First RNA therapy success: man with rare ALS improves after mutation-targeting treatment

Nature reports that a man with a rare mutation-driven form of motor neuron disease (ALS) became the first person to receive an antisense oligonucleotide therapy targeting his specific genetic mutation. A year later his symptoms improved and he continues working as a physician. Unlike conventional gene therapy, the RNA-based drug acts on the disease-causing transcript. Researchers call the early results exciting, laying groundwork for treating other rare-mutation neurodegenerative diseases.
