Effectiveness and safety of ustekinumab maintenance therapy in 103 patients with real-world ulcerative colitis: A GETAID multicentre cohort study

Abstract : Background: Phase III trials have demonstrated the efficacy and safety of ustekinumab in moderate-to-severe ulcerative colitis (UC), but no real-life long-term data is currently available. Methods: From January to September 2019, all consecutive patients with active UC treated with ustekinumab in a GETAID centre were included. Patients were evaluated at week 52. Remission was defined by a partial Mayo Clinic score ≤ 2. The aim of the present study was to assess long-term effectiveness and safety of usteki numab in UC. Results: 103 UC patients (62 men; mean age: 41.2 ± 16.2 years; 52% pancolitis E3) were included in 21 centres. History of immunomodulator, anti-TNF and vedolizumab therapies was noted in 84.5%, 99.0% and 85.4% of the cases, respectively. At week 54, 44 (43%) patients discontinued ustekinumab, for lack of efficacy (n=41), pregnancy (n=1), persistence of eczematiform lesions (n=1) or personal decision (n=1). Cumulative probabilities of ustekinumab persistence were 96.1%, 81.6%, 71.7%, and 58.4% after 3, 6, 9, and 12 months, respectively. In multivariate analysis, a CRP>5 mg/L at week 0 (OR=2.91, CI95%[1.15–7.36]; p=0.02) and concomitant steroids at week 0 (OR=3.05, CI95%[1.30–7.14]; p=0.01) were significantly associated with ustekinumab discontinuation within one year. The overall rate of steroid-free clinical remission at week 52 was 32% of whom 71% had null rectal bleeding and stool frequency Downloaded from https://academic.oup.com/ecco-jcc/article/15/Supplement_1/S486/6286779 by guest on 03 February 2022 Abstracts of the 16th Congress of ECCO - European Crohn's and Colitis Organisation S487 subscores. Ten patients (9.7%) underwent colectomy within a median of 6.7 [4.3–10.6] months. Adverse events were observed in 15 (16.9%) patients, of whom 4 (4.5%) had severe adverse events including three patients with exacerbation of UC leading to hospitalization, and a 62 years-old men who died from a myocardial infarction four months after ustekinumab initiation. Conclusion: In this real-world cohort study that included patients with refractory ulcerative colitis to multiple therapies, more than one-half of patients were still treated by ustekinumab and one-third were in steroid-free clinical remission, after 52 weeks.
