• Serum bilirubin =< 1.5 x upper limit of normal (ULN)

• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 2.5 x ULN

• Female patients of childbearing potential must have a negative serum pregnancy test within 2 weeks prior to enrollment

• Male and female patients should use an effective contraceptive method during the study and for a minimum of 6 months after study treatment

Exclusion Criteria:

• Patients with acute promyelocytic leukemia (APL)

• Use of investigational agents within 30 days or any anticancer therapy within 2 weeks before study entry with the exception of hydroxyurea; the patient must have recovered from all acute toxicities from any previous therapy

• Have any other severe concurrent disease, or have a history of serious organ dysfunction or disease involving the heart, kidney, liver, or other organ system that may place the patient at undue risk to undergo treatment

• Patients with a systemic fungal, bacterial, viral, or other infection not controlled (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment)

• Pregnant or lactating patients

• Any significant concurrent disease, illness, or psychiatric disorder that would compromise patient safety or compliance, interfere with consent, study participation, follow up, or interpretation of study results

• Have had a diagnosis of another malignancy, unless the patient has been disease free for at least 3 years following the completion of curative intent therapy including the following:

• Patients with treated non-melanoma skin cancer, in situ carcinoma, or cervical intraepithelial neoplasia, regardless of the disease-free duration, are eligible for this study if definitive treatment for the condition has been completed.

• Patients with organ-confined prostate cancer with no evidence of recurrent or progressive disease based on prostate-specific antigen (PSA) values are also eligible for this study if hormonal therapy has been initiated, or a radical prostatectomy or definitive radiotherapy has been performed

• Have currently active gastrointestinal disease, or prior surgery that may affect the ability of the patient to absorb oral clofarabine
