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   44335   clinical trials with a EudraCT protocol, of which   7366   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
    The primary objective of this study is to assess the first data on efficacy of azelastine nasal spray in SARS-CoV-2 infected patients with regards to virus load in nasopharyngeal swabs.
    Protection of trial subjects
    Symptomatic treatments for COVID-19 (e.g., analgesic drugs) have been allowed, but the following concomitant medications and procedures that might would have interfered with the clinical results werw prohibited from one months before Day 1 of the trial to Day 11: - Any nasalia including nasal lavage fluids - Any concurrent antihistamine therapies
    Background therapy
