Trial summary

Experimental studies of the experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis, indicate that the number of calories fed to mice prevent EAE and are also associated with less severe disease in mice who do develop the disease. Read more about this study

About this study

Experimental studies of the experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis, indicate that the number of calories fed to mice prevent EAE and are also associated with less severe disease in mice who do develop the disease. Currently, whether these results translate favorably in humans is unknown. This is a pilot trial of testing two caloric restriction (CR) diets versus a control diet in multiple sclerosis (MS) patients: one continuous caloric restriction (CR) diet where a small number of calories will be restricted every day or another intermittent CR diet where a caloric intake will be restricted more severely 2 days per week. Participants are randomized to one of the diets, and for the first 8 weeks, will receive standardized, prepared meals tailored to the specific diet. At the conclusion of the controlled feeding study, all participants will transition to an unblinded phase for an additional 40 weeks where they are provided with instructions to follow an intermittent CR diet.

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

  • DietOther

    Diet, standardized to the 50th percentile for macronutrients, will be provided at varied calorie levels as described.

What is being measured

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

  1. Adverse events

    Adverse events will be categorized by organ system and by the blinded neurologist's assessment of the relation to the diet.

    Measured: 8 weeks

Secondary outcomes (11)
  1. Adherence to Calories Assigned

    Adherence will be assessed by comparing the total caloric intake provided to the patients through the assigned diet to the total energy intake determined by the research dieticians.

    Measured: 8 weeks

  2. Adherence to Calories Assigned

    Adherence during the "advice-only" phase will be compared to adherence in each diet group during the first 8 weeks using paired t-tests, where the grouping is done naturally by subject.

    Measured: 48 weeks

  3. Adverse Events

    Adverse events will be categorized by organ system and by the blinded neurologist's assessment of the relation to the diet.

    Measured: 48 weeks

  4. Quality of Life Questionnaire

    "Functional Assessment in MS" results will be assessed during the study

    Measured: 48 weeks

  5. NIH Patient-Reported-Outcomes Measurement Information System (PROMIS )Fatigue Questionnaire

    PROMIS Fatigue results will be assessed during the study

    Measured: 48 weeks

  6. Change in metabolite ratios

    The impact of each calorie restriction diet versus control diet on the metabolomics profile will be assessed.

    Measured: 8 weeks

  7. Immune cell subsets/cytokines

    The impact of each calorie restriction diet versus control diet on ratios of immune cell subsets (e.g. T-helper (TH)17, TH1, TH2, T regulatory) and related cytokines will be assessed.

    Measured: 8 weeks

  8. Change in concentration of measures of metabolism

    The impact of each calorie restriction diet versus control diet on fasting glucose, insulin, leptin, ghrelin, C-reactive protein, lipids, and long-chain ceramides will be assessed.

    Measured: 8 weeks

  9. Change in serum lipid concentration

    The impact of each calorie restriction diet versus control diet on fasting lipids and long-chain ceramides will be assessed.

    Measured: 8 weeks

  10. Change in serum brain-derived neurotrophic factor concentration (BDNF)

    The impact of each calorie restriction diet versus control diet on fasting BDNF will be assessed.

    Measured: 8 weeks

  11. Change in levels of oxidative stress biomarkers

    The impact of each calorie restriction diet versus control diet on protein carbonyls, 8-isoprostane, nitrotyrosine, and 4-hydroxynonenal adducts will be assessed.

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Diet in people with Relapsing Remitting Multiple Sclerosis, run by Johns Hopkins University 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 11 inclusion and 9 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 17 Nov 2017. 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. Some participants in this study may receive a placebo. 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?

Adverse events (time frame: 8 weeks). 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 17 Nov 2017.
