Abstract

В настоящем изобретении предложены биспецифические антитела, которые связываются с CD3 и опухолевыми антигенами, а также способы их применения. В соответствии с определенными вариантами реализации биспецифические антитела согласно изобретению демонстрируют сниженные эффекторные функции и имеют уникальный профиль связывания в отношении Fc-рецепторов. Биспецифические антитела сконструированы так, чтобы эффективно индуцировать опосредованное Т-клетками уничтожение опухолевых клеток. В соответствии с определенными вариантами реализации в настоящем изобретении предложены биспецифические антигенсвязывающие молекулы, содержащие первый антигенсвязывающий домен, который специфически связывает человеческий CD3, вторую антигенсвязывающую молекулу, которая специфически связывает человеческий CD20, и Fc-домен, который связывает Fc-рецепторы со специфическим профилем связывания. В определенных вариантах реализации изобретения биспецифические антигенсвязывающие молекулы согласно настоящему изобретению способны ингибировать рост В-клеточных или меланомных опухолей, экспрессирующих CD20. Биспецифические антитела согласно изобретению применимы для лечения различных видов рака, а также других связанных с CD20 заболеваний и нарушений.The present invention provides bispecific antibodies that bind to CD3 and tumor antigens, as well as methods of using them. In accordance with certain embodiments, bispecific antibodies of the invention exhibit reduced effector functions and have a unique binding profile for Fc receptors. Bispecific antibodies are designed to effectively induce T cell mediated tumor cell killing. In accordance with certain embodiments, the present invention provides bispecific antigen binding molecules comprising a first antigen binding domain that specifically binds human CD3, a second antigen binding molecule that specifically binds human CD20, and an Fc domain that binds Fc receptors with a specific binding profile. In certain embodiments of the invention, the bispecific antigen binding molecules of the present invention are capable of inhibiting the growth of B cell or melanoma tumors expressing CD20. The bispecific antibodies of the invention are useful in the treatment of various cancers as well as other CD20-related diseases and disorders.
