About this study

Official title: Prospective Double Blind Multicentre Randomized Trial of Vitamine D Estimating the Profit of a Treatment by Vitamin D3 at the Dose of 100000 UI by Comparison With a Treatment in the Dose of 12 000 UI at Renal Transplanted Patients

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.

Read the detailed description

Rationale :

Vitamin D cannot be considered any more as only necessary to prevent rickets or osteomalacia. Calcitriol produced in the kidney is known to have classical endocrine PHOSPHOCALCIC properties. More recently, vitamin D has been shown to play an important role in reducing the risk of many chronic diseases including type 2 diabetes mellitus, cardiovascular diseases, cancers, autoimmune and infectious diseases. These effects may be secondary to local production of calcitriol and to its autocrine and paracrine actions on cellular proliferation and differentiation, apoptosis, insulin and renin secretion, interleukin and bactericidal proteins production. These pleiotropic effects are mostly documented by observational and experimental studies or small intervention trials that most often evaluated intermediate parameters. In renal transplant recipients, vitamin D insufficiency (circulating 25OHD<30 ng/mL or 75 nmol/L) , is a frequent finding with more than 80% of patients displaying this profile.

Objective:

Primary objective: compare the effects of high dose vs. low dose of cholecalciferol on a composite endpoint including

  • De novo diabetes mellitus (fasting glycemia > 7 MMOLES/l or glycemia > 11 MMOLES/l)
  • Cardiovascular complications (acute coronary heart disease, acute heart failure, lower-extremity arterial disease, cerebrovascular disease).
  • De novo cancer,
  • Patient death.

Secondary objectives : compare the effects of high dose vs. low dose of cholecalciferol on

  • The occurrence of each event constituting the primary endpoint
  • Blood pressure and blood pressure control (number and dosage of antihypertensive drugs)
  • Echocardiography findings
  • Infection including opportunistic (CMV, pneumocystis, nocardial infection, cryptococcal infection, aspergillosis)
  • Acute rejection episode
  • Renal allograft function including estimated glomerular filtration rate and proteinuria - Graft survival
  • PHOSPHOCALCIC biological and clinical relevant parameters : Evolution of serum 25OHD, calcaemia, phosphataemia, serum PTH, bone mineral density and incidence of fractures
  • Renal lithiasis

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. 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 8 Sep 2025. 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 France. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

De novo diabetes mellitus (time frame: 2 years). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01431430, which also lists 2 linked publications.

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 8 Sep 2025.
