Clinical Trial Summary

Prurigo nodularis (PN) is a skin condition characterized by symmetrically distributed widespread, pruritic nodules that occurs in patients with chronic pruritus. There are 2 subtypes of PN depending on the association with an atopic dermatitis (AD) : atopic PN (Besnier) and non-atopic PN (Hyde). There are no approved therapies, and treatment options currently used have limited efficacy and their long-term use carries the risk of potential severe toxic effects. The mechanisms triggering PN are still unknown. However, recent findings suggest a major role for the Th2 inflammatory pathway. Beyond advancing the basic understanding of PN pathophysiology, our study might also pave the way for developing novel Th2-targeted therapeutic strategies for PN and AD. The primary objective of this study is to characterize the transcriptional profile of the T lymphocytes isolated from skin samples from patients with PN. This study will allow a gain a deeper understanding of the pathophysiologic mechanism of PN, a better classification of its subtypes, as well as their physiopathologic link with AD. Moreover, it will help shape new effective and safe therapeutic approaches in these diseases which are important for optimal therapeutic management.
