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   43846   clinical trials with a EudraCT protocol, of which   7282   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    Will GM-CSF (a drug used to stimulate white blood cells) be able to restore the ingestion of germs by neutrophils (the most important white blood cells in fighting bacterial and fungal infection) to fight off infection in critically ill patients on intensive care?
    Protection of trial subjects
    Participants were treated in routine critical care setting. All patients enrolled in the study received daily monitoring.
    Background therapy
    Patients received background care in keeping with their critical illness.
    Evidence for comparator
    In controlled trials, the incidences of renal and hepatic dysfunction were comparable between Leukine and placebo treated patients. Patients who took part in the RCT component of the received either, an injection of the drug (GM-CSF) or an injection of a solution, with no effect (placebo or dummy drug). We then compared whether those patients who received the GM-CSF injection had an improvement in the function of their neutrophils compared to those who did not.

    Recruitment
    Recruitment details
    The incapacitating nature of the condition precluded obtaining prospective informed consent from nearly all participants. Informed consent was sought from patients or a Personal or Professional Legal Representative. Due to the time dependent factors, a time limit of up to 24 hours to make a decision was given, but within 6 hrs if possible.

    Pre-assignment
    Screening details
    Daily screening of patients was performed on ICU (within 72hrs of admission). After consent, a blood sample was taken for assessment of neutrophil phagocytosis. If a patient’s phagocytosis index was >50% the patient was not recruited, ie not all patients consented were included in the dose-finding study or RCT.

    Pre-assignment subject non-completion reasons
    Reason: Number of subjects
    screen fail: 3596
    Notes
    [1] - The number of subjects reported to have started the pre-assignment period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: The total number of patients screened in ICUs was 3634. Of these only 38 were randomised into the trial and therefore 3596 patients were ineligible at various points during the screening process. Consent was obtained for 64 patients, however 26 of these were were not eligible on the basis of phagocytosis screening following consent.

    Blinding implementation details
    Randomisation was a 1:1 ratio, with stratification by site, using a web-based randomisation service in NCTU. The randomised allocation schedule was generated by a statistician with no other involvement in the study to ensure independence and concealment of allocation. Permuted blocks of variable length were used to reduce the risk of breach of concealment of allocation. A treatment number was generated for each participant that links to the corresponding allocated study drug/placebo.

    Arm description
    Each participant was randomly allocated to receive either study drug or placebo. As a placebo controlled, single-blind trial, patients, clinicians and the PIs were blinded to each patient's allocation. All trial drugs, whether GM-CSF or placebo, were packaged identically at the point of administration and identified only by a unique trial identifier.

    Dosage and administration details
    Each patient randomised to the GMCSF arm received up to 4 days of treatment with GM-CSF (sargramostim, Leukine®) as a subcutaneous injection. GM-CSF (Sargramostim, Leukine®, 250 microgram/vial) dosed on actual body weight (3mcg/kg) up to a maximum dose of 450mcg/volume 1.8ml. The dose/volume administered was prescribed according to the weight ranges given to give the dose to the nearest 5kg.

    Notes
    [2] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: milestones relate to the number randomised, and those for whom primary endpoint data was collected at Day 2, and then further data collected at Day 9 and Day 30. Some data was not collected at Days 9, however data was collected at Day 30 for all participants. Primary endpoint data would be missing if, for example, a patient died before day 2.

    Area under curve is calculated by summing the areas between each time point. This procedure is known as the linear trapezoidal rule. In cases where there is missing data with no more data either before or after that point we do not calculate the area and treat that patient’s area under curve as missing.

    Neutrophil capacity measured as ‘area under curve’ (AUC) up to day4/5
    End point description
    Area under curve is calculated by summing the areas between each time point. This procedure is known as the linear trapezoidal rule. In cases where there is missing data with no more data either before or after that point we do not calculate the area and treat that patient’s area under curve as missing. The area under the curve up to day 4/5 is calculated for each patient. The summary statistics split by arm are then calculated.
