Ractigen's RAG-18 Shows First Clinical Proof RNA Activation Works in DMD
Hiroshima – October 3, 2026 -- Ractigen Therapeutics presented first-in-human data showing its systemically delivered small activating RNA (saRNA), RAG-18, produced 3.5- to 5.3-fold increases in sarcolemmal utrophin expression in boys with Duchenne muscular dystrophy (DMD), marking the first clinical proof-of-mechanism for RNA activation (RNAa) in a monogenic disease. The data were disclosed in a Late-Breaking Oral Presentation at the 31st Annual Congress of the World Muscle Society (WMS 2026) in Hiroshima, Japan.
