CULVER CITY, Calif.—Nov. 12, 2024—ImmunityBio, Inc. (NASDAQ: IBRX) today announced its financial results for the third-quarter ended September 30, 2024.

•ANKTIVA® received a J-code (HCPCS Level II Code) in October 2024, effective January 1, 2025.

•ANKTIVA (FDA-approved and commercially available in the U.S. since May 2024) is now widely accessible to patients through commercial and government insurance programs (VA, DoD, Medicare). ImmunityBio has secured coverage for over 200 million medical lives through medical reimbursement policies.

•ImmunityBio achieved a net product revenue of approximately $6.0 million during the three months ended September 30, 2024, surpassing net product revenue of $1.0 million in the prior quarter and analyst estimates.

•ImmunityBio has extended the shelf life of ANKTIVA from two years to three years, with over 125,000 doses, providing ample product for the market and for clinical trials.

•ImmunityBio submitted to the Medicines and Healthcare products Regulatory Agency (MHRA) a Marketing Authorization Application (MAA) for ANKTIVA in the United Kingdom on November 1, 2024.

•ImmunityBio intends to submit to the European Medicines Agency (EMA) an MAA for ANKTIVA in the European Union (EU) in Q4 2024, covering 30 countries, including 27 in the EU and 3 in the European Economic Area (Iceland, Norway, Liechtenstein).

“The U.S. launch of ANKTIVA for NMIBC CIS continues to gain momentum, and we are pleased to see the clinical impact for patients,” said Richard Adcock, President and CEO of ImmunityBio. “Our permanent J-code has been issued by Centers for Medicare and Medicaid Services and will be effective January 1, 2025. Our submission of ANKTIVA for NMIBC CIS to the MHRA in the UK for potential approval demonstrates our plans for global expansion. Further, we anticipate an EU submission this quarter.”

“The response from the urologists and clinical practices with regard to the utility of ANKTIVA in NMIBC CIS has been gratifying. ImmunityBio’s clinical trial in BCG naïve NMIBC is enrolling well, and clinical sites have been expanded from the U.S. to multiple global locations. In the urology space, initial clinical trials of ANKTIVA are being designed for high-risk prostate cancer,” said Dr. Patrick Soon-Shiong, Executive Chairman, Global Chief Scientific & Medical Officer of ImmunityBio. “With the approval of ANKTIVA and the label of activating NK cells, CD4+ CD8+ T cells with memory T cells, ImmunityBio is focusing the regulatory development of ANKTIVA in BCG naïve bladder cancer and non-small cell lung cancer (NSCLC) patients who have failed checkpoint inhibitors.”

As of September 30, 2024, the Company had consolidated cash and cash equivalents, and marketable securities of $130.4 million.

Research and development (R&D) expenses increased $2.0 million to $50.4 million during the three months ended September 30, 2024, as compared to $48.4 million during the three months ended September 30, 2023. The increase was primarily driven by personnel-related and other R&D costs, partially offset by a decrease in external R&D expense driven by lower CMO fees and material purchases.

Selling, general and administrative expenses increased $4.1 million to $35.9 million during the three months ended September 30, 2024, as compared to $31.8 million during the three months ended September 30, 2023. The increase was primarily driven by higher salaries and benefits expense as a result of a reversal of discretionary compensation not paid in the prior period and an increase in consulting costs associated with commercial activities.

Net loss attributable to ImmunityBio common stockholders was $85.7 million during the three months ended September 30, 2024, compared to $95.6 million during the three months ended September 30, 2023.

The cytokine interleukin-15 (IL-15) plays a crucial role in the immune system by affecting the development, maintenance, and function of key immune cells—NK and CD8+ killer T cells—that are involved in killing cancer cells. By activating NK cells, ANKTIVA overcomes the tumor escape phase of clones resistant to T cells and restores memory T cell activity with resultant prolonged duration of complete response.

ANKTIVA is a first-in-class IL-15 agonist IgG1 fusion complex, consisting of an IL-15 mutant (IL-15N72D) fused with an IL-15 receptor alpha, which binds with high affinity to IL-15 receptors on NK, CD4+, and CD8+ T cells. This fusion complex of ANKTIVA mimics the natural biological properties of the membrane-bound IL-15 receptor alpha, delivering IL-15 by dendritic cells and drives the activation and proliferation of NK cells with the generation of memory killer T cells that have retained immune memory against these tumor clones. The proliferation of the trifecta of these immune killing cells and the activation of trained immune memory results in immunogenic cell death, inducing a state of equilibrium with durable complete responses. ANKTIVA has improved pharmacokinetic properties, longer persistence in lymphoid tissues, and enhanced anti-tumor activity compared to native, non-complexed IL-15 in-vivo.

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. Designated an FDA Breakthrough Therapy, ANKTIVA is the first FDA-approved immunotherapy for non-muscle invasive bladder cancer CIS that activates natural killer cells, T cells, and memory T cells for a long-duration response. The Company is applying its 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.
