- Cerebral venous sinus thrombosis, antiphospholipid syndrome, or a history of heparin-induced thrombocytopenia and thrombosis (HITT or HIT type 2),
- Suspected or known current alcohol or drug addiction,
- Any other significant disease, disorder or finding that could significantly increase the subject's risk for participation in the study, affect the subject's ability to participate in the study, or impair the interpretation of study data; severe and/or uncontrolled cardiovascular disease, respiratory disease, gastrointestinal disease, liver disease, kidney disease, endocrine disorder, and neurological disease (mild/moderate well-controlled comorbidities are permitted),
