This clinical trial is focused on studying a disease called Systemic Lupus Erythematosus (SLE), which is a condition where the immune system mistakenly attacks healthy tissues in the body. The study is specifically looking at children and adolescents aged 5 to under 18 years who have moderate to severe active SLE. The treatment being tested is called Anifrolumab, also known by its code name MEDI-546. Anifrolumab is given as an intravenous infusion, which means it is administered directly into the bloodstream through a vein.
The purpose of this study is to determine the right dose of Anifrolumab for young participants and to ensure that it is safe and effective for them. Participants in the study will receive either Anifrolumab or a placebo, which is a substance that looks like the treatment but does not contain the active ingredient. The study will take place over a period of time, during which participants will receive regular infusions and be monitored for any changes in their condition and overall health.
Throughout the study, researchers will collect information on how the body processes Anifrolumab and how it affects the symptoms of SLE. This includes looking at how well the treatment works in reducing disease activity and any potential side effects. The study aims to provide valuable insights into the use of Anifrolumab for treating SLE in children and adolescents, contributing to better management of this challenging condition.
