A female participant is eligible to participate if she is not, not breastfeeding (including pumping breastmilk to feed a child), and at least 1 of the following conditions applies:
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

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. A Symptom-driven Cycle will be initiated based on disease worsening and participants will receive rozanolixizumab based on investigator's medical judgement.
Drug: Rozanolixizumab
Rozanolixizumab will be administered by subcutaneous infusion.

Incidence of treatment-emergent adverse events (TEAEs)
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.
Time frame: Up to 2 years
Incidence of treatment-emergent serious adverse events (TESAEs)
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.
Time frame: Up to 2 years
Incidence of TEAEs leading to permanent withdrawal of study treatment
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.
Time frame: Up to 2 years
Change from Baseline at Day 43 in (Myasthenia Gravis Impairment Index) MGII ocular score (Patient-Reported Outcome part)
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".
Time frame: 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
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.
Time frame: 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
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)
Time frame: 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
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).
Time frame: 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
MGFA Clinical Classification is a 5-stage classification (I to V), with a higher class indicating more severe disease.
Time frame: Up to 2 years
Change from Baseline in MGII total and generalized score over time
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".
Time frame: Up to 2 years
Change from Baseline in MG-ADL total score over time
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.
Time frame: Up to 2 years
Plan to share: Yes — 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.
