Unmet Needs in Real-World Advanced Therapy-Naïve and -Experienced Patients with Moderately to Severely Active Ulcerative Colitis in the United States.

Abstract

Despite availability of advanced therapies (ATs) for ulcerative colitis (UC), many patients fail to respond to treatment. This study examined real-world clinical and humanistic outcomes associated with current treatments in patients with UC. This cross-sectional study used US data from the Adelphi Real World Disease Specific Programme for inflammatory bowel disease from before (2017-2018) and during the COVID-19 pandemic (2020-2021). Physicians (gastroenterologists) seeing > 5 patients/month reported patients' disease characteristics, current symptoms and treatments, and reasons for treatment choices for their next seven consecutive patients aged ≥ 18years with moderately to severely active UC before current treatment. Patients were asked to complete the EQ-5D-5L health-related quality of life (HRQoL) measure. ATs included tumor necrosis factor inhibitors (TNFis), integrin receptor antagonists, interleukin-12/23 antagonists, and Janus kinase inhibitors. Patients were classified as AT-naïve or AT-experienced based on current treatment received for ≥ 8weeks and further classified as responders or non-responders based on symptoms, disease flare status, and remission. Descriptive analyses are presented. The 2017-2018 cohort included 92 physicians and 539 patients (208 [38.6%] AT-experienced). The 2020-2021 cohort included 73 physicians and 448 patients (349 [77.9%] AT-experienced). TNFis were the most common ATs. In 2017-2018, 195 (58.9%) AT-naïve and 113 (54.3%) AT-experienced patients were non-responders; in 2020-2021 this was 57 (57.6%) and 182 (52.1%). Efficacy and induction of remission were physicians' most common reasons for AT choice. Dislike of injections/infusions was the most common reason for eligible patients not receiving biologic therapy. Numerically, non-responders (both AT-naïve and AT-experienced) had more symptoms, overall pain and fatigue, and lower HRQoL scores than responders. Before (2017-2018) and during the pandemic (2020-2021), over half of patients with UC did not respond to AT. Non-responders carried a high burden of disease. Alternative therapies are urgently needed to treat UC.
