Is this trial a fit for you?

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

What this trial studies

This observational registry collects long-term data on patients diagnosed with generalized myasthenia gravis (gMG) who are being treated with Alexion C5 inhibition therapies, such as eculizumab and ravulizumab. Participants will provide retrospective medical history and treatment data at enrollment, followed by prospective data collection through routine clinical care and patient-reported outcomes. The registry aims to gather information over a period of up to five years to assess clinical outcomes and safety of these therapies.
