• Voluntarily sign a Research Ethics Committee (REC)-approved informed consent form to participate in the study after all relevant aspects of the study have been explained and discussed with the subject.
• Have Hematology, Coagulation, Clinical Chemistry and Urinalysis test results that are within normal, allowable limits (if out-of-range, must be considered clinically significant to be exclusionary) and performed within 21 days of receiving first dose of test material.
• Have a BMI (Body Mass Index) between 18.0 and 30.0 kg/m^2.
• Be clear of any history of HIV and hepatitis B and C.

For the purposes of this study, this is defined as the subject being amenorrheic for at least 12 consecutive months or at least 6 weeks post-surgical bilateral oophorectomy with or without hysterectomy. (Menopausal status will be confirmed by demonstrating levels of follicle stimulating hormone (FSH) of 20 - 138 mIU/ml and oestradiol < 20 pg/ml at entry. In the event a subject's menopause status has been clearly established (for example, the subject indicates she has been amenorrheic for 10 years), but FSH and/or oestradiol levels are not consistent with a post-menopausal condition, determination of subject eligibility will be at the discretion of the principal investigator following consultation with the sponsor.
• Subject agrees to refrain from consumption of grapefruits and/or grapefruit juice from 7 days prior to day -1 of treatment visit 1 through to the end of subject's final study visit.
