Who this trial is looking for
This trial is looking for adults who carry a specific genetic variant that can lead to a heart condition but have not yet shown any symptoms. Participants will receive an experimental drug called acoramidis to see if it can prevent heart issues.
Are You a Good Fit for This Trial?
You may be able to join if
I am between 18 and 75 years old.
I have a genetic variant of the TTR gene that is known to cause disease.
My age is within 10 years younger or older than another participant.
You may not be able to join if
I have symptoms of heart disease or nerve problems.
I have received other treatments for TTR-related issues in the past year.
I cannot have a cardiac MRI done.
I have major organ dysfunction like kidney or liver disease.
I was diagnosed with cancer in the past 5 years.
I have untreated hyperthyroidism or hypothyroidism.
I have had major surgery in the past 3 months.
I am allergic to acoramidis.

Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque-like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid t…
Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque-like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid that may no longer be sufficiently cleared by the body. This type of ATTR is known as wild-type ATTR (ATTRwt). The other way occurs when a person inherits a defective TTR gene that causes the TTR protein to spontaneously fall apart. This form of the disease is known as variant ATTR (ATTRv) and can be detected in adults by a genetic test of their TTR gene before they age.
Amyloid build-up in the heart causes the heart wall to become thick and stiff and can result in heart failure and even death. Accumulation of TTR amyloid in the heart is known as transthyretin amyloid cardiomyopathy or ATTR-CM. Amyloid can also deposit in the nerve tissues leading to nerve problems. Accumulation of TTR in the nerves is known as transthyretin amyloid polyneuropathy or ATTR-PN.
Acoramidis is an experimental drug designed to bind tightly to TTR in the blood and stabilize its structure, so it does not form the harmful amyloid plaques that can cause damage to organs.
This study is intended to determine if treatment with acoramidis in participants with ATTRv who have not yet developed any symptoms of disease can prevent or delay the development of ATTR-CM or ATTR-PN disease. If adults with an inherited defective TTR gene are treated early before any of the symptoms of disease have developed, it may be possible to delay the onset or prevent the disease entirely.
