Summary

This trial will assess the effects of therapy with FC on changes in iFGF23 levels in 160 pediatric patients with CKD stages 3-4. Participants will be randomized to one of the two groups: 1) FC or 2) FC placebo.

Who is the study for?
This trial is for children aged 6-17 with moderate chronic kidney disease (stages 3-4) who have normal phosphate levels and can swallow tablets. They should be on stable doses of certain medications like growth hormone or iron supplements for at least two weeks before the study starts, and they must be able to eat at least two meals a day.
What is being tested?
The trial is testing if ferric citrate (FC) affects a hormone called iFGF23 in kids with kidney disease over a year. It's a double-blind study, meaning neither the participants nor the researchers know who gets FC or placebo. Kids are randomly chosen to get either FC or fake pills that look like FC.
What are the potential side effects?
Possible side effects from ferric citrate may include digestive issues such as diarrhea or constipation, nausea, vomiting, and potential changes in blood tests related to iron levels.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Treatment ArmExperimental Treatment1 Intervention
During the 12-month trial, participants will be given a fixed weight-based dose of Ferric Citrate (FC). The full medication dose will be 3g/day for participants weighing \<31 kg, 5g/day for those weighing \>31 - \<51 kg, and 6g/day for participants \>51 kg. These doses will be divided into three doses to be taken with meals.
Group II: Control ArmPlacebo Group1 Intervention
During the 12-month trial, participants will be given a fixed weight-based dose of Placebo. The full medication dose will be 3g/day for participants weighing \<31 kg, 5g/day for those weighing \>31 - \<51 kg, and 6g/day for participants \>51 kg. These doses will be divided into three doses to be taken with meals.
