Summary

This study is a long-term extension of earlier trials testing the drug riliprubart in adults with CIDP, a condition where the immune system attacks the nerves, causing weakness and numbness. About 300 participants who completed a prior riliprubart study will continue receiving the drug for up to 3 years to see if it remains safe and effective. The goal is to see if riliprubart can help prevent relapses and manage the disease over time.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

riliprubart (a drug given as a subcutaneous injection)

What this could lead to

If successful, this could show that riliprubart is a safe and effective long-term treatment option for people with CIDP, potentially reducing relapses and the need for other therapies.

What could go wrong

This is an extension study, so participants already know the drug works for them. It is not a placebo-controlled trial, so results may not apply to all CIDP patients. Long-term side effects are still being monitored.
