  • Blood pressure and pulse rate at screening within the normal range (systolic 90-140 mmHg, diastolic 40-90 mmHg, pulse rate 40-90bpm).
  • They have the following clinical laboratory test
  • Biochemistry (AST(GOT), ALT(GPT), ALP, LDH and gamma-GTP : within normal range at screening.
  • Haematology (RBC, Hb and Ht) below upper limit normal range at screening.
  • Normal ECG at screening (QTc value of <440msec).
  • They give their consent to be able to abstain from sexual intercourse or use condom for contraception from at screening until post-study screen.
  • They are capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • They are non-smokers (at least 6 months).
  • They are able to attend all visits and complete the study.

  • The subject has an allergy for any drug or idiosyncrasy. This excludes a pollen allergy without current symptoms.
  • The subject has participated in a clinical study or post-marketing study with an investigational or a non-investigational product or device during the previous 4 months of the first dosing.
  • The subject is concurrently participating 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.
  • The subject is positive for syphilis, HBs antigen, HCV antibody, HIV antibody, HTLV-1 antibody.
  • The subject is positive for urine drugs of abuse test.
  • The subject has donated a unit of blood (>400mL) within the previous 4 months or (>200mL) within the previous 1 month of screening.
  • The subject is currently taking regular (or a course of) medication (including prescribed drug, over-the-counter medication and herbal preparations). Medication nor permitted during the study must be discontinued 14 days prior to dosing.
  • The subject has a history or current conditions of drug abuse or alcoholism according to ICD10.
