Tumor-infiltrating lymphocytes glowing with tumor focused in the center

Welcome to the TIL Cell Therapy Working Group

The TlL Working Group is a team of internationally-recognized oncologists dedicated to helping healthcare practitioners better understand TIL cell therapy. TIL cell therapy is a type of cell therapy in which tumor-infiltrating lymphocytes are harvested from a patient’s tumor and grown in large numbers in vitro. These lymphocytes are then given back to the patient by infusion to help the immune system recognize and eliminate cancer cells.

TIL Cell Therapy Overview

TIL cell therapy is the autologous transfer of tumor-infiltrating lymphocytes obtained from a patient’s tumor. Learn more about the mechanism of action of TIL cell therapy and the components of this novel cell therapy.

IL-2 Treatment

A short course of high-dose IL-2 is administered after TIL infusion to support T-cell activity. Learn more about best practices in IL-2 treatment as part of TIL cell therapy.
