Researchers are evaluating the effect of abelacimab compared to a placebo on reducing the rate of ischemic stroke or systemic embolism in patients with atrial fibrillation who are considered unsuitable for oral anticoagulation therapy. This Phase 3 study focuses on high-risk patients, including those who may have increased bleeding risks and cannot or choose not to take standard blood thinners. Participants will be randomly assigned to receive either abelacimab 150 mg or a matching placebo through a monthly subcutaneous injection. The study is designed as a double-blind, placebo-controlled trial to monitor the safety and efficacy of abelacimab over a period of up to 30 months. During the study, participants will be closely monitored for the time to first occurrence of ischemic stroke, systemic embolism, and bleeding events classified by the Bleeding Academic Research Consortium. Researchers will also track cardiovascular and all-cause mortality, as well as other cardiovascular events. Participants will undergo regular assessments, including electrocardiograms and clinical evaluations, throughout the trial to ensure safety and collect data on treatment effects.
