- •(5) Patients with CIDP (maintenance therapy cohort): Patients on IVIg/SCIg maintenance therapy who have responded to IgG administration (Patients receiving IVIg 0.4 to 1.2 g/kg every 2 to 6 weeks for the past 12 weeks from the time of eligibility confirmation or SCIg 80 to 480 mg/kg every 1 to 2 weeks for the past 12 weeks from the time of eligibility confirmation).
- •(6) Patients with CIDP (acute treatment cohort): Patients with an INCAT (Inflammatory Neuropathy Cause and Treatment) score between 2 and 9 of disability at the time of eligibility confirmation (but with a lower limb disability score of 2 or more, if the upper limb disability score is 1).
- •(7) Patients with CIDP (maintenance therapy cohort): Patients with an INCAT score between 0 and 7 at the time of eligibility confirmation and a previous disability with an INCAT score between 2 and 9 (but with a lower limb disability score of 2 or more, if the upper limb disability score is 1).
- •(8) In the case of using therapeutic agents * for CIDP and MMN within 30 days prior to eligibility confirmation, the patients who continue without adding and increasing dosage and require treatment with the test product.

- •(5) Patients with neuropathy secondary to internal diseases such as diabetes mellitus, cancer, collagen disease, amyloidosis, or infection such as Borrelia burgdorferi infection (Lyme disease), diphtheria (Eligible if there is no diabetic neuropathy, HbA1c level is stable and blood glucose control can be maintained appropriately).
- •(6) Patients with drugs, biological products, chemotherapy or toxicant induced neuropathy.
- •(7) Patients who have received maintenance therapy with IVIg/SCIg for more than 52 weeks (maintenance therapy cohort only) (however, patients who received maintenance therapy with IVIg/SCIg for more than 52 weeks may also be enrolled if immunoglobulin administrations are considered necessary based on medical judgment).
- •Patients with MMN
- •(8) Patients with CIDP
- •(9) Patients with other neuromuscular diseases (e.g., hereditary motor neuropathy, motor neuron disease, neuromuscular junction disease, muscle disease, diabetic neuropathy, cervical spondylosis, lumbar spondylosis, hereditary neuropathy with liability to pressure palsies, peripheral nerve tumor, vasculitic neuropathy, sarcoid neuropathy, etc.). However, patients with those diseases that are considered NOT to affect outcomes or evaluations during the study in the investigator's opinion can be enrolled.
- •Patients with CIDP/MMN
- •(10) Patients with central demyelinating diseases such as multiple sclerosis.
- •(11) Patients with chronic illnesses or central nervous system disorders (e.g. stroke, Parkinson's disease, amyotrophic lateral sclerosis, etc.) that may cause neurological symptoms or signs.

- •(12) Patients who have an active malignancy requiring chemotherapy and/or radiation therapy, or have a medical history of malignancy and have been in complete remission for less than 2 years prior to eligibility confirmation. Exceptions to this exclusion criterion are appropriately treated basal cell or squamous cell carcinoma of the skin, intraepithelial carcinoma of the cervix, and stable prostate cancer not requiring treatment.
- •(13) For the most recent IVIg treatment, those who received >1.2 g/kg and <= 2.4 g/kg IVIg treatment within 9 weeks before eligibility confirmation, >=0.75 g/kg and <=1.2g/kg IVIg treatment within 6 weeks, or <0.75 g/kg within 3 weeks (excluding patients with CIDP (maintenance therapy cohort)). Otherwise, blood IVIg level* is >=0.375 g/kg at the time of eligibility confirmation.
- •Blood IVIg level is calculated based on the dosage of IVIg treatment within 15 weeks before eligibility confirmation and its half-life (21 days).
- •(14) Patients who received SCIg in excess of 480 mg/kg as a single dose 4-5 weeks (22-35 days) prior to eligibility confirmation, patients who received SCIg in excess of 240 mg/kg as a single dose (480 mg/kg total) 3-5 weeks (15-35 days) prior to eligibility confirmation, patients who received SCIg in excess of 120 mg/kg as a single dose (480 mg/kg total) 2-5 weeks (8-35 days) prior to eligibility confirmation (but must not have received SCIg 1 week (1-7 days) prior to eligibility confirmation) (excluding patients with CIDP (maintenance therapy cohort)).
