Insights

Design boosts R&D and advances three clinical programs, supported by a long cash runway.

Design Therapeutics is investing heavily in its GeneTAC® pipeline. R&D expenses grew to $59.1 million in 2025, up from $44.4 million, reflecting continued progress in Friedreich ataxia, Fuchs endothelial corneal dystrophy, and myotonic dystrophy type-1 programs.

The company reported a full-year net loss of $69.8 million and ended December 31, 2025 with $219.8 million in cash, cash equivalents and investment securities. Management expects this to fund planned operations into 2029, providing a multi-year window to generate clinical proof-of-concept data across its portfolio.

Key upcoming milestones include DT-216P2 and DT-168 data in the second half of 2026 and initial DT-818 results in 2027. Subsequent disclosures around these readouts and any changes in spending levels will shape how the market assesses the platform’s potential.

Design Therapeutics Reports Fourth Quarter and Full Year 2025 Financial Results and Recent Business Updates

Trials for DT-216P2 (RESTORE-FA) and DT-168 (FECD) Ongoing; DT-818 (DM1) Dosing in Patients Expected in the First Half of 2026

Cash and Securities of $219.8 Million as of Year-End Supports Ongoing Clinical Execution

 

Carlsbad, Calif., March 9, 2026 - Design Therapeutics, Inc. (Nasdaq: DSGN), a clinical-stage biotechnology company developing treatments for serious degenerative genetic diseases, today reported fourth quarter and full year 2025 financial results and highlighted business updates and upcoming milestones across its GeneTAC® portfolio.

 

“The fourth quarter capped a year of strong execution and meaningful progress across our GeneTAC® portfolio,” said Pratik Shah, Ph.D., chairperson and chief executive officer of Design Therapeutics. “We enter 2026 with three clinical programs advancing toward important milestones, including the planned initiation of patient dosing in our Phase 1 trial of DT-818 in DM1 in the first half of the year and anticipated data from DT-216P2 in FA and DT-168 in FECD in the second half of 2026. Together, these anticipated milestones position us for continued execution of our strategy to build a diversified set of clinical proof-of-concept opportunities for genetic diseases with significant unmet needs.”

Corporate Highlights

Friedreich Ataxia (FA):

Forward-Looking Statements

Statements in this press release that are not purely historical in nature are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements include, but are not limited to: projections from early-stage programs, nonclinical data and early-stage clinical data; the progression or completion of certain development activities, including the selection of development candidates; the initiation and progression of studies and clinical trials for DT-216P2, DT-168 and DT-818 and the timing thereof; the anticipated timing for data readouts; the potential attributes and potential best-in-disease profile of DT-818; establishing clinical proof of concept for any product candidate, including the potential to have multiple programs with clinical proof-of-concept with Design’s current cash runway; Design's ability to advance the GeneTAC® platform; Design’s estimated cash runway and the sufficiency of its resources to support its planned operations; and the capabilities and potential advantages of Design’s pipeline of GeneTAC® molecules. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Words such as “believes,” “designed to,” “anticipates,” “capable of,” “plans to,” “expects,” “estimate,” “intends,” “will,” “potential” and similar expressions are intended to identify forward-looking statements. These forward-looking statements are based upon Design’s current expectations and involve assumptions that may never materialize or may prove to be incorrect. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties, which include, without limitation, risks and uncertainties associated with: the data we observe from early clinical and nonclinical studies may impact our clinical development plans; pursuing a biomarker-driven clinical development strategy carries increased risks as there are currently a limited number of approved biomarker-specific therapies; nonclinical development 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. For a more detailed discussion of these and other factors, please refer to Design’s filings with the Securities and Exchange Commission (“SEC”), including under the “Risk Factors” heading of Design’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2025, as filed with the SEC on November 5, 2025, and under the “Risk Factors” heading of Design’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, being filed with the SEC later today. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
