Alan Tan, MD, assistant professor of medicine in the division of hematology and oncology at Vanderbilt University Medical Center, discusses potential biomarkers that are being investigated to optimize treatment of patients with renal cell carcinoma (RCC).

In addition to the development of new targeted therapies, studying biomarkers is another approach to improve outcomes in patients with RCC. Tan says the KIM-1 (kidney injury molecule-1) protein found in plasma is the newest innovation in blood-based biomarkers for RCC. He suggests it could be combined with other biomarkers such as circulating tumor DNA (ctCNA) and methylation signatures to predict outcomes such as low vs high risk of disease recurrence after resection of localized RCC.

In addition, translational research has led to prospective studies on the use of biomarkers in the metastatic setting to select IO (immunotherapy) and TKI (tyrosine kinase inhibitor) combinations. The phase 2 multicenter OPTIC RCC study (NCT05361720) is assigning patients to receive ipilimumab (Yervoy) plus nivolumab (Opdivo) or nivolumab plus cabozantinib (Cabometyx) based on biologic clusters defined by RNA sequences in tumor specimens. Tan says that this study could show prospectively which patients should receive IO/IO or IO/TKI.

0:10 | There's a lot of excitement to come with more translational research. I think biomarkers are incredibly exciting. Whether it's—KIM-1 is the newest innovation that we have, and I think we look forward to how we can apply that KIM-1 biomarker, maybe in combination with other biomarkers like ctDNA or methylation signatures. We do have some translational prospective studies that we're looking at like OPTIC RCC. How does the angiogenic or T-cell enriched clusters actually help us predict who should be allocated to IO/IO vs IO/TKI?
