About this study

A prospective, open, randomized trial, in which the investigators aim to achieve optimal immunosuppression after renal renal transplantation with maximal reduction of side effects, especially of vascular injury, chronic allograft nephropathy, osteoporosis and malignancies. Immunosuppression without steroids and CNI minimization is compared to standard immunosuppression, consisting of tacrolimus OD, mycophenolic acid and corticosteroids.

Read the detailed description

Before transplantation 300 patients will be randomized 1:1:1 in three groups. Group 1 will be treated with basiliximab induction and a three day course of steroids followed by a steroid free maintenance regimen consisting of standard-dose tacrolimus OD and mycophenolic acid. Group 2 will be treated with Basiliximab induction followed by standard-dose tacrolimus OD, mycophenolic acid and steroids. Group 3 will be treated with basiliximab induction followed by standard-dose tacrolimus OD for six months, whereafter the dose will be reduced plus mycophenolic acid and steroids. The total study period will be 2 years. Primary endpoint will be renal function, proteinuria and microalbuminuria measured 24 months after transplantation. Renal function will be measured by serum Creatinine, Creatinine clearances and CKD-EPI. Secondary endpoints will be the degree of tubular atrophy and interstitial fibrosis and the degree of arteriolar hyalinosis in renal biopsies taken at 12 and 24 months after transplantation. Biopsies will be evaluated according to the Banff Criteria for Renal Allograft Biopsy Interpretation. Quantitative morphometric analysis of interstitial fibrous tissue will be performed using the digital image analysis technique. Other secondary endpoints are patient and graft survival, the incidence of allograft rejection, cardiovascular accidents, pulse wave velocity, blood pressure, the number of antihypertensives, lipid profile, the incidence of malignancies, the incidence of infectious complications, the incidence of post transplant diabetes mellitus and the development of osteoporosis.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing tacrolimus OD, mycophenolic acid, prednisolone in people with Renal Insufficiency and Kidney Transplantation, run by University Medical Center Groningen at 3 sites in Netherlands.

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 1 inclusion and 5 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 11 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Netherlands. 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?

renal function parameters (time frame: 24 months). 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 NCT01560572, 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 11 Jan 2022.
