Can a blood thinner prevent strokes in brain bleed survivors?

NCT ID NCT03907046

Disease control Sponsor: Yale University Source: ClinicalTrials.gov ↗

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares two medicines—apixaban (a blood thinner) and aspirin—in people who have had a brain bleed (intracerebral hemorrhage) and also have an irregular heartbeat (atrial fibrillation). The goal is to see which drug better prevents future strokes or death. About 700 participants will be randomly assigned to take either apixaban or aspirin for up to several years.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: Apixaban (Eliquis) and aspirin
What this could lead to: If apixaban works better than aspirin, it could become the preferred treatment to prevent strokes in people who have had a brain bleed and have atrial fibrillation.
What could go wrong: This is a large phase 3 trial, but results may not apply to all patients. Apixaban could increase the risk of another brain bleed, and the benefit over aspirin is not yet proven.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Inclusion Criteria: * 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 Exclusion Criteria: * Index event is hemorrhagic transformation of a brain infarction or hemorrhage into a tumor * History of earlier ICH within 12 months preceding index event * Active infective endocarditis * 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). * Previous or planned left atrial appendage closure * Clinically significant bleeding diathesis * Serum creatinine ≥2.5 mg/dL * Active hepatitis or hepatic insufficiency with Child-Pugh score B or C * Anemia (hemoglobin \<8 g/dL) or thrombocytopenia (\<100 x 10\^9/L) that is chronic in the judgment of the investigator * Pregnant or breastfeeding * Known allergy to aspirin or apixaban * Concomitant participation in a competing trial * Considered by the investigator to have a condition that precludes safe or active participation in the trial * Persistent, uncontrolled systolic blood pressure (≥180 mm Hg) * ICH caused by an arteriovenous malformation (AVM) that has not yet been secured
