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.1.1Medical condition(s) being investigated
    Sickle cell anaemia is a serious inherited blood disorder where the red blood cells, which carry oxygen around the body, develop abnormally and become rigid and shaped like a crescent (or sickle)..
    Sickle Cell Disease (anemia Falciforme)
    E.1.1.1Medical condition in easily understood language
    Sickle cell anaemia is a serious inherited blood disorder where the red blood cells, which carry oxygen around the body, develop abnormally and become rigid and shaped like a crescent (or sickle).
    Anemia falciforme è un grave disturbo ematico ereditario in cui i globuli rossi che trasportano ossigeno nel corpo si sviluppano in modo anomalo e diventano rigidi e a forma di mezzaluna o falce

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to evaluate the effect of voxelotor compared to placebo on the TCD time-averaged mean of the maximum velocity (TAMMV) arterial cerebral blood flow at 24 weeks in SCD participants = 2 to < 15 years of age with conditional (170 to < 200 cm/sec) TCD flow velocity.
    L’obiettivo primario è valutare l’effetto di voxelotor rispetto al placebo sulla media ponderata per il tempo della velocità massima (TAMMV) del flusso ematico cerebrale arterioso nel doppler trascranico (TCD) a 24 settimane nei partecipanti con anemia falciforme (AF) con età compresa tra 2 e <15 anni con velocità di flusso al TCD condizionale (da 170 a <200 cm/sec)..
    E.2.2Secondary objectives of the trial
    The secondary objectives are to evaluate the effects of voxelotor compared to placebo on:
    - Change in TCD flow velocity at Week 48 and Week 96
    - Conversion of TCD category from conditional to abnormal
    - Reversion of TCD category from conditional to normal
    - Proportion of participants with TCD response
    - Change in Hb over time
    - Change in clinical measures of hemolysis
    Gli obiettivi secondari includono la valutazione degli effetti di voxelotor rispetto al placebo su:
    - Variazione nella velocità di flusso al TCD alla Settimana 48 e Settimana 96
    - Conversione della categoria TCD da condizionale ad anormale
    - Reversione della categoria TCD da condizionale a normale
    - Percentuale di partecipanti con risposta TCD
    - Variazione temporale nei livelli di Hb
    - Variazione nelle misure cliniche dell’emolisi
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Age = 2 to <15 years at the time of informed caregiver/legal guardian
    consent
    2. Male or female study participants with SCA (HbSS, HbSß0 thalassemia
