About ImmunityBio
ImmunityBio is a vertically-integrated biotechnology company developing next-generation
therapies and vaccines 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. We are applying our 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.
Our platforms and their associated product candidates are designed to attack cancer and
infectious pathogens by activating and proliferating natural killer cells, and stimulating
CD8+ killer memory T cells in an orchestrated manner. The goal of this potentially best-in-class
approach is to generate immunogenic cell death thereby eliminating rogue cells from the body
whether they are cancerous or virally-infected. Our ultimate goal is to overcome the limitations
of current treatments, such as checkpoint inhibitors, and/or reduce the need for standard highdose chemotherapy in cancer by employing this coordinated approach to establish
immunological memory that confers long-term benefit for the patient.
Our proprietary platforms for the development of biologic product candidates include:
(i) antibody-cytokine fusion proteins, (ii) DNA, RNA, and recombinant protein vaccines, and
(iii) cell therapies. As of April 2024, our platforms have generated 9 first-in-human therapeutic
agents that are currently being or planned to be studied in 24 clinical trials across 12 indications
in liquid and solid tumors, including bladder, lung and colorectal cancers, and GBM. These
indications are among the most frequent and lethal cancer types for which there are high failure
rates for existing standards of care or, in some cases, no available effective treatment. We are
constantly monitoring and prioritizing clinical development based upon the availability of our
resources and the efficacy and market developments of our competitors products and product
candidates, among other factors.
Our lead biologic product Anktiva (N-803, or nogapendekin alfa inbakicept-pmln) is a novel
first-in-class agonist antibody-cytokine fusion protein. On April 22, 2024, the FDA approved
Anktiva plus Bacillus Calmette-Gu rin (BCG) for the treatment of adult patients with BCGunresponsive non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ, with or
without papillary tumors. Based on Anktiva s unique mechanism of action, we believe it could
potentially lead to the evolution of immunotherapy beyond T cells.
We have adopted a strategic position to be vertically-integrated and develop our products
according to the FDA s Good Manufacturing Practice standards for large-scale manufacturing,
even during Phase II clinical trial development. Biological upstream and downstream
manufacturing capabilities, with its attendant know-how and regulatory compliance for approval,
have long lead times. We have adopted an approach for preparedness to provide our vaccine,
immunotherapy, and cell therapy products at a global scale. As such, we have established our
own plants and have access to facilities on a global basis. We believe our plan to selectively
use third-party contract manufacturing organizations for certain of our assets at various stages,
coupled with internal development, will give us assurance that any products will have backup
manufacturing options.
