Researchers are evaluating the real-world effectiveness of nemolizumab in treating moderate-to-severe Prurigo Nodularis (PN) in adults. This non-interventional, prospective, multicenter study focuses on physician assessments and patient-reported outcomes over approximately 12 months in routine clinical settings. The study aims to measure improvements using both investigator and patient evaluations at Month 6. Treatment with nemolizumab (Nemluvio) is decided by the participant's physician before enrollment, with no additional visits or tests beyond usual care. Visit schedules follow standard medical practice rather than study requirements. A sub-study in Germany and the UK involves daily remote completion of Peak Pruritus Numerical Rating Scale (PP NRS) and Sleep Disturbance NRS from Day -1 to Day 14 without clinic visits. Participants will be involved in routine clinical visits where physician assessments and patient-reported outcomes are collected. The main outcomes measured include the Investigator Global Assessment of chronic Prurigo (IGA-CPG stage) and Peak Pruritus Numerical Rating Scale at 6 months. Data collection relies on standard practice, with no extra procedures, and monitoring occurs throughout the study duration of about one year.
