Women who have had a complete surgical hysterectomy or are postmenopausal are exempt from this requirement. Medically acceptable forms of birth control include oral contraceptives, injectable or implantable methods, intrauterine devices, tubal ligation (if performed more than one year before screening), or double barrier contraception. Sexually active men must agree to use a medically acceptable form of contraception during the study and continue its use for at least 12 weeks after the last dose of study drug; and
