Prurigo Nodularis Clinical Trial
— GLOBOSPINOfficial title:
A Prospective Observational Study of Patients Receiving Dupilumab for Prurigo Nodularis
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.

Secondary | 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 60 | |
Secondary | 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 60 | |
Secondary | Proportion of patients reported working, absenteeism score, presenteeism score, and overall impairment working score using the Work Productivity and Activity Impairment (WPAI) questionnaire | The Work Productivity and Activity Impairment General Health (WPAI-GH) is a 6-item Patient-Reported Outcomes (PRO) instrument that measures the effect of a condition on productivity during work and regular activities in the seven days prior to completion. The instrument comprises 4 domains: absenteeism, presenteeism, overall work impairment, and activity impairment due to health. WPAI-GH outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes. | From baseline up to month 60 | |
Secondary | Percentage of patients experiencing AEs and SAEs | From baseline up to month 60 |
