Most spinal muscular atrophy (SMA) patients with four or more copies of the backup SMN2 gene achieved or maintained motor milestones after treatment with Zolgensma (onasemnogene abeparvovec), according to real-world data from the RESTORE patient registry. The one-time gene therapy from Novartis was also found safe in these…

Treatment with apitegromab for two years continues to stabilize or improve measures of motor function, fatigue, and life quality in children and young adults with spinal muscular atrophy types 2 and 3 who are not able to walk. That’s according to data from the TOPAZ clinical trial…

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) studies…

Motor function is still stable or improved among people with spinal muscular atrophy (SMA) types 2 and 3 after four years of treatment with Evrysdi (risdiplam), according to updated results from the SUNFISH clinical trial. Patients and caregivers also reported continuous improvement or stabilization in the level of…

The one-time gene therapy Zolgensma (onasemnogene abeparvovec) will now be routinely accessible at low or no cost to presymptomatic infants in England who are genetically predisposed to spinal muscular atrophy (SMA). Per updated recommendations from the country’s National Institute for Health and Care Excellence (NICE), this includes…

Older children with spinal muscular atrophy (SMA) type 2 or 3, ages 2–5, given a single injection of Zolgensma into the spinal canal, showed clinically meaningful gains in motor function after one year, according to final data from the STRONG study. Such gains also were significantly better than…

High doses of Evrysdi (risdiplam), an approved daily therapy for spinal muscular atrophy (SMA), affected the development of sperm in rats and monkeys, a review of 14 preclinical safety studies reported. No damage was evident in immature sperm derived from stem cells, and changes affecting sperm ended after…

Evaluating the strength of nerve cell impulses to muscles may be a good way of predicting motor skill recovery after Zolgensma (onasemnogene abeparvovec) treatment in infants with spinal muscular atrophy (SMA), a recent study suggests. The research showed that compound muscle action potential (CMAP) amplitudes in the median…

A year of treatment with Evrysdi (risdiplam) was safe and boosted levels of SMN — the protein that’s deficient in spinal muscular atrophy (SMA) — among previously treated patients, according to published Phase 2 trial data. The safety profile was deemed similar to that observed in trials testing Evrysdi…

Children with spinal muscular atrophy (SMA) type 1 who start treatment with approved therapies after their symptoms emerge may be more likely to show below average cognitive, communication, and motor skills than those who start treatment before their symptoms, a study found. Cognitive function appeared to be most…
