Is this trial a fit for you?

Likely a good fit

Adults (18+) with documented gMG who are AChR-antibody positive and for whom their treating physician has decided to start efgartigimod alfa as part of routine care.

Probably not a fit

Patients not experiencing meaningful changes in MG symptoms or who discontinue therapy for non-medical reasons may see limited benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study collects real-world data from Italian patients with AChR-antibody positive generalized MG who are treated with efgartigimod as part of standard care. Data are gathered at baseline, 6 months, and 12 months, with additional medical chart information covering MG history, therapies, exacerbations, hospitalizations, and prior MG events in the year before baseline. The primary aim is to describe clinical outcomes and patient-reported experiences in routine practice over up to 23 months. No interventional procedures are mandated by the study, and treatment decisions are made independently of participation. Results will provide real-world evidence on how efgartigimod impacts disease burden and patient quality of life in Italy.

Why it matters

Potential benefit: If successful, the study could clarify how efgartigimod affects daily living and disease burden for adults with gMG in real-world care.

How similar studies have gone: Real-world observational studies of efgartigimod in MG have shown feasibility and generated useful safety and outcome signals in routine practice.
