Brief description of study
What is the purpose of this study?
The purpose of this placebo-controlled study is to determine how well ferric citrate will lower the level of FGF23, 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. Ferric citrate is an oral medication that is approved by the U.S. Food and Drug Administration (FDA) for use in adults with kidney disease to control serum phosphate levels, but it has not been approved for use in children. The use of ferric citrate is considered investigational, which means it has not been approved for the way it is being used in this study.
THIS STUDY IS ENROLLING BY INVITATION ONLY
Detailed description of study
What will happen during the study?
- Participants will be randomly assigned by a computer program to one of two groups (like a flip of a coin); ferric
- citrate or placebo.
- Researchers use a placebo to see if the study drug works better or is safer than taking nothing.
- You have an equal chance (50:50) of receiving placebo or active study drug.
- You will continue to receive your Standard of Care medications you are currently taking.
This study will test the following in children with CKD stages 3-4:
• The effectiveness of ferric citrate in lowing blood levels of FGF23.
• How well ferric citrate is tolerated over a 12-month period.
• The effects of ferric citrate on anemia, bone mineral metabolism and kidney function over a 12-month period.
