• Participant has white blood cell count >25 x 109/L (Note: Hydroxyurea and cytarabine are permitted to mean this criterion).
• The effects of the study drug on the developing human fetus or transmission through breast feeding are unknown. Therefore, nursing women and women with a positive urine pregnancy test and excluded. Additionally, women of child-bearing potential (WOCBP) and men who are sexually active with WOCBP who are not willing to maintain adequate contraception are excluded.
• a. WOCBP includes all female participants between the onset of menses (as early as 8 years of age) to 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following: i. Postmenopausal (no menses in greater than or equal to 12 consecutive months).
• ii. History of hysterectomy or bilateral salpingo-oophorectomy. iii. Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy).
• iv. History of bilateral tubal ligation or another surgical sterilization procedure.
• b. Approved methods of birth control are as follows: hormonal contraception (i.e. birth control pills, injection, transdermal patch, vaginal ring, hormonal implant), intrauterine device (IUD), tubal ligation or hysterectomy, subject/partner post-vasectomy, double barrier methods (e.g. condom in combination with spermicide). Abstinence for the duration of the trial and drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control.
