Researchers in the United States have used stem cells created from patients with a very rare type of ALS, more prevalent in Brazil, to target a key gene in the stress response and reverse the damage suffered by motor neurons in the laboratory. They believe it is "a promising proof-of-concept for future therapeutic strategies" and "could help lay the foundation for genetically informed clinical trials".
The New England Journal of Medicine reports the publication of data from a clinical trial studying the drug Tofersen against a form of Amyotrophic Lateral Sclerosis (ALS) caused by mutations in the SOD1 gene, which accounts for 2% of sporadic ALS. Six months after treatment, some biomarkers of neuronal damage improved, but not the clinical condition of the patients. In an extension of the study, with no placebo group, a slowing of functional loss was observed, although the researchers acknowledge that there are limitations in interpreting this result.
