Real-world evidence of combined treatment of biologics and exclusive enteral nutrition in patients with ileum-dominant Crohn's disease: A multicenter study. Clin Nutr 2024; 43:1291-1298. [PMID: 38663050 DOI: 10.1016/j.clnu.2024.04.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 03/26/2024] [Accepted: 04/11/2024] [Indexed: 05/31/2024]
Abstract
BACKGROUND & AIMS Although biologics were prescribed to achieve and maintain clinical remission of active Crohn's disease (CD), almost half of patients experienced a loss of response or intolerance. Here, we investigated the efficacy of combined treatment of biologics and 16-weeks exclusive enteral nutrition (EEN) in moderate-to-severe CD patients with small intestine lesions. METHODS This was a real-world, multicenter retrospective study, from October 2016 to March 2023, medical records of patients registered at three IBD centers were reviewed for patients with ileal or ileocolonic CD in moderate-to-severe activity. All patients received treatment of biologics with concomitant 16-week EEN (BioEEN) or biologics alone (Bio). The clinical outcomes and endoscopic outcomes were assessed at week 16 and 52. RESULTS There was no statistically significant difference between Bio (97 patients) and BioEEN group (100 patients) at baseline for demographic and clinical characteristics. Compared to treatment with biologics alone, patients with BioEEN treatment achieved higher rates of clinical response (95.0% vs. 66.0%), clinical remission (87.0% vs. 52.6%), endoscopic response (91.4% vs. 47.4%) including mucosal healing (85.7% vs. 23.7%) at week 16. The superiority of BioEEN sustained in maintenance, with 84.7% (vs. 49.1%) clinical response, 77.8% (vs. 38.6%) clinical remission, 69.2% (vs. 32.6%) endoscopic response and 51.9% (vs. 18.6%) mucosal healing at week 52. CONCLUSIONS Combined treatment of biologics and 16-week EEN was an efficient therapeutic strategy with affirmative effectiveness for small intestine diseases of active CD.

FARMACIA HOSPITALARIA 2024:S1130-6343(24)00005-9. [PMID: 38570210 DOI: 10.1016/j.farma.2024.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 01/05/2024] [Accepted: 01/09/2024] [Indexed: 04/05/2024] Open
Abstract
BACKGROUND Adalimumab biosimilar MSB11022 (Idacio ®) has been approved for the same indications as its originator (Humira ®), based on findings from clinical trials in plaque psoriasis. Data on its efficacy and safety in inflammatory bowel disease, however, are scarce. METHODS Retrospective, observational study of 44 patients with inflammatory bowel disease: 30 were treated with originator adalimumab, 5 were directly started on MSB11022, and 9 switched from originator to biosimilar adalimumab. To evaluate the effectiveness of the use of adalimumab in inflammatory bowel disease, both laboratory markers (fecal calprotectin and C-reactive protein) and scales that measure the activity of inflammatory bowel disease using specific scales (Harvey-Bradshaw Index (HBI) have been usEd.) for Crohn's disease and Mayo Score for Ulcerative Colitis. Efficacy was evaluated by recording the adverse effects that could occur with the administration of adalimumab (original or biosimilar). The success of the switch was determined by analyzing meaningful differences in effectiveness and safety criteria. Concomitant therapy and the need for dose intensification were also analyzed. Objective of this study was to assess the effectiveness and safety of biosimilar adalimumab in adalimumab-naïve patients and patients switched from originator adalimumab. RESULTS No significant differences were observed in clinical disease activity (P=.317) or biochemical parameters [fecal calprotectin (P=.445) and C-reactive protein P=.661)] after the switch from the originator adalimumab to MSB11022. There was not a significant reduction in the concomitant use of corticosteroids and thiopurines (P=.157). No emergency room visits or hospitalizations were observed during the study period and none of the patients experienced serious adverse effects. CONCLUSIONS Between originator adalimumab and biosimilar-start cohorts, no differences were observed, between originator adalimumab and switch cohorts, no significant differences were found either, and with the pre- and post-switch to biosimilar comparison, 2 of the 9 patients experienced AEs after the switch. The biosimilar showed a favorable safety profile (one patient with a serious adverse effect (rash) with biosimilar discontinued treatment) and no significant changes to clinical or biochemical parameters were observed after the switch.

Abstract
Ulcerative colitis (UC) and Crohn’s disease (CD) are part of Inflammatory Bowel Diseases (IBD) and have pathophysiological processes such as bowel necrosis and enteric neurons and enteric glial cells. In addition, the main inflammatory mediator is related to the tumor necrosis factor-alpha (TNF-α). TNF-α is a me-diator of the intestinal inflammatory processes, thus being one of the main cytokines involved in the pathogenesis of IBD, however, its levels, when measured, are present in the serum of patients with IBD. In addition, TNF-α plays an important role in promoting inflammation, such as the production of interleukins (IL), for instance IL-1β and IL-6. There are two receptors for TNF as following: The tumor necrosis factor 1 receptor (TNFR1); and the tumor necrosis factor 2 receptor (TNFR2). They are involved in the pathogenesis of IBD and their receptors have been detected in IBD and their expression is correlated with disease activity. The soluble TNF form binds to the TNFR1 receptor with, and its activation results in a signaling cascade effects such as apoptosis, cell proliferation and cytokine secretion. In contrast, the transmembrane TNF form can bind both to TNFR1 and TNFR2. Recent studies have suggested that TNF-α is one of the main pro-inflammatory cytokines involved in the pathogenesis of IBD, since TNF levels are present in the serum of both patients with UC and CD. Intravenous and subcutaneous biologics targeting TNF-α have revolutionized the treatment of IBD, thus becoming the best available agents to induce and maintain IBD remission. The application of antibodies aimed at neutralizing TNF-α in patients with IBD that induce a satisfactory clinical response in up to 60% of patients, and also induced long-term maintenance of disease remission in most patients. It has been suggested that anti-TNF-α agents inactivate the pro-inflammatory cytokine TNF-α by direct neutralization, i.e., resulting in suppression of inflammation. However, anti-TNF-α antibodies perform more complex functions than a simple blockade.

Abstract
INTRODUCTION Dose escalation is one of the treatment approaches studied and suggested in advanced therapies for Crohn's disease (CD) and ulcerative colitis (UC). This study aimed to identify and characterize the dosing escalation patterns of advanced therapies in CD and UC. METHODS Two systematic literature reviews (SLRs) were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. MEDLINE®, Embase®, and Cochrane Library were searched for articles published between January 2011 and October 2021 and limited to non-interventional studies in English language. Congress and bibliographic searches were also conducted. Articles were screened by two independent researchers. Dose escalation patterns were described and summarized considering the regional regulatory label recommendation (in North America [NA] or outside of North America [ONA]). RESULTS Among 3190 CD and 2116 UC articles identified in the Ovid searches, 100 CD and 54 UC studies were included in the SLR, with more studies conducted ONA. Most studies reported an initial maintenance dose pattern aligned with the lower starting dose per local regulatory label; however, several ONA studies (n = 13 out of 14) reported ustekinumab every 8 weeks as starting maintenance pattern in CD. In ONA studies, the median within-guideline escalation rates in CD and UC were 43% in ustekinumab (CD only), 33% and 32% for vedolizumab; 29% and 39% for adalimumab; and 14% and 10% for infliximab. Evidence regarding dose escalation patterns for tofacitinib, certolizumab pegol, and golimumab was limited. Some dose escalation patterns outside of label recommendations were observed including ustekinumab every 8 weeks to every 4 weeks and vedolizumab every 8 weeks to every 6 weeks. CONCLUSION Dose escalation strategies are widely documented in the literature. The reported dose escalation patterns and escalation rates vary by region and by CD and UC. Most escalation patterns reported were aligned with regulatory recommendations while some reported more diverse or aggressive dose escalation. PROSPERO REGISTRATION CRD42021289251.

Abstract
BACKGROUND Crohn's disease (CD) and ulcerative colitis (UC) are chronic diseases that result from the deregulation of the mucosal immune system of the gastrointestinal tract. The use of biological therapies, including infliximab (IFX), is one of the strategies to treat both CD and UC. The IFX treatment is monitored by complementary tests, namely: fecal calprotectin (FC); C-reactive protein (CRP); and endoscopic and cross-sectional imaging. Besides, serum IFX evaluation and antibody detection are also used. OBJECTIVE To evaluate trough levels (TL) and antibodies in a population with inflammatory bowel (IBD) disease undergoing treatment with IFX, and the factors that might impact the treatment effectiveness. METHODS Retrospective, cross-sectional study with patients with IBD that were assessed for TL and antibody (ATI) levels in a southern Brazilian hospital, from June 2014 to July 2016. RESULTS The study assessed 55 patients (52.7% female) submitted to serum IFX and antibody evaluations (95 blood samples, 55 first test; 30 second test, and 10 as third testing. Forty-five (47.3%) cases were diagnosed with CD (81.8%), and ten with UC (18.2%). Serum levels were adequate in 30 samples (31.57%), subtherapeutic in 41 (43.15%), and supratherapeutic in 24 (25.26%). IFX dosages were optimized for 40 patients (42.10%), maintained for 31 (32.63%), and discontinued for 7 (7.60%). The intervals between infusions were shortened in 17.85% of the cases. In 55 tests (55.79%), the therapeutic approach was exclusively defined according to IFX and/or serum antibody levels. The assessment of patients one year later indicated that: the approach was maintained with IFX for thirty-eight patients (69.09%); the class of biological agent was changed for eight (14.54%); changes using the same class of biological agent occurred for two patients (3.63%); the medication was discontinued and not replaced for three patients (5.45%), and four patients (7.27%) were lost to follow-up. CONCLUSION There were no differences in TL between groups with or without immunosuppressants, serum albumin (ALB), erythrocyte sedimentation rate (ESR), FC, CRP, and endoscopic and imaging examinations. Current therapeutic approach could be maintained for almost 70% of patients. Thus, serum and antibody levels are a useful tool in the follow-up of patients undergoing maintenance therapy and after treatment induction in patients with inflammatory bowel disease.

Abstract
This commentary summarizes a collection of key references published within the last ten years, and identifies pharmacologic research directions to improve treatment access and success through greater biosimilar or “follow-on” biologic utilization combined with other targeted small molecule agents that possess unique pathophysiologic mechanisms for inflammatory bowel diseases (IBD) in adult and pediatric patients. Since they are not identical to the originator or reference biologic agent, all biosimilars are not generically equivalent. However, in the US and other countries, they are considered therapeutically interchangeable if the manufacturer has demonstrated no clinically meaningful differences from the reference product. Comparisons of different clinical initiation and switching scenarios are discussed with reference to interchangeability, immunogenicity, nocebo effect, cost effectiveness, and time courses for discontinuation rates.

Abstract
Ulcerative colitis (UC) and Crohn's disease (CD) are chronic and multifactorial diseases that affect the intestinal tract, both characterized by recurrent inflammation of the intestinal mucosa, resulting in abdominal pain, diarrhea, vomiting and, rectal bleeding. Inflammatory bowel diseases (IBD) regroup these two disorders. The exact pathological mechanism of IBD remains ambiguous and poorly known. In genetically predisposed patients, defects in intestinal mucosal barrier are due to an uncontrolled inflammatory response to normal flora. In addition to the genetic predisposition, these defects could be triggered by environmental factors or by a specific lifestyle which is widely accepted as etiological hypothesis. The involvement of the CD40/CD40L platelet complex in the development of IBD has been overwhelmingly demonstrated. CD40L is climacteric in cell signalling in innate and adaptive immunity, the CD40L expression on the platelet cell surface gives them an immunological competence. The IL-1, a major inflammation mediator could be involved in different ways in the development of IBD. Here, we provide a comprehensive review regarding the role of platelet CD40/CD40L in the pathophysiological effect of IL-1 in the development of Crohn's disease (CD). This review could potentially help future approaches aiming to target these two pathways for therapeutic purposes and elucidate the immunological mechanisms driving gut inflammation.

Abstract
Introduction There is growing evidence that intestinal proteases have a role in the pathogenesis of gastrointestinal inflammatory diseases. Inflammatory bowel disease (IBD), which includes Crohn’s disease (CD) and ulcerative colitis (UC), has an additional source of proteases represented by infiltrated and activated inflammatory cells. The aim of our study was to determine proteolytic system activity in patients with CD and UC. We limited the number of proteases tested by determining proteases active in acidic, neutral and alkaline pH. Materials and Methods The study included 40 patients with IBD – 20 CD patients and 20 UC patients. The control group consisted of 20 healthy subjects. Among the 20 CD patients, 17 were treated with aminosalicylates, 14 with azathioprine, and 4 with corticosteroids, while 8 patients were undergoing biological treatment. Among the 20 UC patients, 19 were treated with aminosalicylates, 8 with azathioprine, and 3 with corticosteroids. The total protein concentration was assayed by the Lowry method. The optimal pH was assayed in pH from 2.2 to 12.8, separated by 0.2 intervals. Proteolytic activities were determined against different substrates (gelatine, haemoglobin, ovalbumin, albumin, cytochrome C, and casein), and haemoglobin was the optimal substrate. Protease activities were determined according to Anson method. Determination of the activities of natural inhibitors of acidic, neutral and alkaline proteases is based on the Lee and Lin method. Results Decreases were observed in the activities of acid proteases (pH 5), alkaline proteases (pH 7), and neutral proteases (pH 7.6 and 8.6) in the groups of CD patients in remission in comparison with the active phase. In the group of patients with biologically treated CD patients, acid protease activity (pH 5.0) was lower than in CD patients not receiving biological treatment. Activities of neutral (pH 7.0) and alkaline (pH 7.6 and 8.6) proteases in the plasma of patients with UC in remission were lower in comparison to the active phase. Activities of acid (pH 5.0) and alkaline (8.6) protease inhibitors were higher in CD patients in the active phase in comparison to remission. In UC patients with exacerbation of the disease, the activity of alkaline (pH 8.6) protease inhibitors was increased compared to remission. Conclusion 1. Our research may suggest that the immunomodulatory treatment used in IBD, aimed at reducing the level of leukocytes and reduction of inflammation, may contribute to a reduction in protease activity. 2. The decrease of protease activities in patients with CD and UC in remission may be a marker suggesting the patients’ response to the treatment.

Background and objectives: The biological treatment is a promising therapeutic option for ulcerative colitis (UC) patients, being able to induce subclinical and long-term remission. However, the relatively high costs and the potential toxicity have led to intense debates over the most appropriate criteria for starting, stopping, and managing biologics in UC. Our aim was to build a machine learning (ML) model for predicting disease activity at one year in UC patients treated with anti-Tumour necrosis factor α agents as a useful tool to assist the clinician in the therapeutic decisions. Materials and Methods: Clinical and biological parameters and the endoscopic Mayo score were collected from 55 UC patients at the baseline and one year follow-up. A neural network model was built using the baseline endoscopic activity and four selected variables as inputs to predict whether a UC patient will have an active or inactive endoscopic disease at one year, under the same therapeutic regimen. Results: The classifier achieved an excellent performance predicting the disease activity at one year with an accuracy of 90% and area under curve (AUC) of 0.92 on the test set and an accuracy of 100% and an AUC of 1 on the validation set. Conclusions: Our proposed ML solution may prove to be a useful tool in assisting the clinicians’ decisions to increase the dose or switch to other biologic agents after the model’s validation on independent, external cohorts of patients.

Abstract
BACKGROUND AND AIMS Therapeutic drug monitoring (TDM) of infliximab (IFX) and anti-infliximab antibodies (ATIs) is essential for treatment optimisation in inflammatory bowel disease (IBD) patients. The aim of this study was to estimate and compare the agreement and accuracy between a new rapid test and three established enzyme-linked immunosorbent assays (ELISAs) to quantify ATIs levels, and to evaluate the impact of exogenous IFX on the performance of these assays. METHODS We analysed 200 serum samples from 57 IBD outpatients in IFX induction or maintenance therapy at six IBD centres in Portugal. ATI levels were quantified using the rapid test Quantum Blue® (QB) Anti-Infliximab (Bühlmann) and three established ELISAs: In-House, Theradiag (Lisa Tracker Anti-Infliximab), and Immundiagnostik (IDKmonitor Infliximab). ATIs were quantified in patients' serum samples and spiked samples with exogenous IFX, based on analytical and clinical cutoffs. Qualitative agreement and accuracy were estimated by Cohen's kappa (k) with 95% confidence intervals. RESULTS ATIs quantification with clinical cutoffs showed a slight agreement between QB rapid test and In-House [k = 0.163 (0.051-0.276)] and Immundiagnostik [k = 0.085 (0.000-0.177)]. Regarding IFX/ATIs status, the QB rapid test showed a substantial agreement with Theradiag [k = 0.808 (0.729-0.888)] and a fair agreement with In-House [k = 0.343 (0.254-0.431)] and Immundiagnostik [k = 0.217 (0.138-0.297)]. The QB rapid test could not detect ATI-positive levels in samples with exogenous IFX at 5-300 µg/ml. Interference on ATIs detection was observed at exogenous IFX ⩾30 µg/ml for In-house and Immundiagnostik assays. CONCLUSION QB rapid test is only suitable to detect ATI-positive levels in the absence of IFX.

Optimization of azathioprine dose in combined treatment with anti-TNF-alpha in inflammatory bowel disease. GASTROENTEROLOGIA Y HEPATOLOGIA 2020; 44:337-345. [PMID: 33272733 DOI: 10.1016/j.gastrohep.2020.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 09/28/2020] [Accepted: 10/01/2020] [Indexed: 11/22/2022]
Abstract
INTRODUCTION The dose of thiopurine drugs in combined treatments with anti-TNF in inflammatory bowel disease (IBD) has not been clearly established. The purpose of this study is to assess whether the dose of azathioprine influences clinical and biochemical response/remission rates, and anti-TNF drug levels/antibody formation. MATERIAL AND METHODS Patients with IBD on combined maintenance treatment with azathioprine and infliximab or adalimumab were selected. Based on the dose of azathioprine, two groups were defined (standard: 2-2.5mg/kg/day; and decreased: less than 2mg/kg/day). RESULTS In the IFX group, there were no statistically significant differences (p=0.204) in the rates of remission (39% vs 41.3%), response (10% vs 21.7%) or failure (51.5% vs 37%) depending on the dose of thiopurine drugs. No differences were found between AZA-dose dependent IFX levels (2.46 vs 3.21μg/mL; p=0.211). In the adalimumab group, there were no statistically significant differences (p=0.83) in the rates of remission (66% vs 56%), response without remission (15.38% vs 25%) or failure (18% vs 18%) depending on the dose of thiopurines. With respect to ADA-levels, no differences were found in both groups (7.69 vs 8.23μg/mL; p=0.37). CONCLUSION In our experience, no statistically significant differences were found in either anti-TNF levels or clinical-biological response/remission rates based on doses of azathioprine.

Abstract
PURPOSE Infliximab (IFX) therapy in inflammatory bowel disease (IBD) is associated with loss of response in half the patients, due to complex pharmacokinetic and immunological factors. Dashboard's Bayesian algorithms use information from model and individual multivariate determinants of IFX concentration and can predict dose and dosing interval. AIM To compare measured IFX concentrations in our laboratory with values predicted by iDose dashboard system and report its efficacy in managing patients not responding to conventional dosing schedule. METHOD Clinical history, demographic details, and laboratory findings such as albumin and C-reactive protein (CRP) data of IBD patients (n = 30; median age 23 years (IQR: 14.25 - 33.5)) referred for IFX drug monitoring in our laboratory from November 2017 to November 2019 were entered in iDose software. The IFX concentration predicted by iDose based on this information was compared with that measured in our laboratory. In addition, a prospective dashboard-guided dosing was prescribed in 11 of these 30 patients not responding to conventional dosing and was followed to assess their clinical outcome. RESULT IFX monitoring in our 30 patients had shown therapeutic concentration in 12, supratherapeutic in 2 and subtherapeutic concentration in 16 patients. The iDose predicted concentration showed concordance in 21 of these 30 patients. Of 11 patients managed with iDose-assisted prospective dosing, 8 achieved clinical remission, 2 showed partial response, and one developed antibodies. CONCLUSION Retrospective data analysis showed concordance between laboratory measured and iDose-predicted IFX level in 70% of patients. iDose-assisted management achieved clinical remission and cost reduction.

Abstract
INTRODUCTION Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. This real-world study evaluated persistence, dose titration, health care resource utilization (HCRU) and associated costs, and medication use among CD patients treated with ustekinumab (UST) in several pooled US commercial database populations. METHODS CD patients aged ≥ 18 years with medical or pharmacy claims for UST were selected from pooled data from 3 large, national commercial databases. The first observed medical or pharmacy claim for UST was the index date. Patients were required to have had ≥ 1 medical claim with a CD diagnosis during the 12 months prior to the index date and continuous health plan enrollment for a minimum of 12 months prior to and 12 months after the index date. Comparisons of outcomes during the baseline and follow-up periods were conducted using inferential statistical tests. RESULTS A total of 214 eligible UST patients were selected. The majority (74.8%) were biologic experienced (mean age: 41 years), and 83.6% remained treatment persistent during the 12-month post-index period. Among discontinuers, 25.7% restarted UST, and 8.6% switched from UST in the 12-month observation period. The mean treatment duration was 329 days. Most patients (77%) used the recommended UST dose, as defined as being within a 20% dose variation from label (90 mg/8 weeks ± 20%), 17.9% experienced dose escalation, and 5.1% experienced dose reduction. Post-index immunomodulator and corticosteroid use reduced by 20% and 28%, respectively, as compared with pre-index use among CD patients using UST. Annual all-cause ER visits and inpatient stays decreased by 20.5% and 30.3%, respectively, with similar downward trends for annual CD-related HCRU. CONCLUSIONS The majority of CD patients prescribed UST were biologic experienced, and persistence was high over the 1-year follow-up. UST treatment initiation was associated with reductions in ER visits, inpatient stays, and steroid and other medication use.

Abstract
Background/Aims Infliximab (IFX) often loses its therapeutic effect in initial responders with inflammatory bowel disease (IBD) over time. Low serum IFX trough levels (TLs) are linked to poor clinical response and outcomes. Maintenance of optimal therapeutic IFX concentrations is important for sustaining response and achieving good clinical outcomes. Measurement of serum IFX TLs is helpful for determining a further proper therapeutic plan. However, adequate therapeutic IFX TLs in pediatric IBD is uncertain. We aimed to identify the cutoff values for IFX TLs associated with laboratory response to IFX maintenance therapy. Methods Patients with pediatric IBD who had received IFX infusions between December 2008 and March 2015 at Samsung Medical Center were retrospectively investigated. We analyzed 239 blood samples that were collected from 103 pediatric patients. We measured IFX TLs at induction (6 and 14 weeks) and during maintenance therapy (>22 weeks, 8 weeks interval) by fluid-phase radioimmunoassays. Results A significant association was found between the erythrocyte sedimentation rate (ESR) and IFX TLs during maintenance (correlation coefficient, -0.11; p=0.0005). A cutoff value of 18 mm/hr for ESR was used to define higher levels. Receiver operating characteristic analysis identified optimal cutoff values: IFX TL >1.58 µg/mL (sensitivity 82% and specificity 73%). Conclusions Cutoff values are considered a prerequisite for further investigating the clinical usefulness of measurements of IFX in patients maintained with IFX treatment.

Abstract
To characterize the pharmacokinetics (PK) and exposure-response (E-R) relationship of ustekinumab, an anti-interleukin-12/interleukin-23 (IL-12/IL-23) human monoclonal antibody, in the treatment of moderately to severely active ulcerative colitis (UC), population PK and E-R modeling analyses were conducted based on the data from the pivotal phase 3 induction and maintenance studies in UC patients. The observed serum concentration-time data of ustekinumab were adequately described by a 2-compartment linear PK model with first-order absorption and first-order elimination. Body weight, baseline serum albumin, sex, and antibodies to ustekinumab were the covariates to influence ustekinumab PK, but the magnitudes of the effects of these covariates were not considered clinically relevant, and dose adjustment was not warranted. Positive E-R relationships were demonstrated between ustekinumab exposure metrics and clinical endpoints (including clinical response, clinical remission, and endoscopic healing based on Mayo score) at induction week 8 and maintenance week 44, consistent with the effectiveness of ustekinumab in the induction and maintenance treatment of patients with UC. E-R modeling results suggest that ustekinumab ∼6 mg/kg intravenous induction and 90-mg subcutaneous every-8-week maintenance dose would produce greater efficacy than the 130 mg intravenous induction and the 90-mg subcutaneous every-12-week maintenance regimen, respectively. Our work provides a comprehensive evaluation of ustekinumab PK and E-R in a modeling framework to support ustekinumab dose recommendations in patients with UC.

Abstract
BACKGROUND Vedolizumab is a gut-selective antibody to α4 β7 integrin approved to treat moderate-to-severe Crohn's disease and ulcerative colitis in adults. Inflammatory bowel disease (IBD) and immunosuppressant use are associated with increased risk of malignancy. AIM To analyse the incidence of malignancy with vedolizumab treatment in the GEMINI long-term safety (LTS) study and post-marketing (PM) setting. METHODS Malignancy data from the LTS study (May 2009 to May 2018), and data from the vedolizumab Global Safety Database (20 May 2014 to 19 May 2018), were identified using Medical Dictionary for Regulatory Activities coding. The number of patients experiencing malignancies in the LTS study (excluding malignancies within 1 year following vedolizumab initiation) was indirectly standardised against the number expected, using age- and sex-specific rates in patients with IBD from Optum's Clinformatics™ Data Mart (CDM) database. RESULTS Among 1785 patients with ≥1 year of follow-up post-vedolizumab initiation in the LTS study (total 5670 patient-years), observed numbers of malignancies were similar to those expected compared with CDM data (31 vs 29; ratio of observed to expected events = 1.08; P = 0.71; 95% confidence intervals [CI] 0.73, 1.53). The most common malignancies were renal and bladder (6). PM, 293 patients reported 299 malignancies (including malignancies within 1 year following vedolizumab initiation), in approximately 208 050 patient-years of vedolizumab exposure. Lower gastrointestinal malignancies were most common (59). CONCLUSIONS The number of malignancies in the LTS study was similar to that expected from an IBD population with no statistically significant differences, although few confounders could be corrected for. Limitations of PM safety reporting require consideration; however, the number of malignancies with vedolizumab appeared low.

Abstract
Background To assess the cost and patient impact of using small bowel and colon video capsule endoscopy (SBC) for scheduled monitoring of Crohn’s disease (CD). Methods An individual-patient, decision-analytic model of the CD care pathway was developed given current practice and expert input. A literature review informed clinical endpoints with data from peer-reviewed literature. Four thousand simulated CD patients were extrapolated from summary patient data from the Project Sonar Database. Two monitoring scenarios were assessed in this population. The first scenario represented common monitoring practice (CMP) for CD (ileocolonoscopy plus imaging), while in the second scenario patients were converted to disease monitoring using SBC. The cost-effectiveness of using SBC was assessed over 20 years. The cost of switching 50% of patients to SBC was assessed over 5 years for a health-plan including 12,000 patients with CD. Uncertainty of results was assessed using probabilistic sensitivity analysis. Results All patient groups showed increased quality of life with SBC versus CMP, with the highest gain in active symptomatic patients. Over 20 years, SBC reduced costs ($313,367 versus $320,015), increased life expectancy (18.15 versus 17.9 years) and increased quality of life (8.7 versus 8.0 QALY), making it a cost-effective option. SBC was cost-effective in 71% of individuals and 78% of populations including 50 patients. A payer implementing SBC in 50% of patients over 5 years could expect a decreased cost of monitoring (–$469 mean per patient) and surgery (–$698), but increased costs for active treatments (+$717). The discounted mean annual cost of care using CMP was $22,681 per patient over 5 years. The annual savings were $1135 per SBC-patient. The total savings for the payer over 5 years were $36.5 million. Conclusion SBC is likely to be a cost-effective and cost-saving strategy for monitoring CD in the US.

Abstract
BACKGROUND therapeutic monitoring of anti-TNF drugs and anti-drug antibody levels are useful for clinical decision-making, via the rationalization and optimization of the use of anti-TNF treatments. The objective of the present study was to validate the model of Ternant et al., in a cohort of patients with inflammatory bowel diseases (IBD). This model was originally established for patients with rheumatoid arthritis and was used in this study to optimize the adalimumab (ADA) dose and predict ADA trough levels (ATL). METHODS this study used concentration data points from 30 IBD patients who received ADA treatment between 2014 and 2015. A goodness-of-fit of the model was determined by evaluating the relationship between the observed ATL values and population model-predicted values (PRED) or individual model-predicted values (IPRED). RESULTS a total of 51 ADA concentration points were analyzed. The bias of the model was 2.39 (95% CI, 1.63-3.15) for PRED and 0.63 (95% CI, 0.23-1.03) for IPRED. The precision was 3.57 (95% CI, 2.90-4.13) and 1.53 (95% CI, 1.22-1.80), respectively. CONCLUSIONS therapeutic drug monitoring involving ATL may allow the optimization of the treatment of IBD patients. The validation results of the phamacokinectic (PK) model for ADA in IBD patients are inadequate. However, additional studies will strengthen the bias and precision of the model.

Abstract
Objectives: Inflammatory bowel disease (IBD) is associated with a high economic burden to society due to its early onset and chronic character. Here, we set out to characterize healthcare resource utilization and associated costs in Crohn's disease (CD) and ulcerative colitis (UC) patients with infliximab treatment, the most widely used first-line biologic agent in Finland, in a real-world clinical setting. Methods: This was a retrospective, non-interventional single-center study. Infliximab was administered in routine care, and data were collected retrospectively from electronic health records. All adult anti-TNF naïve CD or UC patients whose infliximab treatment was initiated at the Hospital District of Southwest Finland between the years of 2014 and 2016 were included in the study. Each patient was followed-up for 12 months after the initiation of infliximab treatment. Results: A total of 155 patients were included (45 CD, 110 UC). Altogether, 60.0% (n = 27) of all CD patients and 43.6% (n = 48) of all UC patients persisted on infliximab therapy 12 months after treatment initiation. The total cost was similar for both CD and UC cohorts (CD, €10,243; UC, €10,770), infliximab treatment being the highest individual cost (60.3% of the total cost in CD; 53.4% in UC). The mean number of infliximab infusions during the 12-month follow-up was 7.0 for CD and 6.5 for UC patients. Conclusions: IBD causes a significant burden to the Finnish healthcare system. This study provides a detailed characterization of the cost landscape of IBD and contributes to optimizing treatment strategies and healthcare resource use in the biosimilar era.

Abstract
INTRODUCTION Medications in treating Crohn's disease (CD) have evolved over the last two decades, particularly with the use of biologic agents. There are, however, concerns about the safety and adverse events associated with these medications. The authors review the safety profile of immunosuppressive medications used in Crohn's disease in adult patients. AREAS COVERED The authors performed a literature search until October 2018 to examine safety data on thiopurines, methotrexate, anti-TNFα agents, vedolizumab and ustekinumab. The authors focused on 'trial' and 'real-world' data for the biologic agents. Safety in pregnancy and the elderly are also presented. EXPERT OPINION Available data in CD suggest that immunosuppressive medications are relatively safe, although there are concerns about an elevated risk of serious infections, skin cancer and lymphoma particularly with thiopurines and anti-TNFα agents. Data on vedolizumab and ustekinumab suggest these newer biologic agents are well tolerated; however, longer term data in CD are required to identify risks with extended use. Apart from methotrexate, there appear to be no adverse congenital outcomes with exposure of drugs during pregnancy.

[PMID: 30833984 PMCID: PMC6393825 DOI: 10.1177/1756284819828238] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Accepted: 12/19/2018] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND The loss of response to adalimumab (ADL) has been related to low serum concentrations at trough. Currently, most methods commercially available for the quantification of ADL are enzyme-linked immunosorbent assay (ELISA) based, with a turnaround time of approximately 8 h, delaying the target dosage adjustment to the subsequent infusion. In this study, we aimed to evaluate the performance of the newly available rapid-test ADL quantification assay by comparing it with three established ELISA methods, using spiked samples and a set of clinical samples. METHODS Spiked samples from control donors and 120 serum samples from inflammatory bowel disease (IBD) patients undergoing ADL therapy were quantified using lateral flow Quantum Blue® Adalimumab and, the ELISA formats from Immundiagnostik, R-Biopharm and an in-house assay. RESULTS The rapid-test assay had intraclass correlation coefficients of 0.590, 0.864 and 0.761 when comparing with the Immundiagnostik, R-Biopharm and in-house assays, respectively. For the five therapeutic windows, the accuracy was high: ADL rapid test compared with the Immundiagnostik (58-88%); R-Biopharm, 68-89%; and in house, 60-88%; and kappa statistics revealed 0.492-0.602, 0.531-0.659 and 0.545-0.682, respectively. CONCLUSIONS The Quantum Blue® Adalimumab assay can replace the commonly used ELISA-based ADL quantification kits and it is a reliable alternative to these methods. This rapid-test assay enables the quantitative determination of ADL serum trough level in only 15 min. The developed assay allows measurement of ADL over a wide range. Hence, it represents a valuable tool for the clinician to assess the ADL trough level.

Abstract
BACKGROUND Few studies have addressed recent trends in hospitalization costs for inflammatory bowel disease (IBD). OBJECTIVE We explored trends and described patient and hospital factors associated with hospitalization costs for IBD. METHODS Using data from the 2003-2014 National Inpatient Sample for adults aged ≥ 18 years, we estimated costs using multivariable linear models and assessed linear trends by time periods using piecewise linear regressions. RESULTS In 2014, there were an estimated 56,290 hospitalizations for Crohn's disease (CD), with a mean cost of US$11,345 and median cost of US$7592; and 33,585 hospitalizations for ulcerative colitis (UC), with a mean cost of US$13,412 and median cost of US$8873. Higher costs were observed among Hispanic [adjusted cost ratio (ACR) = 1.07; 95% confidence interval (CI) = 1.00-1.14; p = 0.04] or other non-Hispanic (ACR = 1.09; 95% CI = 1.02-1.17; p = 0.01) CD patients than for non-Hispanic White CD patients. For UC patients, higher costs were observed among men (ACR = 1.09; 95% CI = 1.05-1.13; p < 0.001) compared with women and among patients aged 35-44 years, 45-54 years, and 55-64 years compared with those aged 18-24 years. Among all patients, factors associated with higher costs included higher household income, more comorbidities, and hospitals that were government nonfederal versus private, were large versus small, and were located in the West versus Northeast regions. From 2003 to 2008, total costs increased annually by 3% for CD (1.03; 95% CI = 1.02-1.05; p < 0.001) and 4% for UC (1.04; 95% CI = 1.02-1.06; p < 0.001), but remained unchanged from 2008 to 2014. CONCLUSIONS The findings are important to identify IBD patients with higher hospitalization costs and to inform policy plans on hospital resource allocation.

Abstract
BACKGROUND Infliximab trough levels (IFX-TLs) and antibodies to infliximab (ATIs) have been suggested as useful markers for the optimization of treatment in inflammatory bowel disease (IBD). We aimed to estimate the patterns over time of IFX-TLs and ATIs in IBD patients on maintenance treatment with IFX. METHODS Two different measurements of IFX-TLs and ATIs were performed (ELISA; Eagle BioSciences) at a 10-month interval using serum samples of consecutive patients on maintenance treatment with IFX. Certain biomarkers [hemoglobin, erythrocyte sedimentation rate, C-reactive protein (CRP), platelets, albumin] measured at the same time as well as clinical disease activity and quality of life were assessed. RESULTS Among a total of 86 IBD patients under maintenance treatment with IFX, 64 [49 Crohn's disease, 15 ulcerative colitis (UC), 42 men, mean age 44.2±15.2 years, 41 in combination therapy with immunomodulator, six in intensified dose], with two available measurements of IFX-TLs and ATIs (A and B), were included in the study. The median levels of IF-TLs were 5.07 (interquartiles range: 1.60-12.73) μg/ml in measurement A and 4.68 (1.19-7.83) μg/ml in measurement B (P<0.0001). Patients whose dose was intensified after the first measurement showed an increase in their median IFX-TLs from 1.47 to 8.5 μg/ml, whereas patients with stable IFX dose showed a significant reduction in the median IFX-TLs from 5.65 to 3.8 μg/ml (P<0.0001). In the logistic regression analysis, the decrease in IFX-TL was correlated significantly and independently with the increase in CRP [odds ratio 5.2 (1.4-19.0), P=0.01]. CONCLUSION IBD patients on maintenance treatment with IFX show decreasing patterns of IFX-TLs over time associated with increasing patterns of CRP levels.

Abstract
Inflammatory bowel disease (IBD) is a term that refers to two main conditions: Crohn's disease and ulcerative colitis. It is a lifelong inflammatory disorder that affects the gastrointestinal tract. Managing IBD requires a multidisciplinary team approach, and specialist IBD nurses have an important role in this, providing education, support and advocacy to patients with IBD. This article provides an overview of the symptoms of Crohn's disease and ulcerative colitis, as well as the medical, nutritional and surgical management strategies that can be used. It discusses the nurse's role in management and the importance of using a multidisciplinary team approach to provide optimum patient care and support.

Abstract
The effect of insulin priming on Il-10 expression, regulation of inflammatory cytokines and participation of intra-cellular signalling events, primarily ERK1/2 and PI3K/Akt, has been investigated in high glucose (HG) and/or lipopolysaccharide (LPS)-induced murine macrophages. Our results demonstrate that congruent with sharp increase in ERK1/2 and CREB phosphorylation, insulin stimulation in vitro promotes significant increase in Il-10 expression in mouse peritoneal macrophage and RAW 264.7 cells, both positive for anti-IRβ. Pharmacological inhibition of MEK/MAPK, but not PI3K/Akt cascade, abrogates CREB phosphorylation and Il-10 synthesis indicating functional relevance of insulin action. Conversely, priming with PI3K inhibitor wortmannin prevents insulin attenuation of HG- and/or LPS-induced p38 MAPK and NF-κB activation, Tnf-α, Il-1β expression as well as NO production. Congruent with reduced Il-10 expression, MEK inhibition abrogates insulin action allowing significant increase in Tlr4 expression and LPS response indicating insulin-induced Il-10 might have pivotal influence in regulation of chronic as well as acute inflammatory response.

Abstract
BACKGROUND There is little information regarding the use of biologics in Inflammatory Bowel Disease (IBD) patients in Japan. The aim of this study was to determine the factors associated with the use of biologics in the treatment of Japanese patients with IBD. METHODS An online survey was conducted among Japanese patients with IBD (n = 1035). Socioeconomic as well as treatment related information was collected. Logistic regression was applied to analyze the determinants of biologic treatment. RESULTS Younger age (≤ 40 years vs. > 65 years; OR:0.24), time since diagnosis (< 2 years vs. < 15 years; OR: 4.16), surgical history (OR:1.98) and visiting university hospitals (university hospitals vs. clinics; OR: 0.47) were associated with biologic treatment for Japanese IBD patients. CONCLUSIONS Currently, biologics have been used in younger IBD patients which may give rise to the presence of an age bias in biologic treatment. Further studies are required to confirm these results and to define appropriate IBD patients who should be treated with biologic agent.

Abstract
The management of inflammatory bowel disease (IBD), a significant cause of morbidity in the United States (US), has been revolutionized over the last two decades by the introduction of biologic therapies. These include antitumor necrosis factor α (TNF-α) agents. Since 2016, five biosimilar TNF-α inhibitors have been approved by the US Food and Drug Administration (FDA) for use in the treatment of IBD. The FDA has published a series of guidance documents related to the evaluation, licensing, and approval of biosimilars. The aim of this review is to provide an overview of these FDA guidances and the issues associated with biosimilars in the US.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) mainly consists of Crohn's disease (CD) and ulcerative colitis (UC). About 10%-15% of patients with IBD cannot be firmly diagnosed with CD or UC; hence, they are initially diagnosed as inflammatory bowel disease unclassified (IBD-U). Having a firm diagnosis is clearly preferred to guide treatment choices, and better understanding of the nature of IBD-U is required. METHODS We performed an analysis of a subset of pediatric subjects from an inception IBD cohort of patients initially enrolled in a prospective multicenter study (the RISK study). Initial diagnosis and 2-year follow-up data from the subjects diagnosed with IBD-U were analyzed. An expert panel verified final diagnosis using predefined criteria as a guide. Serological and disease-relevant ileal and rectal tissue gene expression profiles were investigated. The use and the time to initiate anti-TNFα treatment was analyzed among the outcome groups. RESULTS A total of 1411 subjects were enrolled with initial diagnosis of IBD, and among them, 136 subjects were initially diagnosed as IBD-U at enrollment. And 26% were reclassified as UC and 14% as CD within 2 years of diagnosis, while 60% remained as IBD-U. Of those who were reclassified, there was a 2:1 ratio, UC (n = 35) to CD (n = 19). The molecular and serological features of IBD-U at the end of follow-up were very similar to UC and very different from CD. There was less likelihood of receiving anti-TNFα agents if the diagnosis was IBD-U compared with CD (P < 0.0001). CONCLUSIONS In our cohort, 60% of the IBD-U subjects remained as unclassified at 2 years; of those subsequently classified, a higher percentage followed a course more similar to UC. Most of the IBD-U subjects at diagnosis had serological and molecular signatures that are very similar to UC. Although the atypical presentations made the clinician to make an interim diagnosis of IBD-U, results of the molecular and serological factors performed at the time of diagnosis suggests that they were very similar to UC. However, long-term studies are needed to better understand the natural history and molecular characterization of pediatric onset IBD-U. 10.1093/ibd/izy136_video1Video 1.Video 1.

Abstract
The introduction of monoclonal antibodies (mAbs) to the treatment of inflammatory bowel disease (IBD) was an important medical milestone. MAbs have been demonstrated as safe and efficacious treatments of IBD. However, a large percentage of patients either fail to respond initially or lose response to therapy after a period of treatment. Although there are factors associated with poor treatment outcomes in IBD, one cause for treatment failure may be low mAb exposure. Consequently, gastroenterologists have begun using therapeutic drug monitoring (TDM) to guide dose adjustment. However, while beneficial, TDM does not provide sufficient information to effectively adjust doses. The pharmacokinetics (PK) and pharmacodynamics (PD) of mAbs are complex, with numerous factors impacting on mAb PK and PD. The concept of dashboard-guided dosing based on Bayesian PK models allows physicians to combine TDM with factors influencing mAb PK to individualize therapy more effectively. One issue with TDM has been the slow turnaround of assay results, either necessitating an additional clinic visit for a sample or reacting to TDM results at a subsequent, rather than the current, dose. New point-of-care (POC) assays for mAbs are being developed that would potentially allow physicians to determine drug concentration quickly. However, work remains to understand how to determine what target exposure is needed for an individual patient, and whether the combination of POC assays and dashboards presents a safe approach with substantial outcome benefit over the current standard of care.

Abstract
Biological therapies have revolutionized the treatment of several cancers and systemic immune-mediated inflammatory conditions. Expiry of patents protecting a number of biologics has provided the opportunity to commercialize highly similar versions, known as biosimilars. Biosimilars are approved by regulatory agencies via an independent pathway that requires extensive head-to-head comparison with the originator product. Biosimilars have the potential to provide savings to healthcare systems and expand patient access to biologics. In Latin American countries, regulatory frameworks for biosimilar approval have been introduced in recent years, and biosimilars of monoclonal antibody and fusion protein therapies are now emerging. However, the situation in this region is complicated by the presence of "non-comparable biotherapeutics" (also known as "intended copies"), which have not been rigorously compared with the originator product. We review the considerations for clinicians in Latin American countries, focusing on monoclonal antibody biosimilars relevant to oncology, rheumatology, gastroenterology, and dermatology.

Abstract
BACKGROUND Certolizumab pegol is an effective biologic for patients with Crohn's disease (CD). Individual differences in certolizumab pegol apparent clearance (CL/F) affect exposure and possibly efficacy. A previously developed population pharmacokinetic (PK) model did not account for dynamic changes in clinical parameters during therapy. OBJECTIVE The aim of this study was to refine the existing PK model to capture the time-varying influence of covariates. METHODS Data collected from 2157 Crohn's disease patients in nine studies were analyzed using nonlinear mixed-effects modeling software (NONMEM). Certolizumab pegol concentration-time data were described by a one-compartment PK model with first-order absorption, and one-compartment disposition with linear, time-dependent elimination using antidrug antibody (ADAb) concentration as a continuous variable. RESULTS The final dataset consisted of 12,926 analyzable records. Parameter estimates were absorption rate constant 1.83/day, CL/F 0.527 L/day, and apparent volume of distribution (V/F) 8.33 L. ADAb concentration (2.5-214 units/mL) increased the median CL/F by 142-174%. For a typical patient, body weight (46.8-100.5 kg) increased the median CL/F and V/F from 82 to 120%. Albumin (32-48 g/L) decreased and C-reactive protein (0.5-54.0 mg/L) increased the median CL/F from 123 to 85% and from 83 to 113%, respectively. Between-patient variability of CL/F was 19.6%. CONCLUSIONS By incorporating time-varying covariates, this population PK model reduces between-patient variability on CL/F estimates, and the relative influence of ADAb can now be assessed. As Crohn's disease patient covariates are often time-dependent, this model is more reflective of patient drug exposure with sustained treatment.

Abstract
Since the late 90s, biopharmaceuticals targeting tumor necrosis factor alpha have revolutionized the treatment of moderately to severely active inflammatory bowel disease. The robust efficacy witnessed in many patients stands in stark contrast with the observation of a proportion of patients who fail to respond or who lose response over time. Therapeutic drug monitoring has been proposed as a means to understand and respond to the variability in clinical response and remission. Various treatment algorithms have been proposed, but optimal use of these measurements in daily practice awaits additional prospective validation trials. This review provides an updated overview on the subject of therapeutic drug monitoring of biopharmaceuticals for the management of inflammatory bowel disease and how we could implement its concepts in a changing landscape.

Abstract
OBJECTIVES Current options for patients with steroid-dependent, chronic-active ulcerative colitis (UC) with insufficient response/intolerance to immunosuppressants (ISs) and/or biologics are limited. The aim of this study was to assess the long-term outcome of granulocyte/monocyte adsorptive (GMA) apheresis (Adacolumn®) in this population. MATERIALS AND METHODS Ninety five adults with steroid-dependent active UC and insufficient response/intolerance to IS and/or TNF inhibitors received 5-8 aphereses in a single induction series of ≤10 weeks. Endpoints included rates of remission (clinical activity index [CAI] ≤ 4) at weeks 24 and 48. RESULTS Of 94 patients (ITT population), remission and response rates were 34.0% and 44.7% at week 24, and 33.0% and 39.4% at week 48. Among 30 patients with prior failure of IS and biologics, 33.3% and 20.0% were in remission at weeks 24 and 48. At both weeks, 19.2% of patients achieved steroid-free remission. Sustained remission or response occurred in 27.7% of patients at 48 weeks. The cumulative colectomy rate at week 96 was 23.4%. Safety was consistent with previous findings. CONCLUSIONS This study confirms findings of the 12-week interim analysis and demonstrates that GMA apheresis provides a safe and beneficial long-term outcome for patients with chronic active UC resistant/intolerant to IS and/or TNF inhibitors.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract with a multifactorial pathophysiology. Full comprehension of IBD pathology is still out of reach and, therefore, treatment is far from ideal. Nevertheless, components involved in IBD pathogenesis including environmental, genetic, microbial, and immunological factors are continuously being investigated and the improved knowledge contributes to the development of new therapies. In this article we review the aspects of the immunopathogenesis of IBD, with focus on mucosal immunity, and discuss mechanisms of action for current and emerging biological therapies.

Abstract
BACKGROUND Approximately 15-20% of ulcerative colitis patients and 20-40% of those with Crohn's disease experience extraintestinal manifestations (EIMs) of their inflammatory bowel disease (IBD). Clinicians who treat IBD must manage EIMs affecting multiple organs that variably correlate with intestinal disease activity. Vedolizumab is a monoclonal antibody for the treatment of IBD with a gut-selective mechanism of action. AIMS This report evaluates whether vedolizumab is an effective treatment of EIMs, given its gut-specific mechanism of action. METHODS We report 8 case studies of patients with various EIMs, including pyoderma gangrenosum, peripheral arthralgia/arthritis, axial arthropathies, erythema nodosum, and uveitis, who received vedolizumab therapy. RESULTS Vedolizumab therapy was effective for pyoderma gangrenosum in ulcerative colitis, uveitis, erythema nodosum, polyarticular arthropathy, and ankylosing spondylitis/sacroiliitis but did not provide sustained benefit for the treatment of pyoderma gangrenosum in a patient with Crohn's disease. CONCLUSIONS These cases demonstrate the potential of vedolizumab as a treatment of EIMs in patients with IBD.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic disease placing a large health and economic burden on health systems worldwide. The treatment landscape is complex with multiple strategies to induce and maintain remission while avoiding long-term complications. The extent to which rising treatment costs, due to expensive biologic agents, are offset by improved outcomes and fewer hospitalisations and surgeries needs to be evaluated. This systematic review aimed to assess the cost-effectiveness of treatment strategies for IBD. MATERIALS AND METHODS A systematic literature search was performed in March 2017 to identify economic evaluations of pharmacological and surgical interventions, for adults diagnosed with Crohn's disease (CD) or ulcerative colitis (UC). Costs and incremental cost-effectiveness ratios (ICERs) were adjusted to reflect 2015 purchasing power parity (PPP). Risk of bias assessments and a narrative synthesis of individual study findings are presented. RESULTS Forty-nine articles were included; 24 on CD and 25 on UC. Infliximab and adalimumab induction and maintenance treatments were cost-effective compared to standard care in patients with moderate or severe CD; however, in patients with conventional-drug refractory CD, fistulising CD and for maintenance of surgically-induced remission ICERs were above acceptable cost-effectiveness thresholds. In mild UC, induction of remission using high dose mesalazine was dominant compared to standard dose. In UC refractory to conventional treatments, infliximab and adalimumab induction and maintenance treatment were not cost-effective compared to standard care; however, ICERs for treatment with vedolizumab and surgery were favourable. CONCLUSIONS We found that, in general, while biologic agents helped improve outcomes, they incurred high costs and therefore were not cost-effective, particularly for use as maintenance therapy. The cost-effectiveness of biologic agents may improve as market prices fall and with the introduction of biosimilars. Future research should identify optimal treatment strategies reflecting routine clinical practice, incorporate indirect costs and evaluate lifetime costs and benefits.

Abstract
OBJECTIVES A systematic review was conducted to explore the immunogenicity of biologic agents across inflammatory diseases and its potential impact on efficacy/safety. METHODS Literature searches were conducted through November 2016 to identify controlled and observational studies of biologics/biosimilars administered for treatment of rheumatoid arthritis (RA), psoriatic arthritis (PsA), juvenile idiopathic arthritis (JIA), ankylosing spondylitis (AS), non-radiographic axial spondyloarthritis (nr-axSpA), psoriasis (Ps), Crohn's disease, and ulcerative colitis. RESULTS Of >21,000 screened publications, 443 were included. Anti-drug antibody (ADAb) rates varied widely among biologics across diseases (and are not directly comparable because of immunoassay heterogeneity); the highest overall rates were reported with infliximab (0-83%), adalimumab (0-54%), and infliximab biosimilar CT-P13 (21-52%), and the lowest with secukinumab (0-1%), ustekinumab (1-11%), etanercept (0-13%), and golimumab (0-19%). Most ADAbs were neutralizing, except those to abatacept and etanercept. ADAb+ versus ADAb- patients had lower rates of clinical response to adalimumab (RA, PsA, JIA, AS, Ps), golimumab (RA), infliximab (RA, PsA, AS, Ps), rituximab (RA), ustekinumab (Ps), and CT-P13 (RA, AS). Higher rates of infusion-related reactions were reported in infliximab- and CT-P13-treated ADAb+ patients. Background immunosuppressives/anti-proliferatives reduced biologic immunogenicity across diseases. CONCLUSIONS Based on reviewed reports, biologic/biosimilar immunogenicity differs among agents, with the highest rates observed with infliximab and adalimumab. As ADAb formation in biologic-/biosimilar-treated patients may increase the risk of lost response, the immunogenicity of these agents is an important (albeit not the only) consideration in the treatment decision-making process.

Abstract
The use of temporary fecal diversion is of great importance to tenuous anastomosis, immunosuppressed patient, or actively infected patient. Its use protects newly constructed intestinal anastomoses from being the culprit of pelvic sepsis or systemic illness. Thus, potential morbidity and mortality can be averted. However, its appropriate or optimal use is often debated. We herein discuss the evidence for when to best use a diverting stoma for colorectal, coloanal, and ileoanal anastomoses. We also discuss the importance of considering a temporary diverting stoma in the setting of high-dose immunosuppression (e.g., transplant patients or inflammatory bowel disease), active infection, or upon creation of ileal pouch-anal anastomosis. Lastly, we discuss the advantages and disadvantages of a loop ileostomy versus colostomy for temporary diversion of fecal contents.

Abstract
Biologic therapy, such as those that target tumor necrosis factor (TNF) signaling, has proven to be an efficacious method of treatment for patients with inflammatory bowel disease (IBD) with regards to symptom management and mucosal healing. However, the rising prevalence of IBD worldwide and the ever-increasing burden of biologic pharmaceuticals in the health care industry is alarming for insurance companies, clinicians, and patients. The impending patent expiry and the relatively high costs of biologics, particularly anti-TNF agents, have paved the way for biosimilar development for IBD. The United States Food and Drug Administration defines a biosimilar as a biological product that is highly similar to its reference medicinal product, with no clinically meaningful differences in terms of safety, purity, and potency. The hope with biosimilars is that their entry into the market will be able to drive competition between pharmaceutical companies to reduce prices like that of the generic market, and that access to appropriate biologic treatments for IBD patients is increased in the long-term. Yet, there are challenging issues such as indication extrapolation and interchangeability that are still being debated in the field of IBD and must be addressed in future issued guidance. This review will discuss the issues and implications concerning the use of biosimilar therapy for IBD.

Abstract
INTRODUCTION Crohn's disease (CD) is a chronic, immune-mediated condition with a potentially disabling and destructive course. Despite growing data on when to use a therapeutic 'top-down' strategy, clinical management of this complex disorder is still challenging. Currently, the discussion of 'top-down' strategy in CD mostly includes biological therapy alone or in combination. Areas covered: This article is based on a review of existing literature regarding the use of biological therapy in a 'top-down' approach for the treatment of Crohn's disease. The authors reviewed all the major databases including MEDLINE as well as DDW and ECCO abstracts, respectively. Expert opinion: A 'top-down' therapeutic approach in Crohn's disease is strongly supported by existing data in patients with several risk factors for a severe course of disease. Moreover, there is an increasing amount of published data recommending a more individualised therapeutic strategy to identify candidates for 'top-down' treatment, based on enhanced diagnostics using biomarkers. Emerging therapeutic approaches besides existing therapy concepts using biologicals may possibly redefine the 'top-down' therapeutic strategy for Crohn's disease in the future.

Abstract
BACKGROUND & AIMS The efficacy and safety of vedolizumab, a humanized immunoglobulin G1 monoclonal antibody against the integrin α4β7, were demonstrated in multicenter, phase 3, randomized, placebo-controlled trials in patients with moderately to severely active ulcerative colitis (UC) or Crohn's disease. We analyzed data from 1 of these trials to determine the effects of vedolizumab therapy in patients with UC, based on past exposure to anti-tumor necrosis factor-α (TNF) antagonists. METHODS We performed a post hoc analysis of data from the GEMINI 1 study, collected from 464 patients who received vedolizumab or placebo but had not received a previous TNF antagonist (naive to TNF antagonists) and 367 patients with an inadequate response, loss of response, or intolerance to TNF antagonists (failure of TNF antagonists). Predefined outcomes of GEMINI 1 were evaluated in these subpopulations. RESULTS At Week 6, there were greater absolute differences in efficacy between vedolizumab and placebo in patients naive to TNF antagonists than patients with failure of TNF antagonists, although the risk ratios (RRs) for efficacy were similar for each group. Week 6 rates of response to vedolizumab and placebo were 53.1% and 26.3%, respectively, among patients naive to TNF antagonists (absolute difference, 26.4%; 95% confidence interval [CI], 12.4-40.4; RR, 2.0; 95% CI, 1.3-3.0); these rates were 39.0% and 20.6%, respectively, in patients with failure of TNF antagonists (absolute difference, 18.1%; 95% CI, 2.8-33.5; RR, 1.9; 95% CI, 1.1-3.2). During maintenance therapy, the absolute differences were similar but the RR for efficacy was higher for patients with failure of TNF antagonists than for patients naive to TNF antagonists, for most outcomes. Week 52 rates of remission with vedolizumab and placebo were 46.9% and 19.0%, respectively, in patients naive to TNF antagonists (absolute difference, 28.0%; 95% CI, 14.9-41.1; RR, 2.5; 95% CI, 1.5-4.0) and 36.1% and 5.3%, respectively, in patients with failure of TNF antagonists (absolute difference, 29.5%; 95% CI, 12.8-46.1; RR, 6.6; 95% CI, 1.7-26.5). No differences in adverse events were observed among groups. CONCLUSIONS Vedolizumab demonstrated significantly greater efficacy as induction and maintenance therapy for UC than placebo in patients naive to TNF antagonists and patients with TNF antagonist failure. There were numerically greater treatment differences at Week 6 among patients receiving vedolizumab who were naive to TNF antagonists than patients with TNF antagonist failure.

Abstract
BACKGROUND Patients with Crohn's disease in whom tumor necrosis factor antagonist therapy fails have limited treatment options, and the benefit of reintroducing the same therapy remains unclear. Here, we report results from PRECiSE 4 (NCT00160706), an open-label extension study of certolizumab pegol in patients who withdrew from the placebo-controlled studies PRECiSE 1 or 2. METHODS Patients eligible for PRECiSE 4 had Crohn's disease exacerbation on placebo or primary or secondary failure to certolizumab pegol in PRECiSE 1 or 2, and received 400 mg certolizumab pegol subcutaneously at weeks 0, 2, and 4 and every 4 weeks thereafter up to 360 weeks. We assessed safety (adverse events) and efficacy (clinical remission) of extended certolizumab pegol therapy. RESULTS Patients enrolled in PRECiSE 4 (N = 310; mean age, 37 yr; 58% female; 95% white) had a mean Crohn's disease duration of 8.5 years before entering the qualifying studies. At weeks 52, 104, and 156, remission rates were 28.5%, 17.5%, and 12.6% by nonremitter imputation, and 63.8%, 60.0%, and 63.5% by observed cases, with 47.4%, 31.9%, and 23.2% of patients, respectively, remaining on therapy. By study end (7.5 yr), 92.3% of patients discontinued therapy, 49% on account of adverse events. No new safety signals emerged. Incidence rate (new cases)/100 patient-years was 6.11 for serious infections and 1.29 for malignancies. CONCLUSIONS Certolizumab pegol was effective in many patients who previously discontinued certolizumab pegol for lack or loss of response. Thus, discontinuation of therapy may not always be necessary. Safety was consistent with previous findings.

Abstract
The goals of therapy in inflammatory bowel disease (IBD) are the induction and maintenance of clinical and biological remission. Mucosal healing is desirable to prevent complications and reduce the need for surgery, hospitalizations, and steroid exposure. Therapeutic monoclonal antibodies (biologic agents) have revolutionized the treatment of IBD. The initial magnitude of the clinical/biologic response to these agents has been associated with a number of underlying phenotypic features in the recipient. In addition, the durability of the initial response often declines over time. This can occur due to low drug serum drug levels, anti-drug antibodies, and a shift to alternative inflammatory pathways. This review discusses strategies that may optimize the initial response to biologics and sustain this to improve patient outcomes.

Oral immune therapy: targeting the systemic immune system via the gut immune system for the treatment of inflammatory bowel disease. Clin Transl Immunology 2016; 5:e60.

Abstract
Inflammatory bowel diseases (IBD) are associated with an altered systemic immune response leading to inflammation-mediated damage to the gut and other organs. Oral immune therapy is a method of systemic immune modulation via alteration of the gut immune system. It uses the inherit ability of the innate system of the gut to redirect the systemic innate and adaptive immune responses. Oral immune therapy is an attractive clinical approach to treat autoimmune and inflammatory disorders. It can induce immune modulation without immune suppression, has minimal toxicity and is easily administered. Targeting the systemic immune system via the gut immune system can serve as an attractive novel therapeutic method for IBD. This review summarizes the current data and discusses several examples of oral immune therapeutic methods for using the gut immune system to generate signals to reset systemic immunity as a treatment for IBD.

Abstract
Ascorbic acid (AA) has been shown to exert beneficial effects, including mitigating oxidative stress and inhibiting inflammation. However, the preventative effect of vitamin C in chronic inflammatory diseases such as inflammatory bowel disease (IBD) remains unclear. In our study, we investigated the anti-inflammatory effects of AA and possible mechanism involved in inhibiting dextran sulfate sodium (DSS)-induced ulcerative colitis in mice. Male C57BL/6 mice were randomly divided to three groups: control group, DSS group, and DSS plus ascorbic acid treated group. Several clinical and inflammatory parameters as well as oxidative stress were evaluated. The results demonstrated that ascorbic acid significantly reduced clinical signs, inflammatory cytokines, myeloperoxidase (MPO) and malonaldehyde (MDA) activities, whereas the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) were increased in DSS-induced mice. In addition, ascorbic acid was capable of inhibiting NF-κB, COX-2 and iNOS expression in the colonic. Taken together, these findings suggest that ascorbic acid contributes to the reduction of oxidative stress and inflammatory response in DSS-induced colitis and exerts the potential to prevent and clinical treatment of inflammatory bowel disease.
