Other Clinical Trial - Randomized Study to Reduce Calcineurininhibitor

Status Terminated

Clinical Trial Summary

The purpose of this study is to determine if a safe reduction of cyclosporine A in pediatric and adolescent patients with stable renal graft function, reduces signs of calcineurin-inhibitor toxicity.

Clinical Trial Description

Chronic transplant nephropathy is one of the major causes of graft loss after renal transplantation. Toxicity of calcineurin-inhibitors is suspected to be one cause for loss of graft function. Therefore reduction of cyclosporine A dosing can result in longer graft survival and better graft function in patients after renal-transplantation. However, reduction of immunosuppression can result in acute rejection episodes, although it is less likely in patients with stable graft function 12 months or longer after successful renal transplantation.

Therefore the aim of this randomized, controlled study in pediatric and adolescent renal transplant recipients, is to compare the impact of reduced cyclosporine A-dosing to standard CSA-dosing on renal graft function. Therapy monitoring in both groups will be performed by obtaining CSA blood levels two hours after intake, as they provide an individual insight in pharmacokinetics in comparison to conventional trough level (C0)-measurements.

Secondary objectives to evaluate are

1. the evaluation of the health-related Quality of life and psychosocial burden in the two treatment arms.

2. measurement of the NFAT-regulated gene expression (nuclear factor of activated t-cells) of intracellular cytokines [Interleukin-2, TNF-alpha, Interferon-gamma and GMCSF) by quantitative PCR as measurement of CSA activity.

3. To obtain new insights by screening for metabolites conjunct with clinic features of nephrotoxicity or graft rejections a metabolomic screening and a targeted analysis (trimethylamine-N-oxide, neopterin and kynurenine/tryptophan ratio) will be performed. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
