    • Hemoglobinopathies (including sickle cell disease and thalassemia

  • Acute leukemias:

    • Acute myeloid leukemia (AML) - antecedent myelodysplastic syndrome, secondary AML, high risk cytogenetic abnormalities or normal cytogenetics with high-risk molecular mutations (including but not limiting to Flt3-ITD mutation)
    • Acute lymphoblastic leukemia (ALL) B cell or T cell

  • Chronic myelocytic leukemia (CML):

    • Chronic phase (intolerant or unresponsive to imatinib and/or tyrosine kinase inhibitors)
    • Second chronic phase or accelerated phase who are ineligible for conventional myeloablative transplantation

  • Myeloproliferative and myelodysplasia syndromes:

    • Myelofibrosis (with/without splenectomy) with intermediate to high risk features
    • Advanced polycythemia vera not responding to therapy
    • Myelodysplastic syndrome (MDS) with an International Prognostic Scoring System (IPSS) score of intermediate or higher
    • Secondary MDS with any IPSS score
    • Chronic myelomonocytic leukemia (CMML)

  • Lymphoproliferative disease:

    • Chronic lymphocytic leukemia (CLL), low-grade non-Hodgkin lymphoma (NHL) (recurrent or persistent) cytotoxic therapy refractory or with less than 6 months duration of complete response (CR) between courses of conventional therapy
    • Multiple myeloma (MM) progressive disease after auto bone marrow transplantation (BMT), tandem allo after prior auto
    • Waldenstrom?s macroglobulinemia (failed one standard regimen)
    • T or B cell lymphoma with poor risk features

    • Hodgkin disease:

      • Received and failed frontline therapy
      • Failed or not eligible for autologous transplantation

• Suitable related haploidentical donor identified:

  • Must be matched at least at 5 of 10 HLA antigens (A, B, C,DRB1, DQ)
  • Must not be matched at more than 7 of 10 HLA antigens
  • Recipient should not have HLA antibodies to potential donor; if the recipient does have HLA antibodies to the potential donor, an alternative donor is preferred; however, if there are no suitable alternative donors, the donor to whom the patient has HLA antibodies can be utilized as long as the antibody titer is less than 2000 median fluorescence intensity (MFI); if the titer is > or = to 2000 MFI, the recipient must undergo successful antibody desensitization prior to enrollment on this study; any patients who have demonstrated donor specific antibodies will not be evaluated for the end points measured in this study but will be followed for treatment related toxicities
  • Haploidentical donors that are ABO compatible with the recipient are preferred. Minor ABO incompatibility is preferred to major ABO incompatibility. Major ABO incompatibility between recipient and donor is the least preferred but still acceptable for this study.
  • It is preferred that the haploidentical donor must be available to donate on day -1 and day 0, so that fresh product can be processed by the Stem Cell lab and administered to the patient on day 0.. While less preferable, cryopreserved product may be utilized with this product.
• Diffusing capacity of the lung for carbon monoxide (DLCO) > 40% predicted, corrected for hemoglobin and/or alveolar ventilation
• Left ventricular ejection fraction > 40%
• Bilirubin, liver alkaline phosphatase, serum glutamic-oxaloacetic transaminase (SGOT) or serum glutamate pyruvate transaminase (SGPT) =< 3 x upper limit of normal
• Calculated creatinine clearance > 40 cc/min by the modified Cockcroft-Gault formula for adults or the Schwartz formula for pediatrics
• Have a Karnofsky (adult) or Lansky (for =< 16 years) performance status >= 60%
• Patient must be able to pass radiation evaluation (i.e.: able to receive 200 cGy)
• Patients who have failed a prior autologous transplant are eligible; however, at least 90 days must have elapsed between the start of this reduced intensity conditioning regimen and the last transplant if patient had a prior autologous BMT
• Participants of child-bearing potential must agree to use adequate contraceptive methods (e.g., hormonal or barrier method of birth control; abstinence) prior to study entry; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
• Participant or legal representative must understand the investigational nature of this study and sign an independent ethics committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure
• Patient in CR or has a bone marrow failure disorder or non-malignant hematologic or immune disorder : does NOT have a sibling donor or 12/12 HLA matched unrelated donor available OR treating clinician considers haploidentical transplant referable (despite sibling donor availability or 12/12 HLA matched donor availability) due to patient's clinical status.
• Exclusion Criteria:
• Participants who have had chemotherapy, radiation treatment and/or surgery 2 weeks prior to entering the study or, as per discretion of the treating physician, those who have not recovered sufficiently from adverse events due to agents administered more than 2 weeks earlier
• Uncontrolled central nervous system (CNS) disease (for hematologic malignancies)
• Child-Pugh class B and C liver failure
• Concomitant active malignancy that would be expected to require chemotherapy within 3 years of transplant (other than non-melanoma skin cancer)
• Patients who have received maximally allowed doses (given in 2 Gy fractionations, or equivalent) of previous radiation therapy to various organs; patients who previously have received a higher than allowed dose of radiation to a small lung, liver and brain volume, will be evaluated by the radiation oncologist to determine if the patient is eligible for study
• Uncontrolled diabetes mellitus, cardiovascular disease, active serious infection or other condition which, in the opinion of treating physician, would make this protocol unreasonably hazardous for the patient
• Known human immunodeficiency virus (HIV) positive
• Pregnant or nursing female participants
• Patients who in the opinion of the treating physician are unlikely to comply with the restrictions of allogeneic stem cell transplantation based on formal psychosocial screening
• Patients with donor specific HLA antibodies with a titer greater than 2000 MFI (whether or not they have undergone a desensitization protocol)
• Patients who have undergone a prior allogeneic hematopoietic or (other organ) transplant
• Treating physician considers the potential HLA haploidentical donor to be ineligible to receive G-CSF, and/or concern on the part of the treating physician for risk of harm to the potential donor with administration of G-CSF, and/or refusal by the potential donor (or donor?s guardian) to receive G-CSF
• Any condition which in the investigator?s opinion deems the participant an unsuitable candidate to receive study drug
• Received an investigational agent within 30 days prior to enrollment
