Agonista del receptor del péptido 1 similar al glucagón en el tratamiento del asma sintomática relacionada con la obesidad en adultos (GATA-3) (GATA-3)

30 de septiembre de 2026 actualizado por: Katherine Cahill, MD, Vanderbilt University Medical Center

Tratamiento con agonistas del receptor del péptido 1 similar al glucagón en adultos con asma sintomática relacionada con la obesidad (GATA-3)

This is a randomized placebo-controlled trial of semaglutide, an FDA-approved therapy for the treatment of type 2 diabetes mellitus and obesity, in adults with symptomatic asthma despite the use of inhaled steroids and with excess body weight. This study will test the central hypothesis that semaglutide will improve asthma control and reduce airway inflammation due to direct effects on the respiratory tract in adult asthma associated with obesity.

Descripción detallada

This is a proof-of-principal randomized, double-blind, placebo-controlled, single-site clinical trial of semaglutide in adult (age 18 or older, n=100), obesity-related (BMI≥30), symptomatic asthma without type II diabetes. This study will monitor clinical asthma symptom and quality of life questionnaires and airway function to determine the effect of semaglutide on asthma control. Markers of respiratory tract and adipose tissue inflammation will be monitored to determine the effect of semaglutide on airway inflammation. Study participants will be monitored for 4 weeks before assignment to treatment with the study drug for 24 weeks followed by a 2 week final monitoring period.
