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). Here, we evaluate the impact of etrasimod 2 mg QD on health-related quality of life (HRQoL) in patients with UC. This post hoc analysis used data from the Phase 3 randomized controlled trials, ELEVATE UC 52 and ELEVATE UC 12. HRQoL measures included: Inflammatory Bowel Disease Questionnaire (IBDQ), 36-Item Short Form Survey (SF-36), and Work Productivity and Activity Impairment Questionnaire: Ulcerative Colitis (WPAI:UC) completed at baseline, Week 12 (both trials), and Week 52 (ELEVATE UC 52 only). For IBDQ analyses, patients were stratified by prior exposure to biologics/Janus kinase inhibitors (JAKi) and baseline modified Mayo score (MMS; 4-6 or 7-9). Generally, significantly greater proportions of patients receiving etrasimod (N = 527) vs placebo (N = 260) achieved IBDQ remission (IBDQ total score ≥170) and IBDQ response (IBDQ total score increase from baseline ≥16), with significant improvement in all IBDQ domain scores at Week 12 and maintained through Week 52. Significant differences in IBDQ remission and IBDQ response rates between etrasimod and placebo were more consistent among biologic/JAKi-naive patients vs those who were biologic/JAKi-experienced and in those with baseline MMS 7-9 vs 4-6. Significant improvements were observed in several SF-36 domain and summary scores and WPAI:UC domain scores at Week 12 and Week 52. Etrasimod 2 mg QD demonstrated significant and clinically meaningful improvements across multiple HRQoL measures, including WPAI, vs placebo. ClinicalTrials.gov: NCT03945188; NCT03996369.
