Patient leaflet - Beyonttra 356 mg film-coated tablets

1. What BEYONTTRA is and what it is used for

BEYONTTRA contains the active substance acoramidis (as hydrochloride). It belongs to a group of medicines called transthyretin (TTR) stabilisers. A stabiliser prevents the TTR protein from breaking apart, which slows down the progression of your disease. It is used to treat adults with cardiomyopathy (a disease that affects the heart muscle) resulting from transthyretin amyloidosis (ATTR-CM).

In people with transthyretin amyloidosis, a protein called transthyretin (TTR) does not work properly, causing it to break up and form fibrous clusters called amyloids. When amyloids form in the heart, the heart muscle stiffens, and the heart can no longer work normally. BEYONTTRA stabilises TTR, which can prevent it from breaking up and forming amyloids. This helps people whose heart has been affected by transthyretin amyloidosis cardiomyopathy.
