摘要:
patent summary: "anti-cd3 antibodies, bispecific antigen binding molecules that bind to cd3 and cd20, and uses thereof". The present invention relates to CD3 binding antibodies and methods of use thereof. In certain embodiments, antibodies of the invention bind to high affinity human cd3 and induce human t cell proliferation. The invention includes antibodies that bind to cd3 and induce t-cell mediated elimination of tumor cells. In certain embodiments, the present invention provides bispecific antigen binding molecules comprising a first antigen binding domain that specifically binds human cd3 and a second antigen binding molecule that specifically binds human cd20. In certain embodiments, the bispecific antigen binding molecules of the present invention are capable of inhibiting the growth of cd20-expressing b-cell tumors. Antibodies and bispecific antigen binding molecules of the invention are useful for treating diseases and disorders in which an induced up-directed or induced immune response is desired and / or therapeutically beneficial. for example, the antibodies of the invention are useful for treating various cancers as well as other cd20-related diseases and disorders.resumo patente de invenção: “anticorpos anti-cd3, moléculas biespecíficas de ligação ao antígeno que se ligam à cd3 e cd20, e usos dos mesmos”. a presente invenção refere-se a anticorpos que se ligam à cd3 e métodos de uso dos mesmos. de acordo com certas modalidades, os anticorpos da invenção ligam-se à cd3 humana com alta afinidade e induzem a proliferação de célula t humana. a invenção inclui anticorpos que se ligam à cd3 e induzem a eliminação mediada por célula t de células tumorais. de acordo com certas modalidades, a presente invenção fornece moléculas biespecíficas de ligação ao antígeno compreendendo um primeiro domínio de ligação ao antígeno que especificamente se liga à cd3 humana e uma segunda molécula de ligação ao antígeno que especificamente se liga à cd20 humana. em certas mo
