Primary Outcome Measures :
  1. Change from Baseline to Visit 10 in Myasthenia Gravis-Activities of Daily Living (MG-ADL) score [ Time Frame: Baseline and Visit 10 (Day 43) ]
    The total MG-ADL score is obtained by summing the responses to each individual item (8 items; Grades: 0, 1, 2, 3). The score ranges from 0 to 24, with a higher score indicating more disability.


Secondary Outcome Measures :
  1. Percentage of participants achieving Myasthenia Gravis-Activities of Daily Living (MG-ADL) response at Visit 10 [ Time Frame: Visit 10 (Day 43) ]
  2. Change from Baseline to Visit 10 in Myasthenia Gravis-Composite score [ Time Frame: Baseline and Visit 10 (Day 43) ]
    The total Myasthenia Gravis(MG)-composite score is obtained by summing the responses to each individual item (10 items; Grade:0-9 depending on item). The score ranges from 0 to 50, with lower scores indicating lower disease activity.

  3. Change from Baseline to Visit 10 in Quantitative Myasthenia Gravis (QMG) score [ Time Frame: Baseline and Visit 10 (Day 43) ]
    The total QMG score is obtained by summing the responses to each individual item (13 items; Responses: None=0, Mild=1, Moderate=2, Severe=3). The score ranges from 0 to 39, with lower scores indicating lower disease activity.

  4. Change from Baseline to Visit 10 in the Myasthenia Gravis (MG) Symptoms Patient Reported Outcome (PRO) 'Fatigability' score [ Time Frame: Baseline and Visit 10 (Day 43) ]

    The MG symptoms PRO instrument consists of 42 items across 5 scales: ocular symptoms (items 1-5); bulbar symptoms (items 6-15); respiratory symptoms (items 16-18); physical fatigue (items 19-33) and muscle weakness fatigability (items 34-42).

    The study participant will be asked to choose the response option that best describes the severity of ocular, bulbar, and respiratory symptoms over the past 7 days using a 4-point Likert scale ("none" to "severe") and how frequently they experience physical fatigue and muscle weakness fatigability over the past 7 days using a 5-point Likert scale ("none of the time" to "all of the time"), respectively.


  5. Change from Baseline to Visit 10 in the Myasthenia Gravis (MG) Symptoms Patient Reported Outcome (PRO) 'Physical Fatigue, Limb and Axial Weakness' score [ Time Frame: Baseline and Visit 10 (Day 43) ]

    The MG symptoms PRO instrument consists of 42 items across 5 scales: ocular symptoms (items 1-5); bulbar symptoms (items 6-15); respiratory symptoms (items 16-18); physical fatigue (items 19-33) and muscle weakness fatigability (items 34-42).

    The study participant will be asked to choose the response option that best describes the severity of ocular, bulbar, and respiratory symptoms over the past 7 days using a 4-point Likert scale ("none" to "severe") and how frequently they experience physical fatigue and muscle weakness fatigability over the past 7 days using a 5-point Likert scale ("none of the time" to "all of the time"), respectively.


  6. Change from Baseline to Visit 10 in the Myasthenia Gravis (MG) Symptoms Patient Reported Outcome (PRO) 'Bulbar' score [ Time Frame: Baseline and Visit 10 (Day 43) ]

    The MG symptoms PRO instrument consists of 42 items across 5 scales: ocular symptoms (items 1-5); bulbar symptoms (items 6-15); respiratory symptoms (items 16-18); physical fatigue (items 19-33) and muscle weakness fatigability (items 34-42).

    The study participant will be asked to choose the response option that best describes the severity of ocular, bulbar, and respiratory symptoms over the past 7 days using a 4-point Likert scale ("none" to "severe") and how frequently they experience physical fatigue and muscle weakness fatigability over the past 7 days using a 5-point Likert scale ("none of the time" to "all of the time"), respectively.


  7. Occurrence of treatment-emergent adverse events (TEAEs) [ Time Frame: From Baseline until End of Study Visit (up to Week 14) ]

    An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

    A Treatment emergent adverse event (TEAE) is defined as any event that was not present prior to the first administration of IMP or any unresolved event already present before the first administration of IMP that worsens in intensity following exposure to treatment.


  8. Treatment-emergent adverse events (TEAEs) leading to withdrawal of investigational medicinal product (IMP) [ Time Frame: From Baseline until End of Study Visit (up to Week 14) ]

    One of the secondary outcome measures is to assess safety and tolerability of the IMP in the MG patients. This can be measured by Treatment emergent adverse events (TEAEs) leading to withdrawal of IMP.

    A TEAE is defined as any event that was not present prior to the first administration of IMP or any unresolved event already present before the first administration of IMP that worsens in intensity following exposure to treatment.
