About this study

Official title: Pharmacodynamic and Immunologic Effects of Vitamin D Supplementation in Patients With Multiple Sclerosis and Healthy Controls

This is a pilot study of oral vitamin D supplementation to determine if patients with Multiple Sclerosis (MS) and healthy individuals attain a similar increase in serum 25-hydroxyvitamin D levels. The investigators will also assess whether the immunologic or relevant gene expression response to oral vitamin D supplementation differs in patients with MS and healthy controls.

Being tested

What participants receive

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

Vitamin D3ExperimentalBoth those with MS and healthy controls will be given vitamin D3 5000 IU/day by mouth for 90 days.
Receives: Dietary Supplement: Vitamin D3

What is being measured

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

  1. Change in Mean Serum Level of 25-hydroxyvitamin D

    Generalized estimating equations (GEE) with an autoregressive with lag one correlation matrix were used to compare the serially-measured serum 25(OH)D levels between MS patients and Healthy Controls (HCs) to take into account repeated measures and within-subject correlations.

    Measured: Baseline to 90 days

Secondary outcomes (4)
  1. Change in Percentages of T Cell Subsets (IFNγ+ and IL-17+)

    Analyzed the mean percentage change in IFNγ+ and IL-17+ cluster of differentiation 4 (CD4) + cells (post- versus pre- supplementation). This represents a change between two time points (90 days versus baseline).

    Measured: Baseline, 90 days

  2. Gene Expression Microarray

    We had initially planned to do whole blood gene expression. The experience gained by the laboratory that was to perform this since the original trial was planned was that this measure is too noisy and would not yield meaningful results. Thus, this analysis will no longer be conducted.

    Measured: 90 days

  3. Change in Cytokine Levels

    The original plan had been to measure the change in basic serum cytokine levels (e.g. IL-17, interferon gamma; IL-10; pg/microliter). However, due to emerging data suggesting low utility of these measures, this plan was abandoned.

    Measured: 90 days

  4. Change in Percentage of B Cells

    The change in percentage (day 90-baseline) was originally planned for study. Due to the limited number of patients with samples this plan was abandoned.

    Measured: 90 days

Questions about this trial

What is this clinical trial studying?

A study testing Vitamin D3 in people with Multiple Sclerosis, Relapsing-remitting, run by Johns Hopkins University at 2 sites 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 13 inclusion and 26 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 5 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 1 Feb 2016). 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?

Change in Mean Serum Level of 25-hydroxyvitamin D (time frame: Baseline to 90 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01667796, which also lists 1 linked publication.

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 5 Mar 2019.
