ImmunityBio, Inc. ((IBRX), a leading immunotherapy company, today announced certain operational results following approval of the permanent J-code (J9028) in January 2025, as well as its financial results for the fourth-quarter and full year ended December 31, 2024.

With the issuance of the permanent J-code in January 2025, ImmunityBio has seen increased sales momentum supporting a trend of increases month-over-month as well as quarter-over-quarter, with February unit sales volume increasing 67% over January, and February and January unit sales combined exceeding unit sales achieved for all of Q4 2024. ImmunityBio earned net product revenue of approximately $7.2 million during the three-month period ending December 31, 2024, which represented an increase of 21% over the $6.0 million of net revenue earned during the third quarter of 2024.

The TICE BCG shortage was addressed with the FDA authorization to ImmunityBio of Expanded Access of the recombinant BCG (rBCG) supplied by the Serum Institute of India (SII). With the authorization in February 2025, over 60 sites in the United States are being activated to receive rBCG. The first patient dosed with rBCG in the United States is anticipated in March 2025. ImmunityBio anticipates that over 45,000 vials of rBCG will be available for the United States in 2025 to address the overall BCG shortage.

Global submission of marketing authorization applications (MAAs) for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors for ANKTIVA in combination with BCG to the Medicines and Healthcare products Regulatory Agency (MHRA) and to the European Medicines Agency (EMA) in the European Union (EU) have been accepted for review in February 2025.

In January 2025, the Company announced a collaboration and supply agreement with BeiGene, Ltd. (to be renamed to BeOne Medicines, Ltd.), a global oncology company, to conduct a confirmatory randomized Phase 3 clinical trial (ResQ201A-NSCLC), combining BeOne's tislelizumab, a PD-1 checkpoint inhibitor (CPI), and our ANKTIVA (nogapendekin alfa inbakicept-pmln) product. The Phase 3 ResQ201A-NSCLC study aims to confirm the efficacy and safety of combination ANKTIVA plus CPI therapy previously demonstrated in the QUILT 3.055 trial and provide evidence of the potential for these two immunotherapeutic agents to improve overall survival in patients with advanced or metastatic non-small cell lung cancer who have acquired resistance to immune CPI therapy.

In February 2025, ImmunityBio received an important authorization from the FDA designating ANKTIVA plus PD-L1 t-haNK as Regenerative Medicine Advanced Therapies (RMAT). The significance of a RMAT designation, which was established under the 21^st Century Cures Act, is to expedite the development and review of promising therapeutic candidates, including cell therapies, that are intended to treat, modify, reverse or cure a serious or life-threatening disease. RMAT designation includes benefits, such as early interactions with the FDA, including discussions on surrogate or intermediate endpoints that could potentially support accelerated approval and satisfy post-approval requirements, and potential priority review of a product's biologics license application (BLA). The RMAT designation was granted for ANKTIVA and CAR-NK (PD-L1 t-haNK) in combination with standard-of-care chemotherapy/radiotherapy indicated for:

• the reversal of lymphopenia and
• the treatment of multiply relapsed locally advanced or metastatic pancreatic cancer

"The first quarter of 2025 has been an inflection point for the Company with multiple milestones achieved. The approval of ANKTIVA and the permanent J-code, the trajectory of adoption of ANKTIVA by urologists for BCG unresponsive non-muscle invasive bladder cancer CIS, the authorization of expanded access of recombinant BCG to address the TICE BCG shortage, the acceptance of our global marketing submission to EMA and MHRA, the collaboration with BeOne for checkpoint inhibitor supply, and most importantly the potentially transformative RMAT designation by the FDA of ANKTIVA + PD-L1 t-haNK for the reversal of lymphopenia, all occurring at a rapid pace and demonstrating excellent execution are a testament to the strength of the organization and its ability to continue to execute on its ambitious growth plans for this year," said Dr. Patrick Soon-Shiong, Founder, Executive Chairman, Global Chief Scientific & Medical Officer of ImmunityBio. Dr. Soon-Shiong continued, "The RMAT designation positions ANKTIVA to be the backbone of our strategy for Immunotherapy 2.0 beyond checkpoints and the potential foundation of this first-in-class IL-15 receptor superagonist as a therapeutic cancer vaccine with over 100 participants enrolled in the Lynch Syndrome trial to evaluate cancer prevention in this high-risk population."

Fourth-Quarter Ended December 31, 2024 Financial Summary and Comparison to Prior Year Quarter

Product Revenue, Net

Product revenue, net increased $7.2 million during the three months ended December 31, 2024, as compared to the three months ended December 31, 2023. The increase was driven by sales of ANKTIVA after FDA approval in April 2024.

Research and Development Expenses

Research and development (R&D) expenses decreased $16.3 million to $35.2 million during the three months ended December 31, 2024, as compared to $51.5 million during the three months ended December 31, 2023. The decrease was primarily driven by lower research agreement expenses, inventory capitalization, less contract manufacturing organization activities, and lower consulting costs.

Selling, General and Administrative Expenses

Selling, general and administrative expense increased $8.6 million to $41.7 million during the three months ended December 31, 2024, as compared to $33.1 million during the three months ended December 31, 2023. The increase was due to higher costs related to post-commercialization activities and a litigation settlement.

Net Loss Attributable to ImmunityBio Common Stockholders

Net loss attributable to ImmunityBio common stockholders was $59.2 million during the three months ended December 31, 2024, compared to $233.4 million during the three months ended December 31, 2023. The reduction of loss was primarily driven by product revenue and changes in the fair value of related-party convertible notes and warrant liabilities.

About ANKTIVA

Cytokine fusion proteins, such as ANKTIVA, represent a novel class of biologics that improve immune responses by enhancing the therapeutic potential of cytokines and promoting lymphocyte infiltration at a site of disease. 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.

ANKTIVA is a first-in-class IL-15 receptor superagonist IgG1 fusion complex, consisting of an IL-15 mutant (IL-15N72D) fused with an IL-15Rα, which binds with high affinity to IL-15 receptors on NK, CD4+, and CD8+ T cells. This fusion complex of ANKTIVA, which confers stability and longer half-life than recombinant or native IL-15, mimics the natural biological properties of the membrane-bound IL-15Rα, 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. By activating NK cells, ANKTIVA overcomes the tumor escape phase of clones resistant to T cells without stimulating immunosuppressive T-reg cells and restores memory T cell activity with resultant prolonged duration of complete response. Further, by stimulating the release of interferon-γ, ANKTIVA restores MHC-I expression, making more tumor cells targets for T-cell killing. As evidenced by its ability to increase lymphocyte counts in healthy adults in Phase 1 testing, ANKTIVA also has the potential to rescue lymphopenia, which is associated with poor prognosis in cancer before treatment or as a consequence of chemo- or radiation therapy.

ANKTIVA was approved by the FDA in 2024 for use in the United States with BCG for the treatment of adult patients with BCG-unresponsive non-muscle invasive bladder cancer with CIS with or without papillary tumors. For more information, visit ImmunityBio.com (Founder's Vision) and Anktiva.com.
