This study is a prospective, multinational, observational investigation designed to elucidate the real-world effectiveness and treatment patterns of dupilumab therapy in adult patients diagnosed with prurigo nodularis (PN).
The primary objective of this study is to comprehensively characterize the real-world usage of dupilumab for the management of PN.
In addition to this, the study aims to achieve several secondary objectives, including a detailed assessment of the medical history, socio-demographic and disease characteristics of dupilumab-treated PN patients, as well as the evaluation of the long-term real-world effectiveness of dupilumab therapy for PN.
The follow-up period will be 18 months or until death, loss to follow-up, or withdrawal, whichever comes first.

| Mean change in EQ-5D-5L | The EQ-5D-5L comprises of five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The patient is asked to indicate their health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. | From baseline up to month 18 |
| Mean change in Hospital Anxiety and Depression Scale (HADS) total score | The HADS is a Patient-Reported Outcomes (PRO) instrument for screening anxiety and depression in non-psychiatric populations. The HADS consists of 14 items, 7 each for anxiety and depression symptoms. Patients select a response from 0 to 3 for each item, based on how they have been feeling in the past week. Scores range from 0 to 21 for each subscale. HADS anxiety (HADS-A) and HADS depression (HADS-D) scores ≤ 7 indicate no clinically relevant symptoms (normal), 8 to 10 borderline abnormal (borderline case), and 11 to 21 abnormal (maximum 21) indicating more severe symptoms. | From baseline up to month 18 |
