Clinical Trial Summary
RATIONALE: Giving colony-stimulating factors, such as G-CSF, helps stem cells move from the
bone marrow to the blood so they can be collected. Treating stem cells collected from the
patient's blood in the laboratory may increase the number of immune cells that can mount an
immune response against the tumor. The treated stem cells may help destroy any remaining
tumor cells (graft-versus-tumor effect). Chemotherapy may also be given to the patient to
prepare the bone marrow for the stem cell transplant.
PURPOSE: This phase I trial is studying the side effects and best dose of autologous T cells
when given with or without cyclophosphamide and fludarabine in treating patients with
recurrent or persistent advanced ovarian epithelial cancer, primary peritoneal cavity cancer,
or fallopian tube cancer. (fludarabine treatment closed as of 12/012009)
Description:
OBJECTIVES:
- To assess the safety and tolerability of in vitro expanded autologous WT1 specific T
cells, when administered alone or in combination with non-myeloablative,
immunosuppressive conditioning, in patients with recurrent or persistent, advanced,
WT1-positive, ovarian epithelial cancer, primary peritoneal cavity cancer, or fallopian
tube cancer.
- To determine the maximum tolerated dose of autologous WT1 specific T cells in these
patients.
- To quantitate alterations in the concentration of WT1 specific T cells in the blood at
defined intervals post infusion with or without non-myeloablative, immunosuppressive
conditioning in order to gain estimates regarding their survival and proliferation.
- To assess the effects of the adoptively transferred T cells on the growth and
progression of advanced ovarian epithelial cancer, primary peritoneal cavity cancer, or
fallopian tube cancer.
OUTLINE: This is a dose-escalation study of WT1 peptide-specific T cells.
- T-cell generation and isolation: Patients undergo collection of peripheral blood stem
cells (PBMC) from which T cells are purified, stimulated in vitro with WT1
peptide-pulsed autologous EBV BLCL, and expanded ex vivo.
- Stem cell mobilization and harvest: Patients receive filgrastim (G-CSF) subcutaneously
daily for five days. PBMC are collected by leukapheresis on the fifth day and then
cryopreserved for subsequent reinfusion into the patient, in the event of prolonged
cytopenia.
- Autologous T-cell infusion with or without conditioning chemotherapy ( fludarabine
treatment closed as of 12/01/2009): Approximately 4-6 weeks after T-cell sensitization,
patients receive an infusion of autologous WT1-specific T cells over 5-10 minutes on day
0. Patients enrolled in dose levels II and III also undergo pre-infusion lymphodepletive
conditioning comprising cyclophosphamide IV on day -2 and fludarabine phosphate IV over
approximately 30 minutes on days -6 to -2. After a 48-hour rest period, patients receive
autologous WT1-specific T cells. Treatment repeats every 14 days for up to 4 courses in
the absence of disease progression or unacceptable toxicity. Patients with responsive or
stable disease after completion of therapy, may receive additional courses of autologous
WT1-specific T cells every 14 days.
Blood samples are obtained at baseline and periodically during study and assayed for
alterations in circulating levels of WT1 peptide-specific T cells, for biochemical indices of
tumor burden, and for radiologic evidence of tumor response. Serum CA125 levels are measured
and the number of T cells generating interferon gamma in response to autologous EBV BLCL is
quantitated.
After completion of study therapy, patients are followed for up to 12 weeks.
