Agios to Highlight Pyruvate Kinase Activation Portfolio with New Data in Rare Blood Disorders at 30th EHA Congress

CAMBRIDGE, Mass., May 14, 2025 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (Nasdaq: AGIO), a leader in cellular metabolism and pyruvate kinase (PK) activation pioneering therapies for rare diseases, today announced that new data on the company’s PK activators, mitapivat and tebapivat, will be featured in oral and poster presentations during the 30th European Hematology Association (EHA) Congress (EHA 2025) in Milan, Italy, June 12-15, 2025. “The clinical results and scientific insights being presented at EHA add to the robust body of efficacy and safety data demonstrating the promise of PK activation in treating both adults and children with rare blood disorders,” said Sarah Gheuens, M.D., Ph.D., Chief Medical Officer and Head of R&D, Agios. “The presentations span serious conditions with limited or no treatment options, including sickle cell disease, thalassemia, PK deficiency, and myelodysplastic syndromes, offering meaningful results that highlight the therapeutic potential of mitapivat and tebapivat. We look forward to this important opportunity to share these new data and strengthen our collaboration with the global hematology community at EHA.” Select presentations and publications at EHA 2025 will include: An oral presentation of results from the ACTIVATE-KidsT Phase 3 study of mitapivat in children aged 1 to <18 years with PK deficiency who are regularly transfused. The study showed a clinically meaningful reduction in transfusion burden with mitapivat, with a higher proportion of patients achieving the primary endpoint of transfusion reduction response compared to placebo, though the prespecified statistical criterion was not met. Safety results were consistent with the safety profile for mitapivat previously observed in adults with PK deficiency who are regularly transfused. The ACTIVATE-KidsT study, along with the positive ACTIVATE-Kids Phase 3 trial, represents the successful execution of Agios’ first pediatric clinical program.An oral presentation of long-term data from the investigator-led ESTIMATE Phase 2 trial, an open-label study investigating mitapivat in patients with sickle cell disease. In the study, mitapivat showed sustained efficacy and tolerability over three years, including improvements in anemia, hemolysis, painful vaso-occlusive crises, and markers of kidney damage.A poster presentation with preclinical data demonstrating that tebapivat reduced red blood cell sickling and adhesion in blood samples from sickle cell disease patients, highlighting its therapeutic potential in this patient population.A preclinical publication examining expression patterns of PKM2, an isoform (or variant) of the PK enzyme. The study found that, compared with healthy controls, patients with myelodysplastic syndromes (MDS) have significantly reduced PKM2 expression in CD34+ hematopoietic stem cells, which may be implicated in the development of MDS. These findings further support the ongoing investigation of tebapivat in lower-risk MDS, as it activates PKM2 in addition to PKR (the PK isoform found in red blood cells). In total, 14 presentations and publications led by Agios and external collaborators will be shared at EHA 2025.

About PYRUKYND® (mitapivat)U.S. INDICATIONPYRUKYND is a pyruvate kinase activator indicated for the treatment of hemolytic anemia in adults with pyruvate kinase (PK) deficiency. U.S. IMPORTANT SAFETY INFORMATIONAcute Hemolysis: Acute hemolysis with subsequent anemia has been observed following abrupt interruption or discontinuation of PYRUKYND in a dose-ranging study. Avoid abruptly discontinuing PYRUKYND. Gradually taper the dose of PYRUKYND to discontinue treatment if possible. When discontinuing treatment, monitor patients for signs of acute hemolysis and anemia including jaundice, scleral icterus, dark urine, dizziness, confusion, fatigue, or shortness of breath. Hepatocellular Injury in Another Condition: In patients with another condition treated with PYRUKYND at a higher dose than that recommended for patients with PK deficiency, liver injury has been observed. These events were characterized by a time to onset within the first 6 months of treatment with peak elevations of alanine aminotransferase of >5× upper limit of normal (ULN) with or without jaundice. All patients discontinued treatment with PYRUKYND, and these events improved upon treatment discontinuation. Obtain liver tests prior to the initiation of PYRUKYND and monthly thereafter for the first 6 months and as clinically indicated. Interrupt PYRUKYND if clinically significant increases in liver tests are observed or alanine aminotransferase is >5x ULN. Discontinue PYRUKYND if hepatic injury due to PYRUKYND is suspected. Adverse Reactions: The most common adverse reactions including laboratory abnormalities (≥10%) in patients with PK deficiency were estrone decreased (males), increased urate, back pain, estradiol decreased (males), and arthralgia. Drug Interactions: Strong CYP3A Inhibitors and Inducers: Avoid concomitant use.Moderate CYP3A Inhibitors: Do not titrate PYRUKYND beyond 20 mg twice daily.Moderate CYP3A Inducers: Consider alternatives that are not moderate inducers. If there are no alternatives, adjust PYRUKYND dosage.Sensitive CYP3A, CYP2B6, CYP2C Substrates Including Hormonal Contraceptives: Avoid concomitant use with substrates that have narrow therapeutic index.UGT1A1 Substrates: Avoid concomitant use with substrates that have narrow therapeutic index.P-gp Substrates: Avoid concomitant use with substrates that have narrow therapeutic index. Hepatic Impairment: Avoid use of PYRUKYND in patients with moderate and severe hepatic impairment. Please see full Prescribing Information for PYRUKYND.
