Trial Outcomes & Findings for Use of Dapagliflozin to Reduce Burden of Atrial Fibrillation in Patients Undergoing Catheter Ablation of Symptomatic Atrial Fibrillation (NCT NCT04792190)

NCT ID: NCT04792190

Last Updated: 2024-12-04

Results Overview

For the primary endpoint of AF burden, defined as percentage of time spent in AF (i.e. amount of time spent in AF divided by the total amount of time a patient was monitored), the student's t-test will be used to statistically compare the placebo group vs. the active treatment group. This approach is subject to an examination of the distribution of the percent time in AF. AF data will be collected using a cardiac implantable electronic device (CIED). AF burden assessed at 6-12 months following catheter ablation of AF, defined as percentage of time spent in AF (i.e. amount of time spent in AF divided by the total amount of time a subject was monitored).

Measure
Intervention Management Arm (Dapagliflozin)
A block randomization method will be use to randomize subjects to treatment with dapagliflozin 10 mg once daily. Subjects will take 1 blinded tablet of study drug (dapagliflozin) dosed once daily, per the randomization scheme, for 12 months. Each subject will be dispensed 35 blinded doses per month, during each month of participation in the trial. Quarterly pill counts will be performed to track compliance. dapagliflozin: Subjects will take 1 blinded tablet of study drug (dapagliflozin 10 mg) dosed once daily, for 12 months.
Control Arm (Placebo)
Subjects will take 1 blinded tablet of placebo drug dosed once daily, per the randomization scheme, for 12 months. Each subject will be dispensed 35 blinded doses per month, during each month of participation in the trial. Quarterly pill counts will be performed to track compliance. Placebo: Subjects will take 1 blinded capsule of placebo drug dosed once daily

The AFEQT questionnaire is an AF-specific health-related quality of life questionnaire designed to be used in clinical research. The responses on the AFEQT are scored on a Likert scale, 1 = "Not at all…" to 7 = "Extremely". Scores range from 0 to 100. A score of 0 corresponds to complete disability and a score of 100 corresponds to no disability.
