摘要:
The present invention concerns compositions and methods of use of T-cell redirecting complexes, with at least one binding site for a T-cell antigen and at least one binding site for an antigen on a diseased cell or pathogen. Preferably, the complex is a DNL™ complex. More preferably, the complex comprises a bispecific antibody (bsAb). Most preferably, the bsAb is an anti-CD3×anti-CD19 bispecific antibody, although antibodies against other T-cell antigens and/or disease-associated antigens may be used. The complex is capable of targeting effector T cells to induce T-cell-mediated cytotoxicity of cells associated with a disease, such as cancer, autoimmune disease or infectious disease. The cytotoxic immune response is enhanced by co-administration of interferon-based agents that comprise interferon-α, interferon-β, interferon-λ1, interferon-λ2 or interferon-λ3.
摘要(中):
本发明涉及使用T细胞重定向复合物的组合物和方法,其中至少一个T细胞抗原的结合位点和病变细胞或病原体上的抗原的至少一个结合位点。 优选地,复合物是DNL TM复合物。 更优选地,复合物包含双特异性抗体(bsAb)。 最优选地,bsAb是抗CD3×抗CD19双特异性抗体,尽管可以使用针对其它T细胞抗原和/或疾病相关抗原的抗体。 该复合物能够靶向效应T细胞以诱导与疾病如癌症,自身免疫疾病或感染性疾病相关的细胞的T细胞介导的细胞毒性。 通过共同施用包含干扰素-α,干扰素-β,干扰素-λ1,干扰素-λ2或干扰素-λ3的基于干扰素的试剂来增强细胞毒性免疫应答。
