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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    Evaluation of the efficacy of sodium cromolyn preservative-free ophthalmic solution compared with placebo in the prevention of symptoms of allergic conjunctivitis induced by Conjunctival Allergen Challenge (CAC) (see Appendix II) in patients with a known history of allergic conjunctivitis.
    This will be assessed through the primary endpoint, which is the itching subject’s assessment by a 5-point scale, 5 minutes after the CAC.
    E.2.2Secondary objectives of the trial
    Conjunctival hyperaemia
    Eyelid swelling
    Ocular global discomfort assessed by the subject using a Visual Analog scale 15 minutes after the study drugs instillation test.
    Comparison of tolerability of sodium cromolyn and placebo eye drops will be assessed using global assessments by subject) and reporting of Adverse Events, at visit 3.
    The subjects will stay in the Study Unit up to two (2) hours after each challenge and a phone call will be given to them 24 hours after each challenge to verify their global status.
