<b><i>Background:</i></b> Vedolizumab is a humanized immunoglobulin G1 monoclonal antibody, which binds to α4β7 integrin on T lymphocytes, thus disturbing the interaction with mucosal vascular addressin cell adhesion molecule 1 on the intestinal endothelial cells to interfere with lymphocyte trafficking to the gut. <b><i>Summary:</i></b> Vedolizumab is a safe and effective drug to induce and maintain clinical remission in patients with Crohn’s disease (CD) and ulcerative colitis (UC) in both clinical trials and real-world data. Various guidelines recommend vedolizumab as a first- or second-line treatment regimen for steroid-dependent, steroid, or immunomodulator refractory cases of UC and CD; however, it is more effective in anti-TNF-naive patients. The first head-to-head trial (VARSITY trial) comparing the efficacy of vedolizumab to adalimumab has shown better clinical remission and mucosal healing with vedolizumab. <b><i>Key Messages:</i></b> In this review, we have discussed guidelines recommendation of vedolizumab use, as well as its safety data, use in special population, in presence of extraintestinal complications, therapeutic drug monitoring, data from Asian patients, along with other evolving concepts. Because of its excellent safety data and low immunogenicity, vedolizumab is an impressive option for patients with prior malignancy and less chance of reactivation of tuberculosis; however, cost remains an issue.

Abstract Background Current therapeutic goals in inflammatory bowel disease (IBD) include not only the mere absence of symptoms but also the resolution of endoscopic lesions, so-called mucosal healing (MH), which has been related to better outcomes. Data regarding the achievement of MH with vedolizumab (VDZ) in real-life clinical practice is still scarce. Methods Retrospective cohort study was carried out in a tertiary hospital between January 2015 and April 2019 including patients with a basal colonoscopy showing activity and who achieved clinical remission under treatment with VDZ, defined by partial Mayo score &lt;2 for ulcerative colitis (UC) and Harvey–Bradshaw Index score (HBI) &lt;4 for Crohn’s disease (CD). Surveillance colonoscopy was performed along with the follow-up according to clinical practice. In UC patients, MH was defined as Mayo Endoscopic Subscore (MES) = 0; the endoscopic response was defined by a decrease in MES ≥1 point. In CD, MH was defined by achievement SES-CD = 0–3 or Rutgeerts index i0; the endoscopic response was defined by a decrease of SES-CD of 50% or Rutgeerts index &lt;i2 with at least 1 point of decease compared with baseline. Results In total, 118 patients treated with VDZ were analysed, but only 45 met inclusion criteria with a median follow-up of 21 (IQR: 14–19) months. Surveillance colonoscopy was performed after a median time of 12 months (IQR:9–17) of treatment. MH achieved in 33/45 patients (73%): 17/23 CD patients (74%) and 16/22 UC patients (73%). The endoscopic response was achieved in 9 of the remaining 12 patients: 3/6 CD patients and 6/6 UC patients. Only 3 (7%) of patients included showed no endoscopic benefit at the time of surveillance endoscopy. In multivariate analysis, probability of not achieving MH was 75% in patients previously treated with immunosuppressants (ISS) (HR 0.25, 0.11–0.55 IC95; p = 0.001) and 60% in patients previously treated with anti-TNFα (HR 0.40, 0.18–0.90 95% CI; p = 0.026). Type of IBD, concomitant ISS, corticosteroid use at induction, baseline endoscopy score or duration of disease before VDZ treatment were not associated with the achievement of MH. Conclusion In our experience, most of the patients who achieve clinical remission with VDZ also achieve MH. Refractory patients were less likely to achieve MH despite having achieved clinical remission.

Background: Adalimumab (ADA) is an anti-tumor necrosis factor agent that has been shown to be effective in inducing and maintaining remission in adult patients with inflammatory bowel disease. The relationship between the ADA trough levels and clinical efficacy has been demonstrated, but there is variability in the definition of the most suitable range for its clinical applicability. Summary: A review of published studies during the last 5 years on ADA serum levels and its relationship with the clinical outcome was performed. The studies selected included 7 observational studies, a systematic review, a meta-analysis and a post hoc analysis of a clinical trial. The reported ADA levels that discriminate patients in clinical remission from those with active disease range from 4.5 to 8 µg/mL. This therapeutic range varies when considering endoscopic remission (7.5 to >13.9 µg/mL). Although the sample of patients with ulcerative colitis is small, a tendency to reach higher levels of ADA is observed in both clinical and endoscopic remission. Key Messages: The optimal therapeutic cut-off point of serum ADA levels ranges from 4.5–5 to 12 µg/mL, where ADA levels are associated with an adequate clinical monitoring of the disease during maintenance therapy. These ranges vary according to the target, suggesting levels of 4.8 µg/mL as the cut-off for clinical remission and levels ≥7.5 µg/mL for mucosal healing/endoscopic response. Controlled prospective studies are required to determine the optimal therapeutic interval of ADA serum levels both as induction and as maintenance therapy.

Neutrophils have been found to play an important role in the pathogenesis of inflammatory bowel disease (IBD), and anti-TNF-α mAb (i.e., infliximab) therapy is demonstrated to be effective in the induction of clinical remission and mucosal healing in these patients. However, how anti-TNF-α mAb regulates the functions of neutrophils is still unknown. Herein, we found that anti-TNF-α therapy significantly downregulated infiltration of neutrophils in inflamed mucosa of IBD patients. Importantly, anti-TNF-α mAb could inhibit neutrophils to produce proinflammatory mediators, such as ROS, calprotectin, IL-8, IL-6, and TNF-α. These data indicate that TNF-α plays a critical role in the induction of mucosal inflammatory response, and that blockade of TNF-α modulates intestinal homeostasis through balancing immune responses of neutrophils.

Abstract Introduction Ontamalimab is a fully human immunoglobulin G2 monoclonal antibody against mucosal addressin cell adhesion molecule-1 in development for the induction and maintenance of clinical remission in patients with ulcerative colitis (UC). This study aimed to assess the long-term pharmacokinetics (PK) of ontamalimab in patients with UC, and the effects of concomitant medications on PK parameters. Methods A 12-week induction study (TURANDOT; NCT01620255) was performed to assess the PK, efficacy and safety of ontamalimab (7.5, 22.5, 75 and 225 mg subcutaneous [s.c.] every four weeks [Q4W]) in patients with UC. Individuals who completed the induction study were eligible for enrollment in an open-label extension (OLE) study (TURANDOT II; NCT01771809) to assess the long-term PK, efficacy and safety of ontamalimab (75 or 225 mg s.c. Q4W up to week 72). Population PK analyses were performed using nonlinear mixed-effects modelling. Exposure-response analyses were performed to assess the relationships between minimum concentration (Cmin,ss) of ontamalimab and clinical response, clinical remission and mucosal healing. The effect of concomitant treatments (used for ≥20% of treatment duration) on PK parameters was also evaluated. Results The PK population included 130 (39.8%) women and 197 (60.2%) men, of median age of 40 years. A 1-compartment model with linear elimination adequately described the PK of ontamalimab. Population estimates of apparent clearance (CL/F) and volume of distribution (V/F) were 0.00917 L/h (0.22 L/day) and 7.44 L, respectively. Albumin had a significant effect on the variability of CL/F. Individuals with albumin levels of 30 g/L and 47 g/L are expected to have CL/F values 44% higher and 23% lower, respectively, than a typical patient with an albumin level of 39 g/L. Anti-inflammatory agents affected CL/F, such that CL/F is expected to be 14% higher in patients receiving than not receiving these agents. Other medications including immunosuppressants, steroids and treatments for peptic ulcers and gastroesophageal reflux disease had no effect on CL/F. Weight was the only covariate that significantly affected V/F. The half-life of ontamalimab was 23.4 days. Concentrations of ontamalimab over 72 weeks in the OLE study were consistent with those observed in the 12-week induction study. Ontamalimab Cmin,ss was related to efficacy, such that at week 16 (week 28 in total including induction), patients with higher Cmin,ss values were more likely to have clinical response, clinical remission and mucosal healing than those with lower Cmin,ss. Conclusion The exposure to ontamalimab was sustained following prolonged treatment in patients with UC for up to 72 weeks. Higher ontamalimab exposure was associated with a higher probability of clinical response.
