First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two experimental drugs, REGN7508 and REGN9933, to prevent strokes in people with atrial fibrillation (an irregular heartbeat) who cannot or choose not to take standard blood thinners. About 2,628 participants will receive one of the drugs or a placebo to see if they reduce the risk of stroke or blood clots. The goal is to find a safer option for those at high risk of bleeding.
