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   43851   clinical trials with a EudraCT protocol, of which   7283   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. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Individuals with moderate to severe depression according to ICD-10 criteria.
    MedDRA Classification
    E.1.2 Medical condition or disease under investigation
    E.1.2Version 8.1
    E.1.2Level LLT
    E.1.2Classification code 10012378
    E.1.2Term Depression
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary object of this trial is to estimate the effect of folate augmentation in new or continuing treatment of depressive disorder in primary and secondary care.
    E.2.2Secondary objectives of the trial
    Secondary objectives are to evaluate the cost-effectiveness of folate augmentation of antidepressant treatment, investigate how the response to antidepressant treatment depends on genetic polymorphisms relevant to folate metabolism and antidepressant response, and explore whether baseline folate status can predict response to antidepressant treatment.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Translation and Validation study of a Welsh Language Version of the Beck Depression Inventory-II. 22nd June 2008 Version 3

    Objective: To translate and validate the Welsh Language Version of the Beck Depression Inventory-II (BDI-II). This sub-study will involve inviting Welsh speaking participants to complete the Welsh Language version of the BDI-II at the end of the randomisation appointment (second visit). This study aims to test the Welsh language version to make sure it measures symptoms of depression as well as the English Language version.
    E.3Principal inclusion criteria
    Only patients aged 18 or over with an ICD-10 diagnosis of moderate to severe depression [confirmed by the trial psychiatrists during the screening interview using the Beck Depression Inventory (BDI)] will be included. Only patients able to give informed consent (not delirious, actively psychotic or with severe communication or learning disability) and able to complete the research assessments will be included.
    E.4Principal exclusion criteria
    Patients will be excluded from the study if they
    (a) are folate deficient:they cannot be randomised because they need to be treated with folic acid but can be included in the comprehensive cohort
    (b) are B12 deficient: they cannot be randomised because they need to be treated with B12 injections but can be included in the comprehensive cohort
    (c) have knowingly taken supplements containing folic acid within 2 months because this will mask any effects of folic acid given during the study
    (d) suffer from psychosis because additional treatment for psychosis may mask any benefit of folic acid with antidepressants. Plus people suffering from psychosis are less able to give informed consent and will require referral through to secondary services.
    (e) suffer from bipolar disorder
    (f) are already participating in another research project
    (g) are pregnant or planning to become pregnant as it is important for pregnant women to take folic acid so they cannot be randomised to placebo
    (h) are taking anticonvulsants as in very rare circumstances folic acid can react with certain anticonvulsants
    (i) serious, advanced or terminal illness with a life expectancy of less than 1 year
    (j) have recently started treatment for a medical condition which has not yet been stabilised
    (k) have had a diagnosis or treatment for any malignant disease or any related condition such as intestinal polyposis
    E.5 End points
    E.5.1Primary end point(s)
    The primary end point is to demonstrate a significantly meaningful difference on the Beck Depression Inventory (BDI) for individuals taking folic acid 5mg as a supplement to antidepressant therapy over and above that observed for those taking the placebo.
