Abstract
BACKGROUND: Etrasimod is an oral, once daily (QD), selective sphingosine 1-phosphate1,4,5 receptor modulator for the treatment of moderately to severely active ulcerative colitis (UC). We assessed the benefit of etrasimod monotherapy and the impact of concomitant corticosteroids (CS) and/or 5-aminosalicylates (5-ASA) therapy.
METHODS: In ELEVATE UC 52 and ELEVATE UC 12, patients with moderately to severely active UC were randomized 2:1 to etrasimod 2 mg QD or placebo for 52 and 12 weeks, respectively. Oral CS or 5-ASA were allowed at baseline. Patients in the monotherapy subgroup received etrasimod or placebo without concomitant CS and/or 5-ASA at baseline. Predefined primary (clinical remission) and key secondary efficacy endpoints aligned with those from both trials and were assessed at Week 12 and Week 52. Safety was assessed up to Week 52.
RESULTS: Clinical remission rates at Weeks 12 and 52 were significantly higher for etrasimod compared with placebo in patients receiving monotherapy (Week 12: 26.2% vs 4.8%; Week 52: 35.7% vs 4.0%). Differences vs placebo were statistically significant for all predefined endpoints at both time points in patients receiving monotherapy or etrasimod with concomitant 5-ASA only (all P < .05); numerical differences, due to small sample sizes, vs placebo were observed for all endpoints in the CS only and CS + 5-ASA subgroups. Safety was consistent with the overall population.
CONCLUSIONS: Etrasimod monotherapy showed consistent efficacy and safety vs placebo; no apparent benefit was observed with concomitant CS and/or 5-ASA in patients receiving etrasimod.
