Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Male or female patient aged 18 years or more.
  2. Responder patient who have completed the last visit of PRISM I10E-1302 study defined as a patient with a decrease ≥1 point in the adjusted INCAT disability score between baseline and the end-of-study (EOS) visit of PRISM I10E-1302 study.
  3. Covered by national healthcare insurance system as required by local regulations.
  4. Written informed consent obtained prior to any study-related procedures.

Exclusion Criteria:

  1. History of severe allergic reaction or serious adverse reaction to any Ig.
  2. Known hypersensitivity to human Ig or to any of the excipients of I10E (glycine and polysorbate 80).
  3. History of cardiac insufficiency (New York Heart Association (NYHA) III/IV), uncontrolled cardiac arrhythmia, unstable ischemic heart disease, or uncontrolled hypertension.
  4. History of venous thromboembolic disease, myocardial infarction or cerebrovascular accident.
  5. Risk factor for blood hyperviscosity such as cryoglobulinemia or haematological malignancy with monoclonal gammopathy.
  6. Body mass index (BMI) ≥40 kg/m².
  7. Glomerular filtration rate <80 mL/min/1.73m² measured according to the Modified Diet Renal Disease (MDRD) calculation.
  8. Any other ongoing disease that may cause chronic peripheral neuropathy, such as toxin exposure, dietary deficiency, uncontrolled diabetes, hyperthyroidism, cancer, systemic lupus erythematosus or other connective tissue diseases, infection with HIV, Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV), Lyme disease, multiple myeloma, Waldenström's macroglobulinaemia, amyloidosis, and hereditary neuropathy.
  9. Woman with positive results on a urine pregnancy test or breastfeeding woman or woman of childbearing potential without an effective contraception.
  10. Any other serious medical condition that would interfere with the clinical assessment of CIDP or use of I10E or prevent the patient from complying with the protocol requirements.
  11. Increasing dosage or introduction of a systemic corticosteroids therapy within the last 3 months prior to screening, at a dose higher than 10 mg daily prednisolone or equivalent. Topical corticosteroids are permitted.
  12. Treatment within 12 months prior to screening with immunomodulatory or immunosuppressant agents (including but not limited to cyclophosphamide, cyclosporine, interferon-α, interferon-β1a, anti-CD20, alemtuzumab, aziathioprine, etanercept, mycophenolate mofetil and methotrexate) or haemopoetic stem cell transplantation.
  13. Plasma exchange, blood products or derivatives administered within the last 3 months prior to screening.
  14. Anticipated poor compliance of patient with study procedures.

Outcomes

Primary Outcome Measures

Efficacy Endpoint : Responder Rate at End of Study (EOS) Visit
Since the study was prematurely terminated and an important number of subjects early withdrawn, the responder rate is biased and consequently not interpretable. Responders were defined as subjects with either: No change or decrease in the adjusted INCAT disability score and without any change in CIDP treatment between baseline and EOS visit. OR An increase by 1 point in the adjusted INCAT disability score without requirement of any change in CIDP treatment between baseline and EOS visit.
