Real-World study tests upadacitinib for back pain in axial spondyloarthritis
NCT ID NCT05094128
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how well upadacitinib (RINVOQ) works for people with axial spondyloarthritis, a type of inflammatory arthritis that causes chronic back pain. About 338 adults in Germany will take the drug as prescribed by their doctor and be followed for 52 weeks. Researchers will measure disease activity and pain control using standard questionnaires and blood tests.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- upadacitinib (RINVOQ)
- What this could lead to
- If successful, this study could show that upadacitinib effectively controls disease activity and reduces pain in people with axial spondyloarthritis in everyday clinical settings.
- What could go wrong
- This is an observational real-world study, not a controlled trial, so results may be less definitive. Upadacitinib is already approved, so this is about confirming effectiveness rather than a breakthrough.
