Efficacy and safety of avelumab plus axitinib in elderly patients with advanced renal cell carcinoma: extended follow-up results from JAVELIN Renal 101.

BACKGROUND

In the phase III JAVELIN Renal 101 trial, first-line avelumab plus axitinib demonstrated a progression-free survival (PFS) and objective response rate (ORR) benefit versus sunitinib in patients with advanced renal cell carcinoma (aRCC). However, efficacy in elderly patients remains unclear. We report efficacy and safety by age group from the second interim analysis of overall survival (OS).

PATIENTS AND METHODS

PFS and ORR as per blinded independent central review (RECIST 1.1), OS, and safety were assessed in patient groups aged <65, ≥65 to <75, and ≥75 years.

RESULTS

In the avelumab plus axitinib and sunitinib arms, 271/138/33 and 275/128/41 patients aged <65, ≥65 to <75, and ≥75 years, respectively, were randomized. At data cut-off (January 2019), median PFS [95% confidence interval (CI)] with avelumab plus axitinib versus sunitinib in these respective age groups was 11.6 (8.4-19.4) versus 6.9 (5.6-8.4) months [hazard ratio (HR), 0.63; 95% CI 0.501-0.786], 13.8 (11.1-18.0) versus 11.0 (7.8-16.6) months (HR, 0.88; 95% CI 0.627-1.231), and 13.8 [7.0-not estimable (NE)] versus 9.8 (4.3-NE) months (HR, 0.76; 95% CI 0.378-1.511). Median OS (95% CI) in the respective age groups was not reached (NR) (NE-NE) versus 28.6 (25.5-NE) months (HR, 0.74; 95% CI 0.541-1.022), 30.0 (30.0-NE) versus NR (NE-NE) months (HR, 0.89; 95% CI 0.546-1.467), and 25.3 (19.9-NE) versus NR (19.4-NE) months (HR, 0.87; 95% CI 0.359-2.106). ORR (95% CI) in the respective age groups was 49.4% (43.3% to 55.6%) versus 27.3% (22.1% to 32.9%), 60.9% (52.2% to 69.1%) versus 28.9% (21.2% to 37.6%), and 42.4% (25.5% to 60.8%) versus 22.0% (10.6% to 37.6%). In the avelumab plus axitinib arm, grade ≥3 adverse events (AEs) and immune-related AEs occurred in 76.9%/81.2%/72.7% and 45.5%/48.1%/36.4% in the respective age groups.

CONCLUSIONS

First-line avelumab plus axitinib demonstrated favorable efficacy across age groups, including patients aged ≥75 years. OS data were still immature; follow-up is ongoing. The safety profile was generally consistent across age groups.
