New study: can a common painkiller tame back pain in spondyloarthritis?
NCT ID NCT07582146
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a drug called acemetacin can reduce pain and control disease activity in adults with active axial spondyloarthritis, a type of inflammatory arthritis that mainly affects the spine. About 150 people aged 18 to 65 will take a daily pill for 4 weeks. Researchers will measure pain levels, disease activity, and any side effects.
