Trial summary

The purpose of this research study is to investigate the effectiveness of MS Disease modifying medications on cognitive fatigue in persons with relapsing remitting multiple sclerosis (RRMS). Cognitive fatigue is the kind of fatigue that occurs after intense mental concentration as after a session of problem solving. Read more about this study

About this study

Official title: A Biomarker for Cognitive Fatigue Using Functional Imaging in MS

The purpose of this research study is to investigate the effectiveness of MS Disease modifying medications on cognitive fatigue in persons with relapsing remitting multiple sclerosis (RRMS). Cognitive fatigue is the kind of fatigue that occurs after intense mental concentration as after a session of problem solving.

Read the detailed description

The researchers aim is to investigate the effects of disease modifying treatments on cognitive fatigue and on specific brain areas that have been shown to underlie cognitive fatigue in individuals with Multiple Sclerosis (MS). The researchers will investigate the effects on the cognitive fatigue that develops during the performance of a demanding task, and also on how cognitive fatigue changes as a function of duration of treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • OcrevusDrug

    Participants with MS will be divided into two treatment groups: those who will begin to take Ocrevus (the "early Ocrevus" group (EO), and those who plan to be begin treatment with Glatimer acetate SC (Copaxone) (EC). Both groups will be matched to the EO group for age, gender and education. The HC group will be free of neurological disease or injury and will be matched to the EO group for age, gender, and education.

What is being measured

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

  1. Brain activation (BOLD signal)

    A change in brain activation as measured with functional magnetic resonance imaging through blood oxygen level dependent signal will be measured in association with cognitive fatigue (as measured by the Visual Analogue scale during performance of the modified Symbol Digit Modality and Modified Fatigue Impact Scale).

    Measured: Measured for change at 3 time points (before, six months and 12 months after intervention)

Secondary outcomes (1)
  1. Fatigue onset

    A change in the speed with which modified Symbol Digit Modality task (a cognitively demanding task) induces fatigue in MS (as measured by the Visual Analogue scale and Modified Fatigue Impact Scale).

    Measured: Measured for change at 3 time points for change (before, six months and 12 months after intervention)

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Sclerosis, Relapsing-Remitting, run by Kessler Foundation 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 4 inclusion and 6 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 11 Aug 2026. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Brain activation (BOLD signal) (time frame: Measured for change at 3 time points (before, six months and 12 months after intervention)). 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 11 Aug 2026.
