A Study to Evaluate Efficacy and Safety of Upadacitinib in Adults With Axial Spondyloarthritis

Korábbi kezelés

• Must not have been exposed to any Janus kinase (JAK) inhibitor (including but not limited to upadacitinib [Rinvoq®], tofacitinib [Xeljanz®], baricitinib [Olumiant®], filgotinib, ruxolitinib [Jakafi®], abrocitinib [PF-04965842], and peficitinib [Smyraf®]).
• Prior bDMARD therapy must be washed out.

Más betegség

• Participant must not have a history of an allergic reaction or significant sensitivity to constituents of the study drug.

• Study 1:
  • Must have a clinical diagnosis of ankylosing spondylitis (AS) and meet the modified New York Criteria for AS,
  • Must not have total spinal ankylosis
  • Must have been previously exposed to 1 or 2 bDMARDs (at least 1 tumor necrosis factor [TNF] inhibitor or 1 interleukin [IL]-17 inhibitor [IL-17i]), and must have discontinued the bDMARD therapy due to either lack of efficacy (after at least 12 weeks of treatment with a bDMARD at an adequate dose) or intolerance (irrespective of treatment duration). Prior exposure to two bDMARDs was allowed for no more than 30% of patients; among patients with prior exposure to two bDMARDs, a lack of efficacy to one bDMARD and intolerance to another was permitted, but a patient could not have a lack of efficacy to two bDMARDs
• Study 2:
  • Must have a clinical diagnosis of nr-axSpA fulfilling the 2009 Assessment of SpondyloArthritis international Society (ASAS) classification criteria for axSpA but not meeting the radiologic criterion of the modified New York criteria for AS
  • Must have objective signs of active inflammation consistent with axSpA on magnetic resonance imaging (MRI) of sacroiliac (SI) joints or based on high sensitivity C-reactive protein (hsCRP) > the upper limit of normal (ULN).
  • Prior treatment with at most one bDMARD (either TNF inhibitor or IL-17i) is allowed for at least 20% but no more than 35% of enrolled patients who had to discontinue the prior bDMARD due to either lack of efficacy (after ≥ 12 weeks at an adequate dose) or intolerance (regardless of treatment duration).
• Must have a Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score ≥ 4 at the Screening and Baseline Visits.
• Must have a Total Back Pain score ≥ 4 based on a 0 - 10 numerical rating scale at the Screening and Baseline Visits.
• Has had an inadequate response to at least 2 nonsteroidal anti-inflammatory drugs (NSAIDs) over an at least 4-week period in total at maximum recommended or tolerated doses, or has an intolerance to or contraindication for NSAIDs as defined by the Investigator.
