NantKwest Expands NANT Cancer Vaccine Program With Additional Clinical Trials Announced Addressing Multiple Cancer Types Across All Stages of Disease

Jun 6, 2017

First Combination Off The Shelf NK And Adaptive Immunotherapy Trial To Be Initiated For Pancreatic, Lung, Breast, Colon, Melanoma, Sarcoma, Chordoma, Head And Neck, Non Hodgkin’s Lymphoma, Merkel Cell And Ovarian Cancers.

First Whole Genome, Transcriptomic, Proteomic (GPS Cancer) Informed Immunotherapy Trials Across All Tumor Types

Culver City, CA – June 6, 2017 – NantKwest and Nantworks today announced at the 2017 Annual American Society for Clinical Oncology meeting (ASCO) in Chicago, IL the expansion of the company’s existing NANT Cancer Vaccine program in pancreatic cancer ( NCT03136406) to target a number of additional tumor types.

The NANT Cancer Vaccine program is a personalized, molecularly-informed therapy guided by NantHealth’s GPS Cancer test that includes the simultaneous combination of off the shelf natural killer cells (NK) with the endogenous activation of dendritic, T cell and NK cells to more fully enhance the innate and adaptive immune system of cancer patients.

The NANT Cancer Vaccine is the first combination immunotherapy protocol formulated to include the novel delivery of metronomic, low-dose chemotherapy and radiation with molecularly-informed, tumor-associated antigen vaccines, together with NantKwest’s NK cell therapy, to induce immunogenic cell death while avoiding the ravages of toxic high dose chemotherapy.

By inducing immunogenic cell death and enhancing a patient’s innate and adaptive immune system, the NANT Cancer Vaccine is designed to attain a long-term, durable response in multiple cancer types with lower toxicity and higher efficacy in comparison with current standards of care.

“Current therapeutic approaches to the treatment of cancer are often inadequate to fully activate a patient’s immune response. Through the NANT Cancer Vaccine program, we believe we can help facilitate a paradigm shift in cancer care with the first clinical program formulated to incorporate low dose, metronomic chemotherapy and radiation, combined with molecularly-informed tumor associated antigens that are designed to activate dendritic and T cells by adenoviral and yeast vaccine vectors, together with both endogenous (IL-15) and exogenous (off the shelf) activation of NantKwest’s NK cell therapy,” said Patrick Soon-Shiong, Chairman and CEO of NantKwest.

Dr. Soon-Shiong continued, “In addition to the previously announced Pancreatic Cancer Vaccine, we are now actively working to initiate multiple clinical trials across a wide range of cancer types which include: Lung, breast, head and neck cancer, colon, melanoma, ovarian, urothelial, Hodgkins and non-Hodgkins lymphoma, sarcoma, and Merkel cell carcinoma, all based on a similar treatment protocol and designed to more fully harness the power of the immune system and improve cancer patient outcomes.”

About NANT Cancer Vaccine
The NANT Cancer Vaccine is the first combination immunotherapy protocol to orchestrate the delivery of metronomic low dose radiation and chemotherapy with molecularly informed tumor associated antigen vaccines and natural killer cells, to activate the innate and adaptive immune system and to induce immunogenic cell death. By inducing immunogenic cell death and protecting as well as enhancing the innate and adaptive immune system, the NANT Cancer Vaccine seeks to attain long-term sustainable remission of multiple tumor types with lower toxicity and higher efficacy than current standards of care.

About NantKwest Inc.
NantKwest (Nasdaq:NK) is a pioneering, next generation, clinical-stage immunotherapy company focused on harnessing the unique power of our immune system using natural killer (NK) cells to treat cancer, infectious diseases and inflammatory diseases. NK cells are the body’s first line of defense due to the innate ability of NK cells to rapidly identify and destroy cells under stress, such as cancer or virally-infected cells.

NantKwest’s unique NK cell-based platform, with the capacity to grow active killer cells as a biological cancer therapy, has been designed to induce cell death against cancer or infected cells by three different modes of action: (1) Direct killing using activated NK cells (aNK) that release toxic granules directly into the cell through cell to cell contact, (2) Antibody-mediated killing using haNKs, which are NK cells engineered to incorporate a high affinity receptor that binds to an administered antibody, enhancing the cancer cell killing effect of that antibody, and (3) Targeted activated killing using taNKs, which are NK cells engineered to incorporate chimeric antigen receptors (CARs) to target tumor-specific antigens found on the surface of cancer cells.

Our aNK, haNK and taNK platform addresses certain limitations of T cell therapies including the reduction of risk of serious “cytokine storms” reported after T cell therapy. 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 successfully administered as an outpatient infusion therapy without any reported severe side effects, 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 that include a Phase 2 trial for a rare form of melanoma and the planned initiation of a clinical trial of NK cells targeted to breast cancer, 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 therapies for treating cancer and infectious disease 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

Immunotherapies and cell therapies are key to future cancer treatments. Our investigational IL-15 superagonist, N-803, and NK-92®-engineered cells have demonstrated wide therapeutic potential across multiple tumor types, and, in clinical studies, have proven to be well-tolerated, making them ideal for clinical trial investigations.

Solutions for Research Scientists

Our NK-92® cell line provides a versatile bioanalytical testing solution that helps 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.
