Design Therapeutics Highlights Pipeline Progress and Reports Fourth Quarter and Full Year 2022 Financial Results

Phase 1 Multiple-Ascending Dose Trial of DT-216 for Friedreich Ataxia Ongoing with Data Expected Mid-Year

Continued Progress Across Pipeline of GeneTACTM Small Molecules with Three Programs Expected to be in Clinical Development in the Next Two Years

Strong Financial Position with $330 Million in Cash and Securities Expected to Support Operating Runway through 2025

Carlsbad, Calif., March 14, 2023 – Design Therapeutics, Inc. (Nasdaq: DSGN), a clinical-stage biotechnology company developing treatments for serious degenerative genetic diseases, today highlighted recent progress and anticipated upcoming milestones across its clinical and research-stage pipeline of novel GeneTAC™ small molecules and reported fourth quarter and full year 2022 financial results.

“We are very proud of the important progress made last year with our novel GeneTAC™ small molecules, which represent a potential new class of therapies for patients suffering from devastating genetic diseases,” said João Siffert, M.D., president and chief executive officer of Design Therapeutics. “The data from the Phase 1 single-ascending dose clinical trial of DT-216 in patients with Friedreich ataxia (FA) showed, for the first time, that our GeneTAC™ small molecule DT-216 could be dosed safely and is capable of overcoming the transcription block for frataxin in individuals with FA. This underscores the potential for DT-216 to address the root cause of the disease. We’re underway with our Phase 1 multiple-ascending dose trial and look forward to evaluating the effects of three doses of DT-216 in people with FA.”

Dr. Siffert continued, “Beyond FA, we further advanced and expanded our earlier-stage pipeline, selecting DT-168 as the development candidate for our second program in FECD and progressing our DM1 program through lead optimization and advancing our discovery portfolio, with the aim of bringing two additional programs into the clinic in the next two years. With a solid cash position to support operations through a steady cadence of milestones ahead, an expert team, and diligent execution, we are well-positioned to deliver on our near- and long-term goals.”

Pipeline Progress and Anticipated Upcoming Milestones

• Data from Phase 1 Multiple-Ascending Dose (MAD) Trial of DT-216 for Friedreich Ataxia (FA) On-track for Mid-2023: Design is evaluating its lead GeneTAC™ small molecule, DT-216, in an ongoing Phase 1 MAD clinical trial designed to evaluate the safety, tolerability, pharmacokinetic, biodistribution, and pharmacodynamic effects of three weekly doses of DT-216 in adults with FA. Friedreich ataxia is a multisystem degenerative disease caused by a GAA nucleotide repeat expansion in the frataxin (FXN) gene that impairs transcription and reduces FXN mRNA. DT-216 is designed to specifically target the GAA repeat expansion mutation and restore FXN gene expression. In December 2022, Design reported initial results from its single-ascending dose (SAD) Phase 1 clinical trial in patients with FA, which showed that DT-216 was generally well-tolerated and able to overcome the FXN transcription impairment that causes FA, with a greater than two-fold increase in FXN mRNA in the cohort with the highest response. Design is advancing a Phase 1 MAD trial, with initial results

expected in mid-2023, and final data expected by year-end. A Phase 2 trial is expected to be initiated in the second half of 2023.

• IND Submission On-track for DT-168 for Fuchs Endothelial Corneal Dystrophy (FECD) in the Second Half of 2023: Design nominated its second GeneTAC™ development candidate, DT-168, an eye drop for the treatment of FECD, a genetic eye disease caused by a CTG repeat expansion in over 70% of cases. FECD is characterized by progressive degeneration of the corneal endothelium and subsequent loss of vision that affects millions of people. There is currently no effective therapeutic intervention that addresses the root causes of the disease. Design plans to submit an Investigational New Drug application (IND) for DT-168 in the second half of 2023.

• Myotonic Dystrophy Type-1 (DM1) Program Advancing toward IND in 2024: Design has continued to advance its preclinical characterization of several lead DM1 GeneTAC™ molecules for the treatments of DM1, a multi-system genetic disorder caused by a nucleotide repeat expansion in the DMPK gene that leads to progressive muscle weakness, heart disease, and gastrointestinal and endocrine dysfunctions. Progressive weakness ultimately impairs the ability to breath independently. There are currently no approved treatment options for patients with DM1. Design has demonstrated the ability of its DM1 GeneTAC™ small molecules to potently and selectively block expression of the mutant DMPK gene in DM1 patient cells. Design is working toward selection of its development candidate and anticipates submitting an IND in 2024.

Fourth Quarter and Full Year 2022 Financial Results

• R&D Expenses: Research and development (R&D) expenses were $14.3 million for the quarter ended December 31, 2022, and $48.6 million for the year ended December 31, 2022.

• G&A Expenses: General and administrative (G&A) expenses were $5.1 million for the quarter ended December 31, 2022, and $19.0 million for the year ended December 31, 2022.

• Net Loss: Net loss was $17.3 million for the quarter ended December 31, 2022, and $63.3 million for the year ended December 31, 2022.

• Cash Position: Cash, cash equivalents and marketable securities were $330.4 million as of December 31, 2022.

About Design Therapeutics

The company’s GeneTAC™ molecules are designed to either dial up or dial down the expression of a specific disease-causing gene to address the underlying cause of disease. Design is currently evaluating its lead GeneTAC™ small molecule, DT-216, in an ongoing Phase 1 clinical trial in patients with Friedreich ataxia. The company is also advancing programs in Fuchs endothelial corneal dystrophy and myotonic dystrophy type-1. Discovery efforts for multiple other serious degenerative disorders caused by nucleotide repeat expansions are also underway, including for fragile X syndrome, spinocerebellar ataxias, Huntington disease, spinobulbar muscular atrophy, and C9orf72-amyotrophic lateral sclerosis/frontotemporal dementia.
