What this Trial Is About

Researchers are assessing the safety and tolerability of subcutaneous administration of rozanolixizumab in children aged 2 to under 18 years who have moderate to severe generalized Myasthenia Gravis (gMG). This open-label, single-arm study aims to evaluate the activity, safety, and pharmacokinetics of rozanolixizumab in this pediatric population. Participants must have a documented diagnosis of gMG with specific autoantibodies and have an unsatisfactory response to existing treatments. Participants will receive predefined doses of rozanolixizumab for a 6-week treatment period. The study does not include a placebo or comparison group. Rozanolixizumab is given as a solution for injection under the skin. The study includes monitoring for safety and drug activity, including measurement of drug levels and antibody responses. During the study, participants will be regularly assessed for treatment-emergent adverse events, antibody levels, and changes in their Myasthenia Gravis symptoms using daily living and quantitative scores. Assessments will occur up to 18 weeks from baseline, covering treatment and observation periods. Safety monitoring includes evaluation of adverse events and local tolerability at scheduled visits. The total participation duration is up to 18 weeks, including treatment and follow-up.
