Chronic Myelogenous Leukemia: Chronic myelogenous leukemia in chronic phase, resistant or intolerant to available tyrosine kinase inhibitors; Chronic myelogenous leukemia in accelerated phase; Chronic myelogenous leukemia with blast crisis that has entered into a second chronic phase following induction chemotherapy
  2. Acute Myelogenous Leukemia in first or greater remission
  3. Myelodysplastic Syndrome at least one of the following: treatment-related; monosmy 7, complex cytogenetics or other high risk karyotype; IPSS score of 1.0 or greater; neutropenia or cytopenia requiring transfusion not responding to therapy; peripheral or BM blast count of <10%; CMML
  4. Acute lymphocytic leukemia/lymphoblastic lymphoma: 2nd or subsequent complete remission; first complete remission; marrow blasts <5%, but persistence of minimal residual disease by flow cytometry, cytogenetics, or FISH
  5. Chronic Lymphocytic Leukemia/Prolymphocytic Leukemia: previously treated disease that has either relapsed or failed to respond adequately to conventional-dose therapy including purine analogs
  6. Hodgkin's or Non-Hodgkin's Lymphoma (including low-grade, mantle cell, and intermediate-grade/diffuse): previously treated disease that has either relapsed or failed to respond adequately to conventional-dose therapy or autologous transplantation
  7. Myeloproliferative diseases (myelofibrosis, CMML)
