  • Positioning Biologics in the Management of Moderate to Severe Crohn's Disease
    REVIEW CURRENT OPINION Positioning biologics in the management of moderate to severe Crohn’s disease Jana G. Hashash and Fadi H. Mourad Purpose of review Since there is a lack of head-to-head randomized controlled trials, little direction is provided from guidelines on the positioning of biologics for the treatment of Crohn’s disease (CD). This review utilizes comparative effectiveness and safety results from real-world data and network meta-analyses to inform clinical practice for positioning of biological therapies in the treatment of moderate-to-severe CD. Recent findings We summarize the results of studies pertaining to the identification of predictors for response to biologics in CD. Recently published studies about the management of moderate-to-severe CD are discussed and a positioning algorithm is proposed for the therapeutic approach of these patients. Summary Different classes of biologics are comparable with regards to safety and almost similar in effectiveness in the management of CD. There are certain clinical scenarios in which one biologic is more effective than another. For instance, patients with a more aggressive disease phenotype such as fistulizing disease would benefit from infliximab over other biologics, whereas in older patients at a higher risk for infectious complications, it may be more appropriate to use ustekinumab or vedolizumab over the anti-tumor necrosis factor (TNF) agents. More data pertaining to identifying predictors of response to the different available therapies and head-to-head comparison trials are needed to personalize our therapeutic approach of CD patients. Keywords biologics, Crohn’s disease, moderate-to-severe, positioning INTRODUCTION The medical management of patients with CD To guide the choice of treatment in patients with has changed over recent years.

  • Therapeutic Class Overview Immunomodulators
    Therapeutic Class Overview Immunomodulators Therapeutic Class Overview/Summary: This review will focus on oral and injectable immunomodulators. These agents are used for a variety of inflammatory and immunologic conditions which include: rheumatoid arthritis, psoriatic arthritis, plaque psoriasis, juvenile/systemic idiopathic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis, hidradenitis suppurativa, uveitis and several cryopyrin-associated periodic syndromes. Specific Food and Drug Administration (FDA)-approved indications for each agent are summarized in Table 1. Overall, these agents achieve their therapeutic effect via several different mechanisms of action. The majority of oral and injectable immunomodulators inhibit the effect of proinflammatory cytokines, specifically interleukins or tumor necrosis factor (TNF)-α. Interleukin (IL) inhibitors include anakinra (Kineret®), canakinumab (Ilaris®), ixekizumab (Taltz®), rilonacept (Arcalyst®), secukinumab (Cosentyx®), tocilizumab (Actemra®), and ustekinumab (Stelara®) while the TNF-α inhibitors are adalimumab (Humira®), adalimumab-atto (Amjevita®), certolizumab pegol (Cimzia®), etanercept (Enbrel®), etanercept-szzs (Erelzi®), golimumab (Simponi®, Simponi ARIA®), infliximab (Remicade®), and infliximab-dyyb (Inflectra®). Abatacept (Orencia®) is a T-cell activation inhibitor, tofacitinib (Xeljanz®) is a Janus kinase inhibitor, and vedolizumab (Entyvio®) is an α4-β7 integrin receptor antagonist.1-19 Table 1.

  • Vedolizumab Use After Failure of TNF-Α Antagonists in Children And
    Schneider et al. BMC Gastroenterology (2018) 18:140 https://doi.org/10.1186/s12876-018-0868-x RESEARCH ARTICLE Open Access Vedolizumab use after failure of TNF-α antagonists in children and adolescents with inflammatory bowel disease Anna-Maria Schneider1, Daniel Weghuber1, Benjamin Hetzer2*, Andreas Entenmann2, Thomas Müller2, Georg Zimmermann3,4, Sebastian Schütz3, Wolf-Dietrich Huber5 and Judith Pichler5 Abstract Background: Vedolizumab is safe and effective in adult patients with Crohn’s disease (CD) and ulcerative colitis (UC); however, data in children with inflammatory bowel disease (IBD) are scarce. Therefore, we evaluated vedolizumab use in a cohort of Austrian paediatric patients with IBD. Methods: Twelve patients (7 female; 7 CD; 5 UC), aged 8–17 years (median, 15 years), with severe IBD who received vedolizumab after tumour necrosis factor α antagonist treatment were retrospectively analysed. Clinical activity scores, relevant laboratory parameters, and auxological measures were obtained at infusion visits. Results: In the CD group, 1/7 patient discontinued therapy due to a severe systemic allergic reaction; 1/7 and 2/7 patients achieved complete and partial response, respectively, at week 14; and 3/7 patients discontinued therapy due to a primary non-response or loss of response. In the UC group, complete clinical remission was achieved at weeks 2, 6, and 14 in 2/5, 1/5 and 1/5 patients respectively; partial response was observed in one patient at week 2. CD activity scores did not significantly change from baseline to week 38 (median 47.5 vs. 40 points, p = 1,0), while median UC activity scores changed from 70 to 5 points (p < 0,001).

CD typically causes transmural inflammation of any part of the GI tract, which may result in the complications of strictures and fistulas. In contrast, UC is characterized by superficial inflammation with a variable degree of severity [2,3]. In distinction to CD, where involvement is segmental, inflammation in UC is continuous from the anal verge and is usually restricted to the lamina propria and epithelium of the colon [1,4,5]. Typical symptoms of both conditions include bloody diarrhea, abdominal cramps and fatigue.
