Pegilodecakin Combined with Anti-PD-1 Monoclonal Antibodies for Patients with Advanced Renal Cell Carcinoma (IVY): A Multicentre, Open-Label, Phase 1b Trial
2019
Background: Interleukin (IL)-10 has anti-inflammatory and CD8+ T-cell-stimulating activities. Pegilodecakin (pegylated IL-10) induces oligoclonal T-cell expansion and has single-agent activity in advanced renal cell cancer (RCC). We assessed the safety and efficacy of pegilodecakin and anti-PD-1 monoclonal antibodies in advanced RCC.
Methods: This study was a multicenter, open-label, phase 1b trial at ten cancer research centres in the US. Patients with advanced metastatic RCC were enrolled and treated with daily subcutaneous pegilodecakin at 10 or 20 µg/kg combined with either 3 mg/kg nivolumab twice weekly or 2 mg/kg pembrolizumab three times weekly. The primary endpoint was safety and tolerability. The secondary endpoint was clinical activity and tumour response, measured by immune-related response criteria (irRC). The study is registered with ClinicalTrials.gov (NCT02009449).
Findings: From February 2015 to November 2016, 38 patients enrolled, and 35 patients were evaluable for response by investigators. Six patients had no prior therapy, and 32 patients had prior therapy (30 patients had prior therapy excluding pegilodecakin and checkpoint inhibitors). Of these 30, 27 patients were evaluable by irRC, and 12 (44%) achieved an objective response as assessed by the investigators. Median duration of response was 64·9 weeks. Median OS was not reached, mPFS was 12·5 months, and 1-year survival was 86·2%. All 38 patients were included in the survival and safety analyses; 26 (68%) patients had grade 3/4 treatment-related adverse events, including anaemia (10), thrombocytopenia (8), and hypertriglyceridemia (6). T-cell receptor clonality assessment in circulating T-cells indicated a treatment-dependent expansion of novel T-cell clones, correlating with survival.
Interpretation: Pegilodecakin is a first-in-class long-acting IL-10 receptor agonist. In this patient population, pegilodecakin with anti-PD-1 monoclonal antibodies had a manageable toxicity profile and promising antitumour activity, warranting further study in phase 2 and 3 clinical trials.
Clinical Trial Registration: The study is registered with ClinicalTrials.gov (NCT02009449).
