Stage of development at the beginning of the project: Discovery


PX’Therapeutics has developed “customized” immunization technologies and cell fusion in semi-solid media. Finally, the company has developped humanization strategies for recombinant therapeutic mAb. In a joint effort, Px’Therapeutics and genOway have worked on the generation of two genetically modified mouse models to improve the selection of high-affinity antibodies and enhance their therapeutic quality. The third partner, INSERM Unit 851 has developed and selected fully human antiviral mAb directed against dengue serotypes aiming to produce “in vivo pre-validated” functional mAb.


The HU’S-MAP project was aiming at developing broad antibody humanizationtechnologies and approaches through strong collaboration between biotechcompanies (Px’Therapeutics and GenOway) and academic laboratories (INSERMUnit 851). For this purpose, main activities were focused on production of partiallyhuman or full-human antibody by molecular biology, by generation of originalmouse models and by immortalization of human B lymphocytes.

PX’Therapeutics developed a subtractive immunization approach for weakly antigenic and/or rare epitopes. The cell fusion technology in semi-solid media stabilized low-secretor hybridomas. Finally, the humanization mAb procedure has speed up the manufacturing of therapeutic mAb. GenOway worked on the generation of two genetically modified mouse models based on replacement and insertion of a human gene or part of a gene of interest. INSERM Unit 851 has used the Epstein Barr Virus Immortalization technology to develop fully human anti-dengue mAb.
