Abstract
Value-based care focuses on improving the quality, effectiveness, and efficiency of health care while controlling costs. Low-value care implies services or interventions that provide little or no benefit to patients, have the potential to cause harm, incur unnecessary cost to patients, or waste limited health care resources. In this review, we discuss common instances of low-value care along the spectrum of management in inflammatory bowel diseases (IBD). These include low value care in: (1) diagnosis and monitoring of IBD: utilization of serological markers to screen and diagnose IBD, over-reliance on symptoms for monitoring disease, failure to employ treat-to-target strategies in symptomatic patients with IBD, and annual surveillance colonoscopies in patients at low risk of developing dysplasia; (2) treatment of IBD: use of 5-aminosalicylates in Crohn's disease, continuation of 5-aminosalicylates after escalation to immunosuppressive therapy, chronic corticosteroid use without steroid-sparing strategies, step therapy for Crohn's disease, failure to optimize tumor necrosis factor antagonists in patients with active disease and subsequently de-intensification of therapies in those who have achieved stable remission; and (3) management of hospitalized patients with IBD: routine cross-sectional imaging for patients with IBD presenting to the emergency department, withholding pharmacological prophylaxis for venous thromboembolism in patients hospitalized with IBD flare, and prolonged use of high-dose intravenous corticosteroids in patients with acute severe ulcerative colitis. This review is meant to bring attention to value-based care in IBD and provide guidance to treating practitioners. Future studies on systematic evaluation of high- and low-value care in patients with IBD are warranted.

Abstract
OBJECTIVE Ustekinumab was recently approved for the treatment of moderate-to-severe ulcerative colitis (UC). Although data from the UNIFI clinical trial are encouraging, real-world data assessing effectiveness and safety are scarce. The aim of this study was to assess the effectiveness, safety and pharmacokinetics of ustekinumab in a large cohort of refractory UC patients. METHODS Multicenter observational study of UC patients who received ustekinumab for active disease. The Partial Mayo Score (PMS), endoscopic activity, C-reactive protein (CRP) and faecal calprotectin (FC) were recorded at baseline and at different time points. Demographic and clinical data, adverse events (AEs) and surgeries were documented. RESULTS A total of 108 patients were analyzed from 4 referral Spanish hospitals. The clinical remission rates were 59%, 56.5%, 57% and 69% of patients at weeks 8, 16, 24 and 52, respectively. Normalization of FC was achieved in 39.6%, 41% and 51% at weeks 8, 24 and 52, respectively. CRP normalization was observed in 79%, 75% and 76.5% of patients at weeks 8, 24 and 52, respectively. Fewer previous anti-TNF agents and loss of response to anti-TNF were associated with clinical response and normalization of FC, respectively. AEs were observed in 5 patients, and 9 underwent colectomy. Ustekinumab persistence rates were 91%, 83% and 81% at 24, 48 and 96 weeks, respectively. CONCLUSIONS Ustekinumab demonstrated, in the real-world setting, long-term effectiveness and a favorable safety profile in a cohort of refractory UC patients.

Early recapture of response with tofacitinib 10 mg twice daily in patients with ulcerative colitis in OCTAVE Open following dose reduction or treatment interruption in OCTAVE Sustain. J Gastroenterol Hepatol 2024; 39:264-271. [PMID: 37953548 DOI: 10.1111/jgh.16386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 09/21/2023] [Accepted: 10/10/2023] [Indexed: 11/14/2023]
Abstract
BACKGROUND AND AIM Tofacitinib is an oral Janus kinase inhibitor for the treatment of ulcerative colitis. These post hoc analyses evaluated early improvement in patient-reported outcomes with tofacitinib 10 mg twice daily (BID) in OCTAVE Open among patients with ulcerative colitis who experienced treatment failure with placebo (retreatment subpopulation) or tofacitinib 5 mg BID (dose escalation subpopulation) during maintenance. METHODS Endpoints based on Mayo subscores (rectal bleeding improvement, stool frequency improvement, and symptomatic [both rectal bleeding and stool frequency] improvement) were analyzed overall and by prior tumor necrosis factor inhibitor (TNFi) failure status from month (M)1-M6 in OCTAVE Open. Changes from baseline in partial Mayo score, rectal bleeding subscore, and stool frequency subscore at M1 were also analyzed, by M2 clinical response status. RESULTS At M1 of OCTAVE Open, 83.2%, 70.3%, and 64.4% of patients in the retreatment subpopulation (n = 101) had rectal bleeding improvement, stool frequency improvement, and symptomatic improvement, respectively. Corresponding values in the dose escalation subpopulation (n = 57) were 59.6%, 50.9%, and 38.6%. For both subpopulations, results were generally consistent regardless of prior TNFi failure. In the dose escalation subpopulation, mean decrease from baseline in partial Mayo score and stool frequency subscore at M1 was greater in patients with versus without a clinical response at M2. CONCLUSIONS Rectal bleeding improvement and stool frequency improvement were achieved by M1 in many patients receiving tofacitinib 10 mg BID in both subpopulations, with no apparent difference by prior TNFi failure. Analyses were limited by small sample sizes for some subgroups.

Using Computer Vision to Improve Endoscopic Disease Quantification in Therapeutic Clinical Trials of Ulcerative Colitis. Gastroenterology 2024; 166:155-167.e2.

Abstract
BACKGROUND & AIMS Endoscopic assessment of ulcerative colitis (UC) typically reports only the maximum severity observed. Computer vision methods may better quantify mucosal injury detail, which varies among patients. METHODS Endoscopic video from the UNIFI clinical trial (A Study to Evaluate the Safety and Efficacy of Ustekinumab Induction and Maintenance Therapy in Participants With Moderately to Severely Active Ulcerative Colitis) comparing ustekinumab and placebo for UC were processed in a computer vision analysis that spatially mapped Mayo Endoscopic Score (MES) to generate the Cumulative Disease Score (CDS). CDS was compared with the MES for differentiating ustekinumab vs placebo treatment response and agreement with symptomatic remission at week 44. Statistical power, effect, and estimated sample sizes for detecting endoscopic differences between treatments were calculated using both CDS and MES measures. Endoscopic video from a separate phase 2 clinical trial replication cohort was performed for validation of CDS performance. RESULTS Among 748 induction and 348 maintenance patients, CDS was lower in ustekinumab vs placebo users at week 8 (141.9 vs 184.3; P < .0001) and week 44 (78.2 vs 151.5; P < .0001). CDS was correlated with the MES (P < .0001) and all clinical components of the partial Mayo score (P < .0001). Stratification by pretreatment CDS revealed ustekinumab was more effective than placebo (P < .0001) with increasing effect in severe vs mild disease (-85.0 vs -55.4; P < .0001). Compared with the MES, CDS was more sensitive to change, requiring 50% fewer participants to demonstrate endoscopic differences between ustekinumab and placebo (Hedges' g = 0.743 vs 0.460). CDS performance in the JAK-UC replication cohort was similar to UNIFI. CONCLUSIONS As an automated and quantitative measure of global endoscopic disease severity, the CDS offers artificial intelligence enhancement of traditional MES capability to better evaluate UC in clinical trials and potentially practice.

Abstract
BACKGROUND & AIMS Biomarkers are used frequently for evaluation and monitoring of patients with Crohn's disease (CD). This American Gastroenterological Association (AGA) guideline is intended to support practitioners in decisions about the use of biomarkers for the management of CD. METHODS A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation framework to formulate patient-centered clinical questions and review evidence on the performance of fecal calprotectin, serum C-reactive protein (CRP), and Endoscopic Healing Index in patients with established CD who were asymptomatic, had symptoms of varying severity, or were in surgically induced remission. Biomarker performance was assessed against the gold standard of endoscopic activity, defined as a Simple Endoscopic Score for Crohn's Disease ≥3. The panel used the Grading of Recommendations Assessment, Development and Evaluation Evidence-to-Decision framework to develop recommendations for use of biomarkers in various settings. Implementation considerations were formulated for each recommendation to inform clinical practice. RESULTS The guideline panel made 11 conditional recommendations. In patients with CD in symptomatic remission, the panel suggests use of a biomarker- and symptom-based monitoring strategy over symptoms alone. In patients in symptomatic remission, a fecal calprotectin <150 μg/g and normal CRP rules out active inflammation, avoiding endoscopic evaluation for assessment of disease activity. However, elevated biomarkers in this setting merit confirmation with endoscopy before treatment adjustment. In patients with CD with mild symptoms, neither normal nor elevated biomarkers alone are sufficiently accurate to determine endoscopic activity. In patients with CD with moderate to severe symptoms, elevated fecal calprotectin or serum CRP suggests endoscopic activity, precluding routine endoscopic assessment for disease activity. In patients with CD in surgically induced remission in low-risk patients on pharmacologic prophylaxis, a normal fecal calprotectin reliably rules out endoscopic recurrence. In other postoperative settings, the panel suggests endoscopic assessment for establishing postoperative recurrence. CONCLUSIONS In patients with CD, fecal calprotectin and serum CRP can inform disease management in both asymptomatic and symptomatic disease. Discordance between symptom assessment and biomarker value may merit endoscopic evaluation for confirmation of status of disease activity.

Clin Transl Sci 2023; 16:2310-2322. [PMID: 37718498 PMCID: PMC10651636 DOI: 10.1111/cts.13632] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 08/16/2023] [Accepted: 08/21/2023] [Indexed: 09/19/2023] Open
Abstract
The Mayo Clinical Score is used in clinical trials to describe the clinical status of patients with ulcerative colitis (UC). It comprises four subscores: rectal bleeding (RB), stool frequency (SF), physician's global assessment, and endoscopy (ENDO). According to recent US Food and Drug Administration guidelines (Ulcerative colitis: developing drugs for treatment, Guidance Document, https://www.fda.gov/regulatory-information/s. 2022), clinical response and remission should be based on modified Mayo Score (mMS) relying on RB, SF, and ENDO. Typically, ENDO is performed at the beginning and end of each phase, whereas RB and SF are more frequently available. Item response theory (IRT) models allow the shared information to be used for prediction of all subscores at each observation time; therefore, it leverages information from RB and SF to predict ENDO. A UC disease IRT model was developed based on four etrolizumab phase III studies to describe the longitudinal mMS subscores, placebo response, and remission at the end of induction and maintenance. For each subscore, a bounded integer model was developed. The placebo response was characterized by a mono-exponential function acting on all mMS subscores similarly. The final model reliably predicted longitudinal mMS data. In addition, remission was well-predicted by the model, with only 5% overprediction at the end of induction and 3% underprediction at the end of maintenance. External evaluation of the final model using placebo arms from five different studies indicated adequate performance for both longitudinal mMS subscores and remission status. These results suggest utility of the current disease model for informed decision making in UC clinical development, such as assisting future clinical trial designs and evaluations.

Abstract
A suitable, non-invasive biomarker for assessing endoscopic disease activity (EDA) in ulcerative colitis (UC) has yet to be identified. Our study aimed to develop a cost-effective and non-invasive machine learning (ML) method that utilizes the cost-free Inflammatory Bowel Disease Questionnaire (IBDQ) score and low-cost biological predictors to estimate EDA. Four random forest (RF) and four multilayer perceptron (MLP) classifiers were proposed. The results show that the inclusion of IBDQ in the list of predictors that were fed to the models improved accuracy and the AUC for both the RF and the MLP algorithms. Moreover, the RF technique performed noticeably better than the MLP method on unseen data (the independent patient cohort). This is the first study to propose the use of IBDQ as a predictor in an ML model to estimate UC EDA. The deployment of this ML model can furnish doctors and patients with valuable insights into EDA, a highly beneficial resource for individuals with UC who need long-term treatment.

Abstract
BACKGROUND Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). The tofacitinib OCTAVE clinical program included phase III induction (OCTAVE Induction 1 and 2) and maintenance (OCTAVE Sustain) studies, and an open-label, long-term extension study (OCTAVE Open). OBJECTIVE This post hoc analysis assessed selected long-term, disease-specific patient-reported outcome (PRO) and health-related quality-of-life (HRQoL) measurements in patients with UC receiving tofacitinib in the OCTAVE clinical program. METHODS Analyses included patients from OCTAVE Open assigned to tofacitinib 5 mg twice daily (subpopulation in remission at Week 52 of OCTAVE Sustain). OCTAVE Open data from the final analyses are shown to Month 48. Endpoints included rectal bleeding subscore (RBS) = 0, stool frequency subscore (SFS) ≤ 1, and HRQoL measure, Inflammatory Bowel Disease Questionnaire (IBDQ) remission (IBDQ total score ≥ 170); with non-responder imputation for missing data at all visits, and last observation carried forward for visits after a patient advanced to the next study (NRI-LOCF). Observed cases were also assessed. RESULTS At Month 48, of 175 patients, 95 (54.3%) and 96 (54.9%) achieved/maintained RBS = 0 and SFS ≤ 1, respectively (NRI-LOCF). Additionally, 93 (53.1%) patients achieved/maintained IBDQ remission at Month 48 (NRI-LOCF). CONCLUSIONS Among patients who entered OCTAVE Open in remission, most maintained normalization of rectal bleeding and improvement in stool frequency for ≤ 4 years of follow-up in OCTAVE Open. IBDQ remission was also generally maintained in OCTAVE Open. These data show robust maintenance of key UC PROs and durability of response with tofacitinib 5 mg twice daily.

Abstract
BACKGROUND & AIMS Biomarkers are used frequently for noninvasive monitoring and treatment decision making in the management of patients with ulcerative colitis (UC). This American Gastroenterological Association (AGA) guideline is intended to support practitioners in decisions about the use of biomarkers for the management of UC. METHODS A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation framework to prioritize clinical questions, identify patient-centered outcomes, and conduct an evidence synthesis on the clinical performance of serum C-reactive protein (CRP), fecal calprotectin, and fecal lactoferrin as biomarkers of disease activity in patients with established UC in symptomatic remission or with active symptoms. The guideline panel used the Evidence-to-Decision framework to develop recommendations for the use of biomarkers for monitoring and management of UC and provided implementation considerations for clinical practice. RESULTS The guideline panel made 7 conditional recommendations. In patients with UC in symptomatic remission, the panel suggests the use of a biomarker- and symptom-based monitoring strategy over a symptom-based monitoring strategy. For patients in symptomatic remission, the panel suggests using fecal calprotectin <150 μg/g, normal fecal lactoferrin, and/or normal CRP to rule out active inflammation and avoid routine endoscopic assessment of disease. In patients with UC with moderate to severe symptoms, the panel suggests using fecal calprotectin >150 μg/g, elevated fecal lactoferrin, or elevated CRP to inform treatment decisions and avoid routine endoscopic assessment of disease. However, in patients in symptomatic remission but elevated biomarkers, and in patients with moderate to severe symptoms with normal biomarkers, the panel suggests endoscopic assessment of disease to inform treatment decisions. In patients with UC with mild symptoms, the panel suggests endoscopic assessment of disease activity to inform treatment decisions. The panel identified the use of a biomarker-based monitoring strategy over an endoscopy-based monitoring strategy as a knowledge gap. The panel also proposed key implementation considerations for optimal use of biomarkers, and identified areas for future research. CONCLUSIONS In patients with UC, noninvasive biomarkers, including fecal calprotectin, fecal lactoferrin, and serum CRP can inform disease monitoring and management.

Abstract
BACKGROUND Patient-reported outcomes (PROs) are increasingly emphasized as endpoints in clinical trials of ulcerative colitis (UC). However, the prognostic value of early improvement in PROs for long-term outcomes remains unclear. METHODS This was a post-hoc analysis of 611 vedolizumab-treated or adalimumab-treated patients in the VARSITY trial (Clinicaltrial.gov: NCT02497469). Stool frequency (SF) and rectal bleeding score (RBS) as reported in the Mayo score at post-induction (week 6 and 14) was assessed for their association with one-year endoscopic improvement (EI), defined as Mayo endoscopic subscore <2; histo-endoscopic mucosal improvement (HEMI), defined as EI and Geboes highest grade <3.2, clinical remission (CR), defined as total Mayo score ≤2; and PRO-2 remission, defined as RBS of 0 and SF ≤1. Multivariable logistic regression models adjusted for confounders assessed the relationships between post-induction PROs and outcomes of interest at one-year. RESULTS Patients with severe SF at week 6 were significantly less likely to achieve one-year EI compared to those with non-severe SF [aOR 0.40 (95% CI: 0.24-0.68), p < .001]. Absence of rectal bleeding at week 6 was associated with greater odds of achieving EI at one-year [aOR 2.21 (95% CI: 1.58-3.09), p < .001]. These findings were consistent across comparisons at week 14. Similar findings were observed for the outcomes of one-year HEMI, CR and PRO-2 remission. No difference was observed between the modified partial Mayo score and modified PRO-2 score. CONCLUSIONS Post-induction PROs strongly predict the odds of CR and EI in UC and simplified evaluations can be used to assess early response to UC therapies.

Rapid and Sustained Symptom Relief in Patients With Ulcerative Colitis Treated With Filgotinib: Data From the Phase 2b/3 SELECTION Trial. Am J Gastroenterol 2023; 118:138-147. [PMID: 36113491 PMCID: PMC9810009 DOI: 10.14309/ajg.0000000000001979] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Accepted: 08/01/2022] [Indexed: 02/04/2023]
Abstract
INTRODUCTION Patients with ulcerative colitis (UC) regard rapid onset of action among the most important aspects of their treatment. We used the partial Mayo Clinic Score (pMCS) and component patient-reported subscores to assess the rapidity and sustainability of response to filgotinib, a once-daily, oral Janus kinase 1 preferential inhibitor, in adults with moderately to severely active UC in the phase 2b/3 SELECTION trial. The association between early symptomatic improvements and health-related quality of life (HRQoL) outcomes was also assessed. METHODS In these post hoc analyses of the double-blinded, randomized, placebo-controlled 58-week SELECTION trial (NCT02914522), rectal bleeding and stool frequency diary data on days 1-15 and pMCS remission and response at multiple time points including weeks 10 and 58 were evaluated. HRQoL was assessed using the Inflammatory Bowel Disease Questionnaire at weeks 10 and 58. RESULTS Filgotinib 200 mg relative to placebo improved rectal bleeding and stool frequency within 7 days ( P < 0.05). By week 2, greater proportions of filgotinib 200 mg-treated patients than placebo-treated patients achieved pMCS remission (biologic-naive, 15.1% vs 8.0%, P = 0.0410; biologic-experienced, 10.3% vs 4.2%, P = 0.0274). A similar treatment effect was observed at week 58 ( P < 0.0001). Day 7 rectal bleeding and stool frequency subscores were associated with the Mayo Clinic Score response at weeks 10 and 58. Patients in pMCS remission at weeks 10 and 58 had greater improvements in the Inflammatory Bowel Disease Questionnaire score than those not in pMCS remission. DISCUSSION Filgotinib 200 mg daily resulted in rapid and sustained improvements in both UC symptoms and HRQoL.

Abstract
BACKGROUND & AIMS Comparative effectiveness studies are needed to help position therapies for ulcerative colitis (UC). We compared the efficacy of infliximab vs vedolizumab for moderate to severe biologic-naïve UC using patient-level data from clinical trial program data sets. METHODS This was a post hoc analysis of 3 UC clinical trial programs that included data on 795 biologic-naïve UC patients. Differences in proportions of patients achieving week 6 clinical remission (CR) and response, and 1-year CR, corticosteroid-free CR, and endoscopic remission (ER), are reported. Multivariate logistic regression was used to adjust for potential confounders. As a sensitivity analysis, propensity scores were calculated and a cohort of matched participants with similar distribution of baseline covariates was created. All analyses were intention-to-treat. RESULTS At week 6, comparable proportions of patients achieved clinical response and CR with infliximab vs vedolizumab (clinical response, 60.5% [138 of 228] vs 60.0% [340 of 567]; P = .884; and CR, 39.9% [91 of 228] vs 38.6% [219 of 567]; P = .736). Similar proportions of patients achieved 1-year CR with infliximab vs vedolizumab (39.9% [91 of 228] vs 38.6% [219 of 567]; adjusted odds ratio [aOR], 1.02; 95% CI, 0.74-1.40). Infliximab-treated patients had significantly higher rates of 1-year ER (36.0% [82 of 228] vs 25.6% [145 of 567]; aOR, 1.60; 95% CI, 1.12-2.28) and corticosteroid-free CR (29.5% [23 of 78] vs 15.0% [38 of 254]; aOR, 2.36; 95% CI, 1.27-4.39). Similar results were observed in the propensity score matched cohort. CONCLUSIONS Although infliximab and vedolizumab have similar efficacy in clinical symptom improvement, infliximab had higher rates of 1-year corticosteroid-free CR and ER in treatment of biologic-naïve UC.

Abstract
Inflammatory bowel disease (IBD) is a chronic immune-mediated inflammation of the gastrointestinal tract with a highly heterogeneous presentation. It has a relapsing and remitting clinical course that necessitates lifelong monitoring and treatment. Although the availability of a variety of effective therapeutic options including immunomodulators and biologics (such as TNF, CAM inhibitors) has led to a paradigm shift in the treatment outcomes and clinical management of IBD patients, some patients still either fail to respond or lose their responsiveness to therapy over time. Therefore, according to the recent Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE-II) recommendations, continuous disease monitoring from symptomatic relief to endoscopic healing along with short- and long-term therapeutic responses are critical for providing IBD patients with a tailored therapy algorithm. Moreover, considering the high unmet need for novel therapeutic approaches for IBD patients, various new modulators of cytokine signaling events (for example, JAK/TYK inhibitors), inhibitors of cytokines (for example IL-12/IL-23, IL-22, IL-36, and IL-6 inhibitors), anti-adhesion and migration strategies (for example, β7 integrin, sphingosine 1-phosphate receptors, and stem cells), as well as microbial-based therapeutics to decolonize the bed buds (for example, fecal microbiota transplantation and bacterial inhibitors) are currently being evaluated in different phases of controlled clinical trials. This review aims to offer a comprehensive overview of available treatment options and emerging therapeutic approaches for IBD patients. Furthermore, predictive biomarkers for monitoring the therapeutic response to different IBD therapies are also discussed.

Abstract
Twenty-five years ago the field was revolutionized by the introduction of infliximab as the first hybrid anti-TNF-antibody. Subsequently, other humanized anti-TNFs were developed and marketed, followed by antibodies to new targets including integrins (vedolizumab) and interleukin 12/23 (ustekinumab). All these so-called biologicals were shown in registrational trials to induce remission superior to placebo but consistently were effective in only a minority of patients. Even though in most trials only the responders were selected to continue on the respective medication for maintenance, many experienced a secondary loss of response and only a minority of usually <25% of the initial cohort achieved long-term (1 year) remission. In 'real life studies', the outcome was somewhat better, probably due to proper selection of patients and open, mostly retrospective study designs. A clear benefit of biologicals is apparent in otherwise treatment refractory patients, in extraintestinal manifestations and in Crohn´s disease (CD) with fistulizing complications. Biologicals achieve mucosal healing (MH) more often than corticosteroids or thiopurines, and MH is associated with improved prognosis. However, this does not justify escalating treatment until MH is reached since controlled trials proving this point of 'treat to target' are lacking both in ulcerative colitis and CD. Surgical rates have decreased with increasing use of biologicals, but disease progression has not been proven to improve. With the exception of opportunistic infections, serious adverse events are rare. In conclusion, biologicals have changed the scene considerably and expanded our armamentarium, but there is also a marketing hype fostering expectations without evidence.

A Microsimulation Model to Determine the Cost-Effectiveness of Treat-to-Target Strategies for Crohn's Disease. Am J Gastroenterol 2021; 116:1709-1719.

Abstract
INTRODUCTION Cost-effectiveness of biomarker- vs endoscopy-based treat-to-target monitoring in Crohn's disease (CD) is unknown. METHODS A microsimulation model for CD was built to simulate biomarker (fecal calprotectin) vs endoscopy-based monitoring in a treat-to-target fashion. Published literature in combination with patient-level data from phase 3 clinical trials and population estimates for therapeutic drug monitoring were used to generate transition probabilities, costs, and utilities. Tracker variables were used to modify downstream probabilities and outcomes based on previous exposures, response patterns, and disease-related complications or surgery history. The primary outcome was cost-effectiveness over a 5-year horizon at a willingness-to-pay threshold of $100,000/quality-adjusted life-year. Probabilistic sensitivity analyses in addition to multiple 1-, 2-, and 3-way microsimulation sensitivity analyses were performed. RESULTS In the base-case model, the endoscopy-based monitoring strategy dominated the biomarker-based monitoring strategy over a 5-year horizon. Over shorter periods of observation, the biomarker-based monitoring strategy became progressively more cost-effective, with cost-effectiveness achieved for this strategy over a 1-year horizon. Therapeutic drug monitoring did not influence short-term cost-effectiveness of biomarker-based monitoring. Once in endoscopic remission, continued biomarker-based vs endoscopy-based monitoring was more cost-effective. A hybrid biomarker-endoscopy-based monitoring strategy dominated the endoscopy-based monitoring strategy over a 5-year horizon. The strongest determinants for cost-effectiveness were cost of colonoscopy and diagnostic performance of fecal calprotectin. DISCUSSION The most cost-effective approach for treat-to-target monitoring in CD is up-front biomarker-based monitoring followed by endoscopy-based monitoring if not in endoscopic remission by 1 year and then returning to biomarker-based monitoring once in endoscopic remission.

Abstract
BACKGROUND & AIMS Little is known about the cost effectiveness of endoscopy or biomarker-based treat to target monitoring of patients with ulcerative colitis (UC). METHODS We used a microsimulation model to identify the most cost effective treat to target monitoring strategy for patients with UC staring therapy with biologics or small molecule inhibitors. We assessed symptoms (rectal bleeding) alone, a combination of symptoms and a biomarker (fecal calprotectin), and endoscopy. Transition probabilities, costs, and quality-adjusted life year (QALY) estimates were derived from published estimates. The microsimulation model tracked an individual patient's disease course and treatment exposures to modify downstream treatment effectiveness, probabilities, and disease outcomes. The primary analysis included 100,000 individuals over 5 years with a willingness to pay threshold of $100,000/QALY. Probabilistic sensitivity analyses were performed with 500 samples and 250 trials, in addition to multiple 1-, 2-, and 3-way microsimulation sensitivity analyses. RESULTS A total of 32 treatment sequencing algorithms were modeled alongside 3 disease monitoring strategies within a treat to target approach for UC. Combination symptom and biomarker-based monitoring resulted in the highest QALY estimate among all the treatment sequencing algorithms. However, monitoring disease activity with symptoms alone was the most cost-effective strategy in 86% of scenarios, followed by combination symptom and biomarker monitoring in 9%, and endoscopy monitoring in 5%. Results were sensitive to treatment costs, patient willingness to consider colectomy as a treatment option, and endoscopy costs. Endoscopy-based monitoring was favored when treatment costs were high and patients were unwilling to undergo colectomy. CONCLUSIONS The combination symptom and biomarker-based monitoring resulted in the highest QALY estimate. However, symptom-based monitoring is the most cost-effective approach to implementing treat to target monitoring for patients with UC receiving biologics and small molecule inhibitors.

Abstract
AIMS Controversies regarding infliximab treatment in elderly patients with inflammatory bowel diseases remain. We evaluated the effect of patient's age on infliximab exposure, efficacy and safety. METHODS Retrospective case-control data of patients receiving infliximab induction treatment were analysed. A population pharmacokinetic model was developed to estimate individual pharmacokinetic parameters. A logistic regression model was used to investigate the effect of exposure on endoscopic remission. Repeated time-to-event models were developed to describe the hazard of safety events over time. RESULTS A total of 104 patients (46 elderly, ≥65 years) were included. A two-compartment population pharmacokinetic model with linear elimination adequately described the data. Infliximab clearance decreased with older age, higher serum albumin, lower fat-free mass, lower C-reactive protein and absence of immunogenicity. Yet, infliximab exposure was not significantly different between elderly and nonelderly. Regardless of age, an infliximab trough concentration at week (w)14 of 15.6 mg/L was associated with a 50% probability of attaining endoscopic remission between w6 and w22. Infliximab exposure during induction treatment was not a risk factor of (severe) adverse events. The hazard of severe adverse events and malignancy increased by 2% and 7%, respectively, with increasing year of age. Concomitant immunomodulator use increased the hazard of infection by 958%, regardless of age. CONCLUSIONS Elderly patients attained infliximab exposure and endoscopic remission similarly to nonelderly patients. Therefore, the same infliximab trough concentration target can be used in therapeutic drug monitoring. The hazards of severe adverse events and malignancy increased with age, but not with infliximab exposure.

Abstract
BACKGROUND & AIMS Clinical remission, defined by a composite of patient reported outcomes and Mayo endoscopy subscore (MES) 0 or 1 is a recommended treatment target in patients with ulcerative colitis (UC). We estimated whether incorporating more rigorous remission definitions, of endoscopic remission (MES 0) and histologic remission, affects risk of relapse. METHODS Through a systematic review, we identified cohort studies in adults with UC in clinical remission that reported a minimum 12-month risk of clinical relapse, based on MES (0 vs 1) and/or histologic disease activity, in patients with endoscopic remission. Using random effects meta-analysis, we calculated relative and absolute risk of clinical relapse in patients with UC achieving different treatment targets. RESULTS In a meta-analysis of 17 studies that included 2608 patients with UC in clinical remission, compared to patients achieving MES 1, patients achieving MES 0 had a 52% lower risk of clinical relapse (relative risk, 0.48; 95% CI, 0.37-0.62). The median 12-month risk of clinical relapse in patients with MES 1 was 28.7%; the estimated annual risk of clinical relapse in patients with MES 0 was 13.7% (95% CI, 10.6-17.9). In a meta-analysis of 10 studies in patients in endoscopic remission (MES 0), patients who achieved histologic remission had a 63% lower risk of clinical relapse vs patients with persistent histologic activity (relative risk, 0.37; 95% CI, 0.24-0.56). Estimated annual risk of clinical relapse in who achieved achieving histologic remission was 5.0% (95% CI, 3.3-7.7). CONCLUSIONS In a systematic review and meta-analysis of patients with UC in clinical remission, we observed that patients achieving more rigorous treatment endpoints (endoscopic and histologic remission) have a substantially lower risk of clinical relapse compared with patients achieving clinical remission.

Abstract
BACKGROUND Clinical remission is the recommended treatment target in ulcerative colitis. The predictors and outcomes of achieving histologic remission within a treat-to-target paradigm are not well established. AIM To evaluate the predictors and outcomes of achieving histologic remission in patients with ulcerative colitis treated-to-target of endoscopic healing (modified Mayo endoscopy score 0 or 1). METHODS We conducted a retrospective cohort study in adults with active ulcerative colitis (modified Mayo endoscopy score 2 or 3), whose treatment was iteratively optimised to achieve endoscopic healing. We identified predictors of achieving histologic remission, and outcomes (risk of symptomatic relapse, and ulcerative colitis-related hospitalisation and/or surgery) of achieving histologic remission vs persistent histologic activity, using Cox proportional hazard analysis. RESULTS Of the 411 patients with clinically active ulcerative colitis, 270 achieved endoscopic healing. Of the 270 patients, 55% simultaneously achieved histologic remission. Depth of endoscopic healing at final endoscopic assessment was the only independent determinant of histologic remission (modified Mayo endoscopy score 0 vs 1: odds ratio, 0.31 [95% confidence intervals, 0.18-0.52]). Over 28 months, achieving histologic remission was associated with a lower risk of clinical relapse (1-year cumulative risk: 18.7% vs 29.5%; adjusted hazard ratio, 0.56 [0.37-0.85]), and lower risk of hospitalisation (hazard ratio, 0.44 [0.20-0.94]). The incremental benefit of achieving histologic remission was observed only in patients achieving Mayo endoscopy score 1, but not Mayo endoscopy score 0. CONCLUSIONS In patients with active ulcerative colitis treated-to-target of endoscopic healing, 55% simultaneously achieved histologic remission. Histologic remission, particularly in patients achieving modified Mayo endoscopy score 1, was associated with favourable outcomes. Treating to a target of histologic remission over endoscopic healing requires prospective evaluation.

A phase 2B randomised trial of hyperbaric oxygen therapy for ulcerative colitis patients hospitalised for moderate to severe flares. Aliment Pharmacol Ther 2020; 52:955-963.

Abstract
BACKGROUND Hyperbaric oxygen has been reported to improve disease activity in hospitalised ulcerative colitis (UC) patients. AIM To evaluate dosing strategies with hyperbaric oxygen for hospitalised UC patients. METHODS We enrolled UC patients hospitalised for acute flares (Mayo score 6-12). Initially, all patients received 3 days of hyperbaric oxygen at 2.4 atmospheres (90 minutes with two air breaks) in addition to intravenous steroids. Day 3 responders (reduction of partial Mayo score ≥ 2 points and rectal bleeding score ≥ 1 point) were randomised to receive a total of 5 days vs 3 days of hyperbaric oxygen. RESULTS We treated 20 patients with hyperbaric oxygen (75% prior biologic failure). Day 3 response was achieved in 55% (n = 11/20), with significant reductions in stool frequency, rectal bleeding and CRP (P < 0.01). A more significant reduction in disease activity was observed with 5 days vs 3 days of hyperbaric oxygen (P = 0.03). Infliximab or colectomy was required in only three patients (15%) despite a predicted probability of 80% for second-line therapy. Day 3 hyperbaric oxygen responders were less likely to require re-hospitalisation or colectomy by 3 months vs non-responders (0% vs 66%, P = 0.002). No treatment-related adverse events were observed. CONCLUSION Hyperbaric oxygen appears to be effective for optimising response to intravenous steroids in UC patients hospitalised for acute flares, with low rates of re-hospitalisation or colectomy at 3 months. An optimal clinical response is achieved with 5 days of hyperbaric oxygen. Larger phase 3 trials are needed to confirm efficacy and obtain labelled approval.

Abstract
INTRODUCTION Crohn's disease and ulcerative colitis, the two major forms of inflammatory bowel disease (IBD), are chronic disabling conditions characterised by flares followed by periods of remission. However, patients with IBD are seen every 3-6 months in the outpatient clinic, and the occurrence of a flare between two outpatient visits is not captured. To our knowledge, there is no validated patient-reported outcome (PRO) tool to measure the phenomenon of flare in IBD. This study aimed to use an innovative methodology to collect messages posted by patients in an internet forum for developing and validating a PRO measuring flare in IBD. METHODS AND ANALYSIS The design involves (1) computer engineering sciences for scraping extraction of messages posted in an internet forum and for identification of messages related to flare; (2) qualitative methods for thematic content analyse of the messages posted, for candidate items generation, for items selection (Delphi process) and for items adjustment ('think-aloud' interviews) and (3) quantitative methods for psychometric validation of the PRO. ETHICS AND DISSEMINATION Ethical approval was obtained from the Comité de Protection des Personnes (CPP) CPP Nord-Ouest I (19.07.15.44139) in November 2019. The project aims to provide a tool to evaluate IBD flare in current medical practice that is constructed with patients' perspectives. Items generation from a source corresponding to exchanges in an internet forum is an innovative method in this field and provides a wider coverage of qualitative data. If such a forum can result in interesting material, then this could be a new methodological perspective for generating items for questionnaires. Findings will be reported and disseminated widely through international peer-reviewed journal publications, oral and poster presentations at scientific conferences. TRIAL REGISTRATION NUMBER NCT04180345.

Abstract
INTRODUCTION We applied the Grading of Recommendations, Assessment, Development, and Evaluation framework to evaluate the performance of fecal calprotectin (FC) as an alternative to endoscopy in patients with moderate-to-severe ulcerative colitis (UC) treated with a biologic agent or tofacitinib. METHODS Individual participant data from the trials of infliximab, golimumab, vedolizumab, and tofacitinib for UC were pooled to generate prevalence of endoscopic activity (Mayo endoscopy score) across different combinations of the rectal bleeding score (RBS) and stool frequency score (SFS). These estimates were then combined with the data from an updated systematic review of the operating properties of FC to generate clinical scenario-specific assessments of the performance of FC as a predictor of endoscopic disease activity. A prespecified threshold of acceptability for false-negative (FN) and false-positive (FP) test results was set at 5%. RESULTS For patients with UC achieving RBS 0 + SFS 0/1, FC ≤ 50 μg/g may avoid endoscopy in 50% patients with a FN rate <5%. Similarly, for patients with RBS 2/3 + SFS 2/3, FC ≥ 250 μg/g potentially avoids endoscopy in approximately 50% patients with an FP rate <5%. The greatest uncertainty in the diagnostic performance for FC was observed in patients with UC achieving RBS 0 but having SFS 2/3, where FN and FP rates were consistently >10%, and endoscopic evaluation may be warranted. DISCUSSION Two clinical scenarios were identified where FC can be used with confidence for monitoring treatment response to biologics or tofacitinib in patients with UC without the requirement for endoscopy.
