Findings show no difference in overall survival between various treatments for metastatic RCC previously managed with immunotherapy and TKIs.
Neil J. Shah, MBBS, spoke with CancerNetwork® at the 2024 Kidney Cancer Research Summit (KCRS) about findings from a real-world study assessing treatment patterns and outcomes among patients with metastatic renal cell carcinoma (RCC) following prior therapy with immunotherapy and tyrosine kinase inhibitors (TKIs).
Data from the study highlighted patients with metastatic RCC mostly received TKIs with or without immunotherapy following frontline therapy. After immunotherapy-based treatment in the first-line setting, the most common second-line therapy option was cabozantinib (Cabometyx) in 57.4% of patients.
According to Shah, a genitourinary medical oncologist from Memorial Sloan Kettering Cancer Center, findings demonstrated that clinical outcomes such as overall survival were comparable when using different types of treatment regimens in patients who previously received immunotherapy or TKI-based therapy. Overall, the findings suggest the need to develop more novel treatment strategies to improve outcomes in this setting.
Transcript:
The kidney cancer treatment landscape is changing rapidly. We have many new treatment regimens in the kidney cancer space, especially within the first-line setting. Now, the question is, what happens after a patient [receives] more than a first-line agent, including immunotherapy [IO] plus IO and IO plus tyrosine kinase inhibitor [TKI] agents? What are the next-line agents they are receiving? What are their efficacy data? That was the rationale for us to study in this poster.
We noted a diverse pattern of different agents used in this setting, with cabozantinib being one of the most common drugs. There are a lot of different combination drugs being used, including IO/TKI combinations. What we noted was that, to our surprise, there was no one agent that was superior. There was no difference in overall survival among all these diverse agents used in this line setting, which was an interesting finding. [Based on these data], we need novel agents in this line or in this space post-IO/TKIs to improve the outcomes.

Belzutifan Improves PFS Across Subgroups for Advanced ccRCC
July 12th 2024“In LITESPARK-005, PFS and response rates favored belzutifan vs everolimus across [several patient subgroups, including] IMDC risk, number of prior lines [of therapy], and number of prior VEGF TKIs, specifically,” said Laurence Albiges, MD, PhD.
