ARD-1676, a medication that works by tagging toxic proteins for destruction in cells, promotes clearance of the androgen receptor (AR) protein, which is faulty and clumps in spinal and bulbar muscular atrophy (SBMA), a study found. Earlier approaches to finding a treatment for SBMA have had little success in…
For adults with spinal muscular atrophy (SMA), a genetic disease that progressively weakens breathing muscles, the approved treatment Spinraza (nusinersen) offers a crucial long-term benefit — stable lung function over several years. Data from a multi-center observational study also found that a patient’s initial breathing capacity is the…
The U.S. Food and Drug Administration (FDA) has declined to approve a higher dose of nusinersen — the medication in Biogen’s long-approved therapy Spinraza — for the treatment of spinal muscular atrophy (SMA). According to Biogen, no issues were raised with the clinical data in the company’s submission seeking regulatory…
An experimental oral combination of two therapies eased motor symptoms and prolonged survival in a mouse model of spinal muscular atrophy (SMA), a study shows. The study, “The effect of coadministration of D156844 and AR42 (REC-2282) on the survival and motor phenotype of mice with spinal muscular atrophy,”…
The use of salbutamol may safely improve upper limb strength, as well as provide other benefits, in people with spinal muscular atrophy (SMA), particularly among young children, according to data from a new meta-analysis — though the researchers noted that controlled studies are needed to confirm these findings. Two…
A quantitative MRI scan, which shows detailed images of muscles, can be used to track changes seen with Spinraza (nusinersen) treatment in children with spinal muscular atrophy (SMA), according to a new study from China. SMA children started on the approved therapy at a younger age also were found to…
Offering children with spinal muscular atrophy (SMA) type 1 the opportunity to move around on their own using motorized, ride-on cars may boost their confidence, help them connect with others, and make them feel more included, a small study found. “Powered mobility not only facilitates movement but also promotes…
After Spinraza (nusinersen) treatment for slightly longer than one year, school-aged children with spinal muscular atrophy (SMA) showed improved motor function and more independence in tasks involving their arms and hands, a study from China has found. These motor function improvements were linked to reduced symptoms of anxiety…
Gene therapy GC101 was found to rescue disease manifestations in a mouse model of spinal muscular atrophy (SMA) type 3 and to be safe in non-human primates, supporting its move into clinical testing. Genecradle Therapeutics is sponsoring ongoing Phase 1/2 clinical trials in SMA type 1 (NCT05824169),…
It can be difficult for genetic counselors in the U.S. and Canada to explain indeterminate results of prenatal screening for spinal muscular atrophy (SMA), as patients are often confused or distressed before appointments, and misunderstandings are common among both patients and doctors. Results can be indeterminate in the case…
