Primary Outcome Measures

Name	Time	Method
Change From Baseline to Week 13 (Day 85) in Inflammatory Rasch-built Overall Disability Scale (iRODS) Score	From Baseline up to Week 13 (Day 85)	iRODS is a linearly weighted patient-reported outcome measure (questionnaire) that captures activity and social participation limitations in participants with chronic inflammatory demyelinating polyradiculoneuropathy. Questionnaire consisted of 24 items (including eating, taking a shower, walking a flight of stairs, standing for hours, etc.) and assesses a participant's ability to perform daily and social activities. Participants had 3 response options: 0=impossible to perform; 1=performed with difficulty; 2=easily performed, performed without difficulty. Raw sum scores of iRODS (range 0 to 48, where 0=worse and 48=best) were translated to log odds units (logits) scale, placing participant' estimates on same logit scale, which had a score range of -6.95 (most severe activity and social participation restrictions) to 8.11 (no activity and social participation limitations). A positive change is associated with a better outcome of less disease activity and more social activity.
