A Double-blind, Randomized, Multi-Center Study Investigating Efficacy and Safety of Two Different Dosages of Intravenous Human Normal Immune Globulin (IGIV) 10% KIg10 (QIVIGY) in Participants With Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)
Kedrion S.p.A.
Summary
The current study is being conducted to assess the efficacy and safety of KIg10 (Intravenous Human Immune globulin 10%) at two different dosages as maintenance therapy for Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) following 21 weeks of treatment.
Description
This is a Double Blind, Randomized study. All subjects will enter a wash-out phase of up to 12 weeks, or until functional deterioration, defined as an increase of ≥1 point (worsening) in the adjusted INCAT disability score, is demonstrated. Eligible subjects will then be randomized in a 1:2 ratio to receive either 0.5 g/kg or 1.0 g/kg KIg10 at 3-weekly intervals for 21 weeks. Subjects who relapse during randomized treatment due to functional deterioration, based on the INCAT score, will be rescued with 2.0 g/kg KIg10 at 3-weekly intervals for 21 weeks.
