Abstract Background Real-life long-term evidence on ustekinumab treatment in patients with Crohn’s disease (CD) is limited. We performed a retrospective non-interventional nation-wide chart review study of dosing and long-term clinical outcomes in Finnish CD patients treated with ustekinumab (FINUSTE2, EUPAS30920). Methods FINUSTE2 was carried out in 17 Finnish centres. Eligible patients were adults with CD, receiving an intravenous (IV) first dose of ustekinumab during 2017 or 2018. Data on disease activity, dosage, and concomitant medications were collected at baseline, 16 weeks, and 1 year from treatment initiation. All measurements on ustekinumab trough concentrations (TC) were recorded. Results The study included 155 patients (48% female) with a mean age of 44 and disease duration of 14 years. The disease was stricturing or penetrating in 69% of patients, 59% had prior CD-related surgeries, and 96% had a treatment history of at least one biologic agent. After one IV dose and one to two subcutaneous (SC) doses at 8 to 16 weeks, 140 patients (93%) continued to maintenance treatment with SC ustekinumab, of which nearly three-quarters with a dosage interval of 8 weeks (Figure 1). Of 93 patients with a follow-up of at least 1 year, 77 were still on ustekinumab. During follow-up, 55 patients (39%) had their ustekinumab dose adjusted, mostly (n = 44, 31.4%) as a shortening of the dosage interval. Forty-nine patients had in total 65 ustekinumab TC measurements performed, with a mean of 2.2 µg/ml at 16 weeks (n = 23) and 2.7 µg/ml at 1 year (n = 25). In 67% of cases, the reason for measuring TC was lack of or insufficient response. No anti-drug antibodies appeared at any time point. The proportion of patients on ustekinumab monotherapy increased significantly, from 34% (n = 52) at baseline to 54% (n = 79/146; p < 0.001) at 16 weeks and 64% (n = 49/77; p < 0.01) at 1 year. Correspondingly, corticosteroid use decreased significantly, and a trend towards reduced use of immunomodulators was observed (Figure 2). Conclusion In this nationwide real-life study, treatment with ustekinumab in patients with longstanding and complicated CD was persistent and allowed for significant corticosteroid tapering. A vast majority started the maintenance treatment with an 8-week dosage interval and nearly one-third of all patients required a dose increase, suggesting a highly refractory disease phenotype. The lack of detected antidrug antibodies during follow-up indicates low immunogenicity for ustekinumab.

Abstract Background Adalimumab (ADA) is one of the most preferred anti-TNF agents because of its ease of use in real life. We aimed to evaluate the efficacy of ADA in the long-term period of inflammatory bowel disease (IBD) patients. Methods Patients treated with adalimumab (ADA) as the first- and second-line biological treatment for mild to moderate active IBD between January 2009 and March 2019 were included. The clinical and endoscopic response rate of ADA were evaluated, retrospectively. Remission was defined in ulcerative colitis patients (UC), if stool frequency ≤ 3/day with no bleeding and no mucosal lesions at the colonoscopy. Remission was defined in Crohn’s disease patients (CD) if CDAI < 150 and mucosal healing at the colonoscopy. Results Fifty-eight patients (81% Crohn’s disease, 58.6% biologic naive) were included in this study. Mean age was 41.4 ± 12.3 years old (19–67 years) and 46.6% of them were female. Median follow-up time was 57 months in UC and 65 months in Crohn’s disease (CD). Infliximab experience rate before ADA in UC and CD was 36.4%, 42.6%, respectively. CD’s related surgery rate was 43.5%; surgery rate 87.5% before ADA therapy and 12.5% after ADA treatment. Clinical and endoscopic remission rates were 81.8% / 63.6% and 89.4%/ 63.4 in UC and CD, respectively at the end of follow-up period. Loss of response rate was 20% in UC and 28.3% in CD (table). Mean months for loss of response were 42 ± 25.4 months and 29.7 ± 12 months in UC and CD, respectively. Clinical remission was obtained by dose escalation in 66% of CD patients who had response loss. Loss of response rate was not significantly different between IFX naive and IFX experienced patients (p > 0.05). There was no significant adverse event during the follow-up period. Conclusion In real life, the efficacy of ADA treatment is high in mild-to-moderate active IBD. Endoscopic remission was also acceptable for this group of patients.

Abstract Background Adalimumab is a safe and effective drug in treatment of Crohn’s Disease (CD). Current literature is not definitive regarding an exact timing for treatment withdrawal and disease relapses after drug discontinuation. Methods We conducted a single-centre, retrospective, observational cohort study involving patients affected by Crohn’s Disease (CD) treated with adalimumab. Of 575 patients treated with adalimumab for CD, 149 patients suspended treatment for stable deep remission (clinical steroid-free, biochemical, endoscopic remission defined as mucosal healing). Of these, 126 have a minimum follow up of 4 years, the other 23 where lost or finished the follow-up. Patients were assessed clinically, laboratoristically and endoscopically for 4 years. Relapse was defined as clinical (HBI > 4) and biochemical (PCR > 0.5 mg/dL). Results Of the 126 patients with 4 years follow-up, 64 (51%) maintained deep remission during the 4 year follow-up period. Of these, 38 (59%) were on exit-therapy with thiopurines. Twenty-seven patients (18%) had relapsed by year 1, 24 (18%) by year 2, 8 (6%) by year 3, and 1 (0.8%) by year 4. Relapses needed surgical therapy in 9 (15%) cases, whereas 36 (60%) were retreated with adalimumab and 4 (7%) with another biologic agent. The remaining 11 patients (18%) were treated only with a course of steroids. Conclusion Patients who suspend treatment with adalimumab for stable deep remission maintain remission in the long term in approximately half of cases. The majority of relapses occur in the first 24 months after discontinuation.

Abstract Background Real-life long-term evidence on ustekinumab treatment response in patients with Crohn’s disease (CD) is scarce. We performed a retrospective non-interventional nationwide chart review study of dosing and long-term clinical outcomes in Finnish CD patients treated with ustekinumab (FINUSTE2, EUPAS30920). Methods FINUSTE2 involved 17 Finnish centres. Eligible patients were adults with CD, receiving an intravenous first dose of ustekinumab during 2017 or 2018. Disease activity data, such as C-reactive protein (CRP), faecal calprotectin (fCal), and the Simple Endoscopic Score for Crohn’s disease (SES-CD) were collected at baseline, 16 weeks, and one year from treatment initiation. A local gastroenterologist at each centre collected the data from health records in an electronic standardised health questionnaire. Results One hundred and fofty-five patients (48% female) with a mean age of 44 and disease duration of 14 years initiated ustekinumab treatment for CD. Table 1 summarises patient characteristics at baseline. After induction consisting of one intravenous dose and one to two subcutaneous doses at 8 to 16 weeks, 140 patients (93%) continued to maintenance treatment with subcutaneous ustekinumab. Of 93 patients with a follow-up of at least one year, 77 were still on ustekinumab. During ustekinumab treatment, SES-CD (10 at baseline, 3 at 1 year, medians, p = 0.033) and CRP (7 mg/l at baseline, 5 mg/l at 1 year, medians, p < 0.001) and fCal (776 μg/g at baseline, 305 μg/g at 1 year, medians, p < 0.001) decreased significantly in those patients with data available. Figure 1 describes changes in fCal levels over time. Conclusion In this nationwide real-life long-term follow-up study, covering all major centres in Finland, ustekinumab treatment of patients with highly refractory and long-standing CD effectively reduced inflammatory activity, assessed by endoscopy, CRP, and fCal.

Abstract Background Long-term effectiveness of vedolizumab (VDZ) in real-life clinical practice is unknown. We aimed to evaluate clinical efficacy and treatment persistence of VDZ in a real-world cohort of patients with Crohn’s disease (CD). Methods CD patients from a single tertiary IBD referral centre receiving VDZ treatment outside clinical trials between September 2016 and August 2019 were included. Data were collected prospectively at baseline, weeks 22, 54, and 108. Disease activity was assessed using the Harvey Bradshaw index (HBI). The primary endpoint was steroid-free clinical remission, defined as HBI of 4 or lower without the need of corticosteroids. Secondary endpoints were treatment persistence and durability of VDZ response. Results Up to August 2019 114 patients had received at least one VDZ infusion, 79% had prior anti-TNFα drug exposure. Of the 90 patients who reached 54 weeks of follow-up, 68 patients (75,5%) were still under VDZ therapy. 38 of them (55,9%) were in steroid-free clinical remission. We compared the initial response to VDZ at week 22 and at week 54. Among the 29 patients in steroid-free clinical remission at week 22, 25 (86.2%) were still in steroid-free clinical remission at week 54. Three out of 29 patients discontinued VDZ therapy before week 54, for insufficient response and adverse events in two cases and for pregnancy in one. Of the 34 patients who reached 108 weeks of follow-up, 17 (50%) were still under VDZ therapy. 11 of them (64.7%) were in steroid-free clinical remission. We compared the initial response to VDZ at week 22 and at week 108. Among the 11 patients in steroid-free clinical remission at week 22, 6 (54.5%) were still in steroid-free clinical remission at week 108. Two out of 11 patients discontinued VDZ therapy before week 108 for worsening of perianal disease. Conclusion After 1 year, 75.5% of patients were still on treatment, of whom more than 55% achieved remission. 86% of patients maintained a response after the first year of treatment. After 2 years the rate of patients who presented with steroid-free clinical remission and who maintained response tended to decrease, consistent with previously published data. However, half of the patients persisted with VDZ treatment. These data support the long-term effectiveness and favourable safety profile of VDZ.

Abstract Background ReFLECT study was carried out to investigate real-life use of CT-P13, the first monoclonal antibody biosimilar to infliximab (IFX) originator. Methods This multicentre, prospective, observational study was conducted in France to assess characteristics of patients (pts) receiving CT-P13, its effectiveness and safety in a real-life setting. Eligible were both pts who had been switched from IFX originator (IFXS) and IFX-naïve pts started on CT-P13 (IFXN). These interim descriptive statistical analyses are about pts with Crohn’s disease (CD) and ulcerative colitis (UC). Results Among the 1370 adult pts included between October 2016 and April 2019, data were analysed for 508 CD pts (48.6% males; mean age ± SD: 37.7±13.7; median [Q1;Q3] disease duration: 6.2 [1.9;13.7] years; 323 IFXN/145 IFXS) and 213 UC pts (54%; 42.9±17.2; 5.4 [1.6;12.8]; 154 IFXN/46 IFXS). Previous biologics other than IFX were taken by 32.9% of CD and 39.0% of UC pts; 31% (CDS) and 23% (UCS) of pts were switched from IFX originator to CT-P13. At the time of the first administration of CT-P13, disease had been more active in IFXN vs IFXS pts: 52.9% vs 13.3% in CD with a median [Q1;Q3] Harvey Bradshaw Index (HBI) of 4 [1;8] vs 1 [0;2] and, 82.9% vs 33.3% in UC with a median Mayo Score of 7 [3;10] vs 2 [0;4]. In IFXS pts, disease activity remained stable after 2 years of treatment with median differences of HBI and Mayo score since first administration of 1 [0;2] and 0 [-4;1]. In IFXN pts, median differences of HBI and Mayo score since first administration were -2 [-7;1] and -7 [-8;-5]; CT-P13 brought disease activity down to levels below or comparable to those seen in IFXS pts. Reasons for CT-P13 withdrawing and safety data are reported in Tables 1 and 2. Conclusion Year 2 follow-up data indicate that CT-P13 effectively induced improvement in disease activity in IFXN pts with CD or UC and maintained stable activity in IFXS pts. This real-life study did not highlight any new safety concerns.

Abstract Background The efficacy of ustekinumab in patients with Crohn’s disease (CD) refractory to anti-TNF is worse than in anti-TNF naïve patients. Methods Retrospective study of patients with CD refractory or intolerant to TNF initiating ustekinumab between January 2013 and March 2020, with a minimum follow-up of 12 months, and without corticosteroid treatment. Our aim was evaluated clinical response (reduction of CDAI >100), clinical remission (CDAI <150) and biochemical remission (CDAI <100 and CRP <1 mg/L and faecal calprotectin <100 µg/g) in short and long term. Results A total of 49 patients with a medium follow-up of 28 months (IQR:13-37) were included. Patients baseline characteristics are reflected in Table 1. In 20% patients the induction was made subcutaneous (90 mg/week for 4 weeks). At week 52, clinical response, clinical remission and biochemical remission was 93%, 82% and 54% respectively (Figure 1). In the long term (3 years), 62% had clinical response, 52% remained in clinical remission, and 48% showed biochemical remission. 1/3 of patients needed intensification every year. Ustekinumab treatment discontinuation was observed in 13 patients (27%) mainly due to lack of response (6[12%]: primary, 7[14%]: secondary). No serious adverse effects have been reported. Conclusion About 50% of the patients are in clinical and biochemical remission at week 152 in a real-life cohort of anti-TNF-exposed CD patients. With a harder remission definition including biochemical parameters, our results in real life are similar to pivotal studies at week 152. Nevertheless, at week 52 our remission rates were higher.

Abstract Background Ustekinumab (UST), a human anti-IL12/23p40 monoclonal antibody, was approved by FDA and EMA for the treatment of moderate to severe Crohn’s disease (CD). Whether UST is effective in inducing deep remission, including mucosal healing and transmural healing, in patients with CD in a real life setting is not completely clear. Methods The study was performed on 92 subjects (47 males; 45 females; mean age: 42 (17–78) from six medical centers in Campania, Italy, with confirmed diagnosis of moderate to severe Crohn’s disease and no neoplasia. In all patients diagnosis of CD had been reached to years earlier. Before inclusion, all patients had been exposed and had failed to respond to conventional and/or at least one biological therapy.The administration of UST was as follows: IV infusion at week 0 (3 vials of 130 mg each if body weight of 55–85 kg; 2 vials of130 mg each if body weight < 55 kg) and subsequent SC injections (90 mg) q8w thereafter. At enrollment, all subjects underwent colonoscopy and were divided into groups according to endoscopic evaluation: 5 (5.4%) patients had erosions; 24 (26.1%) inflammation; 63 (68.5%) ulcers. Based on the CDAI value, 52 (56.5%) patients had a CDAI of 180–220, 35 (38%) had a CDAI of 220–450, and 5 (5.4%) had a CDAI >450. All patients underwent endoscopic examination and bowel MRI or ultrasonography at baseline and at week 52 to evaluate mucosal and transmural healing. Clinical response was defined as a reduction of CDAI by at least 100 points; clinical remission when CDAI was lower than 150. Clinical response and remission were evaluated at baseline and on 5 different occasions throughout a 12 months follow-up. Incidence of treatment-related adverse events (TRAEs) was recorded during the study period. Results Seventeen patients interrupted therapy while 75 patients continued follow-up until the fifth visit. Clinical response at week 52 was achieved in 38 (50,5%) patients and clinical remission in 29 (39%). Twenty-six (34%) patients showed mucosal healing, 34 (45%) showed partial endoscopic response. Fifteen patients (20%) did not show any change during endoscopic evaluation at follow-up. All patients showing mucosal healing also showed transmural healing, as assessed by ultrasonography or MRI. No major TRAEs were observed during treatment. Conclusion In this multi-center, real life study, we show that UST was well tolerated and effective in inducing clinical response and clinical remission in patients with moderate to severe CD who had previously failed to respond to conventional or biologic therapy. UST showed limited efficacy in inducing deep remission (i.e. mucosal+transmural healing).
