ASCO25: PanGIA Biotech's AI-based urine test for prostate cancer hits trial success
With early detection of prostate cancer recognised as a critical part in reducing the disease's mortality rate, PanGIA Biotech has shared results from a study validating its artificial intelligence (AI)-based liquid biopsy in vitro diagnostic (IVD) for detecting early prostate cancer from urine samples. The US company's detection methodology involves analysing urinary biosignatures using AI and machine learning models, which the company asserts may prove beneficial over invasive biopsies or blood-based tests that may miss early-stage cases while also eliminating the need for sequencing. PanGIA's prospective study involved 197 biopsy-confirmed prostate cancer patients and 84 healthy controls, with the test demonstrating strong performance in detecting intermediate- and low-grade cancers, and high recall (>0.89) across Gleason scores 6 through 10. The AI/ML classification model was also found to be effective as measured by F1 score. The study's findings were presented at the American Society of Clinical Oncology (ASCO) 2025 meeting, taking place in Chicago, Illinois between 30 May and 3 June. 'This study confirms what we've believed from the start: there's power in non-invasive, data-driven diagnostics,' PanGIA CEO Holly Magliochetti. 'Our platform helps clinicians detect prostate cancer when intervention is most effective – without costly or invasive procedures.' Past research indicates that with early detection, the five-year survival rate for prostate cancer is over 99%. According to GlobalData's Pipeline Products database, there are 142 prostate cancer IVDs at active stages of development globally. Growing at a CAGR of 3.5%, the overall global IVD market is forecast to reach a valuation of around $45.9m by 2024, up from $32.4m in 2024, as per GlobalData analysis. In other prostate cancer news from ASCO 2025, researchers from the UK's Institute of Cancer Research (ICR) and University College London (UCL) demonstrated that an AI-based test developed by US-based Artera can help identify which men with non-metastatic high-risk prostate cancer are most likely to benefit from being administered abiraterone. A recent large report by Philips on the passage of AI adoption and innovation in healthcare reflected that while clinicians are chiefly on board with the AI and recognise its value in healthcare settings, 46% of respondents stated that slow adoption of AI was contributing towards missed opportunities for early diagnosis and intervention.

ASCO Report of Pioneering Treatment of Lymphopenia with Significant Overall Survival Benefit in Advanced Pancreatic Cancer
CULVER CITY, Calif.--(BUSINESS WIRE)--ImmunityBio, Inc. (NASDAQ: IBRX) today announced results presented at ASCO 2025 of the first known treatment for lymphopenia with ANKTIVA and CAR-NK therapy. This data supports that reversal of lymphopenia, a well-established root cause of early mortality in patients with cancer across all tumor types, correlates with significant improved survival. While anemia and neutropenia have long been addressed by agents like Epogen and Neupogen, no therapy has ever existed for lymphopenia—until now. ANKTIVA (nogapendekin alfa inbakicept-pmln), an IL-15 superagonist approved in April 2024 for BCG-unresponsive non-muscle- invasive bladder cancer carcinoma in situ with or without papillary disease, represents the first lymphocyte-stimulating agent (LSA) capable of expanding lymphocytes critical for immunogenic cell death, such as natural killer (NK) and T cells. These findings emphasize the need for a therapy to overcome treatment induced lymphopenia with higher mortality as presented at ASCO 2025 by several institutions (Abstract # 8054, Satoskar et al. and Abstract # 2663, Saleh et al.) In a single-arm QUILT-88 clinical trial of 86 participants with third-to-sixth-line metastatic pancreatic cancer with very high tumor burden (CA19-9 levels exceeding 34,000 IU/ml), for which no therapy currently exists, patients received ANKTIVA subcutaneously in combination with off-the-shelf, ex-vivo infusion of CAR-NK cells (PD-L1 t-haNK) and low dose immuno-modulating chemotherapy. This first reported study of treating lymphopenia demonstrated significant differences in median overall survival in subjects whose lymphopenia was reversed (Absolute Lymphocyte Count: ALC ≥ 1,000). In 67 out of 86 subjects, reversal of lymphopenia was achieved and median overall survival was significantly prolonged compared to those who remained in severe lymphopenia with P-value 0.005, HR: 0.46 (0.26, 0.80) in Figure 1. In subjects with lymphopenia rescue and a lower tumor burden (less than the median CA19-9 of 34,000 IU/mL), the median overall survival in these very advanced metastatic pancreatic cancer patients exceeded 10 months (Figure 2). These findings of improved survival in pancreatic cancer patients with lower tumor burden point to the potential of further prolonged overall survival in pancreatic cancer patients if treated in the first line or neoadjuvant stages of disease. Highlighting the importance of lymphopenia reversal, Oncologist published a peer-reviewed paper titled ' Recurrent pancreatic cancer treated with N-803 and PD-L1 t-haNK followed by an EGFR-targeted nanocell drug conjugate,' demonstrating that in a patient with 2nd line metastatic pancreatic cancer treated with the full Cancer BioShield platform—including ANKTIVA, CAR-NK cells (PD-L1 t-haNK), and antigen-targeting adenoviruses—remained in remission for over six years and maintains a high quality of life at the date of this release. The expanded access authorization announced yesterday enables patients across all solid tumor types who have exhausted first-line therapy including chemotherapy, radiation, or immunotherapy to receive Anktiva as a lymphocyte stimulating agent to protect the immune system from the lymphogenic adverse effects of current standards of care. The ASCO Annual Meeting 2025 materials from ImmunityBio can be found below: Association of lymphopenia rescue and CA19-9 levels with overall survival following IL-15 superagonist N-803 and PD-L1 t-haNK chemo-immunotherapy for 3rd line or greater metastatic pancreatic cancer. Abstract Text: Poster PDF: About the Cancer BioShield™ Platform The Cancer BioShield platform is a first-in-class immunotherapy strategy designed to restore immune competence by reversing lymphopenia—the loss of functional immune cells caused by cancer itself and by conventional treatments such as chemotherapy, radiation and immunotherapy. At its core is ANKTIVA® (nogapendekin alfa inbakicept-pmln), an IL-15 agonist approved for BCG-unresponsive non-muscle-invasive bladder cancer CIS with or without papillary disease, activates and proliferates natural killer (NK) cells and CD4+ and CD8+ T cells, restoring lymphocyte levels critical for immunosurveillance, immunogenic cell death, and long-term tumor control. The platform employs a multi-modal approach: In-vivo stimulation: Subcutaneous administration of ANKTIVA expands NK and T cells, boosting anti-tumor immunity. Ex-vivo targeted cytotoxicity: Off-the-shelf PD-L1 t-haNK CAR-NK cells are engineered to target and eliminate PD-L1–expressing tumor cells and immunosuppressive neutrophils (myeloid-derived suppressor cells), enhancing anti-tumor specificity and reducing immune evasion. Memory Cytokine-Enriched Natural Killer (M-ceNK) cell therapy: M-ceNK cells are developed via cytokine activation and expansion of autologous and allogeneic NK cells collected through apheresis, potentially providing long-term immune memory and sustained cytotoxic capacity. Together, these components offer a comprehensive, novel, immune-restoring therapeutic platform aimed at not only expanding effector immune cells but also overcoming tumor-mediated immune suppression to support long-term disease control. The platform's effectiveness can be tracked through universally utilized, simple complete blood count (CBC): increases in absolute lymphocyte count (ALC) reflect ANKTIVA's lymphocyte-stimulating activity, while reductions in the neutrophil-to-lymphocyte ratio (NLR) demonstrate PD-L1 t-haNK's immunosuppressive neutrophil targeting. Low ALC and high NLR levels are laboratory measurements that have been extensively reported as predictive biomarkers of poor prognosis with early mortality across all tumor types 5,6. The data presented by ImmunityBio for the first time demonstrates that improving ALC and NLR correlates with significant enhanced overall survival and clinical benefit. About Lymphopenia and Absolute Lymphocyte Count (ALC) Lymphopenia—the loss of key immune cells such as NK, CD4+, and CD8+ T cells—is a common side effect of chemotherapy 1, radiation 2,3, and some immunotherapies 4. Unlike anemia and neutropenia, which have FDA-approved treatments like EPO and Neupogen, no therapy previously existed to treat this immune cell depletion. Lymphopenia weakens the immune system, increases infection risk, and is linked to early death across many cancer types 5. Low Absolute Lymphocyte Count (ALC) is a recognized poor prognostic marker. ANKTIVA ® is the first approved therapy to restore lymphocyte levels by activating and expanding NK and T cells—without increasing immunosuppressive T regulatory cells 7.

IMUNON Announces Data Presented at ASCO Reinforces Unprecedented Overall Survival in Ovarian Cancer Phase 2 Study
Consistent OS Efficacy Benefit Across Multiple Treatment Subgroups Demonstrates IMNN-001's Ability to Recruit a Powerful Anti-Cancer Immune Response Results, presented simultaneously in oral presentation at ASCO 2025 and in peer-reviewed Gynecologic Oncology, suggest very meaningful survival effect of IMNN-001 in women HRP and HRD positive, including those with BRAC1 and BRCA2 mutations LAWRENCEVILLE, N.J., June 03, 2025 (GLOBE NEWSWIRE) -- IMUNON , Inc. (NASDAQ: IMNN), a clinical-stage company in Phase 3 development of its DNA-mediated immunotherapy, today announced positive data from the Company's Phase 2 OVATION 2 Study showing that treatment with IMNN-001 in women with newly diagnosed advanced ovarian cancer resulted in consistent, clinically meaningful improvements in several key endpoints across treatment groups, including overall survival (OS), progression-free survival (PFS), chemotherapy response score and surgical response. Treatment with IMNN-001 also showed a favorable safety profile, with no reports of serious immune-related adverse events. The full results are being presented today in an oral presentation at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, Illinois, and simultaneously published in the peer-reviewed journal Gynecologic Oncology . Participants with newly diagnosed advanced epithelial ovarian cancer in the Phase 2 OVATION 2 Study (n=112) were randomized 1:1 to evaluate the safety and efficacy of IMNN-001 (100 mg/m2 administered intraperitoneally weekly) plus neoadjuvant and adjuvant chemotherapy (N/ACT) compared to standard of care (SoC) N/ACT alone, with a median follow-up of 31 months. The data being presented today highlight the consistent results achieved across all treatment groups, demonstrating: Median 13-month increase in OS (46 vs. 33 months) and median 3-month increase in PFS (14.9 vs. 11.9 months) in IMNN-001 treatment arm compared to standard of care alone. Better therapeutic effect observed with IMNN-001 treatment compared to the control arm (p=0.0375), as shown by mean 6.5-month extension of time free of progression or death (PFS + OS) captured in totality of treatment effect. Use of poly ADP-ribose polymerase (PARP) inhibitors as part of maintenance therapy further enhanced outcomes, with median OS not yet reached in IMNN-001 treatment arm after >5 years compared to 37 months on standard of care. Chemotherapy response score highlights double the response rate of a complete or near complete histopathological response following treatment with 26.1% in the IMNN-001 treatment arm compared to 13.0% in the control arm. Surgical response rate of no macroscopic residual tumor left after surgery 64.6% in the IMNN-001 treatment arm compared to 52.1% in the control arm. Hazard ratio of 0.78 in study participants who are homologous recombination proficient (HRP) and hazard ratio of 0.42 in women positive for homologous recombination deficiency (HRD+), including BRCA1 or BRCA2 mutations, suggesting increased therapeutic activity. IMNN-001 was generally safe and well tolerated, with no reports of cytokine release syndrome, systemic toxicity or serious immune-related adverse events (AEs). The most common AEs primarily included abdominal pain, nausea and vomiting. 'These data highlighting the consistency of results across all treatment groups are a true testament to the power of our TheraPlas technology and the potential of IMNN-001 to transform the treatment paradigm of women who are newly diagnosed with advanced ovarian cancer and in desperate need of new treatment options,' said Stacy Lindborg, Ph.D., president and chief executive officer of IMUNON. 'Results were consistent across a variety of participants, including women who receive PARP inhibitors, who are HRP and HRD positive, and who have BRCA1 and BRCA2 mutations. We are grateful for the continued support and participation of study participants and investigators and look forward to advancing our pivotal Phase 3 OVATION 3 trial of IMNN-001, with the first two trial sites recently initiated.' The OVATION 2 Study oral presentation and journal manuscript will both be available on the 'Scientific Presentations' page of IMUNON's website at . About the Phase 2 OVATION 2 Study OVATION 2 evaluated the dosing, safety, efficacy and biological activity of intraperitoneal administration of IMNN-001 in combination with neoadjuvant and adjuvant chemotherapy (N/ACT) of paclitaxel and carboplatin in patients newly diagnosed with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer. Treatment in the neoadjuvant period is designed to shrink the tumors as much as possible for optimal surgical removal after three cycles of chemotherapy. Following N/ACT, patients undergo interval debulking surgery, followed by three additional cycles of adjuvant chemotherapy to treat any residual tumor. This open-label study enrolled 112 patients who were randomized 1:1 and evaluated for safety and efficacy to compare N/ACT plus IMNN-001 versus standard-of-care N/ACT. In accordance with the study protocol, patients randomized to the IMNN-001 treatment arm could receive up to 17 weekly doses of 100 mg/m2 in addition to N/ACT. As a Phase 2 study, OVATION 2 was not powered for statistical significance. Additional endpoints included objective response rate, chemotherapy response score and surgical response. About IMNN-001 Immunotherapy Designed using IMUNON's proprietary TheraPlas® platform technology, IMNN-001 is an IL-12 DNA plasmid vector encased in a nanoparticle delivery system that enables cell transfection followed by persistent, local secretion of the IL-12 protein. IL-12 is one of the most active cytokines for the induction of potent anticancer immunity acting through the induction of T-lymphocyte and natural killer cell proliferation. IMUNON previously reported positive safety and encouraging Phase 1 results with IMNN-001 administered as monotherapy or as combination therapy in patients with advanced peritoneally metastasized primary or recurrent ovarian cancer and completed a Phase 1b dose-escalation trial (the OVATION 1 Study) of IMNN-001 in combination with carboplatin and paclitaxel in patients with newly diagnosed ovarian cancer. IMUNON previously reported positive results from the recently completed Phase 2 OVATION 2 Study, which assessed IMNN-001 (100 mg/m2 administered intraperitoneally weekly) plus neoadjuvant and adjuvant chemotherapy (N/ACT) of paclitaxel and carboplatin compared to standard-of-care N/ACT alone in 112 patients with newly diagnosed advanced ovarian cancer. About Epithelial Ovarian Cancer Epithelial ovarian cancer is the sixth deadliest malignancy among women in the U.S. There are approximately 20,000 new cases of ovarian cancer every year and approximately 70% are diagnosed in advanced Stage III/IV. Epithelial ovarian cancer is characterized by dissemination of tumors in the peritoneal cavity with a high risk of recurrence (75%, Stage III/IV) after surgery and chemotherapy. Since the five-year survival rates of patients with Stage III/IV disease at diagnosis are poor (41% and 20%, respectively), there remains a need for a therapy that not only reduces the recurrence rate but also improves overall survival. The peritoneal cavity of advanced ovarian cancer patients contains the primary tumor environment and is an attractive target for a regional approach to immune modulation. About IMUNON IMUNON is a clinical-stage biotechnology company focused on advancing a portfolio of innovative treatments that harness the body's natural mechanisms to generate safe, effective and durable responses across a broad array of human diseases, constituting a differentiating approach from conventional therapies. IMUNON is developing its non-viral DNA technology across its modalities. The first modality, TheraPlas®, is developed for the gene-based delivery of cytokines and other therapeutic proteins in the treatment of solid tumors where an immunological approach is deemed promising. The second modality, PlaCCine®, is developed for the gene delivery of viral antigens that can elicit a strong immunological response. The Company's lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer that has completed multiple clinical trials including one Phase 2 clinical trial (OVATION 2). IMNN-001 works by instructing the body to produce safe and durable levels of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. Additionally, the Company has completed dosing in a first-in-human study of its COVID-19 booster vaccine (IMNN-101). The Company will continue to leverage these modalities and to advance, either directly or through partnership, the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions.

IMDELLTRA® SIGNIFICANTLY REDUCED RISK OF DEATH BY 40% IN SMALL CELL LUNG CANCER PATIENTS
Breakthrough Second-Line Treatment Demonstrated Survival Advantage over Standard-of-Care Chemotherapy Late-Breaking Data Presented at ASCO 2025 and Simultaneously Published in The New England Journal of Medicine THOUSAND OAKS, Calif., June 2, 2025 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced new interim results from the global Phase 3 DeLLphi-304 trial showing IMDELLTRA® (tarlatamab-dlle) reduced the risk of death by 40% and significantly extended median overall survival (OS) by more than five months compared to standard-of-care (SOC) chemotherapy in patients with small cell lung cancer (SCLC) who progressed on or after one line of platinum-based chemotherapy (median OS: 13.6 vs 8.3 months; hazard ratio [HR], 0.60; 95% confidence interval [CI]: 0.47, 0.77; P < 0.001). The results will be presented at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting (LBA8008) and have been published in The New England Journal of Medicine. "Small cell lung cancer is an extraordinarily aggressive and difficult-to-treat disease, and those living with SCLC often experience limited benefit with first line treatment," said Jay Bradner, M.D., executive vice president, Research and Development, at Amgen. "These data underscore IMDELLTRA's potential to transform patient outcomes and the small cell lung cancer treatment paradigm." At the planned interim analysis, DeLLphi-304 met its primary OS endpoint and key secondary progression-free survival (PFS) endpoint. Additionally, IMDELLTRA significantly improved patient-reported outcomes (PRO) for cancer-related symptoms of dyspnea and cough compared to the control arm. "The data from DeLLphi-304 mark a major milestone for people with relapsed small cell lung cancer. Tarlatamab is associated with significant improvements in both overall and progression-free survival over standard chemotherapy in patients with recurrent or progressive disease," said Charles Rudin, M.D., Ph.D., deputy director, Memorial Sloan Kettering Cancer Center. "This study also provides confirmatory data on management of potential toxicities associated with bispecific T-cell engager therapies in a large patient cohort, which is crucial to continuing to improve the experience of patients treated with these medicines." At a median follow-up of 11.2 months for IMDELLTRA and 11.7 months for the control arm, data from the global Phase 3 DeLLphi-304 clinical trial showed a median OS of 13.6 months with IMDELLTRA compared to 8.3 months with local SOC chemotherapy (HR, 0.60; 95% CI: 0.47, 0.77; P < 0.001). Median PFS was statistically significantly improved for IMDELLTRA compared to local SOC chemotherapy (median PFS: 4.2 vs 3.7 months; HR, 0.71; 95% CI: 0.59, 0.86; P < 0.001). The safety profile for IMDELLTRA in DeLLphi-304 was consistent with its known profile. In DeLLphi-304, lower rates of grade 3 or higher treatment-related adverse events (TRAEs) occurred with IMDELLTRA versus the control arm (27% vs 62%) and discontinuations due to TRAEs were lower with IMDELLTRA compared to the control arm (3% vs 6%). The most common grade 3 or greater TRAEs were neutropenia (4%) and lymphopenia (4%) with IMDELLTRA and anemia (28%) and neutropenia (22%) with local SOC chemotherapy. Cytokine release syndrome (CRS) with IMDELLTRA primarily occurred after receipt of one of the first two doses and was primarily low grade (42% Grade 1; 13% Grade 2; 1% Grade 3) and manageable. No Grade 4 or Grade 5 CRS events were reported. CRS profiles following the first two doses of IMDELLTRA, including incidence, severity, outcome, time to intervention and time to resolution, were similar among patients who were monitored for 6 to 8 hours (n=43) and those who were monitored for 48 hours (n=209). DeLLphi-304 is a global Phase 3, randomized, controlled, open-label clinical trial evaluating the efficacy and safety of IMDELLTRA as a treatment for patients living with SCLC who progressed on or after a single line of platinum-based chemotherapy.1 Five hundred and nine patients were randomized to receive either IMDELLTRA or local SOC chemotherapy (topotecan in all countries except Japan; lurbinectedin in the U.S., Canada, Australia, Singapore, Korea; and amrubicin in Japan).1,2 The primary outcome measure of the trial is OS.1 Key secondary outcome measures include PFS and PROs including disease-related symptoms, physical function and quality of life.1 DeLLphi-304 is intended to serve as the confirmatory trial for IMDELLTRA's accelerated approval for the treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC) with disease progression on or after platinum-based chemotherapy. About IMDELLTRA® (tarlatamab-dlle)IMDELLTRA is a first-in-class targeted immunotherapy engineered by Amgen researchers to bind to both DLL3 on tumor cells and CD3 on T cells, thereby activating T cells to kill DLL3-expressing SCLC cells. This results in the formation of a cytolytic synapse with lysis of the cancer cell.3,4 DLL3 is a protein that is expressed on the surface of SCLC cells in ~85-96% of patients with SCLC, but is minimally expressed on healthy cells, making it an exciting target.5,6 IMDELLTRA® (tarlatamab-dlle) U.S. IndicationIMDELLTRA® (tarlatamab-dlle) is indicated for the treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC) with disease progression on or after platinum-based chemotherapy.

Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise. No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for us to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and we expect similar variability in the future. Even when clinical trials are successful, regulatory authorities may question the sufficiency for approval of the trial endpoints we have selected. We develop product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as we may have believed at the time of entering into such relationship. Also, we or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market. Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions, including those resulting from geopolitical relations and government actions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. An outbreak of disease or similar public health threat, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to collaborate with or acquire other companies, products or technology, and to integrate the operations of companies or to support the products or technology we have acquired, may not be successful. There can be no guarantee that we will be able to realize any of the strategic benefits, synergies or opportunities arising from the Horizon acquisition, and such benefits, synergies or opportunities may take longer to realize than expected. We may not be able to successfully integrate Horizon, and such integration may take longer, be more difficult or cost more than expected. A breakdown, cyberattack or information security breach of our information technology systems could compromise the confidentiality, integrity and availability of our systems and our data. Our stock price is volatile and may be affected by a number of events. Our business and operations may be negatively affected by the failure, or perceived failure, of achieving our sustainability objectives.

Jazz Pharmaceuticals Reports Clinically Meaningful Long-Term Median Overall Survival Data for Ziihera® (zanidatamab-hrii) in First-Line HER2-Positive Metastatic Gastroesophageal Adenocarcinoma at ASCO 2025
Phase 2 trial results continue to show clinically meaningful efficacy and durable responses, including 36.5-month median overall survival after four years of follow-up, with a manageable safety profile Findings presented today at ASCO 2025 and concurrently published in The Lancet Oncology For U.S. media and investors only DUBLIN, June 2, 2025 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced long-term data, including the first report of median overall survival (OS) from the Phase 2 trial evaluating Ziihera® (zanidatamab-hrii), a dual HER2-targeted bispecific antibody, in combination with chemotherapy for the investigational use in first-line HER2-positive (IHC 3+ or IHC 2+/FISH+) locally advanced nonresectable gastroesophageal adenocarcinoma (mGEA). The data were featured as a rapid oral presentation at the American Society of Clinical Oncology (ASCO) Annual Meeting, and the results were concurrently published in The Lancet Oncology. Among 41 patients with centrally confirmed HER2-positive tumors, treatment with Ziihera in combination with physician's choice of chemotherapy resulted in a median progression-free survival (PFS) of 15.2 months [95% CI: 9.5, 33.4], and a median overall survival (OS) of 36.5 months [95% CI: 23.6, not estimable (NE)]. Median PFS remained stable with the additional four-year follow-up, consistent with previously reported results. Among all 46 patients in the study with HER2-expressing mGEA, median PFS was 12.5 months [95% CI: 8.2, 21.8], and median OS also reached 36.5 months [95% CI: 23.6, NE], with the longest observed survival at 57.9 months (censored at data cutoff). Long-term follow-up also demonstrated low discontinuation rates, with no new safety signals observed. "Gastroesophageal adenocarcinoma remains a highly aggressive cancer with a poor prognosis, even with currently available treatment options," said Dr. Elena Elimova, lead trial investigator and a medical oncologist at Princess Margaret Cancer Centre, Toronto, Canada. "The long-term survival outcomes presented today at ASCO demonstrate the sustained antitumor activity achieved with zanidatamab plus chemotherapy over four years of follow-up. These results are especially encouraging given the high unmet need for better first-line treatment options for this patient population." "These long-term survival data from our Phase 2 trial build on previously reported results and further strengthen our belief in Ziihera as a transformative treatment option for patients with HER2-positive disease," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development, and chief medical officer of Jazz Pharmaceuticals. "An estimated median overall survival of 36.5 months in this patient cohort is very encouraging given recent observations with standard of care regimens in similar populations, where median survival has typically ranged from 15 to 20 months. The sustained 15.2-month progression-free survival in the centrally confirmed HER2-positive subgroup after four years is a meaningful indicator of durable clinical benefit. We look forward to the top line results of the pivotal Phase 3 HERIZON-GEA-01 trial later this year and remain committed to advancing Ziihera across multiple tumor types." Phase 2 mGEA Trial Results The data include four-year follow-up and the first report of median OS from an ongoing, open-label Phase 2 trial (NCT03929666) evaluating Ziihera in combination with chemotherapy as a first-line treatment for patients with HER2-expressing mGEA, which includes gastric, esophageal and gastroesophageal junction (GEJ) adenocarcinomas. Patients had not received prior HER2-targeted agents nor systemic treatment for mGEA. A total of 46 patients with HER2-expressing mGEA (41 patients with centrally confirmed HER2-positive mGEA) were enrolled from 14 sites across the United States, Canada and South Korea. Patients received Ziihera with physician's choice of chemotherapy, including fluoropyrimidine maintenance regimens. Chemotherapy-based regimens remain the current standard first-line treatment for mGEA. The longer-term data (median duration of follow-up of 48 months [range, 29-59]) demonstrate the promising antitumor activity of Ziihera combined with chemotherapy as a first-line treatment for HER2-positive mGEA. In a post-hoc subgroup analysis of the 41 treated patients with centrally confirmed HER2-positive tumors, median PFS was 15.2 months [95% CI: 9.5, 33.4], and median OS was 36.5 months [95% CI: 23.6, NE]. These survival outcomes were consistent with prior analyses, with PFS durability maintained at the four-year follow-up. The confirmed objective response rate (cORR), the study's primary endpoint, was 83.8% [95% CI: 68.0, 93.8], and median duration of response (DOR) was 20.4 months [95% CI: 8.3, 44.1]. These results further support the observed clinical benefit in this centrally confirmed population. Among all 46 patients in the study, median PFS was 12.5 months [95% CI: 8.2, 21.8], and the estimated 24-month PFS rate was 31% [95% CI: 17%, 46%]. Median OS was also 36.5 months [95% CI: 23.6, NE], with an estimated 24-month OS rate of 65% [95% CI: 49%, 77%]. The cORR was 76.2% [95% CI: 60.5, 87.9], and median DOR was 18.7 months [95% CI: 10.4, 44.1]. With additional follow-up, the safety and tolerability profile of Ziihera plus chemotherapy showed low discontinuation rates, with no new safety signals identified. Diarrhea (39%) and hypokalemia (22%) were the most common Grade 3-4 treatment-related adverse events (TRAEs); the incidence of Grade 3 diarrhea was reduced from 52% to 24% for patients enrolled after the implementation of mandated antidiarrheal prophylaxis. There were no treatment-related deaths. Five patients discontinued Ziihera due to TRAEs. Ongoing Phase 3 TrialThe Phase 3 randomized clinical trial, HERIZON-GEA-01 (NCT05152147), evaluating Ziihera in combination with standard of care chemotherapy with and without the addition of a PD-1 agent as a first-line treatment for HER2-expressing mGEA is currently underway. This is an events-based trial, and top-line results are expected to read out in the second half of 2025. About Gastroesophageal AdenocarcinomaGastroesophageal adenocarcinoma (GEA) is the fifth most common cancer worldwide, and approximately 20% of patients have HER2-positive disease.i,ii,iii HER2-positive GEA has high morbidity and mortality, and patients are urgently in need of new treatment options. The overall prognosis for patients with GEA remains poor, with a global five-year survival rate of less than 30 percent for gastric cancer and about 19 percent for About Ziihera® (zanidatamab-hrii) Ziihera (zanidatamab-hrii) is a bispecific HER2-directed antibody that binds to two extracellular sites on HER2. Binding of zanidatamab-hrii with HER2 results in internalization leading to a reduction in HER2 expression of the receptor on the tumor cell surface. Zanidatamab-hrii induces complement-dependent cytotoxicity (CDC), antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). These mechanisms result in tumor growth inhibition and cell death in vitro and in vivo.v In the United States, Ziihera is indicated for the treatment of adults with previously treated, unresectable or metastatic HER2-positive (IHC 3+) biliary tract cancer (BTC), as detected by an FDA-approved test.v The U.S. Food and Drug Administration (FDA) granted accelerated approval for this indication based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). v Zanidatamab is being developed in multiple clinical trials as a targeted treatment option for patients with solid tumors that express HER2. Zanidatamab is being developed by Jazz and BeiGene, Ltd. (BeiGene) under license agreements from Zymeworks, which first developed the molecule. The FDA granted Breakthrough Therapy designation for zanidatamab development in patients with previously treated HER2 gene-amplified BTC, and two Fast Track designations for zanidatamab: one as a single agent for refractory BTC and one in combination with standard-of-care chemotherapy for 1L gastroesophageal adenocarcinoma (GEA). Additionally, zanidatamab has received Orphan Drug designations from FDA for the treatment of BTC and GEA, as well as Orphan Drug designation from the European Medicines Agency for the treatment of BTC and gastric cancer. Important Safety Information for ZIIHERA WARNING: EMBRYO-FETAL TOXICITYExposure to ZIIHERA during pregnancy can cause embryo-fetal harm. Advise patientsof the risk and need for effective contraception. WARNINGS AND PRECAUTIONS Embryo-Fetal Toxicity ZIIHERA can cause fetal harm when administered to a pregnant woman. In literature reports, use of a HER2-directed antibody during pregnancy resulted in cases of oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death. Verify the pregnancy status of females of reproductive potential prior to the initiation of ZIIHERA. Advise pregnant women and females of reproductive potential that exposure to ZIIHERA during pregnancy or within 4 months prior to conception can result in fetal harm. Advise females of reproductive potential to use effective contraception during treatment with ZIIHERA and for 4 months following the last dose of ZIIHERA. Left Ventricular Dysfunction ZIIHERA can cause decreases in left ventricular ejection fraction (LVEF). LVEF declined by >10% and decreased to <50% in 4.3% of 233 patients. Left ventricular dysfunction (LVD) leading to permanent discontinuation of ZIIHERA was reported in 0.9% of patients. The median time to first occurrence of LVD was 5.6 months (range: 1.6 to 18.7). LVD resolved in 70% of patients. Assess LVEF prior to initiation of ZIIHERA and at regular intervals during treatment. Withhold dose or permanently discontinue ZIIHERA based on severity of adverse reactions. The safety of ZIIHERA has not been established in patients with a baseline ejection fraction that is below 50%. Infusion-Related Reactions ZIIHERA can cause infusion-related reactions (IRRs). An IRR was reported in 31% of 233 patients treated with ZIIHERA as a single agent in clinical studies, including Grade 3 (0.4%), and Grade 2 (25%). IRRs leading to permanent discontinuation of ZIIHERA were reported in 0.4% of patients. IRRs occurred on the first day of dosing in 28% of patients; 97% of IRRs resolved within one day. Prior to each dose of ZIIHERA, administer premedications to prevent potential IRRs. Monitor patients for signs and symptoms of IRR during ZIIHERA administration and as clinically indicated after completion of infusion.
