Summary

The purpose of this study is to determine the ability of a donor lymphocyte infusion (DLI) given with methotrexate to hasten immune recovery without causing severe graft-versus-host disease (GVHD) in recipients who have had a T-cell depleted transplant.

Detailed description

Studies have shown that giving donor T cells after a mismatched T cell-depleted stem cell transplant can speed up recovery of T cells in the patient. This approach can cause severe graft versus host disease (GVHD). The purpose of this study is to determine whether giving a donor lymphocyte infusion (DLI) with methotrexate can accelerate immune recovery in recipients of T cell-depleted stem cell transplants. Thirty days after a T-cell depleted transplant, patients will be given a DLI. They will be monitored for immune recovery as measured by CD4 count and for GVHD toxicity. Patients will be separated into six cohorts based on dose of DLI received: 3 x 10\^4, 4 x 10\^4, 5 x 10\^4, 6 X 10\^4, 8 x 10\^4, and 10 X10\^4 cells/ kg of body weight. A minimum of 3 patients will be tested at each dose starting with the lowest dose. Dose escalation will continue until the dose associated with CD4 count \>100 at Day +120 after transplant without significant GVHD is determined. All patients will receive thirteen doses of methotrexate after the DLI to prevent GVHD. Patients will be followed for 2 years for outcomes.

Type	Name	Description
BIOLOGICAL	Infusion of donor lymphocytes	A donor lymphocyte infusion will be given to provide T cells. There will be a dose escalation: 3 x 10\^4, 4 x 10\^4, 5 x 10\^4, 6 X 10\^4, 8 x 10\^4, and 10 X10\^4 cells/kg body weight. At least three patients will be assessed at each dose to determine safety before dose is increased.
