Summary

This trial is testing a new drug to see if it can help kids with a disease that causes muscle weakness.

Who is the study for?
This trial is for children aged 6 to <18 with refractory generalized Myasthenia Gravis (gMG), who have had stable treatment regimens and are vaccinated against certain infections. It's not for those pregnant, on other trials recently, previously treated with eculizumab, or having recent thymectomy.
What is being tested?
The study tests Eculizumab's effectiveness in treating pediatric gMG by observing changes in disease severity scores. This open-label trial will also assess the drug’s safety and how it interacts with the body over time.
What are the potential side effects?
While specific side effects aren't listed here, Eculizumab may cause reactions at the infusion site, increase infection risk due to immune system impact, and potential interference with blood clotting.
