CAMBRIDGE, Mass., Nov. 05, 2024 (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 mitapivat and tebapivat (AG-946), the company’s PK activators, will be featured in oral and poster presentations during the 66^th American Society of Hematology (ASH) Annual Meeting and Exposition in San Diego, California from December 7-10, 2024.

“These data we are presenting at ASH reaffirm our confidence in our growing pipeline focused on improving red blood cell health,” Sarah Gheuens, M.D., Ph.D., chief medical officer and head of R&D at Agios. “We will highlight the clinical progress of our two PK activators – mitapivat and tebapivat – in multiple rare blood disorders with high patient needs, including thalassemia, sickle cell disease and myelodysplastic syndromes. These advancements showcase the quality of science and potential novel solutions coming out of our research and development efforts.”

Key presentations and publications at ASH 2024 will include:

• An oral presentation on results from the Phase 3 ENERGIZE-T study evaluating mitapivat in adults with transfusion-dependent alpha- or beta-thalassemia versus placebo. Alongside the positive results from the Phase 3 ENERGIZE study of mitapivat in non-transfusion-dependent alpha- or beta-thalassemia previously presented at the 2024 European Hematology Association (EHA) Congress, these data support mitapivat’s potential as an oral, disease-modifying therapy across the full range of patients with thalassemia regardless of transfusion status.
  
• A poster presentation of a Phase 1 study assessing the safety, tolerability, pharmacokinetics and pharmacodynamics of tebapivat in patients with sickle cell disease, providing further evidence that PK activation may have beneficial effects in this patient population.
  
• A trial-in-progress publication that outlines the Phase 2b study evaluating the efficacy and safety of tebapivat in patients with anemia due to lower-risk myelodysplastic syndromes.
  

In total, 16 presentations and publications led by Agios and external collaborators will be shared at ASH 2024.

About PYRUKYND^® (mitapivat)
PYRUKYND is a pyruvate kinase activator indicated for the treatment of hemolytic anemia in adults with pyruvate kinase (PK) deficiency in the United States, and for the treatment of PK deficiency in adult patients in the European Union.

IMPORTANT SAFETY INFORMATION
Acute 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.

Adverse Reactions: Serious adverse reactions occurred in 10% of patients receiving PYRUKYND in the ACTIVATE trial, including atrial fibrillation, gastroenteritis, rib fracture, and musculoskeletal pain, each of which occurred in 1 patient. In the ACTIVATE trial, 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.
