RATIONALE: Giving low doses of chemotherapy, such as cyclophosphamide, before a donor bone marrow transplant helps stop the growth of abnormal cells. It also stops the patient's immune system from rejecting the donor's bone marrow. The donated bone marrow stem cells may replace the patient's immune system and help destroy any remaining abnormal cells. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and methotrexate before or after transplant may stop this from happening.

PURPOSE: This phase I trial is studying the side effects and best dose of cyclophosphamide in treating patients who are undergoing a donor bone marrow transplant for Fanconi's anemia.

Primary Outcome Measures:
  • Conditioning-related toxicity [ Time Frame: 100 days post-transplant ]
  • Graft rejection [ Time Frame: 100 days post-transplant ]

Enrollment: 25
Study Start Date: June 1998
Primary Completion Date: July 2003 (Final data collection date for primary outcome measure)
Detailed Description:


  • Decrease the conditioning-related toxicity of cyclophosphamide without decreasing the engraftment rate to < 90% in patients undergoing allogeneic bone marrow transplantation for Fanconi's anemia.

OUTLINE: This is a multicenter, dose-finding study of cyclophosphamide.

  • Nonmyeloablative conditioning regimen: Patients receive cyclophosphamide IV on days -5 to -2.

Cohorts of 5-10 patients receive decreasing doses of cyclophosphamide until the optimal dose (OD) is determined. The OD is defined as the dose at which ≥ 4 of 5 patients achieve engraftment and < 1 of 10 patients experiences dose-limiting toxicity.

  • Allogeneic bone marrow transplantation (BMT): Patients undergo allogeneic BMT on day 0.
  • Graft-vs-host-disease (GVHD) prophylaxis: Patients receive cyclosporine orally or IV twice daily beginning on day -1 and continuing until day 49, followed by a taper on days 50-180 in the absence of GVHD. Patients also receive methotrexate IV on days 1, 3, 6, and 11.

After completion of study treatment, patients are followed periodically for 5 years.

PROJECTED ACCRUAL: A total of 27 patients will be accrued for this study.
