What the trial was testing
The MYCARING enrolled 165 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 on rozanolixizumab improved their daily activities score by over 3 points more than placebo.
The Lancet. Neurology · 2023 · NCT04650854
These findings — that daily activities improved significantly more with the drug than without it — were published in the The Lancet. Neurology and represent the headline result of the study.
Researchers tracked outcomes across 165 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 FDA-approved in 2023 for myasthenia gravis under the brand name Rystiggo. It's given as a weekly injection for six weeks and works by blocking a receptor that contributes to the disease. If you have myasthenia gravis that isn't well controlled, ask your doctor if this treatment might be right for you.
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.

Comparative Efficacy of Nipocalimab and Efgartigimod in Participants With Generalized Myasthenia Gravis
The purpose of this study is to assess how well nipocalimab works when compared to efgartigimod in participants with generalized myasthenia gravis (a condition in which body's immune system mistakenly attacks and damages the connection between nerves and muscles causing muscle weakness).
Rare Disease Patient Registry & Natural History Study - Coordination of Rare Diseases at Sanford
CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
