Nipocalimab vs Efgartigimod for Myasthenia Gravis
(EPIC Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial compares two treatments, nipocalimab (an experimental treatment) and efgartigimod (a new potential drug), to determine which is more effective for people with generalized myasthenia gravis. Myasthenia gravis occurs when the immune system attacks the connection between nerves and muscles, causing muscle weakness. Participants will receive either nipocalimab every two weeks or efgartigimod weekly, with some possibly switching treatments during the trial. Ideal candidates are those diagnosed with generalized myasthenia gravis who experience muscle weakness and have not responded well to their current treatment. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potential new treatment option.
Do I need to stop my current medications for the trial?
The trial does not clearly specify if you need to stop your current medications. However, if you are in Arms 1 or 2, you should not have received certain treatments for myasthenia gravis recently. If you are in Arm 3, you can continue taking efgartigimod.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that nipocalimab is generally safe and well-tolerated for people with generalized myasthenia gravis. In previous studies, patients experienced symptom improvements with only a few side effects, which were usually mild and temporary.
For efgartigimod, current data indicate it is an important treatment option for myasthenia gravis. However, some reports suggest a potential risk of infections. These infections occurred in some patients but were neither common nor severe.
Both nipocalimab and efgartigimod have shown promise in helping people with myasthenia gravis, with manageable safety profiles. This suggests they are likely safe for most people, but monitoring for any side effects during treatment remains important.12345Why are researchers excited about this trial's treatments?
Researchers are excited about nipocalimab and efgartigimod for treating Myasthenia Gravis because they offer unique approaches compared to traditional therapies. Unlike standard treatments like cholinesterase inhibitors and immunosuppressants, nipocalimab works by targeting the neonatal Fc receptor (FcRn), which plays a role in the immune system's regulation of antibodies. Efgartigimod also targets FcRn, but it acts differently by blocking the receptor to reduce pathogenic antibodies. Both treatments have the potential to provide more targeted immunotherapy, which could lead to improved effectiveness with fewer side effects, offering new hope for those with Myasthenia Gravis.
What evidence suggests that this trial's treatments could be effective for myasthenia gravis?
This trial will compare Nipocalimab and Efgartigimod for treating generalized myasthenia gravis (gMG). Studies have shown that Nipocalimab, which participants in this trial may receive, can lead to lasting improvement in gMG symptoms by reducing harmful antibodies for up to 18 months. This reduction may provide patients with long-term relief from muscle weakness. Evidence suggests that Nipocalimab is generally well-tolerated by people with gMG.
Meanwhile, research has shown that Efgartigimod significantly improves muscle function in gMG patients. In one study, 68% of patients experienced better Myasthenia Gravis symptoms after treatment. Efgartigimod appears to help many people by lowering specific antibodies that cause muscle weakness. Both treatments have shown promise in improving life for those with gMG.46789Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for people with generalized myasthenia gravis, a condition where the immune system weakens muscles. Participants must have been diagnosed according to specific criteria and have a certain level of daily living impairment. They should be medically stable and not responding well to current treatments or unable to take them due to side effects.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive either nipocalimab or efgartigimod intravenously. Nipocalimab is administered at a loading dose on Day 1 followed by maintenance dosing every 2 weeks until Week 12. Efgartigimod is administered once a week for 4 weeks starting from Day 1.
Treatment Switch
Participants previously treated with efgartigimod may switch to nipocalimab, receiving a loading dose on Switch Day 1 followed by maintenance dosing every 2 weeks until Switch Week 12.
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- Efgartigimod
- Nipocalimab
Trial Overview
The study compares two drugs, Nipocalimab and Efgartigimod, for treating muscle weakness in myasthenia gravis patients. It aims to determine which drug works better at improving symptoms.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Active Control
Participants previously treated with efgartigimod, who are directly enrolled in this arm, and eligible participants switching from Arm 2 will receive nipocalimab IV at a loading dose on Switch Day 1 followed by maintenance dosing q2w until Switch Week 12.
Participants will receive nipocalimab intravenously (IV), at a loading dose on Day 1 followed by maintenance dosing once every 2 weeks (q2w) until Week 12.
Participants will receive efgartigimod IV, once a week for 4 weeks starting from Day 1. Eligible participants will be given the option to switch to Arm 3 between Week 4 and Week 12.
