This suggests medications with alternative mechanisms of action should be explored to address this unmet need. Substantial preclinical research indicates that orexin antagonism blunts the internally and externally triggered motivation to attain abused substances. This research project will translate these preclinical findings into the clinical domain by administering the FDA approved orexin antagonist, suvorexant, to those with a substance use disorder. Suvorexant s ability to blunt neurobiological correlates of substance misuse will be assessed. This will be assessed following acute and repeated drug administration. Baseline individual differences will be considered to determine whether neurobiological variance influences suvorexant s impact in those with nicotine dependence. In an independent arm, the interaction between suvorexant and a dopamine agonist (methylphenidate) on cognitive function will be assessed in non-smoking individuals.\n\nObjectives:\n\nThe objective is to determine the acute and chronic impact of the orexin antagonist, suvorexant, on neurobiological and behavioral factors linked with substance use disorders. Whether such effects are mediated by baseline characteristics will be tested. Given suvorexant is an FDA approved treatment for insomnia, sleep will be evaluated as well in the nicotine dependent arm.\n\nEndpoints:\n\nIn nicotine-dependent individuals, suvorexant s impact on brain function will be assessed several ways by evaluating: 1) resting function, 2) reactivity to drug cues, 3) reactivity to non-drug related cognitive tasks. Sleep and nicotine use will be measured throughout the study period. In those without nicotine-dependence, the impact of suvorexant and the interaction of acute methylphenidate and suvorexant on brain function will be assessed. This arm will provide insight into how suvorexant impacts reward\u002Fcognition as well as impacts the pharmacological influence of methylphenidate on those same measures.\n\nStudy Population:\\\u003CTAB\\>\n\nNicotine dependence arm:140 subjects; Volunteers who are between the ages of 18-60 and are daily smokers\u002Fvapers.\n\nControl arm: 80 subjects; Volunteers who are between the ages of 18-60 and are non-smokers\u002Fvapers\n\nThis study will be conducted at the NIDA-IRP, Biomedical Research Center, in Baltimore, MD.\n\nDescription of Study Intervention:\n\nNicotine dependence arm: Suvorexant at 10 mg single dose, and Suvorexant at 10 mg daily for approximately 7 days.\n\nControl arm: 1.

Unlike electronic cigarettes (ECs) ONPs have no impending regulatory barriers with regard to flavoring or nicotine dose, and manufacturers have capitalized on this by introducing an extensive slate of characterizing flavors and nicotine concentrations. Both sales trajectory and the surge in marketing suggest ONP use is likely to increase in the coming years. Work by the investigators and others indicates that interest in these products is high among current EC users, and among specific demographic groups including those who identify as sexual and gender minority (SGM). ONP use is discrete and so can function as a secondary source of nicotine, encouraging dual use patterns and more severe nicotine dependence. Depending on the use patterns of ONPs that emerge, regulation of ONPs may serve the public health interest. However, very little is known about factors relevant to the actual appeal and abuse liability of these products. The investigators propose to address this important gap by assessing the appeal and abuse liability of gum and pouch ONPs as a function of flavor (mint vs fruit) and nicotine concentration (2mg vs. 4mg). Flavor and nicotine strength, along with product type, are regulatable attributes, and so it is essential to understand their impact on appeal and abuse liability. Evidence from EC use suggests a potential interaction between flavor and nicotine strength, with flavorants in the \"mint\" category desensitizing receptors integral to the aversive sensory experience of nicotine, leading to greater tolerability of high nicotine concentration. Because of current ONP marketing emphasis on youth, the investigators will recruit young adult exclusive EC users (N = 320; ages 21 - 25). The investigators will target recruitment of a sufficient number of SGM participants (N = 64, 20% of sample) to allow assessment of potential differentiation of this group. Participants will complete one virtual session focused on assessment of the sensory appeal of ONPs. Based on individual participant ratings, the preferred fruit and the preferred mint ONP will be selected (from their randomized product type and nicotine strength) to each be assessed in a single-product session examining factors known to predict abuse liability (relief of withdrawal, liking, behavioral economic indices of demand, and follow-up naturalistic product use). The investigators will pay particular attention to evidence suggesting dual use potential of ONPs, given its association with greater severity of nicotine dependence.

Structural barriers, including stigma related to attempting to quit, limited financial and time resources, low awareness of the health risks associated with tobacco smoking- and vaping-reduce engagement with traditional services. TUBSIS 2.0 aims to address these access inequities by providing a fully remote, anonymous and free internet-based program tailored to diverse adult populations in both countries.\n\nObjectives:\n\nThe \"TUBSIS 2.0: An Adaptation Study of Tobacco Addiction Support Programme - TUBSIS for Tobacco Users in Switzerland and Türkiye\" project aims to support readiness to reduce or quit tobacco smoking\u002Fvaping, improve well-being and self-compassion and strengthen health-related behaviors. The intervention targets German-, English-, and Turkish-speaking adults and includes mindfulness-based strategies for quitting or reducing tobacco smoking and vaping. Motivation to cease tobacco smoking\u002Fvaping varies considerably across the lifespan. Younger individuals may perceive smoking\u002Fvaping cessation as unnecessary, often due to limited awareness of long-term health risks or a sense of invulnerability. In later adulthood, although addiction tends to be more deeply established, many individuals hesitate to attempt cessation because of concerns about the psychological and behavioral challenges associated with the process. It is therefore essential to provide individuals with support that helps them understand the cessation process, prepare for the challenges that can be expected and identify strategies that align with their psychological needs. Such strategies may include stress management and self-compassion practices that can be utilized before, during and after cessation attempts. TUBSIS 2.0 offers structured and accessible guidance to support this preparation by providing a clear, evidence-based pathway for individuals at different stages of readiness to change.\n\nMethods:\n\nTUBSIS 2.0 is a web-based, individual and asynchronous program consisting of eight modules delivered over four weeks. A total of 406 participants will be recruited and randomly assigned to either the intervention or control group. Data are collected anonymously at four measurement points (baseline, mid-term, post-term and 8-week follow-up) from participants. The program focuses on supporting participants' reducing or quitting tobacco smoking or vaping; to increase their readiness for smoking\u002Fvaping cessation, mental well-being, self-compassion and stress management with mindfulness strategies.\n\nWithin the Health Action Process Approach (HAPA), the process of behaviour change is conceptualised as a dynamic, non-linear process that progresses through motivational and volitional phases. TUBSIS 2.0 has been adapted to reflect this structure by integrating phase-specific components. These components include modules that enhance risk awareness and outcome expectancies, planning and self-regulation tools to support action initiation and mindfulness-based strategies that are embedded throughout all phases to strengthen self-efficacy and coping. By addressing these shifting needs across the change process, the programme provides a responsive and theory-driven pathway for reducing\u002Fquitting tobacco smoking or vaping.\n\nRelevance:\n\nTUBSIS 2.0 is highly relevant to public health priorities, as it provides a cost-effective, scalable and environmentally sustainable intervention that eliminates barriers commonly associated with traditional cessation services. By requiring no travel, printed materials or in-person appointments, the programme offers equitable access to adults across all age groups, genders and diverse migrant communities in Switzerland and Türkiye. Its multilingual and culturally adapted structure addresses significant service gaps for populations that are underserved or hesitant to seek conventional support. By reducing tobacco smoking- or vaping-related harm and facilitating early behavioural change, TUBSIS 2.0 has the potential to decrease long-term healthcare costs while expanding access to evidence-based digital prevention tools.",[373,30,215,529],"Smoking Tobacco",[531,221,532,533,534],"smoking tobacco","web-based intervention","mindfulness","Health Action Process Approach",{"date":536,"type":38},"2026-05-05",{"date":538,"type":38},"2025-11-15",{"date":540,"type":23},"2026-08-31",{"name":542,"class":45},"University of Zurich",{"id":544,"slug":545,"hasResults":12,"nctId":546,"briefTitle":547,"officialTitle":548,"acronym":4,"eligibilityCriteria":549,"healthyVolunteers":18,"sex":19,"minAge":20,"maxAge":55,"enrollmentInfo":550,"targetDuration":4,"studyType":24,"phases":552,"briefSummary":553,"conditions":554,"keywords":4,"overallStatus":34,"whyStopped":4,"lastUpdateSubmitDate":555,"lastUpdatePostDateStruct":556,"startDateStruct":558,"completionDateStruct":560,"leadSponsor":562,"locationsCount":46},"100484386","phase-4-beta-adrenergic-modulation-of-drug-cue-reactivity-100484386","NCT05587361","Beta-Adrenergic Modulation of Drug Cue Reactivity","Beta-Adrenergic Modulation of Drug Cue Reactivity: Neural and Behavioral Mechanisms","Inclusion Criteria:\n\n1.

Extensive clinical research has confirmed that tobacco exposure is a significant independent risk factor for perioperative complications. Epidemiological data indicate that long-term smokers experience a significantly higher all-cause mortality rate during hospitalization, approximately 20% greater than non-smokers, while the incidence of postoperative complications is 40% higher. Consequently, international guidelines universally recommend the establishment of standardized preoperative smoking cessation programs for surgical patients. Nicotine withdrawal, a typical clinical manifestation during smoking cessation, involves symptoms across multiple systems: neuropsychiatric symptoms such as mood depression, sleep disturbances, and irritability; autonomic dysfunction leading to postural dizziness and bradycardia; and metabolic dysregulation resulting in increased appetite and weight gain. Notably, these withdrawal symptoms exhibit a significant time-dependent pattern, typically peaking 24-72 hours after cessation. Multicenter studies have demonstrated that tobacco-dependent patients experience an average increase of IV Abstract 35-45% in opioid consumption within 24 hours postoperatively, with the duration of analgesic requirements extended by approximately 25%. However, some patients suffer from severe adverse reactions to opioids (e.g., nausea, vomiting, confusion), making the use of adjuvant medications for multimodal analgesia and optimized pain management particularly crucial.
