Participant is considered to be medically healthy, as determined by a responsible and experienced investigator, based on a clinical evaluation (including medical history, physical examination, clinical laboratory tests, vital sign measurements, and a 12-lead ECG performed, and the results of clinical chemistry, hematology, coagulation, and urinalysis carried out at Screening and Day -1. 5. Participant has alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin levels \<1.5 × the upper limit of normal (ULN) at Screening and at Day -1. 6. Participant has normal renal function (creatinine clearance ≥90 mL/min) as evidenced by normal estimated glomerular filtration rate (eGFR) measured by the CKD-EPI equation. 7. Participant agrees to the following during the treatment periods and for at least 7 days after the last dose of study treatment: 1. Refrain from donating or preserving sperm; PLUS either 2. Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent. OR 3. Must agree to use a male condom when having sexual intercourse with women of childbearing potential (WOCBP). An additional form of contraception should also be used by the female partner if she is of childbearing potential. 8. Has sufficiently good venous access in at least one arm to confidently enable serial blood sampling. Exclusion Criteria: 1. Participant has a history or presence of oncologic, cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, ocular, endocrine, immunologic, dermatologic, musculoskeletal, neurologic, psychiatric, or other disease or condition or laboratory test abnormality that in the investigator's judgment poses a significant risk to the safety of the participant or the achievement of study objectives. 2. Participant has a history or presence of any condition possibly affecting drug absorption (e.g., gastrectomy). 3. Participant has a medical history or abnormal findings at Screening or Day -1 that the investigator judges may put at risk achieving the objectives of the study or protecting the safety of the participant. 4.

Participant has a known hypersensitivity or intolerance to any of the study treatments, or excipients thereof, or a history of drug or other allergy that, in the opinion of the investigator or sponsor medical monitor, contraindicates their participation. 20.
