What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing mitapivat, a drug that may help improve anemia by making red blood cells healthier and last longer. It targets patients with a specific type of thalassemia who don't need regular blood transfusions but still suffer from anemia.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but if you are taking hydroxyurea, your dose must be stable for at least 16 weeks before joining. If you are on strong CYP3A4/5 inhibitors or inducers, or anabolic steroids, you must stop them for a certain period before starting the trial.
