Item 7.01			Regulation FD Disclosure

Matters Relating to PYRUKYND® in the United States

Agios Pharmaceuticals, Inc. (“Agios” or the “Company”) is aware of the securities analyst report published on August 4, 2025 (the “Analyst Report”), detailing recent PYRUKYND® data from the U.S. Food and Drug Administration’s (“FDA”) Adverse Event Reporting System (FAERS), received in connection with a Freedom of Information Act (FOIA) request.

Patient safety is of the utmost importance to Agios, and the Company maintains robust pharmacovigilance practices to collect, assess and, where appropriate, submit safety information to regulatory authorities in accordance with applicable regulations.

To date, the information available to the Company, including the cases referenced in the Analyst Report, has not altered the established benefit-risk profile of PYRUKYND, which is described in the U.S. Prescribing Information (USPI).

The Analyst Report references four patient cases. Three of the cases were reported to Agios, and subsequently reported to FDA, as part of the Company’s standard pharmacovigilance processes. Two of these cases relate to patients on commercially-available PYRUKYND, which is approved in the U.S. for the treatment of hemolytic anemia in adults with pyruvate kinase (PK) deficiency. The third case relates to a patient with sickle cell disease who received treatment with PYRUKYND through individual patient expanded access, also referred to as compassionate use, at the request of the patient’s treating physician. Under FDA regulations and guidance, FDA permits such expanded access upon a determination that, among other things, the patient to be treated has a serious or immediately life-threatening disease or condition and there is no comparable or satisfactory alternative therapy to diagnose, monitor or treat the disease or condition (“Expanded Access”).

The fourth patient case was reported directly to the FDA. Agios is evaluating this case in connection with its pharmacovigilance processes.

Based on information available at this time we understand the following regarding the cases referenced in the Analyst Report:

The first case involves a 61-year-old male receiving PYRUKYND for pyruvate kinase (PK) deficiency. No other medical history or concomitant medications were reported. Following a reported fall, an MRI revealed a shoulder mass. The patient’s relative reported he had advanced liver cancer; a healthcare professional confirmed the cause of death was metastatic cancer.

The second case involves a 93-year-old female with pyruvate kinase (PK) deficiency. No other medical history or concomitant medications were reported. A caregiver reported that the patient entered hospice due to kidney failure and cardiac issues, with minimal nutritional intake. The patient passed away while in hospice care.

The Expanded Access case involves a 26-year-old female with sickle cell disease and a pertinent medical history of heart arrhythmia, silent infarct and aneurysm. The report states that patient was receiving Procrit and Bactrim for a urinary tract infection and died from a pulmonary embolism. Transaminitis was incidentally noted in the medical record during hospitalization and was not attributed to PYRUKYND by the reporting healthcare professional.

The fourth case, which was reported directly to the FDA, involves a 28-year-old female with no medical history provided, several adverse event terms provided and Bactrim listed as another suspect drug. The adverse event terms, which include hypertransaminasaemia, lack sufficient medical context at this time. Agios is following FDA’s established process for receiving FAERS data and will evaluate any new information against the known safety profile of PYRUKYND.

Agios is committed to delivering safe, effective treatments for patients with rare diseases, and will continue to follow our established, rigorous pharmacovigilance processes.

Regulatory Update in Saudi Arabia

Separately, on August 4, 2025, the Saudi Food and Drug Authority announced that it has approved PYRUKYND for the treatment of adult patients with non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia.
