Monitor the Evolution of Myasthenia Gravis Symptoms in Real-life in Patients With Anti-AChR and Anti-MUSK Generalised Myasthenia Gravis in Therapy With RYSTIGGO® (Rozanolixizumab) (REAL MG PRO)

31 augustus 2026 bijgewerkt door: Centre Hospitalier Universitaire de Nice

An Observational, Prospective, Multicenter, Open-label Study to Monitor the Evolution of Myasthenia Gravis Symptoms in Real-life in Patients With Anti-AChR and Anti-MUSK Generalised Myasthenia Gravis in Therapy With RYSTIGGO® (Rozanolixizumab)

Generalized Myasthenia Gravis (gMG) is a rare autoimmune disease (a disease in which the body attacks its own tissues) that causes muscle weakness and significant fatigue.

Current treatments (corticosteroids, plasma exchange, intravenous immunoglobulin infusions) improve symptoms in many patients. However, many continue to suffer from fatigue and fatigability that are not well measured by standard tools. Moreover, these treatments can cause significant long-term side effects, reducing quality of life.

New treatments such as Rozanolixizumab (ROZ) are now available. They act rapidly and are well tolerated, allowing better symptom control while reducing the risks associated with conventional treatments.

To properly evaluate these new treatments, it is essential to understand patients' perspectives on their effectiveness. The scales used by physicians do not always capture all the symptoms experienced by patients, particularly fatigability. This is why a new tool has been developed: the MG symptoms PRO. This questionnaire allows patients to assess their own symptoms (fatigue, weakness of the eyes, mouth, breathing, muscle fatigability) in detail.

This research aims to better understand the effectiveness of treatments from the patients' perspective in order to improve their care.

The goal of the study is to evaluate the impact of Rozanolixizumab administration in real-world practice through the MG symptoms PRO questionnaire. This is an observational study, meaning that the medication is prescribed by the physician according to current regulations, and the study simply collects routine medical data during your follow-up, over a period of approximately 9 months.
