Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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] 299170 0
To assess whether there is a relationship between serum 25(OH)D level and study endpoints
Timepoint [1] 299170 0
12 months post randomization
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] 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 [3] 299168 0
12 months post randomisation
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.
Timepoint [4] 299171 0
12 months post randomisation

Eligibility

* be able to receive first dose of study drug within 135 days of FDE symptom onset
* have an MRI brain scan that is supportive of demyelinating disease (Paty A or Paty B criteria) OR have at least one >5mm diameter T2/Flair brain lesion which must be in a periventricular, callosal, subcortical U-fibre or posterior fossa location AND must have at least one spinal cord lesion.
* an EDSS between 0 - 6.5 (inclusive)

Key exclusion criteria
Any of the following conditions will exclude a participant from the study:

* documented or likely prior neurological event consistent with a diagnosis of clinically definite MS
* treatment with beta-interferon, glatiramer acetate, natalizumab, mitoxantrone, or other chemotherapy agent specifically for demyelinating disease

Study design
Purpose of the study
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.
Masking / blinding
