The need for the PrevANZ trial has arisen from a now significant body of evidence for the role that vitamin D deficiency plays in MS. However, to date there has not been a clinical trial conducted to provide the necessary evidence on the benefits that can be expected from vitamin D supplementation or the correct dose.
MS Research Australia and our colleagues in the MS research community see this trial as a high priority and an area in which the expertise in Australia and New Zealand can contribute significantly to the prevention and better treatment of MS globally.
The PrevANZ Team
A steering committee of clinicians and researchers from Australia and New Zealand, with expertise in MS neurology, MS clinical trials, endocrinology and epidemiology has been assembled to oversee the trial. The trial will be coordinated and funded by MS Research Australia. This has been made possible by generous support from the state MS organisations, particularly, WA, QLD and Tasmania, as well as Foundation 5 Million+, the Trish MS Research Foundation, and the John T Reid Trust.
A collaborative team of neurologists, lead by A/Professor Helmut Butzkueven from the Department of Medicine, University of Melbourne, and Professor Bruce Taylor, Menzies Research Institute Tasmania, will undertake this study across 21 sites in Australia and New Zealand.
PrevANZ commenced recruitment in June 2013. The trial will run for four years over 2013-2016. It is expected that results will be available in 2017. PrevANZ will test 3 dosage levels of daily oral vitamin D3 supplements (1000, 5000 & 10,000 International Units) against placebo (dummy tablets) in a total of 240 people.
The role of vitamin D in MS
The evidence for the role of vitamin D deficiency in MS is now very strong and was reinforced by the internationally important Australian study (Ausimmune, 2004-2007), comparing MS patients in with CIS in Brisbane, Newcastle, Geelong and Hobart. Vitamin D deficiency is thought to play a role in MS since geographical areas of lower levels of UV radiation, and hence lower vitamin D synthesis in the skin, have higher incidences of MS. Variations in genes involved in the vitamin D metabolism pathway have been implicated in susceptibility to MS and vitamin D deficiency has also been shown to be associated with a higher rate of relapses in people with established MS.
Taking part in the PrevANZ trial
People with CIS who are interested in taking part should discuss participation with their neurologist. The sites for the trial are listed below.
Please note people who have already been diagnosed with MS are not eligible to participate in the trial. People with MS who are concerned about their vitamin D levels should seek advice from their GP or neurologist.
