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   43694   clinical trials with a EudraCT protocol, of which   7248   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.

    At Day 90 an ancillary study will concern 20 patients included in Nantes and their relatives (they could be the legal representative who have signed the consent for the inclusion of their relative, or another relative ; the aim being that it should be the person closest to the patient emotionally, and that it is the same person who answers the questionnaires at M1 and M3), if they consent to.
    Semi-structured interviews will be conducted by a researcher in psychology with patients and relatives (dyads) to gain more insight into the understanding and the interpretation of quantitative data, as recommended by literature on human sciences.

    - Informed consent from a legal representative, or emergency procedure (when possible according to national regulation). If it is not possible to obtain the patient consent prior the inclusion (comatose patients), patient consent for the study continuation will be obtained as soon as deemed possible.

    • Severe hepatic insufficiency (Child Pugh score B or C)
    • Liver cytolysis with hepatic enzymes (AST and/or ALT) > 5N)
    • Severe chronic renal insufficiency (MDRD Creatinine Clearance < 10 ml/min/1.73m2)
    • Immunodepression (hematologic cancer, aplasia, chemotherapy/radiotherapy for cancer within 3 months prior to the inclusion, known infection Human immunodeficiency virus or concomitant use of any anti-graft rejection drug).
    • Coma after resuscitated cardiac arrest

    • Participation to a drug interventional study within 1 month prior to the inclusion
    • Hospital-acquired pneumonia before inclusion in the study during the current hospitalization

    E.5 End points
    E.5.1Primary end point(s)
    To demonstrate the efficiency of rHuIFN-γ for the prevention of hospital-acquired pneumonia, the primary endpoint is the composite outcome of all-cause mortality at day 28 and/or the occurrence of hospital-acquired pneumonia within 28 days after randomization.
    Hospital acquired-pneumonia is diagnosed after the 48th hour of hospitalization according to European and French guidelines (Torres et al. Eur Respir J 2017; Leone et al. ACCPM 2018) :
    - at least two of the following criteria: body temperature >38°C; leucocytosis>12000 cells per mL, leucopenia <4000 cells per mL, or purulent pulmonary secretions
    - appearance of a new infiltrate or change in an existing infiltrate on chest radiography,
    - positive culture of a respiratory tract samples from mechanically ventilated patients with quantitative culture (for patients with antibiotics < 48h) (thresholds of 104 colony-forming units (CFU) per mL for a bronchoalveolar lavage, 105 CFU/mL for a blind BAL (mini BAL) sample, and ≥105 CFU/mL for a tracheal sample). A semi-quantitative is acceptable, notably for patients with antibiotics >48h. Respiratory samples are obtained before starting any new antibiotic treatment.
    An adjudication committee, composed of 1 investigator by country who will be blinded to the trial-group assignments, will review the medical charts of patients with respiratory tract infections of the 2 other participating countries, in order to review the diagnosis.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Day 28
    E.5.2Secondary end point(s)
    The secondary outcomes to determine the efficiency of rHu-IFN-γ, on pneumonia-associated morbidity and mortality reduction are:
    -All-cause mortality at D28 and 90.
    -Hospital acquired Pneumonia at D28
    -Bacterial ecology of the 1st episode of HAP (respiratory fluids).
    -Rate of ventilator-associated tracheobronchitis at D28 defined as at least two of the following criteria : body temperature >38°C; leukocytosis>12000 cells per mL, leucopenia <4000 cells per mL, or purulent pulmonary secretions and a positive culture of a respiratory tract samples, without appearance of a new infiltrate or change in an existing infiltrate on chest radiography (Martin-Loeches et al. Lancet Respir Med 2015)
    -Acute Respiratory Distress Syndrome within 28d after randomization
    -Duration of antimicrobial therapy at D28, antibiotic free days at D28 (the number of antibiotic free days is defined as the number of days between D1 and D28 for which living patients don’t receive antibiotics. Dead patients will be ascribed 0 antibiotic free days).
    -Duration of mechanical ventilation at D90, mechanical ventilation free days at D90.
    -Duration of ICU hospitalization at D90, Duration of hospitalization at D90, hospital free days at D90.

    The secondary outcomes to determine the tolerance of rHu-IFN-γ are:
    -Rate of serious adverse effects and suspected unexpected serious adverse reaction (SUSAR) at D15.
    -Rate of leukocytosis, neutropenia, lymphopenia, thrombopenia at D15.
    -Rate of liver cytolysis (Increases in AST and/or ALT) at D15.
    -Rate of pancreatitis (Increase in Lipase) at D15.
    -Fever,headache,nausea at D15.
    -Allergic reaction at D15.
    -Injection site reaction at D15.
    -Myalgia, arthralgia, back pain at D15.

    The secondary outcomes to determine the economic efficiency of rHu-IFN-γ in the prevention of pneumonia are:
    Economic endpoints at M3:Incremental cost effectiveness ratio (ICER). We will assess the economic efficiency of the various interventions compared by performing a cost-effectiveness analysis (CEA) using QALYs (Quality-Adjusted Life-Years) as a measure of effectiveness.

    The secondary outcomes to determine the suitability and acceptability of rHu-IFN-γ from the patients’ and relatives’ perspectives are :

    Changes in health-related quality of life (HRQoL) from one (M1) to three months (M3) after randomization measured with the Short Form (SF)-36 scale validated in French, Greek, and Spanish
    Changes in anxiety and depression from M1 to M3 measured with the HADS scale validated in French, Greek, and Spanish
    Changes in subjective well-being from M1 to M3 measured with the Satisfaction With Life Scale (SWLS) validated in French, Greek, and Spanish
    At M1 and M3, these questionnaires will be filled in by the patient (patient’s perspective) and by one relative (relative’s perspective). The relatives could be the legal representative who have signed the consent for the inclusion of their relative, or another relative ; the aim being that it should be the person closest to the patient emotionally, and that it is the same person who answers the questionnaires at M1 and M3, if they consent to.

    Adaptation of the patients to their health state and its evolution from M1 to M3 using differential item functioning and response shift analyses for HRQoL, anxiety and depression.
