Clinical Trial Summary

Atrial fibrillation (AF) is the most common arrhythmia worldwide. AF is associated with obesity and the co-morbidities of obesity, including hypertension and obstructive sleep apnea (OSA) which increase left atrial (LA) size and decrease LA function. Semaglutide, a Glucagon-like peptide receptor 1 agonist (GLP-1 RA), is currently approved by the Food and Drug Administration for weight loss for individuals with and without diabetes. The effects of pharmacologic weight loss with Semaglutide on AF are unknown. The investigators plan on conducting a randomized controlled trial of semaglutide versus placebo in individuals with paroxysmal or early persistent AF (>10% AF burden on ambulatory monitoring, a previous electrical cardioversion, or AF lasting ≥ 7 days but < 3 months who have a body mass index ≥ 27.0 kg/m2. The trial will last for 52 weeks. The primary outcome will be the change in AF burden for 2 weeks, immediately before starting the medication or placebo to two weeks starting at week 50, as determined by an implantable loop recorder or two week ambulatory Additional outcomes will be change in epicardial adipose tissue as determined by chest/abdomen/pelvis computed tomography scan at enrollment and at week 52, change in apnea-hypopnea index from baseline sleep study to week 52 sleep study, change in LA longitudinal strain from baseline echocardiogram to echocardiogram at 52 weeks, and change on symptom surveys.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Atrial fibrillation burden	Change in AF burden from the two weeks before starting Semaglutide or placebo to the last two weeks of therapy (starting at week 50). AF burden will be assessed as percent of time in AF for two weeks on an implantable loop recorder. If the patient declines implantable loop recorder placement, an ambulatory 2-week monitor will be used instead.	52 weeks
Secondary	Epicardial adipose tissue	Change in epicardial adipose tissue on non-contrast chest/abdomen CT scans from baseline and week 52	52 weeks
Secondary	Sleep apnea	Change in apnea-hypopnea index from baseline sleep study to sleep study at week 52	52 weeks
Secondary	Left atrial function	The change in LA longitudinal strain from the baseline echocardiogram to the echocardiogram at 52 weeks.	52 weeks
Secondary	Weight change	From baseline to week 52	52 weeks
Secondary	Adherence and Adverse Events	From baseline to week 52	52 weeks
Secondary	Participation in VA MOVE	assess participation	52 weeks
Secondary	Change in AF burden for four weeks	Change in AF burden for 4 weeks before starting the medication to weeks 48-52.	52 weeks
Secondary	Fat depots	change in pericardial, abdominal (visceral and subcutaneous) and hepatic adipose tissue	52 weeks
Secondary	Left atrial size and function	Changes in LA size and function between baseline and week 52 echocardiograms: LA volume as assessed using the biplane disk summation method, LA reservoir strain, LA conduit strain, and LA booster pump strain will be assessed as secondary outcomes	52 weeks
Secondary	Quality of life on Healthcare Quality of Life surverys	Quality of life on the Short-Form 36 survey and the AF symptoms and severity checklist, which will be completed at baseline and at week 52	52 weeks
Secondary	Change in C-reactive Protein (CRP)	Change in the biomarker CRP between baseline and week 52	52 weeks
Secondary	Blood pressure	Changes in blood pressure and blood pressure medication use between baseline and week 52 will be assessed at those visits.	52 weeks
Secondary	Change in Interleukin-6 (IL-6)	Change in the biomarker IL- 6 between baseline and week 52	52 weeks
