Summary
This trial is testing a drug to see if it is safe and effective for long-term use in treating myasthenia gravis.
Who is the study for?
This trial is for individuals with generalized myasthenia gravis who have previously participated in specific antecedent studies. They must be able to consent, use contraception, and not be pregnant or breastfeeding. Excluded are those allergic to the study drug or its components, recently had major surgery, have serious infections or diseases that could affect results or safety.
What is being tested?
The trial tests the long-term safety of Efgartigimod PH20 SC (a subcutaneous injection) for treating myasthenia gravis. It looks at how well it works over time, its effects on quality of life and daily activities, and if patients can self-administer the treatment.
What are the potential side effects?
Potential side effects may include reactions at the injection site, changes in immune system function due to lowered IgG levels which might increase infection risk; however specific side effect profiles will be monitored throughout the study.
