Safety, Tolerability, and Efficacy of NVG-2089 in Participants With CIDP
Trial Parameters
Brief Summary
The purpose of the study is to evaluate the safety of NVG-2089 and to evaluate how well patients respond to this investigational treatment. NVG-2089 is a new drug that is being developed for treating patients with CIDP. NVG-2089 is designed to mimic the effects of a protein called IVIg. NVG-2089 is designed to potentially help the immune system by attaching (binding) to certain receptors in the body and activating them, which helps reduce inflammation and supports how the immune system works.

Treatment-experienced participants: 2-7 at screening Note: A score of 2 should be exclusively from leg disability component of adjusted INCAT. For participants with an adjusted INCAT score of ≥3 (and up to 7 for treatment-experienced; no upper limit for treatment-naïve) at study entry, there are no specific requirements for arm or leg scores. * Treatment-experienced participants: Participants who were treated with IVIg/SCIg at the time of screening must have documented evidence within 24 months of screening of: 1.
