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   43976   clinical trials with a EudraCT protocol, of which   7312   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
    Assess the effect of azithromycin on cough measured using automated cough counting
    Protection of trial subjects
    The investigator or designee will question subjects about AEs and intercurrent illnesses at Baseline and at all subsequent visits since their last visit. The pertinent information will be recorded on the CRF. Safety will be assessed through monitoring of adverse events/serious adverse events of special interest, physical examinations, vital signs, and 12-lead ECGs. Safety assessment frequency is shown in the Schedule of Assessments and Procedures Robust consent process in place.

    The Screening/baseline visit will ensure that each subject meets all the specified inclusion criteria and none of the exclusion criteria. Once consented, the Hull Automated Cough Counter will be given to the patient with verbal and written instructions. The initial supply of study drug (azithromycin 250mg once daily) will be issued, with written instructions to take the first dose on the day after completing the cough counting. The subject will return the cough counter for analysis at their convenience.
