Efficacy of vedolizumab during intravenous induction therapy in ulcerative colitis and Crohn's disease: post hoc analysis of patient-reported outcomes from the VISIBLE 1 and 2 studies. Eur J Gastroenterol Hepatol 2024; 36:404-415. [PMID: 38417060 PMCID: PMC10904001 DOI: 10.1097/meg.0000000000002728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Accepted: 11/11/2023] [Indexed: 03/01/2024]
Abstract
BACKGROUND Vedolizumab is an anti-α4β7 integrin antibody used to treat moderate to severe ulcerative colitis (UC) and Crohn's disease (CD). This post hoc analysis of patient-reported outcomes (PROs) from the VISIBLE 1 (NCT02611830) and 2 (NCT02611817) phase 3 studies evaluated onset of treatment effect on patient-reported symptoms during 6-week vedolizumab induction. METHODS Patient-reported stool frequency (SF) and rectal bleeding (RB) (UC Mayo score), and SF and abdominal pain (AP) in CD were collected via electronic diary from VISIBLE patients receiving one or more open-label intravenous (IV) vedolizumab induction doses (weeks 0 and 2). PRO data were analyzed using descriptive statistics. RESULTS Data from 994 patients (UC 383, CD 611) showed mean ratings for all PROs declined consistently week-on-week from baseline through week 6, with early onset of improvement. By week 2, 22% of patients with UC reported RB improvement (≥1-point reduction in RB subscore, 7-day mean), rising to 45% by week 6. By week 6, 18% of patients with UC achieved SF improvement (SF subscore 0; 21% antitumor necrosis factor alpha [anti-TNFα] naive, 13% anti-TNFα experienced). SF improvement in patients with CD (reduction of ≥3 stools, 7-day mean) was achieved by 32% at week 6 (34% anti-TNFα naive, 30% anti-TNFα experienced). Fewer patients with CD reported severe/moderate AP at week 6 (5.1%/28.5%) than baseline (14.6%/61.5%). SF decline appeared greater and faster for anti-TNFα-naive vs. anti-TNFα-experienced patients (UC and CD). CONCLUSION Results indicate early onset of patient-reported UC and CD symptom improvement during vedolizumab IV induction in VISIBLE 1 and 2.

Comparison of fecal calprotectin levels and endoscopic scores for predicting relapse in patients with ulcerative colitis in remission. World J Gastroenterol 2023; 29:6111-6121. [PMID: 38186681 PMCID: PMC10768409 DOI: 10.3748/wjg.v29.i47.6111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Revised: 08/24/2023] [Accepted: 11/29/2023] [Indexed: 12/19/2023] Open
Abstract
BACKGROUND Although the usefulness of endoscopic scores, such as the Mayo Endoscopic Subscore (MES), Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and Ulcerative Colitis Colonoscopic Index of Severity (UCCIS), and biomarkers such as fecal calprotectin (FC) for predicting relapse in ulcerative colitis (UC) has been reported, few studies have included endoscopic scores for evaluating the entire colon. AIM To compare the usefulness of FC value and MES, UCEIS, and UCCIS for predicting relapse in patients with UC in clinical remission. METHODS In total, 75 patients with UC in clinical and endoscopic remission who visited our institution between February 2019 and March 2022 were enrolled. The diagnosis of UC was confirmed based on the clinical presentation, endoscopic findings, and histology, according to the current established criteria for UC. Fecal samples were collected the day before or after the colonoscopy for measurement of FC. Endoscopic evaluations were performed using MES, UCEIS, and UCCIS. The primary outcome measure of this study was the assessment of the association between relapse within 12 mo and MES, UCEIS, UCCIS, and FC. The secondary outcome was the comparison between endoscopic scores and biomarkers in enrolled patients with UC with mucosal healing. RESULTS FC and UCCIS showed a significant correlation with UCEIS (r = 0.537, P < 0.001 and r = 0.957, P < 0.001, respectively). Receiver-operating characteristic analysis for predicting MES 0 showed that the area under the curve of UCCIS was significantly higher than that of FC (P < 0.01). During the 1-year observation period, 18 (24%) patients experienced a relapse, and both the FC and UCCIS of the relapse group were significantly higher than that of the remission group. The cut-off values for predicting relapse were set at FC = 323 mg/kg and UCCIS = 10.2. The area under the curve of the receiver-operating characteristic analysis for predicting relapse did not show a significant difference between FC and UCCIS. The accuracy of the endoscopic scores and biomarkers in predicting relapse was 86.7% for UCCIS, 85.3% for UCEIS, 76.0% for FC, and 73.3% for MES. CONCLUSION The three endoscopic scores and FC may predict UC relapse during clinical remission. Among these scores, UCEIS may be the most useful in terms of ease of evaluation and accuracy.

Abstract
Fecal calprotectin (FC) levels correlate with the disease activity of inflammatory bowel diseases (IBD); however, the utility of FC in predicting IBD relapse remains to be determined. We aim to evaluate the efficacy of fecal calprotectin in predicting the relapse of inflammatory bowel disease. We searched Pubmed (MEDLINE), Embase, Web of Science, and the Cochrane library databases up to 7 July 2021. Our study estimated the pooled sensitivity and specificity, summary receiver operating characteristic (SROC) curve, and the optimal cut-off value for predicting IBD relapse using a multiple threshold model. A total of 24 prospective studies were included in the meta-analysis. The optimal FC cut-off value was 152 μg/g. The pooled sensitivity and specificity of FC was 0.720 (0.528 to 0.856) and 0.740 (0.618 to 0.834), respectively. FC is a useful, non-invasive, and inexpensive biomarker for the early prediction of IBD relapse. An FC value of 152 μg/g is an ideal threshold to identify patients with a high relapse probability.

[PMID: 36769791 PMCID: PMC9918267 DOI: 10.3390/jcm12031142] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/02/2023] [Accepted: 01/29/2023] [Indexed: 02/04/2023] Open
Abstract
The i Support Therapy-Access to Rapid Treatment (iSTART) was an initiative to improve patient-centered management in mild-to-moderate ulcerative colitis (UC). Our aim was to update the iSTART recommendations in order to include fecal calprotectin (FC) in the monitoring of patients with UC and improve their management. Twelve physicians from nine countries worldwide attended a virtual international consensus meeting on 4 May 2022. Data from three systematic reviews were analyzed, and a new systematic review investigating all studies reporting measurement of FC at home was conducted. Based on literature evidence, statements were formulated, discussed, and approved by voting. Statements were considered approved if at least 75% of participants agreed with a proposed statement. Fourteen statements were approved. Based on this consensus, FC measurement should be routinely performed for monitoring patients with mild-to-moderate UC to identify disease relapses early and initiate an appropriate treatment. Further studies are needed to assess whether self-monitoring of FC is associated with better disease control and improved patients' quality of life.

Abstract
BACKGROUND & AIMS We evaluated the value of post-induction fecal calprotectin (FCP) concentration as a biomarker in patients with ulcerative colitis (UC) treated with a biologic. METHODS This post hoc analysis of the GEMINI 1/GEMINI LTS (N = 620) and VARSITY (N = 771) trials evaluated the cross-sectional accuracy of post-induction FCP in identifying endoscopic activity and histologic inflammation, and the prognostic performance of FCP in identifying patients most likely to achieve endoscopic and histologic remission or require colectomy and UC-related hospitalization. RESULTS The cross-sectional accuracy of FCP in identifying endoscopic activity and histologic inflammation was modest (63%-79%). However, a post-induction FCP concentration of ≤250 μg/g vs >250 μg/g was associated with a substantially higher probability of achieving clinical remission (odds ratio [OR], 4.03; 95% confidence interval [CI], 2.78-5.85), endoscopic remission (OR, 4.26; 95% CI, 2.83-6.40), and histologic remission (Robarts Histopathology Index: OR, 5.54; 95% CI, 3.77-8.14; Geboes grade: OR, 6.42; 95% CI, 4.02-10.26) at week 52 and a lower probability of colectomy over 7 years (hazard ratio, 0.296; 95% CI, 0.130-0.677) and UC-related hospitalization (hazard ratio, 0.583; 95% CI, 0.389-0.874). The association with colectomy was significant even among patients in symptomatic remission or with endoscopic improvement post-induction, and among patients with elevated FCP at baseline. CONCLUSIONS Although FCP had only modest cross-sectional accuracy in identifying disease activity, an FCP concentration of ≤250 μg/g vs >250 μg/g was associated with increased probability of achieving long-term clinical, endoscopic, and histologic remission, and reduced probability of colectomy and UC-related hospitalization (ClinicalTrials.gov: NCT00783718, NCT00790933, NCT02497469).

Abstract
BACKGROUND Indirect treatment comparisons using patient-level data are increasing in popularity within inflammatory bowel disease research. We compared the efficacy of adalimumab and vedolizumab for biologic-naïve moderate-severe ulcerative colitis (UC) using indirect comparisons of phase 3 clinical trials and compared the results to the RCT VARSITY. DESIGN Pooled analysis of patient-level data from 518 biologic-naïve patients with UC was performed using GEMINI-1 and ULTRA-1. Proportions of patients achieving week 6 clinical remission and clinical response were compared, and propensity score matching and multivariate logistic regression were used to account for potential confounders. These results were compared to those derived from VARSITY. RESULTS A numerically greater proportion of vedolizumab-treated patients from GEMINI-1 achieved week 6 clinical remission compared to those treated with adalimumab [136/388 (35.1%) vs. 38/130 (29.2%)]. Similar findings were observed among the propensity score matched cohort [33/110 (30.0%) vs. 25/110 (22.7%), adjusted OR (aOR) 1.56 (95% confidence interval (CI) 0.81-3.02), p = 0.187]. A similar magnitude for absolute difference in the proportions of patients achieving week 6 clinical remission was observed from VARSITY in vedolizumab compared to adalimumab [131/305 (43.0%) vs. 114/307 (37.1%), OR 1.27 (95% CI 0.92-1.76), p = 0.142]. CONCLUSIONS In this post hoc analysis, a similar magnitude in the absolute difference of efficacy at week 6 among biologic-naïve patients was observed using indirect comparisons of phase 3 clinical trial data as was observed in VARSITY. Indirect comparisons using patient-level clinical trial data could be used to inform drug choices for future head-to-head trials and guide positioning of drugs in the absence of head-to-head trials.

Intestinal Ultrasound Is Accurate to Determine Endoscopic Response and Remission in Patients With Moderate to Severe Ulcerative Colitis: A Longitudinal Prospective Cohort Study. Gastroenterology 2022; 163:1569-1581. [PMID: 36030056 DOI: 10.1053/j.gastro.2022.08.038] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 08/09/2022] [Accepted: 08/19/2022] [Indexed: 12/27/2022]
Abstract
BACKGROUND & AIMS Intestinal ultrasound (IUS) is noninvasive, cost-effective, and accurate to determine disease activity in ulcerative colitis (UC). In this study, we prospectively evaluated IUS for treatment response in a longitudinal cohort by using endoscopy and histology as gold standards. METHODS Consecutive patients with moderate to severe UC (endoscopic Mayo score [EMS] ≥2) starting tofacitinib treatment were included. Patients were evaluated at baseline and after 8 weeks of tofacitinib induction by means of clinical, biochemical, endoscopic (EMS and UC endoscopic index for severity), histologic (Robarts Histopathologic Index) and IUS assessments. Readers of IUS, endoscopy, and histology were blinded for all other outcomes. The primary outcome was difference in bowel wall thickness (BWT) for endoscopic improvement vs no endoscopic improvement. Endoscopic remission was defined as EMS = 0, improvement as EMS ≤1, and response as a decrease of EMS ≥1. RESULTS Thirty patients were included, with 27 patients completing follow-up. BWT correlated with EMS (ρ = 0.68, P < .0001), UC endoscopic index for severity (ρ = 0.73, P < .0001) and Robarts Histopathologic Index (ρ = 0.49, P = .002) at both time points. BWT in the sigmoid was lower in patients with endoscopic remission (1.4 mm vs 4.0 mm, P = .016), endoscopic improvement (1.8 mm vs 4.5 mm, P < .0001) and decrease in BWT was more pronounced in patients with endoscopic response (-58.1% vs -13.4%, P = .018). The most accurate cutoff values for BWT were 2.8 mm (area under the curve [AUC] 0.87) for endoscopic remission, 3.9 mm (AUC 0.92) for improvement, and decrease of 32% (AUC 0.87) for response. The submucosa was the most responsive wall layer. CONCLUSION IUS, importantly BWT as the single most important parameter, is highly accurate to detect treatment response when evaluated against endoscopic outcomes.

Early Clinical Remission Is a Predictor of Long-Term Remission with the Use of Vedolizumab for Ulcerative Colitis. Biomedicines 2022; 10:biomedicines10102526. [PMID: 36289788 PMCID: PMC9599457 DOI: 10.3390/biomedicines10102526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 10/03/2022] [Accepted: 10/06/2022] [Indexed: 11/19/2022] Open
Abstract
Vedolizumab (VDZ) is an α4β7 integrin-antibody used to manage refractory ulcerative colitis (UC). This retrospective multicenter study aimed to identify predictors of efficacy or the time points when evaluation of VDZ therapy for UC would be most useful. We compiled data on 87 patients with moderate to severe active UC that was treated with VDZ. Overall clinical remission (CR) rates at 6 weeks and 52 weeks after VDZ administration were 44.4% (bio-naïve 44.2%, bio-failure 44.8%) and 52.8% (bio-naïve 53.5%, bio-failure 51.7%) respectively. Also, 83.3% (bio-naïve 81.3%, bio-failure 85.7%) of patients achieved mucosal healing at week 52. Among patients with a CR at week 52, 73.3% had a CR at week 6. In contrast, of patients who discontinued VDZ, 82.4% had not reached a CR at week 6. Our study demonstrated that VDZ was effective in a large percentage of UC patients, with a high mucosal healing rate even after prior biological exposures. This suggests that VDZ can be a treatment option even in bio-failure cases. Additionally, it was considered that early CR can predict long-term remission and that week 6 can be a helpful evaluation point for treatment decisions when using VDZ for UC.

Abstract
Background: There is currently scarce knowledge about markers of early therapeutic response in patients with inflammatory bowel disease (IBD) treated with biologics. The aim of this study was to evaluate the role of fecal calprotectin (FC) as an early predictor of mucosal healing and clinical remission. Methods: Data from a multicenter series of 172 IBD patients treated with biologics between 2017 and 2020 were analyzed. Treatment outcomes were mucosal healing and clinical remission assessed at 2 years. FC levels were assessed at 14 weeks (post-induction), at 6 months, and yearly. The receiver operating characteristic (ROC) curve analysis was performed to calculate the best cut-off in % change of FC levels between post-induction and baseline predicting treatment outcomes. Sensitivity, specificity, and accuracy for several post-induction FC cut-off points were also calculated. Results: At 2 years, mucosal healing was noted in 77 patients (44.7%), of whom were 41 Crohn’s disease (CD) and 36 ulcerative colitis (UC) patients, whereas 106 patients experienced clinical remission (61.6%), of whom were 59 CD and 47 UC patients. Both baseline and post-induction FC levels were significantly higher in non-responders as compared to responders. On the other hand, FC decrease was less pronounced in non-responders. Similar results were observed in all subgroups, namely according to disease (CD vs. UC), or treatment used (TNF-inhibitors vs. vedolizumab). The best cut-off points were −86% in % change in FC levels to predict mucosal healing and −83% for clinical remission. Conclusions: The current study suggests a predictive role of post-induction FC assessment to predict treatment response in IBD patients treated with biologics.

Abstract
BACKGROUND Bowel ultrasonography is a non-invasive imaging tool that can repeatedly monitor ulcerative colitis (UC) activity. AIM This study aimed to determine whether early transabdominal or transperineal ultrasonography changes can predict subsequent clinical response to induction therapy in patients with UC. METHODS This single-centre prospective study explored ultrasonographic predictors for clinical remission (patient-reported outcome-2 ≤ 1 with no rectal bleeding subscore) at week 8 in patients with active UC who underwent induction therapy, in comparison with faecal calprotectin and C-reactive protein (measured at baseline, week 1 and week 8). Predictive factors were assessed using multivariable regression models and receiver-operating-characteristic curve analysis. RESULTS A total of 100 patients were analysed, of which 54 achieved remission at week 8. Baseline biomarker and ultrasonographic-parameter values were not predictive of remission. Contrastingly, change from baseline to week 1 in rectal bowel wall thickness measured using transperineal ultrasonography was an independent predictor of remission by week 8 (adjusted odds ratio is associated with a 1-mm decrease: 1.90 [95% confidence interval, 1.22-2.95]). In a subgroup analysis of the patients who did not achieve remission in 1 week, the predictive value of change in rectal bowel wall thickness remained high (AUC = 0.77 [95% confidence interval, 0.61-0.88]). CONCLUSION Improvement in rectal bowel wall thickness measured using transperineal ultrasonography at week 1 predicts treatment success and potentially facilitates decision making during the early course of induction therapy in UC.

Modeling Endoscopic Improvement after Induction Treatment With Mesalamine in Patients With Mild-to-Moderate Ulcerative Colitis. Clin Gastroenterol Hepatol 2022; 20:447-454.e1. [PMID: 33279779 PMCID: PMC8588993 DOI: 10.1016/j.cgh.2020.11.040] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Revised: 11/17/2020] [Accepted: 11/25/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND & AIMS Endoscopic improvement is an important treatment target for mild-to-moderate ulcerative colitis (UC). However, early endoscopic evaluation is not always feasible. We aimed to develop a clinical decision support tool to discriminate patients who have achieved endoscopic improvement from those with more severe inflammation following mesalamine induction therapy. METHODS We performed a post-hoc analysis of data from a phase 3 non-inferiority trial of 726 adults with mild-to-moderate UC treated with mesalamine. Multivariable logistic regression modeling determined associations between candidate variables and endoscopic improvement (Mayo endoscopic subscore=0-1 according to blinded central reading) at Week 8. Internal model validation was performed using bootstrap resampling. A clinical decision support tool was developed to stratify patients into low, intermediate, and high probability groups for endoscopic improvement. RESULTS Variables associated with endoscopic improvement at Week 8 included 50% reduction in fecal calprotectin from baseline (odds ratio [OR] 2.64, 95% CI:, 1.81, 3.85), reduction in rectal bleeding (OR 1.79 per point reduction, 95% CI: 1.35, 2.39), and improvement in physician global assessment (OR 2.32 per point improvement, 95% CI: 1.88, 2.85). The baseline Geboes score (OR 0.74 per grade, 95% CI: 0.65, 0.85) and prolonged disease duration (OR 0.95 per year, 95% CI: 0.92, 0.98) were negatively associated with endoscopic improvement. This model strongly discriminated endoscopic improvement in the development dataset (area under the curve [AUC] 0.84, 95% CI: 0.81, 0.87) and during validation (AUC 0.83). CONCLUSIONS We developed and validated a clinical decision support tool that has good discriminative performance for induction of endoscopic improvement in patients with mild-to-moderate UC treated with mesalamine.

Abstract
Vedolizumab is a gut-selective monoclonal antibody approved for the management of Crohn's disease and ulcerative colitis. The available data demonstrate a favourable response to dose escalation in patients with primary non-response or secondary loss of response to vedolizumab. While therapeutic drug monitoring has a proven clinical utility for tumour necrosis factor antagonists, the available guidance for therapeutic drug monitoring and dose escalation of vedolizumab is rather limited. The present review proposes a practical algorithm to use vedolizumab trough levels in the management of treatment failure. Therapeutic drug monitoring can differentiate underexposed patients from those with mechanistic failure. Underdosed patients can respond to dose escalation instead of unnecessarily switching to other treatment modalities. We also review the safety and potential cost-effectiveness of vedolizumab dose escalation, the role of antidrug antibodies and the possible applicability of this strategy to subcutaneous vedolizumab.

Abstract
INTRODUCTION: Prostaglandin E-major urinary metabolite (PGE-MUM) is a novel biomarker reflecting endoscopic activity in ulcerative colitis (UC). However, there are no studies investigating the efficacy of PGE-MUM as a biomarker for predicting relapse. We investigated whether PGE-MUM can predict clinical relapse of UC. METHODS: The measurement of PGE-MUM and endoscopic evaluation were performed in 70 patients with UC in clinical remission. The optimal cutoff values predicting relapse and relapse-free rate were analyzed. RESULTS: Sixteen patients (22.9%) relapsed during the 12-month follow-up. The median PGE-MUM value of relapsed patients at entry was significantly higher than that of patients in clinical remission (P = 0.008). The cutoff value of PGE-MUM predicting future relapse was 25.2 μg/g Cr by receiver-operating characteristic (ROC) analysis, and the area under the ROC curve was 0.721 (95% confidence interval: 0.556–0.886). The relapse-free rate of patients with PGE-MUM ≥25.2 μg/g Cr was significantly lower than that in patients with PGE-MUM <25.2 μg/g Cr (log-rank test: P < 0.001). The ROC analysis of UC patients with disease duration more than 1–8 years showed that duration of more than 5 years had the largest area under the ROC curve 0.821 (95% confidence interval: 0.583–1.000) and that the optimal cutoff value was 26.3 μg/g Cr. DISCUSSION: PGE-MUM is a reliable biomarker for predicting future relapse, particularly in UC patients with long-disease duration.

Abstract
OBJECTIVE To investigate the small intestinal bacterial overgrowth (SIBO) and to evaluate the intestinal barrier function in ulcerative colitis (UC) patients treated with mesalazine and rifaximin. METHODS 96 patients undergoing the methane-hydrogen breath test in our hospital from January 2018 to January 2020 were enrolled in the study group, and 40 healthy persons were enrolled in the control group during this period. The SIBO positive rate of the two groups were collected and compared. Then, the SIBO positive patients were divided into group A and group B. Group A and group B all received mesalazine, and group B received rifaximin plus. The clinical efficacy, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), and intestinal barrier function indexes like diamine oxidase (DAO) and D-lactic acid (DLA) were recorded and compared. RESULTS The study group presented higher SIBO positive rate compared with the control group (56% vs. 25%, P<0.05). After treatment, group B showed better clinical efficacy and lower levels of ESR and CRP than group A (all P<0.05). After treatment, the DAO and D-LA levels of the two groups were decreased, and presented lower levels in group B than group A (all P<0.05). CONCLUSION UC patients present a higher positive rate in SIBO. Mesalazine and rifaximin are applied to patients with mild to moderate UC, and their clinical efficacy has been significantly enhanced after the eradication of SIBO.

Abstract
BACKGROUND The Gemini trial failed to detect a significant difference in response rate for patients with ulcerative colitis (UC) randomized to standard (every 8 week) vedolizumab dosing vs escalated (every 4 week) dosing. Subsequent real-world data imply the Gemini trial design may have obscured a benefit of escalated dosing. AIMS We investigated outcomes after vedolizumab dose escalation for patients with UC. We also explored potential clinical predictors of dose escalation requirement. METHODS In this retrospective study, we included patients with UC who received vedolizumab between 1/2017-1/2019. We compared rates of clinical response (decrease in partial Mayo score by ≥ 2) and remission (partial Mayo < 2) for standard vs escalated dosing. RESULTS Among the 90 patients reviewed, 52 achieved and maintained remission on standard dosing. The average time to remission with standard dosing was 33.3 ± 6.6 weeks. After an average of 56.3 ± 7.4 weeks standard dosing, 24 patients (22 "partial responders" and 2 "non-responders") were dose-escalated. Of the 22 "partial responders" dose-escalated, 10 (45%) achieved remission, 10 (45%) achieved further improvement. Neither "non-responder" demonstrated further clinical benefit. Prior anti-tumor necrosis factor (anti-TNF) biologic exposure predicted dose escalation requirement (p = 0.008). Patients requiring dose escalation had more severe disease at baseline as measured by both full Mayo (p = 0.009) and partial Mayo scores (p = 0.01). CONCLUSIONS We show dose escalation benefited patients with UC who exhibit a "partial response" to standard dosing. Early vedolizumab dose escalation should be considered in both patients with severe disease and those with prior anti-TNF experience.

Abstract
Biological therapies are widely used for the treatment of ulcerative colitis. However, only a low proportion of patients achieve clinical remission and even less mucosal healing. There is currently scarce knowledge about the early markers of therapeutic response, with particular regard to mucosal healing. The aim of this prospective study was to evaluate the role of fecal calprotectin (FC) as early predictor of mucosal healing.

Abstract
BACKGROUND AND AIMS Serial measurements of luminal disease activity may facilitate inflammatory bowel disease management. Gastrointestinal ultrasound is an easily performed, non-invasive alternative to other assessment modes. However, its widespread use is limited by concerns regarding validity, reliability, and responsiveness. We systematically identified ultrasound scoring indices used to evaluate inflammatory bowel disease activity and examine their operating characteristics. METHODS Electronic databases were searched from inception to June 14, 2019 using pre-defined terms. Studies that reported on gastrointestinal ultrasound index operating properties in an inflammatory bowel disease population were eligible for inclusion. Study characteristics, index components, and operating property data [ie, validity, reliability, responsiveness, sensitivity, specificity, accuracy, positive predictive value, and negative predictive value] were extracted. The QUADAS-2 tool was used to examine study-level risk of bias. RESULTS Of the 2610 studies identified, 26 studies reporting on 21 ultrasound indices were included. The most common index components included bowel wall thickness, colour Doppler imaging, and bowel wall stratification. The correlation between ultrasound indices and references standards ranged r = 0.62-0.95 and k = 0.40-0.96. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive values ranged 39-100%, 63-100%, 73-100%, 57-100%, and 40-100%, respectively. Reliability and responsiveness data were limited. Most [92%, 24/26] studies received at least one unclear or high risk of bias rating. CONCLUSIONS Several gastrointestinal ultrasound indices for use in inflammatory bowel disease have been developed. Future research should focus on fully validating existing or novel gastrointestinal ultrasound scoring instruments for assessment of Crohn's disease and ulcerative colitis.

Abstract
BACKGROUND AND AIMS Early prediction of the effect of vedolizumab (VDZ) in inflammatory bowel disease (IBD) is of paramount importance to guide clinical decisions. This study assessed whether early fecal calprotectin (FC) can predict endoscopic response and histologic remission after VDZ initiation. METHODS This was a prospective study. Inclusion criteria were endoscopic inflammation and FC >100 µg/g. FC was determined at baseline and weeks 2, 4, 8 and 16. At week 16, endoscopies with ileal and colonic biopsies were performed. FC changes were assessed with Wilcoxon Rank Sum tests. ROC statistics were used to assess the diagnostic accuracy of FC. RESULTS In total, 45 patients [27 Crohn's disease (CD), 16/2 ulcerative colitis (UC)/IBD-unclassified] [40% males, median age 39 (28-51) years] were included. Week 16 endoscopic response and histologic remission rates were 58% and 33%. A median 37% decline in FC at week 2 was observed only in endoscopic responders, p = 0.025. FC <250 µg/g at week 8 predicted endoscopic response in both UC and CD (positive predictive value 100%), whereas absence of FC decline at week 8 corresponded with absence of endoscopic response in CD [negative predictive value (NPV) 82%] and absence of histologic remission in both UC and CD (NPV 90%). CONCLUSION The onset of a decline in FC as early as week 2 is associated with endoscopic response to VDZ induction. FC <250 µg/g at week 8 is associated with endoscopic response, whereas absence of FC decline at week 8 is associated with absence of both endoscopic response and histologic remission. FC levels 8 weeks after the start of VDZ could be used to guide clinical decisions and might substitute for endoscopic response evaluation.

Abstract
BACKGROUND AND AIM The association of fecal calprotectin (FC) and endoscopic response in inflammatory bowel disease patients during vedolizumab (VDZ) treatment is largely unknown. The aim of this study is to assess the diagnostic value of FC to predict endoscopic response. METHODS Patients with active endoscopic disease at baseline were included. Endoscopies and FC tests were performed at baseline and week 16. Patients with a confirmed endoscopic response at week 16 continued VDZ maintenance therapy, and endoscopy and FC tests were performed at week 52. Endoscopic response was defined as endoscopic Mayo score reduction of ≥ 1, SES-CD of ≥ 50%, or Rutgeerts' score of ≥ 1. Correlations were assessed using Spearman and receiver operating characteristic statistics. RESULTS A total of 114 patients, 46 ulcerative colitis and 68 Crohn's disease patients (44 men, median age 40 years), were included after the start of VDZ; 85% was anti-tumor necrosis factor alpha refractory. Endoscopic response was observed in 60 (53%) patients at week 16; the response sustained in 73% at week 52. FC decreased significantly from 819 at baseline to 154 μg/g at week 16. FC at weeks 16 and 52 were significantly correlated to (sustained) endoscopic response (r = -0.62 / r = -0.67, P < 0.001). FC < 200 μg/g indicates endoscopic response (area under the curve = 0.89, positive predictive value = 94%), whereas FC > 450 μg/g indicates endoscopic non-response after induction (negative predictive value = 83%). An increase in FC level of > 400 μg/g after induction indicates endoscopic loss of response (area under the curve = 0.97, negative predictive value = 96%). CONCLUSION This prospective study demonstrates a significant correlation between FC and endoscopic response to VDZ. FC < 200 μg/g prognosticate endoscopic response, and FC > 450 μg/g endoscopic non-response. An increase in FC of > 400 μg/g after induction indicates endoscopic loss of response. This simple FC algorithm may guide clinical decisions on the continuation and optimization of VDZ in inflammatory bowel disease patients.

Abstract
BACKGROUND As the reliability of fecal calprotectin (Fcal) remains debatable to detect endoscopic ulcerations in patients with pure ileal Crohn's disease (CD), we aimed to compare its performances with those observed in patients with colonic or ileocolonic location. METHODS Using a prospectively maintained database, we analyzed 123 CD patients with Fcal measurement and ileocolonoscopy performed within 1 month with no therapeutic intervention during this interval. Receiver operating characterstic curves (ROC) were used to determine the best Fcal threshold to detect endoscopic ulcerations, taking into account the clinical relevance and usual recommended indices. Sensitivity, specificity, and positive (PPV) and negative predictive values (NPV) were presented with 95% confidence intervals. RESULTS The mean Fcal level was significantly higher in patients with endoscopic ulcerations in the L1 group (P = 0.025) and the L2-L3 group (P < 0.001). Using ROC curves, Fcal >200 µg/g and Fcal >250 µg/g were the best thresholds to detect endoscopic ulcerations in the L1 group (sensitivity = 75.0, 95% CI, 47.6-92.7; specificity = 87.5, 95% CI, 67.6-97.3; PPV = 80.0, 95% CI, 51.9-95.7; and NPV = 84.0; 95% CI, 63.9-95.5) and in the L2-L3 group (sensitivity = 84.1 95% CI, 69.9-93.4; specificity = 74.4, 95% CI, 57.9-87.0; PPV = 78.7, 95% CI, 64.3-89.3, and NPV = 80.6, 95% CI, 64.0-91.8), respectively. We compared the AUC between L1 and L2-L3 groups, and no difference was shown (0.89 vs 0.84, respectively, P = 0.46). We also compared 2-by-2 sensitivity, specificity, PPV, NPV, and accuracy and we did not observe any significant difference. CONCLUSION Fecal calprotectin is highly effective to detect endoscopic ulcerations regardless of CD location but requires a lower cutoff value in patients with pure ileal involvement.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronically relapsing disease with a continuous need for proactive monitoring to decide appropriate treatments and follow-up strategies. To date, gastrointestinal endoscopy with histologic examination of biopsies and contrast-enhanced imaging are mandatory techniques for the diagnosis and the activity assessment of IBD. SUMMARY In recent decades, many research efforts in the IBD field have been placed on finding non-invasive and reliable biomarkers of disease burden that can be easily tested in body fluids without impacting the quality of life of patients. Unfortunately, the ideal biomarker is yet to be discovered and recent studies have investigated the possibility to increase the accuracy of such measurements by combining different markers. In this review, we provide an update about the current knowledge on biomarkers of intestinal inflammation in IBD, focussing on disease diagnosis, correlation with endoscopic findings, and prediction of relapse. We also summarize composite scores of clinical and laboratory markers that have been recently proposed in various scenarios of disease activity. Key Messages: To date, only C-reactive protein and faecal calprotectin can be considered reliable markers of disease activity with demonstrated utility in IBD management. The combination of different parameters has recently shown higher accuracy and might substitute single-marker approaches in the future of research and clinical practice.

Abstract
Fecal calprotectin has been widely studied in inflammatory bowel disease (IBD) under clinical and therapeutic settings. It showed a good correlation with clinical, endoscopic, and histologic findings. For these reasons, fecal calprotectin is currently one of the most useful tools in IBD care, both in diagnosis and in clinical management. The development of biologic drugs allowed a deeper control of disease, which sometimes reaches histological healing; this is associated with a reduced risk of relapses and complications. The management of IBD treatment is currently carried out with a treat-to-target approach, and mucosal healing is considered at present to be the optimal therapeutic target, but the future is going through histologic remission. Fecal calprotectin is probably the best marker of mucosal healing, but it is correlated also with histologic remission: moreover, it has been recently studied as a possible therapeutic target in the CALM study. We carried out a comprehensive literature review in order to evaluate the role of fecal calprotectin at present and in the future in the management of IBD therapies.

Serum Interleukin-6 and -8 as Predictors of Response to Vedolizumab in Inflammatory Bowel Diseases. J Clin Med 2020; 9:jcm9051323. [PMID: 32370274 PMCID: PMC7290461 DOI: 10.3390/jcm9051323] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 04/24/2020] [Accepted: 04/26/2020] [Indexed: 12/15/2022] Open
Abstract
Vedolizumab, a monoclonal antibody directed against integrin α4β7, is an effective treatment for inflammatory bowel diseases. However, a significant number of patients do not achieve steroid-free clinical remission in the first year of treatment. An early identification of these patients is one of the most important challenges for clinicians and offers the possibility of therapeutic optimization in order to personalize biological therapy. The aim of our study was to test the prediction ability of interleukin (IL)-6 and -8 of clinical response after 12 months of therapy with vedolizumab (T2). We performed a prospective, multicentre study in patients affected by inflammatory bowel disease by analysing cytokines level before starting vedolizumab (T0) and after 10 weeks of therapy (T1). In the overall cohort (n = 54), IL-8 decrease > 2.6 pg/mL in the first 10 weeks of therapy was able to predict clinical response (area under the curve (AUC) = 0.70, sensitivity = 66%, specificity = 75%, p = 0.010), negative C-reactive protein (CRP) (AUC = 0.71, sensitivity = 64%, specificity = 80%, p = 0.009) and calprotectin < 250 mg/kg (AUC = 0.69, sensitivity = 64%, specificity = 78%, p = 0.030) after 44 weeks of therapy. In patients with ulcerative colitis (n = 40), baseline IL-8 values > 8.6 pg/mL and a decrease of IL-6 values > 0.4 pg/mL from T0 to T1 were significant and independent predictors of clinical response after 12 months of vedolizumab therapy (odds ratio (OR) = 6.96, 95% CI 1.27–38.22, p = 0.026 and OR = 7.29, 95% CI 1.42–37.50, p = 0.017, respectively). In patients with Crohn’s disease (n = 14), baseline IL-8 values > 8.6 pg/mL and baseline IL-6 values > 1.6 pg/mL allowed the identification of patients achieving negative CRP at T2 (AUC = 0.75, sensitivity = 74%, specificity = 76%, p < 0.001) and patients with faecal calprotectin values < 250 mg/kg at T2 (AUC = 0.71, sensitivity = 78%, specificity = 63%, p = 0.004). In conclusion, our study highlights a potential clinical role of serum cytokine levels for the prediction of clinical and biochemical steroid-free response in patients treated with vedolizumab.

Inflamm Bowel Dis 2020; 26:643-652.

Abstract
BT-11 is a new oral, gut-restricted, first-in-class investigational drug for Crohn disease (CD) and ulcerative colitis (UC) that targets the lanthionine synthetase C-like 2 (LANCL2) pathway and immunometabolic mechanisms. Oral BT-11 was assessed for safety, tolerability, and pharmacokinetics (PK) in normal healthy volunteers (n = 70) in a randomized, double-blind, placebo-controlled trial. Subjects (n = 70) were randomly assigned to one of five single ascending dose cohorts (up to 100 mg/kg, p.o.) and three multiple ascending dose cohorts [up to 100 mg/kg daily (QD) for seven days, orally]. Safety and tolerability were assessed by adverse event (AE) reporting, vital signs, electrocardiogram, hematology, and clinical chemistry. BT-11 did not increase total or gastrointestinal AE rates, as compared with placebo, and no serious adverse events were observed. Oral BT-11 dosing does not result in any clinically significant findings by biochemistry, coagulation, electrocardiogram, hematology, or urinalysis as compared with placebo. Mean fecal concentrations of BT-11 increased linearly with increasing oral doses, with 2.39 mg/g at 7.7 mg/kg on day 7 of the multiple ascending dose (MAD). Analysis of plasma pharmacokinetics indicates that maximum systemic concentrations are approximately 1/6000th of observed concentrations in feces and the distal gastrointestinal tract. Fecal calprotectin levels were lower in BT-11 treated groups as compared to placebo. BT-11 significantly decreases interferon gamma positive (IFNγ+) and tumor necrosis factor alpha positive (TNFα+) cluster of differentiation 4 positive (CD4+) T cells and increases forkhead box P3 positive (FOXP3+) CD4+ T cells in colonic lamina propria mononuclear cells from patients with CD and patients with UC at concentrations of 0.01 µM when treated ex vivo. BT-11 treatment is well-tolerated with no dose-limiting toxicities up to daily oral doses of 100 mg/kg (16 tablets); whereas the efficacious dose is a single tablet (8 mg/kg). Phase II studies in CD and UC patients are ongoing.

Abstract
AIMS Vedolizumab (VDZ) prevents migration of activated leucocytes into inflamed mucosa. This study aimed to assess the patterns of serum cytokines in ulcerative colitis (UC) patients at baseline and during VDZ treatment, and to investigate their association with mucosal healing and clinical remission. METHODS We enrolled consecutive UC patients eligible for treatment with VDZ. A panel of serum cytokines were measured by fluorescence assay at weeks 0, 6 and 22. Colonoscopy was performed at baseline and week 54, to evaluate mucosal healing. The time trends of serum cytokines were analysed by log-linear mixed effect models, and their prognostic accuracy was evaluated by logistic regression. RESULTS Out of 27 patients included in the analysis, at week 54 mucosal healing was achieved in 12 (44%) and clinical remission in 17 (63%). Mucosal healing was associated with higher interleukin (IL)-8 values at baseline and with significant decrease in IL-6 and IL-8 levels over the first 6 weeks. A significant reduction of IL-6 and IL-8 levels over the first 6 weeks of treatment was associated also with clinical remission. Logistic models including, among the predictors, IL-6 and IL-8 at baseline and their changes over the first 6 weeks of treatment had 83% sensitivity and 87% specificity to predict mucosal healing, and 82% sensitivity and 90% specificity to predict clinical remission. CONCLUSION In UC patients, the serum patterns of IL-6 and IL-8 at baseline and over the first 6 weeks of treatment with VDZ could be useful to predict therapeutic outcome.

Abstract
Background Vedolizumab has been shown to induce clinical remission in patients with active ulcerative colitis. Treatment with anti-integrin vedolizumab leads to clinical remission in 16.9% and clinical response in 47.1% of cases after 6 weeks. However, in clinical practice, no decision to discontinue or continue vedolizumab therapy is made until 14 weeks at the earliest. Objective The aim of this study is to develop an algorithm for optimizing vedolizumab administration in patients with moderate-to-severe ulcerative colitis by calculating the probability of clinical response at week 14, on the basis of the data from week 6. Methods This is a prospective, single-arm, multicentric, noninterventional, observational study with no interim analyses and a sample size of 35 evaluable patients. Results The enrollment started in August 2018 and was still open at the date of submission. The study is expected to complete in September 2020. Conclusions The early identification of patients who are responding to an integrin antibody is therapeutically beneficial. At the same time, patients who are not responding can be identified earlier. The development of a therapeutic algorithm for identifying patients as responders or nonresponders can thus help prescribing physicians avoid ineffective treatments and stop these very early.
