All patients enrolled in the study between March 2019 and September 2021 were free from kidney cancer at the three-year follow-up in July 2023, marking a major milestone.

The type of kidney cancer they had — stages three and four clear cell renal cell carcinoma (ccRCC) — kills between 85 and 90 percent of patents.
