ABSTRACTObjective: Ulcerative colitis (UC) is an idiopathic, chronic inflammatory disease of the large intestine, usually involving the rectum. During the lastdecade, clinical trials have shown adalimumab (ADA) and infliximab (IFX) to be efficacious in inducing and maintaining remission for moderate tosevere UC refractory to the conventional therapies. The purpose of this study was to compare the efficacy and safety of ADA and IFX for inductionremission in Iraqi patients with moderately to severely active UC.Methods: A total of 50 patients with moderate to severe UC, who were refractory to concurrent treatment with oral corticosteroids and/or immunesuppressants, were randomly assigned in 1:1 ratio to receive either ADA (160/80 mg, subcutaneous) or IFX (5 mg/kg, intravenous) during theinduction phase (8 weeks). Primary efficacy endpoint was clinical remission at week 8. Secondary efficacy endpoints were the clinical response,mucosal healing, subscores indicative of mild disease (rectal bleeding subscore [RBS], physician’s global assessment [PGA] subscore, and stoolfrequency subscore [SFS]). Partial Mayo score was also evaluated in addition to the inflammatory bowel disease questionnaire (IBDQ). Additionalsubgroup analysis was based on the Mayo score, extensive colitis, concomitant medications, high sensitivity C-reactive protein (hs-CRP) level, andpatient weight at baseline. The safety profile was assessed in all enrolled patients.Results: At week 8, 24% of patients receiving ADA were in clinical remission, compared with 28% on IFX (p>0.05). Clinical response was achievedin 48% of patients receiving ADA and 52% of patients on IFX (p>0.05). Mucosal healing was achieved in 40% of patients receiving either ADA orIFX (p>0.05). For the subscores indicative of mild disease (≤1), the patients % of RBS and PGA was significantly higher within IFX group (p<0.05)while the patients % of SFS was significantly higher within ADA group (p<0.05). The proportion of patients achieving clinical remission based on thepartial Mayo score, in addition to IBDQ response index, was not differ significantly between the two groups from week 2 and throughout the study(p>0.05). The patients with higher Mayo score (≥10), higher hs-CRP (≥10 mg/L), and higher weight (≥70 kg) at baseline were associated with reducedremission rates. ADA and IFX treatment were generally well-tolerated and the overall safety profile matched.Conclusion: ADA and IFX were comparable in their effectiveness for inducing clinical remission and response in patients with moderate to severe UC.Both of the biologic agents were well tolerated with an approach safety profile.Keywords: Ulcerative colitis, Adalimumab, Infliximab, Clinical remission, Safety profile.

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 &gt;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&lt;0.001) of patients. Mucosal healing at week 12 occurred in 3.4%, 10% and 34.5% (P&lt;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 The aim of this study to assess the efficacy and safety of adalimumab (ADA), a monoclonal antibody against tumour necrosis factor α (TNF-α), and to explore predictors of response in Korean patients with ulcerative colitis (UC). Methods We conducted a prospective observational multicenter study over 56 weeks in adult patients with moderately to severely active UC. Clinical response and remission were assessed by Mayo score. Mucosal healing was defined as Mayo subscore 0 or 1. Faecal calprotectin (FC) were assessed at baseline, week 8 and 56. Adalimumab drug levels were checked at week 8 and at loss of response. Missing or incomplete data were handled using the nonresponder imputation method. Results A total of 146 patients were enrolled and included in the analysis. Clinical response rates were 52.1% (76/146) and 37.7% (55/146) at week 8 and 56, respectively. Clinical remission was achieved in 24.0% (35/146) and 21.9% (32/146) of patients at week 8 and 56. Steroid-free remission rates were 21.2% (31/146) at week 56. Mucosal healing rates were 39.0% (57/146) and 30.1% (44/146) at week 8 and 56. Prior use of anti-TNF-α did not affect the clinical and endoscopic responses. Treatment persistence was achieved in 57.5% (84/146) of patients at week 56. Adalimumab drug level was significantly higher in patients with clinical response (10.8 vs. 8.0, p = 0.004), clinical remission (11.7 vs. 8.8, p = 0.007) and mucosal healing (11.0 vs. 8.5, p = 0.010) at week 8. Adalimumab dose was escalated to 40 mg weekly in 25 (17.1%) patients, and clinical response and remission were achieved in 40% and 20% of patients at week 56, respectively. Mean faecal calprotectin levels were significantly more decreased in clinical responders compared with non-responders at week 8 (336.3 mg/kg vs. 628.8 mg/kg, p &lt; 0.001). The Fecal calprotectin levels are well correlated with endoscopic severity, and the best cut-off value to predict mucosal healing was 274 mg/kg. The lower endoscopic severity, higher body mass index and higher serum albumin level at baseline were associated with a clinical response at week 8. The lower Mayo score, lower C-reactive protein level, clinical response (74.5% vs. 38.5%, p &lt; 0.001) and mucosal healing (52.7% vs. 30.8%, p = 0.008) at week 8 were associated with clinical response at week 56. Serious adverse drug reactions were identified in 2.7% (4/146) of patients including 1 case of pulmonary tuberculosis. Conclusion Adalimumab is safe and effective for induction and maintenance in Korean patients with UC, regardless of prior anti-TNF therapy. Adalimumab drug level is associated with the efficacy of induction therapy. A better response to induction therapy can predict a better long-term response.

Background and Aims: Several studies have found Golimumab (GOL) effective and safe in the short-term treatment of ulcerative colitis (UC), but few long-term data are currently available from real world. Our aim was to assess the long-term real-life efficacy and safety of GOL in managing UC outpatients in Italy. Methods: A retrospective multicenter study assessing consecutive UC outpatients treated with GOL for at least 3-month of follow-up was made. Primary endpoints were the induction and maintenance of remission in UC, defined as Mayo score ≤2. Several secondary endpoints, including clinical response, colectomy rate, steroid free remission and mucosal healing, were also assessed during the follow-up. Results: One hundred and seventy-eight patients were enrolled and followed up for a median (IQR) time of 9 (3-18) months (mean time follow-up: 33.1±13 months). Clinical remission was achieved in 57 (32.1%) patients: these patients continued with GOL, but only 6 patients (3.4%) were still under clinical remission with GOL at the 42nd month of follow-up. Clinical response occurred in 64 (36.4%) patients; colectomy was performed in 8 (7.8%) patients, all of them having primary failure. Steroid-free remission occurred in 23 (12.9%) patients, and mucosal healing was achieved in 29/89 (32.6%) patients. Adverse events occurred in 14 (7.9%) patients. Conclusions: Golimumab does not seem able to maintain long-term remission in UC in real life. The safety profile was good.

Abstract Introduction Ontamalimab is a fully human immunoglobulin G2 monoclonal antibody against mucosal addressin cell adhesion molecule-1 in development for the induction and maintenance of clinical remission in patients with ulcerative colitis (UC). This study aimed to assess the long-term pharmacokinetics (PK) of ontamalimab in patients with UC, and the effects of concomitant medications on PK parameters. Methods A 12-week induction study (TURANDOT; NCT01620255) was performed to assess the PK, efficacy and safety of ontamalimab (7.5, 22.5, 75 and 225 mg subcutaneous [s.c.] every four weeks [Q4W]) in patients with UC. Individuals who completed the induction study were eligible for enrollment in an open-label extension (OLE) study (TURANDOT II; NCT01771809) to assess the long-term PK, efficacy and safety of ontamalimab (75 or 225 mg s.c. Q4W up to week 72). Population PK analyses were performed using nonlinear mixed-effects modelling. Exposure-response analyses were performed to assess the relationships between minimum concentration (Cmin,ss) of ontamalimab and clinical response, clinical remission and mucosal healing. The effect of concomitant treatments (used for ≥20% of treatment duration) on PK parameters was also evaluated. Results The PK population included 130 (39.8%) women and 197 (60.2%) men, of median age of 40 years. A 1-compartment model with linear elimination adequately described the PK of ontamalimab. Population estimates of apparent clearance (CL/F) and volume of distribution (V/F) were 0.00917 L/h (0.22 L/day) and 7.44 L, respectively. Albumin had a significant effect on the variability of CL/F. Individuals with albumin levels of 30 g/L and 47 g/L are expected to have CL/F values 44% higher and 23% lower, respectively, than a typical patient with an albumin level of 39 g/L. Anti-inflammatory agents affected CL/F, such that CL/F is expected to be 14% higher in patients receiving than not receiving these agents. Other medications including immunosuppressants, steroids and treatments for peptic ulcers and gastroesophageal reflux disease had no effect on CL/F. Weight was the only covariate that significantly affected V/F. The half-life of ontamalimab was 23.4 days. Concentrations of ontamalimab over 72 weeks in the OLE study were consistent with those observed in the 12-week induction study. Ontamalimab Cmin,ss was related to efficacy, such that at week 16 (week 28 in total including induction), patients with higher Cmin,ss values were more likely to have clinical response, clinical remission and mucosal healing than those with lower Cmin,ss. Conclusion The exposure to ontamalimab was sustained following prolonged treatment in patients with UC for up to 72 weeks. Higher ontamalimab exposure was associated with a higher probability of clinical response.

Introduction. Tofacitinib is the first member of a new class of targeted synthetic anti-inflammatory drugs for the treatment of ulcerative colitis (UC). The article presents a three-year Russian experience of tofacitinib use for the treatment of moderate and severe UC.Aim of the study. To evaluate the efficacy and safety of tofacitinib therapy in real clinical practice in moderate to severe UC patients during three years of follow-up.  Methods. The study included 56 patients with UC who had moderate (60.7%) and severe (35.8%) states of disease, the total lesion was diagnosed in 67.8%, and extraintestinal manifestations in 57.1% of patients. Early achievement of clinical response, clinical and endoscopic, corticosteroid-free remission, and safety were evaluated.Results. Early response to tofacitinib therapy was obtained in 47 (83.9%) patients. Clinical remission was achieved in 36 (64.3%) at week 8 of therapy and clinical response was achieved in 13 (23.2%) patients. The majority of patients who achieved clinical remission at weeks 8 and 12 achieved healing of colon mucosa at week 24. Clinical and endoscopic remission rates after 24 weeks – 44 (78.6%) patients, clinical response in 7 (12.5%) patients, 5 (8.9%) did not respond to TFCB therapy. Corticosteroidfree remission was 77.6%. After 2 years of tofacitinib therapy, remission of UC was maintained in 46 (82.1%). After 36 months, remission of UC was maintained in 45 (80.3%) of the 56 patients who had been started on tofacitinib therapy. The cumulative effect of survival in the treatment of tofacitinib in UC was 87.5% after 6 months and persisted for one year, 82.1% after 2 years, and 80.3% after 3 years.Conclusions. The administration of tofacitinib in UC is effective in achieving rapid clinical response, clinical remission, and mucosal healing in patients who do not respond well to biological therapy.

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 &lt; 0.01) and 2.3 ± 1.9 at week 8 (P&lt;0.01). The average total cholesterol increased from 180.8 ± 36.0 mg/dl at entry to 206.8±39.3 mg/dl (p &lt; 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.

Introduction. Ulcerative colitis (UC) is one of the severe therapeutic diseases. High doses of oral granular mesalazine are required to maintain clinical and endoscopic remission of UC, which may be sufficient and supposedly more acceptable for patients, as some studies showed that adherence to topical therapy is significantly lower than to oral 5-ASA drugs.Objective of the study. To evaluate the efficacy of therapy of patients with moderate left-sided ulcerative colitis (UC) and pancolitis receiving prolonged-release ethylcellulose-coated mesalazine.Materials and methods. The evaluation of the outcomes of treatment of UC patients who received prolonged-release mesalazine was carried out. We examined 87 patients with UC who received granular ethylcellulose-coated mesalazine, of those 38 (43.7%) men and 49 (56.3%) women. The average age of the enrolled patients was 38.3 ± 12.6 years.Results and discussion. After 2 weeks from the beginning of therapy with prolonged-release mesalazine, the majority of patients – 71 (81.6%) responded to the therapy. After 12 weeks, 71 (81.6%) of 87 UC patients, who responded to therapy with prolongedrelease mesalazine, remained in clinical remission. On average, the Mayo score in the group decreased from 7.6 ± 0.99 to 2.6 ± 0.25 points. There was a significant decrease in CRP, ESR, leukocytosis, and fecal calprotectin. After 26 weeks, Mayo score in the group of patients remained on average at the level of 2.2–2.3 points. The number of UC patients with colon mucosal healing was 32 (36.8%) patients. A year after the start of therapy with prolonged-release mesalazine, 69 (79.3%) UC patients who responded to therapy had a clinical remission, of those 32 (36.8%) patients had a clinical and endoscopic remission. During the year of observation, no case of surgical intervention or re-hospitalization due to exacerbation of the disease was recorded in patients with UC who achieved remission.Conclusions. Treatment of moderate active UC should begin with oral mesalazine ≥ 3 g per day in combination with topical mesalazine. The prolonged-release mesalazines are the most preferred

Abstract Background Pediatric ulcerative colitis (UC) is characterized by low sustained remission rates and frequent extension of disease even if clinical remission is obtained with therapy. Moderate to severe endoscopic activity is a risk factor for relapse while evidence regarding early mucosal healing or persistence of inflammation after remission in children is not available. Our aim was to evaluate if persistence of significant inflammation is common and could explain the high relapse rate in pediatric UC. Methods Pediatric UC patients with clinical remission, defined as pediatric UC activity index (PUCAI) scores &lt; 10, were prospectively assessed for mucosal healing by endoscopy 3–5 months after remission was documented. Mayo score was assessed for each segment by a blinded adult gastroenterologist using central reading. Symptomatic patients prior to sigmoidoscopy were excluded Sustained remission was assessed retrospectively at 18 months follow-up. Results Forty-six children were enrolled, 28 children in continuous clinical remission at time of sigmoidoscopy were included in the final analysis. Mayo 0 was present in 12/28 (42.86%), Mayo 1 in 2/28 (7.1%) and Mayo 2–3 in 14/28 (50.0%) endoscopies. Among 23/28 patients with follow-up through 18 months, remission was sustained in 2/11 (18.18%) of patients with Mayo 2 and 3 versus 6/12 (50.0%) with Mayo score 0–1. Conclusion Over 50% of children assessed for mucosal healing 3–5 months after clinical remission is obtained have residual disease activity, primarily moderate to severe inflammation which was associated with lower sustained remission. Early sigmoidoscopy after clinical remission for assessment of mucosal disease should be considered in pediatric UC.

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 &gt;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&lt;0.001; Figure 1). For all ranked secondary endpoints, UPA was superior to PBO (P&lt;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 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
