• Female subjects of childbearing potential must be using a medically acceptable form of birth control for at least 1 month prior to screening (3 months on oral contraceptives), e.g., oral or patch contraceptives, intrauterine device, Depo-Provera, or double-barrier and have a negative pregnancy test at Screening and prior to surgery. Female subjects of non-childbearing potential must be amenorrheic for at least 2 years or had a hysterectomy and/or bilateral oophorectomy.
