About this study
Official title: Folic Acid for Vascular Outcome Reduction in Transplantation.
This study is being done to compare arteriosclerotic cardiovascular disease in kidney transplant recipient taking a standard multivitamin versus those taking a multivitamin augmented by a high dose combination of folic acid, vitamin B12, and vitamin B6.
Read the detailed description
This is a multicenter, randomized, double-blind controlled clinical trial. The trial has been designed to determine whether total homocysteine lowering treatment with a standard multivitamin augmented by a multivitamin containing no folic acid B12, and vitamin B6, versus treatment with an identical multivitamin containing no folic acid, will reduce the pooled rate of recurrent or new cardiovascular disease outcomes or events. Participants will have a brief visit, at which the participant will have physical measurements, blood pressure and history taken. Urine and blood tests will be performed to determine the levels of homocysteine, vitamins and creatinine. Qualifying participants will be randomly assigned to receive multivitamins containing a high dose of folic acid, vitamin B6, and vitamin B12, or an identical multivitamin containing no folic acid, and estimated average requirement amounts of vitamin B6 and vitamin B12. The participant will be required to return annually throughout the next five years for physical exams, blood and urine tests.

What is being measured
The primary outcome is the main question the study is designed to answer.
Estimated Average Requirement (EAR) amounts
to determine whether total homocysteine (tHcy)-lowering treatment with a standard multivitamin augmented by a high dose combination of folic acid, vitamin B12, and vitamin B6, versus treatment with an identical multivitamin containing no folic acid, and Estimated Average Requirement (EAR) amounts of vitamin B6 and vitamin B12., reduces the pooled rate of recurrent and de novo cardiovascular disease [CVD]outcomes
Measured: basline to death or common end date 4.5 years

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Multivitamin in people with Kidney Transplant Recipients, run by Mayo Clinic at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Estimated Average Requirement (EAR) amounts (time frame: basline to death or common end date 4.5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Apr 2012.
