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 ).

    General information about the trial
    Main objective of the trial
    The purpose of this study was to evaluate the time to relapse after discontinuation of RLAI (Risperidone Long Acting Injection) in first- episode subjects successfully treated for 2 years with RLAI. The relapse rate after treatment discontinuation, the time to response after re-exposure to treatment with RLAI and the degree of clinical improvement measured by PANSS were also evaluated.
    Protection of trial subjects
    Safety was evaluated based on analysis of adverse events, clinical laboratory tests (hematology, serum chemistry, prolactin), vital sign measurements, electrocardiogram (ECGs), physical examinations, extrapyramidal symptoms (EPS), body weight and body mass index (BMI), and waist/hip circumference.

    Recruitment
    Recruitment details
    A total of 33 subjects entered Period 1 and discontinued their existing antipsychotic treatment. None of the subjects completed the 36-month follow-up period. A total of 31 subjects entered Period 2 and restarted Risperidone Long-Acting Injection (RLAI) treatment. Overall, 14 of the 31 subjects in Period 2 completed the 24 month treatment period.

    Pre-assignment
    Screening details
    In Period 1, existing RLAI treatment was discontinued. Subjects who experienced a relapse during Period 1 were transferred into Period 2, at which time RLAI and oral risperidone treatment was initiated simultaneously. Risperidone LAI was initiated at a dose of 25 milligram (mg) once every 2 weeks and continued for a maximum of 2 years in Period 2.

    Notes
    [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
    Justification: A total of 31 subjects entered Period 2 and restarted risperidone long-acting injection (RLAI) treatment. Two subjects in Period 1 did not enter Period 2: 1 subject who was lost to follow-up during Period 1, and 1 subject who relapsed during Period 1 but did not go on to enter Period 2 due to a positive drug screen.

The total score is the sum of all 30 PANSS items, with a range of 30 (absent) to 210 (extreme ill). Higher scores indicate worsening.

    Number of Subjects With Disease Remission Based on PANSS (Period 2)
    End point description
    A subject was 'in remission' when he/she was symptomatically stable and showed progressive improvement in total recovery according to severity (mild or less simultaneously on 8 PANSS items:P1 delusions, P2 conceptual disorganization, P3 hallucinatory behavior, G9 unusual thought content, G5 mannerisms and posturing, N1 blunted affect, N4 social withdrawal, N6 lack of spontaneity or flow of conversation) and time (scores for 8 PANSS items above did not exceed the severity criterion mild at any time point of assessment for at least 6 months to meet the criteria of remission) criteria. The efficacy analysis set included all subjects from the ITT analysis set who had at least one follow-up efficacy assessment. Disease Remission Based on PANSS was not seen till the end of period 2 (Month 24).

    End point description
    The CGI-S scale is a 7-point global assessment that measures the Clinician's impression of the severity of illness exhibited by a subject. A rating of '1=Normal, not at all ill' and a rating of '7=Among the most extremely ill subjects'. Higher scores indicate worsening. The efficacy analysis set included all subjects from the ITT analysis set who had at least one follow-up efficacy assessment.

    The CDSS assesses the level of depression in subjects with schizophrenia. It consists of 9 items: depression, hopelessness, self-depreciation, pathological guilt, guilty ideas of reference, morning depression, early awakening, suicidal, observed depression, each scored on a 4-point scale (0=absent, 1=mild, 2=moderate, 3=severe). The total score is a sum of the scores of each item and may range from 0 to 27. Higher score indicates more severe pathology. The efficacy analysis set included all subjects from the ITT analysis set who had at least one follow-up efficacy assessment.
