About this study

Official title: Impact of Vitamin A Supplementation on Disease Activity and Progression in Multiple Sclerotic (MS) Patients

The aim of this study is the comparison between the effects of supplementation with 25000 IU preformed vitamin A (retinyl palmitate) or placebo for first 6 months and 10000 IU/day for next 6 months on disease activity and progression in patients with Multiple Sclerosis.

Read the detailed description

Multiple Sclerosis (MS) is a chronic inflammatory disease where Th1 like responses from myelin-specific CD4+ T cells, as secretion of pro-inflammatory IFNγ, are believed to play a major role in the pathogenesis. The myelin-specific T cells that mediate tissue destruction in MS are believed to become activated outside the central nervous system (CNS) in lymphoid tissue and when they cross the blood brain barrier they will re-encounter their antigen. Immune deviation is the redirection of the immune response from most often Th1 like responses to Th2 like responses, even though the opposite can also occur. Vitamin A or Vitamin A-like analogs known as retinoids, are potent hormonal modifiers of type 1 or type 2 responses but a definitive description of their mechanism(s) of action is lacking. High level dietary vitamin A enhances Th2 cytokine production and IgA responses, and is likely to decrease Th1 cytokine production. Retinoic acid(RA) inhibits IL12 production in activated macrophages, and RA pretreatment of macrophages reduces IFNγ production and increases IL4 production in antigen primed CD4 T cells. Supplemental treatment with vitamin A or RA decreases IFNγ and increases IL5, IL10, and IL4 production.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing vitamin A in people with Relapsing Remitting Multiple Sclerosis, run by Tehran University of Medical Sciences at 1 site in Iran.

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 2 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 16 Aug 2011. 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 Iran. 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 phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Results are not available in the source record.

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 (EDSS) (time frame: Change from baseline at 12 months). The study lists 5 primary outcomes in all. 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 NCT01417273, which also lists 2 linked publications.

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 16 Aug 2011.
