Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Healthy Cohort The target population for this cohort is healthy adult volunteers who do not have preexisting heart or lung conditions or illness. The goal is to recruit a participant population with a range of body types and BMIs and an approximately even split of genders. Pathologic Cohort The target population for this cohort is adult patients who have been diagnosed with cardiopulmonary conditions. These can include chronic pulmonary conditions, chronic cardiac conditions, and those who are taking diuretic medications, living with heart failure, Chronic Obstructive Pulmonary Disorder (COPD), or recovering from coronary-artery disease related events. The goal is to recruit a participant population with a range of body types and BMIs and an approximately even split of genders as well as conditions outlined above (e.g. at least 5 each of COPD, HF, recovering from a coronary artery disease related event, and taking diuretic medication).

About this study

Official title: Clinical Validation Study for Noninvasive Cardiopulmonary Management Device.

The ADI At-Home CPM (Cardiopulmonary Management) System is a non-invasive device that measures and trends a variety of biological parameters.

This study will be conducted as a prospective non-randomized study with two study arms/cohorts - one of healthy adult patients, one of pathologic patients who fit into the intended use population of the CPM System.

Being tested
Noninterventional and noninvasive
Medical subject headings
Pulmonary Heart Disease

What participants receive

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

  • Noninterventional and noninvasiveDiagnostic test

    The ADI At-Home CPM (Cardiopulmonary Management) System is intended for adults undergoing monitoring for cardiopulmonary conditions under the direction of a licensed medical professional to measure, record, and periodically transmit physiological data.

What is being measured

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

  1. Correlation Coefficient for Accuracy of Test Device vs Reference Device

    Correlation Coefficient for Respiration Rate accuracy (test device vs reference device).

    Measured: Device reading (3 minutes)

  2. Root Mean Square Error Accuracy Between CPM and Reference Device for Respiration Rate

    Measured: Device reading (3 minutes)

  3. Correlation Coefficient Between Reference Tidal Volume (TV) and Test Device Relative Tidal Volume (rTV)

    Accuracy of CPM System calculated rTV (relative Tidal Volume) as compared to reference device calculated TV (Tidal Volume)

    Measured: Device reading (3 minutes)

  4. Standard Deviation of Thoracic Impedance

    Analyses were performed to quantify replication variability. The analysis used Mixed models for repeated measures (MMRM) to obtain the variance component estimates controlling for changes in true status as measured by the bioimpedance reference. The variance components include replication variance within application with three measurements per application (i.e., short-term variance) and application variance with three applications, including an application one hour later (longer-term variance). The model also includes subject to subject variance (adjusted for changes in the bioimpedance reference). Variability among applications is partially explained by changes in bioimpedance reference. Total variance is partitioned into measurement variance, application variance, and subject variance.

    Measured: device reading (3 minutes)

  5. Magnitude of Drift for Thoracic Impedance

    The magnitude of drift was evaluated by comparing the magnitude of this longer-term variance to the short term (replication) variance in relative term and comparing the absolute incremental contribution of the longer-term standard deviation to 6 ohms. If adding application variance (controlling for change in bioimpedance reference) does not appreciably increase the total nonsubject variance, no appreciable drift across will have been demonstrated.

    Measured: Device reading (3 minutes)

Secondary outcomes (4)
  1. ECG Heart Rate Confirmation

    Confirm that ECG characteristics align with those from bench results using a simulator

    Measured: Device measurement (3 minutes)

  2. Skin Temperature Confirmation.

    Confirm that ECG characteristics align with those from bench results using a simulator

    Measured: Baseline

  3. ECG Confirmation for Abnormal Rhythms

    Comparing device ECG Abnormal Rhythm Flags raised by CPM system to cardiologist atrial fibrillation annotation of device ECG strips (3 strips per participant). Counts determine total number of ECG strips flagged with abnormalities if the CPM device or cardiologist annotated atrial fibrillation.

    Measured: Device measurement (3 minutes)

  4. ECG QRS, QT and QTc Confirmation

    Confirm that ECG characteristics align with those from bench results using a simulator

    Measured: device reading (3 minutes)

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiopulmonary Disease, run by Analog Device, Inc. at 1 site in United States.

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 15 inclusion and 19 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: finished, as of the sponsor's last update on 6 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

Yes. Results are posted in the registry (first posted 6 Aug 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Correlation Coefficient for Accuracy of Test Device vs Reference Device (time frame: Device reading (3 minutes)). The study lists 5 primary outcomes in all. 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 6 Aug 2024.
