Alpha/Beta T Cell Depleted Stem Cell Transplant in Treating Patients with Fanconi Anemia or Telomere Biology Disorder

Trial Status: active

This phase II trial studies how well alpha/beta T cell depleted stem cell transplant works in treating patients with Fanconi anemia or telomere biology disorder . Fanconi anemia and telomere biology disorder are inherited disorders that causes the bone marrow to stop making enough new blood cells (bone marrow failure) or to make abnormal cells (myelodysplastic syndrome or acute leukemia) and the only proven cure is a stem cell transplant. A common risk with a stem cell transplant is graft-versus-host disease (GVHD) which occurs when the donor cells (the graft) see the patient’s body (the host) as foreign and attack it. A method to decrease the risk of GVHD, is to remove most of the lymphocytes, a type of white blood cells, from the donor cell product. There has been a new machine developed which better selects the types of white blood cells to remove from the donor. This type of processing is called T cell receptor (TCR) alpha/beta T cell depletion. The purpose of this study is to learn if removing the donor T cells from the donor product using this new method will be a better way to reduce the risk of GVHD. The benefit of removing these cells with this new method is that they will prevent GVHD without requiring drugs to suppress the immune system. Potentially, the immune system will recover from the transplant faster, which in turn will also lessen the risk of severe infections.
