成人、肥満関連、症候性喘息(GATA-3)の治療におけるグルカゴン様ペプチド-1受容体アゴニスト (GATA-3)

2026年9月30日 更新者:Katherine Cahill, MD、Vanderbilt University Medical Center

成人、肥満関連、症候性喘息(GATA-3)におけるグルカゴン様ペプチド-1受容体アゴニスト治療

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.

条件

詳細な説明

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.

      #Use of any inhalant >1 time weekly in the past year is considered use within 12 months.

    • Active smoking of conventional tobacco, inhaling of marijuana or other drugs, or vaping of e-cigarettes or vape pods >1 time per week in the past year.

    • Any form of tobacco qualifies, such as: 1 cigarette, 1 hookah or shisha sessions, 1 cigar, 1 pipe, etc.

    • Any electronic (e)-device included: e-cigarette e-cig, mod, vape pen, JUUL, e-cigar, e-hookah, e-pipe, vape pods, etc.

    • Any form of inhaled marijuana, including smoking marijuana leaves or inhaling THC via e-cigarette or device

  6. Pregnancy by urine testing, current lactation, or plans to become pregnant during the study period

  7. Pharmaceutical weight loss treatment for >7 days in the prior 90 days at enrollment

  9. Personal history of pancreatitis as determined by history

  10. Personal or family history of medullary thyroid cancer by history or multiple endocrine neoplasia syndrome type 2

  14. Personal history of hypersensitivity to local amide type (ex. Lidocaine) anesthetics

  15. Use of antidiabetic agent, other than metformin, including GLP-1R agonist in the previous 90 days. Metformin is allowed provided the dose has been stable in the 90 days prior to screening and will remain stable for the duration of the trial.

  16. Use of systemic glucocorticoids in the past 28 days

  17. Use of monoclonal antibody for the treatment of asthma in the past 120 days

  18. Myocardial infarction, unstable angina, stroke, or heart failure (NYHA class II) within 1 year by history

  19. Patient report and confirmed by review of historical diagnostic testing by study physician of other physician-diagnosed chronic respiratory diseases: COPD, cystic fibrosis, pulmonary hypertension, interstitial lung disease, sarcoidosis, bronchiectasis

  20. History of physician-diagnosed immune deficiency.

  21. History of physician-diagnosed malignancy (other than excised non-melanoma skin cancer) in the past 5 years.

  22. Current uncontrolled hypertension (systolic >150, diastolic >90) or untreated hyperthyroidism

  23. Current, diagnosed or self-reported drug or alcohol abuse that, in the opinion of the investigator, would interfere with the subject's ability to comply with study requirements.

  24. Use of investigational drugs within 20 weeks of participation, other than vaccines and/or treatments for SARS-CoV-2 authorized for emergency use
