  • Summary

  • At the 2024 Kidney Cancer Research Summit (KCRS), CancerNetwork® spoke with various experts in the kidney cancer field about potential advancements in disease detection and updated efficacy data on immunotherapy and other treatment strategies in patients with renal cell carcinoma (RCC).


    Karl Semaan, MD, MSc, a postdoctoral oncology research fellow at Dana-Farber Cancer Institute, discussed the implications of findings related to the use of an investigational tissue-informed liquid biopsy epigenomic profiling tool for detecting sarcomatoid differentiation in RCC.1 According to Semaan, this method may avoid the sampling errors and spatial heterogeneity challenges associated with traditional biopsy strategies.


    Additionally, Neil J. Shah, MBBS, an assistant attending physician from Memorial Sloan Kettering Cancer Center, spoke about data from a real-world study evaluating treatment patterns and outcomes in those with metastatic RCC following prior receipt of immunotherapy and tyrosine kinase inhibitors (TKIs).2 Data showed no differences in overall survival (OS) outcomes across different immunotherapy- and TKI-containing regimens. Based on these findings, Shah emphasized a need for additional novel therapeutic approaches to help improve outcomes in later-line settings of treatment.


    Bradley A. McGregor, MD, director of Clinical Research for the Lank Center of Genitourinary Oncology and medical oncologist specializing in genitourinary malignancies at Dana-Farber Cancer Institute, highlighted findings from his presentation on a phase 1b study (NCT04627064) evaluating treatment with abemaciclib (Verzenio) in a pretreated metastatic clear cell RCC population.3 Among 11 patients who received abemaciclib, 1 had stable disease, 8 had progressive disease, and 2 were not evaluable for response. Additionally, the median progression-free survival (PFS) and overall survival (OS), respectively, was 1.8 months (95% CI, 1.5-1.9) and 9.1 months (95% CI, 2.1-15.3).


    Although abemaciclib monotherapy yielded no responses in the study, McGregor highlighted the potential clinical utility of administering the agent in combination with other therapies. Findings from his presentation suggested that CDK4/6 inhibitors may demonstrate a synergistic effect when combined with HIF-2α inhibitors, which is a potential strategy that investigators are evaluating with belzutifan (Welireg) and palbociclib (Ibrance) combination therapy as part of the phase 1/2 LITESPARK-024 trial (NCT05468697).
