This is a Phase 1, open-label, nonrandomized, single-dose mass balance and metabolite identification study in healthy male subjects.

Inclusion Criteria:

1. Males, of any race, between 18 and 55 years of age, inclusive, at screening.
2. Body mass index between 18.0 and 32.0 kg/m2, inclusive, at screening.
3. In good health, determined by no clinically significant findings from medical history, physical examination (assessed only at check-in), 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).
4. History of a minimum of 1 bowel movement per day.

Exclusion Criteria:

1. Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, psychiatric, or other disorder, as determined by the investigator (or designee).
2. History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (uncomplicated appendectomy and hernia repair will be allowed; cholecystectomy will not be allowed).
3. Positive urine drug screen, including cotinine, at screening; positive alcohol test result or positive urine drug screen, including cotinine, at check-in.
4. Use of any drugs or substances known to be strong or moderate inhibitors or inducers of cytochrome P450 (CYP)3A4 or P-glycoprotein substrates within 30 days prior to study drug administration. Medications will be reviewed by the medical monitor to determine acceptability for the study.
