Tobacco clinical trials at UCSF
8 in progress, 3 open to new patients

  • Cardiovascular Assessment of the Effects of Tobacco and Nicotine Delivery Products

    open to eligible people ages 18–50

    The overarching goal of this project is to develop a panel of cardiovascular risk biomarkers that can detect differences in the cardiovascular safety of various tobacco products, whether conventional, new or emerging, in order to help the FDA with the task of regulating them. This will be achieved through 4 aims: Aim 1: Determine the relative contributions of nicotine and combustion products to the cardiovascular risk of active cigarette smoking. Aim 2: Determine which cardiovascular risk biomarkers are affected by exposure to secondhand smoke. Aim 3: Determine the cardiovascular risk of smokeless tobacco use. Aim 4: Determine the cardiovascular risk of electronic cigarettes and the respective contributions of nicotine and electronic cigarette vapor.

  • Secondhand Smoke Respiratory Health Study

    open to eligible females ages 40–80

    Exposure to secondhand tobacco smoke (SHS) is associated with diverse health effects in nonsmokers. Flight attendants who worked on commercial aircraft before the ban on tobacco smoking (exposed FAs) had high, long-term levels of occupational exposure to SHS and are a unique population for the study of long-term health effects of chronic exposure to SHS. In previous studies, we have shown that many never-smoking SHS-exposed FAs to have curvilinear flow-volume loops, decreased airflow at mid- and low-lung volumes, and static air trapping (elevated residual volume to total lung capacity ratio [RV/TLC]), abnormalities that are not diagnostic of overt COPD, but do implicate the presence of an obstructive ventilatory defect, and are consistent with what has been recently described as preserved ratio impaired spirometry (PRISm). The main objective of the study is to determine the effect of a bronchodilator to counter the physiologic abnormalities that are observed in the population of never-smoking SHS-exposed FAs as both proof of concept of the presence of an obstructive lung disease and as a possible therapeutic option to counteract the adverse respiratory effects of chronic exposure to SHS.

  • Smoking Tobacco and Drinking Study

    open to eligible people ages 18–25

    This trial will test the efficacy of a 3-month intervention on Facebook targeting tobacco use and heavy episodic drinking against a 3-month Facebook intervention targeting tobacco use. Both groups will be offered a nicotine patch starter kit. The primary outcome is verified 7-day point prevalence abstinence from smoking at 3, 6, and 12 months.

  • A Facebook Intervention for Young Sexual and Gender Minority Smokers

    Sorry, not yet accepting patients

    The 2-year research plan will test the Put It Out Project (POP) in a pilot randomized trial (N=120) compared to TSP and two historical control conditions. Participants will be young adults who smoke, identify as sexual or gender minorities, and use Facebook. The primary outcome will be biochemically verified 7-day abstinence from smoking at 3 and 6 months. Secondary outcomes will be a quit attempt (y/n), stage of change, and thoughts about tobacco abstinence at 3 and 6 mos.

  • Impact of Very Low Nicotine Content Cigarettes in a Complex Marketplace

    Sorry, not yet accepting patients

    This project will examine the impact of very low nicotine content (VLNC) cigarettes in a complex tobacco and nicotine product marketplace. We will compare the number of cigarettes smoked, use of alternative nicotine-containing products, biomarkers of toxicant exposure and days abstinence from cigarettes in an experimental marketplace that contains VLNC cigarettes versus normal nicotine content (NNC) cigarettes.

  • Mobile-based Peer Mentoring for Smoking Cessation

    Sorry, not yet accepting patients

    Despite the availability of a variety of effective treatments for smoking cessation, uptake of treatments is low. The increasing use of smartphone technology presents an exceptional opportunity to expand access to low-cost smoking cessation services. In this pilot study, the investigators will use a text-messaging platform to test peer mentoring for smoking cessation, delivered by former smokers. While peer mentoring is a common approach to health behavior change, it has rarely been used to maximum effect by smoking cessation programs. The text-messaging platform serves as the basis for a randomized controlled trial to test the effectiveness of peer mentoring for smoking cessation. This pilot will include approximately 200 U.S. adult smokers who will be randomly assigned to a peer mentor or not. Participants in the control group will receive automated text messages used in SmokefreeTXT, a nationwide text-messaging service sponsored by the National Cancer Institute (NCI) in which users receive one to five automated messages per day for up to eight weeks. Smokers in the intervention group will receive a modified version of the same automated messages from SmokefreeTXT, but with additional personalized messages from an assigned peer mentor. Mentors will provide responses to specific questions or comments a smoker may have after receiving the automated messages. The intervention will last 8 weeks. The study includes primary outcomes to measure the acceptability, engagement, user experience, and early efficacy of the intervention.

  • Healing and Empowering Alaskan Lives Towards Healthy-Hearts Study

    Sorry, not currently recruiting here

    This study aims to identify effective and cost-effective interventions for tobacco use and other risk behaviors for cardiovascular disease among Alaska Native people in rural villages. In a randomized controlled trial, the study will compare interventions using telemedicine to promote the American Heart Association's identified ideal health behaviors (nonsmoking and physical activity) relative to ideal health factors (managing cholesterol and blood pressure).

  • Project 2: Strategies for Reducing Nicotine Content in Cigarettes

    Sorry, in progress, not accepting new patients

    The main goal of this project is to compare two different approaches to reducing levels of nicotine in cigarettes: an immediate reduction in nicotine content in cigarettes to non-addictive levels or a gradual reduction in nicotine content in cigarettes to non-addictive levels. These two approaches will then be contrasted to a group that continues to smoke cigarettes with nicotine content similar to conventional cigarettes.
