‘We are lucky and unlucky,’ SMA caregivers say of new treatments

For caregivers of children with spinal muscular atrophy (SMA), the availability of new disease-modifying treatments has offered hope — but difficulties in accessing these therapies and uncertainty about their long-term effectiveness also have fostered frustration and anxiety. That’s according to a new qualitative study, done in Canada, that aimed…

Surveys show how SMA care was aided, hindered by pandemic

The COVID-19 pandemic made it more difficult  for many people with spinal muscular atrophy (SMA) to access needed healthcare, a study highlights. At the same time, the pandemic prompted new approaches to facilitating care and running clinical trials, such as the widespread adoption of telehealth, which brings health providers…

Motor benefits of Zolgensma greater when given early: Study

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…

2nd-generation gene therapy led to better outcomes in early study

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…
