Key Financial Metrics

Material Changes vs. Prior Period

• Increased Operating Loss: Net loss for the six months ended June 30, 2024, increased by approximately $16.7 million compared to the same period in 2023, driven by higher operating expenses.
• Rising R&D Costs: R&D expenses increased by $10.4 million year-over-year (YTD), primarily due to increased external costs for pre-clinical and discovery programs (Kv7, Nav1.7, Nav1.1) and higher personnel-related costs, partially offset by reduced spend on the discontinued XEN496 program.
• Higher G&A Expenses: General and administrative expenses rose by $13.1 million YTD, attributed to increased headcount, higher stock-based compensation, and professional fees.
• Interest Income Surge: Interest income increased by $10.2 million YTD due to higher market yields and increased balances of marketable securities, partially offsetting the operating loss.
• Cash Flow: Net cash used in operating activities increased to $75.9 million (YTD 2024) from $67.6 million (YTD 2023). Net cash provided by investing activities was $64.5 million, driven by net proceeds from marketable securities.

Guidance, Outlook, and Risks

• Clinical Milestones:
  • Azetukalner (Epilepsy): Phase 3 FOS studies continue; first topline data from X-TOLE2 expected in H2 2025. Phase 3 X-ACKT trial for PGTCS is enrolling.
  • Azetukalner (MDD): First of three planned Phase 3 trials expected to initiate in H2 2024.
  • Pipeline: Company aims to file multiple INDs for next-generation ion channel modulators (Kv7, Nav1.7, Nav1.1) in 2025.
• Liquidity Outlook: Management expects existing cash and marketable securities ($850.6 million) to fund operations for at least the next 12 months. No committed external capital sources exist outside of potential collaboration milestones.
• Key Risks:
  • Continued significant operating losses and need for additional funding.
  • Dependence on the successful development and regulatory approval of azetukalner.
  • Uncertainty regarding clinical trial outcomes, patient enrollment, and regulatory timelines.
  • Reliance on third-party manufacturers and CROs.
  • Intellectual property protection challenges.

Investor Verification Checklist

• Cash Runway: Verify the sufficiency of the $850.6 million cash position against the accelerating burn rate (approx. $128M operating expenses YTD) to confirm the 12-month liquidity assertion.
• Expense Trajectory: Monitor the trend in R&D and G&A expenses, specifically the impact of stock-based compensation and headcount growth on future profitability timelines.
• Clinical Timelines: Track the initiation of the Phase 3 MDD trial (expected H2 2024) and the topline data readout for X-TOLE2 (expected H2 2025) as critical value drivers.
• Interest Income Sustainability: Assess the sensitivity of net loss to potential declines in interest rates, given the significant contribution of interest income ($22.2M YTD) to offsetting operating losses.
• Capital Raising: Review the status of the "at-the-market" (ATM) equity offering program and any potential dilutive financing needs if clinical milestones are delayed.
