- History of an inadequate response to at least two different NSAIDs over a period of 4 weeks in total at the maximum recommended or tolerated doses, or intolerance/contraindication (e.g., allergic reaction, gastrointestinal symptoms or signs, severe arterial hypertension, etc.) for NSAIDs.
- Subjects must have been treated for ≥3 consecutive months prior to the study entry with bDMARD therapy and/or for ≥4 weeks of NSAID therapy, in accordance with local product label for AS or nr-axSpA, but continue to exhibit active SpA, or had to discontinue previous bDMARD and/or NSAID treatment due to intolerability or toxicity, irrespective of treatment duration. A total of 50 subjects who are bDMARD-naïve and 150 subjects who are b-DMARD-IR will be included in the study.
- For all females of child-bearing potential: must not have a positive serum pregnancy test at the Screening Visit and must have a negative urine pregnancy test at Baseline prior to the first dose of study drug (local practices may require serum pregnancy testing at Baseline). Subjects with a borderline serum pregnancy test at Screening must have absence of clinical suspicion of pregnancy or other pathological causes of borderline results and a serum pregnancy test ≥3 days later to document continued lack of a positive result (unless prohibited by local requirements).
- Subjects who are regularly taking NSAIDs or analgesics (including low potency opioids) as part of their axSpA therapy are required to be on a stable dose/dose regimen for at least 7 days prior to the baseline visit. If entering the study on concomitant tramadol, combination of acetaminophen/paracetamol and codeine or combination of acetaminophen/paracetamol and hydrocodone, and/or non-opioid analgesics, subject must be on stable dose(s) for at least 7 days prior to the baseline Visit. However, subject must not have used opioid analgesics (except for combination of acetaminophen/paracetamol and codeine or combination of acetaminophen/paracetamol and hydrocodone which are allowed) within 7 days prior to the BL Visit.

Washout periods are as follows: 4 weeks for Etanercept, 8 weeks for Infliximab, Golimumab, and Certolizumab, 10 weeks for Adalimumab, and Ixekizumab, 12 weeks for Secukinumab. However, subjects should not stop their previous successful biological therapy only to be included in this study.

About this study
Official title: Impact Of Upadacitinib On The Frequency Of Acute Recurrent Anterior Uveitis In Patients With Axial Spondyloarthritis (UP-FOR-U)
This is a Phase IV, open-label, multicenter study evaluating the impact of upadacitinib on the frequency of acute anterior uveitis (AAU) in adults with axial spondyloarthritis (axSpA) and a documented history of AAU in the prior 52 weeks. Approximately 200 participants will be enrolled across North America and Europe, including both biologic DMARD-inadequate responders (bDMARD-IR) and bDMARD-naïve patients. The primary objective is to assess the change in exposure-adjusted AAU event rate during 52 weeks of treatment with upadacitinib 15 mg once daily. Secondary objectives include evaluating the effect of upadacitinib on disease activity, pain, physical function, quality of life, and sleep. Safety and tolerability will also be assessed throughout the study.
Read the detailed description
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Frequency of recurrent acute anterior uveitis (AAU)
To evaluate the impact of upadacitinib on the frequency of recurrent acute anterior uveitis (AAU) over 52 weeks in subjects with active axSpA and a prior AAU event in the 52 weeks prior to baseline, who are switching from bDMARD (North America and Europe), or who are NSAID-IR and bDMARD naïve (Europe), in real world practice.
Measured: 52 Weeks
Secondary outcomes (2)
Proportion of participants achieving low disease activity (ASDAS LDA) at Week 24
The percentage of participants achieving a score of less than 2.1 on the Ankylosing Spondylitis Disease Activity Score (ASDAS) at Week 24. ASDAS is a validated composite index that incorporates patient-reported outcomes and objective measures of inflammation to assess disease activity in axial spondyloarthritis.
Measured: Week 24
Proportion of participants achieving ASAS Health Index (ASAS-HI) ≤5 at Week 52
The percentage of participants who achieve a score of 5 or less on the ASAS Health Index (ASAS-HI) at Week 52. The ASAS-HI is a validated patient-reported outcome measure that evaluates the impact of axial spondyloarthritis on physical function, pain, emotional well-being, and social participation. A score ≤5 indicates better health status and is considered a meaningful clinical threshold.
Measured: Week 52
