Brain fluid biomarkers may help distinguish SMA types, study finds

Levels of certain molecules in cerebrospinal fluid (CSF) — the liquid that surrounds the brain and spinal cord — may help researchers distinguish between different types of spinal muscular atrophy (SMA), a study suggests. The study, “Metabolomics of cerebrospinal fluid reveals candidate diagnostic biomarkers to distinguish…

Study examines side effects observed with SMA gene therapy

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…

MDA 2024: Spinraza may benefit some SMA children after Zolgensma

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),…

MDA 2024: Zolgensma gene therapy safe in children up to 21 kg

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 SMA express good quality of life in small study

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,…
