Prospective, Non-interventional Observational Study to Characterize Dupilumab Long-term Treatment, Safety and Patient Reported Outcomes in Chronic Nodular Prurigo (Prurigo Nodularis) in Clinical Routine

OBS17933

Prurigo nodularis (PN) is a skin disease characterized by the presence of single to multiple symmetrically distributed, intensively itching nodules. The main symptom is uncontrollable itching leading to prolonged, repetitive, and uncontrollable rubbing, scratching which in turn causes injuries to the skin. In recent years, number of studies evaluating PN, the affected population and the disease burden has increased but PN remains still understudied. This non-interventional study is intended to describe the long-term effectiveness of dupilumab (Dupixent®) in participants aged 18 years or older and suffering from moderate-to-severe PN who receive dupilumab for PN treatment in a real-world setting in Germany according to the prescribing information (Summary of Product Characteristics \[SmPC\]). The decision to initiate dupilumab treatment is made by the treating physician and participant according to the participant's medical need and to the standard of best medical practice. This decision is made independently and before data inclusion in this non-interventional study.
