Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   35504   clinical trials with a EudraCT protocol, of which   5838   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).
     
    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 was to compare the efficacy of 2 doses of quetiapine (400 mg/day and 800 mg/day) with that of placebo in the treatment of schizophrenia in adolescent patients as assessed by the change from baseline to Day 42 in the Positive and Negative Syndrome Scale (PANSS) total score (primary outcome variable).
    Protection of trial subjects
    The final study protocol, including the final version of the Informed Consent Form (ICF), was approved or given a favorable opinion in writing by an Institutional Review Board (IRB) or Independent Ethics Committee (IEC) as appropriate. The Principal Investigator was responsible for informing the IRB or IEC of any amendment to the protocol in accordance with local requirements. The Principal Investigator was also responsible for providing the IRB with reports of any serious adverse drug reactions from any other study conducted with the investigational product. Progress reports and notifications of serious adverse drug reactions were provided to the IRB or IEC according to local regulations and guidelines. The study was performed in accordance with the ethical principles that have their origin in the Declaration of Helsinki and are consistent with Internation Conference on Harmonization (ICH)/Good Clinical Practice (GCP) and applicable regulatory requirements and the AstraZeneca policy on Bioeithics. The Principal Investigator at each center ensured that both the patient (assent) and the parent or legal guardian (consent) were given full and adequate oral and written information about the nature, purpose, possible risk and benefit of the study.

    Recruitment
    Recruitment details
    This multicenter study was conducted between 1 October 2004 and 20 June 2007. 268 patients were enrolled from one of 43 international centers

    Pre-assignment
    Screening details
    This study had a 28 day washout period and a 6-week double-blind treatment period where patients were randomized to quetiapine 400 mg/day, 800 mg/day or placebo.

    Pre-assignment period milestones
    Number of subjects started
    268 [1]
    Number of subjects completed
    222

    Pre-assignment subject non-completion reasons
    Reason: Number of subjects
    Protocol deviation: 42
    Reason: Number of subjects
    Patient Moved: 2
    Reason: Number of subjects
    Adverse event, non-fatal: 2
    Notes
    [1] - The number of subjects reported to have started the pre-assignment period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: The number of subjects reported to have started the pre-assignment period is 268, which includes 46 patients who were initially found eligible but were not enrolled into the study. The worldwide number enrolled in the trial is 222 which is the number of subjects who were actually entered into the study.
