PHARMACEUTICAL ANTIBODY COMPOSITIONS WITH RESISTANCE TO SOLUBLE CEA

摘要

The present invention relates to pharmaceutical compositions for the treatment of an epithelial tumor in a human, said pharmaceutical composition comprising an IgG1 antibody specifically binding to human CEA, wherein the variable region of said IgG1 antibody comprises at least (i) a CDR-H1 having the amino acid sequence "SYWMH" (SEQ ID NO: 29) and a CDR-H2 having the amino acid sequence "FIRNKANGGTTEYAASVKG" (SEQ ID NO: 28) and a CDR-H3 having the amino acid sequence "DRGLRFYFDY" (SEQ ID NO: 27) or (ii) a CDR-H1 having the amino acid sequence "TYAMH" (SEQ ID NO: 31) and a CDR-H2 having the amino acid sequence "LISNDGSNKYYADSVKG" (SEQ ID NO: 30) and a CDR-H3 having the amino acid sequence "DRGLRFYFDY" (SEQ ID NO: 27). Furthermore, processes for the production of said pharmaceutical compositions as well as medical/pharmaceutical uses for the IgG1 antibody molecules bearing specificities for the human CEA antigen are disclosed.
