VYVGART Hytrulo for subcutaneous injection and VYVGART for intravenous (IV) infusion have not been proven to treat a specific symptom or group of symptoms.
The most common antibody subtype of gMG. About 85% of people living with gMG have anti-AChR antibody positive gMG.
People living with this type of gMG may experience face, mouth, and throat symptoms more severely than other subtypes.
The rarest antibody subtype of gMG. People living with anti-LRP4 antibody positive gMG may start out with milder symptoms compared to anti-AChR antibody positive and anti-MuSK antibody positive gMG.
People living with triple seronegative gMG have gMG symptoms, but harmful antibodies are not found in blood tests.
It’s thought that harmful antibodies may still be present, but at levels too low to detect. Or, there may be a different harmful antibody that hasn’t been discovered yet.
The immune system helps keep us healthy. IgG antibodies play a vital role in providing that protection. But with gMG, some IgG antibodies can be harmful. These harmful IgG antibodies disrupt messages between nerves and muscles.
