Frequently asked questions about Etavopivat

What is etavopivat used for?

Etavopivat is an investigational oral medicine being studied for sickle cell disease and thalassemia, two inherited blood disorders. It is also being evaluated in liver diseases. It is not approved for any use and remains in clinical development.

How does etavopivat work?

Etavopivat is a small molecule activator of PKLR, the gene encoding pyruvate kinase in red blood cells. Activating this enzyme target is intended to improve red blood cell energy metabolism and survival, which is the rationale for studying it in sickle cell disease and thalassemia.

Who makes etavopivat?

Etavopivat is developed by Novo Nordisk A/S, which trades under the ticker NVO. Novo Nordisk is the sponsor responsible for the clinical development program across sickle cell disease, thalassemia, and liver diseases.

What phase is etavopivat in?

Etavopivat is in Phase 1 development overall, with nine trials recorded and five currently active. Four trials have been completed. It is investigational and has not been approved by the FDA or any other regulator.

What clinical trials is etavopivat in?

Etavopivat is being studied in sickle cell disease and thalassemia trials including NCT06612268, a Phase 3 study in sickle cell disease, and NCT06609226, a Phase 3 long-term treatment study. Earlier completed Phase 1 studies include NCT07023029 and NCT06813924 in healthy participants.

Is etavopivat the same as etavopivat tablets or etavopivat low dose?

Yes. Etavopivat tablets, etavopivat low dose, etavopivat tablets low dose, and the labels etavopivat A, etavopivat B, and etavopivat C all refer to the same investigational drug, etavopivat, developed by Novo Nordisk.
