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   43889   clinical trials with a EudraCT protocol, of which   7298   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
    1. To assess the efficacy of Aerucin®, administered as a single dose in addition to standard antibiotic regimen, in terms of clinical cure at day 14, i.e., resolution of the P. aeruginosa pneumonia event diagnosed at enrollment, as compared to standard antibiotic therapy alone. 2. To assess the clinical safety and tolerability of Aerucin® in the study population.
    Protection of trial subjects
    All subjects are hospitalized and monitored for vital function and safety.

    Recruitment
    Recruitment details
    		 Patients with a documented diagnosis of pneumonia, who are requiring ICU care and who are intubated are eligible for screening. Assuming all other eligibility criteria are met, randomization and treatment will be based on identifying P. Aeruginosa as pathogen causing pneumonia.

    Pre-assignment
    Screening details
    		 Screening is divided in two parts. The first part is the pre-screening phase, all subjects with a pneumonia, who are intubated, treated on the ICU and who have a signed Informed consent can move to the second part of screening. In this phase an airway sample (BAL, mini-BAL or ETA) is obtained and sent to the Microbiology Lab or a rapid test is bein

    		 Post-hoc Analysis of Clinical Cure Rates Day 14 and 21 Study1
    End point description
    Using the appropriate clinical severity, level of CRP and adequate antibiotic criteria, patients were subdivided into subgroups to identify a pattern in the clinical cure rates in both treatment groups. The results suggest the presence of heterogeneity of factors influencing the clinical cure rates, where only a quite small sample is evaluable. A subset of patients had the following characteristics and were found to belong to 1. appropriate clinical Severity 2. inadequate antibiotic regimen and 3. lower 3rd quartile of level of CRP

    		 Post-hoc Analysis of Clinical Cure Rates Day 14 and 21 Study2
    End point description
    Using the appropriate clinical severity, level of CRP and adequate antibiotic criteria, patients were subdivided into subgroups to identify a pattern in the clinical cure rates in both treatment groups. The results suggest the presence of heterogeneity of factors influencing the clinical cure rates, where only a quite small sample is evaluable. A subset of patients had the following characteristics and were found to belong to 1. appropriate clinical Severity 2. inadequate antibiotic regimen and 3. lower 3rd quartile of level of CRP

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    04 May 2018
    This amendment was made in response to further considerations and clarifications of the study design, data integrity, and patient safety. Major updates included, but not limited to: Clarification of clinical cure rates with standard of cure antibiotic regimen Update of rapid diagnostic testing device GeneXpert® PA Cartridge, with addition of CE mark and IUO/RUO Addition of 19 years minimum age for South Korea Addition of third stratification (Country of Origin) Addition of no impact on treatment disclaimer Addition of severity status and biomarker sample tests Removal of time 0 for vital signs control Minor editorial changes, change of relapse to re-infection/new infection, and of VABP with VAP; addition of the terminology ‘quantitative/semi quantitative’ for culture tests and change of the IMP name to AR-105
    09 Nov 2018
    The changes to the protocol were made as a result of the approval of the revised Clinical Cure criteria to be used in a post hoc efficacy assessment by an adjudication committee. The changes included: Section 2: Clarification of Clinical Cure (CC) rates with standard of cure antibiotic regimen in the primary clinical efficacy objective. Removal of Day 4 and reordering of CC rates and removal of adjudication by independent committee in the secondary clinical efficacy objective Section 3.1: Specification of patients with VAP caused by P. aeruginosa; addition of clarification for ETA sample collection, randomization process (including subpopulations with different baseline oxygen status), procedures (CC criteria) used by an adjudication committee (AC), pneumonia causing pathogen and antibiotic treatment limit of 14 days, addition of reference to best practices for the choice of SOC antibiotics. Removal of comparison of culture results between laboratories and assessment of therapy by AC Section 4.3: Removal of withdrawal criteria: occurrence of any medical condition, SAEs, pregnancy, prohibited medication, protocol compliance; addition of loss to follow-up and clarification of study continuation through Day 28 Section 6.5: Removal of reference to AC, additional confirmation of randomization at earliest possible time and nearest specimen collection for microbiological outcome assessment, correction of computation of SOFA scores at set dates Section 7.3: Addition of central laboratory and clarification of ‘eradicated’ criteria All sections (where applicable): Change of ‘relapse’ to ‘re-infection/new infection’, and of VABP with VAP; addition of the terminology ‘quantitative/semi quantitative’ for culture tests and standardization of the font formatting of the ® trademark on the IMP name AR-105

    Interruptions (globally)
    Were there any global interruptions to the trial? No

    Limitations and caveats
    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Although the efficacy of AR-105 was not superior to placebo in 159 patients, a post-hoc analysis revealed a numeric difference of over 20% (absolute value) in clinical cure rate in favor of AR-105 in a subgroup of patients.
