Watch how VYVGART works

Learn how VYVGART, a first-of-its-kind treatment, works in the body of adults with anti-AChR antibody positive generalized myasthenia gravis (gMG‍).

The body has many “characters” that influence how your muscles and brain work together to help you move. Expand below to learn more about some of the characters that play a role in the VYVGART treatment journey.

ACh

Acetylcholine (ACh) help carry messages from the brain to different parts of the body, including muscles.

AChR

Acetylcholine receptor (AChR) is a type of receptor (message receiver) found in muscles. These receptors receive messages from nerves that tell muscles what to do. 

IgG

Immunoglobulin G (IgG) antibody is a Y-shaped protein made by the immune system. Antibodies—like IgG—play a vital role in helping protect your body from infection and disease.  

Harmful AChR Antibody

Harmful acetylcholine receptor (AChR) antibodies disrupt communication between muscles and nerves.

FcRN

Neonatal Fc receptor (FcRn) is a receptor that attaches to IgG antibodies and helps IgG antibodies stay in the body longer.

VYVGART is the first FDA-approved treatment that uses a fragment of an IgG antibody to treat adults with anti-AChR antibody positive gMG

What is the most important information I should know about VYVGART® (efgartigimod alfa-fcab)?

VYVGART may cause serious side effects, including:

  • Infection. VYVGART may increase the risk of infection. In a clinical study, the most common infections were urinary tract and respiratory tract infections. More patients on VYVGART vs placebo had below normal levels for white blood cell counts, lymphocyte counts, and neutrophil counts. The majority of infections and blood side effects were mild to moderate in severity. Your health care provider should check you for infections before starting treatment, during treatment, and after treatment with VYVGART. Tell your health care provider if you have any history of infections. Tell your health care provider right away if you have signs or symptoms of an infection during treatment with VYVGART such as fever, chills, frequent and/or painful urination, cough, pain and blockage of nasal passages/sinus, wheezing, shortness of breath, fatigue, sore throat, excess phlegm, nasal discharge, back pain, and/or chest pain.
  • Undesirable immune reactions (hypersensitivity reactions). VYVGART can cause the immune system to have undesirable reactions such as rashes, swelling under the skin, and shortness of breath. In clinical studies, the reactions were mild or moderate and occurred within 1 hour to 3 weeks of administration, and the reactions did not lead to VYVGART discontinuation. Your health care provider should monitor you during and after treatment and discontinue VYVGART if needed. Tell your health care provider immediately about any undesirable reactions.

Before taking VYVGART, tell your health care provider about all of your medical conditions, including if you:

  • Have a history of infection or you think you have an infection
  • Have received or are scheduled to receive a vaccine (immunization). Discuss with your health care provider whether you need to receive age-appropriate immunizations before initiation of a new treatment cycle with VYVGART. The use of vaccines during VYVGART treatment has not been studied, and the safety with live or live-attenuated vaccines is unknown. Administration of live or live-attenuated vaccines is not recommended during treatment with VYVGART.
  • Are pregnant or plan to become pregnant and are breastfeeding or plan to breastfeed.

Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

What are the common side effects of VYVGART?

The most common side effects of VYVGART are respiratory tract infection, headache, and urinary tract infection.

These are not all the possible side effects of VYVGART. Call your doctor for medical advice about side effects. You may report side effects to the US Food and Drug Administration at 1-800-FDA-1088.

What is VYVGART?

VYVGART is a prescription medicine used to treat a condition called generalized myasthenia gravis, which causes muscles to tire and weaken easily throughout the body, in adults who are positive for antibodies directed toward a protein called acetylcholine receptor (anti-AChR antibody positive).
