GigaGen Inc., a biotechnology company advancing transformative antibody drugs for immune deficiencies, infectious diseases and checkpoint resistant cancers, and a subsidiary of Grifols, announced today it has entered into a contract with the U.S. Department of Defense’s (DOD) Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) to demonstrate the utility of its first-in-class recombinant human polyclonal antibody discovery platform against biological threats of interest to the DOD.

GigaGen Inc., a biotechnology company advancing transformative antibody drugs for immune deficiencies, infectious diseases and checkpoint resistant cancers, and a subsidiary of Grifols, announced today the publication of a research article titled, “GMP manufacturing and IND-enabling studies of a recombinant hyperimmune globulin targeting SARS-CoV-2,” in the international, peer-reviewed journal Pathogens. This work showcases for the first time the GMP (good manufacturing practice) manufacturing and IND (Investigational New Drug)-enabling studies of its new class of drugs, recombinant polyclonal antibodies, describing the company’s recombinant polyclonal product that targets SARS-CoV-2, GIGA-2050.

GIGA-2050 is comprised of more than 12,000 antibodies but produced from a single master cell bank (MCB). Prior to GIGA-2050, manufacturing methods for much smaller mixtures of recombinant antibodies often involved the creation of separate MCBs for each monoclonal antibody, followed by mixing the MCBs prior to manufacturing. GIGA-2050 material produced at scales ranging from 3L to 250L had high product quality and consistent yield and potency. Through in vivo studies, GIGA-2050 was shown to be safe and protective against SARS-CoV-2 infection.

GigaGen Inc., the leading innovator in massively high-throughput immune repertoire single-cell sequencing and protein expression, today announced that it has been awarded a $1.5 million Phase II grant from the National Institutes of Health (NIH). The Phase II grant was awarded through the NIH Small Business Innovation Research (SBIR) program in from the National Institute of Allergy and Infectious Diseases (NIAID). The grant supports development of natural repertoire recombinant intravenous immunoglobulin (rIVIG) “hyperimmunes” against common pathogens for patients with primary immune deficiency (PID).

SOUTH SAN FRANCISCO, Calif., July 14, 2021 (GLOBE NEWSWIRE) — GigaGen Inc., a biotechnology company advancing transformative antibody drugs for infectious diseases, transplant rejection and checkpoint resistant cancers, and a subsidiary of Grifols, announced today publication of research in bioRxiv entitled, “Lack of blocking activity in anti-CTLA-4 antibodies reduces toxicity, but not anti-tumor efficacy.” The publication describes the novel mechanism of action of its anti-CTLA-4 drug candidate, GIGA-564, selected due to its reduced checkpoint inhibition, which resulted in superior anti-tumor activity and lower toxicity in murine models compared to commercially available anti-CTLA-4 drugs.
