Abstract
INTRODUCTION Current therapeutic options for patients with ulcerative colitis comprise monoclonal antibodies against tumor necrosis factor (TNF), alpha4/beta7 integrin, and interleukin (IL)12/23 as well as small molecules such as tofacitinib, upadacitinib, ozanimod, and filgotinib. However, many patients fail to respond to these agents or have loss of response over time. Therefore, there is a large unmet clinical need for new therapeutic agents. AREAS COVERED Here, we review recent phase 2/3 studies in active ulcerative colitis and discuss preliminary data on the efficacy (clinical, endoscopic, and histologic remission) and safety of novel drugs including Janus kinase (JAK) inhibitors, IL23 blockers, integrin inhibitors, and S1P1R modulators. EXPERT OPINION We highlight the potential impact of these agents for the future therapeutic landscape of this disease with special emphasis on clinical impact, unmet needs, safety aspects, and advanced combination therapy.

The Dual Role of Neutrophils in Inflammatory Bowel Diseases. J Clin Med 2016; 5:jcm5120118. [PMID: 27999328 PMCID: PMC5184791 DOI: 10.3390/jcm5120118] [Citation(s) in RCA: 177] [Impact Index Per Article: 22.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2016] [Revised: 12/06/2016] [Accepted: 12/13/2016] [Indexed: 12/21/2022] Open
Abstract
Inflammatory bowel diseases (IBD), including Crohn’s disease and ulcerative colitis, are characterised by aberrant immunological responses leading to chronic inflammation without tissue regeneration. These two diseases are considered distinct entities, and there is some evidence that neutrophil behaviour, above all other aspects of immunity, clearly separate them. Neutrophils are the first immune cells recruited to the site of inflammation, and their action is crucial to limit invasion by microorganisms. Furthermore, they play an essential role in proper resolution of inflammation. When these processes are not tightly regulated, they can trigger positive feedback amplification loops that promote neutrophil activation, leading to significant tissue damage and evolution toward chronic disease. Defective chemotaxis, as observed in Crohn’s disease, can also contribute to the disease through impaired microbe elimination. In addition, through NET production, neutrophils may be involved in thrombo-embolic events frequently observed in IBD patients. While the role of neutrophils has been studied in different animal models of IBD for many years, their contribution to the pathogenesis of IBD remains poorly understood, and no molecules targeting neutrophils are used and validated for the treatment of these pathologies. Therefore, it is crucial to improve our understanding of their mode of action in these particular conditions in order to provide new therapeutic avenues for IBD.

Abstract
INTRODUCTION The aim of this systematic review (SR) and meta-analysis was to assess the efficacy and safety of vedolizumab in the treatment of Crohn's disease (CD). MATERIAL AND METHODS A systematic literature search was conducted in Medline/PubMed, Embase and Cochrane Library until 25 January, 2015. Included studies were critically appraised according to the PRISMA protocol. Assessment in specified subgroups of CD patients and meta-analysis with Revman software were performed. RESULTS Two randomized controlled trial (RCTs) were included in a meta-analysis for the induction phase of therapy: GEMINI II and GEMINI III. The clinical response was significantly higher for patients who received vedolizumab compared to placebo in the general population (risk benefit (RB) = 1.48; p = 0.0006) and in both analyzed subgroups: patients with previous failure of anti-TNFs treatment (RB = 1.51; p = 0.006) and patients naive to earlier anti-TNFs (RB = 1.41; p = 0.001). The clinical remission in the general population and subpopulation of TNF-antagonist naive patients was significantly higher for patients who received vedolizumab compared to placebo (RB = 1.77; p = 0.003; RB = 2.29; p = 0.0004; respectively). Meta-analysis for adverse events, serious adverse events (SAEs) and serious infections, revealed that vedolizumab was as safe as placebo in the induction phase of therapy. CONCLUSIONS The clinical response was significantly higher for patients who received vedolizumab in the general population and in both analyzed subgroups of patients. The clinical remission in the general population and subpopulation of TNF-antagonist naive patients was significantly higher for vedolizumab, but no significant differences were revealed in the subgroup of patients with previous TNF antagonist failure.

Abstract
BACKGROUND Vedolizumab (VDZ) demonstrated efficacy in Crohn's disease (CD) and ulcerative colitis (UC) in the GEMINI trials. Our aim was to evaluate the efficacy of VDZ at week 14 in inflammatory bowel disease in a multicenter cohort of patients. METHODS Patients at Massachusetts General Hospital and Brigham and Women's Hospital were considered for inclusion. VDZ (300 mg) was administered at weeks 0, 2, 6, and 14. Efficacy was assessed using the Harvey-Bradshaw index for CD, the simple clinical colitis activity index for UC and physician assessment, along with C-reactive protein and decrease of corticosteroid therapy. Clinical response was defined as decrease in Harvey-Bradshaw index ≥3 and simple clinical colitis activity index ≥3 and remission as Harvey-Bradshaw index ≤4, simple clinical colitis activity index ≤2 and physician assessment of response and remission. RESULTS Our study included 172 patients (107 CD, 59 UC, 6 inflammatory bowel disease-unclassified, men 48.3%, mean age 40 years and disease duration 14 years). Fourteen patients had ostomy and 9 ileoanal pouch, and only 35.5% fulfilled eligibility for the GEMINI trials. Previous treatment failures with ≥ 2 anti-TNFs occurred in 70.9%, one-third were on an immunomodulator and 46% systemic steroids at baseline. In CD, 48.9% and 23.9% and in UC, 53.9% and 29.3% had clinical response and clinical remission at week 14, respectively. Adverse events occurred in 10.5%. CONCLUSIONS VDZ is safe and well tolerated in refractory inflammatory bowel disease patients in a clinical practice with efficacy in UC and CD with responses similar to what was seen in clinical trials.

Abstract
AIM: To conduct a meta-analysis examining the effectiveness and safety of vedolizumab for the treatment of ulcerative colitis (UC).
METHODS: A search was conducted of MEDLINE, Cochrane, EMBASE, and Google Scholar on July 31, 2013. Inclusion criteria were: (1) Randomized controlled trial (RCT); (2) Patients treated for UC; and (3) Intervention was vedolizumab. The following information/data were extracted from studies that met the inclusion criteria: the name of the first author, year of publication, study design, patient demographic information, response rate, remission rate, and adverse events. The primary outcome was clinical response rate, and the secondary outcomes were clinical remission rate and serious adverse events. Odds ratio (OR) with 95%CI were calculated for each outcome.
RESULTS: Of 224 studies initially identified, three RCTs examining the use of vedolizumab meeting the inclusion criteria were included in the meta-analysis. All studies examined the use of vedolizumab at dosages ranging from 0.5 to 10 mg/kg body weight (one study used a standard dose of 300 mg). The follow-up periods were approximately 6 wk. The total number of patients in the intervention groups was 901, and in the control groups was 221. The mean age of the patients was approximately 41 years, and approximately half were males. The follow-up periods ranged from 43 d to 6 wk. The clinical response and remission rates were significantly higher for patients who received vedolizumab as compared to control patients (clinical response: OR = 2.69; 95%CI: 1.94-3.74, P < 0.001 and remission rate: OR = 2.72; 95%CI: 1.76-4.19, P < 0.001). Serious adverse events were not higher in patients that received vedolizumab.
CONCLUSION: This analysis supports the use of vedolizumab for the treatment of UC.

Abstract
Vedolizumab is an anti-inflammatory monoclonal antibody that exclusively targets the α4β7 integrin. We aimed to systematically review the efficacy and safety of vedolizumab for patients with inflammatory bowel diseases (IBDs). PubMed, EMBASE, and the Cochrane Library were searched up to May 2014. Randomized controlled trials examining the efficacy or safety of vedolizumab in patients with IBDs were eligible for inclusion. Data were extracted independently by 2 investigators and pooled using Review Manager 5.0 software (The Cochrane Collaboration, Copenhagen). Results were expressed as the relative risk (RR) with 95% confidence intervals (CIs). Six randomized controlled trials involving 2815 patients were eligible for inclusion. Vedolizumab was more effective than placebo for patients with ulcerative colitis and Crohn disease (CD) in clinical response (RR=1.82, 95% CI, [1.43, 2.31]; RR=1.46, 95% CI [1.18,1.81]) and clinical remission (RR=2.23, 95% CI [1.35, 3.68]; RR=1.71, 95% CI [1.25, 2.34]) during induction therapy. A superior effect was found during maintenance therapy in durable clinical/CD Activity Index-100 response (RR=2.22, 95% CI [1.62, 3.05]; RR=1.48, 95% CI [1.13, 1.94]) and clinical remission (RR=2.55, 95% CI [1.38, 4.70]; RR=1.15, 95% CI [0.75, 1.77]). However, vedolizumab may be associated with serious adverse events (RR=1.25, 95% CI [1.03, 1.52]) and nasopharyngitis (RR=1.56, 95% CI [1.08, 2.25]) for patients with CD. Vedolizumab was more effective than placebo as induction and maintenance therapy for IBDs, with an acceptable short-term safety profile, and achieving cure, although it may be associated with serious adverse events and nasopharyngitis for patients with CD.

Abstract
Inflammatory bowel disease (IBD) is an important cause of morbidity and mortality for millions of patients worldwide. Current treatment options include corticosteroids, 5-aminosalicylates, immunosuppressants, and TNFα antagonists. However, these are frequently ineffective in achieving sustained response and remission over time. At present, gastroenterologists lack safe and effective treatments if patients fail anti-TNF therapy. Vedolizumab is a promising new agent for IBD patients refractory to anti-TNF therapy. Vedolizumab is an integrin antagonist which is thought to act by reducing inflammation by selectively inhibiting leukocyte migration in the gut. Emerging evidence from clinical trials suggests a potential role for vedolizumab in both ulcerative colitis (UC) and Crohn's disease (CD), particularly in patients who have previously failed biological therapy. The safety profile of vedolizumab appears reasonable, possibly because it has a "gut-selective" mode of action, with no reported cases of progressive multifocal leukoencephalopathy, a condition which has been linked to another integrin antagonist, natalizumab. This review discusses the available evidence for integrin antagonists and their potential role in the management of IBD.

New targets for mucosal healing and therapy in inflammatory bowel diseases. Mucosal Immunol 2014; 7:6-19. [PMID: 24084775 DOI: 10.1038/mi.2013.73] [Citation(s) in RCA: 223] [Impact Index Per Article: 22.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2013] [Accepted: 08/16/2013] [Indexed: 02/06/2023]
Abstract
Healing of the inflamed mucosa (mucosal healing) is an emerging new goal for therapy and predicts clinical remission and resection-free survival in inflammatory bowel diseases (IBDs). The era of antitumor necrosis factor (TNF) antibody therapy was a remarkable progress in IBD therapy and anti-TNF agents led to mucosal healing in a subgroup of IBD patients; however, many patients do not respond to anti-TNF treatment highlighting the relevance of finding new targets for therapy of IBD. In particular, current studies are addressing the role of other anticytokine agents including antibodies against interleukin (IL)-6R, IL-13, and IL-12/IL-23 as well as new anti-inflammatory concepts (regulatory T cell therapy, Smad7 antisense, Jak inhibition, Toll-like receptor 9 stimulation, worm eggs). In addition, blockade of T-cell homing via the integrins α4β7 and the addressin mucosal vascular addressin cell adhesion molecule 1 (MAdCAM-1) emerges as a promising new approach for IBD therapy. Here, new approaches for achieving mucosal healing are discussed as well as their implications for future therapy of IBD.
