-based care for three high priority health conditions, i.e., prediabetes, cardiovascular, and mental health. To achieve this impact goal, we propose a cohesive portfolio of projects with the following aims: (1) To use an evidence-based implementation strategy that emphasizes local tailoring of care models, multilevel stakeholder engagement, and systematic evaluation of complex implementation processes in order to enrich organizational capacity for innovations in women Veterans' VHA health care; (2) To implement personalized, proactive, patient-centered innovations in VHA women's health that are acceptable, feasible, satisfactory, relevant, and effective for both providers and patients, thereby encouraging women Veterans' engagement and retention and sustainability of the innovations; and, (3) To generate implementation "playbooks" for our partners that are scalable and serve as guidance for future implementation of a broader array of evidence-based women's health programs and policy. Methods: Three projects will be conducted by an experienced multidisciplinary team. "Tailoring VA's Diabetes Prevention Program to Women Veterans' Needs" is a one-year QI project to be conducted in VA Greater Los Angeles women's health clinics. Women Veterans with prediabetes will select an in-person, peer-led or online gender-specific, evidence-based diabetes prevention program to address their risk behaviors and health conditions. "Facilitating Cardiovascular Risk Screening and Risk Reduction in Women Veterans" will increase identification of CV risk among women Veterans, enhance patient/provider communication and shared decision-making about CV risk, and provide a supportive, coordinated health coaching intervention to facilitate women Veterans' engagement and retention in appropriate health services. "Implementation of Tailored Collaborative Care for Women Veterans" will evaluate implementation of an evidence-based collaborative care model tailored to enhance provider- and system-level capabilities to address women Veterans' anxiety and depression treatment needs, thereby improving organizational primary care-mental health integration (PC-MHI) effectiveness and women Veterans' engagement and retention in PC-MHI. Both implementation research studies will use a modified stepped wedge design and will apply the evidence-based Replicating Effective Programs (REP) implementation strategy. Mixed methods implementation evaluations will focus on investigating primary implementation outcomes of adoption, acceptability, feasibility, and reach. Multilevel stakeholder engagement will be prioritized. Program-wide organizational-, provider-, and patient-level measures and tools will be utilized to enhance synergy, productivity, and impact. As a coherent program of women's health implementation research and quality improvement, the proposed EMPOWER QUERI will constitute a major milestone in achieving BPE strategies and realizing women Veterans' engagement and, ultimately, empowerment in our VHA system.

The purpose of this project is to build capacity for quality improvement (QI) in small primary care practices across Washington, Oregon and Idaho by improving risk factors for heart attacks such as blood pressure, cholesterol and smoking. The Northwest Coalition for Primary Care Practice Support will assist practices by providing them with a QI coach, creating group learning opportunities, and conducting educational outreach activities. An innovative study design will be used to determine what levels and types of support are most helpful and effective.

A Randomized, Open-Label, Cross-Over Study to Assess Nicotine Uptake and Subjective Measures with Use of JUUL 5% Electronic Nicotine Delivery Systems (ENDS) Compared to Usual Brand Combustible Cigarettes, a Comparator E-Cigarette, and Nicotine Gum in Healthy Adult Smokers

Adolescents are an important vulnerable population to consider as the FDA moves toward a nicotine reduction policy. Such a policy, which would mandate a reduction of nicotine in all commercially available cigarettes, has the potential to transform public health and greatly reduce the toll of tobacco-related death and disease. Yet, data on the effects of such a policy on cigarette use among adolescents are lacking. Further, the advent of e-cigarettes and the popularity of alternative tobacco products have fundamentally altered the current landscape of nicotine delivery, and these products are widely used by adolescents. Although adolescent cigarette use is at an all-time low in the U.S., this reduction has been mirrored by an increase in e-cigarette use, and multiple tobacco product (MTP) use is the most common pattern of use in youth. Adolescent MTP users are more likely to be dependent on nicotine and to have begun using tobacco earlier than their single-product using peers. Thus, MTP-using youth differ from youth who solely smoke cigarettes in meaningful ways that have implications for responses to a nicotine reduction regulatory policy. In adults, longer-term studies have demonstrated that very low nicotine content (VLNC) cigarette exposure results in fewer cigarettes smoked and reduced toxicant exposure; however, increased use of alternative tobacco products has also been reported. No studies to date have examined the effects of VLNC cigarettes on MTP use or toxicant exposure in youth. This study will use real-time, smartphone-based ecological momentary assessment (EMA) and laboratory-based assessments to: (1) investigate the effects of cigarette nicotine reduction on cigarette and MTP use, (2) assess the influence of cigarette nicotine reduction on the harms associated with tobacco use, including nicotine and toxicant exposure, respiratory symptoms, perceived health risk and nicotine dependence, and (3) use a combination of laboratory and real-time assessment to investigate the effects of nicotine reduction on changes in withdrawal, craving, and the reinforcing efficacy of cigarettes to characterize the mechanisms by which VLNC use may affect behavior. Overall, this project will help determine the effects of VLNC cigarettes on real-world tobacco use behavior and indices of tobacco-related harm in adolescents, and examining the mechanisms through which nicotine reduction in cigarettes may effect such changes.
