Key Inclusion Criteria:

• Males, of any race, between 19 and 55 years of age, inclusive.
• In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital sign measurements, and clinical laboratory evaluations (congenital nonhemolytic hyperbilirubinemia [eg, suspicion of Gilbert's syndrome based on total and direct bilirubin] is not acceptable) at Screening and Check-in as assessed by the Investigator (or designee).

• History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (cholecystectomy will not be allowed; uncomplicated appendectomy and hernia repair will be allowed).
• Presence of any other condition (including surgery) known to interfere with the absorption, distribution, metabolism, or excretion of medicines.
• Use of any sensitive substrates of cytochrome P450 (CYP)2C9 or CYP3A4/5, or inhibitors of CYP3A4 within 30 days prior to IMP administration (Day 1).
• Donation or loss of ≥ 550 mL blood from 3 months prior to Screening, plasma from 2 weeks prior to Screening, or platelets from 6 weeks prior to Screening.
