• Abstract Background Etrasimod is an oral, once-daily (QD), selective sphingosine 1-phosphate (S1P)1,4,5 receptor modulator for the treatment of moderately to severely active ulcerative colitis (UC). Previous work has shown age can impact treatment safety and efficacy in patients with inflammatory bowel disease.1 This post hoc analysis investigated the impact of age on the safety and efficacy of etrasimod in patients with UC in the phase 3 ELEVATE UC clinical programme. Methods Data pooled from the ELEVATE UC 52 (NCT03945188) and ELEVATE UC 12 (NCT03996369) trials were analysed in patients receiving etrasimod 2 mg QD and placebo. ELEVATE UC 52 had a treat-through design comprising a 12-week induction period followed by a 40-week maintenance period. ELEVATE UC 12 was a 12-week induction trial. Proportions and incidence rates (IRs) per 100 patient-years from pooled data of treatment-emergent adverse events (TEAEs) and events of interest were stratified by age (<40 years, 40–59 years, ≥60 years) and analysed in patients who received ≥1 dose of etrasimod or placebo. Efficacy analyses were evaluated in patients with baseline Modified Mayo score (MMS) 5–9 for the primary efficacy endpoint (clinical remission) and select secondary endpoints at Week 12 (both trials) and Week 52 (ELEVATE UC 52) stratified by age. Results There were 787 patients enrolled in the ELEVATE UC programme, of whom 420 (53.4%) were aged <40 years, 276 (35.1%) were aged 40–59 years and 91 (11.6%) were aged ≥60 years. The proportions and IRs of TEAEs and events of interest were mostly similar between age groups and treatment arms (Table). IRs of arthralgia, fatigue, hypertension and pyrexia were higher in older age groups, regardless of treatment arm. Serious AEs and AEs leading to treatment discontinuation were low and consistent across all age subgroups. Serious infections and infection events of interest were balanced across age groups and treatment arms. Regardless of age subgroup, significantly more patients treated with etrasimod 2 mg QD vs placebo achieved the primary and select secondary efficacy endpoints at Week 12 and Week 52 (Figure). Conclusion The safety profile of etrasimod 2 mg QD in the UC population was consistent across age groups, and with no new risks other than the estimated risks associated with increasing age.2 Patients receiving etrasimod in the ELEVATE UC programme showed significant clinical benefit as assessed by clinical remission, symptomatic remission and endoscopic improvement compared with placebo, regardless of age.
