Scholar Rock’s apitegromab led to motor function improvements over a year of treatment in young adults and children with spinal muscular atrophy (SMA) type 2 or 3 who could sit independently and were on stable standard of care, but unable to walk. That’s according to…

Nearly two-thirds of adults in South Korea with spinal muscle atrophy (SMA) type 2 or type 3 were initially misdiagnosed, according to a recent study. In type 2 cases, the primary misdiagnosis was a developmental delay, while muscular dystrophy was the main misdiagnosis in type 3…

Babies born prematurely were diagnosed with spinal muscular atrophy (SMA) through newborn screening programs (NBS) in Germany and, in most cases, started on treatment before disease symptoms emerged, a retrospective study reports. Doctors, however, waited to initiate treatment until many of the 12 newborns had reached full-term age,…

The Ministry of Health, Labour, and Welfare (MHLW) in Japan has extended the approval of Evrysdi (risdiplam) for infants genetically diagnosed with spinal muscular atrophy (SMA) who are younger than 2 months and haven’t yet had symptoms. With this extension, the treatment is now available for patients of…

Substantial differences in newborn screening (NBS) practices for spinal muscular atrophy (SMA) across the U.S. could impact referral patterns or the timing of therapeutic interventions, a study shows. While healthcare providers evaluated newborns with positive results within the first week of life, many didn’t initiate therapy until after they…

Newborn screening for spinal muscular atrophy (SMA) is now available to all babies born in Canada. The milestone announcement from Muscular Dystrophy Canada (MDC) means babies will be tested weeks after birth for SMA to allow prompt access to treatment, before symptoms appear and irreversible damage occurs, increasing…

Should results of a Phase 3 trial of apitegromab, a muscle-directed therapy for spinal muscular atrophy, be positive when released later this year as expected — supporting the add-on therapy being approved — apitegromab could be available to U.S. patients in 2025, Scholar Rock, its developer, announced.

Three years of treatment with apitegromab, a muscle-targeting therapy being developed by Scholar Rock, continues to provide clinical benefit to children and young adults with spinal muscular atrophy (SMA) type 2 or 3 who are not able to walk. That’s according to long-term results from the open-label…

Following treatment with gene therapy Zolgensma (onasemnogene abeparvovec-xioi), adding a second therapy, such as Spinraza (nusinersen) or Evrysdi (risdiplam), did not prevent widespread muscle disease progression in infants at risk of spinal muscular atrophy (SMA) type 1, a real-world study found. Although children treated with a…
