TIL Therapy for Metastatic Renal Cell Carcinoma

• Status: Recruiting
• Trial end date: 2020-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Adoptive T cell therapy (ACT) 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 activation and proliferation in vivo.

Recent studies suggest, that TIL therapy works in other cancers than Metastatic Melanoma, including Renal Cell Carcinoma. In this study TIL therapy is administered to patients with metastatic Renal Cell Carcinoma.
