About this study

Invasive intracranial pressure (ICP) monitoring is highly effective, but involves risks. HS-1000 measures ICP non-invasively by assessing the acoustic properties of the patient's head.

HS-1000 device, a proprietary non-invasive ICP monitor, is expected to safely and accurately monitor ICP with minimal discomfort to patients, and provide information about normal or elevated ICP levels to the physicians.

Read the detailed description

A prospective study will be conducted on 80 patients with an inserted invasive intraparenchymal ICP monitor. Once a patient undergoes invasive ICP monitoring, has a life expectancy of greater than 48 hours and is 14 years old and over at the screening visit, and has an intact/continuous dura layer, the patient will become a candidate for enrollment into the study. If the patient signs the informed consent or the patient's legal authorized representative signs on the patient's behalf, the patient will be enrolled into the trial. Each enrolled patient will be monitored in parallel to the invasive ICP monitor with the HeadSense's device. Once the data collection is complete, results will be analyzed by comparing ICP readings from both devices.

The primary end-point of the study is to collect 60-120 minutes of ICP monitoring data over two sessions of 30-60 minutes each for 80 neurosurgery patients of any etiology. The secondary endpoint of this study is evaluate the safety of the device as measured by incidence of adverse events and serious adverse events over each subject's 96 hours of participation.

Study groups in NCT02773888
Study groupRoleWhat they receive
HS-1000 recordingExperimentalICP readings will be recorded in parallel from both the invasive ICP monitor, and HeadSense's non-invasive ICP monitor. Each recording session will be done until an aggregate of at least 30 minutes worth of quality data is collected, depending on the patient's clinical condition. For each patient, two recording sessions will be completed for 30-60 minutes each for 120 minutes total.
Receives: Device: HS-1000

What is being measured

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

  1. Number of ICP values obtained by the HS device that correlate to ICP using current standards

    Measured: 30 minutes

Secondary outcomes (1)
  1. Incidence of adverse events during and after recording sessions

    Measured: 96 hours

Questions about this trial

What is this clinical trial studying?

A study testing HS-1000 in people with Intracranial Hypertension and Brain Injuries, run by HeadSense Medical at 5 sites in Japan.

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 5 inclusion and 6 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: paused, as of the sponsor's last update on 27 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Japan. 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?

Results are not available in the source record.

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?

Number of ICP values obtained by the HS device that correlate to ICP using current standards (time frame: 30 minutes). 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 27 Feb 2017.
