About this trial
The goal of this clinical trial is to learn if ripertamab works to treat chronic inflammatory demyelinating polyneuropathy. It will also learn about the safety of ripertamab. The main questions it aims to answer are:
Does ripertamab reduce the risk of recurrence in patients? What medical problems do participants have when taking ripertamab? Researchers will compare ripertamab to a placebo (a look-alike substance that contains no drug) to see if ripertamab works to treat chronic inflammatory demyelinating polyneuropathy.
Participants will:
A single intravenous infusion of drug ABC or placebo. Visit the clinic for checkups and tests during W1, W2, W4, W8, W12 Keep a diary of their symptoms and the number of times they undergo rescue therapy
