Weight Loss and Nausea from Subcutaneous and Oral Semaglutide Accurately Simulated with a QSP Model

Conference: ACoP

The availability of effective GLP-1 receptor agonists (GLP-1RAs) for obesity treatment has greatly benefited patients. Balancing body weight (BW) loss with nausea is crucial to predict the effectiveness of these medications, along with understanding the impact of delivery methods. Quantitative Systems Pharmacology (QSP) modeling helps predict efficacy and adverse events, assessing key differences and similarities between treatment protocols.
