TIL Therapy for Metastatic Ovarian Cancer

Adoptive T cell therapy with tumor infiltrating lymphocytes (TIL) has achieved impressive clinical results with durable complete responses in patients with metastatic melanoma. 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 acitivation and proliferation in vivo.

Objectives:

To evaluate safety and feasibility when treating patients with metastatic ovarian cancer with ACT with TILs.

To evaluate treatment related immune responses To evaluate clinical efficacy

Design:

Patients will be screened with a physical exam, medical history, blood samples and ECG.

Patients will undergo surgery to harvest tumor material for TIL production. Patients is admitted day -8 in order to undergo lymphodepleting chemotherapy with cyclophosphamide and fludara starting day -7.

On day 0 patients receive TIL infusion and shortly after starts IL-2 infusion continually following the decrescendo regimen.

The patients will followed until progression or up to 5 years
