SAB Biotherapeutics’ CMO Alexandra Kropotova to Deliver Presentation on Next Generation Biologics in Immunology at Biotech Showcase
SIOUX FALLS, S.D., January 9, 2023 (GLOBE NEWSWIRE) – SAB Biotherapeutics (Nasdaq: SABS), a clinical-stage biopharmaceutical company with a novel immunotherapy platform that produces specifically targeted, high-potency, high-avidity, fully-human polyclonal antibodies without the need for human donors, announced today that Alexandra Kropotova, MD, Executive Vice President and Chief Medical Officer, will deliver a presentation at the Biotech Showcase in San Francisco on Tuesday, Jan. 10 at 2:30 p.m. PST
Dr. Kropotova’s presentation, titled: Next Generation Biologics in Immunology: Solution for Complex Diseases, will discuss the latest innovations and treatment pathways in immunology, including an overview of SAB’s novel DiversitAb™ platform. DiversitAb™ is the only platform in the world that produces fully-human, broadly neutralizing, polyclonal antibodies utilizing transchromosomic cows. Dr. Kropotova will also present data from completed clinical trials that indicate SAB’s polyclonal antibody therapies can provide long-lasting efficacy against numerous highly mutating pathogens or multiple targets or pathways at once.
“SAB’s approach is to develop treatments designed to address multiple dysregulated pathways, multiple disease targets, and multiple epitopes in one powerful treatment,” said Dr. Kropotova. “SAB’s groundbreaking DiversitAb™ therapeutic platform and its promising pipeline developments in influenza, Clostridioides difficile, type 1 diabetes and other complex disease states with high unmet patient need is setting a promising new standard for immunology.”
