ETNA-MS Device Validation Study (ETNA-MS)

March 31, 2026 updated by: Innodem Neurosciences
The overarching goal of this research protocol is to validate the effectiveness of Innodem's ETNA-MS device in informing clinicians on the disability status of Multiple Sclerosis (MS) patients. Effectiveness of the device will be assessed by the level of agreement between the EDSS estimated by the device and the actual scores measured by the neurologist in-person assessments.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

This study will use a multi-site cross-sectional design in a single cohort of Multiple Sclerosis (MS) patients. Eligible patients with MS will be selected and categorized based on their Expanded Disability Status Scale (EDSS) score. Patients eye movements will be captured using the patented eye-tracking technology at one single time point. In addition to the eye-tracking tests, patient phenotypes will be further detailed via brief functional and cognitive assessments using the EDSS, Brief International Cognitive Assessment for MS (BICAMS) and Multiple Sclerosis Functional Composite (MSFC). All patients will be required to participate in a single session.

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

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.

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.
Outcome Measure
Measure Description
Time Frame
Validate the effectiveness of the ETNA-MS device to estimate MS disease severity/status as estimated by the EDSS.
Time Frame: Day 1
Evaluate the average level of agreement (within +/- 0.5 EDSS score) between the device-estimated EDSS score and the ground truth, that is the true EDSS score as established by a certified neurologist. The Expanded Disability Status Scale (EDSS) is a method of quantifying disability in multiple sclerosis and monitoring changes in the level of disability over time. It is widely used in clinical trials and in the assessment of people with MS. The EDSS scale ranges from 0 to 10 in 0.5 unit increments that represent higher levels of disability. Scoring is based on an examination by a neurologist.
Day 1

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.
Outcome Measure
Measure Description
Time Frame
Validate that the ETNA-MS device has good test-retest reliability for estimating the EDSS.
Time Frame: Day 1
Evaluate the level of agreement between device outputs from two repeated eye-tracking tests.
Day 1
Validate the effectiveness of the ETNA-MS device to estimate the Symbol Digit Modalities Test (SDMT) as part of the Brief International Cognitive Assessment for MS (BICAMS).
Time Frame: Day 1
Evaluate the level of agreement between the device-estimated clinical scores and the ground truth scores, and between the device-estimated composite scores and the ground truth composite scores. The Brief International Cognitive Assessment for MS (BICAMS) is a battery of tests recommended by multiple sclerosis (MS) experts to monitor MS-related cognitive impairment, which includes the Symbol Digit Modalities Test (SDMT). The test presents a series of nine symbols, each paired with a single digit in a key at the top of a standard sheet of paper. Patients are asked to voice or write the digit associated with each symbol as rapidly as possible for 90 seconds. The test is scored on the number correct answers over the 90 second time span. A higher score represents lower levels of disability.
Day 1
Validate the effectiveness of the ETNA-MS device to estimate the Brief Visuospatial Memory Test-Revised (BVMT-R) as part of the Brief International Cognitive Assessment for MS (BICAMS).
Time Frame: Day 1
Evaluate the level of agreement between the device-estimated clinical scores and the ground truth scores, and between the device-estimated composite scores and the ground truth composite scores. The Brief International Cognitive Assessment for MS (BICAMS) is a battery of tests recommended by multiple sclerosis (MS) experts to monitor MS-related cognitive impairment, which includes the Brief Visuospatial Memory Test-Revised (BVMT-R). In this test, six abstract designs are presented for 10 sec. The display is removed from view and patients render the stimuli via pencil on paper manual responses. Each design receives from 0 to 2 points representing accuracy and location. Thus, scores range from 0 to 12. There are three learning trials, and the test is scored on the total number of points earned over the three learning trials. A higher score represents lower levels of disability.
Day 1
Validate the effectiveness of the ETNA-MS device to estimate the Rey Auditory Verbal Learning Test (RAVLT) as part of the Brief International Cognitive Assessment for MS (BICAMS).
Time Frame: Day 1
Evaluate the level of agreement between the device-estimated clinical scores and the ground truth scores, and between the device-estimated composite scores and the ground truth composite scores. The Brief International Cognitive Assessment for MS (BICAMS) is a battery of tests recommended by multiple sclerosis (MS) experts to monitor MS-related cognitive impairment, which includes the Rey Auditory Verbal Learning Test (RAVLT). In this test, patients listen to a 15-word list and report as many of the times as possible. There is no instruction as to the order in which items are recalled. After recall is recorded, the entire list is read again followed by a second attempt at recall. Altogether, there are five learning trials. The test is scored on the total number of recalled items over the five learning trials. The delayed recall, second list, and recognition trials are not administered in the context of this study. A higher score represents lower levels of disability.
Day 1
Validate the effectiveness of the ETNA-MS device to estimate the Timed 25-foot walk as part of the Multiple sclerosis functional composite (MSFC).
Time Frame: Day 1
Evaluate the level of agreement between the device-estimated clinical scores and the ground truth scores, and between the device-estimated composite scores and the ground truth composite scores. The Timed 25-Foot Walk is a quantitative measure of lower extremity function. The patient is directed to one end of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly as possible, but safely. The task is immediately administered again by having the patient walk back the same distance. The test is scored on the time taken to walk the two trials of the 25 feet walk. A higher score represents higher levels of disability.
Day 1
Validate the effectiveness of the ETNA-MS device to estimate the 9-Hole Peg Test (9-HPT) as part of the Multiple sclerosis functional composite (MSFC).
Time Frame: Day 1
Evaluate the level of agreement between the device-estimated clinical scores and the ground truth scores, and between the device-estimated composite scores and the ground truth composite scores. The 9-Hole Peg Test (9-HPT) is a quantitative measure of upper extremity (arm and hand) function. Both the dominant and non-dominant hands are tested twice (two consecutive trials of the dominant hand, followed immediately by two consecutive trials of the non-dominant hand). The test is scored on the time taken to complete each trial for each hand. A higher score represents higher levels of disability.
