Inclusion criteria

1. Males and/or females between the ages of 19 and 55 years, inclusive.

   2. Barrier method (condom or diaphragm) with spermicide for at least 7 days prior to screening through 30 days beyond study completion;
   3. Stable hormonal contraceptive (e.g., oral, depo injection, transdermal patch, or vaginal ring) for at least 3 months prior to Day 1 of Period 1 through 30 days beyond completion of study;

   Abstinence is not an acceptable form of contraception; however, abstinent female subjects may be admitted to the study if they agree, and have signed a statement to the effect, that upon becoming sexually active, will use a condom with spermicide from screening through 30 days beyond completion of the study.

Females of non-childbearing potential should be surgically sterile (bilateral tubal ligation with surgery at least 6 months prior to study or hysterectomy and/or bilateral oophorectomy at least 3 months prior to Day 1 of Period 1) or postmenopausal >2 years prior to Day 1 of Period 1. A follicle stimulating hormone (FSH) concentration >40 miU/mL must be obtained and recorded for any postmenopausal females.

4. Good general health as determined by the Principal Investigator's (PI) review of medical history, physical examination, vital sign measurements, electrocardiogram (ECG), and clinical laboratory measures.

5. Within 15% of ideal body weight (Table of 'Desirable Weights of Adults' Metropolitan Life Insurance Company, 1983).

If a subject's hemoglobin drops below 11.0 g/dL during the study, the subject may be dropped from the study at the discretion of the PI.
2. Any disease or condition, which could impact absorption, distribution, metabolism, or elimination of the study drugs (as determined by the PI/designee).
3. Alcoholism or medicinal product or drug abuse within the past two years or excessive alcohol consumption (more than 10 units per week) (one unit is defined as 5 ounces of wine, 12 ounces of beer, or 1.5 ounces of spirits (i.e., 'hard' liquor such as gin, whiskey, or vodka, et. al.).
