OXFORD, England, March 28, 2025 /PRNewswire/ -- Ultromics, a pioneer in AI-driven cardiology solutions, has unveiled the latest enhancement to EchoGo® Heart Failure: the introduction of a first-of-its-kind AI-powered probability scoring system for assessing heart failure with preserved ejection fraction (HFpEF). This innovation marks a groundbreaking development the use of deep learning to improve the detection of this often underrecognized condition. Continue Reading Ultromics Introduces AI-Powered Probability Scoring on EchoGo® Heart Failure for Enhanced HFpEF Diagnosis EchoGo® Heart Failure remains the first and only AI platform capable of identifying HFpEF from a routine echocardiogram. The new probability scoring system builds upon this unique capability by generating a continuous score of the likelihood of disease, which provides a more nuanced diagnostic assessment of HFpEF, minimizing uncertainty and enhancing clinical decision-making. Additionally, the platform continues to support the detection of other critical heart conditions, such as cardiac amyloidosis, helping clinicians in the early identification of underlying causes of heart failure. "The introduction of the probability scoring feature into the EchoGo® Heart Failure platform represents a pivotal step forward in heart failure detection and patient risk stratification," said Ross Upton, PhD, Founder, CEO, and Chief Scientific Officer of Ultromics. "By delivering a precise probability score, EchoGo® Heart Failure enables clinicians to assess a patient's likelihood of disease, allowing for more confident decision-making". Real-World Impact and Clinical Validation The updated EchoGo® Heart Failure platform has been rigorously validated in a study at Beth Israel Deaconess Medical Center (BIDMC), a Harvard Medical School teaching hospital, and other leading clinical sites. This study focused on real-world, complex cases, including patients with multiple overlapping comorbidities, such as a combination of hypertension and diabetes, where traditional diagnostic models may struggle to distinguish between cases and controls effectively. Results revealed that the AI-powered probability scoring system provides substantial added information, accurately aiding in the diagnosis of HFpEF, the likelihood of disease, and patient outcomes. The platform demonstrated higher sensitivity in detecting HFpEF and improved differentiation between HFpEF and clinically complex controls at risk or with possible—but not confirmed—HFpEF, compared to standard clinical practice.[1] The new probability scoring feature also associates positively to patient outcomes: patients flagged by EchoGo® Heart Failure as high-risk showed a two-fold increase in the likelihood of heart failure hospitalizations and mortality, highlighting the potential of AI to inform timely interventions that could improve patient management.[1] Using all available clinical information with EchoGo® Heart Failure led to a 33% improvement in correctly managing patients with HFpEF, compared to relying solely on the H2FPEF score.[1] When compared to standard clinical practice, like H2FPEF and HFA-PEFF, EchoGo® Heart Failure demonstrated fewer indeterminate classifications, reducing diagnostic uncertainty—a common issue with traditional models—leading to confident diagnoses in over 80% of patients.[1] "By integrating this advanced AI-powered tool into routine echocardiograms, we are enhancing our ability to detect HFpEF with greater certainty," said Jordan Strom, lead study author and cardiologist at Beth Israel Deaconess Medical Center, a teaching hospital of Harvard Medical School. "This is especially important in a disease as heterogeneous as HFpEF. Our work suggests that the combination of clinical scores and AI may improve certainty about the diagnosis of HFpEF and suggests a possible path forward for the integration of AI into clinical practice. This approach can ultimately help ensure timely recognition and treatment of HFpEF and facilitate clinical workflows." Introducing the Probability Score Enhancement HFpEF remains one of the most challenging forms of heart failure to diagnose partly due to the complex interplay between multiple clinical and echocardiographic parameters. Accurate detection requires the careful integration of these variables, which can be discordant or indeterminate in some patients. As a result, HFpEF is often underdiagnosed or misdiagnosed, delaying appropriate care. The advanced capabilities of EchoGo® Heart Failure are designed to tackle these challenges. Leveraging deep learning algorithms, the platform generates a continuous risk score, offering greater granularity than binary outputs. This continuous scoring system allows for a more nuanced assessment of HFpEF likelihood, minimizing diagnostic uncertainty and enhancing clinical decision-making. New features of EchoGo® Heart Failure include: Probability-Based Scoring: The AI evaluates sequences of echocardiogram frames and assigns scores reflecting patterns consistent with HFpEF, providing valuable insights for clinical decision-making. Uncertainty Estimates: Each score is accompanied by an uncertainty estimate, ensuring that uncertain predictions are flagged for further review, reducing false positives or negatives. Comparative Analysis Visualization: Clinicians can compare a patient's results against a large reference population of HFpEF and non-HFpEF cases, supporting objective and informed assessments. EchoGo® Heart Failure with probability scoring is FDA Device Breakthrough cleared and is now available to healthcare professionals as part of the platform.

Median overall survival not yet reached with projected improvement of more than one year versus osimertinib RARITAN, NJ, USA I March 26, 2025 I Johnson & Johnson (NYSE: JNJ ) today announced results for the gold standard endpoint in cancer treatment of overall survival (OS) from the Phase 3 MARIPOSA study. Head-to-head comparison data versus osimertinib showed RYBREVANT ® (amivantamab-vmjw) plus LAZCLUZE™ (lazertinib) significantly extended OS in the first-line treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor ( EGFR ) exon 19 deletions (ex19del) or L858R substitution mutations. Median OS is projected to exceed one year beyond the median of three years observed with osimertinib and has not yet been reached. This is the first and only study to show a statistically significant and clinically meaningful OS improvement over osimertinib. New compelling data were presented during a proffered paper session at the 2025 European Lung Cancer Congress (ELCC) (Abstract #4O). 1 “The survival curve tells a clear story. RYBREVANT plus LAZCLUZE helps patients live longer, and the benefit keeps growing over time,” said trial investigator Professor Nicolas Girard*, M.D., Ph.D., Head of Medical Oncology, Institut Curie, and Professor of Thoracic Oncology and Respiratory Medicine at the Paris-Saclay University, France. “We see the gap between the survival curves continue to widen, which is exactly what we want to see in lung cancer treatment to improve outcomes for patients. These results reinforce that we are entering a new era for EGFR -mutated non-small cell lung cancer; with this evidence in hand, we need to ensure every patient gets the most effective treatment in the first line for the best possible chance at longer survival.” Unlike progression-free survival (PFS), which tracks the time a treatment keeps a patient’s cancer from progressing, OS helps patients understand the impact therapy could have on the ability to live longer from the start of treatment. Extending life expectancy is the most meaningful indicator of a treatment’s impact. At a median follow-up of 37.8 months, patients treated with the chemotherapy-free regimen of first-line RYBREVANT ® plus LAZCLUZE™ had a significantly longer OS compared to those receiving osimertinib (hazard ratio [HR], 0.75; 95 percent confidence interval [CI], 0.61-0.92; nominal P<0.005). Median OS for RYBREVANT ® plus LAZCLUZE™ has not yet been reached, indicating that survival benefits continue to extend beyond the measured follow-up period (not reached [NR]; 95 percent CI, 42.9-NR). Comparatively, median OS for osimertinib-treated patients was 36.7 months (95 percent CI, 33.4-41.0) and consistent with prior studies with osimertinib. Fifty-six percent of patients treated with RYBREVANT ® and LAZCLUZE™ were alive at three and a half years compared to 44 percent of patients on osimertinib. Projections based on survival data suggest RYBREVANT ® plus LAZCLUZE™ could extend median OS by at least 12 months compared to osimertinib. 1 The RYBREVANT ® combination also prolonged multiple secondary endpoints vs osimertinib, including intracranial PFS, intracranial duration of response (DOR) and intracranial overall response rate (ORR). Notably, RYBREVANT ® plus LAZCLUZE™ prolonged time to symptomatic progression (TTSP) – the time from treatment randomization to the onset of lung cancer symptoms – by more than 14 months compared to osimertinib (43.6 months vs 29.3 months; HR, 0.69; 95 percent CI, 0.57–0.83; nominal P<0.001). This is a key patient-centered measure, highlighting how long quality of life can be preserved before lung cancer symptoms emerge. 1 “Right now, only twenty percent of patients with EGFR- positive NSCLC survive beyond five years. These MARIPOSA results suggest that RYBREVANT plus LAZCLUZE can change this dire statistic that has been stagnant for far too long,” said Joshua Bauml, M.D., Vice President, Lung Cancer Disease Area Stronghold Leader, Johnson & Johnson Innovative Medicine. “This regimen isn’t just extending survival, it’s offering hope. By using RYBREVANT plus LAZCLUZE first, we’re delaying the need for chemotherapy and giving patients and their families more time.” The safety profile of RYBREVANT ® plus LAZCLUZE™ was consistent with the primary analysis, with adverse event (AE) rates comparable to other RYBREVANT ® regimens. No new safety signals were identified with the additional longer-term follow-up. Most AEs occurred early during RYBREVANT ® and LAZCLUZE™ treatment. 1 RYBREVANT ® research findings suggest that implementing prophylactic measures during the first four months of RYBREVANT ® and LAZCLUZE™ treatment may significantly reduce the risk of skin reactions, infusion-related reactions and venous thromboembolic events. 2,3,4 The MARIPOSA study met its primary endpoint in October 2023, showing a statistically significant and clinically meaningful improvement in PFS compared to osimertinib. RYBREVANT ® plus LAZCLUZE™ is approved in the United States, Europe and other markets around the world for patients with first-line EGFR -mutated NSCLC. These OS results will be shared with health authorities globally. About the MARIPOSA Study MARIPOSA ( NCT04487080 ), which enrolled 1,074 patients, is a randomized, Phase 3 study evaluating RYBREVANT ® in combination with LAZCLUZE™ versus osimertinib and versus LAZCLUZE™ alone in first-line treatment of patients with locally advanced or metastatic NSCLC with EGFR ex19del or substitution mutations. The primary endpoint of the study is PFS (using RECIST v1.1 guidelines**) as assessed by BICR. Secondary endpoints include OS, ORR, DOR, PFS2 and intracranial PFS. 5 About RYBREVANT ® RYBREVANT ® (amivantamab-vmjw), a fully-human bispecific antibody targeting EGFR and MET with immune cell-directing activity, is approved in the U.S. , Europe and other markets around the world as monotherapy for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy. 6 RYBREVANT ® is approved in the U.S. , Europe and other markets around the world in combination with chemotherapy (carboplatin and pemetrexed) for the first-line treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test. RYBREVANT ® is approved in the U.S., Europe and other markets around the world in combination with LAZCLUZE™ (lazertinib) for the first-line treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations, as detected by an FDA-approved test. RYBREVANT ® is approved in the U.S. , Europe and other markets around the world in combination with chemotherapy (carboplatin-pemetrexed) for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or L858R substitution mutations, whose disease has progressed on or after treatment with an EGFR TKI. In February 2025, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) recommended the approval of SC amivantamab and LAZCLUZE™ in Europe for the first-line treatment of adult patients with advanced NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations, and as a monotherapy for the treatment of adult patients with advanced NSCLC with activating EGFR exon 20 insertion mutations after failure of platinum-based therapy.

About LAZCLUZE™ In 2018, Janssen Biotech, Inc., entered into a license and collaboration agreement with Yuhan Corporation for the development of LAZCLUZE™ (marketed as LECLAZA in South Korea). LAZCLUZE™ is an oral, third-generation, brain-penetrant EGFR TKI that targets both the T790M mutation and activating EGFR mutations while sparing wild-type EGFR . An analysis of the efficacy and safety of LAZCLUZE™ from the Phase 3 LASER301 study was published in The Journal of Clinical Oncology in 2023. 21 About Non-Small Cell Lung Cancer Worldwide, lung cancer is one of the most common cancers, with NSCLC making up 80 to 85 percent of all lung cancer cases. 22,23 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. 24 Among the most common driver mutations in NSCLC are alterations in EGFR , which is a receptor tyrosine kinase controlling cell growth and division. 25 EGFR mutations are present in 10 to 15 percent of Western patients with NSCLC with adenocarcinoma histology and occur in 40 to 50 percent of Asian patients. 22,23,26,27,28,29 EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations. 30 The five-year survival rate for all people with advanced NSCLC and EGFR mutations treated with EGFR tyrosine kinase inhibitors (TKIs) is less than 20 percent. 31,32 EGFR exon 20 insertion mutations are the third most prevalent activating EGFR mutation. 33 Patients with EGFR exon 20 insertion mutations have a real-world five-year overall survival (OS) of eight percent in the frontline setting, which is worse than patients with EGFR ex19del or L858R mutations, who have a real-world five-year OS of 19 percent. 34 Please read full Prescribing Information for RYBREVANT ® .

QMG (Quantitative Myasthenia Gravis) is a 13-item assessment by a clinician that quantifies MG disease severity. The total QMG score ranges from 0 to 39, where higher scores indicated greater disease severity. b. MG-ADL (Myasthenia Gravis – Activities of Daily Living) provides a rapid clinical assessment of the patient's recall of symptoms impacting activities of daily living, with a total score range of 0 to 24; a higher score indicates greater symptom severity. ABOUT GENERALIZED MYASTHENIA GRAVIS (gMG) Myasthenia gravis (MG) is an autoantibody disease in which the immune system mistakenly makes antibodies (e.g., anti-acetylcholine receptor [AChR], anti-muscle-specific tyrosine kinase [MuSK] or anti-low density lipoprotein-related protein 4 [LRP4]), which target proteins at the neuromuscular junction and can block or disrupt normal signaling from nerves to muscles, thus impairing or preventing muscle contraction.4,5,6 The disease impacts an estimated 700,000 people worldwide.4 The disease affects both men and women and occurs across all ages, racial and ethnic groups, but most frequently starts in young women and older men.7 Roughly 50 percent of individuals diagnosed with MG are women, and about one in five of those women are of child-bearing potential.8,9,10Approximately 10 to 15% of new cases of MG are diagnosed in adolescents (12 – 17 years of age).11,12,13 Among juvenile MG patients, girls are affected more often than boys with over 65% of pediatric MG cases in the U.S. diagnosed in girls.14,15,16 Initial disease manifestations are usually ocular but approximately 85 percent of MG patients experience additional advancements to the disease manifestations—referred to as generalized myasthenia gravis (gMG). This is characterized by severe muscle weakness and difficulties in speech and swallowing.17,18,19,20,21 Approximately 100,000 individuals in the U.S. are living with gMG.22 Vulnerable gMG populations, such as pediatric patients, have more limited therapeutic options.23 Currently, SOC treatments for adolescents with gMG are extrapolated from adult trials.13 Other than symptomatic treatments, there are no approved FcRn blockers for adolescents with gMG in the United States.13 ABOUT THE PHASE 3 VIVACITY-MG3 STUDY The Phase 3 Vivacity-MG3 study (NCT04951622) was specifically designed to measure sustained efficacy and safety with consistent dosing in this unpredictable chronic condition where unmet need remains high. Antibody positive or negative adult gMG patients with insufficient response (MG-ADL ≥6) to ongoing SOC therapy were identified and 199 patients, 153 of whom were antibody positive, enrolled in the 24-week double-blind placebo-controlled trial.24,25 Randomization was 1:1, nipocalimab plus current SOC (30 mg/kg IV loading dose followed by 15 mg/kg every two weeks) or placebo plus current SOC.24 Baseline demographics were balanced across arms (77 nipocalimab, 76 placebo).24 The primary endpoint of the study was mean change in MG-ADLb score from baseline over Weeks 22, 23 and 24 in antibody positive patients. A key secondary endpoint included change in QMG score. Long-term safety and efficacy were further assessed in an ongoing open-label extension (OLE) phase.25 ABOUT NIPOCALIMAB Nipocalimab is an investigational monoclonal antibody, designed to bind with high affinity to block FcRn and reduce levels of circulating immunoglobulin G (IgG) antibodies potentially without impact on other immune functions. This includes autoantibodies and alloantibodies that underlie multiple conditions across three key segments in the autoantibody space including Rare Autoantibody diseases, Maternal Fetal diseases mediated by maternal alloantibodies and Rheumatic diseases.3,25,26,27,28,29,30,31,32 Blockade of IgG binding to FcRn in the placenta is also believed to limit transplacental transfer of maternal alloantibodies to the fetus.33,34 The U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) have granted several key designations to nipocalimab including: U.S. FDA Fast Track designation in HDFN and warm autoimmune hemolytic anemia (wAIHA) in July 2019, gMG in December 2021, FNAIT in March 2024 and Sjögren's disease (SjD) in March 2025 U.S. FDA Orphan drug status for wAIHA in December 2019, HDFN in June 2020, gMG in February 2021, chronic inflammatory demyelinating polyneuropathy (CIDP) in October 2021 and FNAIT in December 2023 U.S. FDA Breakthrough Therapy designation for HDFN in February 2024 and for Sjögren's disease in November 2024 U.S. FDA granted Priority Review in gMG in Q4 2024 EU EMA Orphan medicinal product designation for HDFN in October 2019 ABOUT JOHNSON & JOHNSON At Johnson & Johnson, we believe health is everything.
