Women in the following categories are not considered a woman of childbearing potential: premenarcheal, premenopausal female with one of the following: documented hysterectomy, documented bilateral salpingectomy, documented bilateral oophorectomy. Postmenopausal female is defined as no menses for 12 months without an alternative medical cause. Females on HRT and whose menopausal status is in doubt will be required to use one of the nonhormonal highly effective contraception methods if they wish to continue their hormone replacement therapy (HRT) during the trial. * Have a medical and psychiatric history and a brief physical examination demonstrating no clinically significant contraindications for study participation, in the judgment of the Study Physician and the Principal Investigator. * Be able to provide the names of at least 2 persons who can consistently locate their whereabouts.
