A natural match for the complexity of human disease.

Modern medicine struggles to keep pace with the emergence, mutation, and diversity of disease. The body’s natural defense system produces polyclonal antibodies against invaders such as viruses, allergens, bacteria, toxins, and other pathogens.

SAB Biotherapeutics has developed a first-of-its-kind therapeutic engine—unleashing the power of the body’s native biological defense system to produce immunotherapies that truly match and overpower the complexity, diversity, and evolution of human disease.

This new class of immunotherapies opens the door to new medicines that are safer, more effective, and longer lasting than current antibody therapies.

About featured image

The sophistication of science. The genius of nature.

Through remarkable genetic engineering, we've developed the DiversitAb™ platform to harness the native human antibody immune response. Our novel therapeutic engine can produce medicines—human polyclonal antibodies—for a broad array of pathogens to treat modern health challenges such as seasonal influenza, Type 1 diabetes, and cancers.

Broad therapeutic reach in autoimmunity, infectious disease, inflammation and oncology

Immunotherapies will never be the same.

No other immunotherapies so fully capture the power of the human humoral immune response with natural synergistic targeting to the complexity of disease. Our therapeutic engine is capable of rapidly generating fully human polyclonal antibodies at commercial scale, armed against targeted pathogens.
