Abstract Background An unmet therapeutic need remains in patients with ulcerative colitis (UC). U-ACHIEVE is one of two phase 3 induction trials evaluating the safety and efficacy of the selective Janus kinase–1 inhibitor upadacitinib (UPA) 45 mg once daily (QD) in adults with UC. Methods U-ACHIEVE is a multicentre, double-blind, placebo (PBO)–controlled trial (NCT02819635) that randomized patients with moderately to severely active UC 2:1 to UPA 45 mg QD or PBO for 8 weeks. Patients were stratified by response to biologic therapy (inadequate vs non–inadequate responder), baseline corticosteroid use (yes or no), and baseline adapted Mayo score (≤7 or >7). The primary endpoint was proportion of patients achieving clinical remission (per adapted Mayo Score) at week 8.Ranked secondary endpoints included endoscopic improvement, endoscopic remission, and clinical response per adapted Mayo Score at week 8; clinical response per partial adapted Mayo Score at week 2; and histologic-endoscopic mucosal improvement at week 8. Non-responder imputation incorporating multiple imputations for missing data due to COVID-19 are reported. Safety was assessed through week 8. Results 474 patients were randomized (UPA, n=319; PBO, n=155). Baseline characteristics were well balanced between groups (Table 1). A significantly higher proportion of patients receiving UPA (26.1%) vs PBO (4.8%) achieved clinical remission at week 8 (adjusted treatment difference [95% CI], 21.6% [15.8, 27.4]; P<0.001; Figure 1). For all ranked secondary endpoints, UPA was superior to PBO (P<0.001; Figure 1). A significant difference in clinical response favouring UPA vs PBO was seen as early as week 2 (60.1% vs 27.3%) and was sustained over 8 weeks (79.0% vs 41.6%; Figure 2). There were more serious adverse events (AEs), severe AEs, and AEs leading to study drug discontinuation with PBO (Table 2). The most common AEs were acne, creatine phosphokinase elevation, and nasopharyngitis with UPA and worsening of UC and anaemia with PBO. Incidence of serious infection was similar between UPA and PBO. Neutropenia and lymphopenia were reported more frequently with UPA vs PBO (Table 2).No adjudicated gastrointestinal perforation, major cardiovascular AEs, or thrombotic events and no active tuberculosis, malignancy, or deaths were reported. Conclusion In patients with moderately to severely active UC, UPA 45 mg QD induction therapy was superior to PBO in inducing clinical remission/response, and endoscopic remission/response over 8 weeks; responses were significant and rapid. UPA 45 mg QD was well tolerated; safety was comparable with the known safety profile of UPA, and no new safety signals were identified.

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

Abstract Background Tofacitinib (TFC) is an oral, small-molecule Janus kinase inhibitor, which was recently approved for moderate to severe ulcerative colitis (UC). The aim of the current real-life study was to determine efficacy of TFC induction therapy regarding the clinical response and remission in patients with active UC. We evaluated short-term efficacy data in a Hungarian cohort with prior exposure to other biological agents such as anti-TNF drugs and vedolizumab. Methods In this single-centre retrospective study, patients with TFC introduction were included. Since January 2019, a total of 16 patients received an oral TFC induction therapy in a dose of 10 mg twice daily for 8 weeks. Endoscopic activity was evaluated by endoscopic Mayo (eMayo) score before the introduction of TFC and in case of an inadequate therapeutic response to the 5-mg-therapy to confirm therapeutic decision-making. Based on the evaluation of clinical symptoms and laboratory parameters, we either kept the dosage or reduced the dose to 5 mg according to local regulations. We also collected data from the 16. and 24. weeks of the therapy. Primary endpoints were a clinical response (as a reduction in partial Mayo Score [pMayo] by minimum 3 points) or remission (as a Mayo score of the maximum of 2 points and without blood in stool) at week 8. Results Sixteen patients had received the induction therapy (mean age: 36 years, 7 males and 9 females) in our centre. After 8 weeks, 12 (75%) patients responded to the TFC induction therapy and 6 (37.5%) of them were in remission. Four patients were primary non-responders (25%). Corticosteroid therapy (18 ± 7 mg) was required during the induction in 4 responder cases, which could be stepped down by week 8. As a continuous maintenance therapy, 4 patients have already reached the 16th week and 8 have completed the 24th week. By the end of the follow-up, 12 patients responded and 10 was in remission. During the observation period, 3 patients had to remain on 10 mg TFC dose, 6 patients required dose escalation from 5 mg to 10 mg and 5 mg was sufficient in case of only 3 patients after the introduction. Endoscopic activity showed a moderate decrease from 2.5 ± 0.5 eMayo score to 2 ± 1 (n = 7) until week 16. In respect the responder patients, CRP levels decreased from the mean of 7.23 to 5.02. No serious side-effects were observed during the follow-up. Conclusion After the 8-week TFC induction therapy, the response rate was high and only every fourth patients were non-responder. A low number of patients had adequate reactions to the 5 mg-therapy after the introduction, but TFC is effective with dose-escalation in respect of clinical response and remission in patients with UC, who have had an inadequate response to previous biological therapy.

Abstract Background A significant proportion of patients with moderate to severe ulcerative colitis (UC) do not respond to therapy, which includes thiopurines, glucocorticoids, and antagonists to tumour necrosis factor-α and integrin. Tofacitinib, a Janus Kinase inhibitor, has emerged as an efficacious and safe treatment for moderate to severe ulcerative colitis. However, it is not known if this efficacy translates into real-life effectiveness in a regular clinical practice. Aims We aimed to assess the rate of clinical response and clinical remission at 3 and 6 months after tofacitinib initiation. Secondary endpoints included rate of biomarker normalization, corticosteroids-free clinical remission and severe infections. Methods We conducted a multi-center retrospective observational study of adult patients with active UC started on tofacitinib from January 1, 2015 to October 1, 2019 at the McGill University Health Center and Hotel-Dieu de Lévis. A positive clinical response was defined as a decrease of ≥3 in the partial Mayo score. Clinical remission was defined as partial Mayo score of ≤2. Biomarker normalization was defined as fecal calprotectin ≤250ug/g. Severe infection was defined as an infection requiring hospitalization. Results During the study period, 40 patients with UC were started on tofacitinib. Amongst the patients, 85% (n=34) had failed ≥1 biologic and 50% (n=20) had failed ≥3 biologics. At the time of this preliminary analysis, 38 patients had undergone 3 months of treatment and 30 patients had undergone 6 months of treatment. At 3 months, a clinical response was seen in 89.5% of patients (n=34) and clinical remission occurred in 63.2% (n=24). At 6 months, clinical response occurred in 73.3% of patients (n=22) and clinical remission was sustained in 53.33% (n=16). Biochemical normalization occurred in 29.0% (n=11) and 30.0% (n=9) at 3 and 6 months, respectively. Additionally, 63.2% (n=24) and 43.3% of patients (n=13) achieved steroid-free clinical remission at 3 and 6 months, respectively. In the interim, one patient developed a serious infection requiring discontinuation of drug. Conclusions Our preliminary analysis demonstrates that in a real-life setting, tofacitinib is an effective treatment for inducing clinical remission in refractory UC patients. Further data will be complied to better assess the efficacy over a longer follow up. Funding Agencies None

Abstract Background Tofacitinib is an orally active, small-molecule Janus kinase inhibitor, recently approved for the treatment of moderate to severe ulcerative colitis (UC) refractory to corticosteroid. However, currently, there is inadequate evidence for efficacy of Tofacitinib in UC patients. Therefore, our objective was to evaluate the efficacy and safety of Tofacitinib for inducing and maintaining remission in UC patients. Methods In a single-centre retrospective setting, 71 consecutive patients with UC who had failed to respond to corticosteroid or biologics were included. All patients had received 10mg Tofacitinib orally twice daily for at least 8 weeks as remission induction therapy and then, the responders received 5mg twice daily as maintenance therapy for up to 26 weeks. The clinical response and adverse events were evaluated at weeks 8 (induction) and 26 (maintenance). UC activity was assessed by the partial Mayo score. Clinical remission was defined as p-Mayo score ≤1 and the bleeding subscore = 0. Clinical response was defined as p-Mayo score ≤4 and a decrease of ≥3 points relative to baseline. Furthermore, the cumulative remission rates up to 26 weeks were determined by the Kaplan–Meier survival analysis. Results At week 8, 24 of 71 patients (33.8%) achieved clinical remission and 20 (28.2%) achieved response level. The mean p-Mayo score fell from 5.8 ± 1.1 at entry to 3.5 ± 2.3 at week 2 (p < 0.01) and 2.3 ± 1.9 at week 8 (P<0.01). The average total cholesterol increased from 180.8 ± 36.0 mg/dl at entry to 206.8±39.3 mg/dl (p < 0.01). In anti-tumour necrosis factor (TNF)-α or vedolizumab (VDZ) naïve subgroup (n = 14), 8 patients (57.1%) achieved response level, while in biologic failure subgroup (n = 57), 36 patients (63.2%) achieved response level. In single biologic failure subgroup (n = 27), 19 patients (70.4%), in double biologics failure subgroup, 14 of 24 patients (58.3%), and in 3 biologics failure subgroup, 3 of 6 patients (50.0%) achieved response level, showing a decrease in the efficacy of Tofacitinib in patients who had failed more than one biologic. Furthermore, of the 25 patients followed for 26 weeks, 23 (92.0%) sustained remission at week 16 and 19 (76.0%) at week 26. Herpes virus infection occurred in 4 patients. The increase in total cholesterol was observed in 68.8% of the patients. Conclusion Our retrospective efficacy assessment indicated that Tofacitinib was effective and safe for inducing and maintaining remission in corticosteroid refractory UC patients, regardless of biologic naïve or failure background. The efficacy of 10mg twice daily was rapid and observed within 2 weeks of starting the treatment.

Abstract Objectives To study the role of faecal microbiota transplantation [FMT] in maintenance of remission in ulcerative colitis [UC]. Methods In this pilot study, patients with UC in clinical remission achieved after multi-session FMT were randomly allocated to either maintenance FMT or placebo colonoscopic infusion every 8 weeks, for 48 weeks. The standard of care [SOC] therapy was continued in all patients. The primary endpoint was maintenance of steroid-free clinical remission [Mayo score ≤2, all subscores ≤1] at Week 48. Secondary endpoints were achievement of endoscopic remission [endoscopic Mayo score 0] and histological remission [Nancy grade 0, 1] at Week 48. Results In all, 61 patients in clinical remission were randomised to receive either FMT [n = 31] or placebo [n = 30]. The primary outcome was achieved in 27/31 [87.1%] patients allocated FMT versus 20/30 [66.7%] patients assigned placebo [p = 0.111]. Secondary endpoints of endoscopic remission (FMT: 18/31 [58.1%] versus placebo: 8/30 [26.7%], p = 0.026) and histological remission (FMT: 14/31 [45.2%] versus placebo: 5/30 [16.7%], p = 0. 033) were achieved in a significantly higher number of patients with FMT. Three patients receiving FMT [9.7%] and 8 patients on placebo [26.7%] relapsed. There were no serious adverse events necessitating discontinuation in patients on FMT; one patient who relapsed on placebo required colectomy. Conclusions Maintenance FMT in patients who are in clinical remission may help sustain clinical, endoscopic and histological remission in patients with UC.

Introduction. Treatment of patients with ulcerative colitis (UC) requires continuous anti-relapse therapy. Mesalazines are the firstline disease-modifying drugs for the treatment of mild to moderate UC to manage exacerbations and to induce and maintain remission.This paper is aimed at comparing the efficacy of treatment of patients with pancolitis and left-sided ulcerative colitis of moderate severity, who received MMX mesalazine as monotherapy and MMX mesalazine combined with mesalazines in the form of microclysters and suppositories.Materials and methods. A comparative clinical evaluation of the outcomes of treatment of patients with moderate UC who received MMX mesalazine as monotherapy (group 1) and MMX mesalazine combined with topical mesalazine (microclysters, suppositories) (group 2) was carried out. 40 patients with UC (group 1) and 46 (group 2) were examined.Results and discussion. Two weeks after MMX mesalazine therapy initiation, 92.8% of patients in group 1 responded to MMX mesalazine therapy and continued using the drugs as monotherapy (without microclysters and suppositories). In group 1, 95.6% of patients responded to MMX mesalazine therapy and continued treatment with topical mesalazines (microclysters and suppositories). At week 12, 54.3% of 35 patients in group 1, who responded to MMX mesalazine therapy, achieved clinical remission, 45.7% achieved clinical endoscopic remission. The Mayo Score decreased from 8.0 ± 0.17 to 2.3 ± 0.3 points. At week 12, 57.1% of patients with UC in group 2, who responded to MMX mesalazine therapy, achieved clinical remission, and 42.9% achieved clinical and endoscopic remission. The Mayo Score decreased from 7.85 ± 0.14 to 2.4 ± 0.3 points. There was no statistically significant difference in the level of laboratory findings between the groups of patients at 12 weeks and at 52 weeks (p> 0.05).Conclusion. The long-term continuous administration of MMX mesalazine in patients with pancolitis and left-sided ulcerative colitis of moderate severity as monotherapy during the year is comparable in its efficacy with combined MMX mesalazine therapy and topical forms of mesalazine.

Abstract Background Tofacitinib, an oral small molecule Janus kinase inhibitor, has been approved in 2018 for the treatment of moderate to severe ulcerative colitis (UC) in Europe. We report on real-world short-term efficacy and safety data from a multicenter Belgium refractory cohort of UC patients with prior exposure to both anti-TNFα and vedolizumab. Methods This is an observational, national, retrospective multicentre study including all UC active patients started on tofacitinib (10 mg BID) from 25 centres in Belgium between November 2018 and August 2019. Prospectively collected data were retrospectively analysed according to intention to treat. Primary endpoints were clinical and endoscopic response and remission rates at weeks 8 and 16. Clinical response and remission were defined as a reduction in the Modified Clinical Mayo score (rectal bleeding, stool frequency) of ≥2 and ≤1, respectively. Endoscopic response and remission were defined as a reduction in Endoscopic Mayo score of ≥1 and ≤1, respectively. Complete endoscopic remission was defined as an Endoscopic Mayo score of 0. Descriptive statistics and Wilcoxon signed-rank test were calculated using Medcal 19.1. Results Demographic and baseline data of the 70 included patients are presented in Table 1. Of note is that nearly all patients were refractory to at least one anti-TNF and vedolizumab. Median follow-up was 16 weeks (IQR 13–26). Fifty-four per cent (38/70) of patients required prolonged induction at 10mg BID. Clinical evaluation was available in all patients at week 8 and 49 patients at week 16, while endoscopic data were available in 52 patients and 42 at weeks 8 and 16, respectively. Clinical response and remission, and endoscopic response and remission at weeks 8 and 16 are presented in Figures 1 and 2. Fifty per cent (21/42) of the patients under steroids at baseline could have stopped steroids at 16 weeks. Median baseline Modified Mayo score (rectal bleeding, stool frequency and endoscopy) decreased from 7 (IQR 5–8) to 4 (IQR 2–7) after 8 weeks (n = 49) (p < 0.0001), and down to 2 (IQR 1–5) at week 16 (n = 40) (p < 0.0001). Median CRP significantly decreased from baseline (5.3 mg/l, IQR [1.9–16.8]) to 1 mg/l at week 8 (IQR 0.5–6.2) (n = 49) (p = 0.003). Tofacitinib was well tolerated with only 1 reported case of single dermatome herpes zoster and no case of venous thromboembolism. Conclusion Tofacitinib very effectively induced short-term clinical and endoscopic response and remission even in a refractory cohort of patients with UC in a real-world clinical setting. During this short-term follow-up, tofacitinib was well tolerated with respect to adverse events.

Abstract Background Total inhibition of IL-6 or its receptor represents a potent anti-inflammatory therapy with considerable side effects. Selective targeting IL-6 trans-signalling may have safety advantages that differentiates it from current pan-IL-6 inhibitors. We evaluated the efficacy and safety of olamkicept, a soluble gp130-Fc fusion protein that binds to the IL-6 and soluble IL-6 receptor complex, as induction therapy for active ulcerative colitis (UC). Methods This multi-national, randomized, double-blind, placebo-controlled phase 2 trial (NCT03235752) enrolled patients with active UC (full Mayo score ≥5, rectal bleeding (RB) score ≥1, endoscopy score (ES) ≥2) with an inadequate response to at least conventional therapy, in a 1:1:1 ratio to receive either placebo, olamkicept 300 mg or 600 mg biweekly for 12 weeks. Primary efficacy endpoint was clinical response (decrease in Mayo score from baseline ≥3 and ≥30%, including RB ≤1 or RB decrease ≥1) at week 12. Secondary endpoints were mucosal healing (ES 0 or 1) and clinical remission (Mayo score ≤2, with no subscore >1 and RB=0). The efficacy endpoints were analysed by logistic regression. All p-values were 2-sided without adjustment for multiplicity. Results Of 91 treated patients (30 in placebo, 31 in olamkicept 300 mg group and 30 in 600 mg group), 88 patients (29:30:29) were evaluable for efficacy. Baseline disease and demographic characteristics were similar among the groups (Table 1). Most patients (94.5%) were bio-naïve. The percentage of patients achieving clinical response at week 12 was significantly greater for olamkicept 600 mg than placebo (58.6% vs 34.5%, P=0.032). Clinical remission at week 12 occurred in 0% (placebo), 6.7% (olamkicept 300 mg) and 20.7% (olamkicept 600 mg, P<0.001) of patients. Mucosal healing at week 12 occurred in 3.4%, 10% and 34.5% (P<0.001) of patients, respectively (Figure 1). Incidence of treatment emergent adverse events (TEAEs) was similar across the groups. The most common TEAEs included upper respiratory tract infection, increased AST levels, and increased urine bilirubin levels, which were mild to moderate and mostly transient. Serious adverse events (SAEs) were reported in 6.7%, 3.2% and 3.3% of patients, respectively. There were no deaths, or other severe AEs associated with current IL-6 inhibitors, such as perforations, severe infections, neutropenia or thrombocytopenia. Conclusion Biweekly 600 mg olamkicept induction therapy demonstrated clinical efficacy with respect to achieving clinical response, clinical remission and mucosal healing in patients with active UC. Olamkicept was well tolerated with a favourable safety profile. The positive results of this phase 2 study support further development of olamkicept in IBD.

Abstract Background Upadacitinib (UPA) is a selective and reversible Janus kinase inhibitor.U-ACCOMPLISH is one of two phase 3 induction trials that evaluated the safety and efficacy of UPA 45 mg once daily (QD) in adults with ulcerative colitis (UC). Methods U-ACCOMPLISH was a multicentre, randomized, double-blind, placebo-controlled trial (NCT03653026) that enrolled patients with moderate-to-severe UC (defined as adapted Mayo score 5–9 with centrally read endoscopic score 2–3) who had inadequate response, loss of response, or intolerance to aminosalicylates, immunosuppressants, corticosteroids and/or biologics. Patients were randomized 2:1 to UPA 45 mg QD or placebo (PBO) for 8 weeks. At week 8, responders entered the maintenance phase and non-responders entered the extended treatment period to receive open-label UPA 45 mg QD for additional 8 weeks.The primary endpoint (clinical remission per adapted Mayo Score) and ranked secondary endpoints including symptomatic, endoscopic– histologic evaluations from the 8-week PBO-controlled period are reported here. Non-responder imputation incorporating multiple imputation for missing data due to COVID-19 are reported. Results 522 patients were randomized (UPA, n=345; PBO, n=177); the intent-to-treat population included 341 patients in UPA and 174 patients in PBO group. Baseline demographics and disease characteristics were similar between groups; 50.7% and 51.1% were biologic inadequate responders in UPA and PBO groups, respectively (Table 1). A significantly higher proportion of patients receiving UPA 45 mg QD (33.5%) versus PBO (4.1%) achieved the primary endpoint (adjusted treatment difference: 29.0% [23.2, 34.7]; P<0.001). A significantly higher proportion of patients receiving UPA versus PBO also achieved all ranked secondary endpoints (all P<0.001; Figure 1).Serious adverse events were reported by 3.2% and 4.5% of patients in UPA and PBO groups, respectively (Table 2). Similar rates of serious infection were observed in both groups (0.6%); 2 events each of herpes zoster and opportunistic infection were reported in UPA group. No active tuberculosis, malignancy, adjudicated major adverse cardiovascular events, or deaths were reported in the study. One patient with venous thromboembolism (deep vein thrombosis and pulmonary embolism) and 1 patient with gastrointestinal perforation were reported in the placebo group. Conclusion In U-ACCOMPLISH, 8-week UPA 45 mg QD induction treatment led to statistically significant improvements in clinical, endoscopic, and combined endoscopic-histologic endpoints. The treatment was well tolerated, and the safety profile and AE prevalence was comparable with previous studies of UPA with no new safety signals identified.
