- FDA has approved five of seven sections in a rolling submission required for a New Animal Drug Application (NADA) for Company’s antibody generating DiversitAb™ platform in Transchromosomic (Tc) Bovine™
- Announcement further solidifies SAB leading position in delivering, fully-human high-potency target-specific multi-epitope binding immunoglobulin (hIgG) antibody treatments without the need for human donors
SIOUX FALLS, S.D., May 09, 2023 (GLOBE NEWSWIRE) -- SAB Biotherapeutics (SAB, Nasdaq: SABS), a clinical-stage biopharmaceutical company with a novel immunotherapy platform that produces specifically targeted fully-human multi-epitope binding immunoglobulin (hIgG) antibodies, also known as fully-human polyclonal antibodies, without the need for human donors, today announced the U.S. Food and Drug Administration has approved five of seven sections required for the Company’s pending New Animal Drug Application (NADA) for the company’s antibody-generating platform in Transchromosomic (Tc) bovine.
SAB is in the process of completing the remaining two sections of the NADA. Upon formal acceptance of the seven-step safety and effectiveness evaluation, the company will use this approval in support of Biologics License Applications (BLAs) with the FDA Center for Biologics Evaluation and Research (CBER) for its hIgG antibody investigational drugs.
“SAB is the only company in the world progressing this kind of advanced genetic engineering to develop rapid, scalable production of highly potent, fully-human polyclonal IgG antibodies, without the need for human donors,” said Eddie J. Sullivan, Ph.D., co-founder, President, and Chief Executive Officer of SAB Biotherapeutics. “The FDA has an established regulatory pathway to review our cutting-edge science, and we are pleased to be making significant progress. This process is a one-time approval that will be applicable for all subsequent investigational products produced from the DiversitAb™ platform using our transchromosomic bovine. SAB is focused on a successful completion of NADA to rapidly pursue BLA approvals for our investigational therapeutics.”
SAB continues to work closely with the FDA’s Center for Veterinary Medicine (CVM) and CBER to establish a NADA approval for the Company’s Tc bovine-based antibody-generating platform. In following this regulatory pathway, SAB’s proprietary platform will be further protected from any potential future generic competition beyond the 12-year exclusivity timeframe typically granted to newly approved biologics. Other FDA approved human therapeutics for patients have successfully utilized the NADA process.
“The NADA process is complex and our progress in completing five out of seven sections further solidifies our leading position in delivering fully human multi-epitope binding antibody treatments without a need for human donors,” said Alexandra Kropotova, MD, Chief Medical Officer of SAB Biotherapeutics. “We have a clinically validated platform with a clear regulatory path which has been used to develop products that we’ve taken to Phase II and III clinical trials. Recent Breakthrough Therapy and Fast Track designations for one of our leading compounds further support our regulatory path that is well-established and de-risked. Few, if any, other companies have the same capability.”
SAB’s Tc Bovine are a unique and proprietary component of SAB’s DiversitAb™ platform that creates exponentially higher amounts of hIgG antibody treatments with preferential pharmacological properties compared to animal-derived or synthetic human monoclonal immunotherapies. Cows are ruminant animals that inherently have a more robust immune response than humans. This response is stimulated when an immunogen specific and exclusive to a target is introduced to SAB’s Tc Bovine and boosted further with a specialized formulation and strategy that maintains a high level of antibody production over an extended period of time. This technology enables batch-to-batch consistency of large amounts of diverse, high-titer, high-avidity hIgG antibodies, which lead to a nearly endless supply of high-potency therapeutics—without the need for human donors.
SAB is leveraging its DiversitAb platform to discover and develop product candidates with the potential to be first-in-class or best-in-class against complex targets to treat or prevent diseases with significant unmet medical needs. These include infectious respiratory and gastroenterological diseases, autoimmune disorders, and oncology. DiversitAb™ is a proven platform with recent regulatory validation, with the FDA granting both Fast Track designation and Breakthrough Therapy designation to SAB-176, an investigational therapeutic for Type A and Type B influenza illness in high-risk patients, including those who have anti-viral resistant strains. SAB also recently announced positive top-line results from the Phase 3 National Institutes of Health’s (NIH) ACTIV-2 clinical trial that assessed SAB-185 in non-hospitalized people with COVID-19 who were at high risk for severe outcomes with demonstrated efficacy against the Omicron variant.
