Study Endpoints

Primary Endpoints

Percentage (%) of Subjects With CIDP Relapse or Are Withdrawn for Any Other Reason During the Subcutaneous (SC) Treatment Period
Up to 25 weeks

Relapse is defined as an increase of at least 1 INCAT score point (except for the increase from 0 to 1 in the upper limb score). The INCAT score is a 10-point scale that covers the functionality of legs and arms, and has been successfully used to measure treatment effects in various CIDP studies. Scores for arm disability range from 0 ("No upper limb problems") to 5 ("Inability to use either arm for any purposeful movement"), and scores for leg disability range from 0 ("Walking not affected") to 5 ("Restricted to wheelchair, unable to stand and walk a few steps with help"). The INCAT (total) score is the sum of these 2 scores and ranges from 0 to 10. For the "adjusted" INCAT score, changes in the function of the upper limbs from 0 (normal) to 1 (minor symptoms) or from 1 to 0 were not recorded as deterioration or improvement because these changes are not considered clinically significant.
