A Study to Evaluate the Impact of Efgartigimod on Overall Disease Experience of People Suffering From Generalized Myasthenia Gravis (gMG) in Italy

Non-interventional, Longitudinal Hybrid Data Sources Study to Evaluate the Impact of Efgartigimod on Overall Disease Experience of People Suffering From Generalized Myasthenia Gravis (gMG) in Italy

This study aims to generate real world evidence (RWE) from Italian clinical practice on the impact of efgartigimod alfa in gMG patients encompassing clinical outcomes and patient reported experiences.

The study population will consist in adult patients with a documented diagnosis of gMG who are AChR-antibody positive and for whom the decision of treatment with efgartigimod alfa for gMG has been made independently of study participation as part of routine clinical care.

The total study duration will be up to 23 months

Primary data collection will be performed during the baseline visit and follow-up will be at month 6 and 12 after baseline.

Secondary data collection from medical charts, information on myasthenia gravis (MG) related therapies (including rescue therapies), MG exacerbations, and MG-related hospitalizations will be collected for the 12 months preceding baseline. Additionally, the patient's MG history and overall medical history will be documented.

Inclusion Criteria:

• At least 18 years old at signing of informed Consent Form (ICF) and privacy form (PF)
• Documented diagnosis of gMG
• AChR-antibody positive
• The treating physician has decided to initiate efgartigimod alfa as part of routine clinical care and in accordance with product labelling, independently from the study

Exclusion Criteria:

• Hypersensitivity to the active substance or to any of the excipients listed: sodium dihydrogen phosphate, monohydrate; disodium hydrogen phosphate, anhydrous; arginine hydrochloride; polysorbate 80, hyaluronidase, histidine, histidine hydrochloride monohydrate, methionine, polysorbate 20, sucrose.
• Current or planned participation in an interventional clinical trial.
