Lynk Pharmaceuticals completes patient enrollment in Phase III trial of Zemprocitinib for ankylosing spondylitis, advancing a potential new autoimmune therapy
Executive summary: Lynk Pharmaceuticals completed patient enrollment in its Phase III clinical trial evaluating Zemprocitinib for ankylosing spondylitis. Reaching full enrollment is a critical precondition for obtaining topline efficacy and safety results, which could support a future NDA/BLA filing and influence Lynk’s valuation in the autoimmune disease space.
Who is involved: Lynk Pharmaceuticals (sponsor), clinical trial sites in China, the United States and other regions, and patients with ankylosing spondylitis.
Likely next: The company will now proceed to data lock, analysis, and announcement of topline results, expected within the next 6‑9 months, followed by potential regulatory interactions if the trial meets its endpoints.
The company announced that enrollment for its pivotal Phase III study of Zemprocitinib, an oral selective TYK2 inhibitor, has been finished. This milestone moves the asset closer to topline data readout and a possible regulatory submission. While the announcement is positive for Lynk’s pipeline, the ultimate commercial success will depend on the trial’s efficacy and safety outcomes versus established biologics in the ankylosing spondylitis market.
