Shockwave Medical Study Confirms Benefit of IVL-First Strategy in Real-World Female Patients with Complex Calcified Lesions in Late-Breaking Data Presentation at EuroPCR 2025
EMPOWER CAD, a global prospective, multi-center, real-world study, reaffirms favorable acute outcomes for coronary IVL in female patients, unlike other calcium modification tools
PARIS, May 20, 2025 /PRNewswire/ -- Shockwave Medical, Inc., part of Johnson & Johnson MedTech and a global leader in the field of circulatory restoration, announced today the 30-day primary endpoint results of EMPOWER CAD, the first prospective, real-world percutaneous coronary intervention (PCI) study in female patients with complex, calcified coronary artery disease. The favorable results confirm the results of earlier retrospective analyses demonstrating the benefits of coronary intravascular lithotripsy (IVL) in female patients. The results were presented in a late-breaking presentation at the annual EuroPCR meeting in Paris.
Women with coronary artery calcification (CAC) undergoing PCI are often underrepresented in clinical trials and have historically poorer outcomes than men, including increased risk of adverse clinical outcomes and high rates of procedural complications with other calcium modification treatments, such as rotational or orbital atherectomy.1,2
Investigators designed the EMPOWER CAD study to evaluate real-world outcomes in female patients with severely calcified coronary lesions treated with an IVL-first treatment strategy and confirm positive results from previous studies showing similar safety and effectiveness outcomes across both men and women. EMPOWER CAD is a pivotal study comprised of a series of firsts: Shockwave's first prospective, post-market study of IVL examining an all-comers female population with minimal exclusion criteria, the first study to encourage a Shockwave IVL-first PCI strategy for calcified coronary lesions, and the first study to follow-up with enrolled patients for three years following IVL therapy.
The study enrolled 399 participants across 45 sites spanning five countries in the European Union and United States. The study is led by co-principal investigators Margaret McEntegart, M.D., Ph.D., Director of the Complex PCI and CTO programs and Cardiac Catheterization Labs at Columbia University Medical Center/NewYork-Presbyterian Hospital and Alexandra Lansky, M.D., Professor of Medicine in the section of Cardiovascular Medicine and Director, Heart and Vascular Clinical Research Program, Yale University School of Medicine. The study's European lead is Nieves Gonzalo, M.D., Ph.D., consultant interventional cardiologist at Hospital Clinico San Carlos in Madrid, Spain.†
"Women are typically underdiagnosed, underrepresented and have underwhelming outcomes in coronary artery disease studies," said Dr. Lansky. "Our goal with the EMPOWER CAD study was to address this gap and determine whether Shockwave IVL should be considered as the front-line calcium modification approach in female patients with complex coronary artery disease. The results demonstrate the benefits of IVL use in this specific patient population and validate findings from previous studies."
The primary effectiveness endpoint of procedural success, defined as stent delivery with ≤30% residual stenosis for all treated target lesions without in-hospital target lesion failure (TLF), was 86.9% at 30 days. The primary safety endpoint, defined as TLF as a composite of cardiac death, myocardial infarction attributable to target vessel (TV-MI) or ischemia-driven target lesion revascularization (ID-TLR) within 30 days, was 12.1%. TLF was primary driven by the rate of periprocedural MI3 (10.6%); the majority of these periprocedural MIs were not associated with any clinical signs or symptoms. Cardiac death and ID-TLR rates were each 1.3%. Procedural complications were rare with only one patient (0.2%) having a serious angiographic complication when assessed at the end of the procedure. There were also clinically and statistically significant improvements in health-related quality of life scores at 30 days compared to baselines.
"By leveraging a Shockwave IVL-first approach, the EMPOWER CAD 30-day results demonstrated high procedural success, low complication rates and significant improvements in quality of life among real-world female patients," said Dr. McEntegart. "While we look forward to following these patients for the next three years, these primary endpoint results confirm that excellent outcomes can be achieved with the use of Shockwave IVL in women with complex, calcified coronary artery disease."
Nick West., M.D., Chief Medical Officer, Shockwave Medical, emphasized the significance of the EMPOWER CAD study, stating, "Today marks a critical milestone in the journey to improve outcomes for female patients with calcified lesions. What began as an idea a few years ago is now a commendable reality today, thanks to study leadership and site investigators accelerating completion and reporting these important results. We're looking forward to learning more about the benefits of IVL therapy in this underrepresented patient population, both acutely and at extended follow-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.

Northern lights could be visible tonight if hazy skies clear up
COLUMBUS (WCMH) — A powerful solar eruption from the sun's surface early on June 1 sent charged particles streaming toward Earth at more than four million miles per hour, which could provide a view of the northern lights across portions of the United States and Canada Sunday night, and possibly Monday night. The geomagnetic storm reached the level of G4 Sunday morning on a scale of 1 (minor) to 5 (extreme), which brings a higher likelihood of seeing the northern lights farther south than usual, in places such as northern California, Illinois, and the northern Mid-Atlantic region. The best time to look for the shimmering display of color is between 10 p.m. and 2 a.m. near the northern horizon if you reside in a more rural area with darker skies away from city lights. However, smoke from Canadian wildfires may preclude the view in some areas of the country. A coronal mass ejection (CME) sends electrically charged particles (ions) and magnetic material streaming into space, generating currents in the magnetic field. When the solar wind collides with Earth's magnetic field (magnetosphere), the interaction with gases (oxygen, nitrogen) in the upper atmosphere produces streaks or curtains of light, known as the aurora borealis in the Northern Hemisphere. The most common color arising from collisions between solar particles (atoms) and oxygen molecules is green, because the red veils occur higher up in the atmosphere and are harder to view. Nitrogen interactions at lower altitudes trigger blue curtains of light. Last year on May 10, a G4 storm triggered spectacular views of the northern lights in parts of central Ohio. Another view of the northern lights occurred on Oct. 10, 2024, but was much more limited in our area. Severe geomagnetic storms can affect high-frequency communications, disrupting GPS systems and low-frequency satellite navigation signals. In extreme events, the CME voltage can impact the electric energy or power grid, resulting in regional blackouts. Copyright 2025 Nexstar Media, Inc. All rights reserved.

Avera honors hundreds of cancer survivors
SIOUX FALLS, S.D. (KELO) — It's National Cancer Survivors Day, and to celebrate, Avera spent the day honoring patients who beat the odds. Biking 4,000 miles to help homeless veterans Hundreds of cancer survivors came out the the Prairie Center in Sioux Falls where they enjoyed a free meal and a superhero theme. It's the 15th time Avera has hosted the event. Survivors say it was helpful for them to be around people who know exactly what they went through. 'The thought of being with other survivors because sometimes it kind of feel like you're alone in this whole journey. Just to see that other people that have survived, too, is going to be kind of cool,' cancer survivor Terri Vanden Bosch said. 'Their lives are essentially flipped upside down, and unless we've been in those shoes, we just honestly don't necessarily understand that,' Avera certified nurse practitioner Jennifer Reiner said. The survivors also got to add their names to a survivor tree painting and listen to guest speakers. The new Miss South Dakota has been crowned Copyright 2025 Nexstar Media, Inc. All rights reserved.
