NantKwest and ImmunityBio Sign Collaboration Agreement for Joint Development, Manufacturing, Marketing, and Commercialization of COVID-19 Vaccine and Related Therapeutics

Aug 24, 2020

Both companies agree to share equally in costs relating to COVID-19 therapeutics and vaccine candidates globally; global net profits to be shared 60%/40% in favor of the company contributing the product

EL SEGUNDO and CULVER CITY, Calif., August 24, 2020– NantKwest, Inc. (Nasdaq: NK), a clinical-stage, natural killer cell-based therapeutics company, and ImmunityBio, a privately-held immunotherapy company, today announced the signing of a definitive agreement to jointly develop, manufacture, market, and commercialize therapeutics and vaccines for combating the COVID-19 pandemic.

Under the terms of the definitive agreement, the two companies agree to share equally the costs incurred after August 21, 2020 of development, manufacturing, marketing, and commercialization of the products each is developing related to COVID-19. Should a product be commercialized successfully, the companies have agreed to a 60-40 percentage split of net profits, with the larger share going to the company that developed the product. The agreement also details the structure of shared governance of the joint collaboration.

The two product candidates currently in development under the agreement are a mesenchymal stem cell (MSC) therapeutic from NantKwest, whose goal is to reduce the time a critically ill patient spends on a ventilator; and a COVID-19 vaccine product from ImmunityBio, which is anticipated to soon enter into a phase I clinical trial.

“The severity and global nature of the COVID-19 pandemic demands that researchers move rapidly and have the resources necessary to develop ways to fight this deadly virus,” said Patrick Soon-Shiong, Chairman and CEO of NantKwest and ImmunityBio. “The agreement strengthens the efforts of both companies on behalf of patients, while also ensuring each company will earn a fair share of the returns of a successful product.”

About ImmunityBio 

ImmunityBio, Inc. is a late-clinical-stage immunotherapy company developing next-generation therapies that drive immunogenic mechanisms for defeating cancers and infectious disease. The company’s immunotherapy platform activates both the innate (natural killer cell and macrophage) and adaptive (T cell) immune systems to create long-term “immunological memory.” This novel approach is designed to eliminate the need for high-dose chemotherapy, improve upon the outcomes of current CAR T-cell therapies, and extend beyond checkpoint inhibitors. 

ImmunityBio’s platform is based on the foundation of three separate modalities: antibody cytokine fusion proteins, synthetic immunomodulators, and second-generation vaccine technologies.

ImmunityBio’s lead cytokine infusion protein, a novel interleukin-15 (IL-15) superagonist complex (AnktivaÔ), has received Breakthrough Therapy and Fast Track Designations from the U.S. Food and Drug Administration (FDA) for BCG-unresponsive CIS non-muscle invasive bladder cancer (NMIBC). Other indications currently at registration-stage trials include BCG-unresponsive papillary bladder cancer, first  and second line lung cancer, triple-negative breast cancer, metastatic pancreatic cancer, recurrent glioblastoma, and soft tissue sarcoma in combination with the company’s synthetic immune modulator (Aldoxorubicin).

ImmunityBio is also developing therapies, including vaccines, for the prevention and treatment of HIV, influenza, and the coronavirus SARS-CoV-2 with its second-generation human adenovirus (hAd5) vaccine platform.

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.
