Significant concurrent medical diseases including uncompensated congestive heart failure, myocardial infarction within 12 months, stable or unstable angina pectoris, uncontrolled hypertension, severe pulmonary disease, history of human immunodeficiency virus (HIV) infection, central nervous system demyelinating events suggestive of multiple sclerosis

8. Presence or history of confirmed blood dyscrasias

9. History of any viral hepatitis within 1 year prior screening or history of any drug-induced liver injury at any time prior to screening
