The present invention relates to anti-CD137
antigen-binding molecules that have an immune
cell-activating effect, cytotoxic activity, or
antitumor activity, while simultaneously having a reduced effect on non-tumor tissues, such as normal tissues, and producing fewer side effects, and methods for using the same. Anti-CD137
antigen-binding molecules that have an immune
cell-activating effect, cytotoxic activity, or
antitumor activity, while simultaneously having a reduced effect on non-tumor tissues, such as normal tissues, and producing fewer side effects, are provided by the discovery and production of CD137
antigen-binding molecules whose CD137-binding activity depends on various substances (e.g., small-molecule compounds) in tissues of interest. Methods for using the same, pharmaceutical formulations, and the like are also provided.An antigen-binding molecule is also provided, whose antigen-binding activity varies depending on the
small molecule compound, the method of preparation, and its uses.
