Intervenção / Tratamento |
|---|---|
|
Experimental: rozanolixizumab
Study participants will receive pre-defined doses of rozanolixizumab. Each treatment cycle in each Treatment Period (TP) consists of 6 subcutaneous (sc) administrations of rozanolixizumab at 1-week intervals. Each Treatment Period will be initiated upon the discretion of the Investigator based on the medical needs of the study-participant. |

O que o estudo está medindo?
Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Occurrence of serious Treatment-Emergent Adverse Events (TEAEs) up to the End of Study (EOS) Visit
Prazo: From Baseline up to the EOS Visit (up to 52 weeks)
|
Serious TEAEs are any untoward medical incidence in a subject during administered study treatment, whether or not these events are related to study treatment and additionally are emergent untoward medical occurrence that at any dose:
|
From Baseline up to the EOS Visit (up to 52 weeks)
|
|
Occurrence of TEAEs leading to permanent withdrawal of IMP up to the EOS Visit
Prazo: From Baseline up to the EOS Visit (up to 52 weeks)
|
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 Baseline up to the EOS Visit (up to 52 weeks)
|
|
Occurrence of Adverse Event(s) of Special Monitoring (AESM) up to the EOS Visit
Prazo: From Baseline up to the EOS Visit (up to 52 weeks)
|
AESMs are: Severe and/or serious headache, suspected aseptic meningitis, severe Gastrointestinal (GI) disorders, and opportunistic infection. |
From Baseline up to the EOS Visit (up to 52 weeks)
|
Medidas de resultados secundários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Percent change in total Immunoglobulin G (IgG) from Baseline to the end of Week 6 of each Treatment Period (TP)
Prazo: From Baseline to the end of Week 6 of each TP (up to 52 weeks)
|
Plasma concentration analyses of total IgG will be done for all study participants on an ongoing basis to the end of Week 6 of each TP. |
From Baseline to the end of Week 6 of each TP (up to 52 weeks)
|
|
Absolute change in total IgG from Baseline to the end of Week 6 of each TP
Prazo: From Baseline to the end of Week 6 of each TP (up to 52 weeks)
|
Plasma concentration analyses of total IgG will be done for all study participants on an ongoing basis to the end of Week 6 of each TP. |
From Baseline to the end of Week 6 of each TP (up to 52 weeks)
|
|
Change from Baseline in Myasthenia Gravis-Activities of Daily Living (MG ADL) total score at the end of Week 6 of each TP
Prazo: From Baseline to the end of Week 6 of each TP (up to 52 weeks)
|
The MG-ADL score is an 8-item patient-reported outcome (PRO) instrument. The MG-ADL targets symptoms and disability across ocular, bulbar, respiratory, and axial symptoms. The item responses are scored from 0 to 3, and the total score of MG-ADL is the sum of the 8 items and ranges from 0 to 24, with a higher score indicating more disability. |
From Baseline to the end of Week 6 of each TP (up to 52 weeks)
|
|
Change from Baseline in Quantitative Myasthenia Gravis (QMG) total score at the end of Week 6 of each TP
Prazo: From Baseline to the end of Week 6 of each TP (up to 52 weeks)
|
QMG score is a standardized and validated quantitative strength scoring system that was developed specifically for MG. The QMG total score is obtained by summing the responses to each individual item (13 items; Responses: None=0, Mild=1, Moderate=2, Severe=3). The score ranges from 0 to 39, with lower scores indicating lower disease activity. |
From Baseline to the end of Week 6 of each TP (up to 52 weeks)

Descrição do plano 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 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.
