Clinical Trial Summary

Prospective, non-interventional, feasibility study. 8 months, from start of screening to finishing the study. Multi-center study, with a maximum of 8 centers in Europe. Health adult volunteers (21 years or older) and adult patients with a clinical indication for ambulatory outpatient cardiac monitoring.

To observe the feasibility of remotely monitoring patients with the novel µCor Heart Failure and Arrhythmia Management System (µCor system ) that non-invasively captures thoracic fluid content, electrocardiogram, heart rate, respiratory rate, activity, and body posture. tory outpatient cardiac monitoring.

Description:

The study will consist of two phases. Phase I of the study will enroll 6 healthy volunteers, who have no indication for remote cardiac monitoring. Subjects are required to participate in the study for 30 days.

Phase II of the study will enroll up to 44 patients indicated for outpatient cardiac monitoring and will participate in the study for up to 90 days.

All subjects will wear the device in two locations, one along the left midaxillary line and the other along the left midclavicular line for the first seven days.

Thereafter, for the remainder of the study, half the enrolled subjects will only wear the device in the left midclavicular position and the other half will wear the device in the left midaxillary position. Subjects will use a diary to keep a daily log their activities of daily living (phase I) or a log of any symptoms related to heart rhythm abnormalities and heart failure (phase II).

Data will be acquired with the µCor system and wirelessly transmitted daily to a remote server for processing, generating thoracic fluid content, ECG, heart rate, respiration rate, activity, and posture measurements. Investigators will have access only to ECG data.

Study staff will make weekly phone calls to subjects and record any new clinically actionable events. Patients will have monthly office visits. At the end of 30 days (phase I) or 90 days (phase II), patients will end wear and will complete the study follow-up questionnaire.

The study will enroll a maximum of 50 subjects. Six healthy volunteers will be enrolled for phase I of the study. Remaining 44 subjects will be enrolled for phase II and will have an indication of outpatient cardiac monitoring.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Logistics of Study Device Setup and Monitoring	Logistics will be assessed by the number of subjects successfully fitted with a device that was able to transmit data to the remote server. Device Setup	Period 1: Start of device wear at Day 0 to Day 7 and Period 2: Day 8 to 90
Primary	Device Wear Time and Compliance	Total number of days the device is worn at least once, in the devices indicated for long term wear in the heart arryhthmia group. These devices were worn during both Period 1 and Period 2, and the outcome measure was assessed irrespective of whether the device was being worn in Period 1 or Period 2.	Period 1: Start of device wear at Day 0 to Day 7 and Period 2: Day 8 to 90
Primary	Subject's Ability to Accurately Place Device	Subject Training will be assessed by measuring the incidence of correct device placement. Correct device placement was assessed irrespective of whether the device was being worn in Period 1 or Period 2.	Period 1: Start of device wear at Day 0 to Day 7 and Period 2: Day 8 to 90
Primary	Device Data Transmission and Device Connectivity	Count of subjects that had daily data transmission.	Period 1 and Period 2
Primary	Ability to Provide Timely Arrythmia Monitoring	Timely arrythmia monitoring will be assessed by the mean time from arrythmia event trigger to publication of arrythmia report to investigator. Timing or arrhythmia monitoring reporting was assessed irrespective of whether the device was being worn in Period 1 or Period 2.	Period 1: Start of device wear at Day 0 to Day 7 and Period 2: Day 8 to 90
Primary	Documentation of Clinically Actionable Events.	Assessed by the total number of clinical events documented including arrythmia symptoms, physician office visits, ER visits, hospitalizations, and mortality in both the healthy group and arrhythmia monitoring group. The number or clinical events documented was assessed irrespective of whether the device was being worn in Period 1 or Period 2.	Period 1: Start of device wear at Day 0 to Day 7 and Period 2: Day 8 to 90
Secondary	Thoracic Fluid Content (TFC) Front and Side Device Measurement Equivalency	The TFC measurement was compared between front and side placed devices. TFC is a unitless measurement that encompasses the degree of reflected radar waves in the lung taken by the study device. Higher TFC is indicative of increased fluid, whereas lower TFC is indicative of decreased fluid.	Period 1: Start of device wear at Day 0 to Day 7
Secondary	Association of Device Recordings to Clinical Events	Device recordings were assessed and compared to clinical events in both the healthy group and arrhythmia monitoring group. Device recording associations were assessed irrespective of whether the device was being worn in Period 1 or Period 2.	Period 1: Start of device wear at Day 0 to Day 7 and Period 2: Day 8 to 90
Secondary	Device Recording Stability	Device recording stability was assessed through the heart rate coefficient of variation in both front and side placed devices. Stability was assessed irrespective of whether the device was being worn in Period 1 or Period 2.	Period 1: Start of device wear at Day 0 to Day 7 and Period 2: Day 8 to 90
Secondary	Respiration Rate Front and Side Device Measurement Equivalency	Respiration rates were compared between front and side placed devices. The outcome was measured only during Period 1 when both front and side devices were worn simultaneously.	Period 1: Start of device wear at Day 0 to Day 7
Secondary	Activity Front and Side Device Measurement Equivalency	Activity counts were compared between front and side devices.	Period 1: Start of device wear at Day 0 to Day 7
Secondary	Sleep Angle Front and Side Device Measurement Equivalency	Sleep angle was compared between front and side devices.	Period 1: Start of device wear at Day 0 to Day 7
