Efficacy of avelumab plus axitinib versus sunitinib by numbers of IMDC risk factors and target tumor sites at baseline in advanced renal cell carcinoma: long-term follow-up results from JAVELIN Renal 101.

BACKGROUND

In the phase III JAVELIN Renal 101 trial, first-line avelumab + axitinib improved progression-free survival (PFS) and objective response rate versus sunitinib in patients with advanced renal cell carcinoma across all International Metastatic RCC Database Consortium (IMDC) risk groups (favorable, intermediate, and poor); analyses of overall survival (OS) remain immature. Here, we report post hoc analyses of efficacy from the third interim analysis (data cut-off, April 2020) by the numbers of IMDC risk factors and target tumor sites at baseline.

METHODS

Efficacy endpoints assessed were PFS, objective response, and best overall response per investigator assessment (RECIST v1.1) and OS. Best percentage change and percentage change from baseline in target tumor size over time during the study were also assessed.

RESULTS

In patients with 0, 1, 2, 3, or 4-6 IMDC risk factors, hazard ratios [HRs; 95% confidence interval (CIs)] for OS with avelumab + axitinib versus sunitinib were 0.660 (0.356-1.223), 0.745 (0.524-1.059), 0.973 (0.668-1.417), 0.718 (0.414-1.248), and 0.443 (0.237-0.829), and HRs (95% CIs) for PFS were 0.706 (0.490-1.016), 0.709 (0.540-0.933), 0.711 (0.527-0.960), 0.501 (0.293-0.854), and 0.395 (0.214-0.727), respectively. In patients with 1, 2, 3, or ≥4 target tumor sites, HRs (95% CIs) for OS with avelumab + axitinib versus sunitinib were 0.912 (0.640-1.299), 0.715 (0.507-1.006), 0.679 (0.442-1.044), and 0.747 (0.346-1.615), and HRs (95% CIs) for PFS were 0.706 (0.548-0.911), 0.552 (0.422-0.723), 0.856 (0.589-1.244), and 0.662 (0.329-1.332), respectively. Across all subgroups, analyses of objective response rate and complete response rate favored avelumab + axitinib versus sunitinib, and a greater proportion of patients treated with avelumab + axitinib had tumor shrinkage.

CONCLUSIONS

In post hoc analyses, first-line treatment with avelumab + axitinib was generally associated with efficacy benefits versus treatment with sunitinib in patients with advanced renal cell carcinoma across subgroups defined by different numbers of IMDC risk factors or target tumor sites.
