Conditions
Brief summary
This study will carry out to assess the efficacy of GB-0998 (intravenous immunoglobulin;400mg/kg/day for five days) in the treatment of the Guillain-Barré Syndrome based on the changes in Hughes Functional Grade (FG) as primary endpoint, and in addition, to assess the safety of GB-0998.
