Más betegség

• Clinically significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure (New York Heart Association > Class 2), unstable angina, or myocardial infarction within 6 months of screening, or any Class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification
• Uncontrolled hypertension despite optimal medical management (per investigators assessment)
• Patient has poorly controlled diabetes (per investigators assessment)
• Non-healing wound, ulcer or bone fracture in a short time
• Known bleeding diathesis or hemophilia
• Known history of infection with human immunodeficiency virus (HIV) or active stage of infection with hepatitis C virus (HCV) or hepatitis B virus (HBV) . Active HBV infection must be confirmed by a positive test for HBV surface antigen or a positive test for hepatitis B core antibody with a positive determination of HBV DNA by polymerase chain reaction (PCR). For Hepatitis C virus (HCV), confirmation must be made by a positive test for HCV antibodies, unless the subject has been treated and has shown a sustained virological response. Note: Subjects with positive HCV antibodies who have been treated and have shown a sustained virological response (negative virus detection for at least 6 months after completing treatment) will not be excluded.
• Unable to swallow capsules or disease significantly affecting gastrointestinal function
• Life-threatening illness, medical conditions, or organ dysfunctions that may endanger the safety of the subject or put the study outcomes at risk.
