Abstract
Interleukin (IL)-10 has anti-inflammatory and CD8+ T-cell-stimulating properties. Pegilodecakin (pegylated recombinant human IL-10) induces intratumoral antigen-specific CD8 + T-cells and upregulates IFNγ and major histocompatibility complexes (MHC) I and II. Pegilodecakin has single-agent activity with manageable toxicity in advanced renal cell carcinama (aRCC) (data cutoff 24 March 2016). Pegilodecakin with pembrolizumab or nivolumab revealed clinical activity in aRCC (data cutoff 1 July 2018). Here, we report for the first time the results of pegilodecakin+ pazopanib, and final results for monotherapy and long-term follow-up with pegilodecakin + anti-programmed cell death 1 (anti-PD-1) inhibitors (data cutoff 19 February 2019). Phase 1/1b multi-cohort dose escalation IVY study enrolled 353 patients. Sixty-six patients with aRCC were treated with pegilodecakin alone or with pazopanib or anti-PD-1 inhibitor in cohorts A, G, H and I (data cutoff 19 February 2019). Primary endpoints included safety and tolerability. Secondary endpoint was tumor response by immune-related response criteria (irRC). Pegilodecakin plus nivolumab or pembrolizumab yielded median progression-free survival (mPFS) of 13.9 months and 6-month PFS probability of 60%, 76% 1-year overall survival (OS) probability and 61% 2-year OS probability. Pegilodecakin monotherapy produced mPFS of 1.8 months, 6-month PFS probability 25%, 1-year OS 50%, and 2-year OS 17%. Median OS was not reached in both combinations. Objective response rates (ORRs) were 33% with pazopanib and 43% with anti-PD-1. Most common Grade 3/4 treatment-related adverse events included anemia, thrombocytopenia and hypertriglyceridemia. In these heavily pretreated renal cell carcinama cohorts of IVY, pegilodecakin+anti-PD-1 inhibitor showed promising clinical activity. Safety profile of pegilodecakin alone and with anti-PD-1 inhibitors was consistent as previously reported.

Abstract
The incidence of kidney cancer has been increasing steadily and, until recently, there was a substantial lack of effective therapies for a cancer that is now among the 10 most common cancers in men and women. During the past 10 years, novel therapies have been developed including antiangiogenic drugs targeting vascular endothelial growth factor and its receptors, immune checkpoint inhibitors, and mammalian target of rapamycin inhibitors that have resulted in a significant improvement in clinical outcomes in a traditionally difficult-to-treat cancer. These new drugs, however, also have important side effects and toxicities that often have an impact on the treatment of these patients. The use of anti-angiogenic drugs often results in the development of hypertension and, less frequently, varying degrees of proteinuria including nephrotic range proteinuria. A variety of agents are used for the treatment of hypertension and proteinuria including blockers of the renin angiotensin system and calcium channel blockers, but there are no randomized clinical trials comparing different therapeutic agents in these patients. Immune checkpoint inhibitors have become one of the cornerstones of therapy in kidney cancer, but their use is linked to a variety of side effects that affect almost every organ and resemble autoimmune diseases. In the kidney, these drugs can induce acute interstitial nephritis in close to 5% of patients with varying degrees of severity that in some cases require discontinuation of treatment and systemic treatment with corticosteroids. Although mammalian target of rapamycin inhibitors now also are part of the therapeutic armamentarium available for these patients, all clinical trials have been performed in patients with normal renal function and therefore their effects in patients with abnormal renal function are not known.
