T-cell Therapy in Combination With Checkpoint Inhibitors for Patients With Advanced Ovarian-, Fallopian Tube- and Primary Peritoneal Cancer

GY1721

Adoptive T cell therapy (ACT) with tumor infiltrating lymphocytes (TIL) has achieved impressive clinical results with durable complete responses in patients with metastatic melanoma. Recently, the investigators have completed a pilot study treating 6 patients with metastatic ovarian cancer. The TILs are isolated from patients own tumor tissue followed by in vitro expansion and activation for around 4-6 weeks. Before TIL infusion the patients receive 1 week of preconditioning chemotherapy with cyclophosphamide and fludarabine. After TIL infusion Interleukin-2 is administered to support T cell activation and proliferation in vivo. The investigators recent pilot study has shown TIL therapy in patients with metastatic ovarian cancer to be feasible and tolerable. Mainly transient clinical responses where observed and therefore the investigators plan to combine TIL therapy with checkpoint inhibitors to potentially increase the clinical effect.
