Primary Aim: To determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF).
Secondary Aim: To determine if apixaban, compared with aspirin, results in better functional outcomes as measured by the modified Rankin Scale.

Active Comparator: Apixaban
Apixaban dosing will be 5 mg tablet in morning and 5 mg tablet in evening. A reduced dose of 2.5 mg tablet in morning and 2.5 mg tablet in evening will be used if: (1) ≥2 of the following are present: age ≥80 years, body weight ≤60 kg, or serum creatinine 1.5-2.4 mg/dL, or (2) Patient is taking a strong CYP3A4/pGP inhibitor (e.g., ketoconazole, itraconazole, ritonavir, or clarithromycin).
|
Drug: Apixaban
Apixaban is an oral anticoagulant of the Factor Xa inhibitor class.
Other Name: Eliquis |
Placebo Comparator: Aspirin
Aspirin dose will be 81 mg tablet once daily.
|
Drug: Aspirin
Aspirin is an oral antiplatelet drug. |

- Modified Rankin Scale (mRS) score [ Time Frame: Change from baseline to 12 months; change over duration of follow-up ]Measure of neurologic disability (0=no disability to 6=dead)

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
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).
