Gene therapy maker Sarepta tells FDA it won't halt shipments despite patient deaths
The highly unusual move is a latest in a string of events that have hammered the company's stock for weeks and recently forced it to lay off 500 employees. The company's decision not to comply with the FDA also places future availability of its leading therapy, called Elevidys, in doubt.
The FDA said in a statement Friday night that officials met with Sarepta and requested it suspend all sales but 'the company refused to do so.' The agency has the authority to pull drugs from the market, but the cumbersome regulatory process can take months or even years. Instead, the agency usually makes an informal request and companies almost always comply.
'We believe in access to drugs for unmet medical needs but are not afraid to take immediate action when a serious safety signal emerges,' FDA Commissioner Marty Makary said in a statement.
Elevidys is the first gene therapy approved in the U.S. for Duchenne's muscular dystrophy, the fatal muscle-wasting disease that affects males, though it has faced scrutiny since its clearance in 2023. The one-time treatment received accelerated approval against the recommendations of some FDA scientists who doubted its effectiveness.
The FDA granted full approval last year and expanded the therapy's use to patients 4 years and older, including those who can no longer walk. Previously, it was only available for younger patients who were still walking.
Sarepta said Friday that its scientific review showed 'no new or changed safety signals' for younger patients with Duchenne's who have earlier stages of the disease. The company said it plans to keep the drug available for those patients.
'We look forward to continued discussions and sharing of information with FDA,' the company said in a statement.
Sarepta halted shipments last month of the therapy for older boys with Duchenne's, which gradually destroys muscle and skeletal strength, resulting in early death. The move followed the deaths of two teenage boys taking the therapy.
The company also confirmed a third death Friday: a 51-year-old patient who was taking an experimental gene therapy in a trial for a different form of muscular dystrophy. Sarepta said it reported the death to the FDA on June 20. The FDA said Friday it placed that trial on hold.
Sarepta noted that the gene therapy involved in the incident uses 'a different dose and is manufactured using a different process,' than Elevidys.
All three patient deaths were linked to liver injury, a side effect noted in Sarepta's prescribing information.
Earlier this week Sarepta announced it would add a bold warning to drug and lay off a third of its employees. The company did not mention the third patient death in its news release or conference call announcing those changes, sparking pointed criticism from Wall Street analysts.
Company shares fell more than 35% Friday to close at $14.07.
Cambridge, Massachusetts-based Sarepta has received FDA approval for three other Duchenne's drugs since 2016, none of which have been confirmed to work. The company has long been criticized for failing to complete several studies needed to secure full FDA approval of its drugs.

New Study Bolsters Public Health Case for a Four-Day Work Week
For many of us, Monday is the start of yet another dreary and long work routine. But new trial research out today might highlight a healthier approach to performing our jobs: a permanent four-day workweek. Scientists at Boston College led the study, published Monday in Nature Human Behavior. For six months, the researchers tracked the outcomes of nearly 3,000 workers at 141 businesses after they switched to a four-day workweek with no pay reduction; they also compared them to similar workers at jobs that stuck to a typical schedule. Ultimately, they found that four-day workers reported greater job satisfaction and experienced less burnout than they did before the switch, as well as when compared to people working a five-day week. These improvements were especially apparent in people who reduced their work time by eight or more hours. Gizmodo reached out to study authors Wen Fan and Juliet Schor to discuss the findings in depth, along with the implications they may hold for the future of work. Fan is an associate professor of sociology at Boston College, while Schor is an economist and sociologist at Boston College. The following conversation was lightly edited for clarity and grammar. Ed Cara, Gizmodo: The concept of a four-day workweek has gotten a lot of attention lately, from both workers and scientists. What made your team interested in studying this topic? Schor: We have long histories studying worktime and worker well-being. I wrote a book called The Overworked American many years ago but didn't get the opportunity to study worktime reductions (without pay cuts). Wen has a long history of studying many dimensions of workers' health and well-being, including stress, mental health, etc. She has also studied the impact of disruptive events on health and labor market outcomes. The pandemic was one of those and has been key to creating momentum for the four-day workweek. Fen: I just wanted to add that Juliet was incredibly generous in inviting me to collaborate on this project. Her earlier research on work hours has consistently inspired countless scholars in the field. I think the paper nicely reflects both of our research interests. It has truly been a collaborative effort between the two of us and Orla Kelly, as well as our wonderful research assistant, Guolin Gu, who has run more analyses than we can count! Gizmodo: What were the major takeaways from this latest study? Fen: There are two main findings in this study. First, we find that the four-day workweek improves workers' well-being. This conclusion comes from comparing changes in four well-being indicators between trial companies and control companies. The control companies were those that initially expressed interest in participating but ultimately did not, for various reasons. We found that employees in the trial companies experienced significant reductions in burnout, along with notable improvements in job satisfaction, mental health, and physical health. In contrast, none of these changes were observed among workers in the control companies. The second major finding is about what explains these improvements. We examined various work experiences and health behaviors. We found that three factors played particularly significant roles: work ability (a proxy for workers' self-assessed productivity), sleep problems, and fatigue. In other words, after moving to a four-day workweek, workers saw themselves as more capable, and they experienced fewer sleep problems and lower levels of fatigue, all of which contributed to improved well-being. Gizmodo: What are some of the possible implications of this work? Should more companies offer this option to their employees, for instance? Are there still important questions left to resolve about its benefits and risks, including how widely scalable it can be? Schor: There are many implications of this work—some for workers, others for the organizations and society. This is a rare kind of intervention that can make employees much better off without undermining the viability of the organizations they work for. Our research shows that both the companies and the employees benefit. (This paper is just about the employees, but we also have work showing success for employers.) So yes, we believe many more companies can offer this benefit, and they will do well with it. Their employees will be happier, more loyal, more productive, and less likely to quit. At the same time, the intervention itself is a 'forcing function' that induces improvements for the companies. There are important questions to resolve. One is how it will work at very large companies. We have organizations of up to 5,000 people that are adopting it, but we don't have a very big company in our research. We think it is scalable in that direction, however. We also would like more robust productivity and performance data from the companies. We have some metrics, but they are not complete. We don't think every company can do this right now, but many can. The more challenging ones will be places that have optimized their processes already without resulting in burned-out workers. And we think that some manufacturing companies that are highly exposed to international competition may find it challenging. However, the large majority of workers in our economy are in services/white collar, etc., which are the kinds of companies in our sample. We also think there is great scope for this in healthcare, where burnout is a serious problem. Gizmodo: Do you plan to follow up on the findings? If so, how? And what are some interesting directions that you might want other researchers to explore? Fen: Yes, we have already conducted a follow-up. While the main results in the paper are based on data collected at the six-month mark, we also continued tracking participants six months after the trial ended. We found that all major effects persisted, with well-being indicators remaining significantly higher than their baseline levels. This suggests that the benefits are not just the result of initial enthusiasm or a novelty effect but rather reflect genuine and sustainable change. There are many promising directions for future research. These include testing additional mechanisms that might underlie the well-being benefits, such as workers' perceptions of changes in organizational culture, and exploring how these interventions reshape daily work life. We also encourage researchers to take advantage of similar opportunities to conduct in-depth ethnographic research, which would allow for direct observation of organizational change as it unfolds. This line of work could inform new theories and policy interventions aimed at reimagining the structure of work, with the ultimate goal of enhancing workers' well-being while maintaining organizational performance.

The #1 Mistake People Make When Cutting Back on Calories, According to Dietitians
Reviewed by Dietitian Kelly Plowe, M.S., RDKey Points Fiber often becomes a shortfall nutrient when eating too few calories in an attempt to lose weight. Focusing on protein and eating a very low-calorie diet are reasons why we don't get enough fiber. Eating a high-fiber breakfast and a variety of foods can help you meet your daily fiber weight loss diets share a commonality: they restrict calories. After all, at the most basic level, your weight status is an equation of calories in, calories out. Research suggests that maintaining a calorie deficit (i.e., consuming fewer calories than you expend each day) is a primary factor in achieving weight loss. 'Calorie restriction can be very effective for short-term weight loss,' says weight loss dietitian Melissa Mitri, M.S., RD. However, Mitri emphasizes that other factors, like the types of food you eat, a consistent exercise routine, and effective stress management strategies, are also crucial for maintaining long-term weight loss. Effective as it may be, maintaining a calorie deficit can come with some common mistakes. The one Mitri says she sees most often: not consuming enough fiber. Neglecting this critical nutrient can do a surprising amount of harm to your weight loss efforts, not to mention derailing your digestion and downgrading your overall health. Here's why dietitians say we often fall short of fiber when on a calorie-restricted diet and how you can ensure you're getting enough. Why Fiber Falls By the Wayside When Trying to Lose Weight Fiber Isn't Exciting Let's be honest, in terms of popularity, fiber doesn't hold a candle to other, glitzier nutrients like protein or dietary supplements. 'One of the reasons people don't get enough fiber is because they simply aren't focused on it,' says weight loss dietitian Lainey Younkin, M.S., RD, LDN. 'It doesn't get as much attention as protein on social media.' Fiber's longtime association with unsexy digestive habits could be to blame for its lack of pizzazz as a weight loss aid. That said, fiber is a key nutrient for weight loss. Eating more of it is strongly associated with successful weight management, so it may be time to shift to a more balanced approach, prioritizing fiber along with other nutrients. Younkin says reading labels is a great place to start. 'Look at the dietary fiber [on Nutrition Facts labels] to see how much is in various foods that you buy.' The Focus Is On Protein It's no surprise that protein is all the rage at the moment. According to a 2025 survey by the International Food Information Council, 70% of Americans reported trying to consume more protein, a significant increase from 67% in 2023 and 59% in 2022. Additionally, high-protein diets have ranked as the most-followed eating pattern for the third consecutive year. Protein is well and good, but it's not the only superstar nutrient for weight loss. 'There is so much emphasis on protein for weight loss from the media and influencers, which leads many to believe this is the only thing that matters,' Mitri says. 'While protein is essential for health and certainly is one key nutrient for weight loss, fiber is just as essential to enhance fullness and provide volume on a reduced-calorie diet.' Not sure how much protein you need? Check out our protein calculator as a guide. Overestimating Fiber Intake If you eat a balanced diet, it's easy to believe your fiber needs are taken care of. But that's not necessarily the case. '[People often] assume that they're getting enough from eating more fruits and vegetables, and while fruits and vegetables have fiber, you have to eat a lot of them to hit your daily fiber goal of 25-38 grams per day,' Younkin says. To do so, Younkin suggests varying your plate with whole grains, beans and legumes. And if you're concerned about overdoing it on carbs, fear not! 'I often find that clients are scared of carbs, but there's no need to avoid them,' says Younkin. 'It's about choosing high-fiber carbohydrates and limiting refined carbohydrates. This will help you get more fiber, stay full longer and aid weight loss.' Eating Too Few Calories Sure, calorie restriction can be effective for weight loss, but taking it too far can mean overrestricting on fiber as well. 'A lot of my clients often think the fewer calories they eat, the better, especially if they've followed very low-calorie or overly restrictive diets in the past,' Mitri says. On an extremely calorie-controlled diet, however, it can be hard to reach the recommended amounts of fiber. Each gram of fiber contains 4 calories. At the recommended 25 grams for women and 38 grams for men, this equates to just 100 and 152 calories, respectively, from fiber each day. How to Eat Enough Fiber When Trying to Cut Calories When pursuing weight loss, stick to these dietitian-recommended strategies to keep fiber high and calories low. Prioritize protein fiber. Both of these nutrients are important for staying full. 'When planning your meals, ensure you have one to two quality sources of both protein and fiber, such as tuna or chicken for protein and leafy greens for fiber, which will help keep you full and thus make it easier to stick to a reduced-calorie diet,' Mitri advises. Keep variety in mind. You'll find fiber in all sorts of foods, so don't limit yourself to a mere handful of fruits and veggies. Whole grains, beans, nuts and seeds are other high-fiber choices. Incorporate favorite foods. If you're not enjoying your diet, you're less likely to stick with it. Mitri encourages keeping favorite foods on rotation, even when striving for a calorie deficit. Consider which high-fiber foods you genuinely like in your meals and snacks. Try a bigger, high-fiber breakfast. Younkin says the right breakfast can set you up for calorie-deficient success. 'Instead of trying to eat less, eat enough of the right nutrients to keep you full and satisfied (protein, fiber and healthy fat), so you don't raid the pantry later and end up in a calorie surplus.' Try adding high-fiber breakfast choices like oatmeal, bran cereal or a berry yogurt parfait. Our Expert Take On a low-calorie diet, fiber is your friend. While it might not seem like the most impactful nutrient, it plays a major role in promoting satiation, curbing cravings and regulating digestion—all of which factor into the success of a weight loss program. As you dial down your calories, don't fall prey to the mistake of neglecting fiber intake. High-fiber fruits, vegetables, whole grains, beans, nuts and seeds all deserve a place on a weight loss-friendly plate. Read the original article on EATINGWELL

Organ Preservation Market worth $0.3 billion by 2030 with 6.8% CAGR
DELRAY BEACH, Fla., July 21, 2025 /PRNewswire/ --The global Organ Preservation Market, valued at US$0.1 billion in 2024 stood at US$0.2 billion in 2025 and is projected to advance at a resilient CAGR of 6.8% from 2025 to 2030, culminating in a forecasted valuation of US$0.3 billion by the end of the period. The organ preservation market is experiencing robust growth fueled by rising incidence of chronic diseases, organ failure, and advancements in transplantation procedures. Increasing rates of end-stage organ conditions—such as kidney, liver, and heart failure—combined with a growing global demand for transplant procedures are key factors accelerating market expansion. The aging population, more susceptible to organ dysfunction, further highlights the increasing need for effective preservation methods to maintain organ viability pre-transplantation. Technological progress in preservation techniques, including hypothermic and normothermic perfusion, is transforming the standard of care by enhancing organ function and extending preservation times. In parallel, developing innovative preservation solutions such as the University of Wisconsin (UW) solution and Custodiol HTK significantly improves transplantation outcomes. Rising awareness among healthcare providers and the public about timely organ donation and preservation is increasing product adoption. Expanding hospital transplant programs, supportive government initiatives, and improved healthcare infrastructure in emerging markets also drive market momentum. Download PDF Brochure: Browse in-depth TOC on "Organ Preservation Market" 300 - Tables 100 - Figures 400 - Pages By solution, the organ preservation market, by solution, is categorized into UW Solution, Custodial HTK, Perfadex, and other solutions (including EuroCollins and Celsior). The UW (University of Wisconsin) solution accounted for the largest market share in 2024. This solution is widely used for preserving and flushing organs such as the liver, kidneys, and pancreas. As the first intracellular solution introduced for this purpose, it has become the benchmark in organ preservation. The dominance of the UW solution can be credited to its high efficacy in improving transplant outcomes. This is primarily due to the inclusion of metabolically inactive compounds like lactobionate and raffinose, which help reduce tissue damage, maintain cellular integrity, and enhance the physiological viability of organs during storage. These advantages have made the UW solution preferred over alternative preservation media. By technique, the static cold storage segment is expected to dominate the market due to its simplicity, cost-effectiveness, and widespread use in preserving kidneys, liver, and pancreas. While newer technologies such as hypothermic machines and normothermic perfusion are gaining traction, especially for heart and lung preservation, static cold storage remains the gold standard in many transplant centers worldwide. In addition, ongoing advancements in perfusion technologies and a growing focus on organ quality optimization before transplantation are expanding the market. The increasing initiatives by governments and non-profits to promote organ donation, along with improvements in preservation solutions and transportation logistics, are further contributing to market growth. As the demand for transplantable organs continues to outpace supply, efficient and advanced preservation methods become more crucial in ensuring transplant success. By organ type, Organ preservation, categorized by organ type, includes kidneys, liver, lungs, heart, and pancreas. In 2024, the kidney segment emerged as the leading contributor to the market. This prominence is primarily due to the rising prevalence of end-stage renal disease (ESRD), for which kidney transplantation remains the most effective treatment option. As kidney failure cases continue to grow, so does the number of transplant procedures, necessitating efficient preservation of donor kidneys before implantation in recipients. By end user, the organ preservation market is divided into transplant centers, hospitals, and specialty clinics. In 2024, the organ transplant centers segment accounted for the largest share of the market. The large share of this segment can be attributed to the extensive establishment of healthcare facilities that operate dedicated transplant programs. These centers are central to organ retrieval, preservation, and transplantation, making them critical consumers of preservation products and technologies. By geography, The Asia Pacific region is projected to grow at the highest CAGR during the forecast period. The high growth rate of the Asia Pacific region is attributed to supportive government policies, rising public awareness regarding organ donation, and a surge in organ donation activities. Countries like China and Japan have implemented standardized national guidelines for organ donation and transplantation, which are playing a key role in advancing the market. Additionally, improvements in healthcare infrastructure, the increasing burden of chronic illnesses, and the rise of medical tourism across several countries in the region are expected to fuel the market growth during the forecast period.
