NCT ID NCT00359684

First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 2 times

Summary

Cystinosis is a rare inherited disease that causes kidney failure and poor growth due to cystine buildup in cells. This study follows 330 patients taking cysteamine, a drug that lowers cystine levels, to track long-term effects, detect new complications, and support genetic research. The goal is to better manage the disease and improve patient outcomes.

What this could mean

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

Active substance

cysteamine

What this could lead to

If successful, this study could confirm cysteamine's long-term safety and effectiveness in managing cystinosis, potentially improving growth and reducing organ damage.

What could go wrong

This is an observational follow-up, not a controlled trial, so it cannot prove cysteamine works. Cystinosis remains a serious disease with no cure, and long-term complications may still occur.
