Abstract Background The development program (UNIFI) has shown promising results of ustekinumab in ulcerative colitis (UC) treatment that should be confirmed in clinical practice. Aims Primary: to evaluate the durability of ustekinumab treatment in UC patients in clinical practice. Secondary: to assess the short-term response (at week 16) and the long-term effectiveness (at maximum follow-up) and to assess the safety of ustekinumab in clinical practice. Methods Patients included in the prospectively maintained ENEIDA registry who received at least one intravenous dose of ustekinumab due to active UC [Partial Mayo Score (PMS) >2] were included. Clinical activity and effectiveness were defined based on PMS. Results 95 patients were included (table 1). At week 16, 53% of patients had clinical response (including 35% of patients in remission) (figure 1). In the multivariate analysis, elevated serum C-reactive protein was the only variable significantly associated with clinical remission. Long-term remission is represented in figure 2. 36% of patients discontinued the treatment with ustekinumab during a median follow-up of 31 weeks. The probability of maintaining ustekinumab treatment was 87% at week 16, 63% at week 56, and 59% at week 72 (figure 3); primary failure was the main reason for ustekinumab discontinuation. No variable was associated with risk of discontinuation. Three patients reported adverse events; one of them had a fatal severe SARS-CoV-2 infection. Conclusion Ustekinumab is effective both in the short and the long-term in real-life, even in a highly refractory cohort. Higher inflammatory burden at baseline correlated with lower probability of achieving remission. Safety was consistent with the known profile of ustekinumab.

Abstract Background Ustekinumab has shown promising results in ulcerative colitis (UC) in the development program (UNIFI) that should be confirmed in clinical practice. Our aim was to evaluate the effectiveness and safety of ustekinumab in UC in real life. Methods Patients included in the prospectively maintained ENEIDA registry that received at least 1 dose of ustekinumab intravenously due to active UC were included. Clinical activity and effectiveness were defined based on Partial Mayo Score (PMS). The short-term response was assessed at week 8 and 16. The last-observation-carried-forward method was used in patients that stopped ustekinumab treatment before week 8 or 16. Variables associated with short-term remission were identified by logistic regression analysis. Data quality was assessed by remote monitoring. Results Forty-seven patients were included (Table 1); all of them had been previously exposed to biologic agents (70% to >2): 100% to anti-TNF and 83% to vedolizumab. A total of 26% had been exposed to tofacitinib. Seventeen patients (36%) had response at week 8 [3 of them (6%) had remission]; 16 patients (34%) had response at week 16 [5 of them (11%) had remission] (Figure 1). There was a statistically significant decrease in C-reactive protein (CRP) concentration during the induction only in patients with a response at week 16 (Figure 2). The proportion of patients with CRP elevated at baseline and at week 8 was higher among non-responders at week 16 (Table 2). In the multivariate analysis, higher PMS at week 8 [odds ratio (OR) = 0.5; 95% confidence interval (CI) = 0.3–0.9)] and CRP over the upper normal limit at week 8 (OR = 0.1; 95% CI = 0.01–0.8) were associated with lower probability of response at week 16; steroids during induction increased the probability of response at week 16 (OR = 8; 95% CI = 1–71). Of patients without response at week 8, only 7% achieved response at week 16. Seventeen out of 31 patients continued ustekinumab beyond week 16, despite being non-responders. Of these 17 patients, 4 reached remission after the third dose, 1 after the fifth and 1 after the seventh one. There were 2 infections, one of them with fatal consequences (in a patient under steroids and tacrolimus due to renal transplant). Conclusion Ustekinumab shows benefit in some UC patients in real practice, even in a very refractory cohort in which the drug was prescribed as last resort. Patient status at week 8 seems to be a good predictor of response after the induction. Safety was consistent with the known profile of ustekinumab.

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 Aim To evaluate the effectiveness and safety of tofacitinib in ulcerative colitis [UC] in real life. Methods Patients from the prospectively maintained ENEIDA registry and treated with tofacitinib due to active UC were included. Clinical activity and effectiveness were defined based on Partial Mayo Score [PMS]. Short-term response/remission was assessed at Weeks 4, 8, and 16. Results A total of 113 patients were included. They were exposed to tofacitinib for a median time of 44 weeks. Response and remission at Week 8 were 60% and 31%, respectively. In multivariate analysis, higher PMS at Week 4 (odds ratio [OR] = 0].2; 95% confidence interval [CI] = 0].1–0.4) was the only variable associated with lower likelihood of achieving remission at Week 8. Higher PMS at Week 4 [OR = 0.5; 95% CI = 0.3–0.7] and higher PMS at Week 8 [OR = 0.2; 95% CI = 0.1–0.5] were associated with lower probability of achieving remission at Week 16. A total of 45 patients [40%] discontinued tofacitinib over time. Higher PMS at Week 8 was the only factor associated with higher tofacitinib discontinuation [hazard ratio = 1.5; 95% CI = 1.3–1.6]. A total of 34 patients had remission at Week 8; of these, 65% had relapsed 52 weeks after achieving remission; the dose was increased to 10 mg/12 h in nine patients, and five of them reached remission again. Seventeen patients had adverse events. Conclusions Tofacitinib is effective and safe in UC patients in real practice, even in a highly refractory cohort. A relevant proportion of patients discontinue the drug over time, mainly due to primary failure.

Background and Aims: Treatment with intravenous corticosteroids (IVCS) is a mainstay in the management of acute severe ulcerative colitis (UC). Although most patients respond to IVCS, little is known about the long-term outcomes. In this study, we assessed the long-term outcomes of IVCS in a real-life cohort. Methods: Disease activity, clinical relapse (partial Mayo score >4), the need for steroids or other maintenance therapies and the rates of colectomy and re-hospitalization were evaluated in consecutive patients admitted to the Tor Vergata University hospital between 2010 and 2020 for acute severe UC who responded to IVCS. Results: Eighty-eight patients were followed up with for a median period of 46 (range 6–133) months. Of these, 56 (64%) patients were treated with 5-aminosalycilic acid and 32 (36%) with immunomodulators or biologics after discharge. A total of 60 out of 88 patients (68%) relapsed, 28 (32%) were re-hospitalized, and 15 (17%) underwent a colectomy with no difference between the two maintenance therapy groups. The multivariate analysis showed that patients in clinical remission 6 months after discharge had a lower risk of relapse during the follow-up. Conclusions: Nearly two-thirds of patients with acute UC responding to IVCS experienced relapse after a median follow-up of 4 years, and this was not influenced by the maintenance therapy.

Abstract Background Mucosal healing is an important goal in the treatment of ulcerative colitis (UC). The newly published PICaSSO score characterises subtle mucosal and vascular changes and defines mucosal healing. We aimed to validate in real-life the PICaSSO score and assess its ability to predict relapse. Methods Patients with UC were prospectively recruited from 11 international centres. Participating endoscopists experienced in IBD received training on PICaSSO before starting the study. The rectum and sigmoid were examined using iScan 1,2 and 3 (Pentax, Japan) and inflammatory activity was assessed using UCEIS and PICaSSO. Biopsies were taken for the histological assessment using Robarts Histological Index (RHI) and Nancy. Follow-up was obtained at 12 months. Results A total of 278 patients were recruited (Table 1). The diagnostic performance in predicting histologic healing is shown in Table 2. When using PICaSSO score of ≤3 for mucosal and vascular architecture the AUROC to predict healing by RHI is 0.79 (95% CI 0.74–0.85) and 0.73 (95% CI 0.68–0.80) respectively and when using the Nancy score the AUROC is 0.78 (95% CI 0.72–0.84) and 0.77 (0.71–0.84). A total PICaSSO score of ≤8 and UCEIS score of ≤1 predicts remission at 12 months with an AUROC of 0.73 (0.65–0.80) and 0.71 (0.64–0.79). A Kaplan–Meier curve shows a favourable survival probability without relapse with a PICASSO score of ≤8 (Figure 1). Conclusion This real-life validation study shows the PICaSSO score can predict accurately histological healing and long-term remission and can be a useful tool in the management of UC.

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 Golimumab has demonstrated its long-term efficacy and safety in ulcerative colitis in clinical trials, but no data of long-term persistence has been published from real world. To estimate long-term persistence of golimumab, as well as factors associated with longer persistence, in patients with ulcerative colitis in real life. Observational multicentre study including adult patients with ulcerative colitis treated with golimumab and with at least twelve months of follow-up. We included 190 patients, 105 (55.26%) naive to anti-TNF, with mean disease duration of 9.32 ± 8.09 years. Probability of persistence was 63%, 46%, 39% and 27% at 1, 2, 3 and 4 years, respectively. Persistence was lower in patients with primary failure to previous anti-TNF. Eighty-two (43.16%) patients needed dose intensification during follow-up, with a mean time until intensification of 8.03 ± 8.64 months. Dose intensification and lower disease duration predicted higher persistence with golimumab (p = 0.037 and p = 0.008, respectively). During a follow-up of 17.25 ± 15.83 months, 32 (16.5%) patients needed hospitalisation and 11 (6%) underwent colectomy. No unexpected adverse events were reported. Golimumab has demonstrated good persistence and safety profile for long treatment in ulcerative colitis patients.

Abstract Background No real-life study aiming at comparing at the same time the effectiveness of vedolizumab (VDZ), adalimumab (ADA), and golimumab (GOL) in Ulcerative colitis (UC) is currently available. Methods Data of consecutive patients with UC treated with VDZ, ADA, and GOL from June 2015 to December 2018 were extracted from the cohort of the Sicilian Network for Inflammatory Bowel Disease (SN-IBD). A three-arms propensity score-adjusted analysis was performed to reduce bias caused by imbalanced covariates at baseline, including the proportion of TNF-α inhibitor naïve and non-naïve patients, using the Inverse Probability of Treatment Weighting (IPTW) method. The effectiveness was evaluated at 8 weeks, 52 weeks, and as treatment persistence at the end of follow-up. The clinical endpoints were steroid-free clinical remission (partial Mayo score <2 without steroid use) and clinical response (reduction of the partial Mayo score ≥2 points with a concomitant decrease of steroid dosage compared with baseline). The sum of the two outcomes was defined as a clinical benefit. The achievement of mucosal healing (endoscopic Mayo score 0–1) was assessed after at least 6 months of biological treatment. Results A total of 463 treatments (VDZ: n = 187; ADA: n = 168; GOL: n = 108) were included, with a median follow-up of 47.6 weeks (IQR 20.0–85.9). At 8 weeks, a clinical benefit was achieved in 70.6% patients treated with VDZ, in 68.5% patients treated with ADA, and in 67.6% patients treated with GOL (p = n.s. for all comparisons). After 52 weeks, VDZ showed better rates of clinical benefit compared with both ADA (71.6% vs. 47.5; OR: 2.79, 95% CI 1.63–4.79, p < 0.001) and GOL (71.6% vs. 40.2%; OR: 3.77, 95% CI 2.08–6.80, p < 0.001), while the difference between ADA and GOL was not significant. Cox survival analysis demonstrated that patients treated with VDZ had a reduced probability of treatment discontinuation compared with those treated with ADA (HR: 0.42, 95% CI 0.28–0.64, p < 0.001) and GOL (HR: 0.30, 95% CI 0.19–0.46, p < 0.001), while patients treated with ADA had a reduced risk of treatment discontinuation compared with those treated with GOL (HR: 0.71, 95% CI 0.50–1.00, p = 0.048). Post-treatment mucosal healing rates showed a numerical but non-significant difference in favour of VDZ (48.1%) compared with ADA and GOL (38.0% and 34.6%, respectively). Conclusion In the first study comparing at the same time the clinical effectiveness of VDZ, ADA, and GOL in UC patients via propensity score-adjusted analysis, VDZ was superior to both subcutaneous agents at 52 weeks and as treatment persistence, while ADA showed a superior treatment persistence compared with GOL.

Abstract Background Studies have reported good efficacy outcomes for patients with inflammatory bowel disease (IBD) treated with biosimilars. There are limited long-term data. We assessed the long-term efficacy data and safety after switching from adalimumab to adalimumab biosimilars in patients with IBD. Methods A prospective single-centre observational study involving patients with Crohn’s disease or ulcerative colitis switched from adalimumab to adalimumab biosimilar and reviewed up to 12months. Efficacy and loss of response were measured using the Harvey–Bradshaw (HB) index and partial Mayo score for patients with Crohn’s disease and ulcerative colitis respectively. Blood tests including C-reactive protein, adalimumab drug levels and anti-drug antibodies were monitored. We have recorded side effects and possible serious adverse effects. The plan is to continue the study for 24 months. Results 109 patients with IBD have completed at least 6 months of treatment with adalimumab biosimilar, 12 of which have ulcerative colitis and 97 Crohn’s disease. Most of them (88%) continued on biosimilar after 6 months. Patients discontinued the therapy due to loss of response or development of antibodies in one case. Two patients were switched to a different biosimilar due to the presence of side effects which were however not serious. Of those who remained on the treatment, 74.5% were in clinical remission at 6 months and 71.4% at 9 months. HB index, partial Mayo score, C-reactive protein and adalimumab drug levels did not show significant changes. We have not reported any serious adverse events. We hope than by February, at least 60% of these patients will have been on Adalimumab for 12 months and further amended date would be added. Conclusion Most of the patients switching from original adalimumab were maintained on biosimilar at 6 and 12months of follow-up with similar efficacy and safety as the original drug.

Abstract Background Our aim was to evaluate the effectiveness and safety of tofacitinib in ulcerative colitis (UC) in real life. Methods Patients from the prospectively maintained ENEIDA registry treated with tofacitinib due to active UC were included. Clinical activity and effectiveness were defined based on Partial Mayo Score (PMS). The short-term response was assessed at week 4, 8 and 16. The last-observation-carried-forward method was used in patients that stopped tofacitinib before the time-points for clinical assessment. Variables associated with short-term remission at week 8 were identified by logistic regression analysis. The cumulative retention rate and the cumulative incidence of relapse over time were assessed by survival curves. Cox-regression analysis was performed to identify predictive factors of tofacitinib discontinuation or relapse over time. Data quality was assessed by remote monitoring. Results 113 patients were included (Table 1 and Figure 1) and exposed to tofacitinib a median of 44 (interquartile range = 30–66) weeks. Response and remission at week 8 were 60% and 31%, respectively (Figure 2). In multivariate analysis, higher PMS at week 4 [odds ratio (OR)=0.2; 95% confidence interval (CI) = 0.1–0.4] was the only variable associated with the likeliness of achieving remission at week 8. Higher PMS at week 4 (OR = 0.5; 95% CI = 0.3–0.7) and higher PMS at week 8 (OR = 0.2; 95% CI = 0.1–0.5) were associated with lower probability of achieving remission at week 16. Twenty per cent of those without remission at week 4, and 12% of those without remission at week 8, achieved remission at week 16. A total of 45 patients (40%) discontinued tofacitinib over time (Figure 3); the discontinuation rate was 34% and 46% at 24 and 52 weeks, respectively. PMS at week 8 was the only factor associated with tofacitinib discontinuation [Hazard ratio (HR) = 1.5; 95% CI = 1.3–1.6)]. A total of 33 patients had remission at week 8; from them, 65% relapsed 52 weeks after achieving remission; 9 patients increased the dose to 10 mg /12 h and 5 reached remission again. No factors associated with relapse over time were identified. Eighteen patients had adverse events (4 hypercholesterolaemia, 2 herpes zoster, 3 infections, 2 dyspnoea, 1 neoplasia, 1 lymphopenia, 1 headache, 1 hypertriglyceridaemia and 4 others). No thromboembolic events were reported. Conclusion Tofacitinib is relatively effective in UC patients in real practice even in a highly refractory cohort. Only 10% of the patients without remission at week 8 reached remission at week 16. A relevant proportion of patients discontinue the drug over time, mainly due to primary failure. Over 60% of patients that achieve remission, relapse over time. Safety was consistent with the known profile of tofacitinib
