Brief Summary
This study will evaluate the safety and effectiveness of treating patients with severe aplastic anemia (SAA) or myelodysplastic syndrome (MDS) with both peripheral blood stem cells from a family member and umbilical cord blood stem cells from an unrelated donor. Patients with SAA or MDS for whom other treatments have failed or are not available may be eligible for this study. Candidates may not have a tissue-matched sibling or matched unrelated donor and must have a family member who is a partial tissue type match. Participants undergo the following tests and procedures:
- Insertion of a central intravenous (IV) line (plastic tube) into a large vein. The tube is used for giving the donated stem cells and antibiotics and other medicines, for transfusions of red blood cells and platelets, and for collecting blood samples.
- Preparatory chemotherapy (fludarabine, cyclophosphamide and anti-thymocyte globulin) and total body irradiation to suppress immunity and prevent rejection of the donated cells.
- Infusion of the donated stem cells and umbilical cord cells.
- Immune suppression with the drugs tacrolimus, mycophenolate mofetil and prednisone to prevent rejection of the donated cells and to prevent graft-versus-host disease (GVHD), a complication of stem cell transplants in which the donors immune cells destroy the patients healthy tissues. The average hospital stay after stem cell transplantation is 3 to 4 weeks. Patients return for frequent follow-up visits for the first 2 to 4 months after transplantation. Once the patient returns home, his or her referring physician is asked to send results of any laboratory testing to the NIH researchers at least every 3 months for the first 3 years and annually thereafter. Patient follow-up visits are scheduled at NIH at 1, 2, 3, 4 and 5 years after transplantation to monitor for signs of disease or post-transplantation complications, such as infection or GVHD. After 5 years, participants are offered the opportunity to enroll in NHLBIs long-term evaluation and follow-up care protocol.

Co-infusion of UCB and Haploidentical CD34+ cells
EXPERIMENTALStem cell recipients received co-infusion of unrelated umbilical cord blood (UCB) and haploidentical CD34+ cells from a related donor following non-myeloablative conditioning for neutropenic patients with severe aplastic anemia (SAA) or myelodysplastic syndrome (MDS) with refractory anemia (RA)
Interventions
unrelated umbilical cord blood will be co-infused with haploidentical CD34-selected cells from a related donor for treatment of severe aplastic anemia and myelodysplastic syndrome.
Eligibility Criteria
You may qualify if:
- Diagnosed with severe aplastic anemia characterized by all of the following:
- Bone marrow cellularity less than 30 percent (excluding lymphocytes)
- Transfusion dependence for platelets and/or red blood cells (RBCs)
- Neutropenia (absolute neutrophil count less than 500 cells/microL) OR for patients receiving granulocyte transfusions, absolute neutrophil count \< 500 cells/microL before beginning granulocyte transfusions\].)
- Diagnosed with myelodysplastic syndrome characterized by refractory anemia OR refractory anemia with ringed sideroblasts (RARS and at least one of the following:
- Neutropenia \[(absolute neutrophil count \< 500 cells/microL) OR for patients receiving granulocyte transfusions, absolute neutrophil count \< 500 cells/microL before beginning granulocyte transfusions\]) and history of 1 or more opportunistic infections related to neutropenia. OR
- History of severe aplastic anemia transformed to MDS
- Intolerance of or failure to respond standard immunosuppressive therapy.
- Availability of at least one HLA-haploidentical (i.e. greater than or equal to 5/10 and less than or equal to 8/10 HLA match) related donor (HLA-A, B, C, DR, and DO loci) who is available to donate CD34+ cells (4-75 years old).
- Availability of at least one 4/6 HLA-matched (HLA-A, B, and DR loci) cord blood unit from the National Marrow Donor Program (NMDP). The cord blood unit must contain a minimum total nucleated cells (TNC) (prior to thawing) of at least 1.5 x 10(7) cells per kilogram of recipient body weight with the following exception: if the minimum criterion of TNC is not met the cord unit must contain at least 1.7 x 10(5) CD34 plus cells/kg (prior to thawing).
- Ages 4-55 years inclusive.
- Ability to comprehend the investigational nature of the study and provide informed consent. The procedure will be explained to subjects aged 4-17 years with formal consent being obtained from parents or legal guardian.
- Telomere Length Testing
- In patients where a suspicion for a familial bone marrow failure syndromes (BMFS) exists, TERC and TERT mutation testing will be performed on protocol 04-H-0012 or performed elsewhere prior to enrolling on 04-H-0012.
You may not qualify if:
- Availability of an HLA identical or 9/10 HLA matched(HLA A, B, C, DR, and DO loci-relative to serve as a stem cell donor.
- The patient is deemed to be a candidate for a 6/6 HLA matched unrelated stem cell transplant (availability of a donor and resources required for such a transplant).
- Eastern Cooperative Oncology Group (ECOG) performance status of 2 or more.
- Major anticipated illness or organ failure incompatible with survival from transplant
- Severe psychiatric illness. Mental deficiency sufficiently severe as to make compliance with the transplant treatment unlikely and making informed consent impossible.
- Positive pregnancy test for women of childbearing age.
- HIV positive
- Diagnosis of Fanconi anemia (by chromosome breakage study).
- Diffusion capacity of carbon monoxide (DLCO) less than 40 percent using DLCO corrected for Hgb or lung volumes (patients under the age of 10 may be excluded from this criterion if they have difficulty performing the test correctly and thus are unable to have their DLCO assessed) using DL Adj and DL/VA/Adj.
- Left ventricular ejection fraction less than 40 percent (evaluated by ECHO)
- Transaminases greater than 5x upper limit of normal (when transaminases are elevated, the subject may be excluded at the discretion of the PI).
- Serum bilirubin greater than 4 mg/dl
- Creatinine clearance less than 50 cc/min by 24 hr urine collection (adjusted for body surface area, i.e.50 ml/min/1.73m(2))
- Serum creatinine \> 2.5 mg/dl
- Failure to collect an adequate number of CD34+ cells (i.e. greater than or equal 2 x 10(6) CD34+ cells/kg) for transplantation from the subject s haploidentical relative.
