Company Expects to Resume a Multiple Dose Phase 1 Clinical Study with DT-216 with an Improved Formulation in the Second Half of 2024 and Report Data in the First Half of 2025
IND Submission for FECD GeneTAC™ Program On-track for the Second Half of 2023
$303.1 Million in Cash and Securities Expected to Support Operating Runway through 2026
CARLSBAD, Calif., Aug. 14, 2023 (GLOBE NEWSWIRE) -- Design Therapeutics, Inc. (Nasdaq: DSGN), a clinical-stage biotechnology company developing treatments for serious degenerative genetic diseases, today provided business updates and anticipated upcoming milestones across its clinical and research-stage pipeline of novel GeneTAC™ small molecules and reported second quarter 2023 financial results.
“Throughout the first half of 2023, our team has been focused on executing our programs to bring our novel GeneTAC™ small molecules to patients who need them,” said João Siffert, M.D., president and chief executive officer of Design Therapeutics. “Today, we presented initial results from our Phase 1 multiple-ascending dose trial of DT-216 for the treatment of Friedreich ataxia, which show proof-of-concept for clinical activity and are in-line with our founding hypothesis that GeneTAC™ molecules are capable of restoring FXN transcription in patients with FA. Additionally, we are preparing to submit an IND later this year to enable clinical development of our novel DT-168 eye drop for patients with FECD, a degenerative genetic eye disease that affects millions of people. With an expert team and strong financial position afforded by efficient cost and program management, I am confident in our ability to execute our goals. We look forward to providing an update on our progress across our GeneTAC™ pipeline in the months to come.”
Pipeline Updates and Anticipated Upcoming Milestones
- Reported Initial Data from Ongoing Phase 1 MAD Trial Demonstrating Proof-of-Concept for DT-216 for FA: Design reported initial results, based upon a data cutoff date of August 7, 2023, from the company’s Phase 1 multiple-ascending dose (MAD) clinical trial of its lead GeneTAC™ small molecule, DT-216, in patients with FA. Exploratory analyses demonstrated that DT-216 treatment achieved a significant and dose-related increase in frataxin (FXN) mRNA levels in skeletal muscle (p < 0.05), confirming clinical activity in patients with FA in an affected tissue. DT-216 was generally well-tolerated. Injection site reactions associated with the formulation excipients, were observed across dose cohorts.
The Phase 1 findings support the continued development of DT-216 and Design plans to explore the full potential of FXN restoration with an improved formulation containing excipients with improved injection site tolerability. The company is now conducting bridging nonclinical studies to resume clinical development and expects to begin a multiple-dose Phase 1 clinical trial in the second half of 2024 with initial data expected in the first half of 2025.
- Investigational New Drug (IND) Submission On-track for DT-168 for Fuchs Endothelial Corneal Dystrophy (FECD) in the Second Half of 2023: Design is progressing its second GeneTAC™ candidate DT-168 as an eye drop treatment for patients suffering from FECD, which is caused by a CTG repeat expansion in approximately 75% 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. The company plans to submit an IND for DT-168 in the second half of 2023.
- IND Submission for Myotonic Dystrophy Type-1 (DM1) Program On-track for the Second Half of 2024: Design is advancing its preclinical characterization of several lead GeneTAC™ molecules for the treatment of DM1—a multi-system genetic disorder. Design’s DM1 GeneTAC™ small molecules potently and selectively block expression of the mutant DMPK gene in DM1 patient cells. The company is working toward selection of its development candidate and anticipates submitting an IND in the second half of 2024.
Second Quarter 2023 Financial Results
- R&D Expenses: Research and development (R&D) expenses were $17.1 million for the quarter ended June 30, 2023.
- G&A Expenses: General and administrative (G&A) expenses were $5.5 million for the quarter ended June 30, 2023.
- Net Loss: Net loss was $19.9 million for the quarter ended June 30, 2023.
- Cash Position and Operating Runway: Cash, cash equivalents and marketable securities were $303.1 million as of June 30, 2023. As a result of a strategic review of program spend and clinical prioritization, Design now expects its cash, cash equivalents and marketable securities as of June 30, 2023 to fund its planned operating expenses through 2026.
About Design Therapeutics
Design Therapeutics is a clinical-stage biotechnology company developing a new class of therapies based on its platform of GeneTAC™ gene targeted chimera small molecules. 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. In addition to its lead GeneTAC™ small molecule, DT-216, in development for patients with Friedreich ataxia, the company is 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.
