    GLUCOSE-MGH: Genetic Links Understood Through Challenge With Oral Semaglutide Exposure at MGH

    Testing how genetics affect the body’s blood sugar response to oral semaglutide in type 2 diabetes

    📍 Massachusetts General Hospital · Boston, MA · Get directions →

    The goal of this research study is to evaluate the pathophysiologic mechanisms by which genetic variation impacts response to an FDA-approved medication commonly used to treat type 2 diabetes called oral semaglutide (Rybelsus) and to characterize the physiological response to a mixed meal tolerance test (MMTT) before and after a 14-day treatment with oral semaglutide. The investigators will do this by measuring factors in the blood, such as sugars, fats, metabolites, and proteins, after eating a standardized breakfast meal at the first visit and after taking 14 doses of oral semaglutide over two weeks before the second study visit.
