The dose of steroid should be stepped down by 10 mg qod (every other day) for every 2 weeks until the dose achieves 40 mg qod. After that, the dose should be stepped down by 5 mg qod for every month.\n * When disease progresses and is no longer maintaining minimal manifestation, the dose of steroid will be stepped up by 10 mg qod for every 2 weeks until achieve clinical stable remission. The taper rule of steroid could start again 1 month after stabilization.\n * Every patient will be treated for 1 year. If the patient could not achieve MM within 1 year, the blind of individual patient will be opened and the patients will be crossed over to another medical treatment. The efficacy and safety of second medication will be observed openly until the end of study.\n * When the muscle weakness worsens under established study schedule, plasmapheresis could be conducted to improve the condition rapidly.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Male or female age between 20-70 (including 20 and 70 years old).\n* Osserman II and III Myasthenia Gravis.\n* Positive serum anti-acetylcholine receptor antibodies.\n* Poor control of disease with daily dose of prednisone ≥ 30 mg or 0.5 mg/kg at 3 months before enrollment.\n* Without immunosuppressive therapy other than steroid.\n\nExclusion Criteria:\n\n* Ocular MG or minimal clinical syndrome that would not require the therapy of steroids.\n* Negative serum anti-acetylcholine receptor antibodies.\n* Use immunosuppressants other than steroids in the preceding year.\n* Previous use other investigational medication within 3 months or current participate other clinical study.\n* Poor renal function: serum creatinine \\> 3.0 mg/dl or estimated creatinine clearance \\< 30 ml/min\n* Females who are pregnancy or breast-feeding.\n* Recent history, within 5 years, of malignancy\n* Unwilling or unable to participate the necessary continuous visits and examinations.'}, 'identificationModule': {'nctId': 'NCT00997412', 'acronym': 'Myfortic', 'briefTitle': 'Trial of Mycophenolic Acid Versus Azathioprine in the Treatment of Corticosteroid-refractory Myasthenia Gravis', 'organization': {'class': 'INDUSTRY', 'fullName': 'Qualitix Clinical Research Co., Ltd.'}, 'officialTitle': 'Randomized, Double-blind, Double-dummy Trial of Mycophenolic Acid Versus Azathioprine in the Treatment of Corticosteroid-refractory Myasthenia Gravis', 'orgStudyIdInfo': {'id': 'CERL080ATW07T'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'MA', 'description': 'MA group: 1 tablet AZA placebo and 4 tablets MA (180mg/tab,720 mg/day) twice daily', 'interventionNames': ['Drug: Mycophenolic acid']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'AZA', 'description': 'AZA group: 1 tablet AZA (50mg/tab) and 4 tablets MA placebo twice daily', 'interventionNames': ['Drug: AZA']}], 'interventions': [{'name': 'Mycophenolic acid', 'type': 'DRUG', 'description': '180 mg/tablet, 4 tablets twice daily', 'armGroupLabels': ['MA']}, {'name': 'AZA', 'type': 'DRUG', 'description': '1 tablet AZA (50 mg/tab) and 4 tablets MA placebo twice daily', 'armGroupLabels': ['AZA']}]}, 'contactsLocationsModule': {'overallOfficials': [{'name': 'Jiann-Horng Yeh, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Shin Kong Wu Ho-Su Memorial Hospital'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Qualitix Clinical Research Co., Ltd.', 'class': 'INDUSTRY'}, 'responsibleParty': {'oldNameTitle': 'Jiann-Horng Yeh / M.D.', 'oldOrganization': 'Shin Kong Wu Ho-Su Memorial Hospital'}}}}
