Adults with spinal muscular atrophy (SMA) who start treatment with Spinraza (nusinersen) tend to see the most dramatic early improvement in muscle strength in the shoulders and upper arms, a new study suggests. The treatment also tended to improve thumb strength, which researchers note may be important for…

Spinraza (nusinersen) carries relatively few side effects and nearly halves the odds of children and adolescents with spinal muscular atrophy (SMA) having serious or fatal side effects compared with a placebo, according to a meta-analysis. The study, “Adverse events in the treatment of spinal muscular atrophy in…

The adoption of a newborn screening (NBS) program for spinal muscular atrophy (SMA) in England would reduce healthcare costs and boost the number of healthy years a patient can live, according to a recent cost-effectiveness analysis. Researchers believe such a program could capture most cases of SMA in the…

The overactivity of a specific signaling pathway may contribute to the abnormalities in clearing cellular waste that are commonly seen in spinal muscular atrophy (SMA), according to experiments with patient-derived cells. This known cell survival pathway, dubbed the ERK signaling pathway, exhibited increased activity in the cells, while its…

The Muscular Dystrophy Association (MDA) has opened the MDA Gene Therapy Support Network — a new program it’s dubbed GTx — to aid and educate families living with spinal muscular atrophy (SMA) or other neuromuscular diseases (NMDs) who may be considering a gene therapy as part of…

Children with spinal muscular atrophy (SMA) who are treated with Zolgensma (onasemnogene abeparvovec-xioi) tend to have more dramatic gains in motor function when it’s given earlier in the course of disease, a new study reports. The findings suggest the best improvements are seen among babies treated in the…

Alterations to the composition of intestinal microbes — called the gut microbiome — in spinal muscular atrophy (SMA) patients may contribute to certain metabolic disorders that are commonly seen in patients, according to a recent study. Scientists identified a number of altered gut bacteria in children with SMA relative…

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 announced…

In real-world settings, the one-time gene therapy Zolgensma (onasemnogene abeparvovec-xioi) is well tolerated and improves motor function outcomes in children with spinal muscular atrophy (SMA) — especially when given at ages younger than 8 months — a study in Israel found. Treatment with Zolgensma also was found to…

Boosting the production of the growth factor protein NRG1-III improved motor nerve fiber development in the early stages in a mouse model of spinal muscular atrophy (SMA), a study showed. NRG1-III was unable to prevent nerve fibers from degenerating or improve motor function or survival in older mice, however.
