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
Registered, but not yet taking participants.

The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
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 phase 2 trial tested a drug called eculizumab in 16 people with anti-GBM disease, a severe autoimmune condition that often leads to kidney failure. The drug blocks a part of the immune system believed to cause kidney damage. Researchers measured how many patients avoided dialysis or kidney transplant, and tracked kidney function changes.

What this could mean

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

Active substance
Eculizumab (a drug that blocks a part of the immune system called complement C5)
What this could lead to
If it works, this could offer a new treatment option for anti-GBM disease, potentially reducing the need for dialysis or kidney transplant.
What could go wrong
This is a small, early-phase trial with only 16 people, so results may not apply to everyone. The drug also increases risk of serious infections like meningitis.
