Measuring the electrical activity of a pair of nerves that control arm movement, called the median nerves, could help assess how people with spinal muscular atrophy (SMA) respond to Evrysdi (risdiplam). That’s according to “Evaluation of risdiplam efficacy in 5q spinal muscular atrophy: A systematic…

Disease-modifying therapies (DMTs) may slow the progression of an abnormal curvature of the spine in people with spinal muscular atrophy (SMA) type 2, a study reported. For those patients treated early, especially ones with no or minimal scoliosis, these findings were particularly significant, according to “Early treatment of…

Adding a small molecule to a low dose of Spinraza (nusinersen) led to enhanced therapeutic benefits in a mouse model of spinal muscular atrophy (SMA), according to a recent report. The molecule, a PRMT protein inhibitor called MS023, and Spinraza — both of which are able to boost…

For a boy with spinal muscular atrophy (SMA) who was born prematurely, treatment with Spinraza (nusinersen) until he was old enough to receive Zolgensma (onasemnogene abeparvovec) was a safe and effective therapeutic approach, according to a case report from Canada. The infant, who had been diagnosed presymptomatically…

After a year of treatment with oral Evrysdi (risdiplam), 80% of babies with pre-symptomatic spinal muscular atrophy (SMA) were able to sit without support for at least five seconds. The findings met the primary outcome measure of RAINBOWFISH, a Phase 2 clinical trial (NCT03779334) evaluating the therapy…

Elevated levels of neutralizing antibodies against AAV9, which can reduce the efficacy of the gene therapy Zolgensma (onasemnogene abeparvovec), were uncommon in infants and young children with spinal muscular atrophy (SMA), a study found. It also showed that anti-AAV9 antibody levels, highest in early infancy, declined over time,…

Intellectual disability is not common among children with type 2 and 3 spinal muscular atrophy (SMA), but some aspects of cognitive function might be impaired in these children, according to a recent study. In particular, performance in specific tasks involving working memory — easily accessible information retained for a…

A novel smartphone sensor-based assessment tool is able to capture day-to-day changes in motor function in people with spinal muscular atrophy (SMA), according to a proof-of-concept study. The digital tasks are engaging and easy to complete for most SMA patients, and the results are reliable, matching those from established…

Scholar Rock announced that a Phase 3 clinical trial of its experimental muscle-targeting therapy apitegromab has finished enrolling children and young adults with spinal muscular atrophy (SMA) types 2 or 3, who are unable to walk but can sit independently. “Completing SAPPHIRE enrollment is a critical…
