ASO Therapy

ASO stands for antisense oligonucleotide. An ASO is a short, designed strand of nucleic acid that binds to a specific RNA message inside the body. Depending on how it is designed, an ASO may reduce a harmful RNA, change splicing, increase production from a working gene copy, or alter how a protein is made. ASOs are not the same as gene therapy: they usually act at the RNA level and often require repeat dosing.

Why it matters

ASOs are one of the most important platforms in rare disease medicine because they can sometimes be designed for very specific genetic mechanisms, including disorders that may not be a good fit for classic gene replacement.
