About the Study

CKD stages 3–4 (decreased kidney function): A study of an oral medication called ferric citrate.

This study is being done for children: • Age 6-18 years old • Diagnosed with CKD stages 3–4 • age-appropriate normal serum phosphate levels. The purpose of this study is to determine how well ferric citrate (Oral medication) will lower the level of FGF23 (a hormone that regulates phosphate levels in the blood), maintain or correct anemia and iron levels in the blood, and maintain normal levels of serum phosphate in children with CKD stages 3 and 4, that is, between 15% and 60% of normal function. CKD is a condition in which kidney function is decreased.
