Atrial Fibrillation Trial Phases
72 research organizations are sponsoring atrial fibrillation trials.
About Atrial Fibrillation
Atrial fibrillation (AFib) is the most common type of heart arrhythmia, causing an irregular and often rapid heartbeat. It significantly increases the risk of stroke, heart failure, and other complications. Treatment includes blood thinners, heart rate or rhythm control medications, and procedures like ablation.
Clinical trials are advancing new treatments for atrial fibrillation. Currently, 100 studies are recruiting a combined 157,308 participants across the United States. Research is being conducted by 72 organizations including Heart Rhythm Clinical and Research Solutions, LLC, Medtronic, American Heart Association and 69 others.
2026 Atrial Fibrillation Research Landscape
As of July 2026, the atrial fibrillation clinical trial landscape includes 100 actively recruiting studies across 173 cities in the United States. These studies are collectively seeking 157,308 participants, with an average enrollment target of 1,573 per study.
The research spans multiple phases of development: 42 studies are in NA, 6 studies are in PHASE4, 6 studies are in PHASE3, 6 studies are in PHASE2, 2 studies are in PHASE1, 1 study is in EARLY_PHASE1. The presence of Phase 3 trials indicates that some atrial fibrillation treatments are in late-stage testing and may be approaching regulatory review.
Research is being led by 72 different organizations, including Heart Rhythm Clinical and Research Solutions, LLC, Medtronic, American Heart Association, VA Office of Research and Development, AtriCure, Inc., and 67 others. The large number of sponsors reflects significant research interest and investment in atrial fibrillation treatment advancement.
