The invention relates to the field of recombinant antibodies for use in human cancer therapy. More specifically the invention provides compositions or mixtures of antibodies capable of binding human EGFR. Antibody compositions with 3 or more antibodies showed synergy in reduction of proliferation of representative cancer cell lines. Advantageous results have also been obtained with a composition comprising two different chimeric anti-hEGFR antibodies which show a new mechanism of action based on rapid and efficient receptor internalisation, induction of terminal differentiation and subsequent tumour eradication in an animal model. The antibodies of the invention can be manufactured in one bioreactor as a polyclonal antibody.

Recombinant anti-epidermal growth factor receptor antibody compositions

Disclosed is an anti-orthopoxvirus recombinant polyclonal antibody comprising distinct members which in union are capable of binding at least three orthopoxvirus related antigens, a pharmaceutical composition comprising the antibody, and a method for its production. Also disclosed is a polyclonal cell line capable of producing the recombinant polyclonal antibody as therapeutic methods utilizing the polyclonal antibody. Finally, the invention also pertains to a method for screening for useful Vand Vpairs useful when preparing the polyclonal antibody.

Anti-orthopoxvirus recombinant polyclonal antibody

A method is disclosed for inducing cell-mediated immunity against cellular antigens. More specifically, the invention provides for a method for inducing cytotoxic T-lymphocyte immunity against weak antigens, notably self-proteins. The method entails that antigen presenting cells are induced to present at least one CTL epitope of the weak antigen and at the same time presenting at least one foreign T-helper lymphocyte epitope. In a preferred embodiment, the antigen is a cancer specific antigen, e.g. PSM, Her2, or FGF8b. The method can be exercised by using traditional polypeptide vaccination, but also by using live attenuated vaccines or nucleic acid vaccination. The invention furthermore provides immunogenic analogues of PSM, Her2 and FGF8b, as well as nucleic acid molecules encoding these analogues. Also vectors and transformed cells are disclosed. The invention also provides for a method for identification of immunogenic analogues of weak or non-immunogenic antigens.
