. Patients meeting one of the following conditions:
. Patients with refractory CIDP not responding adequately to treatment with corticosteroid 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 corticosteroid and IVIg
. 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
. Patients aged 12 years or older at informed consent
. Patients who give their voluntary written consent after having received adequate information on this study (legally acceptable representatives should also give consent for underage patients, and informed assent should be obtained from children aged 12 to 15)
Exclusion criteria

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Rate of patients with improvement in adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability scale
. Patients who have started or have increased the dose of corticosteroid for CIDP within 12 weeks prior to the enrollment
. Patients who have started or have increased the dose of IVIg within 8 weeks prior to the enrollment
. Patients who have underwent 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)
. Patients who have started or have increased the dose of an immunosuppressant (azathioprine, cyclophosphamide, cyclosporine, mycophenolate mofetil, interferon alpha, interferon beta, etanercept, methotrexate, mitoxantrone, alemtuzumab, cladribine, tacrolimus, fingolimod) within 12 weeks prior to the enrollment
. Patients who have underwent hematopoietic stem cell transplant prior to the enrollment
. Patients who have used rituximab (genetical recombination) prior to the enrollment
. Patients who have participated in another clinical study within 3 months prior to the enrollment (enrollment is allowed for those participating in a clinical study in the range of Indications or Dosage and Administration in Japan) or patients who are participating in another study
