Further Study of AFGen1 Clinical Performance (CS3)

June 18, 2024 updated by: TriVirum, Inc.

A Further Study of the Clinical Performance of AFGen1

AFGen1 is indicated for use on symptomatic or asymptomatic adults who are at risk of developing or who have atrial fibrillation, where a software assisted analysis of ambulatory ECG is needed to identify episodes of Afib. The purpose of this study is to establish further evidence for the clinical performance of AFGen1 on human participants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The primary purpose of this study is to demonstrate the ECG signal acquired by the AFGen1 device is of adequate quality and is suitable to support its intended use for the detection of Afib. This will be evaluated by comparing the ECG data acquired by AFGen1 to that acquired by an FDA cleared 12-lead ECG device using a Bland-Altman analysis of the R-R intervals and R amplitude measurements and Eigenvector magnitudes derived from principal component analyses of simultaneously captured waveforms measured by both devices by both devices. The ECG waveforms from both devices will also be adjudicated by 2 independent cardiologists. The study will also seek to demonstrate that there is no degradation in the quality of the ECG signal it acquires when the device is placed in an anticipated misplacement position to that directed by the instructions for use of the device. Finally the study will seek to confirm the adhesive performance of the device is appropriate to support its intended use per the requirements of sections 4.4 and 5.4 of ANSI AAMI EC12-1 . Another purpose of the study is to collect extended 5 minute ECG recordings by the subject periodically triggering the device while wearing the device for 7 (+3) days. This data will be used for product development purposes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

The study shall involve up to twenty (20) participants divided into 2 cohorts. The first study cohort will comprise up to fifteen (15) participants (at least 5 male and 5 female) who will wear the device for 7 days. The second cohort of five (5) participants will participate in the misplacement part of the study

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Bland-Altman Comparison
Time Frame: 1 day
The waveform characteristics for both the 7- day wear and misplacement elements of this study, the limits of agreement (LoA) from the Bland-Altman analyses shall not exceed the the maximum allowed clinically significant difference between methods i.e. 80ms for R-R. 0.2 mV for R-peak amplitude) for 95% of the subjects on a per-subject basis.
1 day
Qualitative Evaluation
Time Frame: 1 day
For the qualitative equivalence evaluation according to the two cardiologists confirmation of equivalence must be greater than 95%.
