Key Financial Metrics

Material Changes vs. Prior Period

• Operating Expenses: Total operating expenses decreased by $2.6 million (14%) for the three months ended September 30, 2024, compared to the same period in 2023. For the nine-month period, expenses decreased by $17.4 million (28%).
• Research & Development (R&D): R&D expenses decreased primarily due to the completion of clinical activities for the Friedreich ataxia (FA) program in 2023 and reduced expenses in early-stage programs. However, costs for the Fuchs endothelial corneal dystrophy (FECD) program increased as it entered clinical development.
• General & Administrative (G&A): G&A expenses decreased due to lower headcount, resulting in reduced personnel-related costs and professional fees.
• Liquidity: Cash, cash equivalents, and investment securities totaled $254.1 million as of September 30, 2024, a decrease of $27.7 million from the $281.8 million balance at December 31, 2023. Net cash used in operating activities was $33.2 million for the nine months ended September 30, 2024, compared to $45.8 million in the prior year period.

Guidance, Outlook, and Risks

• Product Pipeline Status:
  • Friedreich Ataxia (FA): The company withdrew the Investigational New Drug (IND) application for the prior DT-216 formulation in October 2023 due to injection site thrombophlebitis. A new formulation, DT-216P2, is in development. The company expects to initiate a Single Ascending Dose (SAD) Phase 1 trial of DT-216P2 in healthy volunteers in the first half of 2025, with patient dosing anticipated later in 2025.
  • Fuchs Endothelial Corneal Dystrophy (FECD): A Phase 1 clinical trial of DT-168 in healthy volunteers has been initiated and is expected to be completed by year-end 2024, with initial data expected in the first half of 2025.
  • Huntington's Disease (HD) & Myotonic Dystrophy Type 1 (DM1): Programs remain in preclinical stages.
• Liquidity Outlook: Management believes existing cash, cash equivalents, and investment securities are sufficient to fund operations for more than 12 months following the filing date. However, the company expects to incur significant losses for the foreseeable future and will require substantial additional capital to complete development and commercialization.
• Key Risks:
  • Failure to successfully develop DT-216P2 with improved tolerability or to achieve anticipated clinical timelines.
  • Dependence on third-party manufacturers and contract research organizations (CROs).
  • Competition from approved therapies (e.g., omaveloxolone for FA) and other clinical-stage programs.
  • Need to raise additional capital, which may result in dilution or unfavorable terms.

Investor Verification Checklist

• Cash Runway: Verify the sufficiency of the $254.1 million cash balance against the projected burn rate, considering the anticipated restart of FA clinical trials in 2025.
• DT-216P2 Formulation: Monitor nonclinical data and regulatory clearance for the new DT-216P2 formulation to ensure the resolution of injection site thrombophlebitis issues observed in the prior candidate.
• FECD Trial Progress: Track the completion of the DT-168 Phase 1 trial and the timing of data readouts expected in H1 2025.
• Capital Requirements: Assess the company's ability to secure future funding given the lack of revenue and the capital-intensive nature of clinical development.
• Related Party Transactions: Review ongoing lease and consulting agreements with related parties (Crossing Holdings, LLC and Marlinspike Group, LLC) for terms and expense impacts.
