Introduction to Dofetilide
Dofetilide is a class III antiarrhythmic agent, primarily used to treat atrial fibrillation and atrial flutter. It works by blocking the potassium channels in the heart, which helps to restore and maintain a normal heart rhythm.
Clinical Trials: Efficacy and Safety
DIAMOND Low Ejection Fraction Substudy
One of the significant clinical trials involving dofetilide is the Danish Investigation of Arrhythmia and Mortality On Dofetilide (DIAMOND) Low Ejection Fraction Substudy. This study enrolled 506 patients with atrial fibrillation/flutter (AF/Fl), congestive heart failure (CHF), or recent myocardial infarction (MI), and an ejection fraction (EF) of less than 0.35. The trial demonstrated that dofetilide is more effective than placebo in restoring and maintaining sinus rhythm. Pharmacologic or spontaneous cardioversion occurred in 44% of the dofetilide group, compared to 14% in the placebo group. Including electrical cardioversion, sinus rhythm was restored in 59% of the dofetilide group and 34% of the placebo group. Notably, one year after cardioversion, sinus rhythm was maintained in 79% of the dofetilide group versus 42% in the placebo group. The study also found that successful maintenance of sinus rhythm was associated with improved survival and lower hospitalization rates[1][4].
EMERALD Trial
The European and Australian Multicenter Evaluative Research on Atrial Fibrillation—Dofetilide (EMERALD) trial further validated the efficacy of dofetilide. This randomized trial involved 505 patients and evaluated the effectiveness of dofetilide in restoring and maintaining sinus rhythm. Patients were randomized to receive one of three doses of dofetilide, sotalol, or placebo. The results showed that high-dose dofetilide was significantly better than low-dose dofetilide and sotalol in maintaining sinus rhythm. At the end of one year, 66% of patients treated with high-dose dofetilide remained in normal sinus rhythm, compared to 21% in the placebo group and 50% in the sotalol group. The treatment was well tolerated, with a low incidence of serious adverse events[3].
