New pill shows promise for anemia in kids with kidney disease
NCT ID NCT05682326
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a drug called daprodustat in children aged 3 months to under 18 years who have anemia due to chronic kidney disease. The goal was to see how the drug moves through the body and if it is safe. Only 4 children took part, and they received the drug for up to 52 weeks. The study looked at side effects and changes in red blood cell levels.
