ASO-tagged siRNA can enter the human CNS and may improve SOD1 lowering in ALS patients.
- Why it matters: Effective delivery of siRNA to the CNS remains a challenge in treating neurodegenerative diseases like ALS. Improving this delivery could enhance therapeutic outcomes.
- What they did: Chen et al. conducted a first-in-human study using an antisense oligonucleotide (ASO) tag to deliver SOD1 siRNA to the CNS in ALS patients, aiming for better targeting.
- The result: The approach potentially enables faster, more extensive, and better-tolerated SOD1 reduction, which could advance ALS treatment strategies.
