A study to evaluate the effect of abelacimab relative to placebo on the rate of ischemic stroke or systemic embolism (SE) in patients with Atrial Fibrillation (AF) who have been deemed by their responsible physicians or by their own decision to be unsuitable for oral anticoagulation therapy.
Patient is able to understand and has provided written informed consent to participate in the trial
Diagnosed Atrial Fibrillation (AF) or atrial flutter (documented on an electrocardiogram (ECG) or monitor recording)
Age 65-74 and a CHA2DS2VASc ≥4 OR age ≥75 and a CHA2DS2VASc ≥3
Patient is judged by the responsible physician to be unsuitable for oral anticoagulation because the risks outweigh the benefits or the patient is unwilling to take oral anticoagulation AND this determination was made prior to and independent of the study
AF due to an ongoing acute reversible cause (e.g., cardiac surgery, pulmonary embolism (PE), untreated hyperthyroidism, alcohol use)
Patients who within 60 days prior to randomization (1) received a vitamin K antagonists (VKA) (e.g., warfarin, phenprocoumon, acenocoumarol) or a direct oral anticoagulant (DOAC) such as, dabigatran, rivaroxaban, apixaban, or edoxaban or (2) were newly diagnosed with AF
Patients with an intracranial or intraocular bleed within the 3 months prior to screening or any history of spontaneous intracerebral hemorrhage at any time in the absence of antithrombotic treatment
Any stroke within 14 days before randomization or transient ischemic attack (TIA) within 3 days before randomization
