Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   44313   clinical trials with a EudraCT protocol, of which   7357   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    General information about the trial
    Main objective of the trial
    To assess the frequency of delayed graft function (DGF) in donation after circulatory death (DCD) renal transplant recipients treated with GSK1070806
    Protection of trial subjects
    This study uses standard of care (SoC) aligning study tasks with SoC tasks and visit schedule to mitigate participant study-burden. Additionally, participants are required to use additional anti-infective protocols due to the potential of GSK1070806 to increase immunosuppression.

    Primary: Number of participants requiring dialysis during the first 7 days post transplant

    		 Number of participants requiring dialysis during the first 7 days post transplant [1]
    End point description
    The requirement of dialysis (except as needed for hyperkalemia during the first 24 hours [hrs]) were used to assess the frequency of delayed graft function (DGF) in donation after circulatory death (DCD) renal transplant recipients treated with GSK1070806. The ‘Analysis Population’ (AP) is defined as participants in the ‘All Subjects’ Population who have been declared to have DGF or have reached 7 days. Statistical analysis was carried out using Bayesian methodology. The proportion of participants with DGF was 0.57, highest Posterior Density (HPD) 95% Credible interval (CI) (0.25,0.90). The posterior probability for the proportion of participants with DGF <30% was 0.07 (HPD 95% CI [0.00,1.00]). The posterior probability for the proportion of participants with DGF <50% was 0.34 (HPD 95% CI [0.00,1.00]).

    End point description
    Blood samples were collected to measure serum creatinine at the indicated timepoints to assess graft function in DCD renal transplant recipients treated with GSK1070806. Baseline value was the latest pre-dose assessment value. Change from Baseline was post Baseline value minus Baseline value. Only those participants with data available at the specified time points were analyzed (represented by n=X in the category titles). 99999 indicates data is not available as standard deviation could not be calculated due to n=1.

The appearance of IL-18 marks the initiation of the inflammatory response leading to further injury. Blood samples were collected at indicated time points to assess serum levels of free, total, and GSK1070806 bound IL-18. Baseline value was the latest pre-dose assessment value.
