About this study

The purpose of this study is to demonstrate the use of a digital health offering in the management of persistent hypertension during chronic anti-hypertensive treatment.

Read the detailed description

In patients with persistent essential systolic hypertension,who are undergoing assessment of their current pharmaceutical burden for blood pressure control, a digital health offering is used (1) to provide automatic and passive electronic documentation of medication adherence and patterns of medication taking, (2) to assist providers in distinguishing inadequate medication adherence or pharmacologic unresponsiveness as the root cause for persistent hypertension, and (3) to inform management decisions (dose adjustment, medication addition or substitution, adherence counseling, referral to a hypertension specialist).

Participating patients wear an adhesive Wearable Sensor ("Patch") continuously with replacement after one week, and ingest an inert tablet ("Pill") containing an Ingestible Sensor daily whenever they take their prescribed anti-hypertensive drugs.

The Patch automatically detects and records the dates and times of each "Pill" ingestion, daily step count, sleep duration and sleep interruptions, and the circadian pattern of rest and activity. After completion of each Patch's use, the recorded data are downloaded and incorporated into a report that includes blood pressures that are obtained at the time of clinic visits at the beginning and after 2 weeks of service use.

The final report is generated automatically and provided electronically to practitioners for review with their patient. The information that is obtained is incorporated by practitioners in advising next steps for blood pressure management.

What participants receive

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

  • Ingestible Sensor and Wearable SensorOther

    This digital health offering passively acquires and records medication-taking and habits of daily living.

What is being measured

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

  1. Frequency of Medication-taking (% Taking Adherence)

    Percent timing adherence is determined by the number of ingestion sensors detected by the wearable monitor, divided by the total number of ingestion sensors prescribed, for the 2 week-time frame.

    Measured: 2 weeks

  2. Pattern of Medication-taking (% Scheduling Adherence)

    Percent scheduling adherence is determined by the number of ingestion sensors detected within a ± 2-hour time window around the prescribed dosing period, divided by the number of ingestion sensors detected by the wearable sensor during that dosing period, over the 2-week time frame.

    Measured: 2 weeks

Secondary outcomes (3)
  1. Proportion of Patients Capable of Achieving Blood Pressure Control on Existing Treatment

    Percentage of participants

    Measured: 2 weeks

  2. Change in Systolic and Diastolic Blood Pressure After Use of Digital Health Offering

    Decrease in systolic and diastolic blood pressure (measured in mm Hg) after 2 weeks when compared to baseline

    Measured: 2 weeks

  3. Blood Pressure Management After Use of Digital Health Offering

    Summary of provider actions following review of final report with patient (dose or medication change, adherence counseling, referral to a hypertension specialist)

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Essential Hypertension, run by Proteus Digital Health, Inc..

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 7 inclusion and 5 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 16 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

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 16 Jun 2017). 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?

Frequency of Medication-taking (% Taking Adherence) (time frame: 2 weeks). 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?

On the ClinicalTrials.gov record for NCT02553512, which also lists 1 linked publication.

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 16 Jun 2017.
