The purpose of this study is to summarize the percentage of participants achieving age-specific Kidney Disease Outcomes Quality Initiative (KDOQI) targets for serum phosphorus in hyperphosphatemic children and adolescents with chronic kidney disease (CKD) who are on dialysis, following 8 weeks of treatment with lanthanum carbonate.
Lanthanum Carbonate 1500 mg to 3000 mg powder will be administered orally.
Calcium carbonate will be administered orally at a total daily dose based on standard clinical practice. The total daily dose may be adjusted as appropriate, until the target serum phosphorus level is achieved or until a maximum daily dose of 6500 mg is reached.
