Filter by:This is a Phase 3, multicenter, open-label, pharmacokinetics (PK)/safety study. The study consists of 3 periods: - Screening period: 2 to 4 weeks. - Treatment period: 24 weeks. - Post-intervention follow-up period: 16 weeks. The study duration will be approximately 42 to 44 weeks for each participant (including screening, treatment, and follow-up periods). The total number of planned study visits for each participant will be 6.
The goal is to evaluate the efficacy and safety of tofacitinib in treating refractory prurigo nodularis.The main questions it aims to answer are 1. whether tofacitinib is effective in treating prurigo nodularis in the longpterm. 2. whether tofacitinib is safe in prurigo nodularis patients in the longpterm.
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.
Prurigo nodularis (PN) is a common dermatological disorder, manifested as scaly nodules which appear mainly on the extensor surfaces of the limbs. PN may appear secondarily to skin scratching in chronic hepatitis, liver cirrhosis, uremia, hypothyroidism etc. Nevertheless, in many cases no underlying physical disease is present. According to the literature, in fifty percent of the patients there is co-morbidity with depression, anxiety or somatoform disorders. We hypothesize that a group of these patients may benefit from antidepressant therapy.
