Abstract
(EN) The present invention provides a multispecific antibody conjugate (i.e., a bispecific antibody conjugate), and a related composition, therapeutic method and use thereof. The antibody conjugate comprises a multispecific antibody coupled on a nano material, such as a bispecific antibody. The antibody conjugate can be used for regulating immune responses and treating or preventing diseases and disorders (such as cancers, autoimmunity diseases, pathogen infection, or inflammatory diseases).
(FR) La présente invention concerne un conjugué d'anticorps multispécifiques (c'est-à-dire un conjugué d'anticorps bispécifique), et une composition associée, un procédé thérapeutique et une utilisation de celui-ci. Le conjugué d'anticorps de l'invention comprend un anticorps multispécifique couplé à un nanomatériau, tel qu'un anticorps bispécifique. Le conjugué d'anticorps peut être utilisé pour réguler des réponses immunitaires et traiter ou prévenir des maladies et des troubles (tels que des cancers, des maladies auto-immunes, une infection pathogène ou des maladies inflammatoires).
(ZH) 本发明提供了一种多特异性抗体偶联物(如双特异性抗体偶联物)、及其相关的组合物、治疗方法和用途。所述抗体偶联物包含偶联于纳米材料上的多特异性抗体,例如双特异性抗体。所述抗体偶联物可用来调节免疫应答、治疗或预防疾病或病症(例如癌症、自身免疫病、病原体感染或炎性疾病)等。
