NCT05878535

Brief Summary

The aim of this multicenter, pragmatic, open-label, randomized, placebo-controlled clinical trial is to test whether repurposing metformin for the treatment of atrial fibrillation will be effective in decreasing patients' hospitalization, adverse major cardiovascular events, and non-cancer death. Participants will be randomized into 2 study arms (385 participant each), whereby:

  • The Metformin Group (MG): will receive metformin oral tablets in addition to the standard rate/rhythm control strategy and anticoagulation.
  • The Placebo Control Group (PCG): will receive placebo oral tablets as a control group in addition to the standard rate/rhythm control strategy and anticoagulation. Then both arms will be compared according to the these endpoints:
  • The primary endpoint is hospitalization due to an episodic AF or an AF with a rapid or slow ventricular response (in the case of permanent AF).
  • The secondary endpoint is a composite of non-fatal major cardiovascular adverse events or non-cancer death. The non-fatal major cardiovascular adverse events include:
  • Hospitalization due to heart failure.
  • Non-fatal myocardial infarction.
  • Non-fatal stroke.
  • Hospitalization due to unstable angina.

Study Arms (2)

The Metformin Group (MG)

ACTIVE COMPARATOR

The group (n=385) will receive metformin oral tablets in addition to the standard rate/rhythm control strategy and anticoagulation. • Drug: metformin 850 mg oral tablets. Prescribed: Once daily PO with meals and 200 mL of water. The dose can be up-titrated to 1500-2000 mg divided q8-12hr with meals in enrolled diabetic patients as a monotherapy or combined with sulfonylurea. Other Name: Glucophage.

Drug: Metformin

The Placebo Control Group (PCG)

PLACEBO COMPARATOR

The group (n=385) will receive placebo oral tablets in addition to the standard rate/rhythm control strategy and anticoagulation. • Drug: Placebo oral tablets. Prescribed: Once daily PO with meals and 200 mL of water. Other Name: Placebo

Drug: Placebo

Interventions

Metformin 850 mg oral tablets. Prescribed: Once daily PO with meals and 200 mL of water. The dose can be up-titrated to 1500-2000 mg divided q8-12hr with meals in enrolled diabetic patients as a monotherapy or combined with sulfonylurea.

Also known as: Glucophage, Glumetza, and Riomet.
