The FDA takes safety seriously, and these infections can be life-threatening. For the full scoop, make sure to read the "Before receiving Ultomiris" section.
Myasthenia gravis: The lowdown
Body weight
Got myasthenia gravis? This chronic condition results in dysfunction between muscles and nerves, leading to tired muscles and weakness. It's an autoimmune condition, which basically means your immune system is attacking your own cells.
Loading dose
Ever wondered what symptoms to look out for? They vary from person to person but usually worsen during periods of increased activity and improve with rest. The red flags include:
Maintenance dose
- drooping eyelids
- weak muscles in your limbs, neck, and eyes
- fatigue
- blurry or double vision
- difficulty chewing, swallowing, speaking, and breathing
For whom is Ultomiris prescribed?
40 kg to less than 60 kg (approximately 88 lb to less than 132 lb)
Ultomiris is prescribed to treat generalized myasthenia gravis (gMG) in adults who are positive for anti-acetylcholine receptor (AChR) antibodies.
2,400 mg
- "Generalized" means that muscle groups throughout the body are affected. gMG is different from ocular myasthenia gravis, which only affects eye muscles.
- "Anti-acetylcholine receptor (AChR) antibody-positive" means that your immune system makes antibodies that block acetylcholine receptors. Acetylcholine is a neurotransmitter that sends signals that cause muscles to contract.
3,000 mg every 8 weeks
Before prescribing Ultomiris, your doc may order a blood test to check if your gMG is AChR antibody-positive. Your doctor can provide more information on how they'll determine whether Ultomiris is suitable for your form of myasthenia gravis.
How Ultomiris treats myasthenia gravis
60 kg to less than 100 kg (approximately 132 lb to less than 220 lb)
Ever wondered how Ultomiris zaps myasthenia gravis? Well, the exact workings aren't fully understood, but it's thought to involve its ability to block the activity of a complement system protein called C5 at the neuromuscular junction (NMJ).
2,700 mg
The NMJ is where nerve cells communicate with the muscles they control. By lowering C5 activity at the NMJ, Ultomiris helps signals from nerve cells reach your muscles. This could potentially reduce fatigue and muscle weakness, improve muscle strength, and help you carry out daily activities with more ease.
3,300 mg every 8 weeks
How effectively does Ultomiris work for myasthenia gravis?
In clinical studies, Ultomiris showed improvements in the ability to carry out daily living activities in adults with generalized myasthenia gravis (gMG) who were anti-acetylcholine receptor (AChR) antibody positive.
100 kg or more (approximately 220 lb or more)
