ClinConnect Summary
This clinical trial is investigating a medication called ravulizumab to see how safe and effective it is for children and teenagers with Neuromyelitis Optica Spectrum Disorder (NMOSD), a rare condition that affects the nervous system. The trial is currently looking for participants who are between specific ages and have tested positive for a particular antibody related to NMOSD. To join, participants must have experienced at least one attack or relapse in the past year and have a certain level of disability. It’s important that they have not received certain treatments recently and are up to date on vaccinations to prevent infections.
If your child is eligible and decides to participate, they will receive ravulizumab and be closely monitored by the study team for any side effects or changes in their condition. This study will help researchers understand how well ravulizumab works in children with NMOSD and contribute to better treatment options in the future. If you have any questions or want to know more about the trial, it’s a good idea to talk to your doctor.
