NCT ID NCT00772382

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study tested the long-term safety of a drug called MCI-196 (Colestilan) in 116 adults with stage 5 chronic kidney disease who are on dialysis and have high phosphorus levels. Participants took flexible doses of the drug for 52 weeks. The main goal was to see how many side effects occurred, and the study also checked if the drug helped lower phosphorus levels over time.

Our plain-language read of the trial. This is informational only โ€” not medical advice or a prediction.

Active substance
MCI-196 (also known as Colestilan or Colestimide), a drug taken as a tablet to lower phosphorus levels
What this could lead to
If successful, this could confirm MCI-196 as a safe long-term option to control phosphorus levels in dialysis patients, helping manage a common complication of kidney disease.
What could go wrong
This is a completed phase 3 trial, but it only looked at safety and basic effectiveness in 116 people. Results may not apply to all dialysis patients, and side effects are possible.
