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.

    		 Part B: Absolute Change From Baseline in BMI-for-age Z-score at Week 24 [10]
    End point description
    BMI was defined as weight in kg divided by height*height in m^2. z-score is a statistical measure to evaluate how a single data point compares to a standard. It describes whether a mean was above or below the standard and how unusual the measurement is, with range from -infinity to +infinity; where 0: same mean, greater than (>) 0: a greater mean, and lesser than (<) 0: a lesser mean than the standard. BMI, adjusted for age and sex, was analyzed as BMI-for-age z-score (BMI z-score). The BMI-for-age z-scores were calculated using National Center for Health Statistics growth charts. The FAS included all Part B enrolled subjects who were exposed to any amount of Part B study drug. Here “Number of subjects analysed” signifies those subjects who were evaluable for this endpoint.

    		 Part B: Absolute Change From Baseline in Weight-for-age Z-score at Week 24 [12]
    End point description
    Z-score is a statistical measure to evaluate how a single data point compares to a standard. It describes whether a mean was above or below the standard and how unusual the measurement is, with range from -infinity to +infinity; where 0: same mean, >0: a greater mean, and <0: a lesser mean than the standard. Weight, adjusted for age and sex, was analyzed as weight-for-age z-score (weight z-score). The weight-for-age z-scores were calculated using National Center for Health Statistics growth charts. The FAS included all Part B enrolled subjects who were exposed to any amount of Part B study drug. Here “Number of subjects analysed” signifies those subjects who were evaluable for this endpoint.

    Limitations and caveats
    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Due to limited sampling and instances of missing data, C4h was reported instead of Cmax as an approximation of maximum concentration. Sparse PK sampling scheme was optimized around parent compounds which limited the estimation of AUC for metabolites.
