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   44341   clinical trials with a EudraCT protocol, of which   7370   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.

    End point description
    HbA1c is the glycosylated fraction of hemoglobin A. It is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. Least Squares (LS) mean was determined using Analysis of Covariance (ANCOVA) model treatment + country + CGM use prior to study entry [yes/no]+ carbohydrate counting for prandial insulin[yes/no] + baseline value of the dependent variable (Type III sum of squares) as variables. Missing data at Week 26 were imputed by return-to-baseline multiple imputations approach. APD: All randomized participants who received at least one dose of the study drug and had HbA1c measurement at baseline or Week 26. Participants who discontinued the study drug due to inadvertent enrollment were excluded.

    Change from Baseline in Fasting Blood Glucose
    End point description
    Change from baseline in fasting glucose measured by self-monitoring blood glucose (SMBG). LS mean was determined using ANCOVA model with treatment, country, CGM use prior to study entry [yes/no], carbohydrate counting for prandial insulin dosing [yes/no]) and baseline value of the dependent variable as variables. Missing data at Baseline were imputed with multiple imputation with assumption of missing at random. Missing data were imputed by return-to-baseline multiple imputations approach. APD: All randomized participants who received at least one dose of the study drug and had evaluable data for this outcome at Baseline, Week 26, or Week 52 were included in the analysis. For the Week 26 analysis, data from Baseline or Week 26 were considered, while for the Week 52 analysis, data from Baseline or Week 52 were included. Participants who discontinued the study drug due to inadvertent enrollment were excluded.

    Percentage of time spent in the hypoglycemia range with blood glucose < 54 mg/dL (3.0 mmol/L), as measured during the CGM session over a 24-hour period from week 23 to week 26 and week 49 to week 52 was reported. LS Mean was determined by ANCOVA model using treatment + country + CGM use prior to study entry [yes/no] + carbohydrate counting for prandial insulin dosing [yes/no] + Hemoglobin A1c Stratum at Baseline and baseline value of the dependent variable (Type III sum of squares). as variables. Missing data at Baseline were imputed with multiple imputation with assumption of missing at random. Missing data at week 23-week 26 and week 49-week 52 were imputed by return-to-baseline multiple imputations approach. APD: For the Week 23-26 analysis, data from Baseline or Week 23-26 were considered, while for the Week 49-52 analysis, data from Baseline or Week 49-52 were included. Participants who discontinued the study drug due to inadvertent enrollment were excluded.

    Diabetes Treatment Satisfaction as Measured by the Diabetes Treatment Satisfaction Questionnaire, Change Version (DTSQc) at Week 26
    End point description
    The DTSQc score is used to assess relative change in participant satisfaction from baseline. The questionnaire consists of 8 items, 6 of which measure Treatment Satisfaction, dealing with: 1. satisfaction with current treatment; 2. convenience of the treatment; 3. flexibility; 4. satisfaction with own understanding of participant's diabetes; 5. how likely to recommend their present treatment; and 6. how satisfied to continue with their present treatment. Each item is rated on a 7-point Likert scale (which ranges from -3 (much less satisfied) to +3 (much more satisfied). The scores from the 6 treatment satisfaction items are summed to a Total Treatment Satisfaction Score, which ranges from -18 (much less satisfied) to +18 (much more satisfied). Higher the score the greater the improvement in satisfaction with treatment. The lower the score the greater the deterioration in satisfaction with treatment.

    Change From Baseline in Short Form-36 Version 2 (SF-36 v2) Acute Form (Physical-Component and Mental-Component) Scores
    End point description
    The SF-36v2 is a participant-reported measure designed to assess health status using 36 items across 8 domains: Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health. The 8 health domains are aggregated into two summary scores known as the physical component summary (PCS) score and the mental component summary (MCS) score. Scoring of each domain and both summary scores are norm based and presented in the form of T-scores, with a mean of 50 and a standard deviation of 10. Higher scores indicate better levels of function and/or better health. Range cannot be specified in norm-based scores. LS Mean was determined by MMRM model with Baseline + Country + Carbohydrate counting for Prandial Dose + Prior CGM use + Hemoglobin A1c Stratum at Baseline + Treatment + Time + Treatment*Time (Type III sum of squares). as variables. Unstructured variance-covariance structure was used.
