A second-generation gene therapy, administered directly into the brain, led to faster and more pronounced improvements on motor function in a mouse model of spinal muscular atrophy (SMA) compared with a benchmark vector similar to the approved gene therapy Zolgensma (onasemnogene abeparvovec-xioi). That’s according to new data…

The side effects that some patients experience on Evrysdi (risdiplam), an approved treatment for spinal muscular atrophy (SMA), may be due to how the therapy alters the activity of thousands of genes when given at high doses, according to a new study in cell models. Findings also…

Treatment with Evrysdi (risdiplam) in spinal muscular atrophy (SMA) patients who previously received other therapies was found to safely stabilize motor function and lead to slight improvements in arm function, new clinical trial data show. These results occurred “irrespective of previous treatment,” the researchers wrote, adding that…

In adults with spinal muscular atrophy (SMA), treatment with Spinraza (nusinersen) in a clinical trial was tolerated well and led to improvements in arm function and self-rated health. These findings add to data from several studies that have examined the safety and efficacy of Spinraza in older…

Twin girls with type 0 spinal muscular atrophy (SMA) — the most severe form of the disease, which usually leads to death in the first months of life — are alive nearly two years after receiving early treatment with the gene therapy Zolgensma (onasemnogene abeparvovec-xioi), according to…

Children and adolescents in New Zealand with spinal muscular atrophy (SMA) will be able to access Evrysdi (risdiplan) through the country’s publicly funded healthcare system, starting in May. The decision by New Zealand’s Pharmaceutical Management Agency, known as Pharmac, means eligible patients will now have access to…

The one-time gene therapy Zolgensma (onasemnogene abeparvovec-xioi) can improve motor outcomes for children with spinal muscular atrophy (SMA) effectively, especially when it’s given in the first months of life, a review paper shows. “There is substantial evidence of improved outcomes when Zolgensma is administered early to children…

A group of proteins called the SNARE complex, which normally helps regulate how nerve cells receive chemical messages from other nerves, is disrupted in spinal muscular atrophy (SMA), according to a study with mouse models. The findings suggest a deficiency in SMN, the protein missing in SMA, may…

Children with spinal muscular atrophy (SMA) given Zolgensma (onasemnogene abeparvovec-xioi) gene therapy in clinical trials are maintaining, years later, the motor milestones they achieved in the original studies — and some have hit additional milestones even without further treatment. That’s according to data from long-term follow-up (LTFU)…

More than 1 in 4 ambulatory spinal muscular atrophy (SMA) patients experienced clinically meaningful improvements in walking ability after being treated with Spinraza (nusinersen), according to an analysis of real-world findings in Europe. “Our data demonstrate a positive effect of [Spinraza] treatment on motor function in ambulant pediatric…
