Friedreich Ataxia (FA) and Fuchs Endothelial Corneal Dystrophy (FECD) Programs on Track and Advancing Toward Clinical Trials Active Research Pipeline with Programs Progressing in Myotonic Dystrophy Type-1 (DM1) and Huntington’s Disease (HD) Cash and Securities of $261.0 Million Supports Operations Through Potentially Four Clinical Proof-of-Concept Data Sets CARLSBAD, Calif., Aug. 05, 2024 (GLOBE NEWSWIRE) -- Design Therapeutics, Inc. (Nasdaq: DSGN), a biotechnology company developing treatments for serious degenerative genetic diseases, today announced its second quarter 2024 financial results and reviewed upcoming program milestones for its portfolio of GeneTAC™ candidates. “In the second quarter, the company continued to make steady progress advancing our portfolio of novel, small molecule GeneTAC™ candidates for the treatment of major genetic disorders,” said Pratik Shah, Ph.D., chairperson and chief executive officer of Design Therapeutics. Dr. Shah continued, “Leading our portfolio of potential first- or best-in-class therapies is DT-216P2 for FA, a serious neuro-degenerative disease with a significant need for new therapies, and we remain on track to start patient trials in 2025. Our strategy is to address the disease’s root cause by increasing endogenous frataxin levels. In FECD, a degenerative corneal disease impacting approximately five million patients in the U.S., we are advancing DT-168 toward Phase 1 development later this year. We also continue to progress our earlier-stage programs in HD and DM1 in preparation for future development candidate nominations. Supporting our efforts is a strong cash balance that positions Design to generate clinical proof-of-concept data across our portfolio and create substantial value for patients and shareholders alike.” Corporate Highlights and Anticipated Upcoming Milestones Friedreich Ataxia (FA) Design is on track to complete GLP studies for DT-216P2 by year-end 2024 to start patient trials in 2025.Fuchs Endothelial Corneal Dystrophy (FECD) The company is on track to initiate Phase 1 development for DT-168 in normal healthy volunteers in 2024. In parallel, Design is expected to enroll 200 patients in its ongoing FECD observational study designed to confirm disease characteristics and evaluate potential endpoints and progression prior to initiating an interventional treatment trial.Pipeline programs Design also continues to advance preclinical characterization of several lead molecules toward the selection of development candidates for Huntington’s disease (HD) and myotonic dystrophy type-1 (DM1) in anticipation of future IND submissions. Second Quarter 2024 Financial Results R&D Expenses: Research and development (R&D) expenses were $10.5 million for the quarter ended June 30, 2024.G&A Expenses: General and administrative (G&A) expenses were $4.5 million for the quarter ended June 30, 2024.Net Loss: Net loss was $11.8 million for the quarter ended June 30, 2024.Cash Position and Operating Runway: Cash, cash equivalents and marketable securities were $261.0 million as of June 30, 2024, which the company expects to fund its planned operating expenses into 2029.
