About NantKwest

NantKwest is an innovative clinical-stage immunotherapy company focused on harnessing the power of the innate immune system by using the natural killer cell to treat cancer, infectious diseases and inflammatory diseases.

NantKwest is uniquely positioned to implement precision cancer medicine, with the potential to change the current paradigm of cancer care. Natural Killer cells are ancient cells in the human body designed to recognize and detect cells under stress or infected. The NantKwest “off-the-shelf” activated Natural Killer (NK) platform is designed to destroy cancer and virally infected cells from the body. The safety of our NK cells as well as their activity against a broad range of cancers have been tested in multiple phase 1 clinical trials in the United States, Canada and Europe. In addition to our NK cells capability to be administered in the outpatient setting as an “off-the-shelf” living drug, it serves as a universal cell-based therapy without need for individualized patient matching. Moreover, our NK cell based platform has been bioengineered to incorporate chimeric antigen receptors (CARs) and antibody receptors to potentially further optimize targeting and potency in the therapeutic disease.

With the capacity to grow active killer cells as a biological cancer therapy, NantKwest’s NK cells have been designed to induce cell death against cancers and virally infected cells by multiple modes of action that include: Direct killing via innate recognition in which NK cells release toxic granules directly into the target (diseased) cell through cell-to-cell contact; Antibody-mediated killing using haNKs, which are NK cells engineered to incorporate a high binding affinity receptor that binds to an administered antibody, enhancing the cancer cell killing effect of that antibody; Chimeric Antigen Receptor directed killing using the taNK® platform, which includes NK cells engineered to incorporate chimeric antigen receptors (CARs) to target tumor-specific antigens found on the surface of cancer cells. All three modes of killing (innate, antibody-mediated, and Chimeric Antigen Receptor directed killing) using the t-haNK™ platform, which is an innovative combination of our haNK® and taNK® platforms in a single cell.

Our haNK®, taNK®, and t-haNK™ platforms have been designed to address certain limitations of T-cell therapies including the reduction of risk of serious “cytokine storms.” As an “off-the-shelf” therapy, NantKwest’s NK cells do not rely on a patient’s own often compromised immune system. In Phase 1 clinical trials in patients with late stage cancer, Nantkwest’s NK cells have been administered as an investigational outpatient infusion therapy without any reported severe side effects to date, even at doses of 10 billion cells.

By leveraging an integrated and extensive genomics and transcriptomics discovery and development engine, together with a pipeline of multiple, clinical-stage, immuno-oncology programs, we believe NantKwest is uniquely positioned to be the premier immunotherapy company and transform medicine by delivering living drugs in a bag and bringing novel NK cell-based therapies to routine clinical care.

How Can ImmunityBio Help You?

Solutions for Patients

Many cancer therapies, including radiation therapy, chemotherapy, CAR-T therapy, and B-cell immunotherapy, severely weaken the immune system—the human body’s most important natural disease-fighting weapon. But ImmunityBio creates targeted, personalized immunotherapies that are designed to strengthen the immune system and enable it to outsmart your disease.

Opportunities for Trial Investigators

The broad therapeutic potential and demonstrated safety of ImmunityBio’s immune-enhancing IL-15 superagonist Anktiva (N-803), engineered NK-92® cell-based therapies, and our next-generation adenovirus-vectored anti-cancer vaccines make them appealing therapeutics for testing by trial investigators who want to make a contribution to clinical cancer research. Interested clinicians and other are encouraged to contact ImmunityBio to find out how they may support discovery of future cancer treatments.

Tools for Research Scientists

Our NK-92® easy-to-maintain and highly cytotoxic natural killer cell line provides a versatile bioanalytical testing tool that can help researchers develop functional killing assays that are more consistent and reliable than donor blood and reporter gene assays.

ImmunityBio is continuously pursuing new immunotherapies designed to attack disease by enhancing the patient’s immune system, not weakening it.
