Outcome Measures

Primary Outcomes (2)

  • Percentage of Participants With Successful Self-administration of Rozanolixizumab (With Correct Use of Syringe Driver and Manual Push, Respectively) During the Self-administration Period at Visit 13 (Week 12)

    Successful self-administration was defined by the participant (i) choosing the correct infusion site, (ii) administering SC, and (iii) delivering the intended dose.

    Week 12 (last dose of Self-administration Period 1)

  • Percentage of Participants With Successful Self-administration of Rozanolixizumab (With Correct Use of Syringe Driver and Manual Push, Respectively) During the Self-administration Period at Visit 19 (Week 18)

    Successful Self-administration was defined by the participant (i) choosing the correct infusion site, (ii) administering SC, and (iii) delivering the intended dose.

    Week 18 (last dose of Self-administration Period 2)

Secondary Outcomes (3)

  • Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) After Syringe Driver or Manual Push Self-administration From Visit 2 (Week 1) up to the End of Study Visit (Visit 21 [Week 26])

    From Week 1 up to the End of Study Visit (Week 26)

  • Percentage of Participants With Local Site Reactions 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 Week 6) and Self-administration Periods (Week 7 to Week 18)

  • Percentage of Participants With Medication Errors Associated With Adverse Reactions During the 2 Self-administration Periods of the Study

    During the Self-administration Periods (Week 7 to Week 18)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Study participant must have a documented diagnosis of generalized Myasthenia Gravis (gMG)
  • Study participant is willing to perform and capable of performing home self-administration
  • Study participant is considered by the investigator for additional rozanolixizumab treatment with the posology proposed in this study.
  • Body weight ≥35 kg
  • Study participants may be male or female

You may not qualify if:

  • 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 with a known tuberculosis (TB) infection, at high risk of acquiring TB infection, or latent tuberculosis infection (LTBI), or current or history of nontuberculous mycobacterial infection (NTMBI)
  • 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

Data Sharing

IPD Sharing
Will share

Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.
