About this study

This study will assess whether CA-4F can improve diagnosis of ATTR-CM in a community cardiology setting when used to screen electronic medical record data for patients suitable for follow-up investigations.

Read the detailed description

This is a prospective multicentre observational study to assess whether CA-4F can improve diagnosis of ATTR-CM in a community cardiology setting when used to screen electronic medical record data for patients suitable for follow-up investigations.

The algorithm will be used to screen electronic health records of participating cardiologists for patients suitable for PYP scans to investigate potential ATTR-CM and determine its positive predictive value.

Input parameters to the algorithm will be extracted from the pseudonymized electronic health records of patients who visited participating cardiologists in the 12 months preceding their enrolment.

The records of patients with elevated pre-test likelihood of ATTR-CM will be queried for Canadian Heart Failure Society red flag symptoms to facilitate clinical review. Participating cardiologists will review the red flag symptoms and electronic health records of patients with elevated pre-test likelihoods and document whether further investigation with PYP is clinically justified with supporting rationale.

Patients for which further investigation is clinically justified will be referred for confirmatory testing and the results of additional investigations will be documented. The positive predictive values of "moderate", "high" and "very high" CA-4F Risk Scores will be calculated by determining the percentage of those patients for which further investigations were performed and resulted in diagnosis of ATTR-CM.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CA-4FDevice

    The study intervention is the CA-4F algorithm developed by Ensho Health.

    The algorithm is a process for converting input parameters to a CA-4F Risk Score intended to facilitate clinical prioritization of patients suitable for follow-up investigation for ATTR-CM.

    The algorithm is applied using the CA-4F Likelihood Estimator which encodes it in software and records its outputs. The CA-4F Likelihood Estimator is controlled through a graphical user interface called the CA-4F Controller.

    The CA-4F Likelihood Estimator and its Controller are Class I medical devices in Canada registered under the Medical Device Establishment License of Ensho Health (license 16208).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical utility of CA-4F

    Positive predictive value of "moderate" or greater CA-4F Risk Score as confirmed by PYP scan

    Measured: Six months

Secondary outcomes (1)
  1. Optimal threshold for clinical use

    Positive predictive values of "moderate," "high," "very high," and "high" or greater CA-4F Risk Scores as confirmed by PYP scan

    Measured: Six months

Questions about this trial

What is this clinical trial studying?

A study testing CA-4F in people with Transthyretin Amyloid Cardiomyopathy ("ATTR-CM"), run by Ensho Health Intelligent Systems Inc. at 3 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 27 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical utility of CA-4F (time frame: Six months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2022.
