Exclusion criteria

1. Has a history of or current clinically significant medical illness including (but not limited to) pulmonary, cardiovascular, coagulation disorders, lipid abnormalities, gastrointestinal, immunologic, endocrine (stable thyroid hormone replacement therapy is not excluded), neurologic, psychiatric, or thromboembolic disease, metabolic disturbances, or any other current physical condition that the Investigator considers should exclude the participant, or that could interfere with the interpretation of the study results. 2. Has current or recent (within 6 months) history of gastrointestinal disease, or any surgical or medical condition such as Crohn's disease or liver disease, that could potentially alter the absorption, metabolism, or excretion of the study drug. 3.
