A Study to Describe the Real-world Effectiveness, Safety and Patterns of Use of Dupilumab in Patients With Chronic Spontaneous Urticaria

This is a decentralized study designed to describe the real-world effectiveness, safety, and patterns of use of dupilumab in patients with chronic spontaneous urticaria (CSU). This study will be conducted in the United States and will collect data available from participants' medical files, other items routinely collected during disease management in clinical practice, and patient-reported outcomes related to disease, work productivity, quality of life, and CSU-related hospitalizations. Participation in this study is the patient's own choice and is entirely voluntary. The treating physician prescribes dupilumab treatment as part of routine care, independently of the study. Once the decision to prescribe dupilumab is made by the treating physician, patients can self-screen and will be contacted by the Virtual Research Coordination Center to determine potential study eligibility. Patients will be enrolled if they provide an informed consent and meet all inclusion criteria and none of the exclusion criteria. The duration of the study for each participant is 24 months. All patients will be followed for 24 months or until death, loss to follow-up, or withdrawal, whichever occurs first.
