Study summary

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.

Read the 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.

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

Groups and cohorts

  • Wear AFGen1 for at least 7 days

    Wear AFGen1 for 7 to 10 days. ECG co-measurement with 12 lead device at start and periodic measurements of ECG with AFGen1 during wear period

    Device: ECG co-measurement · Device: Periodic ECG triggered measurement

  • Misplacement Study Group

    Wear AFGen1 device in misplaced position compared to wearing device in standard position as directed by instructions for use

    Device: ECG co-measurement

Interventions

  • DeviceECG co-measurement

    Measure ECG with 12 lead device at same time that AFGen1 is monitoring ECG

  • DevicePeriodic ECG triggered measurement

    Subject triggers AFGen1 to perform an extended measurement during wear period

What researchers measure

Primary outcomes

  1. Bland-Altman Comparison

    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.

    Time frame: 1 day

  2. Qualitative Evaluation

    For the qualitative equivalence evaluation according to the two cardiologists confirmation of equivalence must be greater than 95%.

    Time frame: 1 day

  3. Adhesive performance

    The overall average wear time for the device must be greater than 7-days.

    Time frame: 7 to 10 days

Ran from Apr 2024 to primary completion in Apr 2024, 0 months.

Of 149 industry-sponsored observational studies under Atrial Fibrillation, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 44. This study's 0 months is below that.

Counting every sponsor, half of 685 studies reached it within 38 months; a quarter within 22 and three quarters within 75.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 20, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
