Abstract
OBJECTIVE Asthma is a major global disease affecting adults and children, which can lead to hospitalization and death due to breathing difficulties. Although targeted monoclonal antibody therapies have revolutionized treatment of severe asthma, some patients still fail to respond. Here we critically evaluate the literature on biologic therapy failure in asthma patients with particular reference to anti-drug antibody production, and subsequent loss of response, as the potential primary cause of drug failure in asthma patients. RECENT FINDINGS Encouragingly, asthma in most cases responds to treatment, including the use of an increasing number of biologic drugs in moderate to severe disease. This includes monoclonal antibody inhibitors of immunoglobulin E and cytokines, including interleukin 4, 5, or 13 and thymic stromal lymphopoietin. These limit mast cell and eosinophil activity that cause the symptomatic small airways obstruction and exacerbations. SUMMARY Despite humanization of the antibodies, it is evident that benralizumab; dupilumab; mepolizumab; omalizumab; reslizumab and tezepelumab all induce anti-drug antibodies to some extent. These can contribute to adverse events including infusion reactions, serum sickness, anaphylaxis and potentially disease activity due to loss of therapeutic function. Monitoring anti-drug antibodies (ADA) may allow prediction of future treatment-failure in some individuals allowing treatment cessation and switching therefore potentially limiting disease breakthrough.

Abstract
Tumor necrosis factor alpha (TNF- α) inhibitors are widely employed for the management of chronic inflammatory rheumatism. However, their usage carries significant risks, including site and infusion reactions, serious infections, malignancy, heart failure autoimmune and demyelinating disorders. These risks are comprehensively outlined in risk management plans (RMPs) associated with these molecules. RMP provides information on the safety profile of a medicinal product as well as the measures that will be taken to minimize risks; these are known as risk minimization measures. These measures are divided into routine measures related to elements, such as the summary of product characteristics, labeling, pack size, package leaflet, or legal supply status of the product, while additional measures may include educational programs, including tools for healthcare providers and patients, controlled access or pregnancy prevention programs, among others. Additional measures can consist of one or more interventions that need to be implemented in a sustainable way in a defined target group, while respecting the timing and frequency of any intervention and procedures to reach the target population. An evaluation of the effectiveness of these measures is required to determine whether or not an intervention has been effective. This comprehensive review offers an in-depth exploration of the current treatment, uses, and associated risks of TNF-α inhibitors. Additionally, it provides a detailed account of risk minimization measures and risk management practices while shedding light on their real-world implementation and effectiveness.

Development of a concise and reliable method for quantifying the antibody loaded onto lipid nanoparticles modified with Herceptin. J Immunol Methods 2023; 521:113554. [PMID: 37661049 DOI: 10.1016/j.jim.2023.113554] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 08/01/2023] [Accepted: 08/31/2023] [Indexed: 09/05/2023]
Abstract
Antibodies are essential components of the immune system with a wide range of molecular targets. They have been recognized as modalities for treating several diseases and more than 130 approved antibody-based therapeutics are available for clinical use. However, limitations remain associated with its efficacy, tissue permeability, and safety, especially in cancer treatment. Nanoparticles, particularly those responsive to external stimuli, have shown promise in improving the efficacy of antibody-based therapeutics and tissue-selective delivery. In this study, we developed a reliable and accurate method for quantifying the amount of antibody loaded onto lipid nanoparticles modified with Herceptin® (Trastuzumab), an antibody-based therapeutic used to treat HER2-positive cancers, using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) followed by silver staining. This method proved to be a suitable alternative to commonly used protein quantification techniques, which are limited by lipid interference present in the samples. Furthermore, the amount of Herceptin modified on the liposomes, measured by this method, was confirmed by Herceptin's antibody-dependent cell-mediated cytotoxicity activity. Our results demonstrate the potential of this method as a critical tool for developing tissue-selective antibody delivery systems, leading to improved efficacy and reduced side effects of antibody-based therapeutics.

Abstract
Several monoclonal antibodies have been approved by the Food and Drug Administration (FDA) to treat allergic disorders, including omalizumab, dupilumab, mepolizumab, reslizumab, benralizumab, tralokinumab and tezepelumab, and their indications continue to expand. Although the risks associated with these agents are overall low, hypersensitivity reactions have been described and are reported more frequently with increased use. We provide a comprehensive review of clinical features, diagnosis and management of hypersensitivity reactions attributed to these agents. We aim to provide useful information for the clinician managing hypersensitivity reactions to these monoclonal antibodies, as well as highlight the need for future research to address specific gaps in knowledge.

Abstract
The optimal use of many biotherapeutics is restricted by Anti-drug antibodies (ADAs) and hypersensitivity responses which can affect potency and ability to administer a treatment. Here we demonstrate that Re-surfacing can be utilized as a generalizable approach to engineer proteins with extensive surface residue modifications in order to avoid binding by pre-existing ADAs. This technique was applied to E. coli Asparaginase (ASN) to produce functional mutants with up to 58 substitutions resulting in direct modification of 35% of surface residues. Re-surfaced ASNs exhibited significantly reduced binding to murine, rabbit and human polyclonal ADAs, with a negative correlation observed between binding and mutational distance from the native protein. Reductions in ADA binding correlated with diminished hypersensitivity responses in an in vivo mouse model. By using computational design approaches to traverse extended distances in mutational space while maintaining function, protein Re-surfacing may provide a means to generate novel or second line therapies for life-saving drugs with limited therapeutic alternatives.

Abstract
Biologic agents have become an integral therapeutic option for practicing allergists-immunologists for the management of asthma, atopic dermatitis, chronic rhinosinusitis with nasal polyps, and various immunologic conditions. As these agents vary considerably from traditional small-molecule drugs, various adverse reactions have been noted. A different approach must be used to classify these reactions beyond the classic Gell-Coombs classification system as it does not capture many of the adverse events seen with biologic therapy. This article addresses the available literature on proposed classification systems and diagnostic modalities for adverse events associated with biologics and reviews each approved agent used frequently in allergy-immunology practice.

Abstract
BackgroundSevere asthma is a heterogeneous inflammatory disease driven by eosinophilic inflammation in the majority of cases. Despite biologic therapy patients may still be sub-optimally controlled, and the choice of the best biologic is a matter of debate. Indeed, switching between biologics is common, but no official guidelines are available and real-world data are limited.Materials and methodsIn this post hoc analysis of the Italian, multi-center, observational, retrospective study, ANANKE. Patients with severe eosinophilic asthma treated with benralizumab were divided in two groups based on history of previous biologic therapy (biologic-experienced [suboptimal response] vs naïve). Baseline clinical and laboratory characteristics were collected in the 12 months prior to benralizumab treatment. Change over time in blood eosinophils, annualized exacerbation rate (AER), asthma control (ACT), lung function and oral corticosteroid (OCS) use following benralizumab initiation were collected in the two groups.ResultsA total of 147 biologic-naïve and 58 biologic-experienced (34 omalizumab, 19 mepolizumab, and 5 omalizumab-mepolizumab) patients were enrolled. Biologic-experienced patients were more likely to be atopic and have a higher AER despite more frequent OCS use. Similar reductions in AER (>90% in both groups), OCS use (≥49% reduction in dosage and ≥41% able to eliminate OCS), ACT improvement (≥7 points gained in 48 weeks) and lung function (≥300 mL of FEV1 improvement in 48 weeks) were observed after benralizumab introduction within the two groups. There were no registered discontinuations of benralizumab for safety reasons.ConclusionIn this post hoc analysis, patients who were switched to benralizumab because of suboptimal control with a previous biologic therapy were more likely to be atopic and more often treated with omalizumab. Benralizumab is effective in both naïve patients and those previously treated with a biologic.

Abstract
Many pediatric rheumatic diseases can be safely managed with biologic therapy. Severe allergic reactions to these medications are uncommon. We report the case of a 2-year-old male with systemic-onset juvenile idiopathic arthritis and secondary macrophage activation syndrome (MAS), whose treatment was complicated by severe allergic reactions to biologics, including drug reaction with eosinophilia and systemic symptoms (DRESS)/drug-induced hypersensitivity reaction (DIHR) likely due to anakinra, and anaphylactoid reaction to intravenous tocilizumab. These required transition to canakinumab, cyclosporine, and corticosteroids, with later development of interstitial lung disease and MAS flare needing transition from canakinumab to tofacitinib, which led to disease control. Whether lung disease is a manifestation of DRESS/DIHR to canakinumab remains unclear. High index of suspicion of hypersensitivity reactions for timely diagnosis and drug discontinuation is critical, especially in patients with active disease who might be at increased risk of these adverse events.

Abstract
PURPOSE OF REVIEW The use of biologic therapies has risen exponentially over recent years, allowing for unprecedented disease control within numerous areas of Allergy/Immunology. With this expanded use, awareness and understanding of adverse reactions to biologic agents have also increased. RECENT FINDINGS Multiple biologic adverse reaction phenotypes have been described, but significant overlap in clinical features across phenotypes exists. Given considerable phenotypic overlap, a targeted testing approach may not always be clear, and more recent classifications focus on management decision making using tools of diagnostic challenges and rapid drug desensitizations, guiding clinicians in developing a management plan when the exact underlying mechanism is not clearly known. With increased clinical experience with omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab, tezepelumab, rituximab, and TNF-inhibitors, there is a growing appreciation to the spectrum and particularities of adverse reactions to these agents which are outlined in this review. Our understanding of the clinical presentation and management of adverse reactions to biologic medications encountered in Allergy/Immunology has grown. Opportunities remain to further define optimal diagnostic and management strategies for these reactions.
