argenx Meets Primary Endpoint in Phase II Celiac Disease Study

argenx announced positive phase II results for FB102, an investigational therapy for celiac disease, meeting its primary endpoint with significant improvements in intestinal tissue measures versus placebo and no new safety signals. The company plans to advance FB102 into late-stage development and evaluate it for other autoimmune conditions. However, the stock declined nearly 12% following a separate announcement that argenx discontinued its phase III UNITY study for Vyvgart Hytrulo in Sjögren's disease.
