Outcomes
Primary outcome [1] 287975 0
To determine the relative efficacy of oral, daily, Vitamin D3 (1,000IU or 5000IU or 10,000IU) compared with placebo, in reducing the risk of recurrent disease activity (clinical demyelinating event or MRI activity) in the 12 months following onset of a first demyelinating event.
Timepoint [1] 287975 0
12 months following onset of a first demyelinating event.
Secondary outcome [1] 299168 0
To assess whether a beneficial clinical and/or radiological response exists for oral Vitamin D supplementation in preventing MS in high-risk FDE participants
Timepoint [1] 299168 0
12 months post randomisation
Secondary outcome [2] 299169 0
To assess whether there is a dose response relationship between study medication and the study endpoints
Timepoint [2] 299169 0
12 months post registration
Secondary outcome [3] 299170 0
To assess whether there is a relationship between serum 25(OH)D level and study endpoints
Timepoint [3] 299170 0
12 months post randomization
Secondary outcome [4] 299171 0
To determine if oral Vitamin D3 therapy has an acceptable side effect and safety profile by monitoring the adverse events over the 12 months. Blood calcium will be monitored at each timepoint because there is the unlikely possibility that it may increase.

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants presenting to the Neurology Department will be assessed to determine their eligibility.

If the participant gives informed consent, they will be randomized to either placebo or 3 arms of active drug.

Allocation to treatment will be concealed by numbered bottles allocated to sites using central computerised allocation system.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be based on simple randomization created by computer software to promote balanced randomization with equal numbers in each arm, stratified by site/centre.

Summary
Brief summary
There is a great deal of lay information to suggest that people with MS or at risk of MS should take oral Vitamin D supplementation. However, no adequately powered scientific study has examined the role of Vitamin D3 supplementation as prevention or treatment for MS. There is insufficient commercial interest in conducting such a study, but the need for evidence is great. If effective, oral Vitamin D supplementation could provide a low cost MS therapy with virtually no side effects.

Sponsored by Multiple Sclerosis Research Australia, we therefore plan to conduct a randomised, placebo controlled, double-blind clinical trial to assess the efficacy of oral Vitamin D3 in preventing the development of Multiple Sclerosis in participants at high risk of MS (participants with a first demyelinating event, FDE).

We will compare three doses of oral daily vitamin D3 (1,000IU 5,000IU or 10,000IU/day) to placebo. After agreeing to participate, participants will be randomly and blindly assigned to one of these four study arms and will continue to take study medication for 48 weeks.

Scope: We plan to enrol 240 participants with FDE from 21 Australian and New Zealand MS trial centres over the course of three years. We may invite additional centres depending on recruitment and trial progress.
