ImmunityBio Announces Insurance Coverage of ANKTIVA® Across Multiple States with First Commercial Doses Administered Just Weeks After FDA Approval—Opening New Era for Immunotherapy Beyond Checkpoint Inhibitors

Jun 20, 2024

  • Multiple patients treated across the U.S. with ANKTIVA less than eight weeks after FDA approval of first-in-class cytokine immunotherapy for BCG unresponsive non-muscle invasive bladder cancer
  • ANKTIVA launch initiates the next era of immunotherapy beyond checkpoint inhibitors that is based on cytokines and natural killer (NK) cells
  • ANKTIVA’s novel mechanism of action activates the body’s immune system of natural killer and killer T cells to attack BCG resistant tumor cells and induce memory T cells resulting in a long duration of complete response exceeding 47 months1
  • ANKTIVA reimbursement now covered by multiple healthcare plans
  • Urologists treating eligible bladder cancer patients can learn more about the treatment option and access support program ImmunityBio CARE™ at

CULVER CITY, Calif., June 20, 2024 — ImmunityBio, Inc. (NASDAQ: IBRX) today announced the initial treatment of multiple patients in the United States to receive therapy with ANKTIVA® (nogapendekin alfa inbakicept-pmln), ImmunityBio’s recently approved immunotherapy for Bacillus Calmette-Guérin (BCG)-unresponsive non-muscle invasive bladder cancer (NMIBC) carcinoma in situ. ANKTIVA was approved by the U.S. Food and Drug Administration (FDA) on April 22, 2024 for the treatment of patients with BCG-unresponsive NMIBC CIS with or without papillary tumors.

The intravesical therapy employs a combination of ANKTIVA, an IL-15 agonist in combination with BCG. The combination is the first FDA-approved immunotherapy in NMIBC that functions by activating the body’s NK and killer T-cell immune system to attack tumor cells, while simultaneously activating memory T cells, leading to a prolonged duration of complete response exceeding 47 months for some patients.

“We are grateful to be able to offer this first-in-class immunotherapy to qualified bladder cancer patients less than two months after the therapeutic was approved by the FDA,” said Patrick Soon-Shiong, M.D., Executive Chairman and Global Chief Scientific and Medical Officer at ImmunityBio. “The interest in this next era of immunotherapy beyond checkpoint inhibitors—the era of cytokines—from urologists treating NMIBC patients has been strong and we look forward to offering more patients an alternative to bladder removal.”

The first patients to receive commercial doses are located throughout the U.S. and several are being treated by community urologists, as the therapy does not require any special handling or equipment that would limit its use to specialty medical centers.

“In addition to its unique mechanism of action, ANKTIVA can be readily administered by urologists in their own offices and clinics enabling more patients to receive it in familiar settings from their own providers,” said Richard Adcock, President and CEO of ImmunityBio. “We look forward to ANKTIVA reaching more and more eligible NMIBC patients and for our science to deliver even more therapies from our pipeline.”

ANKTIVA received Breakthrough Therapy Designation and approval from the FDA based on the safety and efficacy outcome of complete responses (CR) and duration of complete response (DOR) in BCG-unresponsive NMIBC CIS. The 77 evaluable patients in this single-arm, multicenter trial received ANKTIVA with BCG maintenance therapy for up to 37 months. The tumor status was assessed with cystoscopy and urine cytology and will continue for up to five years after each patient began their participation in the trial.

The CR rate for the 77 evaluable patients was 62% with the upper end of the confidence interval being 73%. The duration of complete response as of the November 2023 cut-off was more than 47 months and is ongoing to date. These prolonged duration of complete response results beyond 24 months with ANKTIVA and BCG exceed the benchmark for the magnitude of meaningful clinical results suggested by a panel of experts at the International Bladder Cancer Group.

In May, ImmunityBio announced it had drug substance sufficient for 170,000 doses of ANKTIVA for commercial and clinical trial use.

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.

Selected Safety Information for ANKTIVA

The most common (≥15%) adverse reactions, including laboratory test abnormalities, are increased creatinine, dysuria, hematuria, urinary frequency, micturition urgency, urinary tract infection, increased potassium, musculoskeletal pain, chills, and pyrexia.

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 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.

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.
