Purpose

Low vitamin D levels have been shown to increase a person's risk of developing multiple sclerosis (MS), and patients with MS who have lower vitamin D levels are at increased risk of having attacks. However, it is not known if giving supplemental vitamin D to those with MS reduces the risk of attacks, and some research suggests that vitamin D could even be harmful to people with MS.

In this clinical trial, patients with relapsing-remitting MS will receive high-dose or low-dose oral vitamin D in addition to an approved therapy for MS, glatiramer acetate. Patients will be evaluated for two years, and the effect of high-dose vitamin D supplementation on the rate of MS attacks and on the number of new lesions and change in brain volume on MRI will be determined. Establishing this association will have major implications for the treatment of individuals with MS throughout the world.

Primary Outcome Measures:

Proportion of subjects that experiences a relapse [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Annualized relapse rate [ Time Frame: 2 years ] [ Designated as safety issue: No ]
Number of relapses requiring treatment [ Time Frame: 2 years ] [ Designated as safety issue: No ]
Number of new T2 lesions [ Time Frame: In the two-year study, compared to baseline ] [ Designated as safety issue: No ]
Occurrence of sustained disability progression [ Time Frame: At years 1 and 2, compared to baseline ] [ Designated as safety issue: No ]
A patient will be considered to have had sustained progression of disability if there is an increase in the Expaned Disability Status Scale score at month 12 by at least 1.0 point that is confirmed on the final examination one year later.
Change in MS Functional Composite Score [ Time Frame: Over the two-year study compared to baseline ] [ Designated as safety issue: No ]
Change in low-contrast acuity [ Time Frame: Over the two-year study compared to baseline ] [ Designated as safety issue: No ]
Change in health-related quality of life [ Time Frame: Over the two-year study compared to baseline ] [ Designated as safety issue: No ]
Change in brain parenchymal volume [ Time Frame: Over the two-year study compared to baseline ] [ Designated as safety issue: No ]
Change in normalized gray matter volume [ Time Frame: Over the two-year study compared to baseline ] [ Designated as safety issue: No ]
Change in cortical thickness [ Time Frame: Over the two year study compared to baseline ] [ Designated as safety issue: No ]
Development of hypercalcemia/related adverse effects [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
Active Comparator: Low-dose vitamin D	Drug: Vitamin D3 Patients will be assigned to low dose (600 IU/day) versus high-dose (5000 IU/day) of vitamin D3 as an add-on therapy to glatiramer acetate (Copaxone).
Active Comparator: High-dose vitamin D	Drug: Vitamin D3 Patients will be assigned to low dose (600 IU/day) versus high-dose (5000 IU/day) of vitamin D3 as an add-on therapy to glatiramer acetate (Copaxone).

Detailed Description:

Vitamin D insufficiency has recently emerged as a risk factor for susceptibility to multiple sclerosis (MS). Our observational data suggest that lower vitamin D levels in patients with relapsing-remitting MS are associated with a higher subsequent relapse rate. However, it is unknown if providing vitamin D supplementation to such patients leads to a reduction in the risk of an exacerbation. Historically, several nutritional supplements that appeared to be helpful in observational studies of various diseases did not demonstrate a benefit or were harmful in randomized trials. Further, a vitamin D response element was recently identified in the promoter region of HLA-DRB1*15, the gene believed to be critical to initiating the autoimmune response in MS, and 1, 25-dihydroxyvitamin D3 increases the expression of the gene in vitro, suggesting that vitamin D supplementation could even be harmful in established MS.

This is a randomized, double-blind trial of high- versus low-dose vitamin D3 supplementation as an add-on to glatiramer acetate in 172 patients with relapsing-remitting MS. Subjects will be randomized to 600 IU or 5000 IU of oral vitamin D3 daily for two years. A standardized brain MRI scan will be performed at baseline and at the end of the first and second years. The impact of high-dose vitamin D supplementation on the number of relapses, the number of new lesions on brain MRI, and the change in brain volume will be assessed. Establishing these associations will have major implications for the treatment of patients with MS throughout the world and will provide rationale for further investigations of the role of vitamin D in the immunopathogenesis of MS, possibly leading to the identification of new therapeutic targets.
