Transthyretin-Associated Amyloidoses Outcome Survey (THAOS)
Transthyretin-associated Amyloidosis Outcomes Survey (Thaos): A Global, Multi-center, Longitudinal, Observational Survey Of Patients With Documented Transthyretin (Ttr) Mutations Or Wild-type Ttr Amyloidosis

THAOS is a global, multi-center, longitudinal observational survey open to all patients with transthyretin-associated amyloidoses (ATTR), including ATTR-PN (polyneuropathy), ATTR-CM (cardiomyopathy) and wild-type ATTR-CM. It is open-ended with a minimum duration of 10 years. Patients will be followed as long as they are able to participate.

The principal aims of this outcome survey are to better understand and characterize the natural history of the disease by studying a large and heterogenous patient population. Survey data may be used to develop new treatment guidelines and recommendations, and to inform and educate clinicians about the management of this disease.

Inclusion Criteria:

  • Written informed consent.
  • Patient has confirmed: genotyped TTR mutation with or without a diagnosis of TTR-associated amyloidosis (e.g., ATTR-PN, ATTR-CM), or Wild-type TTR-associated amyloidosis with cardiomyopathy (wild-type ATTR-CM).
  • Confirmation of wild-type ATTR-CM will be determined by one of the following set of criteria (A or B):

A. Presence of amyloid in cardiac biopsy tissue confirmed as TTR amyloid by immunohistochemistry and genotyped confirmation that patient does not possess a known mutation in TTR gene (i.e., is a carrier of wild-type allele only) via genetic testing; or B. Evidence of cardiac involvement by echocardiogram as defined by mean left ventricle wall thickness of > 12 mm, and presence of amyloid in non-cardiac tissue confirmed as TTR amyloid by immunohistochemistry, and genotyped confirmation that patient does not possess a known mutation in TTR gene (i.e., is a carrier of wild-type allele only) via genetic testing.

Exclusion Criteria:

  • Patient has primary or secondary amyloidosis.
