Symphogen is a biotechnology company located in Copenhagen, Denmark that produces recombinant polyclonal antibody drugs for disease treatment and prevention. Their three main areas of therapeutic research are immunoglobulin replacement, cancer, and infectious diseases. The company was founded in 2000 and has patents on a drug discovery platform called Symplex and a drug manufacturing platform called Sympress. Currently, ten drugs are being developed with rozrolimupab being the lead product. Wikipedia.

Patent
Symphogen | Date: 2017-04-19

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.


Patent
Symphogen | Date: 2016-11-14

The invention relates to humanized recombinant antibodies targeting the EGFR family receptors EGFR, HER2 and HER3, compositions comprising at least one humanized anti-EGFR antibody, at least one humanized anti-HER2 antibody and at least one humanized anti-HER3 antibody, and use of the antibody compositions for treatment of cancer. The invention also relates to the use of antibodies targeting multiple EGFR-family receptors to treat cancer (e.g., pancreatic cancer) and cancer that has acquired resistance to previous therapies.

The ERBB family of receptor tyrosine kinases has a central role in the tumorigenesis of many types of solid tumour. Various therapeutics targeting these receptors have been approved for the treatment of several cancers. Considerable preclinical data have shown that the administration of two inhibitors against an individual ERBB family member-particularly epidermal growth factor receptor (EGFR) or ERBB2-leads to markedly higher antitumour activity than the administration of single agents. This Opinion article describes the preclinical and clinical performance of these dual-targeting approaches, discusses the key mechanisms that mediate their increased efficacy and highlights areas for ongoing investigation. © 2013 Macmillan Publishers Limited.

The invention relates to a method for manufacturing an anti-RhD recombinant polyclonal antibody composition (anti-RhD rpAb). The method comprises obtaining a collection of cells transfected with a library of anti-RhD antibody expression vectors, wherein each cell in the collection is capable of expressing from a VH and VL comprising nucleic acid segment, one member of the library, which encodes a distinct member of anti-RhD recombinant polyclonal antibody composition and is located at the same site in the genome of individual cells in said collection. The cells are cultured under suitable conditions for expression of the recombinant polyclonal antibody, which is obtained from the cells or culture supernatant. Nucleic acid segments encoding the anti-RhD rpAb are introduced into the cells by transfection with a library of vectors for site-specific integration. The method is suitable for manufacturing anti-RhD rpAb, thereby making available a superior replacement of plasma-derived prophylactic and therapeutic immunoglobulin products.

The invention relates to humanized recombinant antibodies targeting the EGFR family receptors EGFR, HER2 and HER3, compositions comprising at least one humanized anti-EGFR antibody, at least one humanized anti-HER2 antibody and at least one humanized anti-HER3 antibody, and use of the antibody compositions for treatment of cancer. The invention also relates to the use of antibodies targeting multiple EGFR-family receptors to treat cancer (e.g., pancreatic cancer) and cancer that has acquired resistance to previous therapies.


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 have shown 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.


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 analyses 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.
