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   43974   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
    The purpose of this study was to compare Olopatadine Hydrochloride (HCl) Nasal Spray 0.6% and Olopatadine HCl Nasal Spray Vehicle when given twice daily (BID) for the treatment of Seasonal Allergic Rhinitis (SAR) for a 2-week period.
    Protection of trial subjects
    Prior to the start of the study, the study protocol, the informed consent and assent documents, patient instruction sheets, the Investigator’s Brochure, as well as any advertising materials used to recruit patients were submitted to institutional review boards (IRBs) and independent ethics committees (IECs). The IRB/IECs reviewed all documents and approved required documents; copies of the approval letters were provided to Alcon. Consistent with both the IRB/IEC’s requirements and all applicable regulations, the Investigators periodically provided study updates to the IRB/IEC. A patient or parent/legal guardian (if necessary, a legally authorized representative) provided informed consent, and children signed an approved assent form when appropriate. This study was conducted in accordance with Good Clinical Practices (GCP) and the ethical principles that have their origins in the Declaration of Helsinki.

    Percent Change from Baseline in rTNSS
    End point description
    The rTNSS was defined as the average of the AM and PM reflective (how the subject felt for the last 12 hours) severity scores for the sum of assessments of runny nose, stuffy nose, itchy nose, and sneezing, averaged across the first 14 complete days of the randomized treatment phase. Symptoms were evaluated twice daily while on study therapy via a subject telephone diary and rated on a 4-unit scale, where 0=none, 1=mild, 2=moderate, and 3=severe. A more negative change number indicates improvement, namely lessening of the symptom.
