Intervention model description: Investigator-driven, prospective, parallel-group, double-blind, randomized controlled clinical trial
Primary purpose: TREATMENT

Brief summary: The purpose of this pilot study is to assess the feasibility of a double-blind, randomized placebo-controlled trial of semaglutide 2.4 mg subcutaneously once weekly on top of standard care compared to standard care alone.

Detailed description: The SOCRATES-AF pilot study is a prospective, parallel-group, double-blind, randomized controlled trial in patients with paroxysmal or early persistent atrial fibrillation and overweight and obesity.

The primary objective is to assess the feasibility of a double-blind, randomized placebo-controlled trial of semaglutide 2.4 mg subcutaneously (s.c.) once weekly on top of current standard care (lifestyle and risk factor management, oral anticoagulant and rate control therapy) versus current standard care alone in overweight or obese patients with symptomatic paroxysmal or early persistent AF.

To assess recurrences of atrial fibrillation all participants will receive an implantable cardiac monitor.

Eligibility criteria: Inclusion Criteria:

* Signed informed consent before any study-related activity
* ≥ 18 years of age at the time of signing informed consent
* Body mass index (BMI) ≥ 30 kg/m2
* Body mass index (BMI) ≥ 27 kg/m2 and at least 1 concomitant cardiometabolic risk factor (hypertension, dyslipidemia, or obstructive sleep apnea)
* Symptomatic paroxysmal or early persistent atrial fibrillation (Paroxysmal AF: Self- terminating, in most cases within 48 hours up to 7 days. AF episodes that are cardioverted within 7 days with a documented 12 lead ECG showing sinus rhythm within the last 12 months; early persistent AF: AF episodes lasting longer than 7 days, including episodes that are terminated by cardioversion, either with drugs or by direct current cardioversion, after 7 days or more. Early persistent AF in this trial is defined as persistent AF with first-time electrical cardioversion (ECV) or a maximum of 1 previous ECVs.)

Exclusion Criteria:

* General exclusion criteria

  * Age ≥75 years
  * History of type 1 or 2 diabetes (history of gestational diabetes is allowed)
  * Known or suspected hypersensitivity to study medication or related products
  * Treatment with GLP-1 receptor agonists within the last 3 months before randomisation
  * Treatment with dipeptidyl peptidase-4 (DPP-4) inhibitors
  * Alcohol/drug abuse
  * Pregnant or breastfeeding women
  * Fertile women not using chemical (tablet/pill, depot injection of progesterone, sub- dermal gestagen implantation, hormonal vaginal ring or transdermal hormonal patch) or mechanical (spirals) contraceptives

  * Acute or chronic pancreatitis
  * Obesity induced by other endocrinologic disorders (e.g. Cushing's Syndrome)
  * Current history of treatment with medications that may cause significant weight gain, within the last 3 months before screening, including systemic corticosteroids (except for a short course of treatment, i.e. 7-10 days), tri-cyclic antidepressants, atypical antipsychotic and mood stabilizers (e.g. imipramine, amitriptyline, mirtazapine, paroxetine, phenelzine, chlorpromazine, thioridazine, clozapine, olanzapine, valproic acid and its derivatives, and lithium)
  * Diet attempts using herbal supplements or over-the-counter medications within 3 months before screening
  * Current participation (or within the last 3 months) in an organised weight reduction programme or currently using or used within 3 months before screening: pramlintide, sibutramine, orlistat, zonisamide, topiramate, phentermine (either by prescription or as part of a clinical trial)

  * Hospitalization due to decompensated heart disease within 30 days prior to randomization
  * Congestive heart failure (NYHA class IV)
  * Current myocardial or pericardial infection
  * Permanent pacemaker (PM) in use or implantable cardioverter defibrillator (ICD)
  * Patient cannot be prescribed non-vitamin K oral anticoagulant (NOAC)
