About this study

Official title: Teriflunomide (Aubagio) Effects on Cognitive and Vocational Outcomes, as Related to Neurodegeneration in Multiple Sclerosis: A Prospective, Observational, Single-blinded Study.

Cognitive impairment is common in MS and has devastating impact on functional activities. There is a great demand for medications that will enhance cognitive capacity in MS patients. The effect of teriflunomide on cognition and vocational capacity is unknown. The investigators will address these questions in a sample of 30 relapsing MS patients treated with teriflunomide. Cognitive impairment will be measured by calculating an information processing speed index and a memory composite index from conventional, validated neuropsychological tests as recommended by consensus opinion publications. Vocational performance will be monitored using a newly developed online survey called the Multiple Sclerosis Vocational Monitoring Survey (MSVMS). This study will elucidate the effect of teriflunomide on these important outcomes.

Read the detailed description

Summary:

Objectives: The primary aim of this study is to define the effect of teriflunomide (Aubagio®) on cognitive abilities in patients with relapsing multiple sclerosis (MS). There are two secondary objectives, to [a] relate changes in cognition to vocational problems, and [b] determine MRI correlates of change in cognition, more specifically gray-matter (GM) volume metrics which the investigators believe reflect neurodegeneration.

Design: This is a prospective, observational, single-blinded, longitudinal study of teriflunomide effects on cognitive performance in MS patients over 24 months. Neuropsychological status and 3T (3 Tesla) MRI will be assessed at baseline, 12 months and 24 months. Vocational status will be assessed every three months via the internet. Statistical analysis will emphasize within-subjects changes in all metrics to maximize statistical power.

Study Population: Thirty (30) relapsing MS patients and 30 healthy controls (HC) will be enrolled in the study.

Outcomes: An information processing speed index and a memory composite index will be calculated from conventional, validated neuropsychological tests as recommended by consensus opinion publications. Conventional clinical metrics for overall neurological disability will also be assessed. Vocational performance will be monitored using a newly developed online survey called the Multiple Sclerosis Vocational Monitoring Survey (MSVMS). Regional GM atrophy, as defined by measurement of thalamic and cortical atrophy, will serve as neurodegeneration outcomes.

Significance of the research: The effect of teriflunomide on the development of cognitive impairment and vocational capacity is unknown. This study will elucidate the effect of teriflunomide on these important outcomes.

Relapsing MS patientsThirty (30) relapsing MS patients new to teriflunomide therapy will be enrolled.
Healthy ControlsA sample of 30 healthy control volunteers, matched on demographics with the treated group will be enrolled.

What is being measured

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

  1. Expanded Disability Status Scale Score (EDSS)

    The Expanded Disability Status Scale (EDSS). 0-10 scale with higher scores indicating more severe disability.

    Measured: 0, 12, and 24 months

  2. Timed 25-foot Walk.

    Time it takes in seconds for patient to walk 25 feet. Higher times indicate slower ambulation.

    Measured: 0, 12, and 24 months

  3. Nine-hole Peg Test

    The Nine-Hole Peg test is a measure of manual dexterity, where the time in seconds that it takes for patient to fill pegboard holes with pegs and remove them is recorded. Longer times indicate slower motor ability. The range in seconds to complete the nine-hole peg test ranges from 0-seconds to the ceiling value of 300 seconds.

    Measured: 0, 12, and 24 months

  4. California Verbal Learning Test 2nd Edition Total Learning Score

    A measure of verbal learning and memory. Patient is read a list of 16 words 5 times and asked to recall the list each time. Score 0-80 with higher scores indicating better performance.

    Measured: 0, 12, and 24 months

  5. Brief Visuospatial Memory Test Revised Total Learning Score

    A measure of visual-spatial learning and memory. Patient is shown a display 3 times and asked to recall figures from the display. Score 0-36 with higher scores indicating better performance.

    Measured: 0, 12, and 24 months

  6. Symbol Digit Modalities Test Total Correct

    A measure of cognitive processing speed. Patient is shown a key with symbol-digit pairings and several rows of symbols with empty boxes beneath them. Patient is asked to respond with the numbers that are paired with each of the symbols as quickly and accurately as they can. Score 0-120 with higher scores indicating better performance.

    Measured: 0, 12, and 24 months

Secondary outcomes (1)
  1. Change in Vocational Status

    Vocational Status assessed by the Buffalo Vocational Monitoring Survey (BVMS). BVMS includes four sections: [a] demographics and disease characteristics, [b] self-reported symptom inventories, [c] general employment information, and [d] work-related problems/accommodations. Vocational status (employed vs. unemployed) will be taken from this survey.

    Measured: 0, 12, and 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Sclerosis, run by State University of New York at Buffalo at 1 site in United States.

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 10 inclusion and 11 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: finished, as of the sponsor's last update on 24 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

Yes. Results are posted in the registry (first posted 24 Sep 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Expanded Disability Status Scale Score (EDSS) (time frame: 0, 12, and 24 months). The study lists 6 primary outcomes in all. 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 24 Sep 2021.
