Basic Information

• Recruitment status: Complete
• Health condition(s) or Problem(s) studied: hyperphosphatemia
• Date of first enrollment: 13/02/2017
• Target sample size: 200
• Study type: Interventional

Intervention(s)

1) Sucroferric oxyhydroxide 750 to 3,000mg/day
12months medication
Serum phosphorus value treatment goal 6.0mg/dL less than 5.0mg/dL or more
2) Lanthanum carbonate 750 to 2,250mg/day
12months medication
Serum phosphorus value treatment goal 6.0mg/dL less than 5.0mg/dL or more
3) Sucroferric oxyhydroxide 750 to 3,000mg/day
12 months medication
Serum phosphorus value treatment goal 4.5mg/dL less than 3.5mg/dL or more
4) Lanthanum carbonate 750 to 2,250mg/day
12 months medication
Serum phosphorus value treatment goal 4.5mg/dL less than 3.5mg/dL or more

Outcome(s)

• Primary Outcome: rate of change in CACS

Secondary Outcome

1. changes in CACS,
2. changes in serum phosphate and calcium levels,changes in calcium phosphate product, and the ratio of patients who reached the target serum phosphate level,
3. changes in the level of intact parathyroid hormone (PTH), intact fibroblast growth factor (FGF)-23, and c-terminalFGF23,
4. effects on the renal anemia, assessed by transferrin saturation(TSAT), hemoglobin, and the changes in the dose of iron and EPO administration,
5. relationship between serum phosphate level and CACS,
6. average doses of phosphate binder required to achieve the target serum phosphate level,
7. safety issue (adverse drug reactions).
