The CABONEXT study is the first multicenter retrospective analysis evaluating subsequent systemic therapies after cabozantinib-based treatment in metastatic renal cell carcinoma (mRCC). This interim analysis includes 77 patients receiving subsequent treatments across two cohorts: after cabozantinib–nivolumab first-line treatment (Group A) and after ICI-based first-line treatment followed by cabozantinib (Group B). Time to subsequent treatment failure (TTF) and disease control rate (DCR) remain higher in Group A with a median TTF of 5 months (vs. 3.4 months in Group B) and a DCR of 86% (vs. 48%). Second-generation TKIs, mostly axitinib or lenvatinib, seemed to be the best option in Group B compared to other treatments including everolimus or first-generation TKIs (HR = 3.82, 95%CI [1.64; 8.93],
p = 0.1). These findings already emphasize the need for innovative therapies targeting resistance mechanisms and optimal treatment sequences. Along with ongoing accrual, further analyses are expected.
