Anti-IgE therapy with omalizumab in asthma and allergic rhinitis.
The pharmacology, efficacy, dosage, adverse effects, and economics of anti IgE (omalizumab) are discussed. Omalizumab is the generic name for the human/murine chimeric (recombinant humanized) monoclonal IgG antibody. Anti-IgE prevents IgE from attaching to effector cells, and thereby blunts IgE-mediated inflammatory responses. After subcutaneous administration its absorption is slow, reaching p...
متن کاملAnti-IgE antibody therapy for Japanese cedar pollinosis: omalizumab update.
Seasonal allergic rhinitis (SAR) induced by Japanese cedar pollens is a substantial problem in Japan. Omalizumab, a novel humanized monoclonal anti-immunoglobulin E (IgE) antibody, has already been proven to reduce symptoms associated with SAR. To investigate the safety and efficacy of omalizumab in the treatment of patients with Japanese cedar pollen-induced SAR compared to placebo or anti-all...
متن کاملStructural basis of omalizumab therapy and omalizumab-mediated IgE exchange
Omalizumab is a widely used therapeutic anti-IgE antibody. Here we report the crystal structure of the omalizumab-Fab in complex with an IgE-Fc fragment. This structure reveals the mechanism of omalizumab-mediated inhibition of IgE interactions with both high- and low-affinity IgE receptors, and explains why omalizumab selectively binds free IgE. The structure of the complex also provides mecha...
متن کاملA review of anti-IgE monoclonal antibody (omalizumab) as add on therapy for severe allergic (IgE-mediated) asthma
Bronchial asthma is recognized as a highly prevalent health problem in the developed and developing world with significant social and economic consequences. Increased asthma severity is not only associated with enhanced recurrent hospitalization and mortality but also with higher social costs. The pathogenetic background of allergic-atopic bronchial asthma is characterized by airway inflammatio...
متن کاملInhibition of IgE and IgE/anti-IgE mediated responses in mast cells by Omalizumab
Results Omalizumab (10 ug/mL) inhibited IgE binding to LAD2 cells by 78% (P=0.007) compared to untreated control. Omalizumab (10 ug/mL) further blocked IgE-dependent upregulation of FcεRI expression by 90% (P=0.03). In addition, omalizumab removed FcεRI-bound IgE in a time-dependent manner; an effect that was detected as early as 24 hrs (57% removal; P<0.001) after addition of omalizumab result...
