NCT00675831

Brief Summary

The purpose of this research study is to evaluate the safety and efficacy of cell depletion in a donor lymphocyte infusion (DLI) product with the use of the CliniMACS machine. Previously, patients with hematologic malignancies who have relapsed after transplant have been given infusions of donor white blood cells calsed donor lymphocyte infusion (DLI) as a way to boost their immune function and fight cancer. Information from other research studies suggests that lowering the number of a certain type of white blood cell called CD25+ Tregs in the DLI may allow for a greater effect. In this research study, we are looking for the appropriate dose of DLI depleted of the CD25+ Treg white blood cells that can be given safely.

Study Arms (1)

CD25+ Treg depleted DLI dose schema

EXPERIMENTAL

Patients will receive a defined dose of CD25+ Treg depleted DLI. 5 patients will be enrolled, initially at dose level B, and subsequent cohorts will be dose adjusted per the CD3+ dose escalation/de-escalation schema: * Dose level -C: 3x10\^7 (CD3+Dose (#cells/kg\*)) * Dose level -B: 1x10\^7 (CD3+Dose (#cells/kg\*)) * Dose level -A: 1x10\^6 (CD3+Dose (#cells/kg\*)) \*Recipient's body weight in Kg

Device: CliniMACS CD25 Reagent Device

Interventions

Used to engineer CD25+ depleted donor lymphocytes which will be infused intravenously over 5-10 minutes

  • At least 2 months following hematopoietic stem cell transplantation
  • Off any systemic immunosuppressive medication for treatment or prevention of GVHD, for a minimum of 2 weeks prior to study entry
  • Recipient with donor chimerism of 20% or greater within 6 weeks prior to DLI
