Recent clinical studies in renal cell carcinoma (RCC) show immunotherapy-based combination regimens offer personalized treatment options, with confirmed benefits of entrenched regimens. Data from trials like CheckMate 214, CheckMate 9ER, and CLEAR support FDA approvals for combinations including nivolumab plus ipilimumab, nivolumab plus cabozantinib, and pembrolizumab plus lenvatinib. Long-term follow-up data reveal significant improvements in overall survival and progression-free survival, with biomarker analyses indicating consistent benefits across various RCC subgroups. The evolving landscape also includes second-line treatments like atezolizumab plus cabozantinib and adjuvant pembrolizumab, as well as HIF2α inhibitors like belzutifan. Research in non–clear cell RCC highlights the potential of immunotherapy combinations, with ongoing studies like PAPMET2 and KEYNOTE-B61 exploring new treatment strategies.
