Study population: This study will recruit patients diagnosed with MG by a physician. The diagnosis of MG patients newly diagnosed prior to enrollment should be based on the clinical characteristics of MG and at least one of the following criteria: (a) Positive serology tests for acetylcholine receptor antibody (AChR Ab), muscle-specific kinase antibody (MuSK Ab), or lipoprotein-related protein 4 (LRP4 Ab); (b) Results of electrophysiological studies (repetitive stimulation, single-fiber electromyography, or both) related to synaptic transmission disorder at the neuromuscular junction; (c) Positive pharmacological test results (such as neostigmine methylsulfate test). Previously diagnosed patients must have a documented MG diagnosis accepted by clinical physician.
Who may be able to join
- This study will enroll patients of all ages who are diagnosed with MG of all MGFA classifications by physicians.
- Patients must have the following data to be enrolled in this study:
- MGFA classification
- MG-ADL score
- MG patients or their legal guardians/representatives are able to sign the Informed Consent Form (ICF).
Who cannot join
- Patients aged ≥18 years with ocular myasthenia gravis (MGFA class I) lasting for more than 2 years;
- Patients who are currently participating in an interventional clinical trial cannot be enrolled in this study.

About this study
Official title: A Multicenter, Prospective Cohort Study in Patients With Myasthenia Gravis in China
This study is a multi-center, prospective cohort study designed to characterize current clinical practice, clinical and patient-reported outcomes (PROs), disease prognosis, treatment patterns and healthcare resource utilization for Chinese patients with myasthenia gravis (MG). This study will enroll patients with MG as diagnosed by physician. Approximately 1,200 MG patients are intended to be recruited from approximately 40 sites across majority of regions in China. The clinical and PROs included MGFA class, MGFA PIS, MG-ADL (Activities of Daily Living), QMG (Quantitative MG score), MG QOL-15R, EQ-5D etc. All MG patients enrolled will be followed up every 6 months until end of 2027.

Where is the study taking place?
The record lists 20 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Clinical outcome (time frame: Every 6 months up to 3 years). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2026.
