FRIDAY, March 28, 2025 -- As a measles outbreak spreads across U.S., doctors are now seeing a new and unexpected danger: Children getting sick from taking too much vitamin A. At Covenant Children’s Hospital in Lubbock, Texas, several unvaccinated children showed signs of liver problems after taking large amounts of vitamin A, according to Dr. Lara Johnson , the hospital’s chief medical officer. U.S. Department of Health and Human Services Secretary Robert F. Kennedy Jr . has promoted vitamin A during the outbreak, even suggesting it might help prevent measles . But doctors say this isn’t true. “If people have the mistaken impression that you have an either-or choice of MMR vaccine or vitamin A, you’re going to get a lot of kids unnecessarily infected with measles. That’s a problem, especially during an epidemic,” Dr. Peter Hotez , co-director of the Texas Children’s Hospital Center for Vaccine Development and dean of the National School of Tropical Medicine at Baylor College of Medicine, told CNN . “And second, you have this unregulated medicine in terms of doses being given and potential toxicities.” The measles, mumps and rubella (MMR) vaccine is the only proven way to prevent measles. It is 97% effective after two doses. Kennedy has said he encourages vaccines, but considers vaccination a personal choice. Vitamin A can be helpful for people with measles when given in the right dose by a doctor. But taking too much, especially without medical supervision, can be dangerous. Vitamin A is fat-soluble and can build up in the body. This can lead to dry skin, blurry vision, bone problems and liver damage. In pregnant women, it can even cause birth defects. Dr. Lesley Motheral , a pediatrician in Lubbock, said kids in Texas are generally well-nourished and don’t need extra vitamin A. “Recovery for patients with acute toxicity can be rapid when the vitamin is discontinued,” Motheral said. “Sadly, some of the more serious problems with vitamin A toxicity are not always reversible.” The Council for Responsible Nutrition (CRN), a group representing supplement makers, also warned parents not to give their children high doses of vitamin A. “While vitamin A plays an important role in supporting overall immune function, research hasn’t established its effectiveness in preventing measles infection. CRN is concerned about reports of high-dose vitamin A being used inappropriately, especially in children,” it said in a statement . Johnson said some parents may be following questionable advice from social media or health influencers. “It’s coming out of the health and wellness … influencer industry that downplays the importance of vaccines and tries to promote various spectacular cures like ivermectin or hydroxychloroquine or vitamin A,” Hotez added. In a recent interview with Fox News , Kennedy promoted a treatment plan that includes vitamin A, a steroid, an antibiotic and cod liver oil, but doctors say there’s little to no proof this works for measles. The measles outbreak has now affected at least 378 people in 17 states, from Texas and New Mexico to Vermont, New York and Washington.

Following recent approvals in the EU, China and the U.S. , this approval was based on pivotal Phase 3 results in adults with elevated eosinophils Approval marks the first new treatment approach for COPD in more than a decade in Japan and the sixth approved indication for chronic diseases with underlying type 2 inflammation TARRYTOWN, N.Y. and PARIS , March 28, 2025 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today announced that the Ministry of Health, Labour and Welfare (MHLW) in Japan has granted marketing and manufacturing authorization for Dupixent® (dupilumab) for the treatment of chronic obstructive pulmonary disease (COPD) in adults whose disease is not adequately controlled with existing therapy. The approval in Japan was based on data from the landmark pivotal BOREAS Phase 3 trial. The trial evaluated Dupixent added to background maximal standard-of-care inhaled therapy (with nearly all patients on triple therapy or double therapy if inhaled corticosteroids were contraindicated) in adults with uncontrolled COPD and elevated blood eosinophils. In the trial, Dupixent significantly reduced exacerbations and improved lung function compared to placebo. Safety results in the trial were generally consistent with the known safety profile of Dupixent in its approved indications. The adverse event most commonly reported with Dupixent was injection site reaction. Results from BOREAS and the replicate NOTUS Phase 3 trial were published in The New England Journal of Medicine . In addition to COPD, Dupixent is approved in Japan in certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), prurigo nodularis and chronic spontaneous urticaria (CSU). Dupixent for the treatment of COPD has been approved in more than 45 countries worldwide, including the 27 member countries of the European Union (EU). About COPDCOPD is a chronic respiratory disease that damages the lungs and causes progressive lung function decline, and is the fourth leading cause of death worldwide. Symptoms include persistent cough, excessive mucus production and shortness of breath that may impair the ability to perform routine daily activities, which may lead to sleep disturbances, anxiety and depression. COPD is also associated with a significant health and economic burden due to recurrent acute exacerbations that require systemic corticosteroid medicine and/or antibiotics. Smoking and exposure to noxious inhaled particles are key risk factors for COPD, and even individuals who stop smoking can still have progressive lung disease. About half of COPD patients continue to experience exacerbations despite being on triple inhaled therapy. Patients with COPD and elevated eosinophils have an increased risk of exacerbations and COPD-related hospitalizations within a year. About Regeneron and Sanofi’s COPD Clinical Research ProgramRegeneron and Sanofi are motivated to transform the treatment paradigm of COPD by examining the role different types of inflammation play in the disease progression through the clinical assessment of two biologics, Dupixent and itepekimab. Dupixent is a first-in-class biologic that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways, and the program focuses on a specific population of people with evidence of type 2 inflammation. Itepekimab is a fully human monoclonal antibody that binds to and inhibits interleukin-33 (IL-33), an initiator and amplifier of broad inflammation in COPD. Itepekimab is currently under clinical investigation for COPD in two Phase 3 trials and its safety and efficacy have not been evaluated by any regulatory authority. About DupixentDupixent is available in Japan in a 300 mg dose as a pre-filled syringe or pre-filled pen and is now available for COPD. Dupixent is intended for injection under the skin (subcutaneous injection) and is given every other week. It can be given in a clinic or at home by self-administration after training by a healthcare professional. Dupixent, which was invented using Regeneron’s proprietary VelocImmune® technology, is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in Phase 3 trials, establishing that IL-4 and IL-13 are two of the key and central drivers of the type 2 inflammation that plays a major role in multiple related and often co-morbid diseases. Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, CRSwNP, eosinophilic esophagitis (EoE), prurigo nodularis, CSU and COPD in different age populations. More than 1,000,000 patients are being treated with Dupixent globally.1 About Regeneron’s VelocImmune Technology Regeneron 's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron 's co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create a substantial proportion of all original, FDA-approved fully human monoclonal antibodies. This includes Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz® (pozelimab-bbfg). In addition, REGEN-COV® (casirivimab and imdevimab) had been authorized by the FDA during the COVID-19 pandemic until 2024. Dupilumab Development Program Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical trials involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation. In addition to the currently approved indications, Regeneron and Sanofi are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes in Phase 3 trials, including chronic pruritus of unknown origin, bullous pemphigoid and lichen simplex chronicus. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority. U.S. INDICATIONS DUPIXENT is a prescription medicine used: to treat adults and children 6 months of age and older with moderate-to-severe eczema (atopic dermatitis or AD) that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies.
