Cyclophosphamide Plus T-Cell Transplantation for Patients With Hematologic Malignancies

Phase 1
Terminated
Conditions
Leukemia
Myelodysplastic Syndromes
Interventions
Drug: Cyclophosphamide
Biological: Donor T cells
Registration Number
NCT00356928
Lead Sponsor
Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins
Brief Summary

RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of abnormal blood cells, either by killing the cells or by stopping them from dividing. Giving cyclophosphamide together with donor lymphocytes that have been treated in the laboratory may be an effective treatment for myelodysplastic syndromes or myeloproliferative disorders.

PURPOSE: This clinical trial is studying the best dose of donor lymphocytes when given together with cyclophosphamide in treating patients with myelodysplastic syndromes or myeloproliferative disorders.

Detailed Description

OBJECTIVES:

* Determine the maximum tolerated dose of allogeneic CD8-positive T-cell-depleted, haploidentical donor lymphocytes when given after cyclophosphamide in patients with myelodysplastic syndromes or myeloproliferative disorders.

OUTLINE: Patients receive cyclophosphamide on days 1 and 2. Patients then undergo infusion of allogeneic T-cell depleted donor lymphocytes on day 3.

Cohorts of patients receive escalating doses of CD8-positive T-cell-depleted haploidentical donor lymphocytes until the maximum tolerated dose is determined.

PROJECTED ACCRUAL: A total of 44 patients will be accrued for this study.
