Anticoagulation in ICH Survivors for Stroke Prevention and Recovery

Prior treatment

• Previous or planned left atrial appendage closure
• Concomitant participation in a competing trial

Other illness

• Index event is hemorrhagic transformation of a brain infarction or hemorrhage into a tumor
• History of earlier ICH within 12 months preceding index event
• Clear indication for anticoagulant drugs (e.g., requires anticoagulation for deep vein thrombosis or pulmonary embolism) or antiplatelet drugs (e.g., requires aspirin or clopidogrel for recent coronary stent).
• Clinically significant bleeding diathesis
• Active hepatitis or hepatic insufficiency with Child-Pugh score B or C
• Known allergy to aspirin or apixaban
• Considered by the investigator to have a condition that precludes safe or active participation in the trial

Lab values

• Serum creatinine ≥2.5 mg/dL
• Anemia (hemoglobin \<8 g/dL) or thrombocytopenia (\<100 x 10\^9/L) that is chronic in the judgment of the investigator

Other

• Active infective endocarditis
• Pregnant or breastfeeding
• Persistent, uncontrolled systolic blood pressure (≥180 mm Hg)
• ICH caused by an arteriovenous malformation (AVM) that has not yet been secured

• Age at least 18 years
• Intracerebral hemorrhage (ICH) (including primary intraventricular hemorrhage) confirmed by brain CT or MRI
• Can be randomized within 14-180 days after ICH onset
• Non-valvular AF (defined as atrial fibrillation or atrial flutter), documented by electrocardiography or a physician-confirmed history of prior AF
• Provision of signed and dated informed consent form by patient or legally authorized representative
• For females of reproductive potential: use of highly effective contraception
