Alternate Title

Cyclophosphamide Plus Bone Marrow Transplantation in Treating Patients With Hematologic Cancer

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase I Treatment Closed 0.5 to 70 NCI JHOC-J9966 JHOC-99110501, NCI-G00-1816, NCT00006042

Objectives

1. Determine the minimum effective dose of pretransplant cyclophosphamide to induce engraftment of haploidentical allogeneic bone marrow without the use of myeloablative conditioning in patients with hematologic malignancies.
2. Determine the incidence and severity of graft versus host disease and nonhematologic toxicities with this treatment regimen in these patients.
3. Correlate the pretreatment phenotypic and functional immunologic characteristics in these patients in relation to risk of graft rejection with this treatment regimen.

Outline

This is a dose-escalation study of cyclophosphamide.

Patients receive fludarabine IV over 1 hour on days -6 to -2; cyclophosphamide IV over 1 hour on days -6, -5, and 3; total body irradiation on day -1; and allogeneic bone marrow transplantation on day 0. Patients also receive tacrolimus IV or orally twice a day on days 4-50; oral mycophenolate mofetil on days 4-35; and filgrastim (G-CSF) subcutaneously or IV starting on day 4 and continuing until blood counts recover.

Cohorts of 3-6 patients receive escalating doses of cyclophosphamide until the minimum effective dose necessary to induce chimerism without unacceptable toxicity in these patients is determined.

Patients are followed at 2 and 6 months, at one year, and then annually thereafter.
