Summary

This trial aims to test how well and how safe it is for patients to use the zilucoplan auto-injector on themselves.

Who is the study for?
This trial is for adults with generalized Myasthenia Gravis (gMG) who are either currently in a zilucoplan study or have been on a stable dose of commercial zilucoplan. Participants must be vaccinated against meningitis, not pregnant, willing to use contraception, and able to self-administer the drug using an auto-injector.
What is being tested?
The trial is testing how effective and safe it is for participants with gMG to use an auto-injector device to self-administer zilucoplan, which is a medication used to treat their condition.
What are the potential side effects?
While specific side effects are not listed here, typically such trials would monitor for any adverse reactions related to the drug's administration including injection site reactions, potential allergic responses, and general medication-related side effects.
