Cytokine changes during immune-related adverse events and corticosteroid treatment in melanoma patients receiving immune checkpoint inhibitors

Abstract

Background

Immune checkpoint inhibitors (ICIs) often cause immune-related adverse events (irAEs), most of which are treated with corticosteroids despite evidence suggesting that corticosteroids may blunt antitumor efficacy. We sought to identify cytokine changes that correlate with irAEs and study the impact of corticosteroid treatment on cytokine levels.

Methods

We analyzed expression of 34 cytokines in 52 melanoma patients who developed irAEs during therapy with ICIs. Luminex serum assay was performed at baseline, 1, 2, and 3 months after starting ICI. Baseline cytokine levels and longitudinal log2 fold-change was compared with incidence and grade of irAEs. Cytokine patterns were compared between patients based on development of irAEs and steroid treatment.

Results

There were no differences in baseline cytokine levels between patients who developed grade 1–2 irAEs (N = 28) vs. grade 3–4 irAEs (N = 24). Dermatitis patients (N = 8) had significantly higher baseline Ang-1 (p = 0.006) and CD40L (p = 0.005). Pneumonitis patients (N = 4) had significantly higher baseline IL-17 (p = 0.009). Colitis patients (N = 8) had a trend toward decreased GCSF (p = 0.08). Through Spearman’s correlation analysis, patients who developed irAEs without receiving corticosteroids (N = 23) exhibited harmonization of cytokine fold-change, with 0/276 pairwise comparisons demonstrating significant divergence. In contrast, corticosteroid treatment in patients with irAEs (N = 15) altered fold-change to a discordant pattern (42/276 diverged, 15.2%). This discordant cytokine pattern in patients receiving corticosteroids is similar to the cytokine pattern in patients who did not develop irAEs (N = 8) during the longitudinal profiling period (41/276, 14.9%).

Conclusions

Baseline levels of certain cytokines correlate with specific irAEs in melanoma patients receiving ICIs. irAEs drive a concordant pattern of cytokine fold-change, which is disrupted by corticosteroid treatment.
