Comparison of the Non-invasive ICP HeadSense Monitor vs Lumbar CSF Pressure Measurement

October 29, 2019 updated by: HeadSense Medical
In current practice patients with a suspected increase of intracranial pressure (ICP) will undergo a lumbar puncture with measurement of cerebral spinal fluid (CSF) pressure (as a marker for ICP). A lumbar puncture is an invasive and sometimes painful procedure. Using a new type of ICP monitor (HeadSense) it is possible to measure ICP non-invasively through an acoustic signal

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this study we will prospectively collect relevant clinical data on 60 neurological patients, who are being referred for an elective lumbar puncture (eg. suspected multiple sclerosis, raised intracranial hypertension, etc). Each enrolled patient will be monitored in parallel to the lumbar puncture with the HeadSense ICP monitor. Subjects who meet the study inclusion and exclusion criteria will be enrolled in the study.

Step 1: 10 minute measurement of HeadSense monitor. Once the patient is inclined with his upper body 30 degrees to the bed the pressure values, the clinical procedure can begin. The device must be preset in a continuous monitoring mode. The continuous monitoring allows a loop of measurements for an unlimited time in a rate of four measurements per minute.

Step 2: 10 minute measurement of HeadSense monitor in supine position.

Step 3: Patient will be placed in a left lateral position. The lumbar puncture will be done and CSF pressure will be measured following standard procedures.

Step 4: 10 minute measurement of HeadSense monitor in supine position.

Lumbar puncture and HeadSense measurement will be done by two different doctors and they will not share measurement values during the procedure.

After the study the patient's ears will be examined for internal ear infection or irritation that might be caused by the ear buds. Patient adverse events will be documented on the case report forms in case they occurred and the family or advocate of the patient will be informed. In case of clinical relevant adverse events appropriate clinical action will be taken.

As the procedure does not affect the patient management, there is no need to provide any specific medical care related to the trial. Patients will receive the relevant clinical care related to their clinical management, without any consideration to their participation in the trial.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

EXPERIMENTAL: HS-1000 recording

Device: HS-1000

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: 10 minutes
10 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
