Adequate end organ function, defined as the following:~   total bilirubin \< 1.5 x ULN, SGOT and SGPT \< 2.5 x UNL, creatinine \< 1.5 x ULN, ANC \> 1.5 x 109/L, platelets \> 100 x 109/L.~6. Female patients of childbearing potential must have negative pregnancy test within 7 days before initiation of study drug dosing. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential.

Patient has a severe and/or uncontrolled medical disease (i.e., uncontrolled diabetes, chronic renal disease, or active uncontrolled infection).~6. Patient has a known brain metastasis. Non-specific CNS changes on MRI/CT characteristic of NF1 are allowed, but not known CNS malignancies.~7. Patient has known chronic liver disease (i.e., chronic active hepatitis, and cirrhosis).~8. Patient has a known diagnosis of human immunodeficiency virus (HIV) infection.~9. Patient received chemotherapy within 4 weeks (6 weeks for nitrosourea or mitomycin-C) prior to study entry, unless the disease is rapidly progressing.~10. Patient previously received radiotherapy to greater than 25 % of the bone marrow~11. Patient had a major surgery within 2 weeks prior to study entry.~12.
