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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).

    Clinical Trial Results:
    A randomised, placebo-controlled, double-blind trial of the antidepressant efficacy of a novel CNS-penetrant P2X7 receptor antagonist, JNJ-54175446, in people with major depressive disorder, an incomplete response to monoaminergic antidepressant drugs, and a biomarker profile predictive of active P2X7 signalling.

    General information about the trial
    Main objective of the trial
    The principal research objective is to evaluate whether a new anti-inflammatory drug, called JNJ-54175446, is effective in treating depressive symptoms in patients with major depressive disorder. This drug works by blocking a receptor called P2X7 which is known to cause brain inflammation in response to stress. We predict that blocking P2X7 will be beneficial for depressed patients who have not responded completely to standard anti-depressant drugs and who have blood test results at screening which indicate high levels of P2X7 activity. Effectiveness will be measured using a standard clinical depression scale, called MADRS, after 8 weeks of treatment, and we will test the hypothesis that there is significantly greater improvement of depression in the patients treated with JNJ-54175446 compared to the patients treated with placebo.
    Protection of trial subjects
    The trial has an Independent data monitoring committee (IDCM) and this is independent of the investigators, the trial team and the NIMA consortium. The roles, membership and frequency of meetings are described in the IDCM charter. Briefly the IDCM is responsible for reviewing all safety data including clinical laboratory data, adverse events and special reporting situations. The IDCM makes recommendations to the TSC. The IDCM meets annually

    Trial participants, coordination and site staff including site pharmacists are blinded to the treatment during the duration of trial. Participants are assigned to one of two treatment groups (active drug or placebo) via a web-based randomisation system. Each participant is assigned a unique kit number held at the trial site. The trial statistician will be unblinded for the purpose of safety data reporting to IDMC.

    Trial participants, principal investigators and other site staff including pharmacist were blinded to the treatment group during the duration of the trial. The physical appearance of the IMP is matched by the placebo and both were presented in identical packaging. Upon randomisations each participant is allocated to a kit number by the web-based randomisation systems (sealed envelope). The concealment codes were maintained within the web-based system.

    MADRS score [1]
    End point description
    The Montgomery Asberg Depression Rating Scale (MADRS) is a researcher-rated scale designed to measure depression severity and detects changes due to antidepressant treatment. The test consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total score of 60. Higher scores represent a more severe conditions.
    End point type
    Primary
    End point timeframe
    MADRS score is taken at baseline and end of treatment at week 8. The primary endpoint will be the difference between the MADRS score taken at baseline and at end of treatment at week 8.
    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: Due to the small number of participants recruited to the trial prior to its premature termination, no statistical analysis was possible.

    Interruptions (globally)

    Were there any global interruptions to the trial? Yes
    Date
    Interruption
    Restart date
    10 Jun 2022
    The trial was terminated early due to the IMP supplier, Janssen, no longer supporting the trial. The IMP (JNJ-54175446) was supplied by Janssen to the distributor in bulk rather than in bottles for distribution to each trial site. Th cost of bottling the IMP by the distributor was considered too expensive by Janssen and they decided to withdraw their support for the trial. As the available supply of IMP at each site expired on 12 June 2022 with no ability to extend the expiry date, the trial had to terminate prematurely having recruited only 15 participants.
    -

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    As the trial terminated prematurely with only 15 out of the planned 142 participants recruited, there are no sufficient data to conduct a statistical analysis and evaluate safety and efficacy of the IMP.
