- Written informed consent obtained from the subject.
- Free of obvious health problems as established by medical history, clinical examination and clinical laboratory assessment before entering into the study.
- Female subjects of non-childbearing potential (defined as pre-menarche, current tubal ligation, hysterectomy, ovariectomy or post-menopause) may be enrolled in the study.
- Female subjects of childbearing potential may be enrolled in the study, if the subject:
