Use of Nemolizumab in the Treatment of Prurigo Nodularis and Atopic Dermatitis.

Prurigo nodularis and atopic dermatitis are chronic, inflammatory skin conditions characterized by significant pruritus that disrupts daily life. They also involve dysfunction of the T-helper 2 immune response, leading to the over secretion of interleukin-31 (IL-13) in the dermis and serum. Nemolizumab is a new IL-31 receptor antagonist that has shown high efficacy in the treatment of prurigo nodularis (PN) and atopic dermatitis (AD) in multiple phase 3 trials, with a good safety profile. A brief overview of PN and AD including highlights of the findings from three trials of nemolizumab in treating these disorders will be presented herein.
