Specialized Blood Cell Transplants for Cancers of the Blood and Bone Marrow

• INCLUSION CRITERIA - Recipients:

Group A: Subjects at high risk for transplant related complications and mortality as defined below:

Ages 10 to 75 (both inclusive) with a history of one of the following:

• Treatment with dose intensive chemotherapy and/or radiotherapy
• Previous history of allo/auto transplant
• History of multiple myeloma or extramedullary plasmacytoma
• Chronic disease or co-morbid medical condition including subjects with symptoms or signs of significant pulmonary disease, hepatic disease, kidney disease, cardiac disease or disease of other organ systems which would result in increased risk of morbidity or death from a standard myeloablative transplant.

Diseases to be included:

• CML chronic phase
• Acute lymphoblastic leukemia (ALL), all subjects in complete or partial remission.
• AML: AML in first complete or partial remission Exceptions: AML with good risk karyotypes: AML M3 t(15:17), AML M4Eo (inv. 16), AML t(8;21). All AML in second or subsequent complete remission.
• MDS: refractory anemia with excess blasts (RAEB), or chronic myelomonocyte leukemia (CMML).
• Myeloproliferative diseases associated with either cytopenia or uncontrolled proliferation.
• CLL or small lymphocytic lymphoma (SLL) with bulky or progressive disease despite prior treatment with chemotherapy which includes purine analogs.
• NHL

A) Intermediate or high grade relapsed or progressive despite treatment with standard therapy ineligible for autologous PBSC transplant.

B) NHL intermediate or high grade relapsing despite prior autologous transplant.

C) Low grade follicular or small lymphocytic lymphoma (1) high risk patients who have relapsed following conventional chemotherapy, (2) relapsed following autologous marrow or PBSC transplant, or (3) chemo resistant disease.

D) Mantle cell lymphoma

E) NHL intermediate or high grade with concurrent BCL2 and MYC translocations who are at high risk for relapsed and who have low survival with conventional chemotherapy.

• HD, relapsed after prior autologous transplant or after 2 or more combination chemotherapy regimens and ineligible for autologous PBSC transplant.
• EBV driven lymphoproliferative disorders progressing despite standard therapies.
• MM: MM subjects must be between the ages of 8 and 65 (both inclusive)
• Mycosis fungoides, which has been shown to be amenable to allogeneic stem cell transplants.

Group B: (Closed to enrollment Oct 2010) Subjects with hematologic diseases associated with reasonable longevity, shown to be curable by allogeneic BMT but where concern for a high procedural mortality with conventional BMT may delay or prevent such treatment.

Ages 8 to 80 (both inclusive) with a history of one of the following

• PNH associated with either life-threatening thrombosis, cytopenia, transfusion dependence or recurrent and debilitating hemolytic crisis.
• Aplastic anemia or PRCA (acquired or congenital) in subjects associated with transfusion dependence and/or neutropenia who are not candidates for or who have failed immunosuppressive therapy
• RA or RARS MDS subjects who have associated transfusion dependence and/or neutropenia.

Ability to comprehend the investigational nature of the study and provide informed consent. The procedure will be explained to subjects age 8-17 years with formal consent being obtained from parents or legal guardian.
