Infusion of Activated & Expanded Autologous T Cells

Mark Frohlich, MD

Patients will have immune cells collected and then expanded outside of the body. Patients will receive an infusion of a large number of expanded immune cells. There will be three dose levels studied. The goal of the study will be to determine the safety as well as potential efficacy of this treatment.

This is a Phase I/II single arm dose escalation study of a novel T cell immunotherapy for chronic lymphocytic leukemia (CLL). Patients will receive one dose of Xcellerated T Cells(tm), an ex vivo activated and expanded autologous T cell product, in an attempt to enhance immune responses with anti-tumor activity. This study is being conducted to test the safety and determine the maximum tolerated dose (MTD) of Xcellerated T Cells in patients with CLL. In addition, lymphocyte counts, lymph node area, and quantitative immunoglobulins will be assessed for preliminary evidence of a therapeutic effect. In correlative studies, changes in the phenotype of T and B lymphocytes will be evaluated by flow cytometry. Changes in T cell repertoire and anti-tumor immune activity will also be assessed. It is expected that 12 to 18 patients will be treated.

Patients will have immune cells collected and then expanded outside of the body. Patients will undergo standard treatment with high dose chemotherapy followed by peripheral blood stem cell transplantation. Three days following the transplant, patients will receive an infusion of a large number of expanded immune cells. The goal of the study will be to determine the safety as well as potential efficacy of this treatment.

This Phase I/II clinical study is designed to examine the safety of Xcellerated T Cells, an activated, autologous T cell product, in study subjects undergoing an autologous peripheral blood stem cell transplant for the treatment of multiple myeloma. Thirty-five patients will be treated. Patients must have undergone induction therapy prior to study registration, and may not have progressed following induction therapy or any other prior therapy for myeloma.

Patients will undergo a steady state leukapheresis (Xcellerate Leukapheresis) to obtain peripheral blood mononuclear cells that will be used to produce Xcellerated T Cells. During the Xcellerate Process, T cells will be activated and expanded ex vivo by co-stimulation with anti-CD3 and anti-CD28 monoclonal antibodies covalently attached to super-paramagnetic microbeads. While the Xcellerated T Cells are being produced at Xcyte Therapies, patients will be treated with a standard mobilization regimen consisting of cyclophosphamide and filgrastim (Neupogen; G-CSF), followed by a second leukapheresis for collection of peripheral blood stem cells. Patients will be treated with a standard high-dose chemotherapy regimen for multiple myeloma consisting of single agent melphalan (200mg/m2). Patients will then receive their peripheral blood stem cells followed by post-transplant filgrastim for neutrophil recovery. Three days (Day 3) following stem cell infusion, patients will receive a single dose Xcellerated T Cells.
