  2. • Ulcerative colitis (UC) is a chronic and progressive inflammatory

    bowel disease, where patients experience recurring symptoms of diarrhea, abdominal pain, and bowel urgency. • The Janus Kinase (JAK) family is composed of intracellular signalling proteins that regulate inflammatory signal transduction pathways and are involved in the pathogenesis of UC.3 - Upadacitinib (UPA) is an oral selective and reversible JAK inhibitor currently under investigation for the management of UC. • UPA demonstrated significantly greater efficacy as an induction therapy compared with placebo (PBO) in patients with moderately to severely active UC during two phase 3 induction trials (U-ACHIEVE Induction [NCT02819635] and U-ACCOMPLISH [NCT03653026]).4,5 The Need for a Targeted Ulcerative Colitis Maintenance Therapy 1.Kaur A, Goggolidou P.

  12. Both UPA15 and UPA30 were well-tolerated in patients with moderately

    to severely active UC. No new types of important safety risks were observed compared to the known safety profile of UPA. Higher rates of certain AESI were reported in UPA treatment arms. UPA30 demonstrated numerically greater clinical efficacy of approximately 10% compared to UPA15 for most endpoints. UPA15 and UPA30 had Significantly Greater Efficacy Compared to PBO for All Primary and Secondary Endpoints at Week 52 Based on Clinical, Endoscopic, and Histologic Evaluations
