Abstract[English]
The present disclosure relates to monoclonal antibodies that specifically bind to thymic stromal lymphopoietin (TSLP) and methods for treating atopic dermatitis. The antibodies block TSLP interaction with its receptor complex, preventing downstream inflammatory signaling. Administration involves weekly loading doses followed by biweekly maintenance doses, achieving superior clinical efficacy with >90% reduction in disease severity. The antibodies demonstrate favorable pharmacokinetics with a 25-day half-life, low immunogenicity, and a well-tolerated safety profile. This disclosure also covers methods for evaluating treatment efficacy and safety in moderate to severe atopic dermatitis patients.[French]
La présente divulgation concerne des anticorps monoclonaux qui se lient de manière spécifique à la lymphopoïétine stromale thymique (TSLP) et des méthodes de traitement de la dermatite atopique. L'anticorps bloque l'interaction TSLP avec son complexe récepteur, empêchant une signalisation inflammatoire en aval. L'administration implique le chargement hebdomadaire de doses suivies par des doses d'entretien bihebdomadaire, ce qui permet d'obtenir une efficacité clinique supérieure avec > 90% de réduction de la gravité de la maladie. Les anticorps démontrent une pharmacocinétique favorable avec une demi-vie de 25 jours, une faible immunogénicité et un profil de sécurité bien toléré. La présente divulgation concerne également des procédés d'évaluation de l'efficacité de traitement et de la sécurité chez des patients atteints de dermatite atopique modérée à grave.
