RESUMO
Background/Aims: Obtaining and maintaining corticosteroid-free remission are important goals of treatment for ulcerative colitis (UC). Characteristics associated with achieving corticosteroid-free remission were assessed in filgotinib-treated patients in SELECTION, a 58-week, phase 2b/3 trial in moderately to severely active UC. Methods: This post hoc analysis used data from filgotinib-treated patients receiving corticosteroids at maintenance baseline in SELECTION. Univariate logistic regression was performed to assess induction baseline characteristics associated with 6 months of corticosteroid-free remission at week 58, defined as clinical remission without using corticosteroids for at least 6 months. Results: At maintenance baseline, 92 and 81 patients were receiving corticosteroids in the filgotinib 200 mg and filgotinib 100 mg groups, respectively. Age, body mass index, history of pancolitis, disease duration, fecal calprotectin levels, C-reactive protein levels, Mayo Clinic Score, concomitant corticosteroids, immunomodulators, and aminosalicylates had no statistically significant effect on the likelihood of achieving corticosteroid-free remission. Baseline characteristics associated with increased odds of corticosteroid-free remission were Mayo Clinic Endoscopic Subscore of 2 (vs. 3) in the filgotinib 200 mg and filgotinib 100 mg groups, and female (vs. male) sex, current (vs. former or never) smoking, and being biologicnaive (vs. experienced) in the filgotinib 200 mg group. Conclusions: Steroid tapering can be achieved in patients with UC receiving filgotinib 200 mg independently of baseline characteristics such as clinical activity and duration of illness. However, the likelihood of achieving corticosteroid-free remission was higher among patients who were biologic-naive, current smokers, had low endoscopic inflammatory burden and who were female.
RESUMO
BACKGROUND: Crohn's disease (CD) significantly affects patients' health-related quality of life and well-being. AIMS: Communicating Needs and Features of IBD Experiences (CONFIDE) survey explores the experience and impact of moderate-to-severe CD symptoms on patients' lives and identifies communication gaps between patients and health care professionals (HCPs). METHODS: Online, quantitative, cross-sectional surveys of patients, and HCPs were conducted in the United States (US), Europe (France, Germany, Italy, Spain, United Kingdom), and Japan. Criteria based on previous treatment, steroid use, and/or hospitalization defined moderate-to-severe CD. US and Europe data are presented as descriptive statistics. RESULTS: Surveys were completed by 215 US and 547 European patients and 200 US and 503 European HCPs. In both patient groups, top three symptoms currently (past month) experienced were diarrhea, bowel urgency, and increased stool frequency, with more than one-third patients wearing diaper/pad/protection at least once a week in past 3 months due to fear of bowel urgency-related accidents. HCPs ranked diarrhea, blood in stool, and increased stool frequency as the most common symptoms. Although 34.0% US and 27.2% European HCPs ranked bowel urgency among the top five symptoms affecting patient lives, only 12.0% US and 10.9% European HCPs ranked it among top three most impactful symptoms on treatment decisions. CONCLUSION: Bowel urgency is common and impactful among patients with CD in the US and Europe. Differences in patient and HCP perceptions of experiences and impacts of bowel urgency exist, with HCPs underestimating its burden. Proactive communication between HCPs and patients in clinical settings is crucial for improving health outcomes in patients with CD.

Patients with Crohn's disease are at higher risk of opportunistic infection, especially if treated with immunosuppressive therapy. Cytomegalovirus has been reported to cause ulcerated lesions mainly in the lower gastrointestinal tract of inflammatory bowel disease patients. We herein report a rare case of Crohn's disease complicated with cytomegalovirus esophagitis, which was difficult to distinguish from exacerbation of Crohn's disease. Diagnostic values of clinical course, blood tests, endoscopic and histological examinations are limited but the present case was therapeutically diagnosed by antiviral therapy in combination with histological evidence of cytomegalovirus.

BACKGROUND: Carbohydrate sulfotransferase 15 (CHST15) is an enzyme biosynthesizing matrix glycosaminoglycan that modulates tissue remodeling. We evaluated the efficacy of add-on submucosal injections of GUT-1, the RNA oligonucleotide inhibitor of CHST15, to ongoing anti-tumor necrosis factor (TNF) antibody treatment in patients with moderate-to-severe ulcerative colitis (UC). METHODS: This was an open-label study of 250 nM of GUT-1 by endoscopic submucosal injections at weeks 0, 2, 4 in five UC patients who lost response during maintenance treatment to anti-TNF antibodies. The primary endpoint was the rate of endoscopic improvement at week 6 and secondary endpoints included the rates of clinical remission by modified Mayo Score (mMS). Patients received follow-up observation with continuous maintenance treatment by the same anti-TNF antibody till the time of clinical recurrence or for overall 52 weeks. RESULTS: At week 6, rates of endoscopic improvement and clinical remission were 80% (n = 4/5) and 60% (n = 3/5), respectively. The mean Endoscopy Subscore was reduced from 2.4 (95%CI: 1.7 to 3.1) at baseline, to 1.0 (95%CI: 0.1 to 1.9) at week 6. The mean mMS was reduced from 7.8 (95%CI: 6.2 to 9.4) to 1.3 (95%CI: 2.9 to 4.3). GUT-1 was well tolerated. Three patients did not show clinical recurrence for 52 weeks. All three corticosteroid-dependent patients showed no corticosteroid exposure for at least 24 weeks after achieving clinical remission. Multiple dosing was also well tolerated. CONCLUSIONS: Add-on multiple injections of GUT-1 to ongoing anti-TNF antibody was able to induce rapid and durable clinical responses in UC patients who lost response to anti-TNF therapy. TRIAL REGISTRATION: Clinical trial Registration Number (Japan): UMIN000020900.
RESUMO
BACKGROUND: Endoscopic healing (EH) is a therapeutic target in ulcerative colitis (UC). However, even patients who have achieved EH relapse frequently. AIMS: To investigate the association between recent steroid use and relapse risk in UC patients with EH. METHODS: This multi-centre cohort study included 1212 UC patients with confirmed EH (Mayo endoscopic subscore ≤1). We excluded patients with current systemic steroid use or history of advanced therapy. We divided patients into a recent steroid group (last systemic steroid use within 1 year; n = 59) and a non-recent or steroid-naïve group (n = 1153). We followed the patients for 2 years to evaluate relapse, defined as induction of systemic steroids or advanced therapy. We used logistic regression to estimate the odds ratio (OR) of relapse. RESULTS: Relapse occurred in 28.8% of the recent steroid group and 5.6% of the non-recent/steroid-naïve group (multi-variable-adjusted OR 5.53 [95% CI 2.85-10.7]). The risk of relapse decreased with time since the last steroid use: 28.8% for less than 1 year after steroid therapy, 22.9% for 1 year, 16.0% for 2 years and 7.9% beyond 3 years, approaching 4.0% in steroid-naïve patients. (ptrend <0.001). CONCLUSIONS: Even for patients with UC who achieved EH, the risk of relapse remains high following recent steroid therapy. Physicians need to consider the duration since last steroid use to stratify the relapse risk in UC patients with EH.

BACKGROUND & AIMS: Withdrawal of immunomodulators (IMMs) or tumor necrosis factor (TNF) antagonists in patients with inflammatory bowel diseases (IBDs) in remission on combination therapy is attractive. We evaluated the efficacy and safety of (1) IMM, or (2) TNF antagonist withdrawal in patients with IBD in sustained remission on combination therapy. METHODS: Through a systematic review till March 31, 2023, we identified randomized controlled trials (RCTs) that compared the efficacy and safety of IMM or TNF antagonist withdrawal vs continued combination therapy, in patients with IBD in sustained corticosteroid-free clinical remission for >6 months on combination therapy. Primary outcome was risk of relapse and serious adverse events at 12 months. We conducted meta-analysis to calculate relative risk (RR) and 95% confidence interval (CI) and used Grading of Recommendations Assessment, Development and Evaluation (GRADE) to appraise certainty of evidence. RESULTS: We identified 8 RCTs with 733 patients (77% with Crohn's disease, 91% on infliximab-based combination therapy). On meta-analysis of 5 RCTs, there was no difference in the risk of relapse between patients with IMM withdrawal (continued TNF antagonist monotherapy) vs continued combination therapy (16.8% vs 14.9%; RR, 1.15; 95% CI, 0.75-1.76) without heterogeneity (low certainty of evidence). TNF antagonist withdrawal (continued IMM monotherapy) was associated with 2.4-times higher risk of relapse compared with continuing combination therapy (31.5% vs 11.2%; RR, 2.35; 95% CI, 1.38-4.01), with minimal heterogeneity (low certainty of evidence). There was no difference in the risk of serious adverse events with IMM or TNF antagonist withdrawal vs continued combination therapy. CONCLUSIONS: In patients with IBD in sustained corticosteroid-free clinical remission for >6 months on combination therapy, de-escalation with TNF antagonist withdrawal, but not IMM withdrawal, was associated with an increased risk of relapse.

BACKGROUND: Single nucleotide polymorphisms (SNPs) of the MEFV gene may modify inflammatory bowel disease (IBD) activity. The prevalence of MEFV gene SNPs in IBD patients and their involvement in IBD pathophysiology remains unclear. METHODS: We analyzed 12 MEFV gene SNPs in peripheral leukocytes of Japanese IBD patients (Crohn's disease [CD]: 69 patients, ulcerative colitis: 32 patients) by polymerase chain reaction using next-generation DNA sequencing and evaluated their prevalence and association with the disease characteristics. Inflammasome activity and mature interleukin (IL)-1ß and IL-18 production were evaluated in peripheral blood mononuclear cells obtained from CD patients stimulated with lipopolysaccharides and adenosine triphosphate, and compared between those with and without the E148Q SNP. COL1A1 and HSP47 gene expression was analyzed in CCD-18Co cells costimulated with IL-1ß and other inflammatory cytokines. RESULTS: The prevalence of MEFV gene SNPs in IBD patients was similar to that in the human gene database. E148Q was the most common SNP. Compared with CD patients without E148Q, those with E148Q had a significantly greater frequency of the stricture phenotype, and their peripheral blood mononuclear cells exhibited significantly higher IL-1ß and IL-18 levels and higher caspase-1 activity. IL-1ß and IL-17A synergistically increased COL1A1 and HSP47 gene expression. CONCLUSIONS: MEFV gene SNPs, including E148Q, modify the behavior of CD. IL-1ß and IL-18 are produced through enhanced caspase-1 activity in monocytes of CD patients with E148Q. IL-1ß promotes gene expression of fibrosis-related genes by cooperating with IL-17A in myofibroblasts. Therefore, E148Q might be a disease-modifying gene associated with the fibrostenosis phenotype in CD patients.
MEFV gene single nucleotide polymorphisms, including E148Q, modify the behavior of Crohn's disease to form stenosis. Interleukin-1ß is produced through enhanced caspase-1 activity in monocytes of Crohn's disease patients with E148Q, and promotes gene expression of fibrosis-related genes by cooperating with interleukin-17A in myofibroblasts.
RESUMO
INTRODUCTION: Biosimilar CT-P13 was approved with limited data from clinical trials compared to the originator infliximab in biologic-naïve patients with rheumatoid arthritis. Three prospective post-marketing surveillance studies have been conducted in Japanese biologic-naïve patients and switched patients from biologics including the originator infliximab. OBJECTIVE: We performed an integrated analysis of final data from three post-marketing studies to provide long-term safety and efficacy data of CT-P13 in a real-world clinical setting. METHODS: A total of 1816 patients consisting of 987 patients with rheumatoid arthritis, 342 patients with Crohn's disease, 322 patients with ulcerative colitis, and 165 patients with psoriasis were evaluated for safety. Efficacy was assessed in 1150 patients whose disease parameter values were serially collected. RESULTS: Adverse drug reactions were reported in 24.2% of all patients. The incidence of adverse drug reactions differed by the prior treatment status with biologics: 30.5% in patients naïve to biologics, 17.0% in patients switched from the originator infliximab, and 33.5% in patients switched from other biologics. Infusion reactions were the most frequent adverse drug reactions (8.2%), and its incidence was significantly higher in patients with ulcerative colitis and an allergy history in a multivariable Cox regression analysis. Infection was the second most frequent (6.1%), but tuberculosis only occurred in four patients (0.2%). The incidence of infection was low in patients with Crohn's disease and psoriasis, and significant risk factors were an allergy history, comorbidities, and concomitant steroid use. Interstitial lung disease occurred in 16 patients (0.9%), including 11 patients with rheumatoid arthritis. With CT-P13 therapy, disease activity parameters decreased similarly in all four diseases, although long-term drug discontinuation rates because of inefficacy varied by disease. In naïve patients, the disease activity parameters decreased rapidly and the proportion of patients in remission increased. Patients switched from infliximab maintained lowered parameter levels with infliximab pretreatment. Decreases were also observed in patients switched from other biologics, but discontinuations were most often because of insufficient efficacy. CONCLUSIONS: The integrated analysis of a large number of patients detected no new safety signals with long-term CT-P13 treatment. Efficacy in rheumatoid arthritis, psoriasis, Crohn's disease, and ulcerative colitis cases was confirmed in biologic-naïve patients and switched patients from the originator infliximab or other biologics.

OBJECTIVE: Tofacitinib is an oral Janus kinase inhibitor approved for the treatment of ulcerative colitis (UC). The objective of this study was to evaluate the long-term cost-effectiveness of tofacitinib versus current biologics, considering combinations of first-line (1L) and second-line (2L) therapies, from a Japanese payer's perspective in patients with moderate-to-severe active UC following an inadequate response to conventional therapy and in those who were naïve to biologics. METHODS: A cost-effectiveness analysis was conducted during the time horizon specified in the Markov model, which considers a patient's lifetime as 60 years and an annual discount rate of 2% on costs and effects. The model compared tofacitinib with vedolizumab, infliximab, adalimumab, golimumab, and ustekinumab. The time of active treatment was divided into induction and maintenance phases. Patients not responding to their biologic treatment after induction or during the maintenance phase were switched to a subsequent line of therapy. Treatment response and remission probabilities (for induction and maintenance phases) were obtained through a systematic literature review and a network meta-analysis that employed a multinomial analysis with fixed effects. Patient characteristics were sourced from the OCTAVE Induction trials. Mean utilities associated with UC health states and adverse events (AEs) were obtained from published sources. Direct medical costs related to drug acquisition, administration, surgery, patient management, and AEs were derived from the JMDC database analysis, which corresponded with the medical procedure fees from 2021. The drug prices were adjusted to April 2021. Further validation through all processes by clinical experts in Japan was conducted to fit the costs to real-world practices. Scenario and sensitivity analyses were also performed to confirm the accuracy and robustness of the base-case results. RESULTS: In the base-case, the treatment pattern including 1L tofacitinib was more cost-effective than vedolizumab, infliximab, golimumab, and ustekinumab for 1L therapies in terms of cost per quality-adjusted life year (QALY) gained (based on the Japanese threshold of 5,000,000 yen/QALY [38,023 United States dollars {USD}/QALY]). The base-case results demonstrated that the incremental costs would be reduced for all biologics, and decreases in incremental QALYs were observed for all biologics other than adalimumab. The incremental cost-effectiveness ratio (ICER) was found to be dominant for adalimumab; for the other biologics, it was found to be less costly and less efficacious. The efficiency frontier on the cost-effectiveness plane indicated that tofacitinib-infliximab and infliximab-tofacitinib were more cost-effective than the other treatment patterns. When infliximab-tofacitinib was compared with tofacitinib-infliximab, the ICER was 282,609,856 yen/QALY (2,149,157 USD/QALY) and the net monetary benefit (NMB) was -12,741,342 yen (-96,894 USD) with a threshold of 5,000,000 yen (38,023 USD) in Japan. Therefore, infliximab-tofacitinib was not acceptable by this threshold, and tofacitinib-infliximab was the cost-effective treatment pattern. CONCLUSION: The current analysis suggests that the treatment pattern including 1L tofacitinib is a cost-effective alternative to the biologics for patients with moderate-to-severe UC from a Japanese payer's perspective.

BACKGROUND AND AIMS: The efficacy of new therapies for ulcerative colitis [UC] is usually influenced by previous biologic use. These post hoc analyses of SELECTION, a placebo-controlled phase 2b/3 trial in patients with moderately to severely active UC, evaluated the efficacy of filgotinib, an oral Janus 1 kinase preferential inhibitor, with respect to prior biologic failure. METHODS: The effect of filgotinib 200 mg (FIL200) relative to placebo was compared in biologic-naïve and biologic-failed patient groups, and in further subgroups by number of failed biologics [1 or >1], biologic mechanism of action [MoA] classes [1 or 2] and tumour necrosis factor [TNF] antagonists [1 or >1]. Odds ratios [ORs] for clinical remission at week 10 [induction] and hazard ratios [HRs] for protocol-specific disease worsening [PSDW] from week 11 to week 58 [maintenance] were calculated. RESULTS: At week 10, FIL200-treated patients were more likely to achieve clinical remission than placebo-treated patients in the biologic-naïve (OR [95% confidence interval, CI]: 1.98 [1.14-3.44]) and biologic-failed (3.91 [1.33-11.48]) groups. During maintenance, FIL200-treated patients had a reduced risk of PSDW in the biologic-naïve (HR [95% CI]: 0.22 [0.11-0.44]) and biologic-failed (0.22 [0.12-0.40]) groups, and in all biologic-failed subgroups (except >1 TNF antagonist failure). The data suggest that the likelihood of PSDW at week 58 increased with increasing numbers of failed biologics. CONCLUSIONS: FIL200 induced and maintained benefits relative to placebo regardless of previous biologic use; however, the estimated therapeutic benefit was greatest in biologic-naïve patients and patients previously treated with one biologic or biologic MoA class.

BACKGROUND/AIMS: Risks of long-term steroid use in patients with ulcerative colitis (UC) outweigh the benefits, thus dosing should be tapered once a response is achieved. Colonoscopy is a key technique for assessing disease severity and optimizing treatment involving steroids. This retrospective longitudinal cohort study of patients with UC explored factors associated with the duration of systemic steroid use. METHODS: The Japan Medical Data Center database, an employer-based insurance claims database, was used to select individuals initiating prednisolone, with a prescription issued between January 1, 2010, and January 31, 2018. The study included adults with a confirmed diagnosis of UC, who had received ≥1 year of continuous treatment with 5-aminosalicylic acid, biologics, or thiopurine. Factors associated with prednisolone duration were assessed using a multivariate regression model. RESULTS: Median duration of prednisolone treatment was 98 days, and colonoscopy was performed ≤1 month before or at the first prescription of prednisolone (index date) in 32.8% of patients (607/1,853). Shorter durations of prednisolone treatment were associated with colonoscopy ≤1 month before or at the index date and higher prednisolone dose at index date, with incidence rate ratios (IRRs) of 0.776 (95% confidence interval [CI], 0.682-0.884; P<0.001) and 0.998 (95% CI, 0.996-1.000; P=0.018), respectively. Charlson Comorbidity Index scores of 1 and ≥2 predicted longer prednisolone treatment (IRR, 1.332; 95% CI, 1.174-1.511; P<0.001 and IRR, 1.599; 95% CI, 1.357-1.885; P<0.001, respectively). CONCLUSIONS: Performing colonoscopy before or at the time of initiating steroid was associated with a shorter duration of steroid use in patients with UC.
RESUMO
BACKGROUND: Pneumatosis intestinalis (PI) is a rare condition characterized by gas collection in the intestinal wall. We aimed to determine the etiology and affected segments associated with complications, treatment, and outcome. METHODS: We conducted a multicenter epidemiological survey using a standardized data collection sheet in Japan. Complicating PI was defined as strangulation or bowel necrosis, bowel obstruction, adynamic ileus, sepsis, shock, and massive gastrointestinal bleeding requiring blood transfusion. RESULTS: We enrolled 167 patients from 48 facilities. Multivariate analysis revealed that older age (adjusted OR, 1.05 and 95% confidence intervals [CI], 1.02-1.09, P = 0.0053) and chronic kidney disease (adjusted OR, 13.19 and 95% CI 1.04-167.62, P = 0.0468) were independent predictors of the small-bowel-involved type. Complicating PI was associated with the small-bowel-involved combined type (adjusted OR, 27.02 and 95% CI 4.80-152.01, P = 0.0002), the small-bowel-only type (adjusted OR, 3.94 and 95% CI 1.02-15.27, P = 0.0472), and symptomatic PI (adjusted OR, 16.24 and 95% CI 1.82-145.24, P = 0.0126). Oxygen therapy was performed in patients with a past history of bowel obstruction (adjusted OR, 13.77 and 95% CI 1.31-144.56, P = 0.0288) and surgery was performed in patients with complicating PI (adjusted OR, 8.93 and 95% CI 1.10-72.78, P = 0.0408). Antihypertensives (adjusted OR, 12.28 and 95% CI 1.07-140.79, P = 0.0439) and complicating PI (adjusted OR, 11.77 and 95% CI 1.053-131.526; P = 0.0453) were associated with exacerbation of PI. The complicating PI was the only indicator of death (adjusted OR, 14.40 and 95% CI 1.09-189.48, P = 0.0425). DISCUSSION: Small-bowel-involved type and symptomatic PI were associated with complications which were indicators of poor prognosis.

BACKGROUND AND AIM: Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). We present safety and efficacy data from patients from East Asia (Japan, Korea, and Taiwan) in OCTAVE Open, an open-label, long-term extension study. METHODS: Patients in remission at OCTAVE Open baseline received tofacitinib 5 mg twice daily (BID); all others received tofacitinib 10 mg BID. Proportions and IRs (unique patients with events/100 patient-years) were calculated for adverse events (AEs) of special interest. Efficacy endpoints were evaluated up to 36 months. RESULTS: In OCTAVE Open, 105/944 patients were from East Asia (tofacitinib 5 mg BID, n = 22; tofacitinib 10 mg BID, n = 83). Overall, 87.6% and 24.8% of patients had AEs and serious AEs, respectively; IRs (95% CI) for AEs of special interest were herpes zoster (HZ; non-serious and serious), 6.07 (3.40-10.02); serious infections, 1.47 (0.40-3.76); opportunistic infections, 1.91 (0.62-4.45); major cardiovascular adverse events, 0.37 (0.01-2.04); malignancies (excluding non-melanoma skin cancer [NMSC]), 0.37 (0.01-2.04); and NMSC, 0.00 (0.00-1.35). No deaths, venous thromboembolic events, or gastrointestinal perforations occurred. At month 36, 68.2% and 54.2% of patients had a clinical response, 68.2% and 53.0% had endoscopic improvement, and 63.6% and 49.4% were in remission with tofacitinib 5 and 10 mg BID, respectively. CONCLUSIONS: The HZ IR in East Asian patients was numerically higher versus the global study population; excluding HZ, tofacitinib safety and efficacy were consistent with the global study population.

BACKGROUND: The increasing incidence of older-onset ulcerative colitis (UC), which has a higher risk of surgery, is a global health issue. However, data regarding intravenous steroid treatment, one of the important treatment options to avoid surgery, for older-onset UC is lacking. AIMS: To evaluate the association between onset age and effectiveness of intravenous steroids in UC. METHODS: This retrospective multicentre (27 facilities) cohort study included moderate-to-severe hospitalised UC patients who underwent their first intravenous steroids between April 2014 and July 2019. The primary outcome was clinical remission at day 30, using two-item patient-reported outcome scoring. The key secondary outcomes were risks of surgery and adverse events (death, infection and venous thrombosis) within 90 days. A modified Poisson regression model was used for analysis. RESULTS: Overall, 467 UC patients (384 younger-onset and 83 older-onset) were enrolled. Clinical remission at day 30 was observed in 252 (65.6%) among younger-onset patients and 43 (51.8%) among older-onset patients (adjusted risk difference, -21.7% [95% CI, -36.1% to -7.2%]; adjusted risk ratio [ARR], 0.74 [95% CI, 0.59 to 0.93]). The risks of surgery and adverse events were higher in older-onset UC (20.5% vs. 3.1%; ARR, 8.92 [95% CI, 4.13 to 19.27], 25.3% vs. 9.1%; ARR, 2.19 [95% CI, 1.22 to 3.92], respectively). Four deaths occurred, all involving older-onset UC. The risks of infection and venous thrombosis were also higher in older-onset UC (18.1% vs. 8.6%, 7.2% vs. 0.5%, respectively). CONCLUSIONS: Older-onset was associated with a lower effectiveness of intravenous steroids with higher risks of surgery and adverse events in UC.

BACKGROUND: Immunomodulator therapy (e.g., thiopurines) has been linked to an increased malignancy risk, in patients with inflammatory bowel diseases (IBDs), which increases with treatment duration, based on studies mainly in Caucasian patients. However, our previous real-world study, of Japanese patients with IBDs, indicated no overall increased risk of non-Hodgkin lymphoma (NHL) with thiopurine treatment. OBJECTIVES: This subanalysis investigated the influence of thiopurine IBD treatment dose and duration, on incidence of NHL in Japanese patients. METHOD: The Medical Data Vision (MDV) claims database (17.8 million patients; April 2008-January 2018) was used to analyze incidence rate ratios (IRRs) of NHL, in eligible patients (≥1 diagnosis of ulcerative colitis or Crohn's disease) and no malignancy at diagnosis or first prescription of a thiopurine. Age- and sex-adjusted IRRs and 95% confidence interval for NHL were calculated as the incident cases compared in the subgroups versus the overall IBD population. RESULTS: Among 75,673 patients with IBDs, 103 cases of NHL were recorded. There was no overall increase in the risk of developing NHL among Japanese patients treated with thiopurines. The IRRs relative to the overall IBD population were 1.88, 1.42, and 0.38 for <1 year, 1-3 years, and ≥3 years of thiopurine treatment. There were no differences in NHL incidence when grouping patients by mean daily thiopurine dose prescribed, age, or disease subgroups. CONCLUSION: Dose or duration of thiopurine treatment did not explain a lack of increased risk of NHL with thiopurine use in Japanese patients with IBDs.

BACKGROUND AND AIMS: Starting biologic treatment early in the course of inflammatory bowel disease (IBD) may be associated with higher efficacy, especially in Crohn's disease (CD). METHODS: This was a systematic review and individual-patient data meta-analysis of all placebo-controlled trials of biologics approved for IBD at study inception (October 2015), using Vivli data-sharing platform. The primary outcome was the proportional biologic/placebo treatment effect on induction of remission in patients with short-duration (≤18 months) vs long-duration disease (>18 months) analyzed separately for CD and ulcerative colitis (UC). We used meta-regression to examine the impact of patients' characteristics on the primary outcome. RESULTS: We included 25 trials, testing infliximab, adalimumab, certolizumab, golimumab, natalizumab, or vedolizumab (6168 patients with CD and 3227 patients with UC). In CD, remission induction rates were higher in pooled placebo and patients in active arms with short-duration disease of ≤18 months (41.4% [244 of 589]) compared with disease duration of >18 months (29.8% [852 of 2857], meta-analytically estimated odds ratio, 1.33; 95% confidence interval, 1.09-1.64). The primary outcome, proportional biologic/placebo treatment effect on induction of remission, was not different in short-duration disease of ≤18 months (n = 589, odds ratio, 1.47; 95% confidence interval, 1.01-2.15) compared with longer disease duration (n = 2857, odds ratio, 1.43; 95% confidence interval, 1.19-1.72). In UC trials, both the proportional biologic/placebo remission-induction effect and the pooled biologic-placebo effect were stable, regardless of disease duration. Primary outcome results remained unchanged when tested using alternative temporal cutoffs and when modeled for individual patient's covariates, including prior anti-tumor necrosis factor exposure. CONCLUSIONS: There are higher rates of induction of remission with biologics and with placebo in early CD, resulting in a treatment to placebo effect ratio that is similar across disease durations. No such relationships between disease duration and outcomes was found in UC. PROSPERO registration: CRD42018041961.

BACKGROUND AND AIMS: Amiselimod is an oral selective S1P1 receptor modulator with potentially fewer adverse effects than fingolimod. We evaluated the safety, tolerability, and clinical efficacy of amiselimod in participants with moderate to severe active Crohn's disease. METHODS: This was a phase IIa, multicentre, randomised, double-blind, parallel group, placebo-controlled study comparing amiselimod 0.4 mg with placebo over a 14-Week treatment period. The primary endpoint of the study was the proportion of participants with clinical response (Crohn's Disease activity Index [CDAI] 100) from baseline at Week 12. RESULTS: A total of 180 patients were screened and 78 were randomised [40 to amiselimod 0.4 mg and 38 to placebo]. There was no significant difference in the proportion of patients achieving CDAI 100 at Week 12 on amiselimod 0.4 mg and on placebo [48.7% vs. 54.1%, respectively] (odds ratio [OR] [95% confidence interval]: 0.79 [0.31, 1.98]). The results from the secondary endpoint analyses supported the results of the primary endpoint analysis. Treatment with amiselimod 0.4 mg was generally well tolerated, with 71.8% of participants completing the 14-week treatment period. Seven participants had serious adverse events and four discontinued treatment in the amiselimod group. CONCLUSIONS: Amiselimod 0.4 mg for 12 weeks was not superior to placebo for the induction of clinical response [CDAI 100] in Crohn's disease. Treatment with amiselimod 0.4 mg was generally well tolerated and no new safety concerns related to amiselimod were reported in this study.

BACKGROUND: Mucosal healing is a treatment target for patients with ulcerative colitis. However, the relevance of proactive treatment for residual inflammation limited to the distal colon is unclear. MATERIALS AND METHODS: Patients with ulcerative colitis who had extensive colitis in clinical remission and underwent colonoscopy were retrospectively enrolled and followed up for 2 years. Patients with complete endoscopic remission (CER; Mayo endoscopic subscore [MES] of 0) and those with short-segment distal inflammation (SS; active inflammation only in the sigmoid colon and/or rectum with a proximal MES of 0) were compared for the incidence of minor (only symptomatic) and major (need for induction treatments or hospitalization) relapses. RESULTS: A total of 91 patients with CER and 54 patients with SS were identified and 63 relapses (47 minor and 16 major) were analyzed. Univariate analysis showed that minor relapses were significantly more frequent in the SS group than in the CER group (hazard ratio [HR], 2.22; 95% confidence interval [CI], 1.25-3.97), but major relapses were not more frequent in the SS group than in the CER group (HR, 1.78; 95% CI, 0.65-4.83). Multivariable analysis showed that SS was the only risk factor significantly associated with minor relapse (HR, 2.38; 95% CI, 1.31-4.36). When the SS group was stratified by MES of 1 vs 2/3, minor relapses were significantly more frequent in the subgroup with MES of 2/3 than in the CER group, whereas the incidence of major relapse remained similar. CONCLUSIONS: Residual short-segment distal inflammation is not a risk factor for major relapses as long as endoscopic remission is achieved in the proximal colon. Therefore, reactive but not proactive treatment may be appropriate for such lesions.

BACKGROUND: Real-world big data studies using health insurance claims databases require extraction algorithms to accurately identify target population and outcome. However, no algorithm for Crohn's disease (CD) has yet been validated. In this study we aim to develop an algorithm for identifying CD using the claims data of the insurance system. METHODS: A single-center retrospective study to develop a CD extraction algorithm from insurance claims data was conducted. Patients visiting the Kitasato University Kitasato Institute Hospital between January 2015-February 2019 were enrolled, and data were extracted according to inclusion criteria combining the Tenth Revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) diagnosis codes with or without prescription or surgical codes. Hundred cases that met each inclusion criterion were randomly sampled and positive predictive values (PPVs) were calculated according to the diagnosis in the medical chart. Of all cases, 20% were reviewed in duplicate, and the inter-observer agreement (Kappa) was also calculated. RESULTS: From the 82,898 enrolled, 255 cases were extracted by diagnosis code alone, 197 by the combination of diagnosis and prescription codes, and 197 by the combination of diagnosis codes and prescription or surgical codes. The PPV for confirmed CD cases was 83% by diagnosis codes alone, but improved to 97% by combining with prescription codes. The inter-observer agreement was 0.9903. CONCLUSIONS: Single ICD-code alone was insufficient to define CD; however, the algorithm that combined diagnosis codes with prescription codes indicated a sufficiently high PPV and will enable outcome-based research on CD using the Japanese claims database.
