341 Clinical Trials for Various Conditions
After initial eligibility screening, Veterans who use both cannabis and tobacco will be randomly assigned to receive either varenicline (Chantix) or placebo for 12 weeks. Participants will attend weekly visits, in person or remotely, to provide breath and urine samples for testing, fill out questionnaires, and meet with study staff about medication compliance.
The purpose of this community-based study is to evaluate the effectiveness of a culturally-tailored smoking cessation treatment for American Indian (AI) smokers as compared to standard evidence-based cessation treatment (not culturally-tailored).
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.
The objective of this study is to determine the effectiveness of ED initiated NRT on tobacco cessation point abstinence rates as reported by patients at 2 weeks and 1 month post randomization, and continued abstinence rates at 3 months compared to standard of care therapy.
The purpose of the study is to examine whether an investigational medication called ketamine is able to improve treatment outcomes for tobacco use disorder when delivered in conjunction with brief motivational enhancement therapy. Participants will receive ketamine assisted motivational enhancement therapy weekly for three weeks and there will be 2 follow up visits. All visits will also consist of questionnaires and saliva samples will be taken. The overall participation will last approximately 8 weeks.
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.
Many people living with HIV (PLWH) smoke. Smoking in these individuals is often undertreated. This study plans to assess the ability of various clinical pathways involving tobacco treatment medications and contingency management (paying smokers for not smoking) to improve smoking cessation in a group of PLWH.
The purpose of this study is to determine if brain stimulation using repetitive transcranial magnetic stimulation (rTMS) directed at different parts of the brain can decrease feelings of cigarette craving and symptoms of cigarette withdrawal, and also if men and women have different responses to rTMS. Participants will visit the University of California, Los Angeles (UCLA) five times: First, for in-person screening, then for four rTMS sessions, four three different brain regions. Everyone in the study will be assigned to all four treatment arms and they will take place in a random order. Before and after each rTMS session, a brief MRI will be performed, and participants will be asked to fill out questionnaires that describe how they are feeling.
This proposal will obtain preliminary data on the effect of a single sub-anesthetic dose of a sedative on cigarette craving and smoking behavior as well as measuring tolerability and acceptability.
The purpose of this protocol is to examine whether mifepristone, a medication with glucocorticoid receptor antagonist activity, may be a potential treatment for Tobacco Use Disorder (TUD). Mifepristone has already shown promise as a potential treatment for PTSD (1) and alcohol use disorder (AUD) (2), but no previous studies have examined the therapeutic potential of mifepristone for TUD. This will be a double-blind, placebo-controlled study on the effects of a 7-day treatment with 600 mg mifepristone, or placebo, on cognitive function, tobacco withdrawal severity, and smoking behavior.
The purpose of this study is to assess the effects of administering N-Acetylcysteine (NAC) to assist in initial cessation and/or relapse prevention in adult cigarette smokers.
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 study is a randomized crossover trial. Current smokers will complete a session with each product: usual brand cigarette, e-cigarette, and heat-not-burn. The objective of this survey is to assess for ongoing use of study products and is part of safety monitoring.
The study is being done to determine whether an in-hospital intervention using a brief intervention to facilitate quitline utilization will increase quitline utilization by hospitalized smokers, and will increase post hospital discharge smoking abstinence rates. Study participants will be randomized to receive either a brief quitline facilitation intervention , or a control intervention of a brief stop-smoking message. The study will also compare healthcare costs and utilization in the first six months following hospitalization between the two groups.
Smokers have three choices when faced with surgery: keep smoking, quit for a short time around surgery or quit for good. In the first specific aim, a decision aid was designed to help facilitate the discussion of these choices between smokers and healthcare providers. This second aim will test whether this decision aid improves the decisional quality compared with standard methods used to discuss perioperative smoking.
The goal of this project is to evaluate the effectiveness of a family-based tobacco use prevention intervention directed at immigrant Latino parents of middle school aged youth as delivered in partnership with seven community organizations. The primary outcomes of the study are youth susceptibility to tobacco use, and changes in parenting practices among the parents of the youth. The planning, initiation, and delivery of the intervention will occur in collaboration with community organizations that have identified this project as important to the families they serve. Though the collaboratively designed training curriculum has been successfully tested and a study design for the current project established, a substantive development period for this project will allow the research team and collaborating organizations to consider key aspects of design and delivery.
In this project we will conduct a pilot study of a brief intervention to reduce teen tobacco, alcohol and drug use that primary care dental practitioners can provide in their offices.
The hypothesis underlying the proposed study is that the blunted endothelium-dependent vasodilation seen in the airway of current smokers is also present in the brachial artery, and that the same inhaled corticosteroid (ICS) treatment regime that reversed endothelial function in the airway of current smokers will also restore endothelium-dependent relaxation in the brachial artery. Non-smokers will be used as controls and will not receive any intervention or treatment.
The investigators want to find out if providing a Community Health Educator Referral Liaison (CHERL) helps practices help their patients change risky behaviors (tobacco use, physical inactivity, unhealthy diet, and risky drinking) by connecting patients to available services in the community or directly providing behavior change support.
To test the feasibility of an intensive behavioral and pharmacologic tobacco cessation program for radiation oncology patients and their families/companions.
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.
