Primary Outcome Measures

Efficacy Endpoint : Responder Rate at End of Study (EOS) Visitweek 48 (End-of-Study)

Since the study was prematurely terminated and an important number of subjects early withdrawn, the responder rate is biased and consequently not interpretable.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.
