ImmunityBio is a vertically integrated commercial stage biotechnology company developing next-generation therapies that bolster the natural immune system to defeat cancers and infectious diseases. The Company’s range of immunotherapy and cell therapy platforms, alone and together, act to drive and sustain an immune response with the goal of creating durable and safe protection against disease. Designated an FDA Breakthrough Therapy, ANKTIVA is the first FDA-approved immunotherapy for non-muscle invasive bladder cancer CIS that activates NK cells, T cells, and memory T cells for a long-duration response. The Company is applying its science and platforms to treating cancers, including the development of potential cancer vaccines, as well as developing immunotherapies and cell therapies that we believe sharply reduce or eliminate the need for standard high-dose chemotherapy. These platforms and their associated product candidates are designed to be more effective, accessible, and easily administered than current standards of care in oncology and infectious diseases.

ImmunityBio, Inc. (formerly NantKwest, Inc.) is developing cell and immunotherapy products that are designed to help strengthen each patient’s natural immune system, potentially enabling it to outsmart the disease and eliminate cancerous or infected cells. The activation of the innate immune system is key to the development of immunological memory.
Over the last two decades, our founder and Executive Chairman Dr. Patrick Soon-Shiong has investigated mechanisms to activate the immune system to attack tumors that can otherwise evade and escape the body’s defense mechanisms. After inventing the world’s first protein nanoparticle drug, Abraxane, Dr. Soon-Shiong turned his focus to the next generation of immunotherapies. ImmunityBio was founded in 2014 to create innovative immunotherapies that address serious unmet needs in oncology and infectious diseases.
"At ImmunityBio, we envision a day when we no longer fear cancer but are able to conquer it, thanks to the biological wonder that is the human immune system. Our scientists are working to develop remarkable new therapies that harness that inherent power by amplifying both branches of the immune system, attacking cancerous or infected cells today while building immunological memory for tomorrow. The goal: to reprogram the patient’s immune system and treat the host rather than just the disease." -Dr. Patrick Soon-Shiong, Executive Chairman
