An Observational Study of Upadacitinib to Assess Change in Disease Activity in Canadian Adult Participants With Moderate-to-Severe Atopic Dermatitis Who Are Inadequate Responders To or Discontinuing Dupilumab

Brief summary

Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. Therapies spread over the skin may not be enough to control the AD in trial participants who require systemic anti-inflammatory treatment. This study will assess the real-world effectiveness of upadacitinib on adult participants with moderate-to-severe AD who are inadequate responders to dupilumab or who are discontinuing from dupilumab due to safety/tolerability reasons. This study also aims to understand upadacitinib utilization patterns in real-world clinical practice. In Canada, upadacitinib is indicated for the treatment of adults and adolescents 12 years of age and older with refractory moderate to severe atopic dermatitis (AD) who are not adequately controlled with a systemic treatment (e.g., steroid or biologic) or when use of those therapies is inadvisable. CAN UpTIMISE will enroll approximately 100 adult participants, 18 years of age and above, with moderate-to-severe AD who are inadequate responders to dupilumab or are discontinuing from dupilumab from up to 25 sites in Canada. Participants will receive oral upadacitinib tablets as prescribed by the physician prior to enrolling in this study in accordance with the terms of the local marketing authorization and professional and reimbursement guidelines with regards to dose, population, and indication. The overall duration of the study is approximately 4 Months. Participants will attend regular visits per routine clinical practice. The effect of the treatment will be checked by medical assessments, using questionnaires, and reporting potential side-effects.
