DCVax-L Vaccination With CD3/CD28 Costimulated Autologous T-Cells for Recurrent Ovarian or Primary Peritoneal Cancer

Summary

Subjects with recurrent epithelial ovarian carcinoma or primary peritoneal cancer, who have previously undergone vaccination in clinical study UPCC-11807 with DCVax-L, an autologous vaccine with DC loaded in vitro with autologous tumor lysate. Phase I Subjects enrolled in this study will receive leukapheresis; followed by cyclophosphamide/fludarabine-induced lymphodepletion; followed by adoptive transfer of ex vivo CD3/CD28-costimulated vaccine-primed peripheral blood autologous T cells; followed by a single DCVax-L vaccination, to establish feasibility and safety of this approach. Primary Objectives of Phase I To determine the feasibility and safety of administering vaccine-primed, ex vivo CD3/CD28-costimulated autologous peripheral blood T cells in combination with DCVax-L vaccination, following lymphodepletion with high dose cyclophosphamide/fludarabine. Phase II Twenty-two additional subjects will be randomized to receive either: * ARM-IIA: maintenance DCVax-L vaccination, in combination with oral metronomic cyclophosphamide, or * ARM-IIB: leukapheresis, followed by cyclophosphamide/fludarabine-induced lymphodepletion, followed by adoptive transfer of ex vivo CD3/CD28-costimulated vaccine-primed peripheral blood autologous T cells, followed by maintenance DCVax-L vaccination, plus oral metronomic cyclophosphamide. Primary Objective of Phase II To assess the distribution of progression-free survival at 6 months for patients treated with maintenance DCVax-L vaccination plus oral metronomic cyclophosphamide as well as patients treated with ex vivo CD3/CD28-costimulated vaccine-primed peripheral blood autologous T cells after lymphodepletion with high dose cyclophosphamide / fludarabine, followed by DCVax-L boost vaccination and metronomic oral cyclophosphamide.
