Criteria

Inclusion criteria:

  • Healthy Japanese adult males between 20 and 64 yeas of age, inclusive.
  • Healthy subjects are defined as individuals who are free from clinically significant disease as determined by their medical history, physical examination, clinical laboratory examinations, vital sign, 12-lead ECG, immunology tests and urinary drug screen test.
  • Bodyweight >50 kg and body mass index (BMI) between 18.5 and 25.0 at screening.
  • Subjects must be capable of providing written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • Baseline QTc interval <450 msec.
  • Non-smoker or ex-smoker having ceased smoking for at least 6 months.
  • Clinical laboratory examination (AST, ALT, ALP and GGT) at screening are within the normal range.
  • The subject is able to attend all visits and complete the study.

Exclusion criteria:

  • Any clinically relevant abnormality identified on the screening physical examination, vital sign measurement, 12-lead ECG recording and/or clinical laboratory examination that is deemed by the principal investigator and/or medical monitor to make the subject ineligible for inclusion because of a safety concern.
  • History of regular alcohol consumption exceeding, on average, 14 drinks/week for men (1 drink = 5 ounces (150 mL) of wine or 350 mL of beer or 1.5 ounces (45 mL) of 80 proof distilled spirits) within 6 months of screening.
  • Positive for urine drug at screening.
  • Positive for syphilis, HIV antibody, Hepatitis B surface antigen, Hepatitis C antibody or HTLV-1 antibody at screening.
  • Use of prescription or no-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study medication.
  • Consumption of grapefruit juice or food within 7 days prior to the first dose of study medication.
  • A history of cholecystectomy or biliary tract disease including a history of liver disease with elevated liver function tests of known or unknown etiology.
  • Donation of blood in excess of 400mL within 4 months or 200mL within 1 months prior to at screening.
  • History of drug abuse, or current conditions of drug abuse or alcoholism.
  • Participation in a clinical study or post-marketing study with an investigational or a non-investigational product or device within 4 months of preceding the first dose of study medication.
  • Participation in another clinical study or post-marketing study in which the subject is or will be exposed to an investigational or a non-investigational product or device.
  • History of asthma, anaphylaxis or anaphylactoid reactions, severe allergic responses.
  • The subject has an allergy for any drug or idiosyncrasy. This excludes a pollen allergy without current symptoms.
  • History of sensitivity to heparin or heparin-induced thrombocytopenia.
