- Primary Outcome Measures
Name Time Method Main Objective: To evaluate the long-term safety and tolerability of ARGX-113 in acetylcholine receptor antibody (AChR-Ab) seropositive patients.;Secondary Objective: To evaluate the long-term safety and tolerability of ARGX-113 in the overall population (AChR-Ab seropositive and AChR-Ab seronegative patients).;Primary end point(s): Incidence and severity of AEs, serious adverse events (SAEs), vital signs,<br>electrocardiogram (ECG) and laboratory assessments over the duration of the trial in AChR-Ab seropositive patients.;Timepoint(s) of evaluation of this end point: up to maximum 3 years
