Current Primary Outcome: Efficacy endpoint : Responder rate at end of study (EOS) visit [ Time Frame: 48 weeks after first treatment administration ]

Responder Rate at EOS visit. Responders are defined as patients 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.



Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Adjusted INCAT disability score [ Time Frame: 48 weeks ]
    Changes from baseline to 24 weeks (Visit V9) and EOS visit in the adjusted INCAT disability score.
  • Responder rate at 24 weeks [ Time Frame: 24 weeks ]
  • Time to relapse [ Time Frame: 48 weeks ]
  • Grip strength [ Time Frame: 48 weeks ]
    changes from baseline to 24 weeks (Visit V9) and EOS visit in Grip strength
  • Rasch-built Overall Disability Scale (R-ODS) [ Time Frame: 48 weeks ]
    changes from baseline to 24 weeks (Visit V9) and EOS visit in Rasch-built Overall Disability Scale (R-ODS)
  • Medical Research Council (MRC) sum score [ Time Frame: 48 weeks ]
    changes from baseline to 24 weeks (Visit V9) and EOS visit in Medical Research Council (MRC) sum score
