Abstract

Background: Upadacitinib is an oral, selective Janus kinase inhibitor. Aim: To assess the efficacy and safety of upadacitinib in patients with moderate-to-severe ulcerative colitis following 16-week extended induction therapy, and 52-week maintenance therapy in patients achieving clinical response after 16-week extended induction therapy. Methods: Patients without clinical response to 8 weeks' upadacitinib 45 mg once daily induction therapy in two induction trials were eligible for an additional 8 weeks of therapy. Patients achieving clinical response at Week 16 were subsequently re-randomised (1:1) to upadacitinib 15 or 30 mg once daily for 52-week maintenance therapy. Efficacy was assessed at induction Week 16 (integrated) and maintenance Week 52; safety was assessed throughout. Results: Overall, 127/663 (19.2%) patients did not achieve clinical response to upadacitinib 45 mg at Week 8 and received an additional 8 weeks of therapy; 75/127 (59.1%) subsequently achieved clinical response at Week 16 and entered the maintenance trial. At Week 52, 26.5% of patients receiving upadacitinib 15 mg, and 43.6% receiving 30 mg, achieved clinical remission; efficacy was observed across all other endpoints with both doses. Herpes zoster rates increased with longer duration (16 weeks) of exposure to upadacitinib 45 mg during induction compared with the same population during the first 8 weeks. No other new safety signals were observed, and results are otherwise consistent with the known safety profile of upadacitinib. Conclusions: Patients without clinical response after 8 weeks' upadacitinib 45 mg induction therapy, may benefit from an additional 8 weeks of therapy. Clinical trial registration: NCT02819635; NCT03653026.
