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   43861   clinical trials with a EudraCT protocol, of which   7284   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
    The primary objective of this trial is to evaluate the benefits and risks of a supported programme of antipsychotic dose reduction, and where feasible discontinuation, in adults with multiple episode schizophrenia and psychotic disorders. These benefits and risks will be established in comparison to a control group from the same clinical population who will maintain their current antipsychotic regimen.

    The hypothesised principal outcome of the trial is that the programme of reduction will improve the social functioning of participants without increasing the risk of having a severe relapse.

    The principal secondary outcome will be severe relapse. Other secondary outcomes include quality of life, neuropsychological function, side effects and employment rates.
    E.2.2Secondary objectives of the trial
    The secondary objective of this trial is to evaluate participants' and professionals' experiences of the antipsychotic reduction programme. This qualitative evaluation of process will explore programme impact, acceptability and satisfaction and is necessary to inform subsequent implementation of the programme if it is found to be effective.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Aged over 18 years
    2. A clinical and/or ICD10 diagnosis of schizophrenia, schizoaffective disorder, delusional disorder or other non-affective psychosis
    3. More than one previous episode of relapse or psychotic exacerbation, or a single episode lasting more than one year
    4. Taking antipsychotic medication
    E.4Principal exclusion criteria
    1. Participant lacks capacity to consent to the trial
    2. Participant has insufficient command of spoken English to understand trial procedures
    3. Participant subject to a Community Treatment Order (CTO) that includes a requirement to take antipsychotic medication
    4. Clinician considers there will be a serious risk of harm to self or others
    5. Participant has been admitted to hospital or had treatment from the Home Treatment or Crisis Team within the last month
    6. Females who have a confirmed pregnancy
    7. Females who are breast-feeding
    8. Involvement in another IMP trial
    9. No contraindications to continuing on antipsychotic medication
    E.5 End points
    E.5.1Primary end point(s)
    The primary outcome is social functioning, as measured by the Groningen Social Disability Schedule (GSDS) (Wiersma et al, 1988) at 2 year follow-up.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The end point is an assessment at 24 months after randomisation.
    E.5.2Secondary end point(s)
    The principal secondary outcome will be severe relapse, which will be assessed for the duration of the study period.

    Other secondary outcomes will be:
    • Rates of functional recovery defined by categorising GDSD scores• Symptoms as measured by PANSS
    • Subjective quality of life as measured by the MANSA
    • Adverse effects of antipsychotics measured by a modified version of the Glasgow Antipsychotic Side-effect Scale
    • Body weight
    • Sexual dysfunction as measured by the ASEX
    • Employment
    • Neuropsychological function (measured by a brief battery of tests designed for this trial)
    • Economic analysis

    Local clinicians will be trained to administer the antipsychotic reduction intervention strategy and can continue to apply it after the study has finished if participants want this and study results suggest it is useful.
