About this study

Official title: Multicenter, Open-Label, Randomized Study on Steroid-Free Immunosuppression, in Comparison With Daily Steroid Therapy, in Pediatric Renal Transplant : Impact on Growth, Bone Metabolism and Acute Rejection

The present study investigates the safety and efficacy of steroid withdrawal at six days post-transplant in pediatric renal recipients under concomitant immunosuppression based on antibodies anti IL2 (interleukin 2), Tacrolimus (TAC) and Mycophenolate Mofetil (MMF). To investigate the impact of this protocol in growth, bone metabolism, insulin- sensitivity and evaluate the expression of IL17 (interleukin 17) and mRNA FOXP3 (messenger ribonucleic acid forkhead box protein 3) as early markers of acute rejection (blood, urine and renal biopsy).

Hypothesis:Steroid withdrawal in renal pediatric transplant patients improves growth and bone metabolism without increasing the risk of acute rejection. The expression of FoxP3/IL17 in urine cells could be an early molecular markers of acute rejection.

Read the detailed description

The intention of this investigation is to evaluate a prospective immunosuppressive protocol based on antibodies anti IL-2 (Ac-IL-2), Tacrolimus (TAC) and Mycophenolate Mofetil (MMF)and withdrawal steroids in renal transplant and to compare with a steroid-based protocol.

Objectives:

  1. To evaluate growth and the impairment in the GH/IGF (growth hormone/insulin like growth factor) axis
  2. To determine the impact of steroids on bone metabolism (biochemical parameters, DXA and pQCT)
  3. To determine the steroid effect on metabolic factors (dyslipidemia, insulin- sensitivity and arterial hypertension)
  4. To determine acute rejection incidence (protocol renal biopsy)
  5. To evaluate the expression of IL-17 and mRNA FoxP3 as early markers of acute rejection (blood, urine and renal biopsy).

Two treatment regimes (Arms)will be compared in randomized form in the course of 12 months after transplantation.

Arm A: TAC + MMF + withdrawal of steroids over a six-days following randomization.

Arm B: TAC + MMF + prednisolone (see schedule)/day

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tacrolimus (TAC)+ Mycophenolate Mofetil (MMF) + Withdrawal Prednisone and Tacrolimus (TAC)+ Mycophenolate Mofetil (MMF) + prednisolone in people with Kidney Diseases, run by Fondo Nacional de Desarrollo Científico y Tecnológico, Chile at 1 site in Chile.

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 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 10 Nov 2015. 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 Chile. 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 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?

Yes. Results are posted in the registry (first posted 10 Nov 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Stimulation of Growth After 12 Months (Delta Z-score) (time frame: 12 months). 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 10 Nov 2015.
