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.
