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   41504   clinical trials with a EudraCT protocol, of which   6826   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives

    Other types of substudies
    Specify title, date and version of each substudy with relative objectives: 1- OCT Substudy : This sub-study explores the concept of using OCT as a structural biomarker of disease development in MS patients. The goal of
    this exploratory sub-study is to investigate the axonal degeneration in subjects enrolled into the trial, by measuring the RNFL thickness with OCT.
    2- DTI and fMRI Sub-study: This sub-study explores the concept of using DTI and fMRI as a structural biomarker of disease that are specific for brain tissue injury and repair.
    The goal of this exploratory sub-study is to investigate the brain structural and functional changes in subjects enrolled into the trial, by measuring DTI and fMRI over time.
    3 CSF Biomarker Sub-study: Validated biomarkers will help to define an optimal cladribine treatment response in MS and thus be of considerable
    value for taking treatment decisions and ensuring continued benefit from cladribine therapy. The candidate biomarkers have been selected
    on basis of evidences from literature.
    The goal of this exploratory sub-study is to investigate the surrogate marker in subjects enrolled into the trial, by measuring CSF biomarkers over time.
    4- Blood Biomarker Sub-study
    The goal of this exploratory sub-study is to investigate the surrogate marker in patients enrolled into the trial, by measuring blood biomarkers over time.

    Altre tipologie di sottostudi
    specificare il titolo, la data e la versione di ogni sottostudio con i relativi obiettivi: 1 - Sottostudio di tomografia ottica computerizzata OCT: questo sottostudio esplora il concetto dell’utilizzo di OCT come biomarker strutturale dello sviluppo della malattia nei pazienti affetti da SM. L’obiettivo di questo sottostudio esplorativo è di valutare la degenerazione assonale nei soggetti arruolati nella sperimentazione, misurando lo spessore dello strato di fibre nervose retiniche [RNFL] – spessore maculare con OCT.
    2- Sottostudio di imaging con tensore di diffusione (DTI) e RMI funzionale (fMRI): questo sottostudio esplora il concetto dell’utilizzo di DTI e fMRI come biomarker strutturali della malattia che sono specifici per le lesioni cerebrali e la riparazione.
    L’obiettivo di questo sottostudio esplorativo è di studiare i cambiamenti strutturali e funzionali a livello cerebrale nei soggetti arruolati nella sperimentazione, con valutazioni di DTI e fMRI ripetute nel tempo.
    3. Sottostudio sui biomarcatori dell’LCS (liquido cerebrospinale): Biomarkers validati aiuteranno a definire la risposta ottimale per la SM al trattamento con cladribina e saranno quindi di considerevole valore per prendere decisioni relative al trattamento e per assicurare il continuo beneficio della terapia con la cladribina. I biomarkers candidati sono stati selezionati sulla base di evidenze dalla letteratura.
    4. Sottostudio sui biomarcatori del sangue:
    L’obiettivo di questo sottostudio esplorativo è di studiare i marker surrogati nei pazienti arruolati nella sperimentazione.
