INTRODUCTION: Rapid symptom relief is an important consideration for patients with ulcerative colitis (UC) experiencing a flare. Etrasimod is an oral, once-daily, selective sphingosine 1-phosphate1,4,5 receptor modulator for the treatment of moderately to severely active UC. We evaluated patient-reported symptomatic improvement from patients in the ELEVATE UC program.
METHODS: This study was a post-hoc analysis of pooled daily e-diary data from patients with moderately to severely active UC receiving etrasimod or placebo in the phase III ELEVATE UC 52 and ELEVATE UC 12 trials. During the 12-week induction periods, patients self-reported stool frequency and rectal bleeding on days 1-28. Daily symptomatic response and symptomatic remission were calculated (partial modified Mayo Score).
RESULTS: Overall, 787 patients (527 receiving etrasimod, 260 placebo) were included in the analysis. Etrasimod-treated patients had statistically significantly higher rates of symptomatic response and symptomatic remission during the first 28 days of therapy, with adjusted differences (95% CIs) reaching statistical significance from day 2 (5.6% [0.8-10.3], P = .022) to day 11 (4.7% [0.4-9.0], P = .034), respectively. In patients naïve to biologic/Janus kinase inhibitor therapy, symptomatic response was statistically significantly improved with etrasimod vs placebo from day 3 (8.9% [2.3-15.5], P = .008). Symptomatic improvement rates were similar with and without concomitant corticosteroid use.
CONCLUSIONS: In this post-hoc analysis, improvements in UC symptoms occurred in patients receiving etrasimod vs placebo from as early as day 2. These findings indicate a rapid onset of symptomatic effect with etrasimod treatment for moderately to severely active UC.
