How Toxic RNA Drives DM1—and Why Del-desiran Was Designed to Silence It
DM1 is driven by toxic CUG-repeat DMPK RNA that sequesters MBNL proteins and disrupts alternative splicing. This explainer examines how del-desiran was designed to correct that mechanism—and why molecular improvement did not translate into a positive Phase 3 primary endpoint.
