Add-on treatment with Scholar Rock‘s muscle-targeted therapy apitegromab continues to stabilize or improve motor function for young spinal muscular atrophy (SMA) types 2 and 3 patients who entered the study unable to walk, according to a three-year update from the TOPAZ clinical trial and its extension…

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…

The U.S. Food and Drug Administration (FDA) has given Alcyone Therapeutics the go-ahead to start a clinical trial testing ThecaFlex DRx, its implantable system for repeat use of Spinraza (nusinersen) to treat people with spinal muscular atrophy (SMA). The pivotal trial, called PIERRE (NCT05866419), will be conducted…

Researchers have developed new patient-derived cell models of spinal muscular atrophy (SMA) caused by SMN1 mutations as well as the more rare spinal muscular atrophy with respiratory distress type 1 (SMARD1). The cells exhibited structural abnormalities consistent with SMA which could be rescued with gene therapies. Scientists believe the new…

Researchers are calling for change in prenatal diagnostic procedures in Latvia after the first registered case of a newborn with spinal muscular atrophy (SMA) type 0 was reported in the country. “[It] is crucial to be able to detect this disease prenatally in order to provide the best possible…

Muscle abnormalities observed with ultrasound imaging correlated with motor function in people with spinal muscular atrophy (SMA) in a recent study. While the findings varied somewhat by muscle group and SMA type, ultrasound data generally indicated SMA patients exhibited muscle atrophy and signs of fat and connective tissue…

More than a year of treatment with Spinraza (nusinersen) did not result in clinically meaningful changes in cognition for adults with spinal muscular atrophy (SMA), according to a recent study. While patients did not exhibit widespread cognitive deficits, abnormal performance in certain domains was observed. Scores across most…

Researchers have developed a new mouse model that exhibits the features of spinal muscular atrophy (SMA) with progressive myoclonic epilepsy, or SMA-PME — a rare type of the rare disorder characterized by seizures that typically start during childhood. The mice, which exhibited motor and sensory impairments, were found to…

Scientists at The Jackson Laboratory — a U.S.-based biomedical research nonprofit — were granted $22.8 million by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health (NIH), for a novel method to develop gene editing therapies for neurological disorders, including spinal…

Current therapeutic approaches have helped to improve motor function in the majority of children with spinal muscular atrophy (SMA) type 1 in Spain, a study reports. The study, “Clinical and Functional Characteristics of a New Phenotype of SMA Type I among a National Sample of Spanish Children:…
