CULVER CITY, Calif.--(BUSINESS WIRE)--ImmunityBio, Inc. (NASDAQ: IBRX), a leading immunotherapy company, today announced that the Company received a Refusal to File (RTF) letter from the U.S. Food and Drug Administration (FDA) for the supplemental biologics license application (sBLA) for use of ANKTIVA plus Bacillus Calmette-Guerin (BCG) in BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) for the indication of papillary disease. This RTF letter was received despite reaching unanimous guidance and encouragement at the in-person January 2025 meeting from the leadership of the Agency, including from CBER, CDER and OCE to submit this sBLA. At this meeting all key decision makers were specifically asked and unanimously confirmed that ImmunityBio should submit the sBLA as soon as possible based on the data in the single-arm trial. Relying on this unanimous guidance the Company submitted the sBLA in March 2025. The Company has already requested an urgent meeting to resolve the inconsistencies between the directives provided at the January Meeting and receipt of the RTF letter. ANKTIVA was approved by the FDA in 2024 with BCG for the treatment of BCG unresponsive NMIBC with Papillary tumors with CIS (Cohort A). In the same clinical trial (QUILT-3.032) long term results of patients with Papillary tumors without CIS (Cohort B), was submitted as a sBLA. The RTF letter referenced herein does not impact this prior approval of CIS +/- Papillary in BCG unresponsive patients. The Agency leaders present at the January meeting unambiguously invited the Company to expeditiously submit an sBLA for the NMIBC papillary indication based on the strength of the clinical response and long-term duration of follow-up data of the Papillary without CIS cohort of the QUILT 3.032 study. Data was also presented of the long term follow-up Phase 1 results which demonstrated Complete Response and Disease Free Survival in both CIS and Papillary disease, with patients in on-going cystectomy free state at 10 years. In addition disease-specific overall survival rate of 99% at 12 months and 96% at 36 months, in the BCG unresponsive patients with Papillary disease without CIS was discussed. To our knowledge, this is the most durable data to date in the Papillary setting for bladder preservation. In March 2025, the Company completed its submission to the FDA of the sBLA for the use of ANKTIVA plus BCG in BCG-unresponsive NMIBC in the papillary indication. On May 2, 2025, and notwithstanding the FDA’s invitation to submit the sBLA articulated by its leadership at the January Meeting, the FDA delivered an RTF letter. The Company together with its consultants who attended the January 2025 meeting were shocked by this inconsistent response and have requested an urgent meeting with the Agency to resolve this issue. “Our commitment to NMIBC patients in the papillary indication and our belief in ANKTIVA’s potential based on the strength of the clinical response and long duration of 5-year follow-up remains unchanged, despite our receipt of a refusal to file letter regarding our supplemental BLA,” said Dr. Patrick Soon-Shiong, the Company’s Founder, Executive Chairman and Global Chief Scientific and Medical Officer. “We are fully determined to work with the FDA as quickly as possible, including having already requested a Type A meeting, to explore the best path forward. We would also welcome an FDA Advisory Committee meeting as part of the regulatory process going forward. We presented our data at the recent 2025 American Urological Association (AUA) meeting and ANKTIVA+BCG was considered best in class and best in disease by the thought leaders in attendance, when compared to all the therapies currently approved or in development. Patients with BCG Unresponsive Papillary disease, face a life changing and life-threatening prospect of a total radical cystectomy, as well as the danger of the disease progressing from non-muscle invasive to muscle invasion with consequent progression and mortality. With the data presented of 99% disease specific survival at 12 months and over 82% patients not requiring bladder removal, it is essential that these patients be provided this treatment option, especially with the safety profile of ANKTIVA+BCG and the already approved indication of Papillary disease with CIS. The Company presented these data to the Agency in person in January and the Agency leaders present unanimously encouraged the company to expeditiously submit a supplemental BLA for this indication.” Dr. Soon-Shiong further stated: “The Agency must explain the confounding inconsistency of approving ANKTIVA+BCG for patients with Papillary with CIS disease, while refusing to file the sBLA for patients with Papillary without CIS disease—even though both groups were part of the same trial, in the same high-risk population of BCG-unresponsive non-muscle invasive bladder cancer. In both cases, patients received the same surgical procedure for the Papillary component, the same therapy at the same dose, with the same excellent tolerability and meaningful clinical benefit: over 82% bladder-sparing and over 96% disease-specific survival at 36 months, as shown in Figure 1. On behalf of patients facing a potential loss of a vital organ and high risk of progression of disease, I urge the Agency to reconsider and act now.” “I actively participated in the January 2025 meeting at which the leadership of the Agency present at that meeting unanimously supported and encouraged ImmunityBio to submit results from the single arm trial, QUILT 3.032 as a supplemental BLA because of the high-risk of progression and metastasis these patients with BCG unresponsiveness face. The consensus was reached by all present, including me, because of the lack of satisfactory alternatives in this desperately ill population at high-risk of losing their bladder – a life threatening and life changing procedure. Thus, I was startled to learn the ImmunityBio had received a ‘Refuse to File’ letter which is in my opinion rife with regulatory inaccuracies. I recommend that the company seek a rapid meeting with the Agency to resolve this issue and minimize the delay and threat to well-being of patients who could benefit significantly from avoiding a cystectomy,” said Dr. Rachel Sherman, former FDA Principal Deputy Commissioner, who pioneered single arm trials at the height of the HIV epidemic, and was responsible for developing the expedited pathways at the Agency to address life threatening and serious diseases on behalf of the American public during her 30 year career at the agency. “Furthermore, it is incomprehensible to me that the FDA refuses to file a supplemental BLA, stating the study is not sufficient to support a regulatory review, when it has already approved a product based on that very same study in essentially the same indication and population. As stated above, these patients are suffering from a disease with a high risk of morbidity and mortality in the very short term – no delay should be tolerated,” added Dr. Sherman. About the QUILT-3.032 Study QUILT-3.032 (NCT03022825) is a Phase II/III, open-label, single-arm, multicenter study of intravesical BCG plus ANKTIVA or ANKTIVA only in patients with BCG unresponsive high grade non-muscle invasive bladder cancer (NMIBC). All participants receive BCG plus ANKTIVA (Cohorts A and B) or ANKTIVA only (Cohort C) via a urinary catheter in the bladder for 6 consecutive weeks (initial induction treatment period). After the first disease assessment, eligible patients receive either a 3-week maintenance course or a 6-week re-induction course (second treatment period) at Month 3. Eligible patients will continue to receive maintenance treatment in the third treatment period at Months 6, 9, 12, and 18. Eligible patients have the option to receive maintenance treatment in the fourth treatment period at Months 24, 30, and 36. The study duration is 60 months. Cohort A (N=100) includes patients with histologically confirmed BCG-unresponsive NMIBC CIS with or without papillary disease. The primary endpoint is biopsy-confirmed complete response (CR) rate at any time. Secondary endpoints include duration of CR, progression-free survival (PFS), time to cystectomy, safety and overall survival. FDA Approved this indication in 2024 in which eligibility included patients with Papillary disease. Cohort B (N=80) enrolled participants with histologically confirmed BCG-unresponsive high-grade Papillary disease without CIS. The primary endpoint is a response of a disease-free rate at 12 months. Secondary endpoints include disease-free survival DFS and disease-specific survival, PFS, time to cystectomy, safety and overall survival. About ANKTIVA® 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 receptor 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. ANKTIVA was approved by the FDA in 2024 with BCG for the treatment of adult patients with BCG-unresponsive non-muscle invasive bladder cancer with CIS with or without papillary tumors.

Oral presentation from QUILT-3.032 study showed 71% complete response rate (N=100), with duration of response ranging up to more than 53 months, in BCG-unresponsive NMIBC CIS with or without papillary disease Probability of duration of complete response of at least 45 months in the FDA label population (N=77) is 51%, with median duration of complete response of 45.4 months Cystectomy avoidance rate in responders of 84% at 36 months Disease-specific overall survival rate of 99% at 36 months Longest follow-up of BCG-unresponsive CIS patients with unmatched more than 5 years data available (as of July 2024 data cutoff) Disease-free survival rate of 58% at 12 months (primary endpoint) and 52% at 24 months Cystectomy avoidance rate of 82% at 36 months—unmatched by any product in the field to date Disease-specific overall survival rate of 96% at 36 months Supplemental BLA submitted for FDA approval for this indication CULVER CITY, Calif.--(BUSINESS WIRE)--ImmunityBio, Inc. (NASDAQ: IBRX), a leading immunotherapy company, today announced positive long-term results from its QUILT-3.032 study of ANKTIVA® (nogapendekin alfa inbakicept-pmln) plus Bacillus Calmette-Guérin (BCG) for the treatment of adult patients with BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) carcinoma in situ (CIS), with or without papillary disease. The findings were shared during an oral presentation at the American Urological Association Annual Meeting (AUA 2025) in Las Vegas, April 26-29. At the 2025 AUA Annual Meeting, ImmunityBio presented updated clinical data highlighting the durability and impact of ANKTIVA in combination with BCG. The results demonstrated the longest duration of complete response and highest rate of cystectomy avoidance among therapies studied in BCG-unresponsive NMIBC, including both CIS with or without papillary disease and papillary-only disease without CIS. The latest results from Cohort A (N=100) of the QUILT-3.032 study showed treatment with ANKTIVA plus BCG resulted in a complete response rate of 71% in patients with BCG-unresponsive NMIBC CIS with or without papillary tumors. Responses ranged up to more than 53 months, with 60% of responses having a duration of at least 12 months. Exceptional ongoing complete response data were presented for the FDA label population (N=77), which has a longer follow-up time of 29.3 months and showed a 51% probability of duration of complete response of at least 45 months. The rate of cystectomy avoidance in responders was 84.2% at 36 months, with disease-specific overall survival of 99% at 36 months. In study Cohort B (N=80) of patients with BCG-unresponsive NMIBC papillary disease without CIS, ANKTIVA plus BCG demonstrated a 58.2% disease-free survival (DFS) rate at 12 months (primary endpoint), with a median DFS of 25.3 months. The cystectomy avoidance rate was 82% at 36 months, with a disease-specific overall survival rate of 96% at 36 months. “While BCG is the commonly used first-line therapy for newly diagnosed high-risk non-muscle invasive bladder cancer, many patients will be refractory or relapse after an initial response and be diagnosed as BCG-unresponsive,” said QUILT-3.032 principal investigator and study presenter Sam S. Chang, M.D., Professor of Urology and Chief Surgical Officer of the Vanderbilt Ingram Cancer Center. “Our latest findings, including an 82% cystectomy avoidance rate, provide additional evidence that ANKTIVA has the ability to restore BCG activity and promote durable complete responses and, most importantly, help patients preserve their bladder for a prolonged duration from surgery in both CIS, as well as papillary without CIS disease.” The latest findings from the QUILT-3.032 study also show that therapy with ANKTIVA plus BCG was well tolerated in both CIS and papillary NMIBC (N=180). Most treatment-related adverse events (TRAEs) were grade 1 or 2 and related to intravesical instillation consistent with BCG alone - dysuria, pollakiuria, hematuria and micturition urgency. TRAEs of grade 3 occurred at a rate of 3% (6 subjects out of 180). No grade 4 or 5 TRAEs were observed. “We are pleased with these unmatched long-term follow up results which further illustrate ANKTIVA’s potential to improve outcomes and quality of life for patients with non-muscle invasive bladder cancer in both indications of CIS, as well as papillary disease without CIS,” said Dr. Patrick Soon-Shiong, Executive Chairman and Global Chief Medical and Scientific Officer of ImmunityBio. “The cystectomy avoidance rate of greater than 82% at 36 months in both BCG-unresponsive CIS with or without papillary disease and in BCG-unresponsive papillary without CIS disease is the highest percentage of bladder sparing and longest duration of complete response and disease-free status seen in this patient population to date, as confirmed by all the studies presented in the field at the AUA 2025 conference. We look forward to the national guidelines (NCCN) for BCG-unresponsive papillary disease without CIS to align with these long-term data of cystectomy avoidance and the data presented at AUA supporting Anktiva as the best in class and best in disease for this indication.” Based on findings from the QUILT-3.032 study, ImmunityBio recently submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for use of ANKTIVA plus BCG in BCG-unresponsive NMIBC for the indication of papillary disease. 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.1 About the QUILT-3.032 Study QUILT-3.032 (NCT03022825) is a Phase II/III, open-label, single-arm, multicenter study of intravesical BCG plus ANKTIVA or ANKTIVA only in patients with BCG unresponsive high grade non-muscle invasive bladder cancer (NMIBC). All participants receive BCG plus ANKTIVA (Cohorts A and B) or ANKTIVA only (Cohort C) via a urinary catheter in the bladder for 6 consecutive weeks (initial induction treatment period). After the first disease assessment, eligible patients receive either a 3-week maintenance course or a 6-week re-induction course (second treatment period) at Month 3. Eligible patients will continue to receive maintenance treatment in the third treatment period at Months 6, 9, 12, and 18. Eligible patients have the option to receive maintenance treatment in the fourth treatment period at Months 24, 30, and 36. The study duration is 60 months. Cohort A (N=100) includes patients with histologically-confirmed BCG-unresponsive NMIBC CIS with or without Ta/T1 papillary disease. The primary endpoint is biopsy-confirmed complete response (CR) rate at any time. Secondary endpoints include duration of CR, progression-free survival (PFS), time to cystectomy, safety and overall survival. Cohort B (N=80) enrolled participants with histologically-confirmed BCG-unresponsive high-grade Ta/T1 papillary NMIBC. The primary endpoint is disease-free rate at 12 months. Secondary endpoints include disease-free survival, PFS, time to cystectomy, safety and overall survival.
