31 Clinical Trials for Tobacco Use Disorder
Future Self-BD is a 6-session virtual intervention that encourages participants to vividly generate personal and positive future events that they anticipate may be benefited by smoking cessation. Each session will be conducted on HIPAA-compliant Zoom and led by the PI (Dr. Gold).
The proposed project will include enrollment of 200 daily tobacco cigarette users, ages 22+, from the San Diego community. Participants will be assessed on the VR Nicotine Cue Exposure paradigm then randomized (stratified on age and sex) to receive varenicline (target dose 1mg twice daily) or placebo (n per group=100; total N=200). Following eight days of titration, participants will be assessed again on the VR Nicotine Cue Exposure paradigm. They will then be followed via mobile assessments for eight days on target dose of varenicline, and 30-days post assessment by phone, to assess short-term nicotine use behaviors.
The goal of this clinical trial is to to inhibit the dorsal anterior insula (dAI) with low intensity focused ultrasound (LIFU) to determine the causal role for the dAI in smoking cue induced craving in individuals with tobacco use disorder (TUD); smoking cue induced craving is a clinically important behavior which has been associated with the severity of nicotine addiction. The main question\[s\] it aims to answer are: * the safety and tolerability of dAI LIFU compared to sham stimulation in individuals with TUD * the effects of LIFU vs sham to left dAI functional magnetic resonance imaging (fMRI) BOLD activity and craving in response to smoking cue exposure. Participants will undergo anatomical MRI, neurological assessment, clinical assessment and patient query to assess the safety and tolerability of LIFU vs sham. Participants will undergo functional magnetic resonance imaging where we will measure the effect of LIFU vs sham on 1) dAI blood-oxygen-level-dependent (BOLD) activation in response to smoking (compared to neutral) cue exposure and 2) cue-induced craving in individuals with TUD. Each participant will receive LIFU and sham stimulation.
Double-blind, placebo-controlled, randomized mechanistic clinical trial to test an intravenous dose of either ketamine, midazolam, dexmedetomidine, or a placebo (saline) on cigarette smoking behavior, craving, and neural effects.
This is a multi-site, double-blind, randomized clinical trial of the 5-HT2A receptor agonist psilocybin for smoking cessation. Four sites with experience in conducting psilocybin research will be involved in this trial: Johns Hopkins University (JHU), the University of Alabama at Birmingham (UAB), New York University (NYU), and Sheppard Pratt (SP). The proposed study will treat 66 participants (22 at each site), randomized to receive either: 1) oral psilocybin (30 mg in session 1 and either 30 mg or 40 mg in session 2); or 2) oral niacin (150 mg in session 1 and either 150 mg or 200 mg in session 2), with sessions 1 week apart.
The purpose of the RECLAIM study is to evaluate the effectiveness of varenicline (sometimes known as Chantix) compared to placebo (an inactive substance) for the treatment of cigarettes and cannabis (marijuana). Varenicline is not FDA approved for the combination treatment of cigarette abstinence and cannabis reduction or abstinence. All participants will also receive counseling and access to online treatment modules during a quit attempt for cigarettes and a reduction attempt for cannabis. This study is being conducted by the Medical University of South Carolina. All procedures are conducted remotely and there is no in-person visits are needed. To qualify, participants must be 18 or older, live in South Carolina, use cigarettes and cannabis, and are interested in quitting cigarettes and reducing cannabis.
The goal of this study is to design and test the first mobile contingency management (CM) smoking cessation intervention for military Veterans undergoing major elective surgery. Smoking is the leading risk factor for postoperative complications and is associated with longer hospital stays, reoperations, and 30-day mortality. Smoking rates among patients undergoing major elective surgery are high, 22.3-43.0%. It is imperative to identify efficacious, strategically timed smoking cessation interventions for surgery patients. CM incentivizes smoking cessation through positive reinforcement (rewards) when bioverified abstinence is achieved. To ensure feasibility, CM must be tailored to the clinical context. CM for smoking cessation has never been delivered before and after major surgery, nor has mobile CM bioverification been trialed perioperatively. The investigators will develop and test a tailored mobile smoking cessation CM protocol for Veterans undergoing major elective surgery.
Cigarette smoking remains the leading cause of preventable morbidity and mortality in the US. Use of multiple tobacco products is becoming increasingly prevalent, with dual use of e-cigarettes and cigarettes representing the most common combination. Though e-cigarettes are not without risk, completely switching from cigarettes to e-cigarettes likely reduces risk for tobacco-related harm. However, many established dual users maintain long-term smoking and the majority who use e-cigarettes non-daily are at an even greater risk for prolonged smoking than exclusive cigarette smokers. The Food and Drug Administration Center for Tobacco Products (FDA CTP) has announced plans to implement a nicotine-limiting product standard, capping the nicotine in cigarettes at a minimally or non-addictive level. Randomized controlled trials (RCTs) demonstrate that adults who exclusively smoke cigarettes respond to very low nicotine content (VLNC) cigarettes with reductions in smoking, demand, and dependence. However, nicotine reduction RCTs to date have excluded people who regularly use e-cigarettes and therefore it remains unclear how a nicotine-limiting standard for cigarettes would affect smoking among dual users. Given the potential substitutability of e-cigarettes for cigarettes, reducing the nicotine in cigarettes could promote a transition to exclusive e-cigarette use among dual users unable to completely quit nicotine, but only if sufficiently appealing e-cigarettes remain available. E-cigarettes containing 5% nicotine-salt solution are currently most popular in the US, but policy makers have proposed restricting e-cigarettes to ≤ 2% nicotine to curb youth e-cigarette use, and several states have already set limits to reduce nicotine in e-cigarettes. Prior laboratory studies indicate that higher vs lower nicotine e-cigarettes serve as better substitutes for cigarettes among adult dual users. As such, a restriction on e-cigarette nicotine concentration could undermine the potential for e-cigarettes to substitute for cigarettes and diminish the benefits of a nicotine-limiting standard for cigarettes among dual users. This study is a 12-week double-blind 2 cigarette level (Normal Nicotine vs Very Low Nicotine) x 2 e-cigarette level (High Nicotine vs Low Nicotine) between-subjects factorial trial to investigate how a nicotine-limiting standard for cigarettes affects adult dual users and whether these effects are impacted by constraints on e-cigarette nicotine concentration. Outcome measures include cigarettes per day, cigarette dependence, and toxicant exposure. The research is highly relevant to FDA CTP domains of Addiction and Behavior because it will test whether reducing the nicotine content of cigarettes reduces smoking and dependence, and whether these effects are moderated by the availability of high vs low nicotine e-cigarettes.
Tobacco use among US Veterans poses significant health problems and challenges to their overall well-being. The aim of this project is to evaluate the effectiveness of a program called Contingency Management (CM) in helping Veterans quit smoking during lung cancer screening or cancer care at VA clinics. CM is a behavioral treatment that uses rewards to encourage smoking cessation when verified through biological testing. In the first year, the researchers will develop a mobile CM protocol based on feedback from Veterans and healthcare staff through focus groups. In the second year, they will conduct a pilot study to test the feasibility of the mobile CM program along with counseling and medication for 20 Veterans over a five-week period. The success of the pilot study will determine whether to proceed with a larger randomized controlled trial (RCT) in years three to six, comparing the efficacy of mobile CM with standard treatment. The project will take place at SFVA.
The goal of this project is to better understand the relationship between tobacco/nicotine and cannabis using behavioral economics during a tobacco/nicotine quit attempt. All participants will receive tobacco/nicotine cessation treatment (smoking and/or vaping treatment) for 12 weeks. To qualify, participants must be between the ages of 18-25 and use tobacco products (smoke cigarettes and/or vape nicotine) and use cannabis (in any form). Participants do not need to be interested in quitting cannabis/marijuana to qualify. This study is being conducted by the Medical University of South Carolina. All procedures are conducted remotely and there is no in-person visits are needed.
The goal of this research is to evaluate the efficacy of cannabidiol (CBD) in reducing cigarette smoking. Although there are safe and effective treatments for smoking cessation, not everyone who attempts smoking cessation is successful, even with these treatments. Relapse rates are high, leaving a need for new approaches. Despite justification to evaluate CBD for this indication, human research on the topic is scant. Larger, more extended studies are warranted and essential. The investigators will recruit participants from CRI-Help, Inc., a substance abuse treatment program in North Hollywood, where residents who indicate the desire to stop smoking are prohibited from using other cannabis products which would affect recruitment. The aims of this study are: 1. Evaluate the effects of CBD on changes in cigarette use throughout and following the trial. 2. Exploratory Aims. Measure plasma concentrations of CBD, N-arachidonoyl-ethanolamine (anandamide) and 2-arachidonoylglycerol (2-AG) throughout the trial. Participants who meet eligibility criteria will take part in a 56-day treatment phase during which they receive the study medication under supervision (CBD or placebo twice daily) and complete questionnaires on side effects, withdrawal, craving and mood symptoms. Blood, breath, and urine tests will also be performed throughout the study. Participants who complete the treatment will also be assessed at 1-month and 3-month follow up visits.
Tobacco use is the number one preventable cause of the death in the United States, and is high among US Veterans, and those who have experienced trauma are more likely to smoke. Despite the efficacy of current evidence-based treatments for smoking cessation, there is a critical need for alternative treatments. This project seeks to evaluate the feasibility and effectiveness of a smoking cessation treatment for Veterans with posttraumatic stress disorder (PTSD) who smoke. The treatment combines smoking cessation counseling, nicotine replacement therapy (e.g., nicotine gum), and repetitive transcranial magnetic stimulation (rTMS). rTMS is a noninvasive brain stimulation treatment that has been cleared by the Food and Drug Administration for smoking cessation in adults.
This study is designed to investigate the effects of a beta-adrenergic antagonist (Propranolol; 40 mg IR) and nicotine patch (14 mg) administered alone and in combination on neurobiological and behavioral responses to smoking cues in ongoing cigarette smokers. This is a basic experimental study in humans and participants will not take these medications for an extended period or make a cessation attempt as part of their involvement in this research project.
The study team will conduct a Multisite Randomized Controlled Trial to evaluate the advantages and disadvantages of two approaches for quitting smoking among people with serious mental illness (SMI). The study will compare a novel app tailored to people with SMI, Quit on the Go, to a standard of care smoking cessation intervention. We will test the effectiveness of the Quit on the Go app, an intervention that has demonstrated feasibility and acceptability in the target population, as a tool for smoking cessation in people with SMI. Participants with SMI will be recruited across 3 sites (Duke University, Univ. at Buffalo, and Wake Forest University).
The purpose of this study is to evaluate the effectiveness of two behavioral interventions on smoking behavior - Mindfulness-Oriented Recovery Enhancement (MORE) and Cognitive Behavioral Therapy (CBT). MORE is a behavioral therapy that integrates mindfulness training to modify reward processes. CBT is a therapy designed to help individuals understand how their thoughts and feelings influence their behaviors.
This research study is looking into the effects of clavulanic on smoking behavior in adult cigarette smokers. The primary study hypothesis is that, compared to placebo, clavulanic acid will reduce smoking over the course of the study.
This clinical trial studies the effects, appeal, and abuse liability of 6-methyl nicotine (metatine) electronic cigarettes among young adults.
This study evaluates how synthetic cooling additives like WS-3 and WS-23 impact e-cigarette perceptions, use behavior, and toxicant exposure.
The purpose of this study is to better understand tobacco outcomes using a commonly prescribed stop smoking medication (varenicline) and financial incentives for adults who also use cannabis. Varenicline is not FDA approved for e-cigarette cessation, but is FDA approved for cigarette cessation. Investigators are also interested in how cannabis/marijuana and tobacco interact during a tobacco quit attempt. All participants will receive e-cigarette cessation treatment for 12 weeks. To qualify, participants must be between the ages of 18-40 and use both e-cigarettes and cannabis. Participants do not need to be interested in quitting cannabis to qualify. This study is being conducted at three sites: the Medical University of South Carolina in Charleston, SC, Behavioral Health Services in Pickens, SC, and MUSC Lancaster in Lancaster, SC.
The goal of this observational study is to learn how the brain's information processing changes during and following administration of serotonergic psychedelics (psilocybin, N,N-Dimethyltryptamine/DMT, Lystergic Acid Diethylamide/LSD, etc.) for people with and without mental illness receiving serotonergic psychedelics through any clinical trial at Yale University. The main questions it aims to answer are: 1. Do serotonergic psychedelics cause the brain to rely on new information more than previously learned information while under the influence? What about 1 day, 5-14 days, and 4-6 weeks after use? 2. Do serotonergic psychedelics cause long-lasting side-effects in how people perceive (see, hear, feel, etc.) the world and how easily people change their beliefs? 3. How does the brain's electrical activity change after using serotonergic psychedelics? How does the balance between excitation and inhibition change while under their effect? 4. Can changes in how the brain uses information predict who will benefit from a psychedelic and who will have side effects from psychedelics? Researchers will compare with people given placebos to see what changes in brain processing are unique to serotonergic psychedelics. Participants will have the opportunity to do some combination of the following: 1. Online computer assessments consisting of games and questionnaires that probe how participants think. 2. Magnetoencephalography (MEG) or electroencephalography (EEG) with eyes closed and with repeated clicks, images, or sensations delivered. 3. A magnetic resonance imaging (MRI) scan. 4. Semi-structured qualitative interviews about their experience after taking a serotonergic psychedelic recorded via Zoom.
This study will randomize 64 non-treatment seeking individuals who smoke cigarettes daily in a double-blind, placebo-controlled laboratory study testing the effects of cytisinicline on the neural substrates of cigarette cue reactivity.
This study seeks to determine the feasibility, acceptability, and preliminary efficacy of an intervention consisting of off-label use of a medication with strong efficacy data for alcohol use disorder (AUD) with medical management and a clinical pharmacist-delivered behavioral intervention in reducing alcohol use among individuals with HIV and AUD.
Cannabidiol is a compound found in cannabis plants that is well tolerated, has low abuse liability, and might be an effective medication to promote tobacco cessation. This clinical study will use a validated approach for screening tobacco cessation medications to determine if oral cannabidiol increases short-term tobacco abstinence, and evaluate mechanisms that might explain how cannabidiol alters smoking behavior. Results from this study will provide data on the therapeutic potential of cannabidiol for tobacco cessation.
This is a research study about a smoking cessation program tailored for adults with serious mental illness (SMI). The program uses a Videogame-based Physical (VIP) activity, smoking cessation counseling, and medication (bupropion),
This study investigates the feasibility, acceptability, and short-term effects of providing 4 weeks of complimentary electronic cigarettes (ECs) to 30 individuals who did not quit after smoking cessation treatment provided in the context of lung cancer screening and do not plan to quit smoking. This open-label single-arm pilot clinical trial will test the impact of EC provision on: 1) study feasibility, 2) EC acceptability, 3) tobacco use behavior (e.g., cigarettes per day, EC use), and 4) biomarkers (e.g., carbon monoxide, cotinine, and anabasine). Participants will be asked to switch from combustible cigarettes to the NJOY ACE 5% nicotine electronic cigarette (EC) for 4 weeks. They will be followed an additional 4 weeks after EC provision ends (to 8 weeks). The first study hypothesis is that more than 40% of eligible smokers who are offered participation in the trial will enroll, and that 75% of enrollees will complete the trial. The second study hypothesis is that participants will report fewer cigarettes smoked per day at the end of 4 weeks of EC provision, relative to their baseline values.
Cigarette smoking is a significant public health concern. Transcranial magnetic stimulation (TMS) is a non-invasive form of brain stimulation that has already displayed remarkable potential for producing novel, non-pharmacological interventions for depression and cigarette smokers. In this study, investigators will use brain MRI to guide TMS therapy for smoking cessation.
The goal of this research is to determine how removal of little cigar and cigarillo (LCC) flavor descriptors on packaging impacts attention and affective responses to LCC warnings. A study will be conducted using eye tracking, electrodermal activity (galvanic skin response), and survey measures of affect to measure participant responses to LCC packages varied by warning type (pictorial vs. text only) and flavor contents ('Sweet' flavor descriptor vs. no flavor descriptor).
Mobile health (mHealth) will be used for early detection of oral cancer and pre-cancer lesions, and to improve awareness of oral cancer among the population and knowledge of oral cancer diagnosis among frontline health providers. This program is inclusive of long term surveillance to downstage oral cancer in India
This project will evaluate a proactive outreach intervention for tobacco cessation among primary care BIPOC populations who smoke in two health systems across the region. Compared with Whites, BIPOC populations in the US experience disproportionate health consequences from commercial cigarette use. Few evidence-based cessation treatments (EBCTs) have been specifically developed, evaluated, or implemented for BIPOC populations. Moreover, uptake of EBCT (e.g. medication, counseling) is lower among BIPOC populations. Reasons for the failure to engage BIPOC patients in EBCTs are complex and multi-level (e.g., patient, provider, healthcare system). To address these gaps, the investigators will assess the added effectiveness of an approach to augment the standard of care with longitudinal proactive outreach to connect BIPOC adults with EBCT. The proposed multi-level intervention leverages the electronic health record to identify patients who smoke, who can then be proactively engaged via culturally tailored outreach to connect them to EBCT. The proactive approach may circumvent experiences of bias within the healthcare system and thus enhance engagement.
The study is measuring Cardiovascular effects of very low nicotine content cigarettes on daily and non-daily smokers
