About this study

Transthyretin (TTR) is a protein made by the liver that helps transport thyroid hormone and vitamin A in the blood. In some people, this protein breaks down and forms harmful clumps called amyloid. TTR amyloid gets deposited in the heart wall and stops it from pumping blood properly, which may lead to heart failure. The breakage in TTR protein can be age-related (wild-type ATTR-CM), or genetic (variant ATTR-CM). The study drug, acoramidis, works by attaching itself to the TTR protein, making TTR more stable and less likely to break down and form amyloid (clumps). This helps to slow down the progression of the disease, improve heart function, and increase the TTR levels in the blood. Acoramidis is an approved treatment for wild-type or variant ATTR-CM in Europe and the United States. Tafamidis is another drug that stabilizes TTR and prevents it from breaking down. In this study, acoramidis will be studied in participants with ATTR--CM who were previously treated with tafamidis. The main purpose of this study is to assess the change in blood TTR levels after participants are switched from tafamidis to acoramidis. This will be studied to understand if acoramidis causes an increase in blood TTR levels beyond the levels achieved with tafamidis. For this, the researchers will measure the change in the levels of TTR protein in participants' blood after 6 months of the treatment with acoramidis, or earlier if a participant stops the treatment before reaching that six-month mark. …
