    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1.Have the ability to understand the requirements of the study, provide written informed consent (including consent for the use and disclosure of research-related health information), and comply with the study protocol procedures (including required study visits).
    2.Male or female patients aged ≥18 years.
    3.Diagnosis of autoimmune MG with generalized muscle weakness meeting the clinical criteria for diagnosis of MG as defined by the Myasthenia Gravis Foundation of America (MGFA) Clinical Classification Class II, III or IVa, and likely not in need of a respirator for the duration of the study as judged by the Investigator.
    The confirmation of the diagnosis should be documented and supported by:
    • Positive serologic test for anti-AChR antibodies before Screening and
    • at least 1 of the following 3 tests:
    (i) History of abnormal neuromuscular transmission test demonstrated by single-fiber electromyography or repetitive nerve stimulation or
    (ii) History of positive edrophonium chloride test, or
    (iii) Patient has demonstrated improvement in MG signs on oral cholinesterase inhibitors as assessed by the treating physician.
    4.A total score of ≥5 on the MG ADL at Screening and Baseline with more than 50% of this score attributed to non-ocular items.
    5.Patients are required to be on a stable dose of their MG treatment prior to randomization. For patients receiving AZA, other NSIDs, steroids, and/or cholinesterase inhibitors as concomitant medications the following conditions will apply:
    •AZA: treatment initiated at least 12 months ago and no dose changes in the last 6 months before Screening.
    •Other NSIDs (e.g., methotrexate, cyclosporine, tacrolimus, mycophenolate mofetil, and cyclophosphamide): treatment initiated at least 6 months ago and no dose changes in the last 3 months before Screening.
    •Steroids: treatment initiated at least 3 months prior to and no dose changes in the last month before Screening.
    •Cholinesterase inhibitors: to be on a stable dose for >2 weeks before Screening.
    Note: cholinesterase inhibitors must be held for at least 12 hours consistent with the revised manual for the QMG test as recommended by the Myasthenia Gravis Foundation of America Inc [MGFA]1, before the MGQoL15r, MG ADL, QMG, and MGC assessments.
    6.Females of childbearing potential must have a negative serum pregnancy test at Screening and a negative urine pregnancy test at Visit 1 prior to administration of IMP. Female of childbearing potential are defined as all female participants unless they are postmenopausal (defined by continuous amenorrhea) for at least 2 years with a Follicle stimulating hormone (FSH) >40 IU/L or are surgically sterile (i.e., who had a hysterectomy, bilateral oophorectomy, or have current documented tubal ligation or any other permanent female sterilization procedure). Determination of FSH levels can be used to confirm postmenopausal status in amenorrheic patients not on hormonal replacement therapy if the test result is within the postmenopausal range per the central laboratory.
    7.Female participants of childbearing potential must agree to use a highly effective method of contraception (i.e., pregnancy rate of less than 1% per year) during the study and for 90 days after the discontinuation of the IMP. Adequate contraceptive methods include combined hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), intrauterine devices (IUDs), intrauterine hormone-releasing system (IUS), true sexual abstinence (when this is in line with the preferred and usual lifestyle of the participant), bilateral tubal occlusion, or a female participant who is not of childbearing potential. Female participants and female partners of male study participants using a hormonal contraceptive must also use a barrier method (i.e., condom or occlusive cap [diaphragm or cervical/vault caps]) and should have been stable on their hormonal contraceptive treatment for at least 4 weeks before Screening.
    8.Sterilized male patients who have had vasectomy a year back with documented aspermia post procedure can be included. In addition, male patients must be advised not to donate sperm during this period from signing of Informed Consent Form (ICF), throughout the duration of the study, and for 90 days after the last administration of IMP. Non-sterilized male patients who are sexually active with a female partner of childbearing potential must use effective method of double barrier contraception (e.g., condom with spermicidal cream or jelly, 1 hormonal plus 1 barrier method or 2 simultaneous barrier methods). Male patients practicing true sexual abstinence (when this is in line with the preferred and usual lifestyle of the participant) can be included.
    1.Comprender los requisitos del estudio, proporcionar consentimiento informado por escrito y someterse a los procedimientos del protocolo del estudio (incluidas las visitas del estudio requeridas).
