Phase IIIII Study of B001 Injection to Treat Aquaporin-4 Antibody Positive Neuromyelitis Optica Spectrum Disorder

What this Trial Is About

Researchers are evaluating the effectiveness and safety of B001 injection in patients who have neuromyelitis optica spectrum disorder NMOSD and test positive for aquaporin-4 antibodies. This condition involves recurrent attacks affecting the nervous system. The study is a multicenter, randomized, double-blind, placebo-controlled trial conducted in phases II and III to understand how well B001 works and how safe it is for these patients. Participants will receive intravenous doses of either B001 or a placebo on Day 1 and Day 15 during the randomized controlled period. The study includes two groups one receiving B001 injections and the other receiving placebo injections matching B001s schedule. The trial will extend over several years, monitoring patients closely for disease relapse and treatment side effects. During the study, participants will be regularly assessed for the time to their first NMOSD attack, changes in disability status, vision acuity, and opticospinal function. Researchers will also observe the annual relapse rate and document any adverse events. The trial includes safety monitoring for about three years to ensure comprehensive data collection on treatment impact and participant health.
