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   43871   clinical trials with a EudraCT protocol, of which   7290   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
    to assess the safety and tolerability of multiple oral (twice daily [BID]) doses of TRK-750 in oxaliplatin-treated colorectal cancer patients with chemotherapy-induced peripheral neuropathy (CIPN).
    valutare la sicurezza e la tollerabilità di dosi orali multiple (due volte al giorno [BID]) di TRK-750 in pazienti affetti da carcinoma del colon-retto trattati con oxaliplatino che presentano neuropatia periferica indotta da chemioterapia (Chemotherapy-Induced Peripheral Neuropathy, CIPN).
    E.2.2Secondary objectives of the trial
    • to assess the efficacy of multiple oral (BID) doses of TRK-750 in
    reducing neuropathic symptoms, improving quality of life (QoL), and
    clinician-reported outcomes in oxaliplatin-treated colorectal cancer
    patients with CIPN.
    • to study the relationship between plasma concentrations of TRK-750
    and safety and efficacy variables in oxaliplatin-treated colorectal cancer
    patients with CIPN.
    The exploratory objective of this study is:
    • to assess the efficacy of multiple oral (BID) doses of TRK-750 on PD
    biomarker(s) in blood, psychophysical, electrophysiological, and
    histological parameters of neuropathy in oxaliplatin-treated colorectal
    cancer patients with CIPN.
    • valutare l'efficacia di dosi orali multiple (BID) di TRK-750 nel ridurre i sintomi neuropatici e migliorare la qualità della vita (QoL) e gli esiti riferiti dal medico in pazienti affetti da carcinoma del colon-retto trattati con oxaliplatino che presentano CIPN;
    • studiare il nesso tra le concentrazioni plasmatiche di TRK-750 e le variabili di sicurezza ed efficacia in pazienti affetti da carcinoma del colon-retto trattati con oxaliplatino che presentano CIPN.
    L'obiettivo esplorativo del presente studio è il seguente:
    • valutare l'efficacia di dosi orali multiple (BID) di TRK-750 sui biomarcatori ematici farmacodinamici (PD), e sui parametri psicofisici, elettrofisiologici ed istologici della neuropatia in pazienti affetti da carcinoma del colon-retto con CIPN trattati con oxaliplatino.

    8. Pazienti con disturbi psichiatrici gravi non controllati, come depressione maggiore o psicosi.
    NOTA: saranno considerati idonei i pazienti con anamnesi di depressione o ansia stabili, trattati o meno con farmaci psichiatrici.
    9. Anamnesi di neuropatia sintomatica preesistente prima della chemioterapia, ivi inclusa neuropatia dovuta ad alcolismo, deficit di vitamina B, diabete, ipotiroidismo, virus dell’immunodeficienza umana (HIV), neuropatia congenita e neuropatia tossica. NOTA: saranno ammessi i pazienti con diabete stabile senza precedenti evidenze cliniche positive di neuropatia.

    12. Funzionalità renale inadeguata, definita come velocità di filtrazione glomerulare stimata (eGFR) = 59 ml/min, ovvero clearance della creatinina (CrCl) calcolata utilizzando l’equazione di Cockcroft-Gault con tali valori misurati nelle analisi cliniche di laboratorio eseguite allo screening:
    a. [1,23 × (140 - età) × (peso in kg)] ÷ (creatinina sierica in µmol/l) – nei soggetti di sesso maschile.
    b. [1,04 × (140 - età) × (peso in kg)] ÷ (creatinina sierica in µmol/l) – nei soggetti di sesso femminile.
    Allo screening, le analisi cliniche di laboratorio possono essere ripetute una volta.
    13. Anamnesi di abuso di sostanze entro 1 anno prima dello screening.
    14. Risultati positivi allo screening tossicologico allo Screening (confermati mediante ripetizioni) o al Giorno 1, a meno che ciò non sia in linea con l’uso del farmaco soggetto a prescrizione e approvato dallo Sponsor (o incaricato). Sarà invece motivo di esclusione incondizionata un risultato ripetutamente positivo allo screening per cocaina, fenciclidina, metadone o amfetamine per uso non medico.
    15. Risultati positivi ai test per l'antigene di superficie dell'epatite B (HBsAg), gli anticorpi contro l'epatite C (HCV) o gli anticorpi contro l'HIV allo screening. NOTA: i pazienti che risultano positivi agli anticorpi dell'epatite C possono essere idonei all'inclusione nello studio a condizione che la PCR dell'RNA degli anticorpi contro l'epatite C risulti negativa, in modo da dimostrare che l'infezione non è più in corso (o che il risultato è un falso positivo). La PCR dell'RNA dell'HCV conta come tentativo di ripetizione dello screening 16. Uso di qualsiasi farmaco in assenza di periodi di wash-out adeguati che, secondo il parere dello sperimentatore, possa influenzare il risultato dello studio o la capacità del paziente di partecipare allo studio.

    Per i parametri istologici:
    • biopsia cutanea con punch (facoltativa).
    Per i biomarcatori della neuropatia:

    La valutazione dei parametri psicofisici ed elettrofisiologici dipenderà dal centro di studio. Per i centri capaci di eseguire queste valutazioni, saranno valutati tutti i pazienti. La valutazione della farmacogenomica e dei parametri istologici sarà eseguita a esclusiva discrezione del paziente.

    The study is exploratory at this stage for patients. Patients will
    undergo a follow-up visit at the end of the study and any ongoing
    adverse events will be followed until resolution. Patients' care is the
