NCT ID NCT07237568
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether the experimental drug LNK01001 can reduce pain and stiffness in adults with active ankylosing spondylitis, a type of arthritis that mainly affects the spine. About 352 participants will receive either LNK01001 or a placebo twice daily for 16 weeks, then everyone can receive the drug for another 36 weeks. The main goal is to see if more people on LNK01001 achieve at least a 40% improvement in symptoms compared to placebo.
