The exploratory ELIOS study aims to assess the value of novel investigational Eye Movement Biomarkers (EMBs) in tracking disease-related changes among a real-world cohort of Canadian patients with active RRMS, within the context of disease-modifying treatment (i.e., ofatumumab). To that end, the study will use the patented investigational, Eye Tracking Neurological Assessment (ETNA-ProgMS) SaMD (v1.0.11 or later), which has not yet received Health Canada approval, to reliably and accurately track eye movements with precision.

Time frame: 3-, 6-, 12-, and 24-months
2a. Change in Annual Relapse Rate (ARR)
MS relapse is defined as the appearance of a new neurological abnormality or worsening of a previously stable or improving pre-existing neurological abnormality, separated by at least 30 days from onset of a preceding clinical demyelinating event. The abnormality must have been present for at least 24 hours and must have occurred in the absence of fever (\< 37.5°C) or of a known infection.
Time frame: 12 and 24 months from baseline
2b. Change in patient disability measured by Expanded Disability Status Scale EDSS
The EDSS is an ordinal scale used for assessing neurologic impairment in MS based on a neurological examination. It consists of scores in each of seven functional systems (FSs) and an ambulation score that are then combined to determine the EDSS steps (ranging from 0 \[normal\] to 10 (death due to MS). The FSs are Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel \& Bladder, and Cerebral functions
Time frame: 3,6,12,24 months from baseline
2b. Change in patient disability measured by Timed 25-foot walk test (T25-FW)
The T25- is an objective quantitative test of neurological function. It is an ambulation measurement assessing speed of walking: a timed (in seconds) walk of 25 feet (7.62 meters)
Time frame: 3,6,12,24 months from baseline
2b. Change in patient disability measured by the 9-hole peg test (9-HPT)
The 9- is an objective quantitative test of neurological function. It is measured to assess both right and left arm scores, the metric is the time, in seconds, required to insert and remove nine pegs. The 9-HPT will be administered 4 2 trials per hand, the time for each trial will be averaged with lower times indicating better performance
Time frame: 3,6,12,24 months from baseline
2c. Change in objective measures of cognitive impairment as measured by the Symbol Digit Modalities Test (SDMT)
The SDMT is an objective measure of information processing speed and associated cognitive dysfunction in patients with MS. Using a reference key, the patient has 90 seconds to pair specific numbers with given geometric figures in writing. The raw score corresponds to the total number of correct substitutions, ranging between 0 and 110 with higher scores indicative of better performance.
Time frame: 3,6,12,24 months from baseline
2c. Change in objective measures of cognitive impairment as measured by the Brief Visuospatial Memory Test (BVMT-R)
The BVMT-R is a measure of visuospatial learning, the test consists of six abstract symbols on a sheet of paper. Participants are given ten seconds to study the figures and then try to draw them in the same order on a blank page. Performance is scored on accuracy and location with 0-2 points per symbol for a maximum of 12 points per trial. Patients are asked to repeat the task three times with higher scores indicative of better performance
Time frame: 3,6,12,24 months from baseline
2c. Change in objective measures of cognitive impairment as measured by the Rey Auditory Verbal Learning Test (RAVLT)
The RAVLT is a test of verbal memory that requires the participant to learn and recall a list of 15 words that are orally presented. This test measures learning across five trials, retrieval of the target list after presenting a distracter list and a 30-minute delay, followed by recognition of the target words from among distracter words such as semantic and phonemic foils. The total learning score is the sum of correct answers across the five trials, with higher scores indicative of better performance.
Time frame: 3,6,12,24 months from baseline
3a. Association between EMB and annual relapse rate (AAR)
Association of change in each investigational EMB and ARR established at 12 and 24. To estimate the association of change between each investigational EMB and ARR a Poisson or Negative Binomial Generalized Linear Mixed Model (GLMM) will be used. The metric to assess the association of change over time between each investigational EMB and the outcome variable will be the fixed effect of investigational EMB on ARR, as estimated by the GLMM
Time frame: 12 and 24 months
3b. Association of EMBs and objective measures of disability - EDSS, T25-FW, and 9-HPT
