Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of treatment-emergent adverse events (TEAEs)	A treatment-emergent adverse event is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study medication, whether or not considered related to the study medication.	From Baseline (Day 1) to Safety Follow-Up Visit (up to 36 months)
Secondary	Change from Baseline to Week 12 in the Myasthenia Gravis-Activities of Daily Living (MG-ADL) Score	The MG-ADL profile provides an assessment of MG symptom severity and measures 8 items on a 0-3 scale, with 0 being the least severe. The total sum of the 8 items represents the ADL score. The ADL score can range from 0 (least severe) to 24 (most severe).	From Baseline (Day 1) to Week 12
Secondary	Change from Baseline to Week 12 in the the Quantitative Myasthenia Gravis (QMG) Score	The QMG test is a standardized quantitative strength scoring system and measures 13 items on a 0-3 scale, with 0 being the least severe. The total sum of the 13 items represents the QMG score. The QMG score can range from 0 (least severe) to 39 (most severe).	From Baseline (Day 1) to Week 12
Secondary	Change from Baseline to Week 12 in the Myasthenia Gravis Composite (MGC) Score	The MGC is a 10-item scale that has been used to measure the clinical status of patients with Myasthenia Gravis (MG) in order to evaluate treatment response. The MGC has 4-point Likerttype Scale response options ranging from 0 to 2, 3, 4, 5, 6 or 9 according to the item (weighted response options). The total score is the sum of all items (range 0-50) where higher scores indicate more severe impairment due to the disease.	From Baseline (Day 1) to Week 12
Secondary	Change from Baseline to Week 12 in the Myasthenia Gravis - Quality of Life revised (MG-QOL15r) Score	The MG-QOL15r is a 15-item survey that was designed to assess quality of life in patients with MG. The MG-QoL has 3-point Likert Scale response options ranging from 0 to 2. The MGQoL15r score can range from 0 to 30, where higher scores indicate more severe impact of the disease on aspects of the patient's life.	From Baseline (Day 1) to Week 12
