Note: use of oral contraceptives is not permitted.
* Women of non-child bearing potential are defined as follows: females regardless of age, with functioning ovaries who have a current documented tubal ligation, or who are surgically sterile (i.e. documented total hysterectomy or bilateral oophorectomy), or females who are post-menopausal.

All females must have a negative urine pregnancy test on the day of, and prior to randomization.
