CAMBRIDGE, Mass., Jan. 08, 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 the U.S. Food and Drug Administration (FDA) accepted the company's supplemental New Drug Application (sNDA) for PYRUKYND (mitapivat) for the treatment of adult patients with non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia. The review classification for this application is Standard and the Prescription Drug User Fee Act (PDUFA) goal date is September 7, 2025.

"Thalassemia is a rare, lifelong inherited blood disorder that causes chronic anemia and can lead to severe complications, including organ damage, stroke, and other serious health issues, with patients today having limited or no effective treatment options," said Sarah Gheuens, M.D., Ph.D., chief medical officer and head of R&D at Agios. "We look forward to collaborating with the FDA in the coming months as they continue to review our application, with the goal of bringing PYRUKYND, a disease-modifying oral medication, to thalassemia patients regardless of their genotype or transfusion needs."

The sNDA is based on the results from the ENERGIZE and ENERGIZE-T Phase 3 trials evaluating mitapivat versus placebo in adults with non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia, respectively. The ENERGIZE randomized clinical trial results were presented at the European Hematology Association 2024 Hybrid Congress in June 2024, and the ENERGIZE-T randomized clinical trial results were presented at the 66th American Society of Hematology Annual Meeting and Exposition in December 2024.

About PYRUKYND (mitapivat)
U.S. INDICATION
PYRUKYND is a pyruvate kinase activator indicated for the treatment of hemolytic anemia in adults with pyruvate kinase (PK) deficiency.

U.S. 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.

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.
