Abstract: The invention relates to a method performed ex vivo for removal of tumor cells from intraoperatively collected blood salvage, to antibodies and scaffold proteins which mimic antibodies for use in said ex vivo method, to the use of said ex vivo method for removal of tumor cells from intraoperatively collected blood salvage followed by reintroducing the so obtained purified blood salvage or of concentrates of erythrocytes purified by said method to a patient from whom said intra-operatively collected blood was obtained, as well as to blood salvage or a concentrate of erythrocytes, both obtainable by said method for reinfusion to said patient.

Abstract: The present invention relates to methods for reducing or eliminating the non-specific release of a cytokine associated with a disease comprising administering at least one glucocorticoid and an immunostimulating antibody. Additionally, the present invention relates to a pharmaceutical composition that contains at least one immunostimulating antibody and at least one glucocorticoid.

Abstract: The invention describes the use of trifunctional bispecific and trispecific antibodies for destroying tumor cells which e.g. are disseminated intraperitoneally due to a surgical intervention, wherein the antibody is administered intraoperatively, preferably directly locally into the abdominal cavity.

Abstract: The invention describes the use of a pharmaceutical preparation containing a trifunctional bispecific and/or trispecific having the following properties: a) binding to a T cell; b) binding to at least an antigen on a tumor cell associated with malignant ascites and/or pleural effusion; c) binding, by its Fc portion (in the case of bispecific antibodies) or by a third specificity (in the case of trispecific antibodies), to Fc receptor-positive cells for the destruction of the tumor cells in the treatment of malignant ascites and/or pleural effusion.

Abstract: The invention describes the use of a pharmaceutical preparation containing a trifunctional bispecific and/or trispecific having the following properties: a) binding to a T cell; b) binding to at least an antigen on a tumor cell associated with malignant ascites and/or pleural effusion; c) binding, by its Fc portion (in the case of bispecific antibodies) or by a third specificity (in the case of trispecific antibodies), to Fc receptor-positive cells for the destruction of the tumor cells in the treatment of malignant ascites and/or pleural effusion.

Abstract: 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 CD 133; 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 CD 133 in a population of patients suffering from a tumor.

Abstract: The present invention refers to a method of treating tumor growth and metastasis in a mammal, the treating comprising administering allogeneic effector cells together with trifunctional bispecific or trispecific antibodies or a combination thereof having the following properties: a) binding to a T cell b) binding to at least one antigen on a tumor cell c) binding via their Fc portion in the case of trifunctional bispecific antibodies or via third specificity in the case of trispecific antibodies to Fc receptor positive cells; the antibodies redirecting the allogenic cells away from host tissues in order to substantially reduce or avoid a graft versus host disease.

Abstract: The invention describes the use of trifunctional bispecific and trispecific antibodies for destroying tumor cells which e.g. are disseminated intraperitoneally due to a surgical intervention, wherein the antibody is administered intraoperatively, preferably directly locally into the abdominal cavity.

Abstract: The invention relates to the time-staggered utilization of tumor cells in combination with intact, preferably heterologous antibodies for the immunization of humans and animals.
