Use of trifunctional bispecific antibodies for the treatment of tumors associated with CD133+/EpCAM+ cancer stem cells

摘要

Use of a trifunctional bispecific antibody having the following properties of: a) binding to a T cell; b) binding to EpCAM as tumor-associated antigen on a tumor cell wherein the tumor cell additionally carries the membrane bound glycoprotein CD133; c) binding by its Fc portion to Fc receptor-positive cells for the preparation of a pharmaceutical composition for the destruction of cancer stem cells carrying the tumor-associated antigen EpCAM and the membrane bound glycoprotein CD133 in a population of patients suffering from a tumor.
