Experimentální: Rozanolixizumab
After the Screening Period, participants will enter the study Intervention Period and will be administered study drug for up to 6 weeks. Prior to entering the Intervention Period, study participants will be randomized at a 1:1 ratio and will receive rozanolixizumab. At the End of Treatment Visit, participants will enter an Observation Period of 4 to 7 weeks with an opportunity to transition to an open-label extension study. |
Rozanolixizumab will be administered by subcutaneous infusion.

Change from Baseline at Day 43 in (Myasthenia Gravis Impairment Index) MGII ocular score (Patient-Reported Outcome (PRO) part)
Časové okno: At Day 43
|
MGII is a measure of disease severity based on the signs and symptoms of MG patients. The MGII has 22 patient-reported items and 6 examination items and scores are presented as a sum of all items for a total score but also as an ocular and generalized sub-score. The scoring range is 0 to 84, 0-23 for the ocular score, and 0-61 for the generalized score, where higher scores are indicative of more severe symptoms. The recall period is "the past week" ie, the last 7 days. |

Change from Baseline at Day 43 in Myasthenia Gravis Symptoms Patient-Reported Outcome (MGSPRO) ocular muscle weakness scale score
Časové okno: At Day 43
|
The MG symptoms PRO instrument consisted of 42 items across 5 scales: ocular muscle weakness (items 1-5); bulbar muscle weakness (items 6-15); respiratory muscle weakness (items 16-18); physical fatigue (items 19-33) and muscle weakness fatigability (items 34-42). Study participants will be asked to choose response option that best describes how frequently they experienced muscle weakness fatigability (items 34-42) over the past 7 days using a 5-point Likert scale (1="none of the time" to 5="all of the time") for each item. |
At Day 43
|
|
Change from Baseline at Day 43 in Myasthenia Gravis Quality of Life 15-item Scale (revised version) (MG-QoL15r) total score
Časové okno: At Day 43
|
The MG-QoL15r is a brief survey, completed by the study participant, that is designed to assess some aspects of "quality of life" related to MG. The recall period that will be used is "past 7 days". When completing the 15-item MG-QoL15r, MG study participant should consider only how their MG affects these items. |
At Day 43
|
|
Change from Baseline at Day 43 in Myasthenia Gravis Activities of Daily Living (MG-ADL) ocular subdomain score
Časové okno: At Day 43
|
The total MG-ADL score is obtained by summing the responses to each individual item (8 items; Grades: 0, 1, 2, 3). The score ranges from 0 to 24, with a higher score indicating more disability. A positive change indicates worsening and a negative change indicates improvement. |

Plánujete sdílet data jednotlivých účastníků (IPD)?
Popis plánu IPD
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 pre-specified 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.
