About this study

The COOL-BP study is part of the Remote Hypertension Program and will investigate the data provided by Aktiia Bracelet (a cuffless Blood Pressure monitor at the wrist) when integrated into the Remote Hypertension Program.

The COOL BP study aims to compare weekly and monthly Blood Pressure averages measured manually by traditional Home Blood Pressure Monitoring to those measured automatically by the Aktiia bracelet.

Read the detailed description

This is a prospective open-label single arm study. The investigational device of this study is the Aktiia Bracelet device. Aktiia Bracelet is a non-invasive blood pressure (BP) monitor intended to track systolic and diastolic Blood Pressure trends. The Aktiia Bracelet can also measure heart rate.

Participants who consent to participate in COOL-BP will be shipped an Aktiia device to participants' residence.

For 6 months, patient will continue the procedures of the Remote Hypertension Program in parallel to wearing the Aktiia Bracelet. The Remote Hypertension Program is run remotely according to a clinical algorithm, where study navigators contact patients at regular intervals and monitor symptoms by regular phone calls; laboratory tests are obtained to ensure safety of the protocol's prescribed medications. Any symptoms will be evaluated by the program nurse practitioner or physician and managed per standard of care. During the study, the patient completes several surveys to give opinion on Aktiia product versus Home Blood Pressure Monitoring.

Following six months of using the Aktiia.product, the participant's participation in this study will end. Participants continued participation in the Remote Hypertension Program will depend on whether participants have met the blood pressure goals outlined in that program.

What participants receive

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

  • Aktiia BraceletDevice

    Aktiia Bracelet is a CE-marked medical device that will be used in accordance with its instructions for use. The optical signals at the wrist are recorded non-invasively by means by the Aktiia bracelet. The Blood Pressure measurements are further determined from these optical signals and are compared to weekly and monthly Blood Pressure averages measured manually by traditional Home Blood Pressure Monitoring.

What is being measured

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

  1. Diastolic and Systolic Pressures differences between weekly Diastolic and Systolic pressures averages provided by Home Blood Pressure Monitoring and by Aktiia 24h data.

    Diastolic and Systolic Pressures are measured weekly manually by traditional Home Blood Pressure Monitoring and continuously with the Aktiia bracelet.

    Measured: 6 months

  2. Diastolic and Systolic Pressures differences between monthly Diastolic and Systolic pressures averages provided by Home Blood Pressure Monitoring and by Aktiia 24h data.

    Diastolic and Systolic Pressures are measured monthly manually by traditional Home Blood Pressure Monitoring and continuously with the Aktiia bracelet.

    Measured: 6 months

Secondary outcomes (2)
  1. Diastolic and Systolic Pressures Circadian profiles

    Analysis of the evolution of Diastolic and Systolic Pressures circadian profiles of each patient during the study.

    Measured: 6 months

  2. Quality of life surveys

    Participants complete the same survey at Day 30, Day 60 and Day 180 to give a feedback on participants' satisfaction and comfort regarding Aktiia product compared to Home Blood Pressure monitoring. Part of answers to surveys are based on satisfaction scales from 0 to 10 where 0 = "bad" and 10 = "good".

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Aktiia Bracelet in people with Hypertension, run by Aktiia SA 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 4 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 24 May 2023. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Diastolic and Systolic Pressures differences between weekly Diastolic and Systolic pressures averages provided by Home Blood Pressure Monitoring and by Aktiia 24h data. (time frame: 6 months). The study lists 2 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?
