Ages Eligible for Study:   20 Years to 45 Years   (Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   Yes


  1. Men aged 20 to 45 years inclusive at screening. Sexually active men must agree to use a medically acceptable form of contraception during the study and continue it for 12 weeks after test article administration.
  2. Body mass index (BMI) in the range of 17.6 to 26.4 kg/m2 and body weight ≥45 kg.

    BMI is calculated by taking the subject's weight, in kilograms, divided by the square of the subject's height, in meters, at screening: BMI = Weight (kg)/[Height (m)]2.

  3. Healthy as determined by the investigator on the basis of screening evaluations.
  4. Nonsmoker or smoker of fewer than 10 cigarettes per day as determined by history. Must be able to abstain from smoking during the inpatient stay.
  5. Have a high probability for compliance with and completion of the study.

  5. Any significant cardiovascular disease, hepatic, renal, respiratory, gastrointestinal, endocrine, immunologic, dermatologic, hematologic, neurologic, or psychiatric disease.
  6. Any surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the test article (eg, resection of liver, kidney, gallbladder, or gastrointestinal tract).
  7. Acute disease state (eg, nausea, vomiting, infection, fever, or diarrhea) within 7 days before study day 1).
  8. History of drug abuse within 1 year before study day 1.
  9. Admitted alcohol abuse or history of alcohol use that may interfere with the subject's ability to comply with the protocol requirements.

    Physical and Laboratory Findings

  10. Clinically significant electrocardiogram (ECG) abnormalities.
  11. Any clinically important deviation from normal limits in physical examination findings, vital sign measurements, 12-lead ECGs, or clinical laboratory test results.
  12. Positive serologic findings for human immunodeficiency virus (HIV) antigen and antibodies, hepatitis B surface antigen (HBsAg), and hepatitis C virus (HCV) antibodies.
  13. Positive findings of urine drug screen (eg, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, opiates, and phencyclidine [PCP]).
  14. Troponin T or CK-MB levels above reference range at screening. Allergies and Adverse Drug Reactions
  15. History of any clinically important drug allergy (eg, relapsing dermatitis, drug hypersensitivity, drug allergy, hypersensitivity to ingredient in the test articles, angioedema).

    Prohibited Treatments

  16. Use of any investigational drug within 90 days before study day 1 or prescription drug within 30 days before study day 1.
  17. Tobacco use or the consumption of any caffeine-containing products (eg, coffee, tea, chocolate, or carbonated beverages) or alcoholic beverages within 72 hours before study day 1 until the end of the inpatient confinement period.
