Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Rozanolixizumab

The study is composed of Extended Observation Period(s) and Symptom-driven Cycle(s). Based on their clinical need for treatment, study participants will be able to start the study with either an Extended Observation Period or a Symptom-driven Cycle.

Misura del risultato
Misura Descrizione
Lasso di tempo
Incidence of treatment-emergent adverse events (TEAEs)
Lasso di tempo: Up to 2 years

Treatment Emergent Adverse Events (TEAEs) are any untoward medical incidence in a participant after the administration of study treatment, whether or not these events are related to study treatment.

Up to 2 years
Incidence of treatment-emergent serious adverse events (TESAEs)
Lasso di tempo: Up to 2 years

An SAE is defined as any untoward medical occurrence that, at any dose, meets 1 or more of the criteria listed:

  • Results in death
  • Is life-threatening
  • Requires inpatient hospitalization or prolongation of existing hospitalization
  • Results in persistent or significant disability/incapacity
  • Is a congenital anomaly/birth defect
  • Other important medical events which based on medical or scientific judgement may jeopardize the patients or may require medical or surgical intervention to prevent any of the above.
Up to 2 years
Incidence of TEAEs leading to permanent withdrawal of study treatment
Lasso di tempo: Up to 2 years

Treatment Emergent Adverse Events (TEAEs) are any untoward medical incidence in a participant after the administration of study treatment, whether or not these events are related to study treatment. This measure considers any TEAE leading to permanent withdrawal from study.

Up to 2 years

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change from Baseline at Day 43 in (Myasthenia Gravis Impairment Index) MGII ocular score (Patient-Reported Outcome part)
Lasso di tempo: At Day 43 (of the first 3 Symptom-driven Cycles)

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".

At Day 43 (of the first 3 Symptom-driven Cycles)
Change from Baseline at Day 43 in Myasthenia Gravis Activities of Daily Living (MG-ADL) ocular score
Lasso di tempo: At Day 43 (of the first 3 Symptom-driven Cycles)

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. The two ocular items will be summed for the ocular score, ranging from 0 to 6.

At Day 43 (of the first 3 Symptom-driven Cycles)
Change from Baseline at Day 43 in Myasthenia Gravis Symptoms Patient-Reported Outcome (MGSPRO) ocular muscle weakness scale score
Lasso di tempo: At Day 43 (of the first 3 Symptom-driven Cycles)

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). Only the ocular muscle weakness scale will be used in this study. Ocular symptom severity is assessed over the past 7 days using a 4-point verbal rating scale (none, mild, moderate, severe)

At Day 43 (of the first 3 Symptom-driven Cycles)
Change from Baseline at Day 43 in Myasthenia Gravis Quality of Life 15-item Scale (revised version) (MG-QoL15r) total score
Lasso di tempo: At Day 43 (of the first 3 Symptom-driven Cycles)

The MG-QoL15r is a 15-item PRO measure that is designed to assess aspects of health-related quality of life related to MG. The recall period that will be used is "past 7 days". Each item has 3 response options (0-2) and the total score ranges from 0 to 30, with higher scores indicating more severe impact on health-related QoL (HRQOL).

At Day 43 (of the first 3 Symptom-driven Cycles)
Study participant who generalizes to Myasthenia Gravis Foundation of America (MGFA) class ≥2 over time
Lasso di tempo: Up to 2 years

MGFA Clinical Classification is a 5-stage classification (I to V), with a higher class indicating more severe disease.

Up to 2 years
Change from Baseline in MGII total and generalized score over time
Lasso di tempo: Up to 2 years

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".

Up to 2 years
Change from Baseline in MG-ADL total score over time
Lasso di tempo: Up to 2 years

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. The two ocular items will be summed for the ocular score, ranging from 0 to 6.

Descrizione del piano 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.
