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   43889   clinical trials with a EudraCT protocol, of which   7298   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.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is the proportion of subjects who achieve sputum
    mycobacterial culture negative for growth using the MGIT system, ie, sputum culture conversion, within 56 days. Sputum culture conversion is defined to occur at the time of the collection of a sputum specimen with mycobacterial culture negative for growth of M. tuberculosis followed by at least one additional sputum specimen with mycobacterial culture negative for growth at least 27 days after the first specimen and not followed by any sputum specimens with a mycobacterial culture positive for growth of M. tuberculosis at any point during the remainder of the 84-day trial.

    For OPC-67683, tmax, Cmax, AUC0-24h, ratios of accumulation for Cmax and AUC0-24h [Rac(Cmax) and Rac(AUC), Day 14, 28 or 56/Day 1] will be determined.
    For OPC-67683 metabolites, tmax, Cmax, AUC0-24h, Rac(Cmax) and Rac(AUC) [Day 14, 28 or 56/Day 1], and t1/2,z will be determined.

    Reported adverse events, physical examination, vital signs (blood pressure, heart rate, body temperature and weight), standard 12-lead ECG, clinical laboratory assessment results (hematology, chemistry, urinalysis).
