Key inclusion criteria

1. Patients with definite CIDP diagnosed according to the modified diagnostic criteria of the European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) (2010) by the time of enrollment in the study
2. Patients meeting one of the following conditions:
1) Patients with positive serum IgG4 autoantibody (CNTN-1 or NF-155) confirmed by the time of enrollment in the study
2) Patients with negative serum IgG4 autoantibody (CNTN-1 and NF-155) confirmed by the time of enrollment in the study
3. Patients with refractory CIDP not responding adequately to treatment with corticosteroids for 12 weeks, and intravenous immunoglobulin therapy (IVIg) for 8 weeks by the time of enrollment in the study, or those who are unable to administer or continue corticosteroids and IVIg
4. Patients with total adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) Disability Scale scores of 2 to 8 at both preliminary enrollment and enrollment, and with the total score at enrollment equal to or worse than that at preliminary enrollment
5. Patients aged 12 years or older at informed consent
6. Patients who give their voluntary written consent after having received adequate information on this study

Key exclusion criteria

1. Patients with disease meeting one of the following exclusion criteria defined in the modified EFNS/PNS diagnostic criteria.
2. Patients who have started or have increased the dose of corticosteroids for CIDP within 12 weeks prior to the enrollment
3. Patients who have started or have increased the dose of IVIg within 8 weeks prior to the enrollment
4. Patients who have undergone plasmapheresis within 8 weeks prior to the enrollment or patients with refractory disease not responding adequately to 8 weeks of plasmapheresis (plasma exchange or double-filtration plasmapheresis)
5. Patients who have started or have increased the dose of an immunosuppressant within 12 weeks prior to the enrollment
6. Patients who have undergone hematopoietic stem cell transplant prior to the enrollment
7. Patients who have used rituximab prior to the enrollment

9. Patients with poorly controlled diabetes
10. Patients who have or are suspected to have active infection
11. Patients tested positive for HBs antigen, HBs antibody, HBc antibody, and/or HCV antibody(patients with positive HBs antibody or HBc antibody can be enrolled when a HBV-DNA test is negative, and hepatitis B virus-DNA and aspartate/alanine transaminase levels are monitored at fixed intervals), or patients with positive HIV antibody or HTLV-1 antibody
12. Patients with leukopenia, neutropenia, or lymphopenia
13. Patients with history of serious hypersensitivity or anaphylactic reaction to one of the ingredients in the investigational drug or murine protein-containing products
14. Patients with serious comorbidity
