Primary Outcome Measures :
- Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) [ Time Frame: From Baseline until End of Study (up to Week 60) ]A TEAE is defined as an AE starting on or after the time of first administration of investigational medicinal product (IMP) or any unresolved event already present before the first administration of IMP that worsened in intensity following exposure to IMP, up to 8 weeks after the last dose of IMP in study participants who discontinued the study or IMP.
- Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) Leading to Permanent Withdrawal of Study Medication [ Time Frame: From Baseline until End of Study (up to Week 60) ]A TEAE is defined as an AE starting on or after the time of first administration of IMP or any unresolved event already present before the first administration of IMP that worsened in intensity following exposure to IMP, up to 8 weeks after the last dose of IMP in study participants who discontinued the study or IMP.
Secondary Outcome Measures :
- Change From Baseline in Myasthenia Gravis-Activities of Daily Living (MG-ADL) Total Score at Each Scheduled Assessment During Treatment and Observation Periods [ Time Frame: Baseline, Weeks 5, 7, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 52 and 60 ]The Myasthenia Gravis Activities of Daily Living (MG-ADL) is an 8-item patient-reported outcome (PRO) instrument developed on the basis of the Quantitative Myasthenia Gravis (QMG). The MG-ADL targeted symptoms and disability across ocular, bulbar, respiratory, and axial symptoms. The total MG-ADL score was obtained by summing the responses to each individual item (8 items; Grades: 0, 1, 2, 3), where 0 represents no symptoms or impaired performance and 3 represents the most severe symptoms or impaired performance. The total score ranges from 0 to 24, with a higher score indicating more disability. A positive change indicates worsening and a negative change indicates improvement.
- Change From Baseline in Myasthenia Gravis-Composite (MG-C) Total Score at Each Scheduled Assessment During Treatment and Observation Periods [ Time Frame: Baseline, Weeks 5, 7, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 52 and 60 ]MG-C scale is a validated assessment and scale tests 10 items with individual items being weighted differently. The items included ptosis/upward gaze (range: 0 [>45 second] - 3 [Immediate]), double vision on lateral gaze (range: 0 [>45 second] - 4 [Immediate]), eye closure (range: 0 [Normal] - 2 [severe weakness]), talking (range: 0 [Normal] - 6 [difficult to understand speech]), chewing (range: 0 [Normal] - 6 [gastric tube]), swallowing (range: 0 [Normal] - 6 [gastric tube]), breathing (range: 0 [Normal] - 9 [ventilator dependence]), neck flexion (range: 0 [Normal] - 4 [severe weakness]), shoulder abduction (range: 0 [Normal] - 5 [severe weakness]) and hip flexion (range: 0 [Normal] - 5 [severe weakness]), lower scores= lower disease activity. Total MG-C score was obtained by summing responses to each individual item and score ranges from 0 to 50, with lower scores indicating lower disease activity. A positive change indicates worsening and a negative change indicates improvement.
- Change From Baseline in Quantitative Myasthenia Gravis (QMG) Total Score at Each Scheduled Assessment During Treatment and Observation Periods [ Time Frame: Baseline, Weeks 5, 7, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 52 and 60 ]The QMG is a validated assessment and the scale tested 13 items, including ocular and facial involvement, swallowing, speech, limb strength, and forced vital capacity. The total QMG score was obtained by summing the responses to each individual item (13 items; Responses: None=0, Mild=1, Moderate=2, Severe=3) and the score ranges from 0 to 39, with lower scores indicating lower disease activity. A positive change indicates worsening and a negative change indicates improvement.
- Percentage of Participants Using Rescue Medication (Intravenous Infusion of Immunoglobulin G (IVIg) or Plasma Exchange (PEX)) [ Time Frame: From Baseline until End of Study (up to Week 60) ]Rescue therapy consisted of IVIg or PEX. Study participants who experienced disease worsening (eg, an increase of 2 points on the MG-ADL or 3 points on the QMG scale between 2 consecutive visits) may be considered for rescue therapy at the discretion of the Investigator.

| Plan to Share IPD: | Yes |
| Plan Description: | Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available. |
