1,222 Clinical Trials for Various Conditions
This study will be an online survey experiment conducted with adults who smoke cigarettes (ages 21+) to examine their reactions to modified risk advertising claims authorized by the Food \& Drug Administration (FDA) for two smokeless tobacco brands (General Snus and Copenhagen), which describe the lower risks of these products compared to cigarette smoking. The study will compare effects of ads with different two different claim types (i.e. claims about reduced lung cancer risk and claims about reduced risks for multiple disease) versus ads with no reduced-risk claims, and examine effects on message and product perceptions, and interest in using the smokeless tobacco products. This study will also examine how smokers' reactions/interest may vary based on the product brand, and asses prior awareness/exposure to the authorized claims.
In a within-subject design, investigators will use the Experimental Tobacco Marketplace (ETM) to systematically impose 4 novel tobacco/nicotine tax proposals (Tobacco Parity, Nicotine-Content, Harm-Reduction, and Modified Risk Tobacco Product-related taxes) covering a broad range of tax magnitudes. Participants will complete one control trial and all conditions (tax proposals) in the ETM with 5 trials each. Analyses will model the quantity of the product purchased as a function of tax tier (i.e., high, medium, no tax) and examine poly-tobacco purchasing.
The purpose of this study was to obtain information on nicotine exposure following the use of five oral tobacco-derived nicotine (OTDN) products relative to subjects' own brand moist smokeless tobacco (OBMST) product in adult moist smokeless tobacco (MST) users, as well as to characterize subjective effects under controlled use conditions. Male and female adult MST users between the ages of 22 to 65 years were recruited. The total duration of participation for each subject was approximately 34 days including screening and a 6-day in-clinic study confinement period.
This clinical trial evaluates the effect of message framing on smoking behaviors among lesbian, gay, bisexual, transgender, queer (LGBTQ+) young adults who use nicotine and/or tobacco. Tobacco regulation has contributed to a steady decline in tobacco products designed to be smoked (combustible), but there has been an increase in the use of new tobacco products, such as electronic nicotine delivery systems (ENDS). The use of more than one tobacco product (polytobacco) is high in LGBTQ+ populations. Both LGBTQ+ people and people who engage in polytobacco use are less likely to view tobacco as harmful, which may reinforce tobacco use. Message framing includes culturally targeted messages to communicate the absolute risks (AR) and relative risks (RR) of polytobacco use. Using message framing may increase quit rates or change smoking behaviors in LGBTQ+ young adults who use nicotine and/or tobacco products.
This study is designed to assess and characterize levels of selected harmful and potentially harmful constituents (HPHCs) and other endpoints of interest in an environmental chamber (EC) after ad libitum use of Ploom® heated tobacco product (HTP) and combustible cigarettes (CC) in their respective group (menthol and non-menthol smokers) by adults who smoke (AS).
The goal of this pilot project is to explore the feasibility of a real-world marketplace study design examining the effects of a reduced nicotine product standard for cigarettes on smoking in the context of a flavor restriction vs. no restriction on e-cigarettes in smokers switched to very low nicotine content cigarettes.
This is a randomized, controlled, six-way crossover clinical study to characterize the nicotine PK (pharmacokinetic) and subjective effects of HTPs (Heated Tobacco Products) comprised of 2 menthol varieties and 2 tobacco flavor varieties (Ploom® HTPs, Japan Tobacco Inc.) in adult menthol and non-menthol combustible cigarette smokers (males and females between the ages of 22 and 65). The study will include participants' UBCC (Usual Brand Combustible Cigarette) and a nicotine gum (Nicorette®) as high and low abuse liability reference products, respectively, to the HTP. Study participation is expected to last up to 34 days, including a 28-day screening period (that includes a 5-day at-home HTP product trial period), and a 6-day in-clinic confinement period (from Check-in \[Day -1\] through the end-of-study \[EOS\] visit on Day 6).
The purpose of the study is to evaluate changes in biomarkers of exposure (BoE) to harmful and potentially harmful constituents (HPHCs) in adult smokers who completely switch to Ploom heated tobacco products (HTPs) compared to those who continue to smoke usual brand combustible cigarettes (UBCC).
The proposed study is a randomized clinical trial. The overarching goal of the study is to apply Community Based Participatory Research (CBPR) to reduce tobacco use among youth and young adults (14-21 y/o) in Baltimore City through a mixed-method approach adapted to the needs of youth and young adults. This study has partnered with the American Lung Association's Not On Tobacco (N-O-T) program and aims to deliver tobacco cessation classes. The study will target Baltimore City high schools and colleges, prioritizing facilities in underserved inner-city communities. The proposed research consists of a 2-arm trial where participants from four high schools and two colleges will be randomized to peer-facilitated tobacco cessation classes or self-navigated groups. The trial aims to assess the effectiveness of peer-facilitated tobacco cessation intervention compared to self-navigated tobacco cessation in terms of their success rates (quitting and staying quit). The study's primary hypothesis is that the tobacco cessation rate will be equal to or higher in the peer-facilitated arm than in the self-navigated arms. The secondary hypothesis is that the retention rate will be equal to or higher in the peer-facilitated arm compared to the self-navigated arm. CEASE Youth tobacco cessation program is an eight-week program based on the American Lung Association's (ALA) Not On Tobacco (N-O-T) program. The ALA's N-OT program is acknowledged as an accessible and effective option for teen tobacco cessation. Participants in the peer-facilitated group will be given the evidence-based N-O-T program curriculum and provided with virtual materials, information, and resources by their assigned peer facilitators. Virtual tobacco cessation peer motivation sessions will be offered using the digital online platform Zoom, and the peer facilitators will communicate with the participants in between the classes. The participants in the self-navigated group will receive the same ALA N-O-T program curriculum and complete the eight-week sessions, but it will be self-navigated and without peer facilitations. No peer facilitator will be assigned to this group, and the participants will complete the curriculum by themselves. They will also receive other available resources, including information about the local tobacco cessation services available.
The overall aim of this research is to experimentally evaluate the extent to which partially standardizing the color of tobacco packaging influences tobacco use intentions among young adults who have varying levels of tobacco use experience.
The investigators will conduct a message-exposure experiment with nationally representative samples of smokers, dual-users (cigarettes and e-cigarettes), and young adult non-smokers (aged 18-29). Experimental messages will address the reduction of nicotine in cigarettes. Participants will also complete a follow-up survey after 2 weeks, measuring their recall of the messages and behaviors since message exposure.
This project examines the influence of flavor availability on switching to an MRTP known as IQOS, part of the Heated Tobacco Product (HTP) class, among menthol smokers using clinical lab and naturalistic evaluations of abuse liability. Results will help federal regulators predict the public health impact on menthol cigarette smokers of policies restricting access to menthol-flavored HTPs.
The purpose of the study is to evaluate how limiting the nicotine content in regular cigarettes affects choices for regular cigarette and e-cigarette products. Eligible participants will be of legal age to purchase tobacco products and regularly use both e-cigarettes and regular cigarettes.
This is a single-center, open-label, parallel-cohort study to measure and compare the levels of selected secondhand smoke (SHS) constituents of a heated tobacco product (HTP) against combustible cigarettes (CC) after ad libitum smoking sessions by generally healthy smokers in an environmental testing chamber (ETC). Evaluation of SHS constituents detected during non-smoking sessions will be performed as a control.
This is a multi-center, open-label, parallel-cohort-study to evaluate the puffing patterns of healthy adult consumers of tobacco products switching from a usual brand (UB) combustible cigarette (CC) and/or a UB Heated Tobacco Product (HTP) to one of four investigational products (IPs), across two heating modes, over a 28-day ambulatory period.
The purpose of this research study is to find out how three different nicotine pouches and participant's own brand of smokeless tobacco affect blood nicotine levels and how participants feel.
This study will investigate the relative appeal (abuse liability) of novel tobacco products, how the appeal is modulated by relative price, user type, and how novel products may substitute for one another.
This is a randomized, controlled, multi-center, open-label, 8-cohort parallel group study to assess changes in select biomarkers of exposure (BoE) and biomarkers of potential harm (BoPH) in generally healthy smokers switching to the study investigational products (IPs), compared to subjects who continue to smoke, undergo smoking abstinence, or have never smoked.
This is a single-center, open-label, randomized, 2-arm, within-arm cross-over study designed to evaluate elements of abuse liability (AL) including subjective effects and physiological measures (pharmacodynamics \[PD\]), and plasma nicotine uptake (pharmacokinetics \[PK\]) during and following ad libitum use of the study investigational products (IPs) by generally healthy smokers.
This is a multi-site, open-label, 8-week, prospective observational study, conducted at multiple sites geographically dispersed within the U.S. The purpose of this Actual Use Study (AUS) is to investigate how U.S. adult tobacco consumers 21 to 60 years of age, inclusive, who typically smoke on average (≥5 cigarettes/day) on at least 20 out of the past 30 days will use a heated tobacco product comprising a heating device and four non-combusted cigarette variants (HTP Investigational Product \[IP\]) over a 6-week Actual Use Period (AUP) in their real-life/naturalistic environment and in the context of typical consumer marketing materials.
To pilot test the appeal of non-tobacco oral nicotine products in cigarette smokers, smokeless tobacco users, and oral nicotine users.
The purpose of this study is to evaluate the effect of various tobacco products (including but not limited to combustible cigarettes, medicinal nicotine, electronic cigarettes, and smokeless tobacco) on cutaneous wound healing. There will also be a non- smoking control group. This study will be designed as a pilot study. The majority of individuals will be recruited from ongoing studies at the University of Minnesota - Tobacco Research Programs.
A novel heat-not-burn tobacco product (IQOS) will be provided to smokers, compared against a (cigarette) smoking as usual period in counter-balanced order in a cross-over design. This study will examine the short-term effects of IQOS, switching from combustible to noncombustible nicotine and withdrawal-related symptoms over a two week-long "practice" period, relative to smoking as usual.
This is a single site, open-label, randomized, cross-over study designed to evaluate elements of abuse liability (AL) including subjective effects and physiological measures (pharmacodynamics \[PD\]) and plasma nicotine uptake (pharmacokinetics \[PK\]) during and following ad libitum use of the study investigational products (IPs) by generally healthy subjects.
A novel type of non-cigarette tobacco product was recently approved for sale in the US, the heated tobacco product (HTP) IQOS. IQOS may be less harmful than cigarettes, and there are some reports that it may produce more rewarding subjective effects compared to e-cigarettes. The approval of IQOS provides a unique opportunity to gather preliminary data surrounding IQOS. The goal of this pilot study is to assess the subjective effects and relative reinforcement value of IQOS, including its downstream effects on cigarette smoking. Current smokers will complete a one-week baseline period where they smoke as normal before attending an in-person lab visit. During the in-person lab visit, participants (n=10) will sample a traditional cigarette and a novel IQOS tobacco product. Participants will answer questionnaires about each product they sample and then complete a preference assessment in which they choose between the IQOS and their own cigarette. Finally, participants will take home a tobacco product they sampled to use ad libitum (1-week sampling). During the at-home baseline and sampling weeks, participants will complete electronic daily diaries cataloging their tobacco use. Biomarkers (i.e., expired carbon monoxide, cotinine) will corroborate self-reported indices of use.
This is a multicenter, post market surveillance study designed to evaluate biomarkers of tobacco exposure and effect, health status measurements, and tobacco product usage patterns in subjects who are natural adopters of cigarettes and/or smokeless tobacco. Non tobacco users will serve as a non use comparison group. This study is unblinded by necessity due to the very different visual appearance of the subject's Usual Brand (UB) of tobacco product(s).
This trial studies activity of time (pharmacokinetics), subjective effects, and abuse liability of nicotine salt-based vaping products with tobacco or e-liquids. This study aims to determine and compare the levels of nicotine delivered to the bloodstream from nicotine salt and free-base nicotine e-liquid solutions.
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.
The purpose of this study was to estimate changes in biomarkers of exposure (BOE) in adult cigarette smokers using an oral tobacco-derived nicotine (OTDN) product relative to adult smokers who continue smoking exclusively.
The purpose of this study is to compare plasma nicotine uptake in adult snus consumers after using investigational snus products (A19010-W and B19010-F).
