Imaging changes in muscle with semaglutide for type 2 diabetes and obesity

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study will track adults aged 45-75 with BMI ≥30 kg/m2 and T2D who begin subcutaneous semaglutide. Participants will have MRI to measure muscle volume and quality, and 31P-MRS to assess muscle metabolism, at baseline, 3 months, and 6 months. The study will compare imaging findings with changes in BMI and patient-reported outcomes to explore longitudinal muscle effects during semaglutide therapy. The goal is to understand whether weight loss from treatment is associated with preserving or altering skeletal muscle characteristics.

5. History of myocardial infarction or coronary revascularization (percutaneous intervention or coronary artery bypass) within 30 days prior to screening.
6. History of hospitalization for heart failure within the past 30 days, or NYHA class IV
7. Current use of glucocorticoid therapy (≥5 mg prednisone or equivalent).
8. Self-reported weight loss \> 10 lbs in the 90 days prior to screening.

11. Glomerular Filtration Rate (eGFR) within the past 120 days is not available.
12. Mental incapacity or language barriers preventing informed consent and compliance.
13. Pregnancy, plans for pregnancy in the next 12 months, or lactating/nursing females.
