Dose Escalation Patterns and Associated Costs of Advanced Therapies for Ulcerative Colitis in France and the United Kingdom: A Retrospective Database Analysis.

Background: Dose escalation to optimize advanced therapies is common in ulcerative colitis (UC) to avoid intra-class or inter-class drug switching and maintain clinical response and has impact on costs. Given the limited real-world data available, this study aims to understand real-world dose escalation UC advanced therapies patterns in France and United Kingdom [UK].

Methods: Retrospective study in adult patients with moderate-to-severe UC starting an advanced UC therapy (adalimumab [ADA], golimumab [GOL], infliximab [IFX], tofacitinib [TOF], ustekinumab [UST], or vedolizumab [VED]) with first prescription (and/or dispensation for France) between January 2017 and February 2022 (ie advanced UC therapy new users, by excluding patients who used any of these drugs in the previous 12 months to their index date).
