Earlier this year, Simmons revealed he had been diagnosed with skin cancer — specifically basal cell carcinoma — and received treatment to remove the cancerous cells.

The trial included patients with BCG-unresponsive carcinoma in situ of the bladder, a condition that is notoriously difficult to treat and often leads to radical cystectomy.

One reason clear cell renal cell carcinoma is so difficult to treat is because it is a so-called "cold" tumor -- one in which cancer cells are unrecognizable by immune cells.
