Induction of Mixed Hematopoietic Chimerism in Patients Using Fludarabine, Low Dose TBI, PBSC Infusion and Post-Transplant Immunosuppression With Cyclosporine and Mycophenolate Mofetil
OBJECTIVES: I. Determine the risk of graft rejection associated with the addition of
fludarabine to a nonmyeloablative conditioning regimen in patients with malignancies
treatable by allogeneic bone marrow (stem cell) transplantation. II. Compare the rate of
graft rejection in patients treated with this regimen vs patients previously untreated with
fludarabine. III. Determine the rate of acute grade II/IV graft versus host disease (GVHD)
and chronic GVHD in these patients treated with fludarabine, low dose total body
irradiation, and allogeneic peripheral blood stem cell transplantation followed by
immunosuppression with cyclosporine and mycophenolate mofetil.
OUTLINE: This is a multicenter study. Patients receive fludarabine IV on days -4 to -2, and
total body irradiation followed by filgrastim (G-CSF) mobilized allogeneic peripheral blood
stem cell transplantation on day 0. Patients also receive oral cyclosporine twice daily on
days -3 to 56 and oral mycophenolate mofetil twice daily on days 0 to 27. Following
completion of immunosuppression therapy patients with stable mixed chimerism and no evidence
of graft versus host disease (GVHD) receive donor lymphocytes IV over 30 minutes on or after
day 65. Treatment repeats every 65 days for up to 6 courses in the absence of disease
progression or unacceptable toxicity. Patients are followed weekly until day 90 after last
lymphocyte infusion, at 4, 6, 12, 18, and 24 months, and then annually thereafter.
PROJECTED ACCRUAL: A total of 75 patients will be accrued for this study within 2 years.
