Protocols for Bone Marrow Transplantation in Nonmalignant Hematologic Conditions

Bone marrow failure researchers at the Center for Childhood Cancer Research (CCCR) led by Timothy Olson, MD, PhD, are developing disease-specific treatment protocols in a three-armed umbrella clinical trial. The goal of the trial is to standardize approaches to treatments and to try to minimize treatment toxicity. 

Marrow donors in this trial are siblings. The trial design contains essentially three pretreatment conditioning regimens for patients to undergo transplant based on the categorization of their disease.  

Disease-specific categories are assigned to one of three treatment arms:

  • Patients with aplastic anemia
  • Patients with disease related to DNA repair defects and thus sensitive to the side effects of chemotherapy and radiation
  • Patients who have only one line of bone marrow affected (red blood cells, white blood cells, or platelets)

Targeting each of those populations differently with regard to chemotherapy and radiotherapy will contribute to more successful transplantations. This is a prospective study that will follow patients to two years post transplantation. 

Results from this study will contribute to the development of successful disease-specific bone marrow transplantation protocols.
