multiple ascending dose medical
"a Phase 1/2 multiple ascending dose study of DT-216P2 over four- or 12-week treatment periods"
A multiple ascending dose is a method used in testing new medicines where small groups of people receive gradually larger amounts of the drug over time. This approach helps researchers find the safest and most effective dose without causing too many side effects. For investors, it signals ongoing steps in drug development that can impact a company's potential success or approval prospects.

"A Phase 2 biomarker trial of DT-168 is ongoing to evaluate safety, tolerability and corneal endothelium biomarkers"
modified Friedreich Ataxia Rating Scale (mFARS) medical
"Exploratory clinical endpoints include the modified Friedreich Ataxia Rating Scale (mFARS), Upright Stability Score, and PROMIS Fatigue Scale"
A modified Friedreich Ataxia Rating Scale (mFARS) is a standardized clinical score doctors use to measure how severely a person is affected by Friedreich ataxia and how that changes over time. Think of it as a detailed scorecard or speedometer for a patient's balance, coordination and mobility used in clinical trials. Investors watch mFARS results because they serve as a measurable trial outcome that can drive regulatory decisions, signal a drug’s effectiveness, and influence a program’s commercial value.

Design Therapeutics Announces First Quarter 2026 Financial Results and Recent Business Updates

Additional Detail Provided for RESTORE-FA (DT-216P2) Trial Design, Dosing and Endpoints

 

David Shapiro, M.D., Appointed to Board of Directors, Strengthening Clinical and Regulatory Expertise

Cash and Securities of $222.8 Million at Quarter-End Provide Runway to Support Ongoing Clinical Execution

 

Carlsbad, Calif., April 28, 2026 - Design Therapeutics, Inc. (Nasdaq: DSGN), a clinical-stage biotechnology company developing treatments for serious degenerative genetic diseases, today reported first quarter 2026 financial results and highlighted business updates and upcoming milestones across its GeneTAC® portfolio.

 

“The first quarter was marked by continued operational execution across our portfolio as we progress our clinical programs, including our ongoing RESTORE-FA multiple ascending dose trial evaluating DT-216P2,” said Pratik Shah, Ph.D., chairperson and chief executive officer of Design Therapeutics. “DT-216P2 is designed to restore endogenous frataxin, with the potential to address the underlying cause of Friedreich ataxia and deliver a differentiated therapeutic approach. We believe our GeneTAC® platform represents a novel way to modulate gene expression, with the potential to unlock new therapeutic opportunities across a broad range of rare genetic diseases. We are also pleased to welcome David Shapiro, M.D., to our Board, where his experience will support the continued advancement of our clinical programs.”

Corporate Highlights

Friedreich Ataxia (FA):
o
Design continues to dose FA patients in its RESTORE-FA trial, a Phase 1/2 multiple ascending dose study of DT-216P2 over four- or 12-week treatment periods to evaluate safety, pharmacokinetics and biomarker endpoints assessing changes in endogenous frataxin (FXN) mRNA and protein levels in whole blood and muscle biopsy samples. Exploratory clinical endpoints include the modified Friedreich Ataxia Rating Scale (mFARS), Upright Stability Score, and PROMIS Fatigue Scale.
o
Design anticipates providing an update on the effect of DT-216P2 on endogenous frataxin levels in the second half of 2026.
Pipeline:
o
Fuchs Endothelial Corneal Dystrophy (FECD): A Phase 2 biomarker trial of DT-168 is ongoing to evaluate safety, tolerability and corneal endothelium biomarkers in FECD patients who are scheduled for corneal transplant surgery, with data anticipated in the second half of 2026.
o
Myotonic Dystrophy Type-1 (DM1): Design expects to begin dosing DM1 patients in its Phase 1 multiple-ascending dose (MAD) trial of DT-818, a GeneTAC® small molecule designed to selectively reduce transcription of the mutant DMPK allele, in the first half of 2026. The study, with results anticipated in 2027, is expected to assess safety and correction of mis-splicing.

 


 

o

activities and results of nonclinical studies; conducting a clinical trial and patient enrollment and retention, which are affected by many factors, and any difficulties or delays encountered with such clinical trial or patient enrollment or retention may delay or otherwise adversely affect Design’s clinical development plans; the process of discovering and developing therapies that are safe and effective for use as human therapeutics and operating as a development stage company; undesirable side effects or other undesirable properties, which could cause Design or regulatory authorities to suspend or discontinue clinical trials and thereby delay or prevent Design’s product candidates’ development or regulatory approval; Design’s ability to develop, initiate or complete nonclinical studies and clinical trials for its product candidates on the timeframe anticipated, or at all; whether promising early research or clinical trials will result in demonstrated safety and/or efficacy in later clinical trials; changes in Design’s plans to develop its product candidates; reliance on third parties to successfully conduct clinical trials and nonclinical studies; competitive products, which may make any products we develop or seek to develop obsolete or noncompetitive; Design’s reliance on third parties, including contract manufacturers and contract research organizations; Design’s ability to raise any additional funding it will need to continue to pursue its business and product development plans; regulatory developments in the United States and foreign countries; Design’s ability to obtain and maintain intellectual property protection for its product candidates; and Design’s ability to recruit and retain key scientific or management personnel.
