A Study of TAK-411 in Adults With Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP)
NCT06798012
Recruiting
CIDP is an autoimmune disease. This means that the body's germ fighting (immune) system attacks itself. In CIDP, the immune system attacks the protective covering around the nerves called myelin. Over time, these nerves lose their ability to send signals to the muscles in the body. This leads to muscle weakness and loss of sensation in arms and legs among other symptoms. Participants with CIDP can be treated with a protein called immunoglobulin (or IG). TAK-411 is a special type of immune globu... Read More
