A Study to Evaluate the Clinical Outcomes of Efgartigimod PH20 SC in Adults With New-onset Generalized Myasthenia Gravis (gMG)

Clinical trial: Efgartigimod PH20 SC for new generalized myasthenia gravis.

Recruiting
18 years and older
All
Phase 4

This study looks at how well a new medicine, efgartigimod PH20 SC, works for adults with new-onset generalized myasthenia gravis (gMG). gMG is a condition where muscles get weak because the immune system attacks them. "New-onset" means the person has had symptoms for less than a year. This study lasts about 58 weeks.

Key Points:

  • The study lasts for approximately 58 weeks, including 51 weeks of treatment.
  • Participants need to have had generalized MG symptoms for less than 1 year.
  • Participants shouldn't have used certain medicines or had specific surgeries related to gMG before the study.
