Impact Of Upadacitinib On The Frequency Of Acute Recurrent Anterior Uveitis In Patients With Axial Spondyloarthritis

The UP-FOR-U study is a Phase IV, open-label, interventional study designed to assess the effect of upadacitinib 15 mg once daily on the frequency of acute anterior uveitis (AAU) in adult patients with axial spondyloarthritis (axSpA) and a history of ophthalmologist-confirmed AAU in the 52 weeks prior to baseline. The study will enroll approximately 200 participants across 20 sites in Canada, the United States, and the European Union, comprising both biologic DMARD-inadequate responders (bDMARD-IR) and bDMARD-naïve patients. All participants will receive open-label treatment with upadacitinib for 52 weeks, with monthly remote visits and quarterly in-person visits.

The primary objective is to evaluate the change in the exposure-adjusted incidence rate of ophthalmologist-confirmed AAU events per 100 patient-years during treatment, compared to the 52-week pre-study period. Secondary outcomes include measures of disease activity (e.g., ASDAS), physical function (e.g., BASFI), quality of life (e.g., ASAS-HI, SF-12), pain, sleep (e.g., PSQI), and safety (including adverse events, adverse events of special interest, and serious adverse events).

This study reflects real-world clinical practice and incorporates remote data collection and patient-reported outcomes to improve feasibility and patient engagement. It is designed in accordance with ICH-GCP, FDA, Health Canada, and EMA regulatory requirements.
