NCT ID NCT06606886
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 4 trial tested two drugs—hydroxyurea and metformin—in 96 people with transfusion-dependent beta-thalassemia. Participants took one of the two drugs for a year. Researchers measured changes in fetal hemoglobin levels and how often blood transfusions were needed. The goal was to see if either drug could reduce transfusion dependence and improve quality of life.
