Active clinical trials for "Fanconi Anemia"

The purpose of this study is to determine the effects of the oral iron chelator Deferasirox on liver iron content after one year of treatment in patients with iron overload from repeated blood transfusions. Beta-thalassemia patients unable to be treated with deferoxamine or patients with rare chronic anemias such as Myelodysplastic Syndrome, Fanconi's Syndrome, Blackfan-Diamond Syndrome, and Pure Red Blood Cell Anemia are eligible for this study. Liver iron content will be measured by liver biopsy at the beginning of the study and after one year of treatment. However, those patients living in the San Francisco/Oakland area may have a SQUID in place of the liver biopsy if the biopsy is not medically possible for them. The SQUID is a non-invasive magnetic means to measure liver iron content.

OBJECTIVES: I. Determine the effectiveness of moderate dose cyclophosphamide and radiotherapy in terms of improving survival and reducing the morbidity following allogeneic bone marrow transplantation in patients with myelodysplastic syndrome and acute leukemia related to Fanconi's anemia.

To evaluate if HLA-mismatched, unrelated-donor umbilical cord blood stem and progenitor cell units (UCBU) offered a clinically acceptable alternative to matched unrelated-donor allogeneic bone marrow for transplantation with 180-day disease free survival as the endpoint. HLA typing was performed using DNA-base high resolution methods to determine HLA alleles. Patients with "true" HLA 3/6 and 4/6 matches were evaluated. In addition, a separate study in adults addressed the problem of limited cell dose and engraftment failure. The study was not planned as a randomized comparative clinical trial. Instead, it is a phase II/III efficacy study.

This observational protocol will allow for an independent, prospective evaluation of the improvement in survival of patients with Fanconi disease in hematological deadlock due to the absence of an HLA-identical donor and having received a haploidentical transplant.

The purpose of this study is to assess the feasibility of Plerixafor used in combination with G-CSF (Granulocyte Colony Stimulating Factor) in 5 Fanconi anemia patients to mobilize and collect a sufficient number of peripheral blood CD34+ cells for peripheral blood apheresis, for further gene therapy study.

This is a single institution, open-label, single arm pilot study of Metformin in patients with Fanconi Anemia (FA) and cytopenias with the primary endpoint of hematologic response. This study will also assess safety, tolerability, and the biologic effects of Metformin in patients with FA.

This clinical trial is studying how well giving fludarabine phosphate and melphalan together with total-body irradiation followed by donor stem cell transplant works in treating patients with hematologic cancer or bone marrow failure disorders. Giving low doses of chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells or abnormal cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect)

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.

The purpose of this research study is to: (1) determine if the combination of low dose total body irradiation, low dose cyclophosphamide and the addition of fludarabine, and a serum to suppress the immune system can allow selected stem cells to take and grow; (2) determine if selected stem cells from the blood or marrow can take and not cause graft-versus-host disease (GvHD), and; (3) evaluate the side effects of the combination of low dose radiation and chemotherapy drugs used for these transplants.

RATIONALE: Giving low doses of chemotherapy before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving immunosuppressive therapy before or after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well chemotherapy followed by donor peripheral stem cell transplant works in treating patients with hematologic cancer or aplastic anemia.
