12 mai 2026 mis à jour par: argenx

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
