Agios Pharmaceuticals, Inc. (NASDAQ:AGIO), a commercial-stage biopharmaceutical company focused on delivering innovative medicines for patients with rare diseases, today announced its 2026 strategic priorities and key milestones anticipated during the year. Members of the company's management team will present this update at the 44th Annual J.P. Morgan Healthcare Conference on Wednesday, January 14, 2026, at 8:15 a.m. PT / 11:15 a.m. ET.

"In 2025, Agios delivered another year of strong and consistent execution across our portfolio, marking meaningful progress toward our goal of becoming a sustainable and diversified rare disease company," said Brian Goff, Chief Executive Officer, Agios. "Last year culminated in the historic U.S. approval of AQVESME™ (mitapivat), our pyruvate kinase (PK) activator and the only medicine approved to treat anemia in adults with non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia. This approval brings a new, disease-modifying oral option to people living with this debilitating and deadly rare blood disorder.

"Entering 2026, the company is at an important inflection point. We will deliver a high-impact U.S. launch of AQVESME in thalassemia, seek to expand our PK activation franchise into additional high-value indications such as sickle cell disease and lower-risk myelodysplastic syndromes, and advance our promising early-stage pipeline with the potential to further diversify across hematologic and rare diseases. We also remain focused on disciplined capital allocation and operational efficiency to support our long-term sustainability. With strong momentum and a clear roadmap, Agios enters the year positioned to deliver transformative innovation and meaningful impact for patients living with rare diseases," Mr. Goff added.

Anticipated 2026 Milestones

Thalassemia

• In December 2025, the U.S. Food and Drug Administration (FDA) approved AQVESME for the treatment of anemia in adults with alpha- or beta-thalassemia. AQVESME is the only FDA-approved medicine for anemia in both non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia.
• Agios expects AQVESME to become available in the U.S. in late January 2026 following implementation of the AQVESME Risk Evaluation and Mitigation Strategy (REMS) program. Commercial launch activities are already underway and will continue throughout the year.

Sickle Cell Disease

• Topline results from the RISE UP Phase 3 trial of mitapivat in sickle cell disease were reported in November 2025. Agios anticipates having a pre-supplemental New Drug Application (sNDA) meeting with the FDA in the first quarter of 2026, and plans to submit a U.S. marketing application for mitapivat in sickle cell disease following that engagement.
• Enrollment in the Phase 2 sickle cell disease trial of tebapivat, Agios' more potent, once-daily oral PK activator, was initiated in 2025. Agios expects to report topline results from this trial in the second half of 2026.

Lower-Risk Myelodysplastic Syndromes (LR-MDS)

• Enrollment in the Phase 2b LR-MDS trial of tebapivat was completed in 2025. Agios expects to report topline results from this trial in the first half of 2026.
  
   

Polycythemia Vera (PV)

• Agios expects to report topline results from a Phase 1 healthy volunteer trial of AG-236, a small interfering RNA (siRNA) targeting TMPRSS6 as a potential treatment for PV, in the first half of 2026.
  
   

Phenylketonuria (PKU)

• With dosing completed in the Phase 1 single- and multiple-ascending-dose trial of AG-181, a phenylalanine hydroxylase (PAH) stabilizer, in healthy volunteers, Agios expects to initiate a Phase 1b proof-of-mechanism trial of AG-181 in patients with PKU in the first half of 2026 and to confirm proof of mechanism in the second half of 2026.
