What the trial was testing
The ADAPT enrolled 151 patients with myasthenia gravis. The study was sponsored by argenx 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
68% of patients improved on daily activities for at least four weeks after treatment.
The Lancet. Neurology · 2021 · NCT03770403
These findings — that patients saw meaningful improvement in daily activities for at least four weeks — were published in the The Lancet. Neurology and represent the headline result of the study.
Researchers tracked outcomes across 151 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
Efgartigimod is now FDA-approved for myasthenia gravis under the brand name Vyvgart. It's given as weekly infusions and can be repeated based on how you respond. Talk to your neurologist to see if this treatment is right for you, especially if you test positive for acetylcholine receptor antibodies.
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.
Open myasthenia gravis trials
A Worldwide Pregnancy Safety Study to Assess Maternal, Fetal, and Infant Outcomes Following Exposure to Efgartigimod During Pregnancy and/or Breastfeeding.
This is a multi-country, prospective safety study of pregnant women exposed to efgartigimod or efgartigimod PH20 SC any time within 25 days prior to conception or any time during pregnancy. Women exposed to efgartigimod or efgartigimod PH20 SC only during breastfeeding will also be eligible to enroll. Background rates of major congenital malformations (MCMs) will be obtained from populations within the same countries/regions as the countries/regions in which the efgartigimod or efgartigimod PH20 SC exposed pregnancies were reported.
Light vs. Moderate Intensity Exercise in Individuals With Myasthenia Gravis
The overall purpose of this pilot study is to examine the feasibility, acceptability, and tolerability of light and moderate intensity exercise in adults with MGeffect of light vs. moderate intensity exercise on health outcomes. Participants will be enrolled into the NeuroWell exercise program, which is geared toward individuals with neurological disorders or injuries and led by Certified Exercise Physiologists (CEPs) at the HealthPartners Neuroscience Center. A total of 20 people with MG will be enrolled in this study and participate in a small group exercise program 3 times a week for 12 weeks. Participants will be randomized into two exercise groups: 1) Light intensity or 2) Moderate intensity. We hypothesize that light and moderate intensity exercise will be feasible, acceptable, and tolerable in adults with MG and that individuals in the light intensity exercise group will be able to achieve the same improvement in health outcomes as the moderate intensity group.
