Intravesical Adoptive Cell Therapy (ACT) with Tumor Infiltrating Lymphocytes (TIL) for the Treatment of High Grade Non-Muscle Invasive Bladder Cancer that Is Exposed to Bacillus Calmette-Guerin (BCG)
This phase I clinical trial tests the safety and side effects of adoptive cell therapy (ACT) with tumor infiltrating lymphocytes (TIL) given within the bladder (intravesical) and how well this works in treating patients with high grade non-muscle invasive bladder cancer (NMIBC) that has been exposed to bacillus calmette-guerin (BCG). Standard treatment for NMIBC includes BCG given intravesically. BCG has limited response rates and response rates decrease with repeated doses. ACT/TIL is a type of immunotherapy using T-cells that may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. The immune T-cells, called TIL, are taken from a sample of a patients tumor tissue. Parts of the cells are grown in the lab and then given back to the patient directly into the bladder through a catheter. Giving tumor-infiltrating lymphocytes intravesically may kill more tumor cells in patients with high-grade BCG-exposed NMIBC.
