A Tale of Ultomiris: A Possible Solution for Myasthenia Gravis?
Myasthenia Gravis Treatment with Ultomiris: Insights into its Function and Additional Details
Put on your lab coats, grab a cuppa, and get ready to dive into the world of Ultomiris! No, it's not a superhero, but this intravenous infusion could be a game-changer for those battling myasthenia gravis. This article takes an informal, straightforward look at what Ultomiris is, how it works, and its potential role in treating myasthenia gravis.
Ultomiris, scientifically known as ravulizumab-cwvz, is a biologic medication that falls under the category of complement inhibitors. Unlike your average pill, Ultomiris requires an IV infusion, administered by a healthcare professional. It's important to note that Ultomiris doesn't have a biosimilar version available at the moment.
Myasthenia gravis is a chronic autoimmune condition where dysfunctional communication between muscles and nerves makes your voluntary muscles tire quickly and weaken. Symptoms range from droopy eyelids, weak limbs, and fatigue to blurry or double vision, trouble swallowing, and even difficulty breathing. If Ultomiris seems familiar, skip to the enrichment section to find out why.
Ultomiris has a boxed warning, the most serious warning from the Food and Drug Administration (FDA), but we'll get to that later. It's prescribed for adults with generalized myasthenia gravis (gMG), who test positive for anti-acetylcholine receptor (AChR) antibodies.

Now, what makes Ultomiris tick? The exact process isn't fully understood, but it's believed to involve blocking the activity of a complement system protein called C5 at the neuromuscular junction (NMJ). 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, potentially reducing fatigue and muscle weakness.
Loading dose
In clinical studies, Ultomiris proved effective in improving the ability to perform daily tasks for adults with generalized myasthenia gravis (gMG) who were AChR antibody-positive. For more details, check out the prescribing information for Ultomiris.
Maintenance dose
So, how do you get your paws on some Ultomiris? The medication comes in three strengths, with the dosage based on your body weight. Treatment typically begins with a loading dose, followed by maintenance doses, usually given every 8 weeks. Your doc will provide guidance on the best dosage for you—pregnant ladies, breastfeeding mamas, and heavy drinkers, pay heed!
Ultomiris raises the risk of serious meningococcal infections, so before you start receiving treatment, you'll need to make sure you're up-to-date with meningococcal vaccines. During treatment and for at least 8 months after your final dose, contact your doctor immediately if you experience symptoms of a meningococcal infection.

Ultomiris is only available under a risk evaluation and mitigation strategy (REMS) program. You'll need to carry the Ultomiris Patient Safety Card throughout treatment and for 8 months after your last dose. But don't worry; you can find more information about the Ultomiris REMS program on the program website or by calling 1-888-765-4747.

Now, let's deal with a few minor hiccups, shall we? Some common side effects of Ultomiris include diarrhea, upper respiratory infections, abdominal pain, urinary tract infections, back pain, dizziness, and mild infusion reactions. Serious side effects are less common but include severe infections like COVID-19 and pneumonia, and serious infusion reactions.

Before discussing myasthenia gravis, Ultomiris was primarily used for treating paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS). Recently, there's been exploration into its potential use in treating neuromyelitis optica spectrum disorder (NMOSD), due to its impact on the complement system. However, when it comes to myasthenia gravis, Ultomiris isn't specifically approved for this use, but stay tuned to the enrichment section for more details.

60 kg to less than 100 kg (approximately 132 lb to less than 220 lb)
Myasthenia gravis is a chronic autoimmune condition where your immune system unwittingly attacks your cells. With dysfunctional muscle and nerve communication, your voluntary muscles tire quickly and weaken, causing a variety of symptoms. These typically worsen during periods of increased activity and improve with rest.

Symptoms of myasthenia gravis range from droopy eyelids and weak limbs to fatigue, blurry or double vision, trouble swallowing, and even difficulty breathing. The condition affects muscle groups throughout the body, distinguishing it from ocular myasthenia gravis, which only influences the eye muscles.
Ultomiris is prescribed for adult patients with generalized myasthenia gravis (gMG) who test positive for anti-acetylcholine receptor (AChR) antibodies. A blood test will help determine if your myasthenia gravis qualifies you for Ultomiris treatment.

By blocking the activity of the C5 protein, Ultomiris interferes with the complement system. The complement system is a group of proteins involved in the immune response, aimed at regulating immune responses and promoting inflammation. By reducing the activity of C5, Ultomiris potentially stops the activation of other complement proteins, thereby inhibiting complement-mediated tissue damage and reducing fatigue and muscle weakness.

Ultomiris's ability to treat myasthenia gravis isn't fully understood, but researchers believe its impact on the complement system contributes to its effectiveness in reducing disease symptoms.
Receiving Ultomiris for Myasthenia Gravis
Ultomiris
Ultomiris is administered in three strengths, and the dosage is based on your body weight. Your healthcare provider will recommend the ideal dosage for you. If you have questions about your Ultomiris dosage or how it will be administered, don't hesitate to ask.

Before Receiving Ultomiris
Dosage frequency
Before you receive Ultomiris, it's important to inform your healthcare provider if you have an active infection, are pregnant, are breastfeeding, drink alcohol, have had an allergic reaction to Ultomiris or its ingredients, or have any other health conditions that may affect your treatment.
once every 8 weeks
Ultomiris has a boxed warning for the risk of serious meningococcal infections. Before starting Ultomiris treatment, you'll need to be up-to-date with meningococcal vaccines. If necessary, your healthcare provider will administer any needed vaccines at least 2 weeks before you start Ultomiris treatment. If immediate treatment is needed, your healthcare provider may prescribe antibiotics to help prevent infection, which you'll take for the first 2 weeks following your first Ultomiris infusion.
once weekly for 4 weeks; your doctor may prescribe additional cycles based on how well Vyvgart works for your symptoms
The risk of serious meningococcal infections persists throughout treatment with Ultomiris and for at least 8 months after your last dose. If you experience symptoms of a meningococcal infection, contact your healthcare provider immediately. However, if your symptoms feel life-threatening, go to the closest emergency room immediately.
