Hematopoietic Stem Cell Transplantation in High Risk Patients With Fanconi Anemia

4 de novembro de 2021 atualizado por: Masonic Cancer Center, University of Minnesota

Hematopoietic Stem Cell Transplantation in High Risk Patients With Fanconi Anemia MT2002-02

RATIONALE: A bone marrow or umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Giving combination chemotherapy before a donor stem cell transplant may make the transplant more likely to work. This may be an effective treatment for patients with high risk Fanconi's anemia.

PURPOSE: This clinical trial is studying how well combination chemotherapy works in treating high risk patients who are undergoing a donor stem cell transplant for Fanconi's anemia.

Visão geral do estudo

Descrição detalhada

OBJECTIVES:

Primary

  • Determine whether the incidence of neutrophil engraftment is acceptable in high-risk patients with Fanconi's anemia treated with busulfan, cyclophosphamide, fludarabine, and antithymocyte globulin followed by allogeneic hematopoietic stem cell transplantation.

Secondary

  • Determine the tolerability of mycophenolate mofetil in these patients.
  • Determine the incidence of acute and chronic graft-vs-host disease in patients treated with this regimen.
  • Determine the incidence of major infections in patients with a history of major infections treated with this regimen.
  • Determine the incidence of relapse in patients with refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, or acute myeloid leukemia treated with this regimen
  • Determine the probability of 1-year survival of patients treated with this regimen.

OUTLINE: Patients are stratified according to donor/recipient HLA type (identical vs other).

  • Cytoreductive combination chemotherapy: Patients receive busulfan intravenously (IV) over 2 hours twice daily on days -7 and -6 and cyclophosphamide IV over 2 hours and fludarabine IV over 30 minutes once daily on days -5 to -2.
  • Graft failure prophylaxis: Patients receive methylprednisolone IV twice daily on days -5 to 30 and anti-thymocyte globulin IV over 4-6 hours twice daily on days -5 to -1.
  • Graft-vs-host disease prophylaxis: Patients receive cyclosporine IV over 2 hours twice daily on days -3 to 100 (if patient has a matched sibling donor) or days -3 to 180 (if patient has another donor type). Patients also receive mycophenolate mofetil orally or IV twice daily on days -3 to 45.
  • Allogeneic hematopoietic stem cell transplantation (HSCT): Patients undergo allogeneic HSCT (using bone marrow or umbilical cord blood) on day 0. Patients receive filgrastim (G-CSF) subcutaneously beginning on day 1 and continuing until blood counts recover.

After completion of study treatment, patients are followed periodically for 3 years.

Descrição

Inclusion Criteria:

  • Patients must be <45 years of age with a diagnosis of Fanconi anemia with:

    • Biallelic BRCA2 mutations, or
    • Aplastic anemia, or advanced myelodysplastic syndrome (MDS) (MDS with ≥5% blasts), or acute leukemia who are ineligible for total body irradiation. Aplastic anemia is defined as having at least one of the following (with or without cytogenetic abnormalities): platelet count <20 * 10^9, - absolute neutrophil count (ANC) <5 * 10^8/L, - Hgb <8 g/dL
  • Patients must have an HLA-A, B, DRB1 identical or 1 antigen mismatched related or unrelated BM donor or have an HLA-A, B, DRB1 identical, 1 antigen or 2 antigen mismatched related or unrelated umbilical cord blood (UCB) donor. Patients and donors will be typed for HLA-A and B using serological level typing and for DRB1 using high resolution molecular typing.
  • Adequate major organ function including:

    • Cardiac: ejection fraction >45%
    • Hepatic: no clinical evidence of hepatic failure (e.g. coagulopathy, ascites, no cirrhosis)
    • Karnofsky performance status >70% or Lansky >50%
  • Women of child bearing potential must be using adequate birth control and have a negative pregnancy test.

Exclusion Criteria:

  • Active CNS leukemia at time of HSCT.
  • Active uncontrolled infection within one week of hematopoietic stem cell transplant (HSCT).
  • Pregnant or lactating female.

Donor Inclusion Criteria:

  • Donor must be in good health based on review of systems and results of physical examination.
  • Donor must have a normal hemoglobin, white count, platelet count and partial thromboplastin time (PTT), and a negative diepoxybutane (DEB) test.
  • HIV-NAT negative, HTLV-1, HTLV-2 negative, Hepatitis B and C negative.
  • Female donors of childbearing potential must have a negative pregnancy test.
  • Unrelated donors must agree to peripheral blood stem cell (PBSC) donation

Donor Exclusion Criteria:

  • Donor is a lactating female.
