Key Financial Metrics

Material Changes vs. Prior Period

• Revenue: Revenue was $0 for the three months ended September 30, 2024, compared to $353,000 in the same period in 2023. For the nine months, revenue decreased to $235,000 from $353,000. Revenue consists solely of collaboration payments from Kyorin Pharmaceutical Co., Ltd. for drug product material.
• Net Loss: Net loss increased to $17.3 million for the quarter (from $11.3 million in Q3 2023) and $49.1 million for the nine months (from $35.6 million in the prior year period).
• Operating Expenses: Total operating expenses rose to $18.1 million for the quarter and $52.3 million for the nine months.
  • R&D Expenses: Increased significantly to $14.8 million (quarter) and $42.1 million (nine months) due to the advancement of the EFZO-FIT Phase 3 study (patient enrollment) and increased manufacturing efforts for potential BLA preparation.
  • G&A Expenses: Increased to $3.3 million (quarter) and $10.2 million (nine months), driven by higher personnel costs and professional fees.
• Liquidity: Cash and cash equivalents decreased from $22.5 million at year-end 2023 to $11.5 million at September 30, 2024. Available-for-sale investments decreased from $75.6 million to $54.5 million. Total liquidity remains at approximately $68.9 million.
• Financing Activity: The company raised approximately $21.4 million in net proceeds through its "at-the-market" (ATM) offering program during the nine months ended September 30, 2024.

Guidance, Outlook, and Risks

• Clinical Outlook:
  • EFZO-FIT (Phase 3 Sarcoidosis): Enrollment of 268 patients was completed in July 2024. Topline data is anticipated in the third quarter of 2025.
  • EFZO-CONNECT (Phase 2 SSc-ILD): Interim data is expected in the second quarter of 2025. An open-label extension was added in July 2024.
• Liquidity Outlook: Management believes current cash, cash equivalents, restricted cash, and investments ($68.9 million) are sufficient to meet material cash requirements for at least one year from the filing date. The company expects to continue incurring net losses for the foreseeable future and will need to raise substantial additional capital to fund operations and commercialization.
• Subsequent Events: Between October 1, 2024, and November 5, 2024, the company sold approximately 8.1 million shares under its ATM program for net proceeds of $18.8 million, exhausting the $65.0 million capacity of the program.
• Key Risks:
  • Regulatory Uncertainty: There is no established FDA regulatory pathway for pulmonary sarcoidosis; success in the EFZO-FIT study does not guarantee approval.
  • Capital Needs: Failure to raise additional capital could force the company to delay, limit, or terminate product development.
  • Manufacturing: Reliance on third-party CDMOs and the need for comparability studies following a CDMO transition pose risks of delay.
  • Collaboration Dependence: Future revenue depends on Kyorin's performance in Japan, over which aTyr has limited control.

Investor Verification Checklist

• Cash Runway: Verify the sufficiency of the $68.9 million liquidity position against the projected burn rate, given the lack of product revenue.
• ATM Program Status: Confirm the exhaustion of the Jefferies ATM program and the company's strategy for future capital raises.
• Clinical Milestones: Monitor the timeline for EFZO-FIT topline data (Q3 2025) and EFZO-CONNECT interim data (Q2 2025) as critical value drivers.
• Manufacturing Transition: Assess the status of comparability studies required for the new CDMO to ensure no delays to the BLA submission.
• Regulatory Pathway: Review FDA communications regarding the EFZO-FIT study design and endpoints, given the lack of precedent for sarcoidosis drug approval.
