Clinical Trial Summary

This is a pilot study of combination low dose rate brachytherapy (LDR) added to standard of care (SOC) immunotherapy in stage III and IV melanoma, stage IV renal call cancer, and stage IV urothelial cancer.

Description:

The purpose of this study is to evaluate the effect of combining LDR with immune checkpoint inhibition in stage III and IV melanoma, stage IV renal call cancer, and stage IV urothelial cancer. This involves the addition of a treatment called brachytherapy to SOC immunotherapy. Brachytherapy is a form of radiation therapy where radioactive pellets are placed within a tumor to temporarily irradiate the tumor at a low level. This is the first time that this combination (immunotherapy and brachytherapy) has been used in humans. The objectives of this study are to evaluate the effect of combining LDR with immunotherapy, determine safety and feasibility, generate a toxicity profile, evaluate response, and overall survival.

CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions, progressive disease (PD) is >20% increase in sum of diameters of target lesions, stable disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.
