Current strategies for the production of therapeutic mAbs include the use of mammalian cell systems to recombinantly produce Abs derived from mice bearing human Ig transgenes, humanization of rodent Abs, or phage libraries. Generation of hybridomas secreting human mAbs has been previously reported; however, this approach has not been fully exploited for immunotherapy development. We previously reported the use of transient regulation of cellular DNA mismatch repair processes to enhance traits (e.g., affinity and titers) of mAb-producing cell lines, including hybridomas. We reasoned that this process, named morphogenics, could be used to improve suboptimal hybridoma cells generated by means of ex vivo immunization and immortalization of antigenspecific human B cells for therapeutic Ab development. Here we present a platform process that combines hybridoma and morphogenics technologies for the generation of fully human mAbs specific for disease-associated human antigens. We were able to generate hybridoma lines secreting mAbs with high binding specificity and biological activity. One mAb with strong neutralizing activity against human granulocyte–macrophage colony-stimulating factor was identified that is now considered for preclinical development for autoimmune disease indications. Moreover, these hybridoma cells have proven suitable for genetic optimization using the morphogenics process and have shown potential for large-scale manufacturing.
