Summary
Brief summary
The VITATOPS study is a multi-center, randomized, double blind, placebo-controlled secondary
stroke prevention trial to determine whether the addition of vitamin supplements (B12 500 ug,
B6 25 mg, Folate 2 mg) to best medical/surgical management (including modification of risk
factors) will reduce the combined incidence of recurrent vascular events (stroke, myocardial
infarction) and vascular death in patients with recent stroke or transient ischemic attack
(TIA). All patients presenting to one of the participating neurologists or general physicians
within seven months of stroke (ischemic or hemorrhagic) or TIA (eye or brain) are eligible
for this trial. Eligible patients will be randomized in a double-blind fashion to receive
multi-vitamins or placebo, 1 tablet daily. The primary outcome event is the composite event
"stroke, myocardial infarction, or death from any vascular cause", whichever occurs first.
Our target is to recruit a total of 8,000 patients over the next two years with a median
follow-up of 2.5 years. Recruitment to the trial began in November 1998 and is planned to
continue until December 2005. We aim to complete final follow-up by the end of 2006. However,
the Steering Committee will be flexible in dictating the need for ongoing recruitment and
continuing follow-up, depending on the overall rate of the primary outcome event in the
entire cohort at each interim analysis.
