  Purpose

The purpose of this research is to explore what we believe may be a safer and more effective means of performing stem cell transplantation in patients with Osteopetrosis, using chemotherapy and radiation designed to bring about engraftment and lessen transplant mortality. Prior multi-institutional data in past studies found that approximately 30% of Osteopetrosis patients do not engraft. Therefore, in this study, we utilize a reduced intensity design of pre-transplant drugs to try to make transplants safer for this disease, as well as to provide a second infusion of stem cells in patients with matched related or unrelated donors.

Arms Assigned Interventions
Active Comparator: Patients with Donor Grafts
This group includes patients that are recipients of unrelated or matched related donor grafts (both peripheral blood and marrow) with a second CD34 cell infusion administered on Day 42.
Procedure: Stem Cell Transplantation
Undergo allogeneic hematopoietic stem cell transplantation using marrow, peripheral blood or cord blood grafts
Other Names:
  • BMT, HSCT, Bone Marrow Transplant
  • UCBT
Drug: Conditioning for transplantation-donor graft
The pre-transplant conditioning will include: Campath-1H, Busulfan, Fludarabine (marrow and peripheral blood)
Other Name: Busulfex, Fludara, Campath
Radiation: Total Lymphoid Irradiation
Dose 500 cGy via anteroposterior (AP) and posteroanterior(PA) fields (250 cGy AP and 250 cGy PA).

Active Comparator: Patients With Cord Blood Transplant
This group includes patients who received cord blood transplants with more intensive chemotherapy regimen.
Procedure: Stem Cell Transplantation
Undergo allogeneic hematopoietic stem cell transplantation using marrow, peripheral blood or cord blood grafts
Other Names:
  • BMT, HSCT, Bone Marrow Transplant
  • UCBT
Radiation: Total Lymphoid Irradiation
Dose 500 cGy via anteroposterior (AP) and posteroanterior(PA) fields (250 cGy AP and 250 cGy PA).
Other Name: TLI
Drug: Conditioning for cord blood transplant
The pre-transplant conditioning will include: Campath-1H, Busulfan, and Cyclophosphamide
Other Name: Busulfex, Campath, Cytoxan

Detailed Description:

This revised transplant protocol will test the following: 1) the ability to achieve engraftment with the reduced intensity protocol and a second infusion of stem cells on day 42, 2) the mortality associated with transplant by day 100, 3) patient outcomes, based on differential imaging and biologic evaluations prior to transplantation and at designated points after transplantation (day 100, 6 months, 1, 2 and 5 years). Additional biologic studies will include microarray analysis, and evaluation of blood parameters and genes that may be important in the disease process. In older patients, studies to evaluation osteoclast differentiation and function will also be offered.

  Eligibility

Ages Eligible for Study:   up to 45 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients eligible for transplantation under this protocol will be < or = 45 years of age, and will be diagnosed with severe osteopetrosis. This will be defined as having the following manifestations of the disease.

    1. Bones that are uniformly markedly dense based on skeletal survey
    2. No history that would suggest autosomal dominant inheritance
    3. Evidence of hematologic changes that are attributed to the underlying disease, including
  • the need for ongoing transfusions, OR
  • the presence of progressive anemia or thrombocytopenia, OR
  • a white blood cell differential with a predominance of immature forms and evidence of extramedullary hematopoiesis, OR
  • persistence of serious infectious complications that are thought to be due to the abnormal architecture of the bone that are resistant to surgical and medical interventions.

Exclusion Criteria:

  • Patients >45 years of age
  • Evidence of hepatic failure
  • Pulmonary dysfunction sufficient to significantly increase the risk of transplant.
  • Renal dysfunction with glomerular filtration rate (GFR) <30% of predicted.
  • Cardiac compromise sufficient to substantially increase the risk of transplantation
  • Severe, stable neurologic impairment.
  • Human immunodeficiency virus (HIV) positivity.
  • Pregnant or lactating females
