  • Patients must have normal organ function as defined in protocol.
  • Ability to understand and willingness to sign a written informed consent and HIPAA consent document

Exclusion

  • Patients may not be receiving any other investigational agents
  • Subjects must not be experiencing toxicity due to prior therapy that has not resolved to ≤Grade 1 by study registration, with the exception of sensory neuropathy related to previous systemic therapy exposure, alopecia and fatigue.
  • Patients that have transformed to Acute Myeloid Leukemia defined by \>20% blasts count on peripheral blood smear or bone marrow biopsy evaluation
  • Uncontrolled inter-current illness including, but not limited to, any other malignancy (with the exception of hormonal therapy for breast cancer/prostate cancer in remission \>1 year and for non-hormonal therapies for other cancers in remission for \>3 years), other ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
