    Kurzfassung: 4504 Background: Combining an immune checkpoint inhibitor with a targeted antiangiogenic agent may leverage complementary mechanisms of action for treatment of aRCC. Avelumab is a fully human anti–PD-L1 IgG1 antibody with clinical activity in various tumor types; axitinib, a VEGF receptor inhibitor, is approved for second-line treatment of aRCC. JAVELIN Renal 100 (NCT02493751) is a phase Ib study evaluating safety and clinical activity of avelumab + axitinib in treatment-naïve pts with aRCC; updated results are reported here. Methods: Eligible pts had confirmed clear-cell aRCC, ≥1 measurable lesion, fresh or archival tumor specimen, ECOG PS ≤1, and no prior systemic therapy. Pts received avelumab 10 mg/kg IV Q2W + axitinib 5 mg orally BID until progression, unacceptable toxicity, or withdrawal. Endpoints included safety (NCI CTCAE v4.03) and objective response (RECIST v1.1). Results: As of Dec 30, 2016, 55 pts (median age 60.0 yrs [range 42.0–76.0]; 76.4% male; 34.5% ECOG PS = 1) were enrolled. 54 pts were treated with avelumab for a median of 24.1 wks (range 2.0–62.0); 55 pts were treated with axitinib for a median of 25.3 wks (range 3.0-61.0). 51 pts (92.7%) had an avelumab-related adverse event (AE) with the therapy combination, the most common (≥30% any grade) were fatigue and diarrhea (30.9% each). 10 pts (18.2%) had a max grade 3 and 1 pt (1.8%) had a max grade 4 avelumab-related AE. 52 pts (94.5%) had an axitinib-related AE with the therapy combination; the most common (≥30% any grade) were diarrhea (52.7%), hypertension (45.5%), dysphonia (43.6%), and fatigue (43.6%). 24 pts (43.6%) had a max grade 3 and 5 pts (9.1%) had a max grade 4 axitinib-related AE. 2 deaths occurred in the study during the reporting period: 1 due to progression and 1 related to both treatments (myocarditis). An AE led to discontinuation of avelumab in 5 pts (9.1%) and axitinib in 4 pts (7.3%). Confirmed ORR was 54.5% (95% CI 40.6–68.0) based on 2 CR and 28 PR. Unconfirmed ORR was 60.0% (95% CI 45.9–73.0). Conclusions: The safety profile of the combination of avelumab + axitinib appears manageable and consistent with those agents administered as monotherapy, and early encouraging antitumor activity was observed. Follow-up is ongoing. Clinical trial information: NCT02493751.
