Described are multivalent multimeric antibodies comprising at least two binding sites specific for the human B cell marker CD19 and human Fc γ receptor III (CD16). Also described are polynucleotides encoding said antibodies as well as vectors comprising said polynucleotides, host cells transformed therewith and their use in the production of said antibodies. Finally, compositions are described comprising any of above mentioned antibodies, polynucleotides or vectors. The pharmaceutical compositions are useful for immunotherapy, preferably against B cell malignancies such as non-Hodgkin's lymphoma. |
