Summary

This trial aims to determine if riliprubart is effective for treating CIDP in adults compared to the current standard treatment, IVIg. The study will last for up to 109 weeks

Who is the study for?
This trial is for adults with Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) who have responded to IVIg treatment in the past. They must meet specific diagnostic criteria, have a stable dose of IVIg, and some ongoing disability from CIDP. Vaccinations against certain bacteria are required, and participants must agree to use contraception.
What is being tested?
The study tests Riliprubart's effectiveness compared to standard IVIg treatment in managing CIDP symptoms over up to 109 weeks. Participants will be randomly assigned either the new drug or usual treatment and monitored for changes in their condition.
What are the potential side effects?
While not specified here, side effects may include reactions similar to those experienced with IVIg such as headache, nausea, muscle pain, fever or chills; plus any additional risks associated with Riliprubart which would be detailed by the study.
