Xencor Licenses ImmunoFilter Technology to Centocor Research and Development, Inc.; Proprietary Tool to Assess Protein Drug Candidates for Potential Immunogenicity.MONROVIA, Calif. -- Xencor, Inc., a biotherapeutics company developing protein and antibody therapeutics therapeutics Treatment and care to combat disease or alleviate pain or injury. Its tools include drugs, surgery, radiation therapy, mechanical devices, diet, and psychiatry. , today announced that it has granted Centocor Research and Development, Inc. a non-exclusive license to use Xencor's ImmunoFilter(TM) technology to evaluate the potential immunogenicity immunogenicity /im·mu·no·ge·nic·i·ty/ (-je-nis´it-e) the property enabling a substance to provoke an immune response, or the degree to which a substance possesses this property. of therapeutic proteins. ImmunoFilter is a predictive tool designed to enable Xencor and its partners to identify risk of future immunogenicity in antibody and other protein therapeutic candidates. Immunogenicity may reduce the therapeutic efficacy of a protein drug and may trigger potentially severe adverse events. Under the terms of the agreement, Xencor granted to Centocor a multi-year license to Xencor's ImmunoFilter data and software. Xencor will receive annual license fees from Centocor and Centocor will use the ImmunoFilter tools in-house to evaluate immunogenicity of therapeutic candidates. Additional financial terms were not disclosed. Xencor's ImmunoFilter tools were developed based on a proprietary immunochemical im·mu·no·chem·is·try n. The chemistry of immunologic phenomena, as of antigen-antibody reactions. im data set of peptide agretope binding to class II major histocompatibility complex major histocompatibility complex n.

("MHC MHC major histocompatibility complex. MHC abbr. major histocompatibility complex MHC major histocompatibility complex. ") proteins, a key determinant determinant, a polynomial expression that is inherent in the entries of a square matrix. The size n of the square matrix, as determined from the number of entries in any row or column, is called the order of the determinant. of recognition of antigens by the immune system immune system Cells, cell products, organs, and structures of the body involved in the detection and destruction of foreign invaders, such as bacteria, viruses, and cancer cells. Immunity is based on the system's ability to launch a defense against such invaders. . Capable of assessing potential immunogenicity for more than 95% of the U.S. population and based on empirical binding data, ImmunoFilter technology is the first predictive method to use direct experimental measurements to catalog the breadth of MHC-peptide interactions. "We are pleased to expand our relationship with Centocor to include a license to our proprietary ImmunoFilter technology, which is designed to assess the potential immunogenicity of protein drug candidates very early in the development process," said Bassil Dahiyat, Ph.D., President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Xencor. About ImmunoFilter(TM) Technology ImmunoFilter technology focuses on MHC binding of protein-derived peptides to predict the presence of class II major histocompatibility complex ("MHC") agretopes in protein sequence. Consisting of a database of proprietary immunochemical measurements and software, ImmunoFilter tools rapidly scan therapeutic protein candidates of interest. The ImmunoFilter database comprehensively addresses the high sequence diversity of MHC proteins among patient populations, and was generated from experimental measurements of peptide binding to a large set of class II MHC proteins. This provides nearly complete coverage of the MHC diversity present in the U.S. population. Xencor's ImmunoFilter technology was developed with funding from an Advanced Technology Program grant from the National Institute of Standards and Technology National Institute of Standards and Technology, governmental agency within the U.S. Dept. of Commerce with the mission of "working with industry to develop and apply technology, measurements, and standards" in the national interest. . About Xencor Xencor, Inc., engineers superior biotherapeutics using its proprietary Protein Design Automation(R) technology platform. The company is internally advancing both XPro(TM) protein therapeutic candidates and XmAb(TM) antibody drug candidates optimized for activity against biologically validated targets. Xencor's product development is led by a protein therapeutic drug candidate, XPro1595, for the treatment of arthritis and other rheumatic rheu·mat·ic adj. Relating to or characterized by rheumatism. n. One who is affected by rheumatism. rheumatic pertaining to or affected with rheumatism. disorders and antibody candidates for the treatment of cancer. With multiple partners, such as industry leaders Genentech, Roche, Centocor and MedImmune, Xencor is applying its suite of XmAb antibody Fc domains to improve antibody drug candidates for traits such as potency and sustained half-life. Xencor also develops therapeutic protein variants in collaboration with major pharmaceutical partners. For more information, please visit www.xencor.com. |
