Age >18 years ECOG performance status <2 Normal Ejection Fraction on ECHO scan Subjects must have normal organ and marrow function as defined below: Absolute neutrophil count >1000/mL Platelets >75,000/mL For subjects with known marrow infiltration, ANC ≥500 and platelets ≥30,000 Total bilirubin <1.5 X institutional upper limit of normal (ULN) (<2X ULN for subjects with Gilbert's syndrome) AST (SGOT) and ALT (SGPT) <3 X institutional ULN (for subjects with hepatic involvement <5 X institutional ULN) PT/INR and aPTT within 1.5 X institutional ULN Creatinine <1.5 X institutional ULN OR Creatinine clearance >60 mL/min/1.73 m2 for subjects with creatinine levels above institutional normal Women of childbearing potential must have had a prior hysterectomy or have a negative serum pregnancy test and be using adequate contraception prior to study entry and must agree to use adequate contraception from study entry through at least 6 months after discontinuation of study drug. Men must also agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and from study entry through at least 6 months after discontinuation of study drug. Should a woman enrolled in the study or a female partner of a man enrolled in the study become pregnant or suspect she is pregnant while participating in this study or within 6 months after discontinuation of study, she should inform the Investigator immediately.

Patients with history of known skin cancers including non-melanotic skin cancers within the past 3 years will not be included in this trial. The following prior malignancies are allowable irrespective of when they occurred: in situ carcinoma of the cervix, in situ ductal breast cancer, and low-grade local bladder cancer.
