ImmunityBio Expands Access to ANKTIVA® in EU with New Distribution Partnership and Opens Irish Subsidiary to Support European Launch

Key Terms

non-muscle invasive bladder cancer medical

A form of bladder cancer that is confined to the inner lining of the bladder and has not grown into the deeper muscle layer; think of it like a stain on wallpaper rather than damage to the wall’s studs. It matters to investors because it has different treatment, monitoring and recurrence patterns than deeper cancers, driving demand for repeated outpatient procedures, local therapies and diagnostic tests that affect revenue, trial design and pricing dynamics in healthcare markets.

carcinoma in situ medical

Carcinoma in situ is an early-stage abnormal growth where cells look cancerous but remain confined to the tissue surface and have not invaded deeper layers or spread to other parts of the body; think of it like graffiti on a wall that hasn’t cracked the plaster beneath. For investors, it matters because treatments, regulatory pathways, clinical trial outcomes and long-term costs differ greatly between contained lesions and invasive cancer, influencing market value, approval odds and liability for healthcare companies.

Bacillus Calmette-Guérin (BCG) medical

Bacillus Calmette-Guérin (BCG) is a live, weakened strain of bacteria used as a vaccine against tuberculosis and as a longstanding immune-stimulating therapy for certain cancers, most commonly bladder cancer. Investors watch BCG because its supply, regulatory approvals, production capacity and clinical trial results can affect sales, treatment availability and healthcare costs—think of it like a widely used, older tool whose availability and regulatory standing can sway demand and company revenues.

conditional marketing authorization regulatory

A conditional marketing authorization is a limited, temporary approval from a drug regulator that lets a medicine or vaccine be sold based on earlier or smaller amounts of safety and effectiveness data than normally required, usually because the treatment addresses a serious unmet need. It matters to investors because it can allow a company to start generating revenue sooner—like a provisional driver’s license—while carrying higher regulatory and clinical risk if follow‑up studies fail or additional data are required.

complete response rate medical

Complete response rate is the percentage of patients in a clinical trial whose measurable signs of disease disappear after treatment, as judged by predefined medical tests. For investors, a higher complete response rate is a strong signal that a drug works well in the trial setting, improving chances of regulatory approval and commercial success — like seeing most lightbulbs in a new batch actually turn on before deciding to buy the factory.

randomized trial medical

A randomized trial is a study where participants are assigned by chance—like flipping a coin—to different treatments or to a comparison group so the results reflect the effect of the treatment rather than other factors. Investors care because these trials provide the most reliable evidence about whether a drug, device, or strategy works, and strong, clear results can change a company’s approval prospects, market size and risk profile quickly.

accelerated approval regulatory

Accelerated approval is a process that allows new medical treatments to be approved more quickly than usual if they address serious or life-threatening conditions and show promising early results. For investors, it signals that a treatment may reach the market sooner, potentially boosting a company's prospects, but it also involves some uncertainty since full evidence of effectiveness is still being gathered.

immunotherapy medical

Treatment that uses or enhances the body’s immune system to detect and fight disease, most often cancers or chronic infections; think of it as training or arming the body’s own soldiers to find and destroy targets. It matters to investors because successful immunotherapies can lead to high-value drug approvals, recurring revenue from long-term treatments, and changes in competitive dynamics, while failures or safety issues in clinical trials can materially affect company valuations.

CULVER CITY, Calif.--(BUSINESS WIRE)-- ImmunityBio, Inc. (NASDAQ: IBRX), a commercial-stage immunotherapy company, today announced a partnership with Accord Healthcare to provide access to ANKTIVA^® (nogapendekin alfa inbakicept) in combination with Bacillus Calmette-Guérin (BCG) for eligible patients in the European Union with BCG-unresponsive non-muscle invasive bladder cancer carcinoma in situ (NMIBC CIS), with or without papillary disease. ImmunityBio also announced the establishment of an Irish subsidiary in Dublin to support the company’s distribution and commercialization strategy throughout Europe.

“Our partnership with Accord marks a significant step in our European growth strategy and our mission to redefine cancer care,” said Richard Adcock, President and CEO of ImmunityBio. “Accord’s scale, oncology leadership, and commercial reach support our goals to broaden patient access to ANKTIVA and unlock its full commercial potential in Europe.”

As part of the partnership, Accord Healthcare will utilize over 100 Sales, Medical, and Marketing professionals to drive commercialization of ANKTIVA in the UK, European Union, as well as European Free Trade Association members Iceland, Liechtenstein, and Norway.

“Our partnership with ImmunityBio reflects our shared commitment to expanding access to innovative cancer therapies for patients in Europe,” said Paul Tredwell, Global CEO at Accord Healthcare. “ANKTIVA represents an important advancement for eligible patients with BCG-unresponsive NMIBC CIS, and we are pleased to support its introduction across our markets.”

“With approvals now spanning 33 countries, ImmunityBio has expanded global access to ANKTIVA for those with BCG-unresponsive NMIBC CIS, with or without papillary disease,” said Dr. Patrick Soon-Shiong, Founder, Executive Chairman, and Global Chief Scientific and Medical Officer of ImmunityBio. “The 71% complete response rate and the durability of those responses support ANKTIVA’s role as a foundational backbone of next-generation immunotherapy for bladder cancer. Our goal is to further broaden access by rapidly completing the randomized trial in patients with BCG-naïve disease. In parallel, we have submitted our response to the U.S. FDA’s request for additional data related to BCG-unresponsive papillary-only NMIBC, and we await the Agency’s review.”

ANKTIVA in combination with BCG for the treatment of BCG-unresponsive NMIBC CIS is now authorized across four major regulatory jurisdictions, encompassing 33 countries. These approvals include the United States (FDA, April 2024), the United Kingdom (MHRA, July 2025), the Kingdom of Saudi Arabia (SFDA accelerated approval, January 2026), and the European Union, where the European Commission granted conditional marketing authorization in February 2026 covering 27 EU member states plus Iceland, Liechtenstein, and Norway.

About ANKTIVA^® (nogapendekin alfa inbakicept)

ANKTIVA is a first-in-class interleukin-15 (IL-15) receptor agonist (ATC code: L03AC03) consisting of an IL-15 mutant (IL-15N72D) bound to an IL-15 receptor alpha Fc fusion protein. In the European Union, ANKTIVA is available as a 400 µg concentrate for intravesical suspension. ANKTIVA binds with high affinity to IL-15 receptors on natural killer (NK) cells, CD4+ T cells, and CD8+ T cells, activating and expanding these immune effector populations. By activating NK cells, ANKTIVA addresses tumor immune escape mechanisms, while simultaneously restoring memory T cell activity to generate durable antitumor responses. ANKTIVA has improved pharmacokinetic properties, longer persistence in lymphoid tissues, and enhanced antitumor activity compared to native IL-15 in vivo.

IMPORTANT SAFETY INFORMATION

INDICATION AND USAGE: ANKTIVA in combination with Bacillus Calmette-Guérin (BCG) is indicated for the treatment of adult patients with BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) with or without papillary tumours.

WARNINGS AND PRECAUTIONS: The possibility of severe systemic BCG-infections with the necessity of anti-tuberculosis therapy should be considered before initiating the BCG-therapy.

Delaying cystectomy in patients with BCG-unresponsive NMIBC with CIS, with or without papillary tumours, treated with ANKTIVA therapy in combination with BCG could lead to development of muscle invasive or metastatic bladder cancer.

If patients with CIS that are medically eligible for cystectomy have not achieved a CR (absence of disease or low-grade Ta) to treatment after an induction course of ANKTIVA in combination with BCG at the 12-weeks assessment, cystectomy should be reconsidered as an alternative to re-induction. The risk of developing muscle-invasive or metastatic bladder cancer increases the longer cystectomy is delayed in the presence of persisting CIS.

DOSAGE AND ADMINISTRATION: For intravesical use only. ANKTIVA should NOT be administered by subcutaneous or intravenous or intramuscular use.

From a microbiological point of view, unless the method of opening/reconstitution/dilution precludes the risk of microbial contamination, the product should be used immediately. If not used immediately, in-use storage times and conditions are the responsibility of the user.

ANKTIVA is administered intravesically as a mixture with BCG.

USE IN SPECIFIC POPULATIONS: Pregnancy: Treatment is not recommended during pregnancy and in women of childbearing potential not using effective contraception.
