简要总结
The goal of this clinical trial is to evaluate the safety and effectiveness of Efgartigimod in patients with Guillain-Barre syndrome (GBS). The main questions it aims to answer are:
Is Efgartigimod a safe treatment option for GBS patients? Does treatment with Efgartigimod improve patient outcomes?
Participants will:
Take drug Efgartigimod or Intravenous Immunoglobulin during hospitalization Undergo six blood draws in six follow-up study visits to evaluate the concentration of IgG Keep a diary of their symptoms and drugs using at the same time

入选标准
- •Aged 18-70 years
- •Diagnosis of sensorimotor or pure motor Guillain-Barré syndrome (GBS) based on the 2023 EAN/PNS guidelines (corresponding to classical GBS in the Chinese Guidelines for the Diagnosis and Treatment of Guillain-Barré Syndrome 2024).
- •Onset of GBS within 14 days
- •GBS Disability Scale (GBS-DS) score of 3 to 5
排除标准
- •Patients with other diagnoses cannot be excluded
- •Patients with recurrent GBS
- •Patients with more than 14 days after onset of symptoms
- •GBS DS of 2 or less
- •Patients unable to cooperate with scale assessments due to psychiatric disorders or impaired consciousness
- •Positive serum test at screening for an active viral infection with any of the following conditions: Hepatitis B virus (HBV) that is indicative of an acute or chronic infection; Hepatitis C virus (HCV) based on HCV antibody assay; Positive HIV serology at screening
- •Patients with any known severe bacterial, viral or fungal infection or any major episode of infection that required hospitalization or injectable antimicrobial therapy in the last 8 weeks prior to Screening
- •Total IgG level ≤ 6 g/L at screening
- •Concomitant diseases that can cause peripheral neuropathy, such as metabolic neuropathies (e.g., diabetes, alcoholism), connective tissue disease-associated neuropathies (e.g., rheumatoid arthritis, Sjögren's syndrome, systemic lupus erythematosus), or trauma, which may confound the trial results
- •Subjects with serious underlying diseases, such as cardiac dysfunction, coagulopathy dysfunction
- •Pregnant and lactating women, and those intending to become pregnant during the trial or within 90 days after the last dosing
- •Patients who have a history of malignancy, including malignant thymoma, or myeloproliferative or lymphoproliferative disorders, unless deemed cured by adequate treatment with no evidence of recurrence for ≥ 3 years before Screening. Patients with completely excised non-melanoma skin cancer (such as basal cell carcinoma or squamous cell carcinoma) or cervical carcinoma in situ would be permitted at any time
- •Use of investigational drug within 3 months or 5 half-lives of the drug (whichever is longer) prior to Screening
- •Use of immunosuppressants, monoclonal antibodies, or other immunomodulatory drugs within 6 months prior to enrollment; use of corticosteroids at a dose exceeding 20 mg within 3 months prior to enrollment; or use of IVIG or plasma exchange (PE) within 1 month prior to enrollmen
