The latest research supports immune checkpoint inhibitor therapy for clear cell and non–clear cell renal cell carcinoma, but patient selection is key to optimize outcomes, according to a medical oncologist from the Dana-Farber Cancer Institute, Boston.

Michael Serzan, MD, who works in the Lank Center for Genitourinary Oncology at the institute, stated this at the 2024 National Comprehensive Cancer Network Annual Conference, during a presentation.

A systematic review and meta-analysis published in 2022 in European Urology Open Science summarized six randomized controlled trials with a total of 5121 adult patients. In the review, the researchers found that immune checkpoint inhibitors plus vascular endothelial growth factor tyrosine kinase inhibitors (VEGF TKI) were associated with consistent improvements across all risk groups for metastatic renal cell carcinoma.

Additional newer research supports the use of immunotherapy combinations or other immunotherapy plus tyrosine kinase inhibitors as first-line or adjuvant treatments for renal cell carcinoma, Dr. Serzan said during an interview. However, more genomic and histology-directed therapies are needed, he noted.
 

Tips for Evaluating Risk When Treating Renal Cell Carcinoma?

For patients with localized clear cell renal cell carcinoma who have undergone partial or radical nephrectomy, there are several models that estimate the risk of recurrence based on pathologic tumor stage, grade, histology, invasion, and the extent of necrosis, Dr. Serzan said. These models can help guide selection of patients who may be at high risk of recurrence and, therefore, may benefit from adjuvant therapy.

For patients with metastatic clear cell renal cell carcinoma, the IMDC and MSKCC prognostic models stratify patients to favorable, intermediate, and poor risk groups based on clinical and lab factors. The IMDC risk stratification model is used as a prognostic model to stratify patients diagnosed with metastatic kidney cancer, Dr. Serzan said.
 

What Research Supports Treatments for Clear Cell and Non–Clear Cell Renal Cell Carcinoma?

The US Food and Drug Administration (FDA) approved pembrolizumab in 2021 for the adjuvant treatment of renal cell carcinoma (RCC) in patients with intermediate-risk or high-risk of recurrence after nephrectomy or after nephrectomy and resection of metastatic lesions.

Pembrolizumab is the first adjuvant therapy shown to significantly improve overall survival in these patients, Dr. Serzan said. In the KEYNOTE-564 study, published in 2024 in the Journal of Clinical Oncology, pembrolizumab demonstrated an improvement in disease free survival as well as overall survival when compared with placebo.

Several similar studies of adjuvant immune checkpoint inhibitors for renal cell carcinoma involving atezolizumab vs. placebo, nivolumab plus ipilimumab vs. placebo, and nivolumab vs. observation have not shown significant benefits in terms of disease-free survival, Dr. Serzan noted.

The current NCCN Clinical Practice Guidelines in Oncology for Kidney Cancer (Version: 3.2024), which were updated this year, support the use of adjuvant pembrolizumab for patients with stage II, III, or IV clear cell renal cell carcinoma after partial or radical nephrectomy, he said.

Looking ahead, biomarkers are needed to understand the risk of recurrence, and which patients benefit from adjuvant pembrolizumab, Dr. Serzan added.
 

 

 

Where Do VEGF-TKIs Fit In?

VEGF is a treatment target for renal cancer, and angiogenesis inhibition with VEGF TKIs continues to be a subject for study, Dr. Serzan said. In the CABOSUN study, published in the Journal of Clinical Oncology in 2017, patients were randomized to cabozantinib or sunitinib. Progression-free survival was significantly greater in the cabozantinib group, but overall survival was similar between the groups.

In another randomized trial, the CheckMate 214 study, patients received either sunitinib or a combination of nivolumab plus ipilimumab in four doses given every 3 weeks, followed by nivolumab alone every 2 weeks, and these patients were stratified by risk, Dr. Serzan noted.

The median progression-free survival was 12.4 months in the combination group vs. 8.5 months in the sunitinib group for patients at intermediate or poor risk of recurrence. The median progression-free survival was significantly greater in sunitinib patients with favorable risk vs. combination patients with favorable risk (28.9 months vs. 12.4 months).

Overall survival was higher for all patients with combination therapy vs. sunitinib regardless of risk stratification.

Dr. Serzan reviewed the pros of VEGF/PD1 (programmed death-ligand 1) combinations as including a high response rate (generally 52%-72%) and a low rate of primary progressive disease (5%-12%), as well as favorable progression-free and overall survival and low rates of immune-related adverse events.

However, cons of this treatment include lack of data on treatment-free survival as well as the decrease in progression-free survival and overall survival hazard ratios over time and potential chronic VEGF/TKI toxicities, he said.
 

What Treatments Are Recommended for Metastatic Clear Cell Renal Cell Carcinoma Now?

Clear cell renal cell carcinoma (ccRCC) is the most prevalent histological subtype of kidney cancer, accounting for 70%-75% of cases, and these patients are prone to metastasis, recurrence, and resistance to radiotherapy and chemotherapy, according to authors of a recent review published in Frontiers in Oncology.

Dr. Serzan shared his preferred protocol for treatment-naive metastatic ccRCC patients, based on the NCCN guidelines for Kidney Cancer (Version: 3.2024) that had been updated in 2024.

For those with sarcomatoid features, he favors the use of nivolumab/ipilimumab combination, while those without sarcomatoid features, if highly symptomatic, may be treated with any of several combinations: nivolumab/ipilimumab, axitinib/pembrolizumab, cabozantinib/nivolumab, or lenvatinib/pembrolizumab.

For asymptomatic patients without sarcomatoid features, treatment depends on eligibility for immune checkpoint inhibitors or ipilimumab, Dr. Serzan said. His first choice for those eligible is nivolumab/ipilimumab; those not eligible for ipilimumab could receive nivolumab, pembrolizumab, axitinib/pembrolizumab, cabozantinib/nivolumab, or lenvatinib/pembrolizumab.

For patients not eligible for ICIs because of uncontrolled autoimmune disease, or high-dose glucocorticoids, Dr. Serzan recommended treatment with cabozantinib, lenvatinib/everolimus, pazopanib, or sunitinib.
 

What are Some Takeaway Points About Immunotherapy and Renal Cell Carcinoma?

“Immunotherapy has revolutionized treatment for renal cell carcinoma, with significant increases in overall survival, and a small but consistent cure fraction that was unimaginable 10 years ago,” Eric Jonasch, MD, of The University of Texas MD Anderson Cancer Center and vice-chair of the NCCN Guidelines Panel for Kidney Cancer, said in an interview.

 

 

However, challenges to implementing new treatments in clinical practice are ongoing, he said. The major challenges facing clinicians, patients, and their families include the cost of therapy, logistics of treatment administration, and managing toxicities, Dr. Jonasch said.  

Patient selection is key to optimize outcomes with immunotherapy, and shared decision-making is essential to ensure that choice of therapy matches patient expectations and needs — and to maintain clear and open channels of communication while patients are on therapy, Dr. Jonasch said. “In my clinic, we empower patients to take treatment breaks to manage side effects, thereby optimizing quality of life while maintaining treatment efficacy,” he said.

Although significant progress has been made in managing renal cell carcinoma, more research is needed to increase the proportion of patients cured, said Dr. Jonasch. “A clearer understanding of the determinants of response and resistance, which will be driven by information rich clinical trials, will help move us in that direction,” he said.

Dr. Serzan had no financial conflicts to disclose. Dr. Jonasch disclosed research support from AbbVie, Arrowhead, Aveo, BMS, Corvus, Merck, NiKang, ProfoundBio, and Telix, as well as honoraria from Aveo, Eisai, Exelixis, GlaxoSmithKline, Ipsen, Merck, Novartis, NiKang, and Takeda.
