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   43874   clinical trials with a EudraCT protocol, of which   7293   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 ).

    General information about the trial
    Main objective of the trial
    To provide estimates of the effectiveness of the study medication, amlodipine, to inform a calculation for a larger more definitive study. We hypothesise that the amlodipine addition (augmentation) to a patients routine treatment will lead to significantly more people achieving remission (a lessening of their symptoms) at 16 weeks when compared with those patients who have the placebo augmentation. This is however a pilot study and as such is not expected to have sufficient numbers of participants to provide definitive proof of this.
    Protection of trial subjects
    The questionnaires and instruments used for this study asked questions of the patient that could be upsetting by their very nature of asking questions about the patient’s mental state, feelings of guilt, cognition, hallucinations, thoughts of suicide, sexual performance and the impact of the patient’s depression and its possible affects on their daily lives. While all of this information is requested to permit a full understanding of the disease and to permit a measure if there are differences between the arms of this study, it is possible that the patient could become upset by the questions and their answers. The staff working on the study are experienced members of the research team with a great understanding of the disease and how it affects the patients’. Every care was taken to explain the requirements of the questionnaires and their importance while being sensitive and supportive to the patient and the carer. Support was provided through routine care in line with local policy to manage any particular concern that could be raised during the course of the study.

    Recruitment
    Recruitment details
    Subjects were identified by searching Quality Outcome Framework long term illness databases for people over 50 who were on antidepressant medication, which shows that patients have been assessed as having a depressive illness which needs more than watchful waiting or counselling.

    Pre-assignment
    Screening details
    Potential participants were identified by screening computerised records in primary care, and secondary care. Local primary care practices were identified in Newcastle and Gateshead through the PCRN and NTW CLRN. Staff at these practices conducted computerised screening and sent out letters to potential study subjects using support from the PCRN/CL

    Blinding implementation details
    Randomisation was conducted by the Newcastle Clinical Trials Unit (NCTU) web-based system in a 1:1 ratio stratified by severity (defined by a dichotomous variable indicating whether baseline HAM-D was less than or greater than or equal to 15) and the treatment allocation was kept blind from the subjects and the study assessors and investigators until study completion.

    Summary Statistics
    Statistical analysis description
    In total, of the 206 invited patients, 8 were recruited into the study. Rate = 8/206 = 3.9% (95% CI: 1.7 to 7.5%). As a result of this small sample size the analysis plan was altered from that described in the protocol. There was no comparative hypothesis testing and instead summary statistics were calculated for pre-specified outcome variables by arm. Study compliance was assessed in both group as well as remission rates. None of the patients achieved remission at any point in the study.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    06 Mar 2013
    Extra exclusion criteria
    04 Jul 2013
    Amendment 10 was a change to the exit strategy. Following a meeting of the DMEC, the committee agreed that unblinding the patients prior to study completion and data analysis may cause bias within the study due to associated unblinding of study staff. Unfortunately an internal error within CSP caused a delay in this amendment being approved by the Newcastle upon Tyne Hospitals NHS Foundation Trust. By the time that the approval came through, all patients had completed the trial and therefore consented to the earlier version of the PIS. 5 of the 8 participants requested to be unblinded in total.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
