What the trial was testing
The MYCARING enrolled 71 patients with myasthenia gravis. The study was sponsored by UCB Biopharma SRL and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Patients had a 3.4-point improvement in daily living scores versus 0.8 with placebo.

These findings — that weekly rozanolixizumab reduced myasthenia gravis symptoms much more than placebo — were published in the The Lancet. Neurology and represent the headline result of the study.
Researchers tracked outcomes across 71 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with myasthenia gravis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Rozanolixizumab was approved by the FDA in 2023 for adults with myasthenia gravis. It's given as a weekly injection under the skin for 6 weeks. Talk to your neurologist to see if this treatment is right for you, especially if current therapies aren't controlling your symptoms well enough.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Evaluating the Pharmacokinetics, Pharmacodynamics, and Safety of Efgartigimod Administered Intravenously in Children With Generalized Myasthenia Gravis
The purpose of this trial is to investigate the PK, PD, safety, and activity of efgartigimod IV in children and adolescents aged from 2 to less than 18 years of age with gMG. Trial details include: * The maximum trial duration for each individual participant will be approximately 28 weeks * The treatment duration will be 8 weeks for the dose-confirmatory part (Part A) and 18 weeks for the treatment response-confirmatory part (Part B)
A Non-interventional, Post-authorisation Safety Study of Patients Treated With Efgartigimod Alfa
This is a non-interventional, prospective, post authorization safety study. Patients with gMG who are expected to start treatment with efgartigimod at enrolment or are within their first cycle of efgartigimod at enrolment will be eligible to enroll into the efgartigimod cohort. Patients with gMG who have not been exposed to efgartigimod and for whom it is not planned to start treatment with efgartigimod at enrolment will be eligible to enroll into the non-efgartigimod cohort.
