On March 27, 2024, Ann & Robert H. Lurie Kids’s Hospital of Chicago handled its first affected person with ELEVIDYS (delandistrogene moxeparvovec-rokl), the primary gene remedy for Duchenne muscular dystrophy – a uncommon, genetic illness characterised by progressive muscle harm and weak spot. Lurie Kids’s is the primary in Illinois to manage this therapy after ELEVIDYS obtained U.S. Meals and Drug Administration (FDA) approval in June 2023.
Developed by Sarepta Therapeutics, ELEVIDYS is permitted for the therapy of Duchenne muscular dystrophy (DMD) in ambulatory sufferers aged 4 by means of 5 years with a confirmed mutation within the DMD gene.
Our crew at Lurie Kids’s has had encouraging expertise with this gene remedy for Duchenne by means of our energetic participation in medical trials. Over the previous two years, we have now handled three boys with DMD with ELEVIDYS as half of a bigger medical trial, and it is gratifying to see that their muscle power and performance stabilized. With out gene remedy, we might count on to see ongoing deterioration in muscle perform in these boys. This remedy just isn’t a treatment, and sadly it can’t reverse earlier muscle harm, however we anticipate that we will decelerate the illness sufficient for science to step in and supply new remedies. That is the start of a really thrilling journey.”

Duchenne happens in roughly one in each 3,500-5,000 new child males worldwide. It’s brought on by mutations within the dystrophin gene that result in an absence of dystrophin protein, which acts as a shock absorber when muscle tissues transfer. The primary delicate indicators of DMD could seem throughout infancy. Muscle weak spot turns into more and more noticeable between the ages of three and 5 years with the analysis being sometimes made round these ages. Most kids residing with Duchenne use a wheelchair by age 13 years. The main causes of dying in people with Duchenne are respiratory or cardiac failure, which generally happens when sufferers are of their mid-20s/30s.
Mason Flessner, now an lively 6-year-old, was one of many medical trial contributors at Lurie Kids’s who obtained ELEVIDYS about eight months in the past. He now is ready to run quicker, climb stairs extra simply and even bounce – one thing he could not do beforehand. His little brother, 3-year-old Dawson, who additionally has Duchenne, is ready till he’s sufficiently old to qualify for gene remedy.
“ELEVIDYS has been life-changing for Mason, and it has given us hope and optimism that Duchenne is now not a deadly analysis,” stated Dan Flessner, Mason’s father. “Due to analysis, gene remedy now offers us a pathway to a treatment. With a lot progress already, it is not a pipedream anymore.”
ELEVIDYS is run as a one-time intravenous infusion. The gene remedy addresses the foundation genetic reason behind Duchenne by delivering a gene that codes for a shortened type of dystrophin to muscle cells, often known as ELEVIDYS-dystrophin. As a result of dystrophin gene is the biggest identified human gene, scientists engineered a shortened model of the gene that would match inside present gene remedy supply applied sciences and nonetheless retain key purposeful data. The remedy’s accelerated approval is predicated on a rise in ELEVIDYS-dystrophin protein expression in skeletal muscle cells.
“Throughout the nation, for the reason that FDA approval, ELEVIDYS has solely been administered just a few occasions and we’re very excited to be the primary website in Illinois to manage it,” stated Abigail Schwaede, MD, one of many neuromuscular physicians on Mason’s care crew at Lurie Kids’s and Assistant Professor of Pediatrics at Northwestern College Feinberg Faculty of Medication. “This therapy has huge potential to enhance the standard of life and long-term outcomes for boys with Duchenne muscular dystrophy.”
