Abstract Background Prospective, observational real world studies on the effectiveness and safety of ustekinumab (UST) in Crohn’s disease (CD) are required in addition to RCTs, usually confined to selected patients, which may not represent special treatment patterns and everyday clinical practice. The aim of the present 3-year RUN-CD study was to investigate the induction phase effectiveness of UST vs. other biologics (OB) in CD in terms of clinical and steroid-free remission at week 16. To the best of our knowledge, RUN-CD is currently the largest prospective real world evidence (RWE) study with UST in CD using propensity score adjustment. Methods Between 2017–2020, 901 CD-patients starting a new therapy with UST or OB, were enrolled in 44 IBD-experienced centers across Germany. After exclusion of missing outcomes, the final sample consisted of 657 patients. Clinical remission (HBI ≤ 4), and steroid-free remission (HBI ≤ 4 and no systemic use of steroids or budesonide during the last 8 weeks) were considered as outcomes at week 16. To reduce the effect of confounders, propensity score (PS) adjustment with inverse probability of treatment weighting (IPTW) was implemented. A weighted logistic regression was used, and the results were reported as odds ratio (OR) and 95% confidence interval (CI). Results 339 UST (naïve: 34) and 318 OB CD-patients were included (ADA: 50.3%, IFX: 37.4%, VDZ: 12.3%) (naïve: 203). PS removed systematic differences between both groups (30.8% smokers, 15.1% perianal disease, 36.2% surgical resection, 40.5% EIM). The effectiveness of UST for clinical and steroid-free remission was comparable to that of OB at week 16. Besides, in bio-naïve patients, clinical remission was numerically, though not significantly, higher in UST vs OB (Table 1). Similar results were observed in the bio-experienced UST vs. OB groups [remission: 59.3% vs 55.4%; OR: 1.17 (0.73–1.90)]. For both the remission rates were higher in the bio-naïve than in the bio-experienced groups (p<0.05 for both). Conclusion In this prospective RUN-CD study, with propensity score weighted groups, UST showed similar induction effectiveness in comparison with OB therapies. Remarkably higher remission rates were observed in this RWE study than in prior RCTs. An additional favorable safety profile supports consideration of UST as a first-line targeted therapy for CD.

Abstract Background Vedolizumab (VDZ) is an effective treatment for Crohn’s disease (CD); however, inadequate and loss of response is common. Pivotal VDZ trials evaluated alternative dosing intervals, demonstrating numeric but not statistical superiority in efficacy as compared to FDA-approved dosing. The safety and effectiveness of FDA-approved and modified-dosing schedules in a real-world population are unknown. We aimed to evaluate clinical and endoscopic effectiveness & safety of standard and modified maintenance VDZ dosing in a real world cohort. Methods We retrospectively reviewed CD patients (pts) treated with >3 months VDZ, assessing Harvey Bradshaw Index (HBI), Simple Endoscopic Score for Crohn’s disease (SESCD), Short Inflammatory Bowel Disease Questionnaire (SIBDQ), C-reactive protein (CRP), albumin and hematocrit prior to and following standard VDZ dosing, and prior to and following modified VDZ maintenance dosing. We measured duration on therapy and adverse events. Results We identified 226 eligible pts, mean age 41.5 years, 55.3% female, median disease duration 10 years, 88.9% with prior biologic exposure. Mean duration on VDZ was 28.3 months. Standard VDZ dosing: 61.5% of pts with active clinical disease and adequate follow up data achieved clinical response after 3–12 months; 41.0% had clinical remission. 51.9% of pts with active endoscopic disease and adequate follow up data achieved mucosal improvement; 42.3% had endoscopic remission; 26.0% had mucosal healing after 3–24 months. 50.0% of pts with elevated CRP and adequate follow up data normalized CRP after 3–12 months. Modified maintenance dosing: 72 non-remitters to standard VDZ dosing received modified VDZ maintenance dosing. 51.5% of pts with active clinical disease prior to starting dose modification and adequate follow up data achieved clinical response after 3–12 months of modified maintenance dosing; 42.4% had clinical remission. 22.2% of pts with SESCD ≥3 prior to starting dose modification achieved mucosal improvement after 3–24 months; 22.2% had mucosal healing. 26.7% of pts with SESCD ≥4 prior to starting modified dosing had endoscopic remission after 3–24 months. 50.0% of pts with elevated CRP and adequate follow up data normalized their CRP after 3–12 months. Safety: 82.7% of pts reported ≥1 adverse events, most commonly infection and worsening CD symptoms. Discussion Standard VDZ dosing resulted in clinical and endoscopic improvement in pts with moderate-severe CD, with prior exposure to multiple advanced therapies. For non-remitters to standard dosing, modified VDZ maintenance dosing improved clinical disease activity in ∼50% of pts and improved endoscopic disease activity in ∼20% of pts, suggesting that for pts who did not achieve remission with standard VDZ dosing, modified VDZ dosing may result in clinical and endoscopic improvement.

Abstract Background Ustekinumab is a monoclonal antibody that selectively targets p40, a shared subunit of the cytokines interleukin (IL)-12 and IL-23. It is registered for the treatment of Crohn’s disease (CD) and ulcerative colitis. We assessed the two-year efficacy and safety of ustekinumab in a real world, prospective cohort of CD patients. Methods CD patients who started ustekinumab in regular care were prospectively enrolled in the nationwide Initiative on Crohn and Colitis Registry. At week 0, 12, 24, 52 and 104, clinical remission (HBI ≤ 4 points), biochemical remission (fecal calprotectin (FC) ≤200 μg/g and/or CRP ≤5 mg/L), peri-anal fistula remission, extra-intestinal manifestations, ustekinumab dosage and safety outcomes were determined. Patients starting therapy less than two years ago were excluded for the current evaluation. The primary outcome was corticosteroid-free clinical remission at week 104. Results In total, 252 CD patient with at least two years of follow up were included. Of all included patients, the proportion of patients in corticosteroid-free clinical remission at week 12, 24, 52 and 104 was 32.3% (81/251), 41.4% (104/251), 39% (97/249) and 34.0% (84/247), respectively. Of the 97 patients in corticosteroid free clinical remission at week 52, 58 (59.8%) were still in corticosteroid-free clinical remission at week 104. In patients with combined clinical and biochemical disease activity at baseline (n=122), the corticosteroid-free clinical remission rates were 23.8% (29/122), 35.2% (43/122), 40.0% (48/120) and 32.8% (39/119) at week 12, 24, 52 and 104, respectively. The probability of remaining on ustekinumab treatment after 52 and 104 weeks was 64.3% and 54.8%, respectively. There were no predictive factors associated with corticosteroid-free clinical remission at week 104 on univariate and multivariate analysis. Most common adverse events were headache, skin reaction and musculoskeletal complaints. Two patients stopped ustekinumab due to an infection after 8 and 30 weeks of treatment (mild fever syndrome and moderate upper airway infection, respectively). The main reason for discontinuing treatment after 52 weeks was loss of response (66.7%). Conclusion Ustekinumab was effective and relatively safe in our real world, prospective cohort of CD patients. After 104 weeks of ustekinumab treatment, one third of patients were in corticosteroid-free clinical remission.

Abstract Background Clinical trials and observational studies have demonstrated the clinical efficacy of vedolizumab (VDZ) as maintenance therapy for Crohn’s disease (CD) and ulcerative colitis (UC). This report presents long-term data on persistence of VDZ maintenance therapy in real-world clinical practice in Belgium. Methods The Belgian VDZ Registry (ENCePP EUPAS6469) enrolled 202 VDZ-treated ulcerative colitis (UC) or Crohn’s disease (CD) adult patients (26% with no prior use of anti-TNF therapy) from 19 centres across Belgium. The median length of VDZ therapy prior to enrolment was 11 months. Patients were followed-up every 6 months after enrolment with the assessment of IBD features, use of biologics, and disease activity. Clinical remission was defined as the Harvey–Bradshaw Index (HBI) <5 or partial Mayo Score (pMS) <2. Missing value imputation (last observation carried forward) was used to partially account for missing disease activity scores. If a 6-monthly disease activity score was missing, the disease activity score from the previous 6-monthly assessment was used. Results The mean duration of VDZ therapy, including use prior to enrolment, was 31 months, with 68% of CD patients and 75% of UC patients using VDZ therapy for 48 months. Clinical remission rate after 42 months of VDZ therapy was higher in UC (84%) than CD (67%), and higher for patients without prior anti-TNF therapy (87%) than those with prior anti-TNF therapy (70%). Fifty-seven (29.4%) patients discontinued VDZ during follow-up, due to loss of response (n = 40), adverse event (n = 7), clinical remission (n = 4), pregnancy planning (n = 3), and patient choice (n = 3). Conclusion These real-world long-term Belgian data demonstrate a high persistence of VDZ maintenance therapy among both CD and UC patients, with highest clinical remission rates seen in patients with UC and those with no prior anti-TNF therapy.

Background: Prospectively and systematically collected real-world data on vedolizumab are scarce. We aimed to assess the long-term clinical effectiveness of vedolizumab in inflammatory bowel disease (IBD). Methods: This study was a prospective, observational, multicentre study. Overall, 286 patients with active IBD were included (Crohn’s disease, n = 169; ulcerative colitis, n = 117). The primary outcomes were clinical response at week 12 and clinical remission at week 52, based on the Harvey Bradshaw Index and the partial Mayo Clinic score. Secondary outcomes included clinical remission at week 12, clinical response at week 52, corticosteroid-free clinical remission at week 52, changes in biochemical measures, and health-related quality of life (HRQoL). Results: At baseline, 88% of the patients were exposed to anti-TNF and 41% of the patients with Crohn’s disease had undergone ⩾1 surgical resection. At week 12, clinical response was 27% and remission 47% in Crohn’s disease; corresponding figures in ulcerative colitis were 52% and 34%. Clinical response, remission and corticosteroid-free remission at week 52 were 22%, 41% and 40% in Crohn’s disease and 49%, 47% and 46% in ulcerative colitis, respectively. A statistically significant decrease in median faecal-calprotectin and C-reactive protein was observed at 12 and 52 weeks in patients with Crohn’s disease and ulcerative colitis. The HRQoL measures Short Health Scale and EuroQol 5-Dimensions improved in both Crohn’s disease and ulcerative colitis patients ( p < 0.001). Clinical disease activity at baseline was inversely associated with clinical remission at week 52. Conclusion: Vedolizumab proved effective for the treatment of refractory IBD in clinical practice.

Abstract Background The best choice of biological agents after failure to an anti-tumour necrosis factor (TNF)α agent in patients with Crohn’s disease (CD) is yet to be defined. Real-world data dealing with this issue are still emerging. Methods This is a multicentre retrospective study including eight UK hospitals (August 2014-April 2020). We retrospectively collected data of patients treated with ustekinumab. Clinical response and remission at 14 and 52 weeks evaluated through Physician Global Assessment (PGA) and adverse events were recorded. Predictors of clinical response were examined, and a propensity score-matched analysis with a cohort of patients treated with vedolizumab was performed. Results Overall, 282 patients (mean age 40±15, F:M ratio 1.7:1) treated with ustekinumab were included. Clinical response or remission was reached by 200/282 patients (70.9%) at 14 weeks, and by 162/259 patients (62.5%) at 52 weeks. The most common reason for discontinuation was either primary failure or loss of response, followed by the occurrence of adverse events and by the need for surgery. The rate of non-adherence was rather low (1.4%). Current smoking (OR 2.48, 95% CI 1.13-5.44; p=0.02), baseline PGA (OR 2.4, 95% CI 1.55-3.69, p&lt;0.001), and use of steroids (OR 2.42, 95% CI 1.26-4.65, p=0.008) were associated with 52-week treatment failure. Overall, 74 adverse events occurred, of which 26 were labelled as serious (8.3 per 100 person-year). After exclusion of patients without anti-TNFα exposure prior to starting ustekinumab or vedolizumab and exclusion of patients previously exposed to vedolizumab or ustekinumab, we analysed 275/282 patients (97.5%) from the ustekinumab cohort and 118/135 patients (87.4%) from the vedolizumab cohort. Propensity score analysis revealed that at 14 weeks, patients treated with ustekinumab were 38% (95% CI 25-50%; p&lt;0.001) more likely to achieve a clinical remission, while at 52 weeks, the difference of 9% (95% CI -15-33%; p=0.462) was not significant. Conclusion Ustekinumab was effective and well tolerated in this real-world cohort. While ustekinumab proved more effective at 14-week follow-up, we found no statistically significant differences in outcomes at 52 weeks.

Abstract Background Therapeutic options for inflammatory bowel disease (IBD) have increased since the introduction of tumour necrosis factor (TNF) inhibitors a few decades ago. However, direct comparisons of the effectiveness of second-line biological agents in patients with ulcerative colitis (UC) and Crohn’s disease (CD) are lacking. Methods Patients with UC or CD who experienced anti-TNF treatment failure and subsequently used vedolizumab, ustekinumab, or tofacitinib as a second-line drug were retrospectively recruited. The primary outcomes were the clinical remission rate at week 16 and the cumulative relapse rate 48 weeks after receiving induction therapy. Results A total of 94 patients with UC or CD experienced anti-TNF treatment failure and received vedolizumab (UC : 37; CD : 28), ustekinumab (CD : 16), or tofacitinib (UC : 13). The clinical remission rates were not significantly different between the vedolizumab and tofacitinib groups in UC patients (56.8% vs. 46.2%, p = 0.509). In CD patients, the clinical remission rates were not significantly different between the vedolizumab and ustekinumab groups (53.6% vs. 50.0%, p = 0.820). Moreover, the cumulative rates of clinical relapse were not significantly different between the vedolizumab and tofacitinib groups in UC patients and between the vedolizumab and ustekinumab groups in CD patients (p = 0.396 and p = 0.692, respectively). Safety profiles were also similar among the treatment groups in both UC and CD patients. Conclusion After prior anti-TNF therapy failure, vedolizumab and tofacitinib in UC patients and vedolizumab and ustekinumab in CD patients showed similarities in terms of the efficacy in inducing and maintaining a clinical response.

Context Adalimumab is a fully-human antibody that inhibits TNF alpha, with a significant efficacy for long-term maintenance of remission. Studies with this agent in Latin American Crohn’s disease patients are scarce. Objectives The objective of this study was to outline clinical remission rates after 12 months of adalimumab therapy for Crohn’s disease patients. Methods Retrospective, single-center, observational study of a Brazilian case series of Crohn’s disease patients under adalimumab therapy. Variables analyzed: demographic data, Montreal classification, concomitant medication, remission rates after 1, 4, 6 and 12 months. Remission was defined as Harvey-Bradshaw Index ≤4, and non-responder-imputation and last-observation-carried-forward analysis were used. The influence of infliximab on remission rates was analyzed by Fischer and Chi-square tests (P<0.05). Results Fifty patients, with median age of 35 years at therapy initiation, were included. Remission rates after 12 months of therapy were 54% under non-responder-imputation and 88% under last-observation-carried-forward analysis. After 12 months, remission on patients with previous infliximab occurred in 69.23% as compared to 94.59% in infliximab-naïve patients (P = 0.033). Conclusions Adalimumab was effective in maintaining clinical remission after 12 months of therapy, with an adequate safety profile, and was also more effective in infliximab naïve patients.
