A Multicenter Pilot Study to Investigate Ocular Involvement and the Potential of Ocular Imaging for Non-invasive Screening for Transthyretin Amyloid Cardiomyopathy (ATTR-CM)
AstraZeneca
Summary
This multicenter pilot study will enroll adult participants with a confirmed clinical diagnosis of transthyretin amyloid cardiomyopathy (ATTR-CM) and heart failure (HF) controls with documentation within the past 2 years that either excludes ATTR-CM or indicates a low probability of ATTR-CM. Ocular imaging and other study data will be collected to assess the feasibility of developing and preliminarily evaluating a machine learning model to discriminate ATTR-CM cases from HF controls without ATTR-CM.
Description
A participant who does not complete the study within 90 days from enrollment will be discontinued from the study. A participant may be discontinued from the study at any time at the discretion of the investigator for behavioral or compliance reasons. A participant may withdraw from the study at any time at the participant's own request for any reason (or without providing any reason) without any implication on participant's rights.
