Bispecific molecules for use in inducing antibody dependent effector cell-mediated cytotoxicity

摘要

Bispecific molecules comprising a non-immunoglobulin tumor cell specific ligand and an antibody which binds the Fc receptor of an effector cell at a site that is not inhibited by endogenous immunoglobulin are disclosed. The bispecific molecules can be used to induce a specific antibody dependent effector cell-mediated cytotoxicity against tumor cells, such as small cell lung carcinoma (SCLC) cells, either in vivo or in vitro.
