Current therapeutic strategies to treat MC-mediated diseases aim to suppress MC activation by utilizing small molecule inhibitors or antibodies targeting specific signaling receptors on MCs. However, these strategies require chronic drug exposure, which have inherent limitations including increased patient burden and potential toxicity. Moreover, the redundancy between multiple signaling pathways concomitantly regulating MC activation can lead to insufficient MC suppression.OBJECTIVETo develop a novel therapeutic strategy using an aglycosylated anti-KIT monoclonal antibody, briquilimab, to deplete MCs via KIT signaling inhibition.METHODSInhibition of KIT by briquilimab was evaluated in vitro in KIT expressing cell lines and primary human MCs. Briquilimab safety, pharmacokinetics, and MC depletion were evaluated in non-human primates (NHPs).RESULTSBriquilimab potently blocks SCF ligand binding to KIT and inhibits SCF/KIT signaling and primary MC degranulation and survival, leading to MC apoptosis via PI3K/AKT pathway in vitro. Additionally, aglycosylation of briquilimab mitigates unwanted MC activation. In NHPs, single and multi-dose high, chronic exposure of briquilimab is well-tolerated with mild to moderate, but reversible adverse effects and effectively depletes various tissue MCs, such as lung, skin, and colon, in a dose-dependent manner.CONCLUSIONSBriquilimab effectively inhibits SCF/KIT signaling and induces MC apoptosis, leading to profound and durable MC depletion in NHPs, and may provide a safe and novel therapeutic option to treat MC-mediated diseases.","PeriodicalId":14936,"journal":{"name":"Journal of Allergy and Clinical Immunology","volume":"37 1","pages":""},"PeriodicalIF":14.2,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These guidelines were primarily intended for practicing gastroenterologists; therefore, we summarize their key recommendations for the allergy and immunology community. In addition, as the prevalence and health care burden of EoE continues to increase, the population affected primarily comprises allergic individuals, and less invasive monitoring techniques are on the horizon, we discuss the key means by which allergists can contribute to the diagnosis and management of EoE. In particular, allergists can participate in screening for subtle EoE symptoms among their allergy patients, assist in optimizing the management of other allergic comorbidities, provide education about elimination diets, and facilitate the monitoring of disease over time.
