Current or past history of significant cardiovascular, pulmonary, gastrointestinal, renal, hepatic, metabolic, genitourinary, endocrine (including diabetes mellitus, thyroid disorders), malignancy, hematological, immunological, neurological, or psychiatric disease that, in the opinion of the investigator or medical monitor, could compromise either participant safety or the results of the trial.

• •3. Any condition or surgery that could possibly affect drug absorption, including, but not limited to, bowel resections, bariatric weight loss surgery/procedures, gastrectomy, and cholecystectomy.
• •4. Use of any prescription and over-the-counter medications from 28 days prior to first dose of IMP or likely to require concomitant therapy. Vaccinations or boosters within 28 days of planned dosing or while on trial.
• •5. Positive result for human immunodeficiency virus (HIV) antibody, hepatitis B surface antigen, hepatitis B total core antibody, or hepatitis C antibody with detectable viral ribonucleic acid (RNA) levels at Screening.
• •6. Positive drug screen (including cotinine and tetrahydrocannabinol \[THC\]) or a positive test for alcohol.
• •7. Any of the following clinical laboratory test results at the Screening Visit or Check-in (Day -1), which can be confirmed by a single repeat measurement, if deemed necessary:
• •* Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≥2× upper limit of normal (ULN).
• •* Total bilirubin ≥1.5×ULN. If Gilbert's syndrome is suspected, total bilirubin ≥1.5×ULN is acceptable if the conjugated or direct bilirubin fraction is \<20% of total bilirubin.
• •8. Known allergy or hypersensitivity to the IMP, closely related compounds, or any of their specified ingredients.
