RESUMO
BACKGROUND & AIMS: The aim of this study was to assess the long-term effectiveness and safety of risankizumab maintenance treatment in a large real-world cohort of patients with Crohn's Disease (CD). METHODS: From May 2021 to August 2023, all consecutive patients with CD treated with risankizumab in 25 GETAID centers have been retrospectively included. The primary endpoint was steroid-free clinical remission (Harvey Bradshaw Index [HBI] <5) at 52 weeks. RESULTS: Of the 174 patients included, 99%, 93%, and 96% had been previously exposed to anti-TNF, vedolizumab, and ustekinumab, respectively. All patients had received ≥3 biologics, and 108 (62%) had previous intestinal resection. Median follow-up was 13.7 months (interquartile range, 10.0-18.1 months). The rates of steroid-free clinical remission and clinical remission at week 26 were 47% (72/152) and 52% (79/152), and 46% (58/125), and 48% (60/125) at week 52, respectively. Risankizumab persistence rates were 94%, 89%, and 79% at weeks 12, 26, and 52, respectively. At the end of follow-up, 45 (45/174; 26%) patients had discontinued risankizumab (loss of response, 42%; primary failure, 37%; intolerance, 13%). Thirty-six patients (36/174; 20.9%) were hospitalized, and 22 (22/174; 12.6%) required intestinal resection. Fifty-one patients (29%) had an adverse event, including 26 (15%) serious adverse events (CD flare, n = 17). One death (myocardial infarction) and one cancer (papillary thyroid carcinoma) were observed. CONCLUSION: This is the first real-life study to report long-term outcomes in patients with refractory CD treated with risankizumab. One-half of the patients achieved steroid-free clinical remission after 1 year, and the safety profile was consistent with the literature.
RESUMO
BACKGROUND & AIMS: Crohn's disease (CD) patients included in the Tailored Treatment With Infliximab for Active Crohn's Disease (TAILORIX) trial started infliximab in combination with an immunosuppressant for 1 year. The aim of the present study was to determine the long-term disease course beyond the study period. METHODS: We compared the outcomes of patients who did or did not reach the primary end point of the TAILORIX trial, defined as sustained corticosteroid-free clinical remission from weeks 22 through 54, with no ulcers on ileocolonoscopy at week 54. The primary outcome of this follow-up study was the progression-free survival of CD defined by anal or major abdominal surgery, CD-related hospitalization, or the need for a new systemic CD treatment. RESULTS: The 95 patients (median disease duration, 4.5 mo; interquartile range, 1.0-56.6 mo) analyzed, including 45 (47%) who achieved the primary end point, were followed up for a median duration of 64.2 months (interquartile range, 57.6-69.9 mo) after the end of the study period. There was no significant difference in CD progression-free survival at 1, 3, and 5 years between patients who achieved the TAILORIX primary end point and patients who did not (P = .64). No difference was observed between both groups for each component of CD progression: anal surgery, major abdominal surgery, CD-related hospitalization, or the need for a new systemic CD treatment. CONCLUSIONS: Achieving a sustained clinical remission off steroids with complete endoscopic remission in this cohort of 95 patients with early CD was not associated with less disease progression. Prospective trials to define the therapeutic goals that change the natural history of CD and prevent complications are needed.

BACKGROUND: The aim of the study was to identify factors associated with a radiological response and to assess the impact of radiological improvement in long-term outcomes in small bowel (SB) Crohn's disease (CD) patients. METHODS: We performed a retrospective study from June 2011 to June 2017 in the tertiary center, Claude Huriez Hospital in Lille, France. All SB CD patients, who underwent two magnetic resonance enterographies (MRE) 3-12 months apart, with at least 1-year follow-up after the second MRE, were included. Signs of radiological inflammation were identified by two expert radiologists in CD. Patients were classified as radiological responders (RR) and non-responders (NR). Hospitalization rates, adjustment of treatment, and surgical or endoscopic interventions were assessed and compared between RR and NR. Factors associated with a radiological response were also studied using the Cox model. RESULTS: One hundred and fifteen SB CD patients were included with a median follow-up of 17 months (IQR 11.6-28.3). There were 54 (47%) RR and 61 (53%) NR. The risk of surgical or endoscopic intervention was higher in NR than RR (p = 0.04), and the median delay until a surgical or endoscopic intervention was shorter in NR (p = 0.04). Multifocal disease, a hypersignal on diffusion-weighted or dynamic contrast-enhanced imaging, a stricture, or a fistula was significantly associated with a decreased probability of a radiological response (p < 0.05). CONCLUSION: This study shows that a radiological response is associated with a decreased risk of surgical or endoscopic intervention and should be considered as a therapeutic target in CD patients.

INTRODUCTION: The aim of this study was to evaluate the association between serum ustekinumab (UST) trough levels and response to induction and maintenance UST treatment in refractory Crohn's Disease (CD) patients. METHODS: We performed a prospective study including CD patients who received UST from September 2015 to January 2017. Patients received 90 mg of UST subcutaneously at weeks 0, 4, and 12, then every 8 weeks. Two cohorts of patients were analyzed: an induction cohort and a maintenance cohort. We evaluated clinical, biological, and imaging/endoscopic response to UST treatment. UST trough levels and anti-UST antibodies were dosed at weeks 12 and 28 in the induction cohort, and at a single time point in the maintenance cohort. RESULTS: Forty-nine patients were enrolled in the maintenance cohort. Mean concentrations of UST were 1.88 ± 1.40 µg/mL. UST trough levels were not significantly different in patients with or without clinical, biological, or imaging/endoscopic responses to UST treatment (p > 0.11). Twenty-three consecutive patients were included in the induction cohort. At week 12, mean UST concentrations were 1.45 ± 1.15 µg/mL. Patients with a biological response to UST treatment had significant higher serum UST trough concentration (median 1.72 µg/mL) than non-responders (median 0.56 µg/mL, p = 0.02). A UST trough level ≥ 1.10 µg/mL at week 12 was associated with a biological response to UST treatment at 6 months. CONCLUSION: UST trough levels were associated with a biological response at the end of the induction phase. In patients with low levels of UST, optimization treatment may be necessary to obtain a sustained response.

BACKGROUND: Phase III trials have demonstrated the efficacy of risankizumab in moderate-to-severe Crohn's disease (CD), but no real-world data are currently available. We aimed to assess the short-term effectiveness and safety of risankizumab in patients with CD. METHODS: From May 2021 to May 2022, all patients with refractory luminal CD treated with risankizumab in 22 French GETAID centres were retrospectively included. The primary endpoint was steroid-free clinical remission at week 12 (Harvey-Bradshaw [HB] score <5). Secondary endpoints included clinical response (≥3-point decrease of HB score and/or (HB) score <5), biochemical remission (CRP ≤ 5 mg/L), need for CD-related surgery and adverse events. RESULTS: Among the 100 patients included, all have been previously exposed to anti-TNF agents, 94 to vedolizumab, 98 to ustekinumab (all exposed to at least three biologics) and 61 had a previous intestinal resection. All but three (97%) received a 600 mg risankizumab intravenous induction at weeks 0-4-8. At week 12, steroid-free clinical remission was observed in 45.8% of patients, clinical remission in 58% and clinical response in 78.5%. In subgroup analysis restricted to patients with objective signs of inflammation at baseline (n = 79), steroid-free clinical remission at week 12 was observed in 39.2% of patients. Biochemical remission was observed in 50% of patients. Six patients discontinued risankizumab before the week 12 visit due to lack of efficacy. CD-related hospitalisation was needed in six patients, and three underwent intestinal resection. In multivariable analysis, only a history of ustekinumab loss of response (vs primary failure) (odds ratio (OR), 2.80; 95% CI: 1.07-7.82; p = 0.041) was significantly associated with clinical remission at week 12. Twenty adverse events (AE) occurred in 20 patients including 7 serious AE corresponding to 6 CD exacerbation and one severe hypertension. CONCLUSION: In a cohort of highly refractory patients with luminal CD and multiple prior drug failures including ustekinumab, risankizumab induction provided a clinical response in about 3 out of 4 patients and steroid-free clinical remission in about half of patients.

BACKGROUND: Although adalimumab is effective in Crohn's disease, most patients experience a loss of response over time. The aim of the present study was to evaluate efficacy and safety of adalimumab dose escalation and identify predictors of a clinical response in Crohn's disease patients with a secondary loss of response. METHODS: We performed a retrospective and observational study including all Crohn's disease patients who underwent dose escalation of adalimumab after a secondary loss of response from 2007 to 2015. RESULTS: A clinical response was observed in 99/124 (79%) patients at 3 months and in 62/107 (61%) patients at 12 months. The predictive factors of response to ADA dose escalation at 12 months on multivariate analysis were: maintenance therapy of 40mg every week rather than 80mg every other week (OR 3.64, 95% CI: 1.28-10.37) and a CRP level≤5mg/L at adalimumab dose escalation (OR 6.64, 95% CI: 1.40-27.53). Adalimumab was withdrawn in 4 patients due to side effects. CONCLUSIONS: Adalimumab dose escalation is an effective and well-tolerated therapeutic option in patients with secondary loss of response. A 40mg every week optimized regimen was predictive of a response to ADA dose escalation.

BACKGROUND: Infliximab (IFX) is effective in inducing and maintaining remission in patients with luminal and anoperineal Crohn's disease (CD). However, treatment failure within 12 months after initiating IFX is observed in a significant proportion of patients. The aim of the present study was to determine whether the body mass index (BMI) affects response to IFX during the first year of treatment in patients with CD. METHODS: All patients with luminal CD who began IFX between January 2010 and May 2014 were prospectively included. BMI was calculated before IFX treatment was begun, and patients were divided into 3 groups: normal BMI (BMI < 25 kg/m), overweight patients (BMI of 25.0-30 kg/m), and obese patients (BMI > 30.0 kg/m). The primary outcome was to evaluate the rate and delay of IFX optimization during the first year of treatment among normal weight, overweight, and obese patients. RESULTS: One hundred forty patients were included. Demographic and clinical characteristics at IFX initiation were comparable among the 3 groups. Within 12 months after the initiation of IFX, the rate of IFX optimization was significantly higher in overweight and obese patients than in the normal BMI group: 52%, 56%, and 20%, respectively (P = 0.0002). The median time until optimization of IFX was significantly shorter in overweight and obese patients than in the normal BMI group: 7, 7, and 10 months, respectively (P = 0.03). A BMI >25 kg/m was significantly associated with IFX optimization within 12 months on multivariate analysis. CONCLUSION: This is the first study to show that optimization of IFX is more frequent and faster in obese and overweight patients with CD and occurs within 12 months after beginning IFX, suggesting that an induction regimen with higher doses of IFX and a tight control of IFX concentrations may be needed in these patients.
