PEGylated IL-10 (Pegilodecakin) Induces Systemic Immune Activation, CD8 T Cell Invigoration and Polyclonal T Cell Expansion in Cancer Patients

Abstract

Tumor-reactive T cell exhaustion prevents the success of immune therapies. Pegilodecakin activates intratumoral CD8 T cells in mice and induces objective tumor responses in patients. Here we report that pegilodecakin induces hallmarks of CD8 T cell immunity in cancer patients, including elevation of interferon-γ and GranzymeB, expansion and activation of intratumoral CD8 T cells, and proliferation and expansion of LAG-3 PD-1 CD8 T cells. On pegilodecakin, newly expanded T cell clones, undetectable at baseline, become 1%-10% of the total T cell repertoire in the blood. Elevation of interleukin-18, expansion of LAG-3 PD-1 T cells and novel T cell clones each correlated with objective tumor responses. Combined pegilodecakin with anti-PD-1 increased the expansion of LAG-3 PD-1 CD8 T cells.
