Agios Pharmaceuticals presented detailed results from the 52-week double-blind period of the global RISE UP Phase 3 trial of mitapivat. These efficacy and safety results, which include new transfusion burden and hemoglobin responder analyses reinforcing the strong anti-hemolytic profile of mitapivat, were presented during the distinguished Plenary Abstracts Session at the 31st European Hematology Association, EHA, Congress in Stockholm, Sweden. Key highlights: Mitapivat demonstrated statistically significant improvement in hemoglobin response compared with placebo, with rapid onset and durable effects; New analyses showed patients in mitapivat arm had clinically meaningful reduction in transfusion burden compared with placebo; Patients in mitapivat arm who achieved hemoglobin response had clinically meaningful benefits across measures of sickle cell pain crises, fatigue, and other patient-reported outcomes; Mitapivat was well-tolerated, with a safety profile consistent with previous trials of mitapivat in sickle cell disease

About AGIO
Agios Pharmaceuticals, Inc. is a biopharmaceutical company. The Company is focused on developing and delivering transformative therapies for patients living with rare diseases. It markets a first-in-class pyruvate kinase (PK) activator for adults with PK deficiency, the first disease-modifying therapy for debilitating hemolytic anemia. Its lead product candidate in its portfolio, PYRUKYND (mitapivat), is an activator of both wild-type and mutant pyruvate kinase, or PK, enzymes for the potential treatment of hemolytic anemias. It is also developing tebapivat, a novel PK activator, for the potential treatment of lower-risk myelodysplastic syndromes, or LR MDS, and hemolytic anemias; AG-181, its phenylalanine hydroxylase, or PAH, stabilizer for the potential treatment of phenylketonuria, or PKU; and AG-236, an siRNA in-licensed from Alnylam Pharmaceuticals, Inc., targeting the transmembrane serine protease 6, or TMPRSS6 gene for the potential treatment of polycythemia vera, or PV.

Mitapivat Shows Significant Hemoglobin Improvement in Sickle Cell Disease
- Significant Efficacy Improvement: In the 52-week RISE UP Phase 3 trial, mitapivat demonstrated a statistically significant improvement in hemoglobin response, with 40.6% of patients achieving a ≥1.0 g/dL increase compared to placebo, highlighting its potential in treating sickle cell disease.
- Reduction in Transfusion Burden: New analyses revealed a 41.1% reduction in the proportion of patients requiring blood transfusions in the mitapivat group, alongside a 55.9% decrease in average red blood cell units transfused per patient, which not only alleviates treatment burden but may also reduce dependence on supportive care.
- Clinically Meaningful Benefits: Among hemoglobin responders in the mitapivat group, there was a 26% reduction in the annualized rate of sickle cell pain crises and a 34% decrease in related hospitalizations, along with a 53% reduction in emergency room visits, indicating significant improvements in patient quality of life.
- Well-Tolerated Safety Profile: Mitapivat exhibited a safety profile consistent with previous trials, with similar rates of treatment-emergent adverse events between the mitapivat and placebo groups, demonstrating its good tolerability in patients with sickle cell disease.

Agios Halts Development of LR-MDS Drug Tebapivat
- Clinical Trial Results: Agios announced that its drug tebapivat for lower-risk myelodysplastic syndromes (LR-MDS) did not meet the predefined clinical advancement threshold in the Phase 2b trial, which, while showing biological activity, failed to demonstrate clinical benefit in a sufficient proportion of patients, leading to the decision to halt further development.
- Patient Population Characteristics: The trial enrolled 65 patients with LR-MDS, evaluating different doses (10mg, 15mg, 20mg) of tebapivat in a heavily pretreated and heterogeneous population, highlighting the biological complexity of the disease and the challenges in identifying patients likely to benefit.
- Safety Assessment: Although tebapivat was well tolerated across all dose levels with no new safety signals identified, the lack of observed clinical benefit necessitated Agios's decision to discontinue further development in LR-MDS.
- Future Outlook: Agios remains optimistic about tebapivat's potential in sickle cell disease, with topline data from the Phase 2 trial expected in the second half of 2026, continuing to explore its applications in other rare hematologic diseases.
