Trial Summary

What is the purpose of this trial?

This study tests whether riliprubart can help adults with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) whose disease has not responded to standard treatments like IVIg, SCIg, or corticosteroids. Participants are randomly assigned to receive either riliprubart or placebo for 24 weeks, after which all participants can continue into an open-label extension where everyone receives riliprubart.

Why do researchers think this study treatment might be promising?

Riliprubart targets inflammation pathways differently than traditional CIDP therapies by blocking C1s, a part of the immune system that can harm nerves in CIDP. By acting on this specific immune pathway, the study drug may offer more targeted relief for people whose CIDP has not responded to current standards of care.
