Spinraza significantly eased fatigue in adults with spinal muscular atrophy (SMA) after six months of treatment, as measured by the patient-reported Fatigue Severity Scale (FSS), a small study found. But this relief was no longer statistically significant after 10 months, its…
Identifying those spinal muscular atrophy (SMA) patients who will benefit most from treatment with Zolgensma requires more than assessing traditional SMA types, according to a consensus statement from a panel of European experts. The statement covers 11 points, and highlights that clinical trials of Zolgensma to date involved a…
The Iowa Department of Public Health has begun a pilot effort to screen newborns for spinal muscular atrophy (SMA). Babies born in Iowa are now being screened for more than 40 inherited disorders, with a goal of identifying conditions that, if caught early, can be treated or cured.
Asuragen’s diagnostic test for the analysis of genes associated with spinal muscular atrophy (SMA) — called AmplideX SMA Plus Kit — was given the European CE mark, approving it for commercial use, the company announced. The designation means the AmplideX kit complies with the European…
