Chronic urticaria is a disease manifested by a pruritic rash lasting longer than 6 weeks that may severely affect quality of life and daily function. Chronic urticaria can be further divided into chronic spontaneous urticaria which appears without a trigger and chronic inducible urticaria which evolves following distinct physical triggers. These two clinical manifestations could coexist in the same patient. The pathogenesis of chronic urticaria is not fully elucidated, although it is considered an autoimmune disease in at least 50% patients that produce auto- IgG antibodies targeted against the high affinity Fc receptor and to a lesser extent against IgE itself...

Targeting plasma IgE by therapeutic mABs like Omalizumab (Xolair(®)) is current clinical practice for severe allergic conditions or other IgE related diseases like chronic urticaria. As an alternative to soluble IgE targeting, IgE supply can be lowered by targeting the Extracellular Membrane Proximal Domain (EMPD) of the IgE B cell receptor (BCR) present on IgE switched B cells. This ultimately leads to apoptosis of these cells upon IgE BCR crosslinking. Since tools to selectively assess the efficacy of IgE BCR crosslinking by IgE targeting antibodies are limited, a readily quantifiable cell model was developed that allows to specifically address IgE BCR crosslinking activity in vitro...

BACKGROUND: The Atopic Dermatitis Anti-IgE Paediatric Trial (ADAPT) is a trial to determine the clinical efficacy and safety of omalizumab for children with severe atopic eczema. This article describes the detailed statistical analysis plan for the ADAPT as an update to the published protocol and is submitted prior to knowing all outcomes. METHOD AND DESIGN: The ADAPT is a randomised, double-blind, placebo-controlled trial with a primary objective to determine whether anti-IgE reduces eczema severity as assessed by the validated eczema score (objective SCORAD) after 24 weeks of treatment in children with severe eczema...

OBJECTIVE: It is unknown whether Omalizumab effectiveness changes over the course of time. Our retrospective real-life study tried to analyze whether Omalizumab response may be influenced by treatment duration. METHODS: 340 severe asthmatics treated with Omalizumab for different periods of time were recruited. They were subdivided into 4 groups according to the Omalizumab treatment length: <12, between 12 and 24, between 24 and 60 and >60 months. Omalizumab treatment results (FEV1, exacerbations, ACT, SABA use, asthma control levels, medications used e and ICS doses) were compared...

Acute lung injury (ALI) is an early pathophysiologic change in acute respiratory distress syndrome and its management can be challenging. Omalizumab (Xolair™) is a recombinant DNA-derived, humanized antibody. OMZ-SPT is a polypeptide on the heavy chain of omalizumab monoclonal antibody. Here, we found that intramuscular administration of OMZ-SPT significantly improved survival and attenuated lung inflammation in female C57BL/6 mice suffering from lipopolysaccharide (LPS)-induced ALI. We also demonstrated that OMZ-SPT can inhibit expression of the inflammatory cytokines tumor necrosis factor-α, interleukin-1β and interleukin-6 by ELISA in mice suffering from LPS-induced ALI and a mouse macrophage line (RAW264...

The treatment of solar urticaria is regarded as difficult. In some cases good responses to the anti-IgE antibody omalizumab (Xolair®), approved for treatment of chronic spontaneous urticaria, have been reported. We report on a 50-year-old Caucasian woman who for the last 5 years has developed localized itching and stinging erythemas following exposure to sunlight accompanied sometimes by anaphylactic reactions. Oral antihistamines in three- to four-fold doses and a topical sun screen had been only partially effective in long-term use...

The anti-human immunoglobulin E (IgE) monoclonal antibody, omalizumab (Xolair®, Genentech, South San Fransisco, CA), is effective in the treatment of poorly controlled moderate to severe allergic asthma and chronic idiopathic urticaria. It acts by specifically binding to the constant domain (Cϵ3) of free human IgE in the blood and interstitial fluid. Although efficacious, use of omalizumab is limited due to restrictions on patient weight and pre-existing IgE levels, and frequent dosing (q2-4 weeks). A vaccine inducing anti-IgE antibodies has the potential for similar clinical benefits with less frequent dosing and relatively lower cost of goods...

BACKGROUND: Asthma and COPD are common airway diseases. Individuals with overlapping asthma and COPD experience increased health impairment and severe disease exacerbations. Efficacious treatment options are required for this population. Omalizumab (anti-IgE) therapy is effective in patients with severe persistent asthma, but limited data are available on efficacy in populations with overlapping asthma and COPD. METHODS: Data from the Australian Xolair Registry were used to compare treatment responses in individuals with asthma-COPD overlap with responses in patients with severe asthma alone...

BACKGROUND: Peanut oral immunotherapy is a promising approach to peanut allergy, but reactions are frequent, and some patients cannot be desensitized. The anti-IgE medication omalizumab (Xolair; Genentech, South San Francisco, Calif) might allow more rapid peanut updosing and decrease reactions. OBJECTIVE: We sought to evaluate whether omalizumab facilitated rapid peanut desensitization in highly allergic patients. METHODS: Thirty-seven subjects were randomized to omalizumab (n = 29) or placebo (n = 8)...

BACKGROUND: Omalizumab (Xolair) dosing in severe allergic asthma is based on serum IgE and bodyweight. In Australia, patients eligible for omalizumab but exceeding recommended ranges for IgE (30-1500 IU/mL) and bodyweight (30-150 kg) may still receive a ceiling dose of 750 mg/4 weeks. 62% of patients receiving government-subsidised omalizumab are enrolled in the Australian Xolair Registry (AXR). OBJECTIVES: To determine if AXR participants above the recommended dosing ranges benefit from omalizumab, and to compare their response to within-range participants...

Immunoglobulin E (IgE) was discovered in 1966 and was found responsible for immune defense against helminths, type I hypersensitivity and allergic diseases. IgE mediates allergic responses by binding to Fc receptors (the high affinity Fc-epsilon receptor I and the low affinity Fc-epsilon receptor II or CD23) expressed on tissue mast cells and blood basophils. This binding leads to degranulation and release of pro-inflammatory mediators. Considering the pivotal role of IgE in allergic diseases, antibodies against IgE potentiate an array of new therapeutic strategies and in this regard omalizumab (rhuMAb-E25, Xolair) has been developed as a monoclonal biologic drug to block serum IgEs...

A three-part license expansion for omalizumab (Xolair(®)), humanized anti-IgE antibody, was recently made in Japan for paediatric use, additional higher doses and revised dosing frequency in allergic asthma. The dosing level and frequency of omalizumab are guided by a dosing table based on the total serum IgE and bodyweight. Nonlinear mixed-effect pharmacokinetic (PK) and pharmacodynamic (PD) modeling and simulation techniques described the binding between omalizumab and its target IgE. The population PKPD analysis was conducted using data from the nine studies included originally in the European application of dosing table expansion together with three Japanese clinical studies to assess the influence of the ethnicity...

Acute infection with viral pathogens in the herpesviridae family can trigger acute urticaria, and reactivation of herpesviridae is associated with cutaneous urticarial-like syndromes such as drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DRESS). Reactivation of latent herpesviridae has not been studied systematically in chronic idiopathic/spontaneous urticaria (CIU). This review proposes that CIU is an inflammatory disorder with autoimmune features (termed 'CVU' for chronic viral urticaria), based on serology consistent with the hypothesis that reactivation of a latent herpesvirus or -viruses may play a role in CIU...

Omalizumab (Xolair®) is a recombinant humanized monoclonal antibody that selectively binds to human immunoglobulin E (IgE). Omalizumab is used to treat IgE-mediated diseases such as chronic idiopathic urticaria (CIU) and moderate to severe allergic asthma. In pre-marketing clinical trials in patients with asthma, anaphylaxis was reported in 3 of 3,507 (0.1%) patients. In post-marketing spontaneous reports, the frequency of anaphylaxis attributed to omalizumab use was estimated to be at least 0.2% of patients based on an estimated exposure of about 57,300 patients from June 2003 through December 2006...
