Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   36095   clinical trials with a EudraCT protocol, of which   5934   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To compare neurocognitive effects of amisulpride with those of risperidone in patients with chronic schrizophrenia, as assessed by the general cognitive index, a measure of overall cognitive functioning in schrizophrenia
    E.2.2Secondary objectives of the trial
    Secondary analyses: how the two atypical agents’ neurocognitive effects compare with regard to their profile of therapeutic action; Investigate whether amisulpride elicits more improvement on negative symptoms compared to risperidone treatment, as measured by the total score on the SANS 8 and by the Negative Symptom Subscale of the PANSS; Assess whether amisulpride improves overall functioning and individual domains of psychotic symptoms compared to risperidone as measured by the Clinical Global Impression (CGI), and the total and positive and general psychopathology subscale scores of PANSS and by the individual domains of SANS, respectively; Evaluate the safety and tolerability of amisulpride and risperidone based on the study completion rates, and frequency of abnormal laboratory values, prolactin serum concentrations and on the Simpson Angus Scale for Extrapyramidal Symptoms (SAS) 10 and the Abnormal Involuntary Movement Scale (AIMS).

    Overall Clinical Effects: Clinical Global Impression (CGI).

    Clinical Symptoms/Ratings of psychopathology: The total and each of the subscale scores on the PANSS (positive and negative symptoms, general psychopathology), and the SANS (Attention; Affect; Alogia, asociality/Anhedonia; Avolition).
