SummaryBackgroundFilgotinib, an oral, once‐daily, Janus kinase 1 preferential inhibitor, is an approved treatment for moderately to severely active ulcerative colitis.AimsThe aim of this study is to assess the safety and efficacy of continued filgotinib therapy over ~4 years in the long‐term extension of the phase 2b/3 SELECTION trial (SELECTIONLTE; NCT02914535).MethodsIn this interim analysis of SELECTIONLTE, SELECTION completers (week 10 responders to filgotinib who completed the maintenance study) continued their assigned treatment (double‐blind filgotinib 200 mg [FIL200] or filgotinib 100 mg) and SELECTION week 10 non‐responders received open‐label FIL200. We assessed safety by adverse events (AEs), and efficacy by partial Mayo Clinic Score (pMCS), inflammatory biomarkers and health‐related quality of life (HRQoL). We compared safety and efficacy between achievers and non‐achievers of a multi‐component endpoint, comprehensive disease control (CDC), comprising symptomatic, endoscopic, inflammatory biomarker and HRQoL improvements.ResultsData for completers (n = 250) and non‐responders (n = 372) were reported for ≤202 weeks. AE occurrences were low and consistent with previous analyses. The as‐observed proportion of FIL200‐treated patients in pMCS, biomarker and HRQoL remission during SELECTIONLTE remained high among completers (week 144: 80.0%, 86.4% and 86.0%, respectively) and increased among non‐responders (week 192: 62.1%, 76.7% and 59.3%, respectively). Significantly higher proportions of CDC achievers at SELECTION week 58 achieved pMCS, IBDQ and corticosteroid‐free pMCS remission than non‐achievers, up to LTE week 96.ConclusionsFilgotinib induced and maintained symptomatic remission and improved HRQoL over 4 years. Safety results showed a proven long‐term benefit–risk profile. FIL200‐treated CDC achievers had better long‐term outcomes than non‐achievers.

Background Vedolizumab is an anti-α4β7 integrin antibody used to treat moderate to severe ulcerative colitis (UC) and Crohn’s disease (CD). This post hoc analysis of patient-reported outcomes (PROs) from the VISIBLE 1 (NCT02611830) and 2 (NCT02611817) phase 3 studies evaluated onset of treatment effect on patient-reported symptoms during 6-week vedolizumab induction. Methods Patient-reported stool frequency (SF) and rectal bleeding (RB) (UC Mayo score), and SF and abdominal pain (AP) in CD were collected via electronic diary from VISIBLE patients receiving one or more open-label intravenous (IV) vedolizumab induction doses (weeks 0 and 2). PRO data were analyzed using descriptive statistics. Results Data from 994 patients (UC 383, CD 611) showed mean ratings for all PROs declined consistently week-on-week from baseline through week 6, with early onset of improvement. By week 2, 22% of patients with UC reported RB improvement (≥1-point reduction in RB subscore, 7-day mean), rising to 45% by week 6. By week 6, 18% of patients with UC achieved SF improvement (SF subscore 0; 21% antitumor necrosis factor alpha [anti-TNFα] naive, 13% anti-TNFα experienced). SF improvement in patients with CD (reduction of ≥3 stools, 7-day mean) was achieved by 32% at week 6 (34% anti-TNFα naive, 30% anti-TNFα experienced). Fewer patients with CD reported severe/moderate AP at week 6 (5.1%/28.5%) than baseline (14.6%/61.5%). SF decline appeared greater and faster for anti-TNFα-naive vs. anti-TNFα-experienced patients (UC and CD). Conclusion Results indicate early onset of patient-reported UC and CD symptom improvement during vedolizumab IV induction in VISIBLE 1 and 2.

Abstract Background Filgotinib (FIL), an oral, once-daily, Janus kinase 1 inhibitor, was approved for Ulcerative Colitis (UC) treatment after the phase 2b/3 SELECTION trial (NCT02914522). In SELECTION, a greater proportion of FIL200 mg (FIL200)-treated than placebo-treated patients achieved comprehensive disease control (CDC), a stringent multi-component endpoint. We examined the long-term outcomes of achieving CDC in patients continuing on FIL200 in the ongoing long-term extension (LTE) study SELECTIONLTE (NCT02914535). Methods This interim analysis included adult patients with UC who completed SELECTION and received ≤144 weeks of FIL200 in the LTE (up to data cut-off 24/02/22). CDC (biomarker remission, endoscopic improvement, IBDQ remission and partial Mayo Clinic Score [pMCS] remission achieved concurrently) was assessed at SELECTION week 58 (LTE baseline [BL]). Mean pMCS and IBDQ score, use of corticosteroids (CS) and incidence of TEAEs and serious TEAEs in the LTE were compared between SELECTION CDC achievers and non-achievers. A mixed model for repeated measures was fitted on pMCS and IBDQ score, with CDC achiever status, study visit and the interaction between CDC achiever status and study visit as fixed effects; p values were nominal. Results We analysed 148 patients (CDC achievers, n=41; CDC non-achievers, n=107). Mean pMCS was stable in CDC achievers (0.44, LTE BL; 0.50, LTE week 144) and decreased in CDC non-achievers (1.49, LTE BL; 0.77, LTE week 144; Figure). Mean IBDQ score was stable in CDC achievers (204.05, LTE BL; 197.21, LTE week 144) and increased in CDC non-achievers (181.55, LTE BL; 196.37, LTE week 144; Figure). There was a significant beneficial effect of achieving CDC on pMCS and IBDQ score overall (pMCS: fixed effect estimate: −0.5542, p=0.0025; IBDQ score: fixed effect estimate: 13.1585, p=0.0042). There was a significant interaction between achieving CDC and study visit for IBDQ score (p=0.0183), with the benefit of achieving CDC lessening by week 144. Generally, a lower proportion of CDC achievers used CS than non-achievers; 2.4–7.3% of CDC achievers used CS vs 1.9–15.9% of CDC non-achievers. Incidence of TEAEs and serious TEAEs were stable over time and similar between CDC achievers and non-achievers. Conclusion Follow-up for ~3 years showed high levels of long-term benefit with continued FIL200 treatment. Achieving comprehensive disease control at the end of the randomized trial with FIL200 was associated with long-term efficacy, improved HRQoL and low overall use of CS. This may demonstrate the value of filgotinib-induced achievement of CDC in UC disease course. The safety profile of FIL200 was consistent between CDC achievers and non-achievers, suggesting an acceptable long-term benefit–risk profile.

Abstract Background Etrasimod is an oral, once-daily, selective sphingosine 1-phosphate (S1P)1,4,5 receptor modulator for the treatment of moderately to severely active ulcerative colitis (UC). Adverse events (AEs) pertaining to tolerability, laboratory and serious AEs are described elsewhere1,2; we present a post hoc analysis of the incidence, onset and duration of the most commonly occurring non-serious AEs in the etrasimod UC clinical programme. Methods Data from the pooled Placebo-controlled UC cohort, derived from the phase 2 OASIS (NCT02447302) and phase 3 ELEVATE UC 52 (NCT03945188) and ELEVATE UC 12 (NCT03996369) double-blind clinical trials, were included. Cohorts comprised OASIS and ELEVATE UC 12 12-week induction periods alongside the ELEVATE UC 52 12-week induction and 40-week maintenance periods utilising a "treat-through" design. Patients (pts) with moderately to severely active UC were eligible for the etrasimod UC clinical programme. Pts were randomised to etrasimod 1 mg once daily (QD; OASIS only), etrasimod 2 mg QD or placebo. Proportions and incidence rates (IRs) of non-serious AEs (MedDRA v24.1 Preferred Terms of headache, pyrexia, nausea, fatigue and dizziness) were analysed in the Placebo-controlled UC cohort. Results Among 943 pts (any dose of etrasimod, N=629 [288.1 pt years (PY)]; placebo, N=314 [115.1 PY]), there were 77, 36, 30, 15 and 23 headache, pyrexia, nausea, fatigue and dizziness AEs, respectively. All were non-serious and did not lead to treatment discontinuation, apart from one case of pyrexia in which early termination visits were incomplete. Proportions and IRs (per 100 PY) for headache and dizziness AEs were higher with etrasimod (any dose) vs placebo (IRs: 13.45 vs 8.63 and 6.52 vs 1.69, respectively); IRs for other non-serious AEs were similar in etrasimod (any dose) and placebo groups (Table). Onset of AEs varied over time and most AEs were short in duration (Figure shows onset and duration for headache and dizziness AEs). Most AEs were deemed not related to study treatment by the site investigator. Pts with dizziness on Days 1–3 had similar changes in heart rate vs those with dizziness after Day 3. No consistent trend in heart rate was observed in pts receiving etrasimod with early dizziness. Conclusion Among pts in the etrasimod UC clinical programme, all headache, pyrexia, nausea, fatigue and dizziness events were non-serious. IRs were similar for most non-serious AEs across treatment groups, excluding headache and dizziness. Most non-serious AEs were short in duration and judged as not related to study treatment, suggesting they may not impact on the overall tolerability of etrasimod. References 1. Sandborn WJ et al.

SummaryBackgroundUpadacitinib is an oral, selective Janus kinase inhibitor.AimTo assess the efficacy and safety of upadacitinib in patients with moderate‐to‐severe ulcerative colitis following 16‐week extended induction therapy, and 52‐week maintenance therapy in patients achieving clinical response after 16‐week extended induction therapyMethodsPatients without clinical response to 8 weeks' upadacitinib 45 mg once daily induction therapy in two induction trials were eligible for an additional 8 weeks of therapy. Patients achieving clinical response at Week 16 were subsequently re‐randomised (1:1) to upadacitinib 15 or 30 mg once daily for 52‐week maintenance therapy. Efficacy was assessed at induction Week 16 (integrated) and maintenance Week 52; safety was assessed throughout.ResultsOverall, 127/663 (19.2%) patients did not achieve clinical response to upadacitinib 45 mg at Week 8 and received an additional 8 weeks of therapy; 75/127 (59.1%) subsequently achieved clinical response at Week 16 and entered the maintenance trial. At Week 52, 26.5% of patients receiving upadacitinib 15 mg, and 43.6% receiving 30 mg, achieved clinical remission; efficacy was observed across all other endpoints with both doses. Herpes zoster rates increased with longer duration (16 weeks) of exposure to upadacitinib 45 mg during induction compared with the same population during the first 8 weeks. No other new safety signals were observed, and results are otherwise consistent with the known safety profile of upadacitinib.ConclusionsPatients without clinical response after 8 weeks' upadacitinib 45 mg induction therapy, may benefit from an additional 8 weeks of therapy.Clinical trial registration: NCT02819635; NCT03653026

Summary Background Filgotinib 200 mg (FIL200) is an approved treatment for adults with moderately to severely active ulcerative colitis (UC). Aim To report integrated safety data from the phase 2b/3 SELECTION study (NCT02914522) and its ongoing long‐term extension study SELECTIONLTE (NCT02914535). Methods Safety outcomes were analysed in adults with moderately to severely active UC who received FIL200, filgotinib 100 mg (FIL100) or placebo once daily throughout the 11‐week SELECTION induction study, the 47‐week SELECTION maintenance study (if applicable) and SELECTIONLTE (if applicable). Exposure‐adjusted incidence rates (EAIRs) per 100 censored patient‐years of exposure with 95% confidence intervals were reported for treatment‐emergent adverse events (AEs). Certain AE data were presented in subgroups, including age and prior biologic exposure status. Results This interim analysis included 1348 patients representing 3326.2 patient‐years of exposure. Baseline characteristics of patients entering SELECTION were similar across treatment groups. EAIRs for serious infection, thromboembolic events and major adverse cardiovascular events (MACE) were consistently low across treatment groups. Most patients with MACE had cardiovascular risk factors. The EAIR for herpes zoster was numerically higher for FIL200 than for placebo. Infection incidences were numerically higher in biologic‐experienced than biologic‐naive patients. Higher incidences of certain AEs in patients 65 years of age or older were as expected. Four deaths occurred, including three cardiovascular deaths, none of which was considered related to filgotinib. Conclusion FIL200 and FIL100 were well tolerated with no unexpected safety signals in patients with moderately to severely active UC, regardless of previous biologic exposure or age.

Abstract Background Crohn’s disease (CD) and ulcerative colitis (UC), together known as inflammatory bowel diseases (IBD), affect approximately seven million people globally. The continuous rise in IBD prevalence and the aging of populations will inevitably lead to an increasing use of health care resources. In parallel with these trends, continuing innovations in IBD therapeutics, diagnostics, and preventatives are creating more options for IBD patients seeking to reduce their disease burden. These trends pose an imminent burden on health care systems and require that we identify modifiable cost drivers in IBD care and develop strategies for delivering equitable and affordable care for all patients. Methods This Lancet Gastroenterology & Hepatology Commission, consisting of a diverse faculty of health care professionals with expertise in the field of IBD and health economists, was formed to deliver an extensive summary of the literature and discuss key topics on the costs and cost-effectiveness of treating IBD in the present, and how this is likely to look in the future. Furthermore, it offers suggestions for how to deliver affordable IBD care in the coming years. The report’s focus was on high-income countries in Europe, North America, Australia and New Zealand, and Asia. Results The Commission drew together a wide range of expertise to discuss the current costs of IBD care, the drivers of increasing costs, as well as how to deliver affordable care for IBD in the future. The key conclusions are that (i) increases in health care costs must be evaluated against improved disease control and reductions in indirect costs, and (ii) that overarching systems for data interoperability, registries, and big data approaches must be established for continuous assessment of effectiveness, costs, and cost-effectiveness of care. International collaborations should be sought in order to evaluate novel models of care (such as value-based health care, including integrated health care and participatory health care models), as well as to improve the education and training of clinicians, patients, and policymakers. Measures to reduce the costs of IBD care are summarised in Table 1. Conclusion Increases in health care costs must be evaluated against improved disease control and reductions in indirect costs. Evaluations should be systematically aligned between countries and regions. Detailed analysis of the current epidemiology and the likely effects of changing IBD management on disease course and socioeconomic outcomes is essential; and will become even more imperative in the era of precision medicine, where complex biotechnologies will require expensive analyses, highly skilled personnel, and drug development for what may sometimes be relatively small patient groups.

Abstract Background Improvement in clinical outcomes and normalisation of objective markers of inflammation, high-sensitivity C-reactive protein (hs-CRP) and faecal calprotectin (FCP), are considered treatment targets per STRIDE-II guidelines.1 We evaluated the effect of the oral selective Janus kinase inhibitor upadacitinib (UPA) on changes in hs-CRP, FCP, and clinical outcomes in patients with Crohn’s disease (CD). Methods In 2 phase 3, randomized, double-blind, placebo-controlled induction studies (U-EXCEL, NCT03345849; U-EXCEED, NCT03345836), patients with moderate-to-severe CD received 12-week treatment with UPA 45 mg (UPA45) once daily (QD) or placebo (PBO). Patients with clinical response to UPA45 were rerandomised in U-ENDURE (NCT03345823) to receive 52-week maintenance treatment with UPA 30 mg QD (UPA30), UPA 15 mg QD (UPA15), or PBO. Endpoints included marker normalisation (hs-CRP ≤ 5 mg/L, FCP ≤ 250 µg/g) in patients with elevated baseline marker levels, normal marker and clinical remission by Crohn’s Disease Activity Index (CDAI < 150) or very soft/liquid stool frequency (SF)/abdominal pain score (APS) (average daily SF ≤ 2.8 and average daily APS ≤ 1, neither greater than baseline), and ≥ 50% reduction from baseline in marker values with a decrease of at least 100 points in CDAI from baseline. Median changes from baseline in marker levels were also evaluated. Non-responder imputation with no special data handling for missing data due to COVID-19 was used. Results Of 1021 enrolled patients, 645 (63.2%) had elevated hs-CRP (> 5 mg/L) and 750 (73.5%) had elevated FCP (> 250 µg/g) levels at baseline. Significantly greater proportions of patients with elevated baseline marker levels achieved normalisation with UPA compared with PBO at week 12 (Fig 1A/B) and week 52 (Fig 2A/B; nominal P < .001 for all). Decreases in marker levels from baseline with UPA were observed as early as week 2 and were significantly greater than with PBO through week 12 (Fig 1C) and week 52 (Fig 2C; nominal P < .001 for all). Patients achieved clinical endpoints and improvements in markers at significantly higher rates with UPA45 vs PBO at week 12 (Fig 1D–F) and with UPA15 and UPA30 vs PBO at week 52 (Fig 2D–F; P < .001 for all). The safety profile of UPA in CD was previously reported and no new safety concerns were identified. Conclusion Improvements in clinical endpoints and normalisation of objective markers of inflammation were achieved as early as week 2 with UPA45 induction and sustained with UPA15 and UPA30 maintenance therapy in patients with CD. Median changes in hs-CRP and FCP with UPA support continued improvement of inflammation up to week 52. 1. Turner D., et al. Gastroenterology. 2021;160(5):1570–1583.

Abstract Background We evaluated the health-related quality of life (HRQoL) benefits of upadacitinib (UPA) induction and maintenance treatment in a phase 3 study of patients with ulcerative colitis (UC) across a broad range of patient-centered outcomes. Methods Patients received UPA 45 mg once daily or placebo as induction treatment for 8 weeks. Patients who achieved clinical response were rerandomized to receive once daily UPA 15 mg, 30 mg, or placebo as maintenance treatment for 52 weeks. The percentages of patients reporting a clinically meaningful within-person change from baseline in the Ulcerative Colitis Symptoms Questionnaire, Inflammatory Bowel Disease Questionnaire, Work Productivity and Impairment Questionnaire, 36-Item Short Form Survey, and European Quality of Life-5 Dimension 5 Levels were evaluated at weeks 2 and 8 of induction and at weeks 0 and 52 of maintenance. Results Significant improvements from baseline in all HRQoL measures except the Work Productivity and Impairment Questionnaire–absenteeism were achieved with UPA (P < .001) vs placebo as early as week 2 of induction. These improvements were sustained at week 52 with significantly more patients treated with either 15 mg or 30 mg UPA vs placebo achieving meaningful within-person change in the Ulcerative Colitis Symptoms Questionnaire; Inflammatory Bowel Disease Questionnaire; overall work impairment, presenteeism, and activity impairment; both 36-Item Short Form Survey Physical and Mental Component Summaries; and European Quality of Life-5 Dimension 5 Levels (P < .001). Conclusions Induction treatment with UPA 45 mg significantly improved HRQoL measures. A significantly higher percentage of patients who responded to induction treatment with UPA maintained clinically meaningful improvements consistently across a wide range of HRQoL outcomes after 52 weeks of maintenance therapy with UPA (15 mg and 30 mg) compared with placebo.

Abstract Background In patients with ulcerative colitis (UC), risks of infection and malignancies increase with age. Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of UC. This analysis assessed age as a risk factor for adverse events of special interest (AESI) in the tofacitinib UC clinical program. Methods Data were from phase 2 and 3 induction studies, a phase 3 maintenance study, and an open-label, long-term extension study. Efficacy and/or safety outcomes were analyzed in the Induction, Maintenance, and Overall Cohorts (patients who received ≥ 1 dose of tofacitinib), stratified by age. The effects of baseline demographic and disease-related factors on AESI incidence were assessed by Cox proportional-hazards regression analysis. Results In the Overall Cohort (1157 patients with ≤ 6.8 years’ tofacitinib treatment), age was a statistically significant predictor of herpes zoster (HZ), malignancies excluding nonmelanoma skin cancer (NMSC), and NMSC. Other statistically significant predictors included prior tumor necrosis factor inhibitor failure for HZ, NMSC, and opportunistic infection events, and prior duration of UC for malignancies excluding NMSC. In the Induction and Maintenance Cohorts, a higher proportion of tofacitinib-treated than placebo-treated patients (numerical difference) achieved the efficacy endpoints (endoscopic improvement, clinical remission, clinical response) across all age groups. Conclusions Older individuals receiving tofacitinib as induction and maintenance therapy to treat UC may have an increased risk of HZ, malignancies (excluding NMSC), and NMSC versus similarly treated younger patients, consistent with findings from the general population. Across all age groups, tofacitinib demonstrated greater efficacy than placebo as an induction and maintenance therapy.
