About this study

Official title: Dose-related Effects of Vitamin D3 on Immune Responses in Patients With Clinically Isolated Syndrome and Healthy Control Participants. An Exploratory Double Blind Placebo Randomised Controlled Study.

The primary purpose of this study is to assess the immune response to vitamin D supplementation at two doses (5,000 IU and 10,000 IU daily) in both healthy controls and patients with clinically isolated syndrome compared to placebo. Secondary endpoints include (1) disease outcome in the clinically isolated syndrome in terms of clinical relapses and evidence of new lesions on MRI (McDonald's MS), 2) Safety of doses used

Read the detailed description

Primary endpoint: To determine the effects of vitamin D supplementation at two doses a) 5,000 IU daily b) 10,000 IU daily compared to c) placebo a 24 weeks period on the change from baseline in frequency of CD4 T cell subsets and cytokine responses by peripheral blood mononuclear cells in 1) patients with the clinically isolated syndrome. 2) healthy control participants.

Secondary endpoints:

  1. To determine whether there is a dose response effect of supplementation using 5,000 IU and 10,000 IU of vitamin D versus placebo over 24 weeks on the change from baseline in the frequency of CD4 T cell subsets and cytokine responses by PBMC in 1) patients with the clinically isolated syndrome (CIS) 2) healthy control participants
  2. To establish whether there is a clinical response to vitamin D measured by a) change in the number of T2 lesions and Gadolinium enhancing lesions on MRI scanning at 24 weeks compared to baseline b) reduction in relapses over 24 weeks in treated (both 5,000 IU and 10,000 IU) CIS patients versus CIS patients receiving placebo.

What is being measured

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

  1. The effects of two doses of vitamin D and placebo therapy on the change in the frequency of CD4 T cell subsets and cytokine responses of PBMC over 24 weeks of therapy from baseline.

    A number of measures will be examined in particular IL-10 production and the frequency of Th17 cells.

    Measured: This outcome measure will be assessed at baseline and at 24 weeks.

Secondary outcomes (3)
  1. The number of new T2 and gadolinium enhancing lesions compared to baseline amongst the study group.

    The MRI out-come measure will assess the a) number of Gadolinium enhancing lesions b) the number of new and enlarging T2 lesions c) the combined unique lesion count (new and enlarging T2 lesions plus Gadolinium enhancing lesions) after 24 weeks of therapy in the three arms, 5000IU, 10,000IU vitamin D and placebo . Mean and median new T2 and gadolinium-enhancing lesions at 24 weeks (end of the trial) will be compared for each treatment allocation group. In addition the mean and median number of new T2 lesions plus gadolinium enhancing lesions in all the CIS patients on vitamin D will be compared to the mean and median in the placebo group.

    Measured: Baseline and 24 weeks

  2. Relapse occurrence in the CIS patients during 24 weeks of the trial

    Relapse occurrence in the CIS patients during 24 weeks of the trial;(i) annualised relapse rates (ARR), (ii) percentage of patients free from relapses and (iii) time to first relapse will be compared for each treatment allocation group. In addition the same relapse measures will be applied to both vitamin D treated groups combined and compared to those in the placebo group.

    Measured: At each clinic visit or as the need arises.

  3. The percentage of CIS patients in each treatment arm free from any evidence of disease activity (No relapses, no new T2 lesions, no gadolinium enhancing lesions).

    Measured: At 24 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing 5000IU vitamin D and 10000IU vitamin D in people with Clinically Isolated Syndrome and Multiple Sclerosis, run by University College Dublin at 1 site in Ireland.

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 0 inclusion and 8 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 3 May 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 Ireland. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

The effects of two doses of vitamin D and placebo therapy on the change in the frequency of CD4 T cell subsets and cytokine responses of PBMC over 24 weeks of therapy from baseline. (time frame: This outcome measure will be assessed at baseline and at 24 weeks.). 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 NCT01728922, 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 3 May 2017.
