Exclusion Criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details


- Women who are pregnant or breast feeding


- Women of child bearing potential who are unwilling to meet the study requirements for
pregnancy testing or are unwilling or unable to use an acceptable method to avoid
pregnancy


- Atrial fibrillation due to reversible causes, such as thyrotoxicosis or pericarditis


- Valvular disease requiring surgery


- Planned ablation procedure for atrial fibrillation to be performed within 3 months

including but not limited to those with:


- Active peptic ulcer disease


- Platelet count <100,000/mm^3 or hemoglobin <10g/dL


- Recent stroke (within 10 days)


- Documented hemorrhagic tendencies or blood dyscrasias


- Current alcohol or drug abuse or psychosocial reasons that make study participation
impractical

calculated creatinine clearance <25 mL/min is excluded


- Alanine transaminase or aspartate aminotransferase levels >2 times upper limit of
normal (ULN) or a total bilirubin level >1.5 times ULN (unless an alternative
causative factor [such as Gilbert's syndrome] is identified)

- Use of an investigational drug or device within the past 30 days or prior
randomization into an apixaban clinical study


- Patients who are compulsorily detained for treatment for a psychiatric or physical
illness
