Abstract Background Adalimumab (ADA) is effective as induction and maintenance therapy in Crohn’s disease (CD). Serum ADA levels have been shown to be correlated with clinical remission. Therapeutic goals have evolved based on the notion of ‘treat to target’ and the aim is to achieve deep remission. The objective of this study was to consider the association between serum ADA levels and clinical, biological, endoscopic and iconographic remission in CD. Methods From October 1, 2016 to December 31, 2018, all CD patients receiving ADA who had a serum ADA level test with anti-ADA antibodies (AAA) detection were consecutively included. We compared serum ADA levels between the following groups: patients with and without clinical remission, patients with biological remission and those with a CRP >5mg/l, patients with endoscopic remission and those with ulcerations and patients with iconographic remission and those with active radiological lesions. In addition, we defined optimal cut-off values to reach these therapeutic targets by analysing ROC curves. Results Three hudred and four patients were included corresponding to a total of 445 assays. Indications for the ADA assay were mainly for persistent disease activity in 308 (69%) samples. An immunosuppressant was initially associated with ADA treatment in 154 (35%) samples and 75 (17%) assays were performed under combotherapy. ADA concentrations were higher in patients who started ADA in combotherapy (8.3 vs. 6.6 μg/ml, p = 0.005), but not in patients treated by combotherapy at the time of dosing (8.7 vs. 7.1 μg/ml, p = 0.12). Serum levels of ADA were significantly higher in patients in remission compared with patients with active disease for clinical remission (7.9 vs. 6.3 μg/ml, p = 0.015), biological remission (9.5 vs. 5.1 μg/ml, p <0.001), endoscopic remission (10.1 vs. 6.1 μg/ml, p <0.001) and luminal iconographic remission (9.1 vs. 6.8 μg/ml, p = 0.04). ROC curves and the areas under the curve (ASC) were analysed to determine optimal cut-off values of serum ADA levels to predict these different levels of remission: 6.45 μg/ml (AUC 0, 56, p = 0.027) for clinical remission, 7.35 μg/ml (AUC 0.67, p < 0.001) for biological remission, 9.75 μg/ml (AUC 0.64, p = 0.002) for endoscopic remission and 7.80 μg/ml (AUC 0.58, p = 0.04) for luminal iconographic remission. Conclusion High levels of ADA are associated with clinical, biological, endoscopic and iconographic remission in CD. Optimal cut-off values of ADA have been identified and increase as deep remission is obtained. These results suggest that serum ADA levels should be considered to be one of the tools in the tight control strategy of CD and adapted according to pre-defined objectives (clinical, biological or mucosal).

Summary The main objectives in Crohn's disease are to avoid disease complications and preserve the patient's quality of life. Early disease control and close monitoring with specific targets to reach might be the only way to change the disease course. In two decades, we have moved from clinical response to full remission (clinical and endoscopic remission) requiring a tight monitoring of both symptoms and objective signs of inflammation. This review summarizes the concepts of tight control and treat-to-target and their potential for disease modification.

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 Treat-to-target (T2T) strategy may optimise IBD disease management. We describe interim clinical and endoscopic results of the STARDUST trial in Crohn’s disease (CD) patients, following 16 weeks (W) of ustekinumab (UST) induction. Methods STARDUST, an ongoing phase 3b randomised strategy trial, enrolled adults with moderate–severely active CD (CD activity index [CDAI] 220–450) and simple endoscopic index for CD [SES-CD] ≥3) who failed conventional therapy ±1 biologic. At W0, patients received intravenous, weight-based UST of ~6mg/kg (approved label) and at W8, subcutaneous UST 90mg. At W16, patients with CDAI reduction ≥70 points were randomised (1:1) to T2T or standard of care. Key endpoints (intention-to-treat [ITT] set, as observed) were analysed at W8 and W16: % patients in clinical remission (CDAI score <150); % patients with a clinical response (CDAI <150 or decrease vs. baseline [BL] ≥100 points); faecal calprotectin (FCal) and C-reactive protein (CRP) levels: normalisation of FCal or/and CRP; improvement ≥50% vs. BL (patients with elevated FCal and CRP subpopulations); change vs. BL in CDAI and Inflammatory Bowel Disease Questionnaire (IBDQ) total scores. Patients randomised to T2T underwent colonoscopy at W16 and were analysed for change in SES-CD score vs. BL, endoscopic response (decrease in SES-CD score ≥50% vs. BL) and endoscopic remission (SES-CD score ≤2) (central reading). Results The ITT full set included 500 patients with BL mean (SD) CDAI score 282.3 (65.8), SES-CD 13.1 (8.1), CRP 15.7 (23.4) mg/l, FCal 1741.9 (2932.1) mg/g and disease duration 9.4 (8.7) years; 58.4% previously failed 1 biologic. At W16, 79.4% of patients had a clinical response and 66.6% were in clinical remission. About half of the patients showed ≥50% improvement in FCal and CRP levels, which normalised in about 1/3 of patients. Results were similar irrespective of previous biologic (Table 1); 84% of patients in response at W16 were in clinical remission. Statistically significant changes from BL in CDAI, FCal, and CRP were observed at W8, and in IBDQ scores at W16 (Table 2). In the T2T set (n = 220; CDAI 70 responders), BL characteristics were similar to the full analysis set; SES-CD score was 13.4 (8.8). At W16, 36.8% and 11.4% of patients in the T2T set achieved endoscopic response and remission, respectively. The endoscopic response was independent of BL SES-CD score and disease duration, but numerically better for colonic vs. ileal disease. No new safety signals were reported. Conclusion STARDUST is the first T2T trial in CD patients. After 16 W following induction with UST, 2/3 of patients achieved clinical remission. Thirty-seven per cent of those randomised to the T2T arm (CDAI 70 responders) showed endoscopic response by central reading at W16. Results were similar irrespective of being bio-naïve or failing 1 biologic.

Abstract Background We studied the efficacy and safety of ustekinumab (UST) vs adalimumab (ADA) through 1 year in biologic-naïve patients (pts) with moderate-to-severe Crohn’s disease. Methods SEAVUE was a multicenter, randomized, blinded, parallel-group, active-controlled study in adults with CD Activity Index (CDAI) scores ≥220/≤450. Biologic-naïve pts failing/intolerant to conventional therapy with any size ulcer on baseline (BL) ileocolonoscopy were eligible. Pts were randomized 1:1 to UST (⁓6mg/kg IV at BL then 90mg SC every 8 weeks [Ws]) or ADA (160/80mg SC at BL/W2, then 40mg SC every 2 Ws) per US-approved regimens (no dose modifications). Primary endpoint was clinical remission at W52 (CDAI <150). Major secondary endpoints were corticosteroid-free remission, clinical response (≥100-point CDAI decrease from BL), remission in pt-reported CDAI components (PRO-2 symptom remission: abdominal pain mean daily score ≤1 and stool frequency mean daily score ≤3), and endoscopic remission (SES-CD score ≤3/0 for pts with BL score=3) at W52 and clinical remission at W16. Results 386 pts were randomized to UST or ADA. BL demographics and disease characteristics were balanced between groups and indicative of pts with early, moderate-to-severe CD (median CD duration, 2.58 years; CDAI, 289.5; SES-CD, 8.0). At W52, 65% of UST-treated and 61% of ADA-treated pts achieved clinical remission (Δ=4.0%; 95% CI, -5.5%, 13.5%; p=0.417). Major secondary endpoints, including endoscopic remission, were similar between groups (Table 1), as were remission rates at assessment points through W52. Some other secondary endpoints showed numerical (not statistical) differences between UST and ADA (Table 1). Key safety events are summarized in Table 2. Among UST-treated and ADA-treated pts, 34.0% and 40.5% had infections, 2.6% and 7.2% had serious adverse events (AEs) of worsening CD, and 6.3% and 11.3% had AEs that led to discontinuation (DC) of study drug, respectively. One ADA-treated pt had active pulmonary TB. Injection-site reactions associated with active treatment occurred in 1.0% of UST-treated and 10.3% of ADA-treated pts. Overall, 15.2% of UST-treated and 23.6% of ADA-treated pts DC before W52. Reasons for DC were primarily lack of efficacy (UST, 2.1% vs ADA, 5.1%), AEs (UST, 5.7% vs ADA, 10.7%), and withdrawal of consent (UST, 5.8% vs ADA, 5.1%). Time to treatment DC was longer with UST vs ADA (post hoc analysis). Conclusion Both UST and ADA were highly effective in this population of biologic-naïve pts. Rates of clinical remission at W52 were not statistically significantly different between treatment groups. DC rates were numerically lower for UST. Safety results were consistent with prior experience for both treatments.

Abstract Background and Aims Ustekinumab, an anti-IL12/23p40 monoclonal antibody, has been approved for Crohn’s disease [CD]. Real-life data in CD patients receiving ustekinumab intravenously [IV] during induction, followed by subcutaneous [SC] maintenance, are lacking. We assessed efficacy of ustekinumab and studied exposure-response correlations. Methods We performed a prospective study in 86 CD patients predominantly refractory or intolerant to anti-tumour necrosis factor agents and/or vedolizumab. All received ustekinumab 6 mg/kg IV induction, with 90 mg SC every 8 weeks thereafter. Endoscopic response (50% decrease in Simple Endoscopic Score for CD [SES-CD] at Week 24), endoscopic remission [SES-CD ≤2], and clinical remission [daily stool frequency ≤2.8 and abdominal pain score ≤1] were assessed at weeks 4,8,16, and 24. Further serial analyses included patient-reported outcomes [PRO2], faecal calprotectin [fCal], and ustekinumab serum levels. Results SES-CD decreased from 11.5 [8.0–18.0] at baseline to 9.0 [6.0–16.0] at week [w]24 [p = 0.0009], but proportions of patients achieving endoscopic response [20.5%] or endoscopic remission [7.1%] were low. Clinical remission rates were 39.5% at w24. After IV induction, fCal dropped from baseline [1242.9 μg/g] to w4 [529.0 μg/g] and w8 [372.2 μg/g], but increased again by w16 [537.4 μg/g] and w24 [749.0 μg/g]. A clear exposure-response relationship was observed, both during induction and during maintenance therapy, with different thresholds depending on the targeted outcome. Conclusions In this cohort of refractory CD patients, ustekinumab showed good clinical remission rates but limited endoscopic remission after 24 weeks. Our data suggest that higher doses may be required to achieve better endoscopic outcomes.

Abstract Background The STARDUST study demonstrated that ustekinumab (UST), using either a treat-to-target (T2T) or standard of care (SoC) strategy, may induce and maintain endoscopic and clinical response and remission in Crohn’s disease (CD). Primary endpoint, safety, and efficacy have been reported previously.1 Because corticosteroid (CS) sparing is an important aim of CD management, we compared the efficacy of UST T2T vs SoC in achieving CS-free clinical remission and endoscopic response. Methods Adult patients (pts) with moderate–severely active CD who were CDAI 70 responders after 16 weeks (W) of induction, comprising a single dose of UST 6 mg/kg iv followed by UST 90 mg SC at W8, were randomized to either T2T or SoC arms. In the T2T arm, choice of UST maintenance dosage (q12w or q8w) was based on endoscopic improvement at W16, followed by clinical and biomarker-directed dose escalation up to q4w; in the SoC arm, UST q12w or q8w dosage was based on EU SmPC. Primary endpoint was endoscopic response (Simple Endoscopic Score in CD [SES-CD] decrease from baseline [BL] ≥50%) at W48. For pts on CS at W16, CS tapering was mandatory. At W48, CS-free clinical remission (CDAI <150 and no CS for ≥30 days) and CS-free endoscopic response (reduction from BL in SES-CD ≥50% and no CS for ≥30 days) were evaluated. Results Of 500 pts enrolled, 441 achieved a CDAI 70 response at W16 and were randomized to T2T (n=220) or SoC (n=221); 79.1% and 87.3%, respectively, completed W48. Among clinical remitters and responders at W16 (start of CS tapering), in both T2T and SoC arms more than 70% were still in remission or response at W48 (Figure 1). CS use throughout 48 weeks of treatment is summarized in Table 1. At W48, in T2T and SoC arms similar rates were noted for CS-free endoscopic response (33.6% and 28.5%, respectively) and CS-free clinical remission (56.4% and 63.3%, respectively). Notably, in T2T and SoC arms the CS-free clinical remission rate among pts on CS at BL was 44.1% and 45.1%, respectively (Figure 2). Among W48 endoscopic responders (T2T, n=83; SoC, n=66), CS-free endoscopic response rate was 89.2% and 95.5%, respectively; among W48 clinical remitters (T2T, n=135; SoC, n=154), CS-free clinical remission rate was 91.9% and 90.9%, in T2T and SoC arms, respectively. Conclusion Pts treated with UST under T2T or SoC strategies achieved similar rates of CS-free clinical remission and endoscopic response over 48 weeks. Overall for pts on CS at BL, UST reduced the need for CS while achieving response/remission. Most (>89%) pts with endoscopic response/clinical remission at W48 were also CS-free responders/remitters.

Abstract Background Recent progress in deciphering the complex pathogenesis of Crohn’s disease (CD) has yielded several effective biologicals. However, ambitious therapeutic goals remain unfulfilled as almost 30% of patients are primary non-responders to a particular biological. This underscores the need for easy-to-implement biomarkers that predict (non-)remission. We aimed to identify serum protein biomarkers that predict endoscopic remission in CD patients. Methods Serum samples from 169 consecutive CD patients with active endoscopic disease (presence of ulcerations) before starting a biological [infliximab (IFX), adalimumab (ADA), vedolizumab (VDZ) or ustekinumab (UST)] to which they were naïve were collected. Patients were prospectively followed with endoscopic re-assessment after 6–12 months. There were 102 patients (Table 1) with endoscopic remission (SES ≤ 2 or disappearance of all ulcers), whereas 67 showed no improvement. Two independent and complementary proteomic platforms were used: 644 proteins belonging to predesigned assays were quantified using Proximity Extension Assay (PEA) technology (Olink Proteomics AB, Sweden). Second, wide protein discovery mass spectrometry (MS)-based technic (Caprion, Canada) was used and quantified another 985 proteins. A multivariate modelling framework was then applied on a randomly selected training sub-cohort (85%). Predictive performance of identified panels was assessed on the remaining test sub-cohort (15%). We sought to implement the same framework on the drug-specific subgroups; however, train/test splitting was not possible in IFX or ADA subgroups due to very few observations in the non-remission arms which diminishes the possibility for reliable predictive modelling. Results Applying the modelling framework on training sets from the general cohort, VDZ subgroup and UST subgroup, proteomic panels were selected and consisted of 26, 6 and 8 proteins, respectively, and showed high performance in the test sets (Table 2). VDZ and UST panels shared only 2 proteins each with the general panel, and had no predictive power (accuracy ≤ 0.5) when used to predict other subgroups, making them specific to their respective drugs. Selected proteins are involved among others in pro-inflammatory, extracellular matrix modelling, coagulation and cellular-vascular interaction pathways (Table 3). Conclusion Applying a multivariate machine learning algorithm on a wide pool of serum proteomics analysed through two discovery technics, we were able to identify 3 proteomic panels that can predict endoscopic (non)remission in patients with CD. Exact implication of these proteins in intestinal inflammation and a validation in an independent cohort is being further investigated.

Abstract Background There are limited data of long-term ustekinumab administered according to the doses recommended in the UNITI studies. The objective of this study was to assess the real-world, long-term effectiveness of ustekinumab in refractory Crohn’s disease (CD) (LONG-CROHNUSK Study). Methods Multicentre study of CD patients starting ustekinumab at the recommended dose based on weight ~6 mg/kg IV week 0, 90 mg SC week 8 and maintenance 90 mg SC every 8 or 12 weeks and with 1 year of follow-up. Values for Harvey-Bradshaw Index (HBI), endoscopic activity, C reactive protein (CRP) and faecal calprotectin (FC) were recorded at baseline and at weeks 26 and 52. Demographic and clinical data, previous treatments, adverse events (AEs), surgeries and hospitalisations were documented. Potential predictors of clinical and endoscopic remission were examined. Results Four hundred and seven patients were analysed (Table 1). For the maintenance dose, ustekinumab 90 mg was administered SC every 12, 8 and 4 weeks in 56 (14%), 318 (84.5%) and 7 (1.5%) patients, respectively. An interval reduction was applied for 118 patients (29%). Before 52 weeks, treatment discontinuation occurred in 71 patients (17%). At baseline, 295 (72%) had an HBI >4 points. Of these, 169 (57%) and 190 (64%) achieved clinical remission at weeks 26 and 52, respectively. FC levels returned to normal (<250 μg/g) in the 44% and 54% of the patients at weeks 26 and 52, respectively. CRP returned to normal (<3 mg/l) in 36% and 37% of the patients at weeks 26 and 52 respectively. HBI, FC, and CRP values over time are shown in Figure 1. Of the 159 patients with endoscopy at 52 weeks, 25 (16%) were in remission and 58 (36%) presented mild activity. Thirty-eight (9.3%) patients worsened extra-intestinal manifestations and 33 (8%) their perianal disease. AEs were recorded in 54 patients, 73 were hospitalised and 53 had surgery. An association was shown for fewer previous anti-TNF agents and ileal localisation with clinical remission, and for endoscopic severity at baseline with poor response. No factors correlated with endoscopic remission. Conclusion This is the first study to show the real-world long-term effectiveness, endoscopic improvement and safety of ustekinumab administered according to the recommended induction regimen in a cohort of highly refractory CD patients.

IntroductionCrohn’s disease is a chronic inflammatory disease of the gastrointestinal tract with an increasing incidence and prevalence worldwide. The early use of anti-­tumour necrosis factor agents, such as infliximab, in patients with an aggressive form of Crohn’s disease has become part of routine practice. However, infliximab has limitations, and early surgery might benefit patients more. The objective of this study was to compare laparoscopic bowel resection with infliximab treatment in patients with moderately or severely active Crohn’s disease with respect to endoscopic remission. The laparoscopic bowel resection combined with infliximab treatment trial is the first randomised controlled trial to demonstrate if early surgery can improve the outcome of patients with Crohn’s disease with limited non-stricturing disease treated with infliximab.Methods and analysisThis is a randomised, open-label, controlled trial at Renji Hospital. In this study, a total of 106 adult patients aged 18–80 years with moderately or severely active and steroid-dependent or steroid-resistant Crohn’s disease of the distal ileum will be randomly assigned in a 1:1 ratio to the control and surgery groups. The primary outcome is 12-month endoscopic remission measured by the Simple Endoscopic Score for Crohn’s Disease in the control group and the Rutgeerts score in the surgery group. The secondary outcomes are clinical remission, surgery rate, quality of life, Crohn’s disease-related medical costs and Crohn’s disease-related morbidity. The patients will be followed up every 6 months after randomisation through intestinal magnetic resonance enterography and colonoscopy for either 3 years or until clinical remission.Ethics and disseminationAll participants will provide informed consent. The protocol has been approved by the Medical Ethical Committee of the Academic Medical Center in Shanghai (No KY2019-180). Results will be disseminated through peer-reviewed journals and scientific conference presentations.Trial registration numberChiCTR2000029323.
