Background

Avelumab is a human IgG1 monoclonal antibody against PD-L1, and axitinib is a potent inhibitor of VEGFR 1, 2, and 3. In a phase 3 study in patients (pts) with treatment-naive advanced renal cell carcinoma (aRCC; NCT02684006), avelumab in combination with axitinib (A+Ax) significantly improved progression-free survival (PFS) irrespective of PD-L1 expression vs sunitinib (S) at the preplanned interim analysis; median PFS was 13.8 mo with A+Ax vs 8.4 mo with S (HR, 0.69; p = 0.0001). Here, we report efficacy and safety in Japanese pts who were enrolled in this study.

Methods

Eligible pts with clear-cell aRCC, ECOG PS ≤ 1, and no prior systemic therapy were randomized 1:1 (stratified by ECOG PS and geographic region) to receive A 10 mg/kg IV Q2W + Ax 5 mg PO BID or S 50 mg PO QD on schedule 4/2. Primary endpoints were PFS by blinded independent central review (BICR) per RECIST v1.1 and overall survival (OS) in pts with PD-L1+ tumors (≥1% of immune cells). Key secondary endpoints were PFS by BICR and OS irrespective of PD-L1 expression. Other secondary endpoints included objective response rate (ORR), and safety.

Results

Japanese pts (N = 67) were randomized to A+Ax (n = 33) or S (n = 34); 67% vs 59% had PD-L1+ tumors; IMDC favorable/intermediate/poor risk status was 6%/64%/27% vs 6%/82%/12%. Median PFS (95% CI) was not estimable (NE) (8.1-NE) with A+Ax vs 11.2 months (1.6-NE) with S (HR, 0.49; 95%CI, 0.15-1.56) in pts with PD-L1+ tumors and 16.6 mo (8.1-NE) with A+Ax vs 11.2 mo (4.2-NE) with S (HR, 0.66; 95% CI, 0.30-1.46) in pts irrespective of PD-L1 expression. Median OS in either arm has not been reached in pts irrespective of PD-L1 expression. ORR (95% CI) was 60.6% (42.1%-77.1%) with A+Ax vs 17.6% (6.8%-34.5%) with S in pts 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%).

Conclusions

A+Ax was efficacious and tolerable in Japanese pts with treatment-naive aRCC, which is consistent with results in the overall population.
