FDA Grants De Novo Clearance for Reflow Medical's Spur® Peripheral Retrievable Stent System
The Spur Stent System is the first and only retrievable stent system that features a self-expanding stent with an integrated dilatation balloon catheter on an over-the-wire system. It is designed for controlled lesion penetration and treatment through a series of radially expandable spikes. Known as Retrievable Scaffold Therapy (RST), the spikes on the Spur Stent penetrate the lesion to increase the acute luminal diameter and modify the lesion morphology to change vessel compliance and reduce vessel recoil effect.
Results of the recently concluded DEEPER REVEAL clinical trial (NCT05358353) to evaluate the Reflow Medical Spur Stent System for below-the-knee (BTK) treatment of chronic limb-threatening ischemia (CLTI), demonstrated that following predilatation, the Spur Stent System achieved a 99.2% technical success1 rate and 97.0% freedom from MALE2 and POD3 at 30 days.
"Clinical data submitted to the FDA demonstrated the safety and efficacy of the Spur Stent System," said Mahmood K. Razavi, MD, FSIR, FSVM, who serves as Director of the Clinical Trials and Research Center at St. Joseph Heart and Vascular Center in Orange, California. "This novel device will be a valuable and innovative expansion of our treatment toolbox as a unique device for the treatment of complex BTK disease," he added.
S. Jay Mathews, MD, MS, FACC, FSCAI, the Cath Lab Director at Bradenton Cardiology/Manatee Memorial Hospital in Bradenton, Florida, commented, "It's exciting to see the clinical success of the DEEPER REVEAL trial enabling the De Novo clearance of the Spur Stent System. This first-of-its-kind technology offers a truly novel approach to treating patients with BTK CLTI disease. As an adjunct to standard balloon angioplasty, Spur RST enables us to address this complex disease in a more effective way, achieving these outcomes that go beyond what PTA alone can deliver."
Both Dr. Mathews and Dr. Razavi were lead Principal Investigators for the study, which was conducted at 49 centers in the U.S. and enrolled 130 patients.
"Extensive research and development, which laid the groundwork for the DEEPER REVEAL trial, enabled the creation and clinical validation of the Spur Stent System, an innovative mechanical endovascular device engineered to enhance lesion penetration and optimize the treatment of BTK peripheral arterial disease," said Teo Jimenez, Senior Vice President of R&D at Reflow Medical.
According to Reflow Medical CEO and Co-Founder, Isa Rizk, "The FDA's De Novo clearance, following positive clinical trial results in patients with CLTI, enables us to provide physicians with an effective therapeutic option for this growing patient population. We are fully prepared to launch our innovative technology through our dedicated sales force, ensuring it promptly reaches physicians to support patients."
The FDA decision will be available on their website under DEN240048.

EMA OKs Oral Treatment for Postnatal Depression
The Committee for Medicinal Products for Human Use of the European Medicines Agency (EMA) has adopted a positive opinion on zuranolone (Zurzuvae, Biogen Netherlands BV), the first oral drug to treat postpartum depression in adults. Marketing authorization was granted in recognition of clinical trial results showing a reduction in postpartum depressive symptoms after 2 weeks' treatment. Zuranolone is a neuroactive steroid that enhances the activity of the neurotransmitter gamma-aminobutyric acid (GABA). It is thought to exert antidepressant effects by enhancing GABAergic inhibition. In a multicenter, randomized, double-blind, placebo-controlled study, zuranolone at a 50 mg dose was given for 14 days to women who met the Diagnostic and Statistical Manual of Mental Disorders criteria for a major depressive episode of postpartum depression and whose symptoms started in the third trimester or within 4 weeks of delivery. Compared with placebo, the active group demonstrated significantly greater symptom improvement on days 3,15 (the primary endpoint), and 45, using the standard 17-item Hamilton rating scale for depression. The FDA approved the drug in August 2023, at which time it was the first oral treatment for postpartum depression, with previous therapies requiring intravenous dosing. It is available in 20 mg, 25 mg, and 30 mg capsules. The most common side effects are somnolence, dizziness, confusion, trouble walking, and sedation. Patients are advised to avoid alcohol and not to drive, operate machinery, or undertake other dangerous activities until at least 12 hours after taking each dose during the 14-day treatment course. There may also be an increased risk of suicidal thoughts and actions in people 24 years of age and younger. Animal studies have suggested a possible risk of teratogenic effects, so women who may become pregnant are advised to use effective contraception during treatment and for 1 week after the final dose, and to alert their healthcare provider should they become pregnant during treatment. The EMA said that detailed recommendations will be described in the summary of product characteristics, which will be published on the EMA website in all official European Union languages after the marketing authorization has been granted by the European Commission. Perinatal Mental Healthcare 'in Its Infancy' In Western countries, postpartum depression is estimated to affect between 10% and 15% of women during the first year after birth , with substantial differences in rates depending on socioeconomic factors such as marital status, educational level, social support, spouse care, violence, gestational age, breast feeding, child mortality, financial difficulties, partnership, life stress, smoking, alcohol intake, and living conditions. Common symptoms include feelings of desperation, sadness, anxiety, irritability, and isolation, as well as nausea, changes in sleep and eating habits, decreased libido, crying spells, mental lability, thoughts of hurting oneself and/or the infant, and suicidal ideation. The condition can wreak havoc on women's mental health as well as that of their partners. It can impair the parental relationship, the mother-child bond, and the emotional and cognitive growth of infants, with potential long-term effects. Postnatal depression may occur alongside post-traumatic stress disorder following stressful or traumatic childbirth experiences . Yet a review published in Frontiers in Psychiatry last year suggested that fewer than half of countries in the World Health Organization (WHO) European region had policies specifically on perinatal mental health, leading its authors to conclude that "perinatal mental health care is in its infancy in most WHO European countries."

VCU toxicologist: ‘No vape is safe'
PORTSMOUTH, Va. (WAVY) — The trend of vaping use has picked up speed across the United States, particularly among young adults. But as cool as the smoking devices appear, Virginia Commonwealth University Forensic Toxicologist Dr. Michelle Peace says the e-cigarettes are doing more harm than good. Her candid message — no vape is safe. She has discovered in her research that 95% of all compounds in vape products are not safe to inhale. 'The framework exists for protecting the consumer,' Peace said. 'So enforcement really needs to happen full throttle. Probably just as important is education, as misinformation about vaping is rampant.' It's been her mission to expose the hidden toxic chemicals, as most users are in the dark about what they're actually inhaling. 'The primary compounds that make up a vape liquid are propylene glycol and vegetable glycerin,' she said. 'There are compounds such as ethyl acetate that are used as a flavoring chemical.' Ethyl acetate is also used in fingernail polish remover. 'So there are compounds that are used as industrial solvents to clean equipment and brakes, and the food industry uses them as a solvent for flavoring chemicals. That doesn't mean that they're safe to inhale.' So far, the has authorized 39 tobacco and menthol flavored e-cigarette products, though she says there are too many that are unregulated and without quality testing. 'We have found that the products that are authorized by the Food and Drug Administration do have significantly fewer chemicals in them,' she said, 'where, in an unauthorized product, we might find 15 to 20 different chemicals. And then, in an authorized product, we might find five or six. That's significantly less. But nonetheless, there's still chemicals that can harm people and their tissue.' Users can develop a hacking cough, dried out lung tissue or even worse. 'There are some really interesting studies that are coming out that demonstrate that vaping is changing your DNA,' she said. 'There's an indication that maybe your body is 13 years older than a non vapor. Through a project funded by the Virginia Foundation for Healthy Youth, vapes are confiscated on school campuses in the Commonwealth and sent to VCU for testing. For those indirectly inhaling vapes, there's still a second-hand risk. And the bigger issue, according to Peace, is many people are using vapes to consume other drugs. has reported more than 2,800 vaping hospitalizations nationwide. Copyright 2025 Nexstar Media, Inc.

Sarepta stock falls after Elevidys fails to get backing by EU regulators
-- Sarepta Therapeutics Inc. (NASDAQ:SRPT) stock declined 13% Friday after European regulators recommended against approving Elevidys, the company's gene therapy for Duchenne muscular dystrophy. The European Medicines Agency's drug advisory committee (CHMP) rejected Elevidys for children aged 3 to 7 years who are able to walk, the agency announced Friday. The therapy, which is marketed outside the U.S. by Roche Holding AG (SIX:ROG), was seeking approval for treating the rare genetic disease that causes progressive muscle weakness. This setback follows closely on the heels of the U.S. Food and Drug Administration's recent request for a pause on Elevidys use in the United States. Sarepta had already announced a temporary halt on U.S. shipments earlier this week. Roche has also paused shipments in jurisdictions that reference FDA approvals, further limiting the therapy's market reach. The Swiss pharmaceutical giant had been responsible for commercializing the treatment in markets outside the U.S. after partnering with Sarepta. Duchenne muscular dystrophy is a rare genetic disorder that primarily affects boys and leads to progressive muscle deterioration. The condition is ultimately fatal, with patients typically experiencing serious mobility limitations and shortened lifespans. The dual regulatory setbacks in both the U.S. and European markets represent significant challenges for Sarepta's commercialization strategy for Elevidys, which had been positioned as a breakthrough treatment option for the debilitating condition.
