NantWorks to Present Healthcare and Biotechnology Platforms at 36th Annual J.P. Morgan Healthcare Conference on January 9, 2018 in San Francisco, CA

Announces a Record 25 Letters of Authorization to Proceed with Clinical Trials Covering 12 Novel Biological Molecules in 20 Tumor Types

NantWorks, the parent organization of NantHealth NH and NantKwest NK announced today that Dr. Patrick Soon-Shiong (Chairman, CEO, and Founder) will present the current status of these companies and the overall ecosystem of NantWorks. Specific details will be presented regarding the current status of GPS Cancer^TM, including FDA filings and seminal patents issued covering tumor-normal analysis of DNA.

In addition, details will be presented regarding the record 25 letters of authorization covering 12 novel biological molecules tested across 20 tumor types within the NantWorks ecosystem of companies, of which 15 letters of authorization were received in 2017 for natural killer cells in combination with adenovirus, yeast, super agonist IL-15 and checkpoint inhibitors. The preliminary results of the first in human and safety studies of the NANT Cancer Vaccine will be released.

Presentation Time:

Time: January 9, 2018 at 5:00pm Pacific Time.

Location: 36^th Annual J.P. Morgan Healthcare Conference - Elizabethan A/B Breakout: Sussex Room

About NantKwest

NantKwest 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.

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.
