Combining 2 SMA therapies boosts SMN protein production: Study

Combining a low dose of risdiplam, the active ingredient in Evrysdi with a therapy like Spinraza (nusinersen) boosted SMN protein production beyond what the individual treatments do in cells from spinal muscular atrophy (SMA) patients, a study shows. The low-dose combination demonstrated synergistic benefits while minimizing the…

Early treatment may not resolve swallowing problems in SMA: Study

Children with spinal muscular atrophy (SMA) can still experience swallowing difficulties despite early treatment with disease-modifying therapies, a small study shows. Swallowing was either incomplete, with liquid remaining in the mouth and/or esophagus, and/or unsafe due to aspiration (the inhalation of liquid into the lungs), in all of the…

Previously unknown breathing abnormality seen in SMA type 2

A previously unknown breathing problem — called pseudo-obstructive sleep-disordered breathing — has been discovered among people with spinal muscular atrophy (SMA) type 2, a study reveals. This unusual breathing pattern during sleep is caused by an imbalance between the SMA-related weakness in the chest muscles and the relatively unaffected…

SMA newborn screening seen as cost effective in real-world terms

The start of a newborn screening (NBS) program for spinal muscular atrophy (SMA), allowing early treatment for infants found to have the disease, added to healthy years of life for patients in Belgium, according to a real-world analysis of its cost-effectiveness. “Spinal muscular atrophy newborn screening coupled with early…

Heart marker troponin-I best tested in each SMA newborn: Study

Blood levels of troponin-I, a marker for heart muscle damage, are best measured before and after gene therapy in each newborn with spinal muscular atrophy (SMA), a new study concluded. Although elevated troponin-I has been associated with SMA gene therapy, levels above the reference values generated from adults…
