Agios develops oral, disease‑modifying therapies that target metabolic enzymes to treat rare hemolytic anemias and phenylketonuria. By leveraging its expertise in cellular metabolism, the company creates PK activators and PAH stabilizers that improve red blood cell durability and normalize phenylalanine levels, offering long‑term benefits for patients and their clinicians.

Problem
Patients with rare hemolytic anemias and related metabolic disorders have few effective treatment options, leading to chronic symptoms, reduced red blood cell lifespan, and limited quality of life.
Solution
Agios leverages its deep expertise in cellular metabolism to develop oral, disease‑modifying therapies that target key metabolic enzymes such as pyruvate kinase (PK) and phenylalanine hydroxylase (PAH). By activating PK, its candidates increase ATP production, lower 2,3‑DPG levels, and improve red blood cell durability, addressing the underlying cause of hemolytic anemia. The company also pursues PAH stabilizers to normalize phenylalanine levels in phenylketonuria, enabling patients to increase natural protein intake. These therapies are designed to provide long‑term benefits rather than merely palliative relief, and are advanced through a structured pipeline from discovery to regulatory submission.
Target Audience
Primary customers are patients with rare hemolytic anemias (including PK deficiency, sickle cell disease, thalassemia) and phenylketonuria, as well as the hematologists, geneticists, and specialty clinics that treat these conditions.
