A novel monitoring tool called MScanFit may be a reliable way to assess the health of nerve and muscle cells in people with spinal muscular atrophy (SMA), a new study found. “This study demonstrated that MScanFit is feasible for the assessment of SMA patients,” the scientists wrote, noting the…

Serious side effects that can cause or prolong hospital stays occurred frequently among children with spinal muscular atrophy (SMA) who are receiving treatment with the gene therapy Zolgensma (onasemnogene abeparvovec-xioi), a new study of real-world safety data highlights. Specifically, according to the researchers, more than half of all…

Six unusual cases of children with spinal muscular atrophy (SMA) caused by sequence variants, rather than the more common genetic deletion, were described in a recent report. SMA is caused by mutations in the SMN1 gene. Everyone inherits two copies of the gene, one from each parent. SMA…

The case of a boy with spinal muscular atrophy (SMA) who had severe hyperlordosis — when the lower part of the spine curves more than is normal, forcing the belly to protrude and leading to an almost C-shaped curve over the buttocks — was described in a recent report.

Without treatment, most people with spinal muscular atrophy (SMA) who have four copies of the “backup” SMN2 gene will start developing symptoms in early childhood, a study indicates. “The early onset of symptoms in our cohort, coupled with the expected wide clinical variability, strongly supports the characterization of SMA…

In children with spinal muscular atrophy (SMA) who have a less-than-optimal response to the gene therapy Zolgensma (onasemnogene abeparvovec-xioi), subsequent treatment with Spinraza (nusinersen) can improve motor function and may reduce nerve damage. That’s according to interim data from the Phase 4 RESPOND study (NCT04488133),…

The one-time gene therapy Zolgensma (onasemnogene abeparvovec-xioi) didn’t cause any unexpected safety issues among children with spinal muscular atrophy (SMA) who weighed up to 21 kg (about 46 pounds) in a Phase 3b clinical trial, and most had stable or improved motor function a year after treatment. That’s…

Children with spinal muscular atrophy (SMA), even those with substantial physical disability, tend to report that their quality of life is similar to other children their age, a small study from Germany reports. “The results from this pilot study show that German children with SMA, despite significant physical disability,…

A Phase 1b/2a clinical trial testing the experimental therapy AJ201 in people with spinal and bulbar muscular atrophy (SBMA) has finished enrolling patients and topline data are expected in the first half of 2024. The milestone was announced by Avenue Therapeutics, which last year acquired rights to…

The gene therapy Zolgensma (onasemnogene abeparvovec) did not cause any serious long-term safety problems when used in children with type 1 spinal muscular atrophy (SMA) in a real-world study from the U.K., and most treated patients experienced improvements in motor function. “This is one of the largest studies…
