Incidence and Predictors of Early Clinical Relapse Within Six Months After Thymectomy in Patients With Myasthenia Gravis

Myasthenia gravis is an autoimmune disorder affecting neuromuscular transmission, characterized by fluctuating muscle weakness and fatigue. Surgical removal of the thymus gland (thymectomy) is an established treatment to help achieve disease control in eligible patients. However, surgery does not guarantee permanent remission, and some individuals experience disease recurrence or clinical worsening. The main objective of this observational study is to determine the incidence and clinical predictors of early relapse occurring within the first six months following thymectomy. The study evaluates adult patients with confirmed autoimmune myasthenia gravis who underwent thymectomy at Assiut University Hospitals. Patient characteristics, antibody profiles, pre-surgical disease severity, and postoperative follow-up assessments at 1, 3, and 6 months will be analyzed to identify factors associated with early clinical relapse.

Evaluation of the Condition of Patients Receiving EARLY Ravulizumab and Admitted in ICU for gMG Crisis

Myasthenia Gravis (MG) is a rare autoimmune disease that causes muscle weakness and fatigue. It occurs when the immune system produces antibodies that block communication between nerves and muscles. In some patients, the disease can suddenly worsen and cause severe breathing problems. This life-threatening situation is called a myasthenic crisis and requires immediate treatment in an intensive care unit (ICU). During such crises, patients may need to receive respiratory assistance through a ventilator. These episodes are often long and can lead to complications such as infections or heart problems. To manage a myasthenic crisis, doctors usually use treatments that remove or neutralize the harmful antibodies: plasma exchange (PLEX) or intravenous immunoglobulin (IVIg). Although both are effective, recovery can be slow, and many patients remain in the ICU for several weeks. Ravulizumab (Ultomiris®) is a new medicine that targets a specific part of the immune system called the complement system, which contributes to muscle damage in MG. It is already approved for adults with generalized MG who have anti-acetylcholine receptor (AChR) antibodies. Ravulizumab is given by intravenous infusion every eight weeks. Clinical studies have shown that it can improve symptoms within one week of starting treatment. Some doctors have started using ravulizumab early, after PLEX or IVIg, for patients hospitalized in the ICU for a myasthenic crisis. Early use of this treatment could help reduce the duration and severity of the crisis, leading to faster recovery and shorter hospital stays. However, there is currently no national study that systematically collects data on this approach. The EARLY-MG study aims to describe the condition and recovery of patients who receive ravulizumab early during a myasthenic crisis requiring ICU admission. The study will not test an experimental treatment or change medical care. It is an observational study. The main hypothesis of the study is that early administration of ravulizumab, after PLEX or IVIg, may help patients recover faster, improve muscle strength, and reduce complications and hospital stay. Around 30 adult patients with generalized MG and anti-AChR antibodies will be enrolled in 10 centers across France. Each patient will be followed for 26 weeks (about six months). Assessments will be performed at the start of the study and at weeks 2, 4, 10, 18, and 26. Investigators will collect information such as: * Duration of stay in the ICU and in the hospital after receiving ravulizumab * Duration of mechanical ventilation, if needed * Clinical improvement using standard evaluation scales (Myasthenia Gravis Activities of Daily Living, MG Foundation of America classification, and Garches' score) * Occurrence of any complications or additional treatments The study will last about 18 months in total, including one year for patient inclusion and six months of follow-up per patient. The results may help guide future recommendations and improve patient care in France and worldwide.

Investigation of the Effects of Proprioceptive Neuromuscular Facilitation Exercises in Patients With Myasthenia Gravis

The goal of this clinical trial is to investigate of the effects of proprioceptive neuromuscular facilitation exercises on fatigue, muscle strength and functional parameters in patient with Myasthenia Gravis. The main questions it aims to answer are: * Do proprioceptive neuromuscular facilitation exercises reduce fatigue in patients with Myasthenia Gravis? * Do proprioceptive neuromuscular facilitation exercises increase muscle strength in patients with Myasthenia Gravis? * Do proprioceptive neuromuscular facilitation exercises improve functional parameters in patients with Myasthenia Gravis? * How well can patients with Myasthenia Gravis tolerate proprioceptive neuromuscular facilitation exercises? Participants will be divided into 2 groups as control group and exercise group with block randomization method. In this single-blind randomized controlled study, the participants in the control group will be placed on a waiting list without any intervention during the 6-week study period and at the end of the study, the interventions applied to the exercise group will be applied exactly the same. Proprioceptive neuromuscular facilitation exercises will be applied to the exercise group 3 days a week, 1 hour a day for 6 weeks. Individuals will be evaluated at the beginning and at the end of the study. Researchers will compare exercise and control group to see if there are effects of proprioceptive neuromuscular exercises patients with Myasthenia Gravis.

AXIS MG Patient Registry

The goal of the AXIS Autoimmune Neurology Registry is to learn about the experiences of adults living with autoimmune neurological disorders, starting with myasthenia gravis (MG), over time. The main questions the registry aims to answer are: * How do symptoms, daily functioning, and quality of life change over time? * What treatments do participants use, and how are these treatments related to their symptoms and health? * What challenges do participants experience with treatment, including side effects, treatment burden, missed doses, and access to care? Participants will: * Join the registry and complete an enrollment survey (online or through a mobile app) * Complete a brief online survey about their MG approximately once a month * Provide information that can help confirm their MG diagnosis * Optionally, share their medical records with the research team This is an observational study. The registry will not assign treatments or ask participants to change their medical care. Information collected through the registry may help researchers better understand MG and improve future research and care.

A Study to Evaluate the Safety and Preliminary Efficacy of SYS6020 CAR T-cells in Patients With Refractory Generalized Myasthenia Gravis

The DLT observation period is 28 days after receiving SYS6020 injection. The participants will not undergo lymphodepleting chemotherapy. The efficacy and safety profile of the participants will be continuously assessed during the trial. Efficacy measurement includes the MG-ADL, QMG, MGC, MG-QoL 15R scale, MGFA clinical classification, and MGFA post-intervention state (MGFA PIS) grading scales, as well as self-antibodies, etc. Safety measurement includes vital signs, physical examination, laboratory tests, cytokines, and ECG, etc. The adverse events and concomitant therapy will be continuously collected during the trial. In addition, during the study period, blood samples will be collected from participants who have received SYS6020 treatment for PK/PD test, and immunogenicity test. For the dose-escalation phase, 3 to 5 dose levels are proposed to be explored. The Safety Monitoring Committee (SMC) will discuss the safety data and make a decision if the next SYS6020 injection could be initiated or dose-escalation could be initiated. After the completion of the dose-escalation phase, the recommended doses would be determined for dose-expansion phase. For the dose-expansion phase, further safety and efficacy data will be collected among the participants who will receive the recommended dose of SYS6020 injection.

Pregnancy Registry, Infants, Serum/Milk Analysis (PRISMA)

PRISMA, is a pregnancy registry study, focused on comprehensively collecting information about pregnancy in women with chronic neurological conditions from across the United States and internationally. Depending on their specific condition (MS, CIS, NMOSD, or other) and their specific treatment, participants will be asked to contribute to different aspects of the study. (1) The biosamples will be blood, breast milk, infant stool, maternal stool and vaginal swab samples, collected at specific time points. (2) The online surveys will be collected at specific time points. All study activities will be discussed with participants upon enrollment. By collecting this information, the investigators hope to gain deeper insights into the relationship between pregnancy, the neurological condition, and maternal and infant health. For example, one of the sub-studies focuses on breast milk collection for women planning postpartum treatment with Ocrevus, Rituxan, Briumvi or Kesimpta. This study is fully remote and all sample collection is optional, so participants can choose which types of samples they wish to provide. For blood draws, participants can schedule a home visit through ExamOne, making participation even more convenient. The investigators aim to enroll women with chronic neurological conditions who are planning pregnancy, currently pregnant, or within one year postpartum.
