What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tested the drug eculizumab in 25 children and adults in China with a rare kidney condition called atypical hemolytic uremic syndrome (aHUS). The goal was to see if the drug could stop blood clots and improve kidney function. All participants received eculizumab intravenously, and researchers measured blood cell counts and kidney markers to assess response.

What this could mean

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

Active substance
eculizumab
What this could lead to
If successful, this could confirm eculizumab as a safe and effective treatment for aHUS in Chinese patients, helping control the disease and prevent kidney damage.
What could go wrong
This is a small, single-arm study with no placebo group, so results may not be definitive. Eculizumab requires lifelong treatment and carries risks like serious infections.
