A Study to Evaluate Pharmacokinetics, Efficacy, Safety, Tolerability, and Pharmacodynamics of Satralizumab in Pediatric Patients With Aquaporin-4 Antibody Positive Neuromyelitis Optica Spectrum Disorder (NMOSD) (SAkuraSun)
A Phase III, Multicenter, Open-Label, Uncontrolled Study to Evaluate Pharmacokinetics, Efficacy, Safety, Tolerability, and Pharmacodynamics of Satralizumab in Pediatric Patients With AQP4 Antibody Positive Neuromyelitis Optica Spectrum Disorder (NMOSD)
This study will primarily evaluate the pharmacokinetics of satralizumab in pediatric patients aged 2-11 years with anti-aquaporin-4 (AQP4) antibody seropositive neuromyelitis optica spectrum disorder (NMOSD). Efficacy, safety, tolerability, and pharmacodynamics will be evaluated in a descriptive manner, given the small number of patients who will be enrolled in this study.
