This Phase 3 study will be a double-blind, double-dummy, noninferiority, and superiority design with sample size re-estimation. This study has 2 parts: Part A will evaluate efficacy and safety of riliprubart during a 24 week, randomized, double-blinded treatment period; Part B will evaluate long-term efficacy, safety, and tolerability of riliprubart during a 24 week open-label treatment period. This Phase 3 trial will include IVIg-treated participants, randomized with a 1:1 ratio to either receive riliprubart or continue IVIg (active comparator) in Part A and then switch to receive open-label riliprubart in Part B.
