Signatera Data From I-SPY 2 Trial to Be Presented at ESMO Breast Annual Congress
AUSTIN, Texas--(BUSINESS WIRE)-- Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and precision medicine, will present multiple datasets in breast cancer together with its collaborators at the 2025 ESMO Breast Cancer Annual Congress in Munich, Germany, taking place from May 14-17, 2025.
Results from the I-SPY 2 clinical trial, sponsored and operated by Quantum Leap Healthcare Collaborative, will be shared in a mini-oral presentation on May 16, 2025. The report includes data from 712 patients with early-stage, high-risk breast cancer, and it evaluates the association of distant recurrence free survival (DRFS) with ctDNA concentration at diagnosis, before receiving neoadjuvant systemic therapy and curative-intent surgery. Key highlights include:
Signatera positive patients at diagnosis had 3x higher risk of recurrence than Signatera negative patients (HR 3.1, p< 0.001%), though the risk can be significantly reduced based on response to subsequent therapy.
Patients who were Signatera negative at diagnosis had extremely good outcomes.
Among patients who were Signatera positive at diagnosis, higher ctDNA quantities at the time of diagnosis were significantly correlated with a higher risk of recurrence. However, effective treatment can affect ctDNA levels as well as pathologic response status, both of which further refine risk of recurrence. This is the first time that pre-treatment absolute ctDNA quantity has been shown to correlate with clinical outcomes in breast cancer.
Among all clinicopathologic risk factors available at diagnosis, a multivariate analysis identified Signatera status as the most significant factor in predicting DRFS, regardless of disease subtype (p<0.001). DRFS prediction can be further refined by integrating additional variables before, during, and after treatment, including ctDNA dynamics.
'The I-SPY 2 trial is uncovering insights that may allow us to tailor treatment plans for breast cancer patients based on their individual genomic profiles and better identify patients who may be more likely to experience adverse outcomes,' said Laura Esserman, M.D., MBA, and Laura van 't Veer, Ph.D., professors at the University of California, San Francisco, and principal investigators of the I-SPY 2 study. 'Our hope is that these findings will encourage future interventional trials in breast cancer, specifically in the neoadjuvant setting.'
'Signatera was able to predict excellent clinical outcomes in a high risk population at the time of diagnosis,' said Angel Rodriguez, M.D., medical director, oncology at Natera. 'This may give rise to new protocols, evaluating whether some patients can avoid chemotherapy or other intensive treatments, if they test Signatera-negative at diagnosis.'
Natera will present an additional three abstracts at the ESMO Breast conference, highlighting real-world evidence and genomic landscaping from its multi-modal database of de-identified clinical and genomic data in over 200,000 early- and late-stage cancer patients.

Drug maker Indivior joins the flight from London share listings
Drug maker Indivior has become the latest major UK listed company to scrap its London share trading. The pharmaceuticals company, which has its UK headquarters in Slough, said it planned to cancel its secondary listing in London. Indivior only moved its primary listing to Nasdaq last June and now wants to sever all share trading links with the City. The move comes just a year after Invidior's board said it planned to keep the London listing "for as long as it is considered to be in the best interests of Indivior and its shareholders as a whole." Reasons given for scrapping the London listing following a review include the fact that 80% of the company's revenue is generated in America; trading on Nasdaq accounts for approximately 75% of total volumes across both exchanges; more than 70% of the share are now held by investors located in the U.S; and the elimination of 'the cost and complexity of maintaining a secondary listing.' Another major factor is that the company's biggest selling drug Sublocade, a treatment for helping opioid addicts reduce their dependence, has its biggest market in the US. Last year Sublocade accounted for $756 million of the company's total $1.2 billion sales. Indivior was spun out of its former parent company, the consumer products giant Reckitt Benckizer in 2014 as a free standing London listed company. The Virginia based company's chair David Wheadon, said:"We are pleased to announce this key milestone for Indivior following our evaluation period. A single primary listing on Nasdaq best reflects the profile of Indivior's business. 'We appreciate the support received from shareholders for this initiative and look forward to capitalizing on the expected benefits of this move, including reductions in cost and complexity." London has suffered a major outflow of listed companies over recent years in a blow to the prestige of the City. A total of 88 firms delisted or transferred their primary listing from the London Stock Exchange last year, the highest number since the financial crisis of 2008, according to auditor EY. Only 18 companies came on to the London market last year as the vital flow of small and growing businesses raising capital by listing their shares on the London stock market dried up.

Protagonist and Takeda Announce ASCO Plenary Presentation Highlighting Full 32-Week Results from Phase 3 VERIFY Study of Rusfertide, Showing Reductions in Phlebotomy, Improved Hematocrit Control in Polycythemia Vera
Osaka, Japan & Cambridge, Mass., Newark, Calif., United States: Rusfertide plus current standard of care more than doubled clinical response rates across high- and low-risk PV groups, significantly reducing phlebotomy eligibility compared to placebo plus current standard of care, which was the primary endpoint All key secondary endpoints met with statistical significance, including a nearly three-fold reduction in the proportion of patients requiring phlebotomy and a four-fold improvement in hematocrit control in rusfertide arm compared to placebo arm, as well as improvements in patient-reported outcomes No serious adverse events considered related to rusfertide were reported Rusfertide has received Orphan Drug designation and Fast Track designation from the U.S. FDA Protagonist Therapeutics, Inc. ('Protagonist') (NASDAQ:PTGX) and Takeda (TSE:4502/NYSE:TAK) announced detailed results from the Phase 3, randomized, placebo-controlled VERIFY study evaluating rusfertide in patients with polycythemia vera (PV), which met the primary and all key secondary endpoints. The data will be presented as a late-breaking oral presentation at the 61st American Society of Clinical Oncology (ASCO) Annual Meeting Plenary Session (LBA3) at 2:09 pm CDT today. PV is characterized by overproduction of red blood cells (erythrocytosis), which may increase blood viscosity, or thickness, potentially resulting in life threatening thrombotic events such as stroke, deep vein thrombosis and pulmonary embolism. People with PV can experience burdensome symptoms, including severe fatigue, difficulty in concentrating, night sweats and pruritus, which may negatively impact their daily functioning and quality of life. Hematocrit is the ratio of red blood cells to total amount of blood in the body. Achieving and maintaining controlled hematocrit levels of <45% is the primary treatment goal in PV to prevent thrombotic events and alleviate symptoms, but many patients still experience uncontrolled hematocrit levels with current standard of care treatments. Rusfertide, an investigational, first-in-class hepcidin mimetic peptide therapeutic, is under evaluation in the Phase 3 VERIFY study for its potential to regulate iron homeostasis and red blood cell production to control hematocrit levels in patients with PV. In the study, patients dependent on frequent phlebotomy, with or without treatment with cytoreductive therapy, were randomized to receive once-weekly rusfertide or placebo, as an add-on to current standard of care treatment. 'PV poses significant challenges for patients, including debilitating symptoms and the risk of serious thrombotic events, and hematocrit control is crucial to improving patient outcomes. The VERIFY study demonstrated that treatment with rusfertide controls hematocrit levels in phlebotomy-dependent patients, including patients receiving cytoreductive therapies,' said Dr. Andrew T. Kuykendall, M.D., VERIFY Lead Investigator and Associate Member in the Department of Hematology at Moffitt Cancer Center. 'These results suggest rusfertide has the potential to become part of the standard of care treatment for patients with PV.' The study met its primary endpoint, which was the proportion of patients achieving a clinical response, defined as the absence of phlebotomy eligibility during study Weeks 20-32. Study results demonstrated 76.9% of patients treated with rusfertide plus current standard of care achieved a clinical response, compared to 32.9% in the placebo plus current standard of care group (p<0.0001).1 The response observed in the rusfertide arm was consistent across subgroups, regardless of risk status or type of concurrent cytoreductive therapy.1 In addition, all key secondary endpoints met statistical significance in favor of the rusfertide arm compared to the placebo arm in the VERIFY study, as follows: The mean number of phlebotomies was 0.5 phlebotomies per patient for those treated with rusfertide plus current standard of care compared to 1.8 phlebotomies per patient for those treated with placebo plus current standard of care during Weeks 0-32 (p<0.0001). 1 Only 27% of patients treated with rusfertide plus current standard of care required phlebotomy between Weeks 0-32, compared to 78% of patients who received placebo plus current standard of care. The mean number of phlebotomies during Weeks 0-32 in the rusfertide arm was reduced across subgroups, including risk status and use of concurrent cytoreductive therapy, versus the placebo arm. 62.6% of patients treated with rusfertide plus current standard of care maintained hematocrit levels below 45% versus 14.4% treated with placebo plus current standard of care (p<0.0001). 1 Rusfertide also showed statistically significant improvements in mean change from baseline to Week 32 in PROMIS Fatigue2 (p<0.03) and the MFSAF Total Symptom Score3 (p<0.03). Rusfertide is the first investigational therapy to prospectively demonstrate a statistically significant improvement in these patient-reported outcomes (PROs) of fatigue and symptom burden in patients with PV.1 Rusfertide was generally well tolerated. The majority of adverse events were low grade and non-serious and no serious adverse events considered related to rusfertide were reported. There was no evidence of increased risk of cancer in patients treated with rusfertide plus current standard of care compared to patients treated with placebo plus current standard of care at the time of the primary analysis. Cancer events were reported in one patient in the rusfertide arm (0.7%) and in seven patients in the placebo arm (4.8%). The most common treatment-emergent adverse events were localized injection site reactions (55.9%), anemia (15.9%) and fatigue (15.2%).1 'These findings underscore rusfertide's potential as a first-in-class erythrocytosis-specific treatment for PV and validate more than a decade of scientific innovation originating from Protagonist's peptide technology platform,' said Dinesh V. Patel, Ph.D., President and Chief Executive Officer at Protagonist. 'We would like to thank all the patients, study staff and investigators for participating in the VERIFY study. We are pleased to partner with Takeda as we continue to advance rusfertide to potentially transform the standard of care in PV patients around the world.' 'These promising pivotal data strongly support rusfertide's potential benefit for a broad spectrum of patients with PV who may be receiving current standard of care therapies but not achieving adequate hematocrit control,' said Phuong Khanh (P.K.) Morrow, M.D., Head of the Oncology Therapeutic Area Unit (OTAU) at Takeda. 'We look forward to receiving additional data from the VERIFY trial later this year, advancing rusfertide towards regulatory approval and continuing our collaboration with Protagonist to bring this innovative therapy to patients.' Rusfertide has received Orphan Drug designation and Fast Track designation from the U.S. Food & Drug Administration (FDA).

About VERIFY The Phase 3 VERIFY study (NCT05210790) is an ongoing, three-part, global, randomized, placebo-controlled study evaluating rusfertide in 293 patients with polycythemia vera over a 156-week period. The study is evaluating the efficacy and safety of once-weekly, subcutaneously self-administered rusfertide in patients with uncontrolled hematocrit who are phlebotomy-dependent despite current standard of care treatment, which could include hydroxyurea, interferon and/or ruxolitinib. The primary endpoint of the study was the proportion of patients achieving a response during Weeks 20-32, which was defined as the absence of 'phlebotomy eligibility.' To meet phlebotomy eligibility, patients in the study were required to have: confirmed hematocrit ≥45% that was ≥3% higher than their baseline hematocrit value, or hematocrit ≥48%. All patients have completed their participation in the randomized, placebo-controlled portion of the study evaluating the efficacy and safety of rusfertide plus current standard of care versus placebo plus current standard of care and are now in the open-label portions of the study. About Protagonist Protagonist Therapeutics is a discovery through late-stage development biopharmaceutical company.

CARMAT Announces the First Commercial Implants of Its Aeson® Artificial Heart Outside the European Union
PARIS--(BUSINESS WIRE)--Regulatory News: CARMAT (FR0010907956, ALCAR), designer and developer of the world's most advanced total artificial heart, aiming to provide a therapeutic alternative for people suffering from advanced biventricular heart failure (the ' Company ' or ' CARMAT '), today announces the first implants of its Aeson® artificial heart in a commercial set-up, outside the European Union (EU). Two implants of Aeson® artificial heart were performed during the week commencing May 26, 2025 in Israel. The first one was carried out at Hadassah Ein Kerem Hospital in Jerusalem by a team led by Pr Offer Amir, Pr Rabea Asleh and Dr Amit Korach, respectively director of the Heart Institute, director of heart failure unit and director of the cardiac surgery department at Hadassah Medical Center. The second one was carried out at Sheba Medical Center in Ramat Gan (Tel Aviv), by a team led by Dr Jeff Morgan, Dr Leonid Sternik, Dr Alex Fardman and Dr Eyal Nachum, respectively head of mechanical support unit, director of cardiac surgery department, heart failure cardiologist and cardiac transplant surgeon. Those are the first Aeson® implants made in a commercial set-up outside the European Union. These implants bring to 5 the total number of countries 1 where commercial implants have been performed so far. They confirm the trust placed in the device by healthcare professionals, and the growing interest in the therapy. About CARMAT CARMAT is a French MedTech that designs, manufactures and markets the Aeson ® artificial heart. The Company's ambition is to make Aeson ® the first alternative to a heart transplant, and thus provide a therapeutic solution to people suffering from end-stage biventricular heart failure, who are facing a well-known shortfall in available human grafts. The world's first physiological artificial heart that is highly hemocompatible, pulsatile and self-regulated, Aeson ® could save, every year, the lives of thousands of patients waiting for a heart transplant. The device offers patients quality of life and mobility thanks to its ergonomic and portable external power supply system that is continuously connected to the implanted prosthesis. Aeson ® is commercially available as a bridge to transplant in the European Union and other countries that recognize CE marking. Aeson ® is also currently being assessed within the framework of an Early Feasibility Study (EFS) in the United States. Founded in 2008, CARMAT is based in the Paris region, with its head offices located in Vélizy-Villacoublay and its production site in Bois-d'Arcy. The Company can rely on the talent and expertise of a multidisciplinary team of circa 200 highly specialized people.
