Myasthenia Gravis Explained

Myasthenia gravis is a long-term rager where your muscles and nerves can't seem to get their act together. It's caused by an immune system gone wild, attacking its own cells like a bull in a china shop.

Symptoms of Myasthenia Gravis
Symptoms of myasthenia gravis vary from person to person. They're often more prominent during periods of high exertion and tend to disappear with rest. Watch out for:
40 kg to less than 60 kg (approximately 88 lb to less than 132 lb)

Who Ultomiris is for
3,000 mg every 8 weeks
Ultomiris is intended for grown-ups with generalized myasthenia gravis (gMG) who test positive for anti-acetylcholine receptor (AChR) antibodies.
- "Generalized" means the craziness affects several muscle groups. That's different from ocular myasthenia gravis, which only pucks the eye muscles.
- "Anti-acetylcholine receptor (AChR) antibody-positive" means your immune system makes antibodies that block acetylcholine receptors. Acetylcholine is the henchman that sends messages telling muscles to contract.
60 kg to less than 100 kg (approximately 132 lb to less than 220 lb)
Before prescribing Ultomiris, your doctor might do a blood test to see if your gMG plays ball with anti-AChR antibodies. Your doctor can fill you in on all the deets about what Ultomiris could do for your unique form of myasthenia gravis.

How Ultomiris Treats Myasthenia Gravis
3,300 mg every 8 weeks
Why does Ultomiris give your muscles new life? Here's the skinny:
Ultomiris works its magic at the junction where nerve cells and muscles get together, known as the neuromuscular junction (NMJ). It quietly blocks the action of a complement system protein called C5. By doing this, Ultomiris helps nerve impulses reach your muscles, reducing tiredness and muscle weakness, and boosting muscle strength.
