Trial summary

This study is for patients with Severe Aplastic Anemia (SAA). A stem cell transplant from a genetically matched sibling donor can help or cure this disease in 85 to 100 percent of patients. Stem cells are immature blood cells that grow to become red blood cells, white blood cells or platelets. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 21 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Age < 21 years
  • Diagnosis of severe aplastic anemia. (As defined by at least 2 of the following: ANC < 500/μl, platelet count < 20,000/μl, and a reticulocyte count < 1% after correction for the hematocrit. In addition, the diagnostic bone marrow biopsy must contain less than 25% of the normal cellularity).
  • Patient must have failed one or more courses of immunosuppressive therapy that included ATG. As immunosuppression may take up to 6 months to demonstrate a response, patients must have been observed to have failed immunosuppression for a minimum of six months.
  • Absence of suitable HLA-matched sibling donor.
  • Negative serum pregnancy test for females with child bearing potential.
  • Patient/parent/guardian is able to provide informed consent.

Who cannot join

  • Patients with a life expectancy < 6 weeks.
  • Patients with severe renal disease (creatinine clearance < 40cc/min/1.73m2)
  • Patients with pre-existing severe restrictive pulmonary disease (FVC <40% of predicted)

About this study

This study is for patients with Severe Aplastic Anemia (SAA). A stem cell transplant from a genetically matched sibling donor can help or cure this disease in 85 to 100 percent of patients. Stem cells are immature blood cells that grow to become red blood cells, white blood cells or platelets. A genetic "match" means a brother or sister has same immune type (HLA type) as the patient. Unfortunately, few patients have a matched sibling donor. The chance of negative outcomes is much higher with other types of donors.

This study will test the success of a new approach to stem cell transplant for SAA. Patients in this study will receive drugs and radiation treatment to destroy their diseased bone marrow and to prepare them for stem cell transplant. Bone marrow is the tissue inside the bones where stem cells are made.Stem cells will be harvested from the blood or bone marrow of genetically matched unrelated donors or partially matched family donors. The stem cells will be filtered using a new device that is currently under study. The patients will receive large doses of the filtered stem cells (stem cell graft). Researchers want to find out how the study treatment affects patients, the disease, and the chances for survival.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Allogeneic stem cell transplantProcedure or surgery

  • Fludarabine, CyclophosphamideDrug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To learn the safety of stem cell transplantation in patients with unrelated donors or partially matched family donors

  2. To study the effects (good and bad) of this treatment on the patients, the aplastic anemia, and survival

  3. To learn how well the donor bone marrow grows in patients who receive the research treatment

  4. To learn how many patients need extra T-cells or extra stem cells from the donor to help the donor's blood stem cells grow
