Key inclusion & exclusion criteria

Inclusion Criteria:

- Age at onset 18 - 65 years.

- The presence of asymmetrical limb weakness at onset or motor involvement having a
motor nerve distribution in at least two peripheral nerve distributions, predominant
upper limb involvement, disabling weakness MRC grade 4 or less in at least one muscle.

- Decreased or absent tendon reflexes in affected limbs.

- Electrophysiological evidence of one site with definite motor conduction block or one
site with probable conduction block according to previously defined criteria.

- Response to SCIG according to criteria that were described in previous studies

- On SCIG maintenance treatment for more than 3 months preceding the study.

- Patients have given written informed consent, prior to the study, with the
understanding that consent may be withdrawn at any time without prejudice.

Exclusion Criteria:

- Bulbar signs or symptoms.

- Upper motor neuron signs (spasticity, hyperreflexia, extensor plantar response).

- Sensory symptoms and signs with sensory deficits on examination (except for vibration
sense) and abnormal results of sensory nerve conduction studies

- Other neuropathies (e.g. diabetic, lead, porphyric or vasculitic neuropathy, chronic
inflammatory demyelinating polyneuropathy, Lyme neuroborreliosis, post radiation
neuropathy, hereditary neuropathy with liability to pressure palsies,
Charcot-Marie-Tooth neuropathies, meningeal carcinomatosis).

- Treatment with other immunosuppressive drugs (cyclophosphamide, azathioprine,
cyclosporin) in the 6 months preceding the study.

- Female patient who is pregnant or breast-feeding or of childbearing potential.

- Confirmation that the patient is not pregnant will be established by a negative b-HCG
test within a 7-day period before inclusion in the study. Lack of childbearing
potential is met by a) being post-menopausal, b) being surgically sterile, c)
practising contraception with an oral contraceptive, intra-uterine device, diaphragm
or condom with spermicide or d) being sexually inactive.

- Age < 18 years
