Phase III Clinical Trial of NPB-01maintenance Therapy in Patients With Chronic Inflammatory Demyelinating Polyneuropathy.
NPB-01(Intravenous Immunoglobulin) Maintenance Therapy for Patients With Chronic Inflammatory Demyelinating Polyneuropathy.
Patients diagnosed with Chronic Inflammatory Demyelinating Polyneuropathy were confirmed based on the European Federation of Neurological Societies/ Peripheral. Nerve Society Guideline. 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. Subsequently, patients receive NPB-01 1g/kg every 3weeks and evaluate the Inflammatory Neuropathy Cause and Treatment(INCAT) score and INCAT sensory sumscore(ISS) et al.
As a safety endpoint, the safety of NPB-01 will be investigated the occurrence of adverse events by one year after the start of the study treatment.

- 2. Patients with evidence of stroke, central nerve system trauma, or persistent neurological deficits due to peripheral neuropathy from other causes(diabetic neuropathy, IgM paraproteinaemia, uraemic neuropathy, toxic neuropathy, hereditary neuropathy)
- 3. Patients with evidence of neuropathy or alcoholic neuropathy or vitamin deficiency neuropathy due to myeloma, lymphoma, sarcoidosis, systemic lupus erythematosus, malignancy, vasculitis, Crow-Fukase syndrome, Sjögren syndrome.
- 4. Patients with multifocal motor neuropathy.
- 5. Patients treated with plasmapheresis at 3 months before informed consent.
- 6. Patients treated with rituximab at 6 months before informed consent.
- 7. Patients treated with high-dose intravenous immunoglobulin(greater than or equal to 1g/kg) at 8 weeks before informed consent.
- 8. Patients treated with intravenous immunoglobulin at 3 weeks before informed consent.
