NCT ID: NCT02602288 Completed - Nicotine Dependence Clinical Trials

Babies Living Safe and Smokefree

BLiSS
Start date: February 2016
Phase: N/A
Study type: Interventional

The purpose of this randomized controlled trial is to develop and test the efficacy of a multilevel, multimodal intervention designed to modify maternal smoking behavior to reduce children's exposure to secondhand tobacco smoke (primary outcome) and promote their smoking cessation (secondary outcome). Low-income mothers who smoke will be enrolled. Mothers will be recruited from the supplemental nutrition program, Women, Infants and Children (WIC) clinics. All mothers visiting WIC clinics will receive a clinic-level intervention, which consists of nutrition counselors following an "ask, advise, and refer" protocol to identify if their children are exposed to secondhand tobacco smoke, advise mothers who smoke about the harms of such exposure and the benefits of reducing exposure, and referring mothers to the trial. Screened eligible mothers will be consented and randomized to an attention control condition focused on nutrition (CTL) or to an experimental (EXP) multimodal behavioral intervention that integrates telebased counseling to promote the reduction of child secondhand smoke exposure (SHSE) and maternal smoking with an adjunct smoking cessation mobile app and nicotine replacement therapy use. The investigators will test the primary hypothesis that relative to children in the CTL condition, those in the EXP condition will have lower exposure SHSE as measured by mothers' reports and child cotinine levels. The investigators will also test the secondary hypothesis that relative to mothers in the CTL condition, those in the EXP condition will have higher bioverified 7-day point prevalence quit rates. In addition, the study will: (a) evaluate if specific psychosocial and behavioral factors-- social support, urge coping skills, self-efficacy, and SHSe protective behaviors--mediate the effects of the EXP intervention on outcomes and (b) explore whether other residential smokers, level of nicotine dependence, depressive/anxious symptoms, weight concerns, intervention dosage, and pregnancy status predict outcomes and moderate treatment effects.

NCT ID: NCT02601599 Completed - Smoking Clinical Trials

Medical Student INtervention to Promote Effective Nicotine Dependence and Tobacco HEalthcare

MIND-THE-GAP
Start date: November 2015
Phase: N/A
Study type: Interventional

Background: Smoking counselling during hospitalisation with post-discharge follow-up increases quitting. However, provision of cessation care for hospitalised patients is suboptimal. Students are potentially an untapped resource for providing cessation advice, but no studies have investigated this. Aim: To determine if medical students can encourage motivation to stop smoking (MTSS; primary outcome) in hospitalised smokers . Design: 2-arm RCT Setting: RCSI (www.rcsi.ie) and Connolly Hospital (www.hse.ie/eng/services/list/3/hospitals/Connolly/). Participants: Inpatient smokers. Intervention and procedures: 60 graduate medical students will receive standardised motivational interviewing training in the provision of cessation advice. Each student will be randomly assigned to counsel ~1-3 smokers each, including an individual in-hospital, face-to-face session and post-discharge phone counselling. Training and implementation will cover Sept-2015-May-2016. Smokers will be randomised to 'usual care' (n~90), or intervention (n~90, student-delivered motivational interviewing). A researcher will enable recruitment and follow-up, and conduct a qualitative evaluation of programme participants.

NCT ID: NCT02601521 Completed - Smoking Cessation Clinical Trials

Comparative Effectiveness of Two Tobacco Cessation Interventions for Employees of Partners HealthCare, Inc.

PiHQ
Start date: November 2015
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02599571 Terminated - ADHD Clinical Trials

Effects of Nicotine Reduction on Smoking Behavior in ADHD Smokers

ADHDenic
Start date: March 30, 2016
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate the impact of different nicotine levels in cigarettes with individuals who have ADHD.

NCT ID: NCT02596685 Completed - Clinical trials for Tobacco Use Disorder

Effects of Electronic Cigarette Use on the Lungs

Start date: December 8, 2015
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02595749 Completed - Nicotine Dependence Clinical Trials

Effects of Intranasal Oxytocin on Cigarette Smoking

Start date: July 2016
Phase: Phase 4
Study type: Interventional

Socioemotional processing dysfunctions (i.e., disruptions in affective, cognitive, and neural processes that encode, interpret, and respond to socially and emotionally relevant stimuli) have been implicated in tobacco smoking and relapse, however this potential target for medication development has not been systematically examined. Evidence from animal and human laboratories indicate that administration of intranasal oxytocin enhances socioemotional processing and may be efficacious for the treatment of drug addiction, including nicotine dependence. In order to evaluate the potential efficacy of intranasal oxytocin for smoking cessation, this laboratory-based proposal will examine whether intranasal oxytocin attenuates smoking lapse, nicotine withdrawal, and socioemotional processing disruptions in regular smokers following overnight abstinence.

NCT ID: NCT02592772 Completed - Nicotine Dependence Clinical Trials

Manipulating Tobacco Constituents in Male Menthol Smokers

Start date: February 4, 2016
Phase: N/A
Study type: Interventional

This study examines the potential effect of reducing nicotine content or menthol or both in men. It will also examine whether there are gender differences in manipulating tobacco flavors and nicotine concentrations in cigarettes on smoking behavior.

NCT ID: NCT02590393 Completed - Nicotine Dependence Clinical Trials

The Role of Nicotine and Non-Nicotine Alkaloids in E-Cigarette Use and Dependence

Ecig1
Start date: May 21, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

The advent of electronic cigarette (e-cigarette) technologies represents one of the most significant developments in the last several decades, and provides a novel and promising strategy for substantially reducing the morbidity and mortality associated with smoking. However, serious concerns have been raised regarding the possibility that e-cigarettes will sustain a dependency on nicotine and that they may lead to continued use of conventional cigarettes known to be extremely harmful to health. Cigarette addiction critically involves a dependence on nicotine, but it is likely that other tobacco constituents contribute to dependence as well. Recent evidence suggests that non-nicotine tobacco alkaloids, or NNTAs (including anabasine, anatabine, nornicotine, and myosmine) may play a role in tobacco dependence. These alkaloids have been shown to augment the reinforcing effects of nicotine in animal models and to affect cravings in human smokers. E-cigarettes contain variable quantities of nicotine and NNTAs, but there is virtually no information available concerning the role of e-cigarette nicotine or NNTA content in influencing the concurrent use of cigarettes and e-cigarettes, when smokers attempt to switch from conventional combustible cigarettes to e-cigarettes. Additionally, it is not known whether the presence of nicotine and NNTAs in e- cigarettes may sustain dependence, making it difficult to relinquish these products. The proposed project will assess the acceptability, extent of switching behavior, and degree of dependence maintained when smokers are provided with e-cigarettes containing nicotine and NNTAs.

NCT ID: NCT02587312 Completed - Nicotine Dependence Clinical Trials

Evaluation of Very Low Nicotine Content Cigarettes in Adolescent Smokers

Start date: October 13, 2016
Phase: N/A
Study type: Interventional

The purpose of this study is to determine how reducing the level of nicotine in cigarettes may affect adolescent smoking behavior. In this study, the researchers will randomize adolescent (age 15-19) daily smokers to either receive VLNC cigarettes or normal-nicotine content (NNC) study cigarettes for three weeks following a one-week usual-brand baseline period. Participants will be instructed to smoke only those cigarettes. The researchers will conduct daily assessments of total cigarette use (both study cigarette and non-compliant use of usual brand cigarettes), craving, and withdrawal, weekly assessments of breath carbon monoxide (CO) levels, cigarette acceptability, risk perceptions of VLNC and NNC cigarettes and demand for usual-brand cigarettes, and pre- vs. post-use measures of nicotine and toxicant exposure. Overall, the project will help determine how VLNC cigarettes may affect real-world smoking behavior in adolescents, and illuminate the potential mechanisms through which these products may effect such changes. Such knowledge will contribute to the science base that may inform future policy decisions.

NCT ID: NCT02576899 Completed - Clinical trials for Posttraumatic Stress Disorder

Improving Functional Outcomes of Veterans With PTSD and Tobacco Dependence

ACT-PT
Start date: September 1, 2015
Phase: Phase 1
Study type: Interventional

Veterans with PTSD have high rates of smoking (34%-86% vs. 18% in the general population) and have substantial difficulties with quitting tobacco. Despite the significant morbidity and mortality associated with smoking, no smoking cessation treatments exist that intensively target PTSD symptoms as an obstacle to quit smoking, although this is a significant barrier to quitting for many Veterans. In addition, no smoking cessation treatments have a large emphasis on improving the functioning of Veterans with PTSD and tobacco dependence, although both PTSD and tobacco use negatively affect functioning across physical, mental health, and social domains. The goal of this SPiRE project is to evaluate Acceptance and Commitment Therapy for Veterans with PTSD and Tobacco Use (ACT-PT), which is an acceptance and mindfulness-based smoking cessation treatment for Veterans with PTSD and tobacco dependence. ACT-PT specifically targets smoking cravings related to PTSD symptoms and memories of trauma, in addition to difficulties managing PTSD symptoms. negative affect and nicotine withdrawal symptoms during quit attempts. ACT-PT includes structured intervention components that guide Veterans to replace smoking as a coping strategy for PTSD symptoms and memories with alternative coping strategies (e.g., mindfulness, acceptance). And healthy living activities (e.g., engaging in work, expanding social networks, engaging in physical exercise) that are consistent with Veterans' values. This project involves a small randomized clinical trial study of Veteran smokers with PTSD and tobacco dependence randomized to one of two different types of psychosocial treatment: ACT-PT versus the American Lung Association's Freedom From Smoking Program [FFS]. This study has two primary aims: 1) evaluate the relative feasibility and acceptability of the two interventions (including ease of recruitment, randomization proportion, staff and Veteran acceptance of the treatment, retention rates, treatment adherence, fidelity, ease of the assessment process), and 2) evaluate the preliminary efficacy of ACT-PT vs. FFS with the primary outcomes of tobacco use, PTSD symptoms, health-related quality of life, and functional impairment.
