Special Criteria Regarding Fertility and Contraception Female subjects of reproductive potential (women who have reached menarche or women who have not been post-menopausal for at least 24 consecutive months, i.e., who have had menses within the preceding 24 months, or have not undergone a sterilization procedure \[hysterectomy or bilateral oophorectomy\]) must have a negative serum or urine pregnancy test performed at screening. Due to the high-risk level of this study, while enrolled, all subjects must agree not to participate in a conception process (e.g., active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization). Additionally, if participating in sexual activity that could lead to pregnancy, the study subject must agree to use reliable and double barrier methods of contraception during the follow-up period of the protocol. Acceptable birth control includes a combination of two of the following methods: • Combined estrogen and progestin containing hormonal contraception associated with inhibition of ovulation given orally, intravaginally, or transdermally • Progestin-only hormonal contraception associated with inhibition of ovulation given orally, by injection, or by implant • Intrauterine device (IUD) • Intrauterine hormone-releasing system (IUS) • Vasectomized partner • Sexual abstinence: considered a highly effective method only if defined as refraining from heterosexual intercourse during an entire period of risk associated with the study treatment. The reliability of sexual abstinence will be evaluated in relation to the duration of the study and to the usual lifestyles of the patient. • Female sterilization • Fallopian tube implants (if confirmed by hysterosalpingogram) Oocyte donation is prohibited during the duration of participation on this protocol and for 1 month after the last dose of study drug. Subjects who are not of reproductive potential (women who are premenarche or have been post-menopausal for at least 24 consecutive months which is non-therapy induced or have undergone hysterectomy tubal ligation, salpingectomy, and/or bilateral oophorectomy or men who have documented azoospermia) are eligible without requiring the use of contraception.
