Design Therapeutics announced the initiation of patient dosing in its Phase 1 multiple-ascending dose clinical trial evaluating DT-818 in adults with myotonic dystrophy type-1. DT-818 is a GeneTAC small molecule designed to selectively reduce transcription of the mutant DMPK allele and address the underlying cause of DM1. The Phase 1 trial is an open-label, MAD study designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamic effects of DT-818 in adults with DM1. Design anticipates reporting data from this study in 2027.

About DSGN
Design Therapeutics, Inc. is a biotechnology company. It is engaged in the research and development of GeneTACT molecules, which are small-molecule gene targeted chimera therapeutic candidates designed to be disease-modifying by addressing the underlying cause of diseases caused by inherited nucleotide repeat expansion mutations. Its Friedreich ataxia (FA) program is focused on the development of a disease-modifying treatment. Its DT-216 is developed to overcome the FXN transcription impairment that causes FA. DT-216 is in Phase I clinical trial. It is also engaged in developing DT-216 to enable higher exposure and chronic administration for treatment of FA, known as DT-216P2, which uses the same drug substance, DT-216. Its FECD program is focused on the development of a potentially disease-modifying medical treatment for FECD, DT-168, which is in Phase I clinical trial. Its Huntington's Disease program is focused on the development of a potentially disease-modifying treatment for HD.

RESTORE-FA Trial Progressing Well with Promising Data Expected
- Trial Progress: The RESTORE-FA trial is progressing well, with data expected in the second half of 2026, aiming to provide a go/no-go decision for the FA program and establish clinical proof of concept to inform future regulatory pathways.
- Biomarker Evaluation: The study is evaluating endogenous frataxin levels in both blood and muscle, focusing on mRNA and protein to identify a potential primary surrogate biomarker that could reasonably predict clinical benefit.
- Mechanism of DT216: DT216 is a heterobifunctional gene-targeted chimera designed to recognize long GA repeat expansions and increase normal frataxin RNA transcription, with cellular data suggesting that 10 nanomolar levels may be sufficient to increase frataxin with adequate exposure duration.
- Dosing Structure: The dosing structure of the RESTORE-FA study began with escalations from 0.1 mg/kg to 0.6 mg/kg over four weeks, and a 1 mg/kg group has been initiated, incorporating 12-week treatment cohorts to generate additional exposure and data.
