Dapagliflozin to Prevent Atrial Fibrillation Recurrence After Transcatheter Pulmonary Venous Isolation.
A Early Phase 1 study testing Dapagliflozin in people with Atrial Fibrillation Recurrent and Pulmonary Venous Isolation, run by G.Gennimatas General Hospital at 2 sites in Greece.
Trial summary
Transcatheter left atrial antral ablation, aiming at complete electrical isolation of the pulmonary veins (PVI), has become mainstay in atrial fibrillation (AF) treatment. This approach has been proved superior to medical rhytmh control strategy in maintaining sinus rhythm. Read more about this study

About this study
Transcatheter left atrial antral ablation, aiming at complete electrical isolation of the pulmonary veins (PVI), has become mainstay in atrial fibrillation (AF) treatment. This approach has been proved superior to medical rhytmh control strategy in maintaining sinus rhythm. Moreover PVI has been associated with significant survival benefit in patients with heart failure and reduced left ventricular ejection fraction. Nevertheless, despite progress in the field of catheter ablation, recurrence rates remain high.
Inhibitors of type 2 sodium- glucose co-transporter (SGLT2i) is a relatively recent addition to the array of anti-diabetic agents, becoming part of everyday clinical practice. However, although SGLT2i were first used solely as antidiabetics because of their glycosuric effect, further research demonstrated that these drugs may independently reduce cardiovascular events, especially in patients with heart failure, a benefit that was consistent among diabetic and non-diabetic patients. Moreover, pleiotropic effects have been observed, including a reno-protective action.

These findings suggest that SGLT2i mechanisms of action extend beyond the obvious increase in urinary sodium and glucose excretion. Various studies propose that these drugs promote favourable metabolic changes in myocardial energetics, while they also inhibit inflamation and sympathetic activation, resulting in restriction of induced fibrosis and structural remodeling, which are key elements in atrial fibrillation generation and maintenance.
These findings suggest that the use of SGLT2i could offer antiarrhythmic benefit by reducing and/or reversing structural and electrical remodeling, leading to the assumption that use of theese drugs could reduce recurrences after transcatheter AF ablation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DapagliflozinDrug
Patients rendomized in this arm will receive dapagliflozin at a target dose of 10mg once daily.
PlaceboDrug
Patients rendomized in this arm will receive placebo.
| Study group | Role | What they receive |
|---|---|---|
| Dapagliflozin | Active comparator | Patients who will be randomized to receive dapagliflozin following catheter ablation. Receives: Drug: Dapagliflozin |
| Placebo | Placebo comparator | Patients who will be randomized to receive placebo following catheter ablation. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Comparison of survival free of AF/ atrial tachycardia (AT) recurrence between the two study arms.
AF/AT are defined as any episodes of AF or atrial flutter or other re-entrant atrial tachycardia recorded either on surface ECG or on Holter monitoring and lasting for at least 30 s. All episodes will be reviewed by two independent electrophysiologists, who will be blinded as to patient identity and randomization.The first 3 months after the ablation procedure will be regarded as a blanking period.
Measured: 18 months from the PVI procedure

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Transcatheter left atrial antral ablation, aiming at complete electrical isolation of the pulmonary veins (PVI), has become mainstay in atrial fibrillation (AF) treatment. This approach has been proved superior to medical rhytmh control strategy in maintaining sinus rhythm. Moreover PVI has been associated with significant survival benefit in patients with heart failure and reduced left ventricular ejection fraction. Nevertheless, despite progress in the field of catheter ablation, recurrence rates remain high.
Inhibitors of type 2 sodium- glucose co-transporter (SGLT2i) is a relatively recent addition to the array of anti-diabetic agents, becoming part of everyday clinical practice. However, although SGLT2i were first used solely as antidiabetics because of their glycosuric effect, further research demonstrated that these drugs may independently reduce cardiovascular events, especially in patients with heart failure, a benefit that was consistent among diabetic and non-diabetic patients.
