    • Documented positive ice test (Ptosis recovers with the ice test [applied 2 minutes (min) to the ptotic lid] with >2mm improvement)
    • History of positive edrophonium chloride (Tensilon) test (or equivalent tests used to establish oMG diagnostic as per current practice)
    • Demonstrated objective improvement in oMG signs with acetylcholinesterase inhibitor (AChEIs), plasma exchange (PLEX), intravenous immunoglobulin (IVIg), subcutaneous immunoglobulin (SCIg) or corticosteroids (CSs)
  • Participant has an Myasthenia Gravis Impairment Index (MGII) ocular score (Patient-Reported Outcome (PRO) part) ≥6 with at least 2 ocular items with a score of ≥2 at both Screening and Baseline visits.

  • Participant reported ocular symptom(s) onset <3 years before Screening or ≥3 years provided they have demonstrated response (ie, improvement in ptosis or diploplia) to treatment (IVIg, PLEX, SCIg, pyridostigmine, and/or CSs) in the past year.

  • Participant has no pupillary abnormality except those resulting from prior localized eye disease or surgical intervention.

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.

Åtgärdsbeskrivning
Tidsram
Change from Baseline at Day 43 in (Myasthenia Gravis Impairment Index) MGII ocular score (Patient-Reported Outcome (PRO) part)
Tidsram: 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
Tidsram: 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
Tidsram: 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
Tidsram: 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.

At Day 43
Change from Baseline at Day 43 in Myasthenia Gravis Impairment Index (MGII) ocular score (Physical Examination part)
Tidsram: 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.

At Day 43
Incidence of treatment-emergent adverse events (TEAEs)
Tidsram: Up to Week 13

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 Week 13
Incidence of treatment-emergent serious adverse events (TESAEs)
Tidsram: Up to Week 13

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 Week 13
Incidence of TEAEs leading to permanent withdrawal of study treatment
Tidsram: Up to Week 13

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.

IPD-planbeskrivning

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.
