filgrastim
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.
therapeutic autologous lymphocytes
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.
cyclophosphamide
Patients enrolled in dose levels II and III also undergo pre-infusion lymphodepletive conditioning comprising cyclophosphamide IV on day -2
laboratory biomarker analysis
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.
