Autologous T Cells 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 12/01/2009)

Autologous T Cells 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 12/01/2009)

A Phase I Dose Escalation Safety and Feasibility Study of WT1-Specific T Cells for the Treatment of Patients With Advanced Ovarian, Primary Peritoneal, and Fallopian Tube Carcinomas

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)

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.

This is a phase I dose escalating trial designed to identify tolerable, clinically active doses of Wilms' tumor gene (WT1) peptide sensitized T cells when administered alone or with nonmyelosuppressive chemotherapy in patients with recurrent or persistent, evaluable WT1+ ovarian, primary peritoneal, or fallopian tube carcinomas.

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.

Obtained prior to adoptive therapy to quantitate baseline levels of WT1 reactive T cells, by quantitation of WT1 specific CTLp by LDA, T cells secreting IFNγ in response to peptide and, in HLA A0201+ patients, T cell binding WT1 peptide HLA A2 tetramers.
