Cytokine Induced Killer Cells as Post-Transplant Immunotherapy Following Allogeneic Hematopoietic Cell Transplantation
Study Details
Study Description
Brief Summary
The purpose of the study is to determine if the use of activated T cells can effectively treat relapsed disease following allogeneic hematopoietic cell transplantation without causing GVHD.

Experimental: Cytokine-induced Killer Cells The first cohort =1X10 7 cf expanded cells/kg. The second cohort = 5x10 7 expanded cells/kg. The second cohort = 1X10 8 expanded cells/kg. |
Drug: Cytokine Induced Killer Cells
CIK cell dose escalation will be performed in cohorts of three patients per group. The initial dose utilized will be 1x107 expanded cells/kg. Previously, unmanipulated donor lymphocytes administered at this dose did not result in significant GVHD 7. The expansion of the CIK cell population is expected to diminish the T cell subsets responsible for GVHD further reducing the risk of GVHD to recipients. The dose will be increased to 5x107 expanded cells/kg and 1x108 expanded cells/kg in successive escalations based on no significant infusional toxicity or GVHD in the recipients

Outcome Measures
Primary Outcome Measures
- To determine the feasibility of expanding allogeneic cytokine induced killer cells suitable for clinical application using a continuous perfusion culture system. [21 to 28days before infusion]
- To determine the infusional toxicity of ex vivo expanded allogeneic CIK cells in patients with recurrent or refractory disease following allogeneic hematopoietic cell transplantation. [day of infusion up to 24 hours after infusion]
- To determine the incidence of Graft-versus-Host Disease (GVHD) following infusion of allogeneic CIK cells. [first 100 days after infusion]
- To determine the maximum tolerated dose (MTD) of expanded CIK cells for infusion. [day plus 100 after infusion]
Secondary Outcome Measures
- o determine the incidence of disease response following treatment with allogeneic CIK cells. [one year]
- To assess donor-specific chimerism before and after treatment with allogeneic CIK cells. [3 months]
- To optimize the ex vivo expansion of CIK cells using a continuous perfusion culture system. [21-28 days]
