Abstract Background Patients with ulcerative colitis (UC) often do not respond to treatment or lose response over time, and thus switch between therapies with various mechanisms of action (MoAs).1 Filgotinib (FIL) is a once-daily, oral, Janus kinase 1 preferential inhibitor in development as a UC treatment. We assessed the efficacy of FIL in biologic (bio)-naïve and bio-experienced patients with UC, and in bio-experienced patients with failure of 1 or ≥2 biologics or 1 or 2 MoAs. Methods SELECTION (NCT02914522) was a phase 2b/3 double-blind, randomised, placebo-controlled trial comprising two induction studies and a maintenance study. Adults (18–75 years) with moderately to severely active UC were randomised 2:2:1 to FIL 200 mg, FIL 100 mg or placebo (PBO) once daily for 11 weeks in Induction Study A (bio-naïve) and B (bio-experienced). Patients in either clinical remission or Mayo Clinic Score (MCS) response at week 10 (responders) could enter the Maintenance Study. Responders who received induction FIL were re-randomised 2:1 to continue their induction regimen or PBO through week 58. Responders who received induction PBO continued PBO. We assessed clinical remission and MCS response at weeks 10 and 58 in bio-naïve patients and bio-experienced patients with failure of 1 or ≥2 biologics and 1 or 2 MoAs (TNF antagonists and vedolizumab). All p values for subgroup analyses are nominal. Results At week 10, clinical remission was achieved by a significantly higher proportion of bio-naïve and -experienced patients treated with FIL 200 mg than PBO (Figure 1a). A higher proportion of bio-experienced patients with 1 biologic or MoA failure treated with FIL 200 mg than PBO achieved clinical remission at week 10 (p<0.05); a smaller treatment effect was seen in patients with ≥2 biologic or 2 MoA failures (Figure 1b). None of these comparisons reached p<0.05 for FIL 100 mg. Higher proportions of patients treated with either dose of FIL than PBO achieved MCS response at week 10 in all (sub)groups (Figure 2). At week 58, higher proportions of bio-naïve and -experienced responders, and bio-experienced responders with ≥2 biologic or 2 MoA failures treated with maintenance FIL 200 mg than PBO achieved clinical remission (p<0.05) (Table 1). Higher proportions of responders treated with maintenance FIL 200 mg than PBO achieved MCS response at week 58 in all (sub)groups. Conclusion FIL 200 mg was effective in inducing and maintaining clinical remission in bio-naïve and -experienced patients. Induction results suggest FIL 200 mg is most effective in bio-naïve patients, and those who switch after failure of 1 biologic or MoA. Interpretation of week 58 data is limited by low patient numbers. Reference

Abstract Background Filgotinib (FIL) is a once-daily, oral, preferential Janus kinase 1 inhibitor in development for the treatment of inflammatory bowel disease. FIL for the treatment of moderately to severely active ulcerative colitis (UC) was evaluated in the phase 2b/3 randomized, double-blind, placebo (PBO)-controlled SELECTION study (NCT02914522). Long-term use of corticosteroids (CS) is associated with significant side effects. The aim of this post hoc analysis was to assess the CS-sparing effects of FIL in the SELECTION study. Methods Patients (18–75 years old) with moderately to severely active UC were randomized (2:2:1) to receive FIL 100 mg (n = 564), FIL 200 mg (n = 507) or PBO (n = 280) once daily orally for up to 11 weeks (induction study). At week 11, FIL induction responders were rerandomized 2:1 to continue their induction FIL dose or to receive PBO (maintenance study). CS use was kept stable up to week 14, at which point mandatory CS tapering occurred. CS could be resumed during the maintenance study; however, if the baseline CS dose was exceeded this was considered treatment failure. In this post hoc analysis, CS-free remission was defined as remission at week 58 (endoscopic subscore ≤ 1, rectal bleeding subscore = 0 and ≥ 1-point decrease in stool frequency subscore to achieve 0 or 1) without systemic or localized CS use that was indicated for UC in the previous 1, 3, 6 or 8 months. Results The baseline characteristics of patients in the maintenance study were similar across treatment groups (Table 1). Of the 92 patients receiving CS at maintenance baseline (week 11; maintenance week 0) who received FIL 200 mg during the maintenance study, 25 (27%) were in remission at week 58 and had been continuously CS-free for at least the previous 6 months (Table 2). The proportion of CS-free remitters in the FIL 200 mg group was consistently higher than with PBO (Table 2). In patients taking CS at maintenance baseline who had continued CS-use post baseline, lower median prednisone dosing was observed with FIL 200 mg than with PBO throughout the maintenance study (maximum difference at week 34 [maintenance week 23]: 5.0 mg vs 13.8 mg) (Figure 1). In SELECTION, a total of 199 patients received FIL 200 mg in the maintenance study, of whom 74 (37.2%) were in remission at week 58; of these 74 patients, 69 (93.2%) were continuously CS-free for at least the previous 6 months (Figure 2). Conclusion In this post hoc analysis of SELECTION maintenance study data, FIL 200 mg was effective in reducing and eliminating CS use through to week 58 in patients with moderately to severely active UC. The vast majority of patients taking FIL 200 mg who were in remission at week 58 had not taken CS in the previous 6 months.

Abstract Background Filgotinib (FIL) is a preferential Janus kinase 1 inhibitor in development for the treatment of inflammatory bowel disease. SELECTION was a phase 2b/3 randomized, double-blind, placebo (PBO)-controlled trial to evaluate FIL for the treatment of moderately to severely active ulcerative colitis (UC) (NCT02914522). The aim of this post hoc analysis was to assess the speed of improvement in patient-reported outcomes (PROs) during FIL treatment. Methods Eligible patients who were biologic-naïve or -experienced were enrolled in induction study A or induction study B, respectively. In each study, patients were randomized 2:2:1 to receive FIL 100 mg, FIL 200 mg or PBO once daily orally for 10 weeks. In this post hoc analysis, data from daily patient diaries up to day 15 of induction, including Mayo stool frequency subscores (SF; range, 0 [normal] to 3 [≥5 stools/day more than normal]) and rectal bleeding subscores (RB; range, 0 [no blood] to 3 [passing blood alone]), were used to evaluate the proportion of patients achieving predefined subscores or subscore reductions. Results Induction studies A and B comprised 659 and 689 patients, respectively. Baseline characteristics were similar across treatment groups within induction study A and within induction study B. In induction study A, more patients treated with FIL 200 mg vs PBO reported a reduction in SF of ≥1 from baseline as early as day 6 (FIL 200 mg, 35.8%; PBO, 20.6%, p<0.01) and every day from day 10 (Figure 1), and a reduction in RB of ≥1 from baseline as early as day 4 (FIL 200 mg, 36.9%; PBO, 23.7%; p<0.01) and every day from day 7 (Figure 2). In induction study B, more patients treated with FIL 200 mg vs PBO reported a reduction in SF of ≥1 from baseline as early as day 2 (FIL 200 mg, 21.6%; PBO, 12.1%; p<0.05) (Figure 3) and a reduction in RB of ≥1 from baseline as early as day 3 (FIL 200 mg, 29.5%; PBO, 17.6%; p<0.01) (Figure 4). More patients receiving FIL 200 mg vs PBO achieved the composite score of RB=0 and SF≤1 as early as day 9 in induction study A (FIL 200 mg, 18.8%; PBO, 9.5%, p<0.05). More patients receiving FIL 200 mg vs PBO achieved the composite score of RB=0 and SF≤1 as early as day 7 in induction study B (FIL 200 mg, 10.7%; PBO, 4.2%, p<0.05). Conclusion In this post hoc analysis of induction study data from SELECTION, improvements in SF and RB were observed within the first week of therapy with FIL 200 mg, compared with PBO, in patients with moderately to severely active UC. These data demonstrate that FIL 200 mg has rapid onset of action, as assessed by PROs, in both biologic-naïve and biologic-experienced patients.

Abstract Background Filgotinib (FIL) is an oral preferential Janus kinase (JAK) 1 inhibitor in development for the treatment of inflammatory diseases. FIL for the treatment of moderately to severely active ulcerative colitis (UC) was evaluated in the phase 2b/3, double-blind, placebo (PBO)-controlled SELECTION study (NCT02914522) and its long-term extension (LTE) study (NCT02914535). Here we report safety results from the FIL UC program. Methods Patients received FIL 100 mg, FIL 200 mg or PBO (2:2:1) once daily orally for up to 11 weeks for induction (cohort 1). At week 11, FIL induction responders were rerandomized 2:1 to continue FIL or receive PBO maintenance for 47 weeks (cohort 2). Week 10 non-responders and patients with worsening disease during the maintenance study were eligible for open-label FIL in the LTE. Patients completing the maintenance study could continue blinded dosing in the LTE. Cohort 3 comprised cohorts 1 and 2 and the LTE. Exposure-adjusted incidence rates (EAIRs) and exposure-adjusted event rates (EAERs) per 100 patient-years (PYs) were calculated for treatment-emergent adverse events (AEs) by treatment group in cohorts 1 and 2 (EAIR) and cohort 3 (EAER). Results In cohort 1, 1069 patients received FIL and 279 patients received PBO; baseline characteristics were generally similar across treatment groups (overall mean age, 43 years; mean UC duration, 8.4 years; mean Mayo Clinic Score, 9.0). EAIRs for AEs of interest were similar across treatment groups in cohorts 1 and 2 (Table 1). Treatment exposure for PBO, FIL 100 mg or FIL 200 mg in cohort 3 (i.e. cohorts 1 + 2 + the LTE) was 318, 360 and 1207 PYs, and median treatment duration was 12, 11 and 67 weeks, respectively. One case of pulmonary embolism occurred with FIL 200 mg induction and three venous thrombosis cases occurred with PBO maintenance/LTE (cohort 3) (Table 2). EAERs for all infections were similar across treatment groups, the most common being nasopharyngitis (Table 2). Opportunistic infections were rare. EAERs for serious infections were low across treatment groups (2.2 [PBO], 3.5 [FIL 100 mg], 2.2 [FIL 200 mg]), the most common being appendicitis (Table 2). EAERs for herpes zoster (HZ) were low in all treatment groups (0.3 [PBO], 0.3 [FIL 100 mg], 1.8 [FIL 200 mg]) (Table 2). HZ infections were cutaneous only and only one was serious. EAIRs for all infections in cohorts 1 and 2 were generally numerically higher for both PBO and FIL in patients over (vs under) 65 years old and in those with (vs without) biologic treatment failure (Figure 1). Conclusion FIL was well tolerated in patients with UC. Aggregation of AEs typical for pan-JAK inhibition was not observed, consistent with preferential JAK-1 inhibition with FIL.

Abstract Background Faecal microbiota transplantation (FMT) administered via the lower GI tract effectively induces remission in ulcerative colitis (UC). Orally administered FMT capsules may improve patient tolerability and facilitate maintenance therapy while it is unclear if pre-FMT antibiotics enhance therapeutic efficacy. Methods We performed a dual-centre randomised, double blind, placebo-controlled trial of oral lyophilised FMT in adults with mild-moderately active UC (total Mayo 4–10). All subjects received 2-weeks of pre-FMT antibiotics (amoxycillin, metronidazole and doxycycline) before 1:1 randomisation to either oral FMT (0.35g stool content per capsule from 1 of 2 healthy donors) or identical placebo for 8 weeks. Enforced tapering and cessation of corticosteroids was mandated. The primary endpoint was week 8 steroid-free clinical remission with endoscopic remission or response (total Mayo score ≤2 with subscores ≤ 1 for rectal bleeding, stool frequency and endoscopic appearance, and ≥1-point reduction from baseline in endoscopy subscore). Responders to FMT induction were re-randomised to either continue maintenance FMT or withdrawal of FMT with final outcomes assessed at week 56. Results Recruitment was paused due to the COVID-19 pandemic. 37 patients were randomised. Baseline patient and disease characteristics were balanced between the randomised groups. The primary outcome was achieved in 8/16 (50%) receiving FMT versus 3/19 (16%) receiving placebo (OR: 4.63; 95%CI: 1.74–12.30; P=0.002). Steroid-free clinical remission rates and endoscopic remission rates were 69% vs 26% (P=0.012) and 44% vs 16% (P=0.074) in the FMT and placebo arms, respectively. Reported SAE were worsening colitis (2 FMT, 1 placebo) and PR bleeding relating to previous anal surgery (placebo). Ten patients entered the maintenance withdrawal study. Steroid-free clinical, endoscopic and histologic remission was achieved in 4/4 patients who continued daily oral FMT, with all 6 patients randomised to FMT withdrawal having a flare of disease with a median time to relapse of 6 months. Conclusion Oral lyophilised FMT following antibiotic pre-treatment for mild-moderately active ulcerative colitis was associated with a significant increased rate of clinical remission with endoscopic remission or response versus antibiotic treatment alone at week 8. Pre-treatment antibiotics had an additive impact upon treatment efficacy compared with previous studies utilising FMT. Maintenance FMT therapy was associated with sustained clinical, endoscopic and histologic remission at week 56. Treatment was well tolerated and there were no new safety signals related to FMT therapy.

Abstract Background Anaemia is a frequent complication in patients with Crohn’s disease and ulcerative colitis (UC), and patients who respond to treatment generally show improvement in anaemia. Decrease in haemoglobin (Hgb) levels and anaemia may be associated with Janus kinase (JAK) inhibitors. Upadacitinib (UPA), an oral JAK1 selective inhibitor, has demonstrated favourable dose-dependent efficacy in patients with moderately to severely active UC.1 This analysis of data from the U-ACHIEVE study addressed effects of UPA treatment on Hgb levels in patients with UC. Methods U-ACHIEVE (NCT02819635) was a randomised, double-blind, placebo (PBO)-controlled phase 2b clinical trial. Adults with moderately to severely active UC were randomised to receive 7.5, 15, 30, or 45 mg UPA or PBO once daily (QD) for 8 weeks. Hgb levels were measured for all groups at baseline (BL) and weeks 2, 4, 6, and 8. Mean change from BL was calculated for each group. p-values for comparison between UPA and PBO groups were calculated using one-way ANOVA; no multiplicity adjustment was applied. Percentage of patients with Hgb values grade 2 (15–20 g/l Hgb decrease from BL), grade 3 (<80 g/l Hgb level or 21–29 g/l Hgb decrease from BL), and grade 4 (<70 g/l Hgb level or >29 g/l Hgb decrease BL) anaemia were determined for all treatment groups using the Common Terminology Criteria for Adverse Events version 5. Adverse events (AE) were reported by investigators. Results Included in the analysis were 250 patients (mean age ± SD, 42.3 ± 14.2 years; disease duration, 8.2 ± 2.5 years). At BL, most treatment groups had similar mean Hgb levels, except for the 15 mg UPA group, which had significantly lower Hgb levels vs. PBO group (Table). Increased or stable mean levels of Hgb at week 8 vs. BL were observed in most UPA treatment groups. The PBO group had the greatest decrease in Hgb vs. BL at week 8 compared with UPA treatment groups (Figure). Grade ≥2 anaemia was reported in 17.4% of patients receiving PBO and 14.4% of all patients receiving UPA (14.9%, 12.2%, 12.0%, and 17.9% of patients receiving 7.5, 15, 30, and 45 mg UPA, respectively). Grade ≥3 anaemia was reported in 8.7% of patients receiving PBO and 5% of all patients receiving UPA (6.4%, 6.1%, 6.0%, and 1.8% of patients receiving 7.5, 15, 30, and 45 mg UPA, respectively). One subject receiving 7.5 mg QD UPA had grade 4 anaemia. AE of anaemia was reported in 6.5% of patients receiving PBO and in 2.1%, 8.2%, and 3.8% of patients receiving 7.5, 15, and 30 mg UPA, respectively, but not in the 45 mg UPA group. Conclusion Decreased Hgb levels over time were observed more frequently in the PBO group. The maintenance of Hgb levels in patients receiving UPA was likely because of improvement of underlying UC.

Abstract Aims The SELECTION (NCT02914522) Induction Studies evaluated the efficacy/safety of filgotinib (FIL), a preferential JAK1 inhibitor, as induction therapy for patients (pts) with moderately to severely active ulcerative colitis (UC) who were biologic-naïve but failed conventional therapy (Induction Study A) or failed prior biologics (Induction Study B). Methods Pts were randomized 2:2:1 to once–daily FIL 200mg, FIL 100mg or placebo (PBO). The primary (clinical remission), key secondary (Mayo Clinic Score [MCS] remission, endoscopic remission, and histologic remission), and exploratory endpoints (MCS response and endoscopic improvement) were assessed at Week 10. Results In both studies, baseline demographics and disease characteristics were similar across treatment groups. In Study A, 659 pts were randomized and treated. Baseline mean MCS was 8.6 and 56% had a Mayo endoscopic subscore (ES)=3. A significantly higher proportion of biologic-naïve pts on FIL 200mg achieved clinical remission vs PBO and all key secondary endpoints (Table). In Study B, 689 pts were randomized and treated. Baseline mean MCS was 9.3 and 78% had ES=3. Prior treatment failures were: anti-TNF (86%), vedolizumab (52%) and both (dual-refractory; 43%). A significantly higher proportion of biologic-experienced pts on FIL 200mg achieved clinical remission vs PBO. In Studies A and B, a greater proportion of pts on FIL 200 mg achieved an MCS response and endoscopic improvement vs PBO. The rates of AEs, serious AEs and discontinuations due to AEs were similar across FIL and PBO groups during induction. In the PBO, FIL 100mg and FIL 200mg groups, serious infections occurred in 0.7%, 0.7% and 0.4% pts in Study A and 1.4%, 1.4% and 0.8% pts in Study B; H Zoster occurred in <1% in both groups for both cohorts. Conclusions SELECTION included a high proportion of dual-refractory pts, and pts with severe endoscopic disease. Both doses of FIL were well tolerated. Filgotinib 200mg was effective induction therapy for both biologic-naïve/-experienced pts with moderately to severely active UC. Funding Agencies None
