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   43873   clinical trials with a EudraCT protocol, of which   7292   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.

    Male and female subjects from 18 to 50 60 years of age included.
    • Subjects receiving primary primary antipsychotic therapy at a total daily dose of 2 to 6 mg of risperidone equivalents or its equivalent (as described in a Reference Document on equivalent doses of antipsychotics provided to centers).

Within this exception, the total daily dose of the second antipsychotic should not be included in the calculation of the 6 mg / day limit of the risperidone equivalent.
    • Subjects treated with a stable regimen of psychotropic drugs without clinically significant changes (no dose increase, reduction <250% of the dose due to tolerability) in the 2 months prior to the screening visit and no dose adjustment is planned for the entire duration of participation in the study up to Day 84 / Early termination visit.
    • Subjects with a total BNSS score (12 items, excluding number 4) =28; stable scores at Run-in with single-blind placebo and total BNSS (at 12 items, excluding item 4) at baseline (variation =20% compared to Screening scores).

Subjects should also have stable scores in the Single-blind and Basal placebo period (variation =20% compared to the Screening score) in all of these PANSS items.
    • Subjects with evidence of stable symptomatology =3 months prior to the screening visit (eg no admission for schizophrenia, no access to the emergency room for symptoms of schizophrenia, no increase in the level of psychiatric treatment due to worsening of symptoms of schizophrenia).
    • Subjects must have an adult informant (eg family member, social worker, social worker, protected facility personnel or nurse who spends =4 hours / week with the subject) who is deemed reliable by the investigator and is able to provide information for the compilation of the evaluation scales of the study, such as the PANSS and the SCoRS.

Il trattamento concomitante con una dose subterapeutica di un secondo antipsicotico potrebbe essere ammesso, previa approvazione dello sponsor o di un incaricato, se utilizzato come ipnotico (a un massimo di 100 mg di quetiapina o di un suo equivalente una volta al giorno prima di andare a dormire [QHS]), ma non se utilizzato per sintomi psicotici positivi refrattari. Nell’ambito di questa eccezione, la dose giornaliera totale del secondo antipsicotico non dovrà essere inclusa nel calcolo del limite di 6 mg/die dell’equivalente del risperidone.
    • Soggetti in trattamento con un regime stabile di farmaci psicotropi senza variazioni clinicamente significative (nessun aumento della dose, riduzione= <250% della dose per ragioni di tollerabilità) nei 2 mesi precedenti la Visita di screening e non è previsto alcun aggiustamento della dose per l’'intera durata di partecipazione allo studio fino al Giorno 84/Visita di interruzione anticipata.
    • Soggetti con un punteggio BNSS totale (a 12 item, escluso il numero 4) =28; punteggi stabili al Run-in con placebo a singolo cieco e BNSS totale (a 12 item, escluso l’itemil numero 4) al Basale (variazione =20% rispetto al punteggio dello Screening).

    • I soggetti devono disporre di un informatore adulto (es. familiare, operatore sociale, assistente sociale, personale della struttura protetta o infermiere che trascorra =4 ore/settimana con il soggetto) che sia ritenuto affidabile dallo sperimentatore e che sia in grado di fornire informazioni per la compilazione delle scale di valutazione dello studio, quali la PANSS e la SCoRS.
    E.4Principal exclusion criteria
    • The subject has a lifetime diagnosis of schizoaffective disorder; a lifetime diagnosis of bipolar disorder; or a lifetime diagnosis of obsessive compulsive disorder based on the MINI combined with the general psychiatric evaluation. As an exception, subjects with a historical prior lifetime diagnosis of schizoaffective disorder may be enrolled in the study with sponsor or designee approval provided that the principal investigator can attest that the subject’s overall history and current clinical presentation and history is most consistent with schizophrenia, not schizoaffective disorder.
    • The subject has a recent (within the last 6 months) diagnosis of panic disorder, depressive episode, or other comorbid psychiatric conditions requiring clinical attention based on the MINI for DSM-5 and the general psychiatric evaluation.
    • The subject has a diagnosis of substance use disorder (with the exception of nicotine dependence) within the preceding 6 months based on the MINI for DSM-5 and the general psychiatric evaluation.
    • The subject is participating in a formal structured nonpharmacological therapeutic treatment program (cognitive remediation, cognitive-behavioral therapy, intensive symptom/vocational rehabilitation) for <3 months prior to randomization. In addition, initiation of such nonpharmacological treatment programs is not permitted during study participation through the Day 84 Visit.
    • The subject exhibits more than a minimal level of antipsychotic-induced parkinsonism symptoms, as documented by a score on the modified Simpson Angus Scale (SAS) (excluding item number 10, Akathisia) >6.
