Abstract
Bullous pemphigoid (BP) is an autoimmune blistering disease associated with anti-BP180 and anti-BP230 antibodies. The pathogenic action mechanism of immunoglobulin E (IgE) antibodies in BP has been studied since the 1970s, and IgE antibodies have gradually been confirmed as being important in BP; therefore, anti-IgE therapy may be a new option for the treatment of BP. Omalizumab, as an IgE monoclonal antibody, has been increasingly used clinically to treat BP in recent years. Here, we collected 35 papers investigating omalizumab for BP treatment in a total of 83 patients, and the vast majority of patients showed varying degrees of improvement after treatment, except for a small number of patients with poor clinical outcomes. The patients were then divided into three groups according to dosing frequency and number of doses. Statistical analysis indicated that dosing frequency had little effect on clinical efficacy. While the groups with different numbers of doses were evaluated, the results concluded that clinical efficacy was affected by the number of doses, but there was no positive correlation between the number of doses and clinical efficacy.

Abstract
Omalizumab is widely used in clinical practice; however, knowledge gaps in the dosage of omalizumab for children aged 2-6 years with moderate-to-severe persistent allergic asthma have been identified. The aim of this study was to explore dosing regimens for moderately-to-severely allergic pediatric patients aged 2-6 years. The physiologically-based pharmacokinetic (PBPK) model of omalizumab was developed and verified in adult patients, extrapolated to pediatric patients, and simulated for omalizumab by adding two observation chambers (free IgE and total IgE). The simulation results showed that the fold errors of the predicted and observed values of the area under the curve (AUC) and peak plasma concentration (Cmax ) were between 0.5 and 2.0, and the average folding error and the absolute average folding error values for all concentration-time data points were 1.09 and 1.48, respectively. The PBPK model combined with pharmacokinetic/pharmacodynamic analysis of omalizumab demonstrated that both the model-derived dose and the original dose could control the average free IgE of 2-6-year-old children with moderate-to-severe allergic asthma below 25 ng/mL, and some of the model-derived doses were lower. This conclusion provides a basis for the selection of dosage in clinical practice reference.

Abstract
Background Allergic rhinoconjunctivitis (ARC) is an allergic disease that is characterized by conjunctival and nasal symptoms such as edema and congestion of conjunctiva, rhinorrhea, sneezing, and blocked nose. Seasonal ARC (SARC) is usually induced by seasonal allergens and often occurs at specific times during the year. Traditional treatments of SARC include nasal corticosteroids, antihistamines, and mast cell membrane stabilizers. Biological agents such as omalizumab have also been proved effective in the treatment of SARC. Objectives We aim to certify the preventative efficacy of omalizumab for SARC and explore its influence factors. Methods Medical records of 64 SARC patients were retrospectively analyzed, and generalized linear models were used to analyze influence factors of efficacy of omalizumab. Results Compared with forepassed pollen season without omalizumab treatment, the combined symptom and medication score (CSMS) of ARC with pre-seasonal omalizumab was significantly lower (with omalizumab: 0.67[0.00,1.83], without omalizumab: 4.00[2.83,4.96], p<0.001, max score=6). Subgroup analysis was conducted to explore the influence factor of preventative efficacy of omalizumab. The CSMS with omalizumab treatment were not significantly different among different age, gender, dosage, number of injections, and injection date subgroups (p>0.05). Conclusion Pre-seasonal omalizumab treatment could significantly relieve SARC related symptoms and reduce medication use. This preventative efficacy would not be influenced by the dosage and number of injections of omalizumab. A single dose of 150mg omalizumab could achieve a satisfactory outcome.

Abstract
Urticaria and angioedema are very common. Management of chronic urticaria subtypes, which usually persist for many years, is challenging. Recent years have demonstrated that targeting IgE with antibodies provides a safe and efficient treatment approach. Whilst several anti-IgE antibodies have been developed, omalizumab is currently the only one approved for use. International and national guidelines recommend its use after failure of antihistamines at standard and increased dose. Whilst not yet approved, many new anti-IgE approaches are currently being investigated in pre-clinical studies or clinical trials. This non-systematic focused review summarizes current knowledge of omalizumab and other anti-IgE biologics in chronic urticaria using data extracted from PubMed, Google Scholar and clinical trial databases, clinicaltrials.gov and clinicaltrials.eu. For adults, there is good evidence from randomized clinical trials and real-world data that symptomatic treatment with omalizumab is efficacious and safe in chronic spontaneous urticaria (CSU), whereas evidence in chronic inducible urticaria (CINDU) and special populations is limited. Easy-to-use tools to identify non-responders and predict the required duration of treatment have not been established yet. Phase 2 b results of ligelizumab have not only demonstrated efficacy and safety but also superiority to omalizumab. Indeed, there is preliminary evidence that omalizumab non- or partial responders benefit from ligelizumab. Whereas further development of quilizumab was discontinued, other approaches, eg UB-221 or DARPins are under investigation. Anti-IgE treatment with omalizumab represents a landmark in the treatment of chronic urticaria, with and without angioedema, and there is light on the horizon suggesting success may come with various next-generation anti-IgE approaches.

Abstract
Several monoclonal antibodies (mAbs) (omalizumab, mepolizumab, reslizumab, benralizumab, and dupilumab) are currently approved for the treatment of severe asthma. They have complex pharmacokinetic profiles. These profiles are unique in that they are dependent on their structure as well as can be markedly influenced by the biology of their target antigen, but their general behaviour can still be considered a class property, similar to their endogenous IgG counterpart. They cannot be administered by oral route, have a slow distribution into tissue, are metabolized to peptides and amino acids in several tissues but are protected from degradation by binding to protective receptors (the FcRn), which explains their long elimination half-lives. Their clearance is nonlinear because of the saturation of the target-mediated elimination. Also anti-drug antibody (ADA) response and off-target binding, as well as their glycosylation pattern, can influence the pharmacokinetics of mAbs.

Abstract
Severe asthma defined as uncontrolled or refractory asthma despite adequate use of high dose of inhaled steroid and additional long acting bronchodilators is associated with a high risk of comorbidities, exacerbations and persistent asthma-related symptoms. It remains a significant health care problem and represents the majority of health costs due to asthma. A better understanding of the basic mechanisms of the disease has allowed identification of new phenotypes and endotypes and of some predictive biomarkers. In the meantime an increasing number of promising biologicals are commercialized or on development providing new hopes to achieve asthma control and decrease exacerbation rate without the use of systemic corticosteroid. The increasing number of highly expensive available molecules poses physicians a new challenge: the identification of "the good treatment for the good patient". This article discuss the different biological available or in development in the field of severe asthma based on their mechanism of action and target. One of the aims is to help clarify the clinical decision-making process taking in account both the phenotype/endotype of the patient and the characteristics of these new drugs.

Abstract
INTRODUCTION Asthma is a chronic inflammatory airway disease. It occurs in a 'severe' form in about 8-10% of asthmatic patients. In the last decade, the development of biological drugs (e.g. monoclonal antibodies) allowed to efficiently approach severe asthma. The current therapeutic targets available are mainly those related to TH2 inflammation. Areas covered: The main pharmacokinetic and pharmacodynamic characteristics of the monoclonal antibodies against IL-5, IL-5Ra, IL4-IL13, and IgE, that are currently marketed or understood for severe asthma are discussed in this paper. Expert opinion: The currently available biological drugs represent an excellent therapeutic add-on to traditional drugs, especially in replacing systemic corticosteroid therapies. The different pharmacokinetic and pharmacodynamic characteristics of the drugs, despite sometime sharing the same target, would allow a better personalization of the therapy, tailoring the treatment to the characteristics of the patient.

Abstract
INTRODUCTION Omalizumab is a monoclonal antibody that binds and inhibits free serum immunoglobulin E, a mediator involved in the clinical manifestations of allergic asthma. Evidence for its efficacy and safety in the treatment of moderate-to-severe allergic asthma is based primarily on studies in adolescents and adults. However, there is increasing evidence of its utility in children with allergic asthma aged 6-12 years. Areas covered: This article reviews efficacy, safety, and effectiveness of omalizumab in the treatment of moderate-to-severe allergic asthma in children aged 6-12 years in clinical trials and in studies in clinical practice. Pharmacoeconomic aspects of its use among this population and the positioning of omalizumab in pediatric asthma management guidelines are also discussed. Additionally, an algorithm for the management of poorly controlled severe pediatric asthma in children older than 6 years is proposed. Electronic databases, such as PubMed, were searched for terms Asthma and Omalizumab and for asthma management guidelines. Expert commentary: Add-on omalizumab is an effective maintenance therapy in children aged 6-12 years with poorly controlled moderate-to-severe allergic asthma treated with medium-high inhaled corticosteroids doses and inhaled long-acting β2-agonists. Omalizumab appears safe in children in both clinical trials and real-life setting and may be cost-effective.

Abstract
Respiratory diseases affect millions of people worldwide, and account for significant levels of disability and mortality. The treatment of lung cancer and asthma with therapeutic antibodies (Abs) is a breakthrough that opens up new paradigms for the management of respiratory diseases. Antibodies are becoming increasingly important in respiratory medicine; dozens of Abs have received marketing approval, and many more are currently in clinical development. Most of these Abs target asthma, lung cancer and respiratory infections, while very few target chronic obstructive pulmonary disease - one of the most common non-communicable causes of death - and idiopathic pulmonary fibrosis. Here, we review Abs approved for or in clinical development for the treatment of respiratory diseases. We notably highlight their molecular mechanisms, strengths, and likely future trends.

Abstract
OBJECTIVE To evaluate the long-term efficacy and safety of omalizumab in asthma in a real-life setting. SUBJECTS AND METHODS This 4-year observational study included 65 patients treated with omalizumab during clinic visits; treatment response was rated as excellent, good, and partial based on a modified physician's Global Evaluation of Treatment Effectiveness (mGETE) scale of emergency room visits (ERV), hospitalization, use of oral corticosteroids, inhaled corticosteroid (ICS)/long-acting β-agonist (LABA) dose, and short-acting β-agonist rescue. The following tests were done: forced expiratory volume in 1 s (FEV1) and the asthma control test (ACT). Measurements were performed 1 month before therapy and at 16 weeks, 1 year, and 4 years of treatment. Statistical analyses were done using the Wilcoxon signed-rank test, Spearman rank correlation, and McNemar χ2 test. RESULTS The dropout rate was 15 (18.5%): 8 nonresponders (10.0%); 2 patients died (2.5%), and 5 were lost to follow-up (6.25%). Treatment response was excellent in 35 (53.8%); good in 23 (35.4%), and partial in 7 patients (10.8%). The number of excellent responders increased from 35 (53.8%) at 16 weeks to 48 (73.8%) at the 4-year follow-up. The number of patients who did not require ERV improved from 0 to 59 (90.8%), and the lowest rate of hospitalization was 1 in year 4 (p < 0.001); patients who did not require courses of oral corticosteroids improved from 0 to 54 (83%). ICS/LABA dose significantly reduced from 65 (100%) to 25 (38.5%) after 4 years of treatment (p < 0.001); ACT scores significantly increased from 15 ± 3 at baseline to 23 ± 3 (p < 0.001) and FEV1 level from 55.6 ± 10.6 to 76.63 ± 10.34 at year 4. CONCLUSION In this study, omalizumab therapy resulted in better asthma control, and was effective and well tolerated as an add-on therapy for patients with moderate-to-severe asthma.

Abstract
Omalizumab has been approved for the treatment of recalcitrant chronic spontaneous urticaria (CSU). However, it remains unanswered whether omalizumab modifies a CSU course. We aimed to study a course of CSU after omalizumab treatment in an Asian population. Medical records of recalcitrant CSU patients who attended Siriraj Hospital between 2013 and 2017 were reviewed. All patients receiving omalizumab treatment were followed after the first injection for at least 1 year. Of 15 patients receiving omalizumab treatment, 11 patients (73.3%) responded well to 150 mg while the rest required 300 mg. The median follow-up period was 18 months (range, 13.5-25.3). Three patterns of response were proposed and measured: excellent (disease remission over than 6 months) was found in 20%; good (injection interval extended longer than 6 months) was found in 27%; and modest (frequently required injections) was found in 53%. The mean duration of complete remission was 33 weeks (range, 26-38). Two-thirds of patients had disease relapse and required omalizumab injections to control symptoms. The other third did not show relapses for at least 69 weeks of the follow-up period. After 1 year of treatment, Kaplan-Meier curves estimated that a higher percentage (86.7%) of recalcitrant CSU patients receiving omalizumab treatment would be free of symptoms (weekly Urticaria Activity Score = 0) without prednisolone and/or cyclosporin as compared with 42% of patients not receiving omalizumab treatment. In conclusion, patients seem to be easily and safely manageable with omalizumab. Prednisolone and cyclosporin could be discontinued in all patients. Further studies are needed to conclude whether omalizumab can exactly modify CSU.

Can the response to Omalizumab be influenced by treatment duration? A real-life study. Pulm Pharmacol Ther 2017; 44:38-45. [PMID: 28302544 DOI: 10.1016/j.pupt.2017.03.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2017] [Revised: 03/10/2017] [Accepted: 03/12/2017] [Indexed: 12/28/2022]
Abstract
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. RESULTS ACT, exacerbations, GINA control levels, ICS doses and SABA use were similar in all groups with different Omalizumab treatment durations. Using a linear regression model, corrected for all confounding variables, a higher significant positive increase in FEV1% in subjects treated for 12-24 (β = 9.49; p = 0.034) or 24-60 months (β = 8.56; p = 0.043) was found when compared with subjects treated for a shorter period. Treatment duration was positively associated with a step down of the other associated therapies (OR: 1.013; p = 0.019). This association was more relevant (OR: 4.167; p = 0.005) when we considered Omalizumab treatment duration >60 months compared to the shorter therapy. In particular, the percentage of subjects that were taking Montelukast, LABAs and oral corticosteroids was lower in the group treated with Omalizumab for a longer period of time. CONCLUSION In real-life, the positive Omalizumab response remained stable for over 60 months. Long term Omalizumab treatment may lead to a discontinuation of some associated medications and to a slowing down of FEV1 decline.
