Phase III Clinical Trial of NPB-01 in Patients With Guillain-Barré Syndrome

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02221271
Recruitment Status : Completed

Brief Summary:

Patients diagnosed with Guillain-Barré syndrome were confirmed based on the diagnostic criteria for Guillain-Barré syndrome. Patients who meet all inclusion criteria and do not conflict with the exclusion criteria will receive NPB-01 (intravenous immunoglobulin) 400mg/kg/day for five consecutive days.

Patients evaluate the Functional Grade(FG) and Arm Grade(AG) et al.

As a safety endpoint, the safety of NPB-01 will be investigated the occurrence of adverse events by the start of the study treatment.
