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.

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.
