Patent number: 10221246Abstract: The present invention is directed to improved therapeutics against receptors within the EGFR/ErbB/HER family that more broadly interfere with multiple members of the HER family (pan-HER inhibition). More particularly, the invention is directed to the use of antibody compositions for human cancer therapy. In vitro studies have shown that the antibody compositions of the invention targeting multiple HER family receptors are superior to antibody compositions targeting only one HER family receptor.Type: GrantFiled: November 28, 2016Date of Patent: March 5, 2019Assignee: Symphogen A/SInventors: Mikkel Wandahl Pedersen, Ida K.

Patent number: 9163232Abstract: The invention relates to a method for manufacturing a recombinant polyclonal protein composition, in particular a recombinant polyclonal antibody composition. The method comprises obtaining a collection of cells transfected with a library of variant nucleic acid sequences, wherein each call in the collection is transfected with and capable of expressing one member of the library, which encodes a distinct member of a polyclonal protein that binds a particular antigen and which is located at the same single site in the genome of individual cells in said collection, wherein said nucleic acid sequence is not naturally associated with said cell in the collection. The cells are cultured under suitable conditions for expression of the polyclonal protein, which is obtained from the cells or culture supernatant. The present method is suitable for manufacturing recombinant polyclonal antibodies, thereby making available a superior replacement of plasma-derived therapeutic immunoglobulin products.Type: GrantFiled: December 19, 2008Date of Patent: October 20, 2015Assignee: Symphogen A/SInventors: John S.

Patent number: 9029091Abstract: The present invention provides a structural characterization platform that can be used to assess the stability of a polyclonal cell line during production, as well as batch-to-batch consistency of the final polyclonal products. The structural characterization platform is based on genetic analysis as well as protein characterization techniques that alone or in combination provides the necessary information to characterize the polyclonal cell line and final products. The collection of different homologous proteins to be analyzed with the platform techniques is for example a recombinant polyclonal antibody or a mixture of monoclonal antibodies.Type: GrantFiled: October 16, 2012Date of Patent: May 12, 2015Assignee: Symphogen A/SInventors: Lone Kjær Rasmussen, Torben Frandsen, Søren Kofoed Rasmussen, Peter Sejer Andersen

Patent number: 8663640Abstract: The invention relates to the field of recombinant antibodies for use in human cancer therapy. More specifically the invention provides the use of an antibody composition with two distinct non-overlapping binding specificities to human EGFR. The antibody composition is effecting in treating cancer following treatment with other anti-EGFR antibodies, whether the cancer shows progression during or following the prior treatment or not. The antibody composition can also be used for repeated treatment of recurrent tumors following first-line therapy with the antibody composition of the invention, as the composition does not lead to selection of resistant tumors. A further therapeutic use is the use of an antibody composition of the invention for treatment of cancer that is resistant to known anti-EGFR antibodies.Type: GrantFiled: August 27, 2009Date of Patent: March 4, 2014Assignee: Symphogen A/SInventors: Mikkel Wandahl Pedersen, Michael Kragh, Adam S.

Patent number: 8414896Abstract: 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.Type: GrantFiled: November 12, 2010Date of Patent: April 9, 2013Assignee: Symphogen A/SInventors: Mikkel Wandahl Pedersen, Lucilla Steinaa, Allan Jensen, Klaus Koefoed, Per-Johan Meijer, Robert Carlsson, Charles Pyke, Lars Sogaard Nielsen
