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   43851   clinical trials with a EudraCT protocol, of which   7283   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.

    At 4 weeks of treatment
    Dopo 4 settimane di trattamento
    E.5.2Secondary end point(s)
    Key Secondary Efficacy Endpoint:
    At 4 weeks of treatment, the proportion of subjects with:
    • Albumin-adjusted or ionized sCa within the normal range
    and
    • FECa within the normal range or a reduction by at least 50% from baseline and
    • Not taking active vitamin D supplements and
    • Taking =500 mg/day of calcium supplements; Other Secondary Efficacy Endpoints:
    • Primary and key secondary efficacy endpoints measured at predefined timepoints over the Extension Period. For the analysis of these endpoints in the Extension Period, the 24-hour urine calcium excretion will be used.
    At 4 weeks of treatment and at predefined timepoints over the Extension Period:
    • Calcium and vitamin D doses
    • Number of SOC supplements (pill burden)
    • Spot AM FECa
    • Serum phosphate
    • Serum magnesium
    • sCa x sP product, including proportion of subjects with sCa x sP product =55 mg2/dL2, =52 mg2/dL2, and =44 mg2/dL2
    • Albumin-adjusted or ionized sCa

    At predefined timepoints over the Extension Period:
    • 24-hour urine calcium excretion
    Endpoint secondari di efficacia
    Principali endpoint secondari di efficacia
    Dopo 4 settimane di trattamento, la percentuale di soggetti con:
    • sCa ionizzato o corretto per l’albumina entro il range della norma e
    • FECa nel range della norma o riduzione di almeno il 50% rispetto al basale e
    • nessuna supplementazione con vitamina D attiva e
    • supplementazione con calcio =500 mg/die; Altri endpoint secondari di efficacia
    • Endpoint primari e principali endpoint secondari misurati in momenti predefiniti durante il Periodo di estensione. Per l’analisi di questi endpoint nel Periodo di estensione, si userà l’escrezione di calcio nelle urine delle 24 ore.
    Dopo 4 settimane di trattamento e in momenti predefiniti durante il Periodo di estensione:
    • dosi di calcio e di vitamina D
    • numero di integratori per la supplementazione SOC (onere dei farmaci)
    • spot AM FECa
    • fosfato sierico
    • magnesio sierico
    • prodotto sCa x sP, inclusa la percentuale di soggetti con prodotto sCa x sP =55 mg²/dL², =52 mg²/dL² e =44 mg²/dL²
    • sCa ionizzato o corretto per l’albumina

    In momenti predefinitidurante il Periodo di estensione:
    • escrezione di calcio nelle urine delle 24 ore
