Primary
| Measure | Time frame |
|---|---|
| Main Objective: - Evaluate the efficacy of eculizumab in the treatment of pediatric refractory generalized myasthenia gravis (gMG);Secondary Objective: - Evaluate the safety and tolerability of eculizumab in the treatment of pediatric refractory gMG - Evaluate the efficacy of eculizumab in the treatment of pediatric refractory gMG - Evaluate MGFA Post-Interventional Status over time - Describe the total number and percentage of patients with clinical deteriorations, myasthenic crises, and rescue therapy use over time - Describe the pharmacokinetics (PK) and pharmacodynamics (PD) of eculizumab treatment in pediatric refractory gMG patients ;Primary end point(s): Change from Baseline in the QMG total score over time regardless of rescue treatment;Timepoint(s) of evaluation of this end point: 26 Weeks | — |
