Impact of Semaglutide Administration on Tobacco Use Behavior and Related Mechanisms Among Smokers With Obesity
University of Oklahoma
Summary
This pilot randomized trial will assess the impact of 12 weeks of semaglutide administration (vs placebo) on changes in: (i) tobacco use and related factors (nicotine craving, withdrawal, motivation to quit, etc.) and (ii) biological biomarkers of health (e.g., epigenetics, glucose variability via continuous glucose monitoring \[CGM\], etc.) in adult smokers with obesity (n = 40). We will integrate molecular biology procedures (e.g., epigenetics) to maximize internal validity with real-world smartphone-based ecological momentary assessment (EMA) surveys to maximize external validity
