GigaGen Inc., a biotechnology company advancing transformative antibody drugs for infectious diseases, transplant rejection and checkpoint resistant cancers, announced today publication of a peer-reviewed article titled, “Affinity maturation of antibodies by combinatorial codon mutagenesis versus error-prone PCR,” in the peer-reviewed journal mAbs. The publication is available online here.

GigaGen’s newly published data details the technical foundation of its approach for the affinity maturation of monoclonal antibodies discovered via its leading single-cell microfluidic technology platform, Surge. Affinity maturation is commonly used for antibody optimization when developing new drugs. The company is leveraging this technology platform for the development of monoclonal antibodies with unique binding and affinity profiles against selected oncology targets.

David Johnson, Ph.D., MBA, co-founder and chief executive officer of GigaGen, commented, “Often, antibodies need to be further engineered through ‘affinity maturation’ to achieve the appropriate affinities and kinetics that translate into in vivo efficacy. While this process can be important for antibody drug development, there are no universally accepted protocols for efficient and high-performance antibody affinity maturation. Our study is one of the most thorough evaluations of affinity maturation methods ever published. We have used knowledge from our work to develop novel antibody therapeutics with unique profiles against selected oncology targets, such as CTLA-4, with the potential to result in enhanced efficacy and safety profiles versus current antibody drug alternatives.”
