Study 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.Check my eligibility
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.See study design
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.

Answered by AI

Who might be able to take part in this particular clinical research?

"This clinical trial is seeking 11 participants, aged 6 to 17, who have myasthenia gravis. In addition to this primary condition, patients must also: a) have tried one or more immunosuppressive therapies for at least a year with no success; b) require maintenance plasma exchange or intravenous immunoglobulin treatments to control symptoms; c) be significantly impacted by myasthenia gravis despite current treatment options; d) have a total score of 12 or higher on the Quantitative Myasthenia Gravis scale (for patients aged 12-18). Male and female pediatric participants are both eligible for this"

Answered by AI

What other research is there on this topic?

"As of now, there are 14 ongoing studies being conducted for Eculizumab in 121 different cities and 42 countries. The first trial happened in 2016 and was completed by Alexion Pharmaceuticals.
