Phase III Clinical Trial of NPB-01maintenance Therapy in Patients With Chronic Inflammatory Demyelinating Polyneuropathy.

January 17, 2016 updated by: Nihon Pharmaceutical Co., Ltd

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.
