This study is designed to address the evidence gaps in a real-world setting and help patients with MG choose treatments that are best suited to them. It is a prospective, multicenter observational cohort study of comparative effectiveness of MG treatments, with a patient-centered primary outcome measure, to guide clinicians, patients and payers regarding the choice of treatment options for this chronic and serious disease.
Primary: To compare the effectiveness of azathioprine (AZT) and mycophenolate mofetil (MMF).
Secondary: To compare the outcomes in patients receiving an adequate dose and duration of AZT or MMF over the 2 year study period, vs. patients not receiving adequate doses and duration of these agents

Patients with MG who are receiving azathioprine as part of routine clinical care

Other Name: Cellcept
- Change in Patient-Reported Myasthenia Gravis Quality of Life, 15, revised ( MG-QOL15r) [ Time Frame: Baseline, 24 months ]Measures MG symptoms, physical, social and emotional functioning related to MG, with 15 items, 3 response option, 0-2 for each item, Total score range 0-30, higher scores indicating worse function
- Change in composite outcome of clinical improvement and adverse effects [ Time Frame: Baseline, 24 months ]
measured by a composite of clinical improvement and adverse effects of treatments. Clinical improvement: achievement of MGFA Post-Intervention Status (PIS) Minimal Manifestation Status (MM) or better, defined below.
Adverse effects end point: no more than Grade 1 CTCAE (Common Terminology Criteria for Adverse Events) medication side-effects, defined below.
MGFA PIS- MM: the patient has no symptoms or functional limitations from MG but has some weakness on examination of some muscles
CTCAE: list of adverse event (AE) terms commonly encountered in oncology but is useful to monitor the side effects of any intervention Each AE term is defined and graded on a 1 to 5 scale indicating the severity of the AE, 1 representing the mildest side effect and 5 representing death Grade 1 CTCAE side-effects: "asymptomatic or only mild symptoms; intervention not indicated"
- Change in Myasthenia gravis composite (MGC) scores [ Time Frame: Baseline, 24 months ]
10 item scale of patient-reported functions and clinician-reported examination findings.
Scores range from 0-50 (0- normal and 50- most severe)
- Change in Myasthenia Gravis Activities of Daily Living Scale (MG-ADL) [ Time Frame: Baseline, 24 months ]Patient-reported 8- item questionnaire evaluating commonly reported symptoms in MG on a 4 response scale from 0-3 (0 - normal, 3- highest disability) Range 0-24, higher score is worse
- Change in Myasthenia Gravis Manual Muscle Test scores (MG-MMT) [ Time Frame: Baseline, 24 months ]Clinician-assessed scale of 18 muscle functions commonly affected by MG, each graded from 0 (normal) to 4 (paralyzed/unable to perform), Range 0-120, higher score reflects worse function
- Change in Visual Analogue Scale (VAS) for Disease Severity [ Time Frame: Baseline, 24 months ]Patient perception of disease severity measured in millimeters on a 100 mm line. Higher number indicates more severe disease
- Change in Visual Analogue Scale (VAS) for Treatment Side effects [ Time Frame: Baseline, 24 month ]patient perception of side effects of treatment measured in millimeters on a 100 mm line. Higher number indicates worse side effects
- Change in number of hospitalizations for MG [ Time Frame: Baseline, 24 month ]counts of hospitalizations for MG- higher count is worse
