Impact of Vitamin D Supplementation in Patients With Multiple Sclerosis

Status Completed

Clinical Trial Summary

Vitamin D is important risk factor for developing multiple sclerosis (MS) and for disease progression. Patients with MS who had lower vitamin D levels were at increased risk for more clinical attacks and faster disease progression. It was also shown that patients with MS had lower vitamin D levels in serum than healthy controls. It is not clearly defined, which are the levels of vitamin D in serum, that are high enough to trigger immunomodulatory effect and are safe for patients.

This double-blind randomized clinical trial was designed to compare impact of vitamin D supplementation in two different doses (1000 IU/day vs 4000 IU/day) in patients with relapsing remitting MS. The main goal of this trial is to compare dose response on vitamin D supplementation and to estimate more closely appropriate level of vitamin D in serum which triggers some of experimentally shown immunomodulatory actions.

Clinical Trial Description

Vitamin D is important risk factor for developing multiple sclerosis (MS) and for disease progression. Patients with MS who had lower vitamin D levels were at increased risk for more clinical attacks and faster disease progression. It was also shown that patients with MS had lower vitamin D levels in serum than healthy controls. It is not clearly defined, which are the levels of vitamin D in serum, that are high enough to trigger immunomodulatory effect and are safe for patients.

This double-blind randomized clinical trial was designed to compare impact of vitamin D supplementation during four months in winter time in two different doses (1000 IU/day vs 4000 IU/day) in patients with relapsing remitting MS. The main goal of this trial is to compare dose response on vitamin D supplementation and estimate more closely appropriate level of vitamin D in serum which triggers some of experimentally shown immunomodulatory actions. To define immunomodulatory response different laboratory, clinical and genetic tests will be performed. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
