The effect of vitamin supplementation, genotype and homocysteine on
migraine frequency and severity in females diagnosed with migraine with aura.
Scientific title
A Phase II randomised double-blind placebo-controlled clinical trial of vitamin supplementation in females diagnosed with migraine with aura, incorporating methylene tetrahydrofolate reductase (MTHFR) genotype analysis, to determine whether vitamin therapy is an effective complementary or alternative therapy for reducing migraine disability.

Outcomes
Primary outcome [1] 5571 0
To assess the effect of vitamin supplementation in migraine patients we will measure the 12-month retrospective migraine disability using the Migraine Disability Assessment Score (MIDAS) - a measure of migraine impact on quality of life. This post-treatment score will be compared to the baseline MIDAS score to establish the primary outcome variable (i.e. change in MIDAS score).
Timepoint [1] 5571 0
At zero year and at one year after randomisation.
Secondary outcome [1] 9382 0
Change in plasma homocysteine and vitamin levels will be assessed through a National Association of Testing Authorities (NATA) accredited laboratory using B6 plasma assay and homocysteine, folic acid and B12 serum assays.
Timepoint [1] 9382 0
At zero year and at one year after randomisation.

Eligibility
Key inclusion criteria
Female aged 18 to 65 years of age.
Have a diagnosis of migraine with aura (MA) according to International Headache Society Criteria.
Unrelated by first degree - we hypothesise that our outcome variable, response to vitamin therapy, is influenced by inherited factors, so genetic independence of participants is important.
Suffer at least 4 migraine episodes per year.
Of Caucasian ancestral background.
Participants with adequate venous access in their left and right arms to allow collection of a number of blood samples via venepuncture.
Fluent in the English language.
Have voluntarily given written informed consent to participate in this study.
Be able to attend the Genomics Research Centre (GRC) clinical trials facility on the Gold Coast.
Minimum age
18 Years
Maximum age
65 Years

Can healthy volunteers participate?
No
Key exclusion criteria

History of any psychiatric illness.
Inability to comply with treatment regime or attend clinic assessments.
Participation in another clinical trial or received experimental therapy within last 30 days.
Donated or lost a significant amount of blood (e.g. 550 mL) within the past 12 weeks.
