ARTHEx is developing an advanced RNA therapy for myotonic dystrophy type 1 (DM1) based on a portfolio of patent-protected antimiRs. These antimiRs act as long-acting disease modifiers, targeting key pathways leading to disease through a clearly defined, first-in-class mechanism of action which is unique and novel.
These molecules have shown a promising long-term therapeutic effect after one single administration (proof of concept published in and

After the optimization and selection of the lead, our project entered into the IND-enabling toxicology studies in the last quarter of 2021.We plan to move forward into the clinical phase by the beginning of 2023.
