Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to evaluate the efficacy and safety of LNK01001 in subjects with active ankylosing spondylitis.

The study is comprised of a 16-week randomized, double-blind, parallel-group, placebo-controlled period (the Double-Blind Period); a 36-week open-label, long-term extension period (the Open-Label Extension Period). In the Double-Blind Period, participants will be randomized in a 1:1 ratio to receive either LNK01001 or placebo twice daily (BID). Participants in the placebo group will be switched to LNK01001 BID at Week 16 in the Open-Label Extension Period.
