Filter by:This is a randomized, controlled, open-label, 4 parallel arm study with a stratified randomization by sex (a quota for each sex [females and males] of at least 40% overall). This study aims to demonstrate the reduction of Biomarkers of Exposure (BoExp) to selected Harmful and Potentially Harmful Constituents (HPHC) in smokers switching from cigarettes (CIG) to each of the Tobacco Heating System (THS) variants with different heating technology (Blade device, Induction Mono device, or Induction Mid device, respectively), compared with smokers who continue to smoke CIG. A reduction of exposure to HPHC is expected in CIG smokers when switching completely to THS.
Tobacco use is a risk factor for at least 20 types of cancer and remains the leading preventable cause of cancer in Canada. Smoking cessation is an important cancer prevention strategy for the close to 2 million Canadian women who currently smoke. However, findings from controlled trials and real-world clinical settings indicate that women have greater difficulty achieving abstinence following a quit attempt than men. There is some evidence that hormonal levels and fluctuations throughout the menstrual cycle (MC) may contribute to the greater difficulty women experience when trying to quit smoking. In this study, the start of a quit attempt using nicotine replacement therapy (NRT) will be targeted to specific phases of MC. It was hypothesized that starting a quit attempt during the first half of MC (follicular phase) will result in increased quit success compared to starting during the second half of MC (luteal phase) or the usual practice of not targeting quit start date to MC phase.
This study is for people with chronic obstructive pulmonary disease (COPD) and who smoke. Investigators are trying to find out if training on e-cigarette use will help smokers switch to e-cigarettes. If training helps, how much training is needed for people to fully switch from cigarettes to e-cigarettes?
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.
The objective of this study was to conduct a pilot factorial randomized trial to identify the message frames that are most effective in promoting participation in a tobacco treatment trial for current smokers recently diagnosed with cancer. To do so, we used a multimethod approach to evaluate 3 different message frames across evaluation, effectiveness, and outcome measures. We combine findings from a message design experiment with textual analytic software to provide a holistic understanding of how message frames may or may not differentially affect tobacco treatment trial participation within the context of a cancer diagnosis.
Cannabidiol is a compound found in cannabis plants that is well tolerated, has low abuse liability, and might be an effective medication to promote tobacco cessation. This clinical study will use a validated approach for screening tobacco cessation medications to determine if oral cannabidiol increases short-term tobacco abstinence, and evaluate mechanisms that might explain how cannabidiol alters smoking behavior. Results from this study will provide data on the therapeutic potential of cannabidiol for tobacco cessation.
Although many women initially quit smoking during pregnancy, most will return to smoking by the end of pregnancy or during the first 6 months postpartum. The proposed pilot project is designed to evaluate the feasibility and potential efficacy of offering small financial incentives for the completion of smoking cessation coaching and biochemically-verified smoking abstinence at follow-up among pregnant women with Medicaid insurance who contact the Oklahoma Tobacco Helpline (OTH). The study will enroll 100 pregnant women who will be randomly assigned to OTH care or OTH plus escalating incentives (OTH+I) for completing up to 5 coaching calls over the first 8 weeks after enrolling (prepartum) and for biochemically-verified smoking abstinence at 9 weeks post-enrollment (assessed remotely via smartphone). In addition, participants will be incentivized for completing a postpartum coaching call by 8 weeks postpartum. Feasibility outcomes for the incentives based intervention will focus on coaching call completion, rates of prepartum and postpartum follow-up, biochemically-verified smoking cessation, and perceptions of the intervention. Potential effectiveness will be evaluated by comparing biochemically-verified smoking abstinence rates in OTH+I relative to OTH alone at 12 weeks post-enrollment (prepartum) and 12 weeks postpartum.
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.
The objectives of this project are to develop, implement, and test the feasibility and effectiveness of an artificial intelligence adaptive mobile pregnancy tobacco cessation app-based intervention using deep tailoring and a self-nominated support person, and to build mHealth research capacity in Romania. The central hypothesis is that the intervention will show evidence of feasibility and effectiveness in increasing positive support, pregnancy cessation, and postnatal abstinence. The intervention is grounded in Self-Determination Theory (SDT) and Motivational Interviewing (MI), a counselling style that is effective in assisting people to quit smoking. The app will be novel in its use of the unique functionality of smartphones, use of reinforcement learning (RL) and deep tailoring to continuously adapt the intervention, the emphasis on increasing positive support, and the use of the app by both smoker and support person. The long-term goal of the research program is to use mHealth for smoking cessation leveraging the unique functionality of smartphones and to continue building mHealth research capacity and developing research networks in Central and Eastern Europe (CEE) and other LMICs. Aim 1 (R21 phase). Develop and test the feasibility and acceptability of the SFT2.0 app-based mobile smoking cessation intervention with a support person during pregnancy and postpartum in Romania. Through a user-centered and iterative design the investigators will enhance the SFT1.0 app, deepen the tailoring, incorporate RL, expand the app for use by any support person, and test the intervention including the app and MI video counseling in a series of usability studies and a 12-week open trial (n=20). Aim 2 (R33 phase). Test the SFT2.0 app-based smoking cessation intervention in a hybrid effectiveness and implementation randomized controlled trial. The investigators will randomize 375 pregnant smokers and their support persons to i) a fixed arm, including the SFT2.0 app for both, and fixed pre- and postnatal MI counseling; ii) an RL-adaptive arm, with the app continuously optimizing as-needed MI counseling; or iii) control group. Aim 3 (R21 and R33 phases). Develop mHealth research capacity by enhancing individual and institutional research capabilities in Romania and expanding the existing international research network.
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.
