Avelumab plus axitinib vs sunitinib for advanced renal cell carcinoma: Japanese subgroup analysis from JAVELIN Renal 101.

The phase 3 JAVELIN Renal 101 trial of avelumab + axitinib vs sunitinib in patients with treatment-naive advanced renal cell carcinoma (RCC) demonstrated significantly improved progression-free survival (PFS) and higher objective response rate (ORR) with the combination vs sunitinib. Japanese patients enrolled in the study (N=67) were randomized to receive avelumab + axitinib (N=33) or sunitinib (N=34); 67% vs 59% had PD-L1+ tumors (≥1% of immune cells) and 6%/64%/27% vs 6%/82%/12% had IMDC favorable/intermediate/poor risk status. In patients who received avelumab + axitinib vs sunitinib, median PFS (95% CI) was not estimable (8.1 months, not estimable) vs 11.2 months (1.6 months, not estimable) (HR, 0.49; 95% CI, 0.152, 1.563) in patients with PD-L1+ tumors and 16.6 months (8.1 months, not estimable) vs 11.2 months (4.2 months, not estimable) (HR, 0.66; 95% CI, 0.296, 1.464) in patients irrespective of PD-L1 expression. Median OS has not been reached in either arm in patients with PD-L1+ tumors and irrespective of PD-L1 expression. ORR (95% CI) was 60.6% (42.1%, 77.1%) vs 17.6% (6.8%, 34.5%) in patients irrespective of PD-L1 expression. Common treatment-emergent adverse events (all grade; grade ≥3) in each arm were hand-foot syndrome (64%; 9% vs 71%; 9%), hypertension (55%; 30% vs 44%; 18%), hypothyroidism (55%; 0% vs 24%; 0%), dysgeusia (21%; 0% vs 56%; 0%), and platelet count decreased (3%; 0% vs 65%; 32%). Avelumab + axitinib was efficacious and tolerable in treatment-naive Japanese patients with advanced RCC, which is consistent with results in the overall population. Clinicaltrials.gov identifier: NCT02684006.
