Phase 2 Randomized Trial of Oral AP31969 Tablets Versus Placebo for Controlling Atrial Fibrillation Rhythm

What this Trial Is About

This trial evaluates different doses of the drug AP31969 to control the rhythm of atrial fibrillation AF and to determine its safety. The study is a randomized Phase 2 trial comparing AP31969 to a placebo in adults diagnosed with paroxysmal or persistent AF who have a measurable AF burden. The study aims to reduce AF burden and improve quality of life using oral medication. Participants are assigned randomly to receive one of several doses of AP31969 100 mg, 200 mg, 350 mg, or later 500 mg or a placebo. All treatments are given as tablets taken orally twice daily for 12 weeks. The study includes three periods screening up to 4 weeks, treatment 12 weeks, and a follow-up period of 30 days. Participants will have an implantable loop recorder to monitor heart rhythm continuously. During the study, participants will attend scheduled visits where blood and urine tests, electrocardiograms, and other assessments will be performed. Researchers will track AF burden, the number of AF episodes, quality of life changes, and episodes of ventricular tachycardia. The total participation time is about 20 weeks, including all study periods, with safety and treatment effects monitored carefully.
