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   43874   clinical trials with a EudraCT protocol, of which   7294   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.

    • Fever (as defined by the investigator)
    • Dysuria
    • Urinary urgency
    • Urinary frequency
    • New-onset urinary incontinence
    • Suprapubic pain, flank pain, or abdominal pain
    • Suprapubic tenderness or CVA tenderness on physical examination
    • Nausea or vomiting
    OR

    b. For cUTI, participants must have at least 2 of the new or worsening signs and/or symptoms listed above AND must have at least 1 of the following complicating factors:

    8. Have a baseline urine culture specimen obtained within 48 hrs prior to the first dose of the study intervention. (Participants may be enrolled in this study and start i.v. study intervention therapy before the Investigator knows the results of the baseline urine culture in the event the causative pathogen is suspected to be susceptible to cefepime-enmetazobactam).
    Specimen is to be obtained by suprapubic aspiration, clean intermittent urethral catheterization, indwelling urethral catheter, or mid- stream clean catch.
    9. Likely to survive the current illness or hospitalization.
    10. Sufficient intravascular access (peripheral or central) to receive study intervention.
