NCT ID: NCT04226404 Completed - Smoking Clinical Trials

CSD190501: A Study to Determine Subject Puffing Patterns of an Electronic Nicotine Delivery System in an Ambulatory Setting

Start date: January 14, 2020
Phase: N/A
Study type: Interventional

This study will be a single-center, controlled, open-label, parallel study to evaluate the puffing patterns of healthy adult consumers of tobacco products switching from a usual brand (UB) Electronic Nicotine Delivery Systems (ENDS) product to an ENDS Investigational Product (IP) product with 4.8% nicotine over a three-week ambulatory period. This study will be conducted in support of a Premarket Tobacco Product Application (PMTA) ENDS submission to the US Food and Drug Administration (FDA) Center for Tobacco Products (CTP).

NCT ID: NCT04226352 Completed - Smoking Cessation Clinical Trials

Three Dosing Regimens of Dextromethorphan (DXM) Reportedly Used in Major Depressive Disorder

Start date: March 15, 2020
Phase: Phase 1
Study type: Interventional

This is an open-label dosing pilot study of 15 patients aged 18-50 years of age with diagnoses of Major Depressive Disorder (MDD) randomized to 1 of 3 treatment arms. The study will consist of a screening evaluation performed within the course of 2 weeks, followed by an active treatment period of 28 days where treatment arm 1 will take a supervised dose of 300mg DXM every 14 days for 28 days, treatment arm 2 will take the FDA approved maximum daily ingestion for cough (60mg DXM) daily for 28 days, and treatment arm 3 will take 1 supervised dose of 300mg DXM and 60mg for the remaining 28 days. After the active treatment period, subjects will be followed for 65 days with safety and psychiatric assessments at designated timepoints.

NCT ID: NCT04209777 Completed - Smoking Clinical Trials

Clinical Evaluation of Smoker Periodontal Subjects After Lactobacillus-reuteri Probiotics and Antibiotics Therapy

Start date: July 8, 2018
Phase: Phase 3
Study type: Interventional

It is a clinical trial conducted on smokers with chronic periodontitis in which the participants are divided into two groups and one group is provided with antibiotics while the other with probiotics as an adjunct to non-surgical therapy. The participants were assessed for change in probing pocket depths, attachment loss, bleeding on probing, plaque index and gingival index after 1-month and 3-month period.

NCT ID: NCT04178499 Completed - Smoking Clinical Trials

Smoking: Cytokines in Vitreous and Aqueous Humor

Start date: January 1, 2012
Phase:
Study type: Observational

Smoking is a risk factor for ophthalmologic diseases. Inflammation might play a role in their pathogenesis. This study elucidates intraocular cytokine profiles in smokers and non smokers.

NCT ID: NCT04167384 Completed - Smoking Clinical Trials

CSD190301: A Study to Assess Elements of Abuse Liability for Two Dissolvable Nicotine Lozenge Tobacco Products

Start date: December 2, 2019
Phase: N/A
Study type: Interventional

This is a two-arm, single use, single-center, randomized, 10-sequence per arm, open-label, crossover pharmacokinetic/pharmacodynamic (PK/PD) study, designed to evaluate elements of abuse liability (AL) including subjective effects, plasma nicotine uptake, and physiological measures during and following ad libitum use of the study investigational products (IPs) by generally healthy subjects.

NCT ID: NCT04159571 Completed - Smoking Cessation Clinical Trials

QuitFast: Evaluating Transcranial Magnetic Stimulation as a Tool to Reduce Smoking Directly Following a Quit Attempt

Start date: August 20, 2020
Phase: N/A
Study type: Interventional

Cigarette smoking constitutes the greatest preventable cause of mortality and morbidity in the US. The most critical period for long term success of smoking cessation appears to be in the first 7 days after the quit date. A metaanalysis of 3 pharmacotherapy trials revealed that abstinence during the first 7 days was the strongest predictor of 6 month outcomes (n=1649; Odds ratio: 1.4, P <0.0001; Ashare et al. 2013). Prodigious relapse rates during this first week of smoking cessation are likely due to behavioral and neurobiological factors that contribute to high cue-associated craving and low executive control over smoking. The long term goal of the research is to develop evidence-based transcranial magnetic stimulation protocols to facilitate abstinence during this critical period.

NCT ID: NCT04135937 Completed - Smoking Clinical Trials

Mobile Evidence-Based Smoking Cessation for Veterans Living With HIV (MESH)

MESH
Start date: November 18, 2019
Phase: Phase 4
Study type: Interventional

Smoking is a significant cause of damage to health and quality of life specifically for Veterans with human immunodeficiency virus (HIV). Smoking cessation interventions for this population are lacking. The primary aim of this project is to explore smoking cessation treatment preferences among Veteran smokers living with HIV. The study team will refine the design and content of a smoking cessation treatment for Veteran smokers living with HIV. The intervention uses mobile health and telehealth technology to personalize smoking cessation counseling and medications and provide relapse prevention text messaging.

NCT ID: NCT04133376 Completed - Smoking Clinical Trials

Electronic Hookah and Endothelial Cell Function

Start date: November 1, 2019
Phase: N/A
Study type: Interventional

Electronic nicotine delivery systems (ENDS) are a rapidly growing global epidemic among adolescents and young adults. Unlike other ENDS such as e-cigarettes, e-hookahs are used through traditional water-pipes, allowing the vapor-containing nicotine, propylene glycol, glycerin, and flavorings-to pass through a water-filled basin, potentially altering the vapor, before it is inhaled through the user's mouth. Contributing to e-hookahs popularity is the belief that the flavored smoke is detoxified as it passes through the water-filled basin, rendering e-hookah a safer tobacco alternative. However, an e-hookahs deliver flavored nicotine by creating a vapor of fine particles and volatile organic compounds that could induce vascular toxicity. While e-hookah vaping acutely reduces endothelial function, the specific role of nicotine and the mechanisms by which it may impairs endothelial function remain understudied. The objective of this project is to investigate the specific role of nicotine in mediating the acute effects of e-hookah vaping on endothelial dysfunction.

NCT ID: NCT04104152 Completed - Smoking Clinical Trials

CSD190203: A Study to Determine Subject Puffing Patterns of an Electronic Nicotine Delivery System in an Ambulatory Setting

Start date: October 7, 2019
Phase: N/A
Study type: Interventional

This study will be a single-center, randomized, controlled, open-label, parallel 2-cohort study to evaluate the puffing patterns of individuals switching from a similar usual brand (UB) Electronic Nicotine Delivery System (ENDS) product to either a 2.4% or 5% nicotine level ENDS product in healthy adult ENDS users. This study will be conducted for potential submission to the US Food and Drug Administration (FDA) Center for Tobacco Products (CTP) as part of a Premarket Tobacco Product Application (PMTA) for an Electronic Nicotine Delivery System (ENDS), comprised of an electrical power unit and four flavor variants each with two different levels of nicotine (2.4% and 5.0%).

NCT ID: NCT04101422 Completed - Smoking Clinical Trials

Utilizing Augmented Reality as an Adjunct for Smoking Cessation

Start date: October 7, 2019
Phase: N/A
Study type: Interventional

The purpose of the study is to develop an preliminary test a tobacco smoking-related augmented reality (AR) paradigm for eventual development as an adjunctive tobacco cessation intervention.
