Duchenne muscular dystrophy
Several companies will head to the FDA seeking approval of new Duchenne muscular dystrophy treatments next year but the death of a patient taking Sarepta’s Elevidys raises important safety questions.
WVE-N531, an oligonucleotide, elicited significant functional benefit and reversal of muscle damage in the Phase II FORWARD-53 trial. Wave plans to file for accelerated approval of the candidate in 2026.
President Donald Trump continues to warn of tariffs on the pharmaceutical industry; Susan Monarez replaces Dave Weldon as CDC director nominee; Novo Nordisk joins the triple-G race; Alnylam wins approval for Amvuttra in ATTR-CM; and Cassava Sciences ends development of simufilam in Alzheimer’s.
After Sarepta reported the death of a patient who had recently taken the gene therapy Elevidys, patient advocacy group Parent Project Muscular Dystrophy stepped up—as they always do.
Sarepta will update Elevidys’ label after a patient died following treatment; the FDA issues flu vaccine recommendations without advisor input; Trump CDC nominee Dave Weldon pulled at last minute; and FDA decisions expected for Alnylam’s Amvuttra in ATTR-CM and Milestone’s etripamil in tachycardia.
After a patient taking the Duchenne muscular dystrophy gene therapy Elevydis died of liver injury, Sarepta will update the label to reflect the safety signal.
Dyne is eyeing an accelerated approval filing for DYNE-251 in early 2026 that would pit the asset against Sarepta’s Exondys 51 in a patient population amenable to exon 51 skipping.
ITF, IntraBio and Orchard are among the companies that have won FDA nods in the past year for Duchenne muscular dystrophy, Niemann-Pick disease type C, metachromatic leukodystrophy and more.
Riding recent momentum in the Duchenne muscular dystrophy space, Capricor Therapeutics, Wave Life Sciences, Regenxbio and more aim to deliver the next wave of progress with near-term data and regulatory milestones.
While the last decade has brought considerable progress for patients with DMD, substantial unmet need remains. Several companies including Wave, Dyne and Avidity are looking to answer the call with investigational therapies targeting greater efficacy and broader reach.
