Filter by:Smoking accounts for approximately 30% of total cancer deaths each year. Even though former studies show that persons with a cancer diagnosis are less likely to smoke than the general population up to 50% of people who smoke and have lung cancer do not stop smoking after their diagnosis or frequently relapse after smoking cessation. Continued smoking leads to increased all-cause mortality, increased cancer-specific mortality, and decreased quality of life. It is well-known that cancer patients are interested in smoking cessation therefore smoking cessation interventions play an important role in the management of people with cancer. This study will evaluate the effectiveness of an intensive smoking cessation interventions on cancer patients in real life. The project provides new knowledge about smokers diagnosed with cancer.
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.
An Open-Label, Multi-Center Study to Evaluate Selected Constituents in the Exhaled Breath Samples From the Use of JUUL Nicotine Salt Pod System Product (5% and 3% Virginia Tobacco, Mint, Mango, Menthol) Users and Conventional Cigarettes (Non-Menthol and Menthol Flavors)
The purpose of this study is to estimate nicotine uptake and assess subjective effects during ad libitum use sessions of 4 flavors of JUUL ENDS (also referred to as nicotine salt pod system; NSPS) products (i.e., Virginia Tobacco, Mint, Menthol and Mango) with 2 different nicotine concentrations. Subjective effects will also be assessed to gain an understanding of the user's experience during and after JUUL ENDS product use to evaluate the abuse liability of the products. The subject population will consist of healthy adult, male and female smokers, 21 to 65 years of age.
A Randomized, Open Label, Parallel Group Study in Adult Smokers to Evaluate Changes in Biomarkers of Cigarette Smoke Exposure After Switching Either Exclusively or Partly to using JUUL Electronic Nicotine Delivery Systems With Two Different Nicotine Concentrations
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%).
This is a randomized, open-label, crossover 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 investigational products (IPs) by healthy subjects.
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 is an observational, crossover design that will examine the pharmacokinetics and pharmacodynamics of impact of smoking tobacco cigarettes or vaping the JUUL electronic cigarette.
Open trial of heart rate variability biofeedback as an adjunct to individualized smoking cessation counseling (SCT) plus transdermal nicotine replacement patch (NRT) in smokers with elevated emotional distress.
