Universal STAR-T Cell Injection in Generalized Myasthenia Gravis

This is a Phase I, single-arm, open-label, dose-escalation and dose-expansion study. This is an exploratory clinical study of universal STAR-T cell injection in patients with refractory generalized myasthenia gravis (GMG). Approximately 10-24 participants aged 18-65 years (inclusive) with the condition are planned to be enrolled. The primary objective is to evaluate the safety, tolerability, preliminary efficacy, pharmacokinetic/pharmacodynamic (PK/PD) profile, and immunogenicity of universal STAR-T cell injection. The starting dose is 1.5E6 STAR+ T cells/kg, administered as a single intravenous infusion.Based on safety, PK results, and preliminary efficacy data obtained from the initial dose cohorts, a recommended dose will be selected for subsequent dose-expansion studies to further systematically evaluate the safety and efficacy of universal STAR-T cell injection. This study includes the screening period (from D-28 to D-6), the pre-clearance treatment and rest observation period (from D-5 to D-1), the cell infusion and main study endpoint observation period (from D0 to W12 after infusion), and the follow-up period (from W12 after infusion to W104). The study is being conducted at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology.

A Study to Test How Safe Pozelimab and Cemdisiran Combination Therapy and Cemdisiran Alone Are and How Well They Work in Adult Patients With Generalized Myasthenia Gravis

This study is researching the experimental drugs called pozelimab and cemdisiran, and cemdisiran monotherapy. The study is focused on patients with generalized Myasthenia Gravis (gMG). Myasthenia gravis is a disease that causes weakness and fatigue in muscles in the body because the nerves and muscles are not communicating properly. The aim of the study is to see how effective pozelimab and cemdisiran are when used in combination and when pozelimab and cemdisiran are used alone for patients with gMG. The study is looking at several other research questions, including: * What side effects may happen from taking the study drugs * How the study drugs work inside the body * How much of the study drugs are in the blood at different times * Whether the body makes antibodies against pozelimab and cemdisiran (which could make the drugs less effective or could lead to side effects)

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.

Phase 3 Study to Assess the Efficacy and Safety of Batoclimab as Induction and Maintenance Therapy in Adult Participants With Generalized Myasthenia Gravis

The purpose of this 4-period study is to confirm the efficacy and safety of batoclimab in participants with gMG. In Period 1, participants will be randomized 1:1:1 to receive batoclimab 680 milligrams (mg) subcutaneously (SC) once a week (QW) or 340 mg SC QW or placebo. The primary efficacy endpoint will be assessed by change in the myasthenia gravis activities of daily living (MG- ADL) score in acetylcholine receptor antibody seropositive (AChRAb+) participants. In Period 2, participants previously treated with batoclimab will be re-randomized to stay on batoclimab (340 mg SC QW or 340 mg SC every two weeks) or receive placebo treatment. The secondary endpoint of maintenance of efficacy will be assessed by change in the MG- ADL score in AChRAb+ participants. Participants demonstrating a response to batoclimab during either Period 1 or 2 may enter the long-term extension (Period 3). Participants who complete Period 3 are eligible to participate in Period 4 (Optional Long-Term extension) according to their treatment assignment in Period 3.
