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…
Breathing disruptions during sleep, which were prevalent in infants with spinal muscular atrophy (SMA), tended to improve on Zolgensma (onasemnogene abeparvovec) treatment without the need for additional interventions, according to a recent study. The only children who required treatment for sleep disordered breathing were those who had existing…
Researchers in Turkey have developed a new method for screening newborn blood samples for mutations associated with spinal muscular atrophy (SMA). Compared with standard techniques, the new method showed 100% accuracy for detecting SMA-positive and negative samples, they said. The scientists believe their approach, which is simpler and involves…
Children with spinal muscular atrophy (SMA) treated with Zolgensma (onasemnogene abeparvovec) used fewer healthcare resources and had lower medical costs than children on Spinraza (nusinersen), but they had higher SMA treatment costs, according to a recent U.S. analysis. Overall, healthcare costs for SMA patients using these disease-modifying…
Adults with spinal muscular atrophy (SMA) experience more health problems affecting a range of bodily systems compared with the general population, according to a U.S. healthcare claims analysis. A total of 30 conditions examined in the study, many of which are associated with older age in the general population,…
Spinraza (nusinersen) led to clinically meaningful motor improvements for three of six adults with spinal muscular atrophy (SMA) types 2 or 3 who were treated at a hospital in Japan. Other aspects, including respiratory and swallowing function, did not change considerably. “The distinct efficacy of [Spinraza] requires further…
Note: This article was updated Sept. 25 to clarify that respiratory declines were observed in patients with SMA types 2 and 3 and that the type of blood clots observed in Evrysdi-treated patients were deep vein thromboses. Evrysdi (risdiplam) safely stabilizes or improves motor function for most people…
Treatment with Spinraza (nusinersen) improved certain aspects of sleep for children with spinal muscular atrophy (SMA) type 1, according to a recent study. Patients were falling asleep sooner and spending more time asleep at night after six months of treatment. There was also evidence of alterations in electrical…
Newborn screening might not be able to detect certain rare genetic mutations that cause spinal muscular atrophy (SMA), according to a case report that recommends doctors be aware of potential false-negatives in screening and know how to spot the typical symptoms of the disease. Researchers describe the case of…
