Pharmaceutical compositions are disclosed which comprise recombinant viruses containing a DNA fragment encoding a polypeptide recognized by a particular antibody H23, which recognizes a particular tumor antigen expressed on breast cancer cells. This antibody specifically binds to an epitope comprising a tandem repeat sequence of 20 amino acids comprised in a transmembrane form as well as a secreted form of the polypeptide specifically bound by antibody H23.

Pharmaceutical composition for the treatment or prevention of a malignant tumor

The application provides a polypeptide and a pharmaceutical composition which comprises said polypeptide, wherein said polypeptide is recognized by a particular antibody H23, which recognizes a particular tumor antigen expressed on breast cancer cells. This antibody specifically binds to an epitope comprising a tandem repeat sequence of 20 amino acids comprised in a transmembrane form as well as a secreted form of the polypeptides specifically bound by antibody H23.

A pharmaceutical composition which comprises a recombinant vaccinia virus containing a DNA fragment encoding for a polypeptide recognized by a particular antibody H23, which recognizes a particular tumor antigen expressed on breast cancer cells is provided. The antibody specifically binds to an epitope comprising a tandem repeat sequence of 20 amino acids comprised in a transmembrane form as well as a secreted form of the POLYPEPTIDES specifically bound by antibody H23.
