VITamine D Supplementation in RenAL Transplant Recipients - VITALE
France538 participantsStarted 2012-01-06
Plain-language summary
It has been proposed that the intake of high dose of cholecalciferol may have beneficial non classical effects (beside bone health). This could include the reduction of type 2 diabetes mellitus, cardiovascular diseases, cancers, autoimmune and infectious diseases. These pleiotropic effects are mostly documented by observational and experimental studies or small intervention trials. In renal transplant recipients, vitamin D insufficiency, defined as circulating 25(OH)vitamin D (25OHD) less than 30 ng/mL, is a frequent finding and this population is at risk of the previously cited complications.The primary purpose of this study is to compare the effects of high dose vs. low dose of cholecalciferol on a composite endpoint consisting in de novo diabetes mellitus, cardiovascular diseases, de novo cancer and patient death.Renal transplant recipients between 12 and 48 months after transplantation will be randomized to blindly receive either high or low dose of cholecalciferol with a follow-up of 2 years.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
