ListOutcomeTime frameDescription
PrimaryNumber of Patients With Treatment Emergent Adverse Events (TEAES) and Treatment Emergent Serious Adverse Events (SAEs)Day 1 to Day 78
TEAEs were defined as AEs that first occurred or worsened in severity after the first administration of the treatment. A treatment emergent SAE was any untoward medical occurrence that resulted in death; was life-threatening; required inpatient hospitalization or prolongation of existing hospitalization;resulted in persistent or significant disability or incapacity; was a congenital abnormality or birth defect; or other medically significant events. All TEAEs observed were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.03 with descriptions of severity for each AE based on the following general guideline: Grade 1= mild; Grade 2 = moderate; Grade 3 = severe or medically significant but not immediately life-threatening; Grade 4 = life-threatening consequences; Grade 5 = death related to AE.
PrimaryMean Change From Baseline in Vital Signs: Blood PressureBaseline and Days 8,15, 22, 29, 36, 43, 50, 64 and 78
The patients' diastolic and systolic blood pressure were measured pre-dose on dosing days 1,8,15 and 22 and also during the follow up period. The mean change from baseline at each time point is presented. Baseline is defined as the last non-missing value before first dose of study medication.
PrimaryMean Change From Baseline in Vital Signs: Heart RateBaseline and Days 8,15, 22, 29, 36, 43, 50, 64 and 78
The patients' heart rate was measured pre-dose on dosing days 1,8,15 and 22 and also during the follow up period. The mean change from baseline at each time point is presented. Baseline is defined as the last non-missing value before first dose of study medication.
PrimaryMean Change From Baseline in Vital Signs: TemperatureBaseline and Days 8,15, 22, 29, 36, 43, 50, 64 and 78
The patients' temperature was measured pre-dose on dosing days 1,8,15 and 22 and also during the follow up period. The mean change from baseline at each time point is presented. Baseline is defined as the last non-missing value before first dose of study medication.
PrimaryMean Change From Baseline in Vital Signs: WeightBaseline and Days 8,15, 22, 29, 36, 43, 50, 64 and 78
The patients' weight as measured pre-dose on dosing days 1,8,15 and 22 and also during the follow up period. The mean change from baseline at each time point is presented. Baseline is defined as the last non-missing value before first dose of study medication.
PrimaryNumber of Patients With Abnormal Clinically Relevant Findings in Electrocardiogram (ECG) ParametersDay 1 to Day 78
ECG parameters of heart rate, PR, QT, and QRS interval were read locally and performed pre-dose on dosing days 1,8,15 and 22 and on the last follow up visit on Day 78. Any patients recording abnormal clinically relevant findings during the study are presented.
PrimaryNumber of Patients With Abnormal Clinical Laboratory Findings Reported as TEAEsDay 1 to Day 78
Sampling for clinical laboratory tests including hematology, clinical chemistry, and urinalysiswas performed pre-dose on dosing Days 1, 8, 15 and 22 and throughout the follow up period. Patients fasted for at least 8 hours prior to this sampling. Abnormal laboratory values, or test results were not reported as TEAEs unless they were associated with clinical signs and symptoms that were considered clinically relevant, required therapy or led to treatment discontinuation. Patients reporting TEAEs in any of the laboratory parameters during the study are presented.
SecondaryMean Change From Baseline in Myasthenia Gravis-Activities of Daily Living (MG-ADL) ScoreBaseline and Days 8,15, 22, 29, 36, 43, 50, 64 and 78
The MG-ADL is an 8-item patient-reported scale to assess MG symptoms and their effects on daily activities. It evaluates the capacity to perform different activities of daily living such as talking, chewing, swallowing, breathing, brushing the teeth/combing the hair, or arising from the chair and it also assesses double vision and eyelid droop. The 8 items are rated from 0 to 3 and the total score could point from 0 to 24; with higher scores indicating more impairment. The mean change in MG-ADL score from baseline is presented for each timepoint with a clinically meaningful improvement defined as a drop of at least 2 points as compared with baseline.
SecondaryMean Change From Baseline in QMG ScoreBaseline and Days 8,15, 22, 29, 36, 43, 50, 64 and 78
The QMG quantifies disease severity based on impairments of body functions and structures as defined by the International Classification of Disability and Health. The QMG consists of 13 items that includes ocular, bulbar, and limb function. Out of the 13 items, 6 are timed tests of endurance measured in seconds. Each item has a possible score from 0-3. The score range is 0-39, where higher scores indicate more severe impairments. The mean change in QMG score from baseline is presented with a clinically meaningful improvement defined as a drop of at least 3 points as compared with baseline.
SecondaryMean Change From Baseline in MGC ScoreBaseline and Days 8,15, 22, 29, 36, 43, 50, 64 and 78
The MGC has 10 items combining physician examination and patient-reported outcomes. The 2 ocular items are derived from QMG. It has 3 items on muscle strength (deltoids, hip flexors, and neck flexors or extensors) and 4 items on bulbar function (swallowing, chewing, breathing, and speech functions), based on the clinical history. Each item is scored on an ordinal scale with 4 possible categories, but the items are weighted, whereby bulbar impairments weigh more than ocular ones. The impairments that were examined by the Investigator included ptosis or upward gaze, double vision, eye closure, neck flexion, shoulder abduction, and hip flexion. The patient-reported outcomes under MGC are talking, chewing, swallowing, and breathing. The maximum possible score is 50 (range from 0-50), with higher scores reflecting more severe impairments. The mean change in MGC score from baseline is presented.
