Inclusion Criteria
  • Male adults, 18 to 45 years of age, inclusive
  • Body mass index (BMI) from 18 to 32 kg/m2, inclusive

  • Willingness to abstain from alcohol and xanthine-containing beverages or food (coffee, tea, cola, chocolate and "energy drinks") from 72 hours prior to the first dose until discharged
  • Willingness to avoid prolonged sun exposure and guard against sunburn during study & follow-up
Exclusion Criteria
  • Clinically significant medical history or findings in physical examination, vital signs, or laboratory test results prior to study start
  • Positive screening tests for hepatitis B or C, HIV, alcohol, drugs of abuse, or tobacco
  • Regular smoking within 6 months prior to first dosing. Subjects should avoid smoky environments for at least 1 week prior to each cotinine screen
  • Excessive alcohol consumption
  • Use of any metabolic inducers (including herbals such as St. John's Wort) within 4 weeks or 5 half-lives (whichever is longer) before the first dose of study medication, including but not limited to: rifampin, rifabutin, glucocorticoids, carbamazepine, phenytoin and phenobarbital
  • Regular work with ionizing radiation or radioactive material
  • Subjects enrolled in a previous radiolabel study or who have received radiotherapy within 12 months prior to first dosing such that total radioactivity over a 12 month period would exceed an acceptable radiation burden > 0.1 mSv
  • Exposure to radiation for diagnostic reasons (except dental X-rays and plain X-rays of thorax and bony skeleton [excluding spinal column]), during work or participation in a medical trial in the previous year
  • Strenuous activity, sunbathing, or contact sports are not allowed from 4 days prior to entry into the clinical site until study follow-up
  • Participation in an investigational drug or device study within 60 days (or 6 months for biologic therapies) prior to first dosing
