Key Advances Across Kidney Cancer Research and Management at KCRS 2025

At the 2025 Kidney Cancer Research Summit hosted by KidneyCAN, CancerNetwork® spoke with a variety of leading experts about key developments in the research and management of kidney cancer. Throughout the meeting, presenters shared their findings related to updated clinical trial results, personalized cancer vaccines, potential biomarkers of interest, and other advancements in the field.

Thomas Powles, MBBS, MCRP, MD, discussed outcomes from a quality-adjusted survival time without symptoms or toxicity (Q-TWiST) analysis of the phase 3 LITESPARK-005 trial (NCT04195750), in which investigators evaluated treatment with belzutifan (Welireg) vs everolimus (Afinitor) among patients with advanced renal cell carcinoma (RCC).¹ Powles, a professor of genitourinary oncology, lead for solid tumor research, and director of Barts Cancer Institute at St Bartholomew’s Hospital, Queen Mary University of London, stated that these data demonstrate how belzutifan is more active and better tolerated than everolimus in this patient population.

David A. Braun, MD, PhD, assistant professor at Yale School of Medicine and member of the Center of Molecular and Cellular Oncology within the Yale Cancer Center, detailed his presentation on a personalized neoantigen cancer vaccine as a treatment for those with RCC.² Based on his presentation, Braun highlighted how neoantigen vaccines may effectively yield T-cell responses in patients, illustrating a need for additional, larger studies to elucidate the clinical activity of this modality in an adjuvant setting.

Additionally, Wenxin (Vincent) Xu, MD, a medical oncologist at Dana-Farber Cancer Institute and an assistant professor of medicine at Harvard Medical School, spoke about his presentation on how kidney injury molecule-1 (KIM-1) may serve as a prognostic biomarker of response to therapy in patients with RCC.³ His research posed questions on how KIM-1 can inform the use of adjuvant therapy or specific therapeutic combinations like nivolumab (Opdivo) plus ipilimumab (Yervoy) for this patient population.

Eric Jonasch, MD, gave an overview of his presentation focused on the Kidney Cancer Research Consortium, a research partnership spanning 7 institutions dedicated to facilitating mechanistic, hypothesis-testing clinical trials in RCC.⁴ Jonasch, a professor in the Department of Genitourinary Medical Oncology of the Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center, described how this collaboration aims to link identifiable biological characteristics of RCC subtypes to specific treatment strategies while developing predictive biomarkers.
