Clinical Trial Summary

The overarching goal of this research protocol is to acquire eye-tracking, cognitive, and disease-severity metrics in MS patients to train machine learning algorithms that will support the development and performance assessment of a sensitive and non-invasive eye-tracking software application. The training of our machine learning classifying algorithms to identify which eye-tracking metrics-or combination thereof-can serve as reliable markers of MS disease severity and cognitive status.

Description:

This study will use a single group design in a cohort of 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.

Eligibility

Inclusion Criteria:

• Able to provide informed consent

• Aged 18 years or older at the time of enrollment

• Able to read in either French or English

• Able to read the oculomotor task on-screen instructions at the testing distance (45cm) with or without corrective lenses

• Confirmed diagnosis of MS as per the Macdonald criteria, irrespective of MS subtype (relapsing-remitting (RRMS), secondary-progressive (SPMS), primary-progressive (PPMS), and progressive-relapsing (PRMS))

• Neurologist-determined EDSS score between 1.0-8.0

Exclusion Criteria:

• Presence of comorbid neurological conditions to avoid eye movement anomaly confounds (Strabismus, cranial nerve palsy, stroke-causing hemianopsia)

• Diagnosis of macular edema or other pre-existing ocular conditions that would prevent a participant from performing the eye movement assessments

• Having started a new prescription medication or having changed the dose of a medication known to influence ocular motor visual function (e.g. benzodiazepines, antipsychotics and anticonvulsants) within the past three months

• Participants with non-disease related physical impairments to a leg, hand, or arm (e.g., broken bone or severe sprain) that would not allow completion of the assessments

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Predictive power of eye-movement biomarkers (EMBs) for MS severity in relationship to Expanded Disability Status Scale (EDSS)	Estimate the extent to which EMBs can accurately predict MS severity (as assessed with the EDSS tool). 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	Predictive power of eye-movement biomarkers (EMBs) for cognitive status in relationship to the Symbol Digit Modalities Test (SDMT) as part of the Brief International Cognitive Assessment for MS (BICAMS).	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
Secondary	Predictive power of eye-movement biomarkers (EMBs) for cognitive status in relationship to the Rey Auditory Verbal Learning Test (RAVLT) as part of the Brief International Cognitive Assessment for MS (BICAMS).	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
Secondary	Predictive power of eye-movement biomarkers (EMBs) for cognitive status in relationship to the Brief Visuospatial Memory Test-Revised (BVMT-R) as part of the Brief International Cognitive Assessment for MS (BICAMS).	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
Secondary	Predictive power of eye-movement biomarkers (EMBs) for physical disability in relationship to the Timed 25-foot walk as part of the Multiple sclerosis functional composite (MSFC).	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
Secondary	Predictive power of eye-movement biomarkers (EMBs) for physical disability in relationship to the 9-Hole Peg Test (9-HPT) as part of the Multiple sclerosis functional composite (MSFC).	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.	Day 1
