Hematopoietic Stem Cell Transplantation in Chronic Inflammatory Demyelinating Polyneuropathy

Chronic inflammatory demyelinating polyneuropathy is disease believed to be due to immune cells, cells which normally protect the body, but are now attacking the nerves in the body. As a result, the affected nerves fail to respond, or respond only weakly, to stimuli causing numbing, tingling, pain, and progressive muscle weakness.The likelihood of progression of the disease is high. This study is designed to examine whether treating patients with high dose cyclophosphamide (a drug which reduces the function of the immune system) and ATG (a protein that kills the immune cells that are thought to be causing disease), followed by return of the previously collected blood stem cells will stop the progression of CIDP. Stem cells are undeveloped cells that have the capacity to grow into mature blood cells, which normally circulate in the blood stream. The purpose of the high dose cyclophosphamide and ATG is to destroy the cells in the immune system. The purpose of the stem cell infusion is to evaluate whether this treatment will produce a normal immune system that will no longer attack the body.

  Show Detailed Description


Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion criteria:

  • Definite CIDP according to the EFNS / PNS criteria


  • Clinically typical or atypical CIDP


  • Failure to tolerate or respond to, or an incomplete response to, or relapse after at least 3 months of conventional treatment consisting of corticosteroids (equivalent dosage of prednisone 1.0/mg/day to 0.75mg/kg/day to start with adequate tapering trials of no less than 0.5mg/kg/day), and/or either IVIG or plasmapheresis or cytoxan or rituxan
  • Failure to respond to therapy is defined by:

    1. Persistent muscle weakness Grade 3/5 or worse (MRC) in at least one muscle or grade 4/5 in at least two muscle groups OR
    2. Persistent dysphagia documented by either aspiration or insufficient clearing on videofluoroscopic examination.


    3. Persistent incapacitating sensory loss (e.g. gait ataxia, falls > 1/month)


    4. If patients are on IVIG or plasmapheresis, neurologic condition is documented to deteriorate (for example, new or increase finger tip paresthesias or increased leg heaviness) upon stopping IVIG (or plasmapheresis)@
  • Monoclonal gammopathy of undetermined significance (MUGS) (in which the pathogenesis of are thought to be the same as CIDP) will be allowed provided bone marrow aspirate and biopsy rules out multiple myeloma.
  • Other immune mediated or suspected immune mediated neuropathies such as multifocal motor neuropathy or anti-MAG neuropathy may be treated but will be analyzed and reported separately.

Exclusion Criteria:

  • Any evidence of hereditary cause for neuropathy that is known or likely hereditary demyelination neuropathy because of family history, foot deformity, mutilation of hands or feet, retinitis pigmentosa, ichthyosis, or liability to pressure palsies.
  • Diphtheria, drug, or toxin exposure likely to be cause of neuropathy
  • Conditions in which the pathogenesis of the neuropathy may be different from CIDP such as: Lyme disease (Borrelia burgdorferi infection), POEMS syndrome, Osteosclerotic myeloma, malignancies such as Waldenstrom macroglobulinemia, and Castleman's)
  • Multiple myeloma
  • HIV positive
  • Insulin dependent Diabetes mellitus
  • Chronic active hepatitis
  • Age > 65 years old or < 18 years old
  • Significant end organ damage such as (not caused by CIDP):

    1. LVEF <40% or deterioration of LVEF during exercise test on MUGA or echocardiogram.
    2. Untreated life-threatening arrhythmia.
    3. Active ischemic heart disease or heart failure or myocardial infarction within the last 6 months
    4. DLCO <40% or FEV1/FEV < 50%
    5. Serum creatinine >2.0.
    6. Liver cirrhosis, transaminases > 2 x of normal limits or bilirubin >2.0 unless due to Gilbert disease.
  • Prior history of malignancy except localized basal cell or squamous skin cancer or other localized cancer considered cured only by surgery
  • Positive pregnancy test, inability or unwillingness to pursue effective means of birth control, or failure to willingly accept or comprehend irreversible sterility as a side effect of therapy.
  • Psychiatric illness or mental deficiency making compliance with treatment or informed consent impossible.
  • Inability to give informed consent.
  • Major hematological abnormalities such as platelet count less than 100,000/ul or ANC less than 1000/ul.
  • Failure to collect at least 2.0 x 106 CD34+ cells by apheresis and, if necessary, bone marrow harvest is a contraindication to treatment, i.e., receiving the conditioning regimen.
