R&D Highlights

• PYRUKYND (mitapivat)
  • Thalassemia –
    • Launch preparations underway ahead of U.S. PDUFA goal date of September 7, 2025. The sNDA for PYRUKYND for the treatment of adult patients with non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia remains under active review by the U.S. Food and Drug Administration (FDA).
    • Other regulatory applications remain under review by health authorities in Saudi Arabia, United Arab Emirates, and the European Union.
  • Sickle Cell Disease –
    • Topline results from RISE UP Phase 3 trial of mitapivat in sickle cell disease on track by year-end with potential U.S. commercial launch in 2026.
• Tebapivat
  • Sickle Cell Disease –
    • Dosed the first patient in the Phase 2 trial investigating tebapivat in sickle cell disease. The trial is enrolling across three dose cohorts (2.5mg, 5mg, 7.5mg) and placebo and the primary endpoint will measure hemoglobin response, defined as a ≥1g/dL increase in hemoglobin concentration from week 10 to week 12, compared to baseline.
  • Lower-risk Myelodysplastic Syndromes (LR-MDS) –
    • Continue to progress patient enrollment in the Phase 2b trial for tebapivat in LR-MDS with target enrollment completion by the end of 2025.
• Early Pipeline
  • Investigational New Drug (IND) clearance received for AG-236, an siRNA targeting TMPRSS6 intended for the treatment of polycythemia vera (PV).
• Presented new data on mitapivat and tebapivat at the 30th European Hematology Association Congress. A total of 14 presentations and publications, led by Agios and external collaborators, were shared, covering sickle cell disease, thalassemia, PK deficiency, and MDS.

Second Quarter 2025 Financial Results

For the quarter ended June 30, 2025, net loss was $112.0 million dollars, compared to a net loss of $96.1 million dollars for the second quarter ended June 30, 2024.

• Net product revenue from sales of PYRUKYND for the second quarter of 2025 was $12.5 million, compared to $8.6 million for the second quarter of 2024.
• Cost of sales for the second quarter of 2025 was $1.7 million.
• Research and Development (R&D) Expenses were $91.9 million for the second quarter of 2025, compared to $77.4 million for the second quarter of 2024. The year-over-year increase was primarily attributed to a $10.0 million regulatory milestone payment to Alnylam associated with our agreement to develop and commercialize AG-236, an siRNA targeting TMPRSS6, intended for the treatment of polycythemia vera.
• Selling, General and Administrative (SG&A) Expenses were $45.9 million for the second quarter of 2025 compared to $35.5 million for the second quarter of 2024. The year-over-year increase was primarily attributable to an increase in commercial-related activities, including headcount, as the company prepares for the potential approval of PYRUKYND in thalassemia.
• Cash, cash equivalents and marketable securities as of June 30, 2025, were $1.3 billion compared to $1.5 billion as of December 31, 2024. Agios expects that its cash, cash equivalents and marketable securities, together with anticipated product revenue and interest income, will provide the financial independence to prepare for potential PYRUKYND launches in thalassemia and sickle cell disease, advance existing programs, and opportunistically expand its pipeline through both internally and externally discovered assets.
