Researchers are evaluating the effect of abelacimab compared to a placebo in patients with atrial fibrillation (AF) who are considered unsuitable for oral anticoagulation therapy. This study focuses on people at high risk for ischemic stroke or systemic embolism and aims to assess the safety and effectiveness of abelacimab in preventing these events. The study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial involving patients with AF who have specific risk factors and treatment challenges. Participants will receive either abelacimab, provided as a liquid in vials at 150 mg/mL, or a matching placebo liquid. The study design includes parallel groups with blinded treatment assignment. The trial does not describe additional treatment phases or extensions but focuses on the comparison of abelacimab and placebo over the study duration. During the study, participants will be monitored for up to 30 months to measure the time until the first occurrence of ischemic stroke or systemic embolism, as well as the time until the first occurrence of serious bleeding as defined by the Bleeding Academic Research Consortium (BARC) type 3c/5 bleeding. Safety and efficacy will be closely evaluated, with ongoing assessments to track these outcomes throughout the follow-up period.
