Phase 3 Study of Empasiprubart IV to Evaluate Safety and Effectiveness in Adults With Chronic Inflammatory Demyelinating Polyneuropathy CIDP

What this Trial Is About

Researchers are evaluating the efficacy and safety of empasiprubart in adults with Chronic Inflammatory Demyelinating Polyneuropathy CIDP. This Phase 3, randomized, double-blinded, placebo-controlled study compares empasiprubart to placebo to better understand its impact on CIDP symptoms and disease progression. The study has two parts Part A lasts 24 weeks 6 months, where participants receive either empasiprubart or placebo via intravenous infusion. After Part A, all participants enter Part B for 96 weeks 24 months during which everyone receives empasiprubart. Participants who received empasiprubart in Part A will receive a placebo dose once during Part B to maintain the study blind. Participants will have regular assessments including measurements of disability using the adjusted inflammatory neuropathy cause and treatment aINCAT score, grip strength, and other neurological and quality of life scales. Safety is monitored throughout the study. The total participation period spans up to 120 weeks, with evaluations at multiple time points to track changes from baseline and any adverse events.
