Exclusion Criteria:

• Study participant has a known hypersensitivity to other anti-Fc receptor (FcRn) medications, to any components of the study medication, to any of the excipients (including polysorbate 80), or has a known history of hyperprolinemia, since both polysorbate 80 and L-proline are constituents of the rozanolixizumab formulation

• Study participant has a clinically relevant active infection or a history of serious infection (resulting in hospitalization or requiring IV antibiotic treatment) within 6 weeks before the Baseline Visit

• The study participant previously participated in any rozanolixizumab MG study and met any mandatory withdrawal criteria (unless the reason is directly related to MG0020 participation) or mandatory study drug discontinuation criteria.

• Study participant has received a live vaccination within 4 weeks before starting treatment, or a Bacillus Calmette-Guérin (BCG) vaccine within 1 year before starting treatment; or intends to have a live vaccination during the course of the study or within 8 weeks following the last dose of rozanolixizumab

• Study participant with severe (defined as Grade 3 on the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale) weakness affecting oropharyngeal or respiratory muscles, or who has myasthenic crisis or impending crisis

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Successful self-administration of rozanolixizumab (with correct use of syringe driver and manual push, respectively) during the Self-administration Period at Visit 13	Successful self-administration is defined by the participant (i) choosing the correct infusion site, (ii) administering subcutaneous, and (iii) delivering the intended dose.	Visit 13 (Week 12; last dose of Self-administration Period 1)
Primary	Successful self-administration of rozanolixizumab (with correct use of syringe driver and manual push, respectively) during the Self-administration Period at Visit 19	Successful self-administration is defined by the participant (i) choosing the correct infusion site, (ii) administering subcutaneous, and (iii) delivering the intended dose.	Visit 19 (Week 18; last dose of Self-administration Period 2)
Secondary	Occurrence of Treatment-Emergent Adverse Events (TEAEs) after syringe driver or manual push self-administration from Visit 2 up to the End of Study Visit	An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.	From Visit 2 (Week 1) up to the End of Study Visit (Visit 21 [Week 26])
Secondary	Occurrence of local site reactions up to 24 hours after each administration during the Training Period and Self-administration Periods	Local site reaction Adverse Events (AEs) will be considered treatment-emergent up to 24 hours after each administration during the Training Period and Self-administration Periods.	Up to 24 hours after each administration during the Training Period (Baseline to Visit 7 [Week 6] and Self-administration Periods (Visit 8 [Week 7] to Visit 19 [Week 18])
Secondary	Occurrence of medication errors associated with adverse reactions during the 2 Self-administration Periods of the study	Medication errors are defined as an unintended failure in the drug treatment process that leads to, or has the potential to lead to, harm to the study participant. Medication Errors associated with adverse reactions during the 2 Self-administration Periods will be measured.	During the Self-administration Periods (Visit 8 [Week 7] to Visit 19 [Week 18])
