About this trial

The overall aim of this observational study is to generate real-world evidence on the pre- and post-diagnosis disease journeys, including baseline characteristics, treatment patterns and selected clinical, economic, and humanistic outcomes (for example Health Related Quality of Life (HRQoL), Neuropathy impairment score, activities of daily living (ADL) assessments) in patients with ATTR amyloidosis, and to better understand how the disease is presented.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients aged >18 years at study index date AND

A reported diagnosis code for amyloidosis OR

A claim for ATTR-specific treatment OR

A positive biopsy for amyloidosis and positive immunostaining result of biopsy for ATTR

Disqualifiers

Evidence of primary (AL) and secondary (AA) amyloidosis AND/OR

At least one claim/procedure code for stem cell transplant or at least two claims/procedure codes for chemotherapy and autoimmune disease drugs which may represent AL (primary) or AA (secondary) amyloidosis treatments

Trial population

This study will include data from patients aged \> 18 years with a diagnosis of ATTR amyloidosis or other evidence confirming ATTR amyloidosis. Patients will be followed until exit from the database (loss to follow-up), death, or end of database period (data collection). Baseline data will apply a lookback period of 12 months. Patient identification will be from 2014-01-01 onwards
