Basel, July 2, 2026 – Novartis today announced that the European Commission (EC) has approved Itvisma® (onasemnogene abeparvovec) for the treatment of children two years and older, teens and adults living with 5q spinal muscular atrophy (SMA) with a bi-allelic mutation in the survival motor neuron 1 ( SMN1 ) gene. With this approval, Itvisma becomes the first and only gene replacement therapy currently approved for this broad SMA population in the European Union. Itvisma is uniquely designed to address the genetic root cause of SMA with a one-time fixed dose that does not need to be adjusted for age or body weight.1 By replacing the SMN1 gene, Itvisma can improve motor function, offering a one-time treatment option distinct from ongoing dosing approaches associated with other available therapies for this population.1 "European approval is an important milestone for the SMA community. Beyond the scientific achievement, it brings the prospect of a new treatment option closer to people and families who are looking for choices that reflect their individual needs and circumstances. We welcome today's decision and hope it translates into timely and equitable access across Europe," said Nicole Gusset, CEO of SMA Europe. "Maintaining or improving motor function can make a meaningful difference for older children, teens and adults living with SMA," said Professor Jana Haberlová, Head of Neuromuscular Centre at the Department of Paediatric Neurology, Motol and Homolka University Hospital, Prague, Czech Republic. "The approval of Itvisma in Europe is an important advance because it brings a new gene replacement therapy option to a broader patient population and gives clinicians an additional way to support patients across the course of the disease." The approval is based on data from the registrational STEER study, and supportive Phase IIIb STRENGTH and Phase I/II STRONG studies.1,2,3 In STEER, Itvisma demonstrated a statistically significant 2.39-point improvement in the Hammersmith Functional Motor Scale (HFMSE) with effects sustained over 52 weeks of follow-up.1 The STEER and STRENGTH studies also showed clinically meaningful benefit for treatment-naïve and pre-treated patients.1,2
