260 Clinical Trials for Various Conditions
The proposed study will help fill gaps in existing research by determining if nicotine-dependent cigarette smokers show changes in α7 nicotinic acetylcholine receptor (nAChR) availability when compared to matched historical controls using positron emission tomography (PET) imaging and the radioactive ligand \[18F\]-ASEM (3-(1,4-diazabicyclo\[3.2.2\]nonan-4-yl)-6 \[18F\]fluorodibenzo\[b,d\]thiophene 5,5-dioxide), an α7 nAChR antagonist. The study will also explore whether α7 nAChR availability influences clinically relevant measures of tobacco abstinence (e.g., withdrawal and craving, cognitive impairment), self-reported cigarettes per day, and time to relapse during an 8-day quit attempt during which smokers can receive escalating payments contingent upon providing objective evidence (breath CO and urinary cotinine) of smoking abstinence.
This study will examine mechanisms linking Obsessive-Compulsive Disorder symptomatology to tobacco dependence.
The goal is to examine sex differences in amphetamine-induced dopamine release in tobacco smokers and nonsmokers.
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. Celecoxib may be effective in preventing lung cancer in tobacco smokers. PURPOSE: Phase II trial to study the effectiveness of celecoxib in preventing non-small cell lung cancer in tobacco smokers.
The purpose of this pilot study is to evaluate allergen-induced nasal airway inflammation following nasal application of Dermatophagoides farinae (Der f), or house dust mite, extract in e-cigarette users, cigarette smokers, and non-smokers.
This phase II trial tests whether broccoli seed and sprout extract works to break down cancer causing substances of tobacco in heavy smokers. Smokers are at increased risk for developing lung, head and neck, and other cancers. Broccoli seed and sprout extract may help break down and remove toxic substances caused by tobacco use and possibly produce substances that may protect cells from tobacco smoke-induced damage in current smokers.
The purpose of this clinical study is to evaluate changes in biomarkers of exposure (BOE) to tobacco smoke constituents after smokers switch from combustible cigarettes to use of one of the three electronic cigarettes or abstinence.
Craving for cigarettes is an important aspect that leads to challenges with smoking cessation. Persons with schizophrenia are more likely to smoke and to be heavier smokers than persons without schizophrenia, and may experience craving differently as well. Minocycline is an antibiotic medication that may impact craving. We will conduct a two-week randomized, double-blind, placebo-controlled, parallel group pilot study to investigate the effects of minocycline vs. placebo on craving and smoking behaviors in smokers with schizophrenia. Participants will take minocycline or matching placebo for two weeks. Participants will be assessed on aspects of craving and smoking behavior at baseline and after 1 and 2 weeks of minocycline or placebo treatment.
The goal of this clinical trial is to compare the reach and effectiveness of the Refer2Quit intervention for increasing tobacco use treatment and quit rates among household members who smoke versus a treatment as usual group. This clinical trial also aims to study household member and pediatric patient characteristics that are associated with reach and effectiveness of Refer2Quit.
This study will evaluate the efficacy and economic impact of a theoretically-based, fully automated, interactive smartphone-based smoking cessation intervention.
The purpose of this study is to evaluate changes in exposure to selected harmful and potentially harmful constituents (HPHC) by measuring biomarkers in adult smokers who partially or completely switch from smoking cigarettes to oral tobacco-derived nicotine (OTDN) products compared to those who continue exclusive smoking cigarettes or stop using all tobacco products.
Health care systems are key channels for delivering tobacco cessation treatment to the smokers in a population. A population-based approach could complement office-based care and offload busy clinicians. The project will conduct population-based proactive outreach to current smokers in a health care system's primary care practices and randomize smokers who respond to the outreach to 3 groups: 2 alternative evidence-based cessation resources or to usual care. Specific Aims: Aim 1: To determine the feasibility and reach of the program Aim 2a: To determine whether the 2 intervention arms combined increase the proportion of smokers who use tobacco cessation treatment over a 6-month follow-up compared to those randomized to usual clinical care. Aim 2b: To determine whether each of the two intervention arms increases the proportion of smokers who use tobacco cessation treatment over a 6-month follow-up, compared to those receiving usual clinical care.
This randomized pilot clinical trial studies nicotine delivery from novel non-tobacco electronic system (ENDS) in smokers. Studying the levels of nicotine delivered by various types and brands of ENDS to the bloodstream, and comparing this to the levels delivered from conventional cigarettes (the participant's own brand) may help provide information about the use of nicotine-containing products that may help inform/reform current tobacco policy, practice, and harm reduction approaches.
The long-term goal of this program of research is to disseminate an effective, brief computer-based intervention that can be readily integrated into HIV treatment settings to motivate tobacco quitline use among smokers living with HIV. The overall objective of this application is to develop this computer intervention, modify it based on initial piloting and feedback, and obtain preliminary data supporting the efficacy of the intervention. This will be accomplished by pursuing three specific aims: 1) to develop and conduct preliminary pilot testing (n=16) of a brief, computer-based intervention intended to motivate tobacco quitline use among cigarette smokers living with HIV (Computer Intervention to Motivate Engagement in Tobacco Quitline treatment; CI-METQ) and to develop and pilot (n=4) a computer-based, time matched nutrition education for PLWH control intervention (NC) equated for the offer of a tobacco quitline referral and 8 weeks of free nicotine patch for those who engage in quitline treatment, 2) to conduct a preliminary smoking cessation, randomized controlled trial (RCT) with 100 people living with HIV (PLWH) who smoke cigarettes, comparing CI-METQ vs. NC, with predictions that CI-METQ relative to NC will result in increased readiness, higher rates of tobacco treatment engagement, more quit smoking attempts and higher rates of 7-day point prevalence abstinence rates at 1-, 3- and 6-month follow-ups. Health-related quality of life over this period will also be examined, and 3) to examine CI-METQ's effects on key mechanisms during the computer session and their associations with tobacco treatment engagement and smoking outcomes at 1- and 3-month follow-ups.
This study will implement and test the effectiveness and cost-effectiveness of a tobacco cessation intervention (Academic Detailing + Integrated Tobacco Order Set - AD + ITOS) for adults admitted to the hospital. The intervention will begin during the hospital stay and continue after discharge. The intervention will use resources easily available to most acute care hospitals: computerized physician order entry, physician and nurse education, staff meetings for physicians, nurses and allied health professionals, online learning capabilities, faxing to primary care providers (PCPs), and the telephone counseling and support available from a state smokers' quitline (QL). The investigators hypothesize that the subjects in the intervention arm (AD + ITOS) will be more likely to achieve tobacco abstinence at 12 months post hospital stay than subjects in the control arm (Academic Detailing - AD). Tobacco abstinence will be assessed by self report and biochemical verification (exhaled carbon monoxide reading).
Nurse-administered smoking cessation interventions have been shown to be efficacious, but are seldom implemented due to lack of training and time. This project aims to disseminate and test the nurse-administered Tobacco Tactics intervention in 6 hospitals.
Lung cancer is the leading cause of cancer death in the United States. Currently it remains impossible to predict which smokers will get cancer. Each puff of a cigarette delivers a mixture of over 60 known carcinogens. Biomarkers that quantify carcinogen levels and metabolism are a useful tool and available to use. The purpose of this study is to assess the variability of tobacco smoke carcinogen biomarker levels over one year in a group of smokers.
The purpose of this study was to estimate changes in biomarkers of exposure (BOE) in adult cigarette smokers using an oral tobacco-derived nicotine (OTDN) product relative to adult smokers who continue smoking exclusively.
This trial uses an Experimental Tobacco Marketplace to study the purchase of tobacco products in menthol cigarette smokers. Determining the level of substitutability of both flavored and unflavored/tobacco flavored e-cigarettes when menthol cigarettes are available and unavailable can help determine if a flavor ban (of either menthol cigarettes and/or flavored e-cigarettes) will lead to smoking cessation and/or harm reduction. A greater understanding of tobacco product purchasing could help inform possible regulatory actions by the Food and Drug Administration.
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.
This is a pilot study to test the feasibility of conducting a text based smoking cessation trial with Emergency Department patients who are smokers.
This study examines the potential effect of reducing nicotine content or menthol or both in women of reproductive age, a vulnerable population identified by the FDA in need of further research.
The project is designed to examine the effectiveness of strategies to increase access to treatment for tobacco use and dependence among rural Veteran smokers. In addition, it will examine whether tailored treatment that is designed to address common comorbid conditions that are related to cigarette smoking enhances success with quitting relative to enhanced standard of care. The investigators hypothesize that participants assigned to the tailored tobacco cessation intervention will report greater cessation rates at six months. The investigators also anticipate more favorable outcomes on measures of depressive symptoms, alcohol use, and body weight.
This nationwide telephone and mail- based research study will recruit 1,400 cigarette smokers who are not motivated to quit to test the effects of a marketed oral, non-combustible smokeless tobacco product on cigarette smoking behaviors. It will also track the participants' usage patterns of the smokeless tobacco product. Half of the participants will receive a new, potentially safer tobacco product during the first six weeks of the study, and half will not. During this six-week period, each participant will complete three brief phone interviews. After this first six week period, participants will complete 6 other brief follow-up interviews, where they will answer questionnaires about their smoking habits.
The purpose of this study is to develop an evidence-based Tobacco Tactics website tailored to veterans based on an intervention tested in the VA.
The purpose of the present study is to examine the pharmacokinetics and pharmacodynamics of "tobacco-free" oral nicotine pouches, at various doses and flavors, in healthy adult smokers. The study will utilize a within-subjects, double-blind design. Upon enrollment, participants will complete 7 dosing conditions: tobacco-flavored pouch (low or high nicotine dose), mint/menthol-flavored pouch (low or high nicotine dose), and fruit-flavored pouch (low or high nicotine dose); participants will also complete a condition where the participants will smoke participants' preferred brand of cigarettes. In each experimental session, participants will complete 2 product-use bouts. In bout 1, the participants will use a single product (pouch or cigarette) for a fixed period under controlled conditions. In bout 2, participants will be given 2 hours to use participants' assigned product ad libitum.
There are significant barriers to tobacco cessation treatment for patients and providers in specialty care clinical settings. Specialty providers cite several barriers to delivering evidence-based tobacco cessation care, including insufficient time and lack of training. In addition, a large proportion of patients who begin tobacco cessation treatment do not quit. Use of healthcare technology (i.e., telehealth, electronic health record, and computerized treatment algorithms based on patient data) to improve patients' ability to quit tobacco use. The purpose of this study is to demonstrate the feasibility of a larger trial, and to evaluate the acceptability of the intervention design. Thirty participants will be assigned to receive either 1) a treatment that includes personalized counseling, tobacco cessation medications, and text messaging; or 2) referral to Department of Veterans Affairs' Quitline program plus SmokefreeVET, a text messaging program.
The purpose of this study is to assess changes in exposure to selected harmful and potentially harmful substances related to tobacco/nicotine use when adult smokers switch from their usual brand of combustible cigarettes to the myblu e-cigarette, for up to 56 days. This study is designed as an open-label, partially-randomized, parallel-arm, multi-site study in healthy adult smokers. Some subjects will be selected to take part in additional procedures as part of a pharmacokinetics (PK) sub-study.
Pilot study to test feasibility of delivering a motivational smoking cessation intervention to low income smokers via a computer tablet.
The purpose of this study is to examine whether or not providing Chantix (varenicline) will help African American smokers quit smoking.
