ImmunityBio, Inc. ((IBRX), a leading immunotherapy company, today announced that it has completed multiple submissions to the FDA including an sBLA for BCG-unresponsive NMIBC in papillary disease and an EAP for ANKTIVA^® (nogapendekin alfa inbakicept-pmln) for the treatment of lymphopenia.

Supplemental Biologics License Application (sBLA):

In Q1, ImmunityBio completed the submission to the FDA of an sBLA for the use of ANKTIVA plus BCG in BCG-unresponsive NMIBC in the papillary indication. Subject to regulatory approvals, the addition of the papillary indication expands the patient population benefiting from this therapy beyond the currently approved indication of bladder carcinoma in situ (CIS) with or without papillary disease and allows more patients to avoid the high morbidity and mortality associated with radical cystectomy. The data submitted to the FDA included efficacy results demonstrating durable complete remissions in patients with BCG unresponsive NMIBC papillary disease. In 88% and 82% of subjects, the probability of avoiding surgical removal of the bladder was achieved for as long as 2 and 3 years respectively, following treatment with ANKTIVA plus BCG. The mortality and morbidity associated with a radical total cystectomy is high and this long-term bladder sparing therapy has the potential to provide a significant benefit and quality of life to patients suffering from BCG unresponsive papillary disease.

In a pivotal study published in NEJM Evidence, BCG plus ANKTIVA resulted in a disease-free survival (DFS) rate of 55% at 12 months, 51% at 18 months, and 48% at 24 months in participants with papillary NMIBC. In addition, patients receiving the novel treatment achieved a 93% avoidance of cystectomy (surgical removal of the bladder) with a median follow up of 20.7 months. This combination immunotherapy wherein ANKTIVA rescues BCG efficacy, currently approved in the BCG-unresponsive carcinoma in situ (CIS) indication, may provide an effective therapeutic option for papillary patients who did not respond to BCG alone and face the prospect of a radical cystectomy. Papillary disease is estimated to be approximately 6-10 times more common than bladder cancer CIS, representing a large patient population that may benefit from ANKTIVA plus BCG.

Expanded Access Protocol for ANKTIVA in the Treatment of Lymphopenia:

The company also announced it has submitted to the FDA an EAP to make available ANKTIVA for the treatment of lymphopenia. Lymphopenia is the loss of natural killer cells and T cells, the very cells necessary to fight cancer. To date, no treatment exists to overcome lymphopenia which is induced by the cancer itself and by the standards of care including chemotherapy, radiation, steroids and checkpoint inhibitors. ImmunityBio received designation from the Agency for Regenerative Medicine Advanced Therapy (RMAT) for the indication of ANKTIVA to treat lymphopenia. The EAP, subject to authorization, would provide early access to patients and physicians desiring ANKTIVA in combination with standards of care.

Update of Product Revenue, Net Preliminary Results of Operations:

With the issuance of the permanent J-code (J9028) in January 2025, ImmunityBio has seen increased sales momentum supporting a trend of increases month-over-month as well as quarter-over-quarter, with March unit sales volume increasing 69% over February, and Q1 2025 unit sales exceeding unit sales achieved for all of FY 2024. ImmunityBio earned net product revenue of approximately $16.5 million during the three-month period ended March 31, 2025, which represented an increase of 129% over the $7.2 million of net revenue earned during the fourth quarter of 2024.

The amounts reported in this press release reflect the company's preliminary estimates based solely upon information available to it as of the date of this press release, and the amounts reported are not a comprehensive statement of its financial results or position as of March 31, 2025. Any actual amounts that the company reports in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, will be subject to its financial closing procedures and any final adjustments that may be made prior to the time its financial results for the period ended March 31, 2025 are finalized.

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. 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.
