    • The present disclosure relates to bispecific antibodies that can bind to two or more different epitopes. For example, the bispecific antibodies described herein can bind to two or more different proteins, wherein at least two of the proteins are selected from C5a, C5b, a cellular receptor for C5a (e.g., C5aR1 or C5L2), the C5b-9 complex, and a component or intermediate of terminal complement such as C5b-6, C5b-7, or C5b-8. The bispecific antibodies described herein are useful for, e.g., inhibiting terminal complement (e.g., the assembly and/or activity of the C5b-9 complex) and/or C5a anaphylatoxin-mediated inflammation (e.g., C5a-mediated chemotaxis of inflammatory immune cells). Accordingly, the bispecific antibodies can be used in methods for treating a variety of complement pathway-associated disorders.
    • 本公开涉及可以结合两个或多个不同表位的双特异性抗体。 例如,本文所述的双特异性抗体可以结合两种或更多种不同的蛋白质,其中至少两种蛋白质选自C5a,C5b,C5a的细胞受体(例如C5aR1或C5L2),C5b-9复合物, 和末端补体的成分或中间体如C5b-6,C5b-7或C5b-8。 本文所述的双特异性抗体可用于例如抑制末端补体(例如,C5b-9复合物的组装和/或活性)和/或C5a过敏毒素介导的炎症(例如,C5a介导的炎性免疫细胞趋化性) 。 因此,双特异性抗体可用于治疗各种补体途径相关疾病的方法。

    • Disclosed herein are compositions and methods for screening for novel compounds that bind to polypeptides of therapeutic interest (e.g., polypeptides implicated in, or known to contribute to, the pathogenesis of human disease). In some embodiments, the compounds bind to a component of the human complement cascade such as human complement component C5. In some embodiments, the compounds so identified inhibit complement- mediated activity and are potential drug candidates for treating complement-associated disorders. This disclosure also provides compositions and methods for screening for novel compounds that inhibit complement-mediated activity and may be useful for identifying potential drug candidates for treating patients showing little or no response to the existing therapies for treating complement associated disorders.
    • 本文公开了用于筛选结合治疗感兴趣的多肽的新化合物的组合物和方法(例如涉及或已知有助于人类疾病发病机理的多肽)。 在一些实施方案中,化合物结合人补体级联的组分,例如人补体成分C5。 在一些实施方案中,如此鉴定的化合物抑制补体介导的活性,并且是治疗补体相关疾病的潜在药物候选物。 本公开还提供了用于筛选抑制补体介导的活性的新化合物的组合物和方法,并且可用于鉴定潜在的药物候选物,用于治疗对现有治疗补体相关疾病的治疗显示很少或没有反应的患者。
