BACKGROUND/AIMS: Carotegrast methyl is a novel small-molecule drug that inhibits α4 integrin. It is prescribed for up to 6 months in patients with moderate ulcerative colitis who have demonstrated an inadequate response to or intolerance of 5-aminosalicylic acid. However, only a few clinical trials have been conducted to assess its effectiveness. This study aimed to evaluate the efficacy and safety of carotegrast methyl in patients with ulcerative colitis.
METHODS: This multicenter retrospective study included patients with active ulcerative colitis treated with carotegrast methyl between March 2022 and October 2024. The primary outcome was the clinical remission rate following treatment with carotegrast methyl. Secondary outcomes included the clinical response rate, predictors of clinical remission, ulcerative colitis relapse rate after discontinuing carotegrast methyl, and incidence of adverse events.
RESULTS: This study included 62 patients who received carotegrast methyl treatment. The median duration of administration was 84 days, with 48.4% of patients achieving clinical remission at the time of carotegrast methyl discontinuation. In 42 patients with corticosteroid/advanced therapies-naive disease, the clinical remission rate was 54.8%. Multivariate analysis identified the baseline partial Mayo score as an independent predictor of clinical remission. Among those who achieved clinical remission, 34.8% experienced a relapse with a median time to relapse of 152 days. Adverse events occurred in 8 patients, but none were serious.
CONCLUSIONS: Carotegrast methyl demonstrated good efficacy and safety, potentially benefiting patients with low baseline disease activity. This drug may be a useful treatment option to consider before systemic corticosteroid therapy for ulcerative colitis.
