How does AMVUTTRA® work?

AMVUTTRA works with your body's natural system to slow the production of abnormal TTR protein, which leads to fewer harmful amyloid deposits being formed.

AMVUTTRA starts reducing TTR protein after the first dose, which lasts with continued treatment. TTR protein was reduced by an average of 88% over 18 months in a clinical study of adults treated with AMVUTTRA.
