Design Therapeutics Announces Four-Week IV Data from the RESTORE-FA Trial of DT-216P2 Demonstrating Clinical Improvements and Comprehensive Biomarker Activity in Friedreich Ataxia

CARLSBAD, Calif., May 18, 2026 (GLOBE NEWSWIRE) -- Design Therapeutics, Inc. (Nasdaq: DSGN), a clinical-stage biotechnology company developing treatments for serious degenerative genetic diseases, today announced positive biomarker and clinical data from the ongoing Phase 1/2 RESTORE-FA trial evaluating DT-216P2 in patients with Friedreich ataxia (FA). DT-216P2 is a GeneTAC® small-molecule therapeutic candidate designed to increase frataxin (FXN) expression by targeting the GAA repeat expansion in the FXN gene, the genetic root cause of FA. 

Clinical Outcomes After four weeks of DT-216P2 treatment at the 1 mpk dose cohort, patients demonstrated mean improvements from baseline of 6.4 points in the modified Friedreich’s Ataxia Rating Scale (mFARS) and 2.7 points in the Upright Stability Score. Further, DT-216P2 demonstrated changes of greater than five points in patient-reported fatigue, as measured by the PROMIS Fatigue Scale, both at the end of four weeks of treatment and two weeks following the last dose. These data exceeded the three-point threshold generally considered to be a minimal important change in fatigue.
