High doses of Evrysdi (risdiplam), an approved daily therapy for spinal muscular atrophy (SMA), affected the development of sperm in rats and monkeys, a review of 14 preclinical safety studies reported. No damage was evident in immature sperm derived from stem cells, and changes affecting sperm ended after…

Evaluating the strength of nerve cell impulses to muscles may be a good way of predicting motor skill recovery after Zolgensma (onasemnogene abeparvovec) treatment in infants with spinal muscular atrophy (SMA), a recent study suggests. The research showed that compound muscle action potential (CMAP) amplitudes in the median…
A year of treatment with Evrysdi (risdiplam) was safe and boosted levels of SMN — the protein that’s deficient in spinal muscular atrophy (SMA) — among previously treated patients, according to published Phase 2 trial data. The safety profile was deemed similar to that observed in trials testing Evrysdi…
Children with spinal muscular atrophy (SMA) type 1 who start treatment with approved therapies after their symptoms emerge may be more likely to show below average cognitive, communication, and motor skills than those who start treatment before their symptoms, a study found. Cognitive function appeared to be most…
Avenue Therapeutics has won the exclusive rights to develop and commercialize AJ201, AnnJi Pharmaceutical’s experimental treatment for spinal and bulbar muscular atrophy (SBMA), in certain regions of the globe under the terms of a new licensing agreement. Specifically, the agreement lists the U.S., Canada, the European Union,…
TREAT-NMD and Aetion have formed a partnership to deliver real-world evidence and promote the development of new treatments for people with rare neuromuscular diseases, including spinal muscular atrophy (SMA). The projects will combine the expertise of the TREAT-NMD global registry network, which collects de-identified data from patients…
More than 1 in 4 ambulatory spinal muscular atrophy (SMA) patients experienced clinically meaningful improvements in walking ability after being treated with Spinraza (nusinersen), according to an analysis of real-world findings in Europe. “Our data demonstrate a positive effect of [Spinraza] treatment on motor function in ambulant pediatric and…
A 23-day-old girl with spinal muscular atrophy (SMA) type 2, later treated with Spinraza (nusinersen), underwent successful surgical repair of heart defects, according to a new case report. The researchers noted that individuals with SMA may be perceived as risky surgical candidates, considering the poor prognosis for untreated…
The U.S. Food and Drug Administration (FDA) has given fast track designation to Biohaven Pharmaceuticals‘ experimental medicine taldefgrobep alfa for the treatment of spinal muscular atrophy (SMA). The designation is granted to therapies that show potential in addressing serious conditions for which available treatments fall short. It is…
Treatment with bicalutamide and trehalose extended survival and improved motor function in a mouse model of spinal and bulbar muscular atrophy (SBMA), a study has found. Both compounds had beneficial effects on some aspects of muscle fiber structure and reduced cell death. While bicalutamide also lowered levels of toxic…
