For patients not enrolled in a dose finding portion of the study, concomitant therapy with strong inducers or inhibitors of CYP2D6 or CYP3A4 is STRONGLY discouraged but not prohibited if clinically indicated

- Patients who are currently receiving another investigational drug
- Patients receiving medications for treatment of left ventricular systolic dysfunction
- Patients with Fanconi anemia, Kostmann syndrome, Shwachman syndrome or any other known congenital bone marrow failure syndrome
- Patients with known prior allergy to any of the medications used in protocol therapy
- Patients with documented active, uncontrolled infection at the time of study entry
