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   44351   clinical trials with a EudraCT protocol, of which   7378   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.

    Overall Response Rate (ORR) by the Investigator [1]
    End point description
    ORR was defined as the percentage of participants with the best overall confirmed response of complete response (CR) or partial response (PR) according to the appropriate response assessment criteria including Response Evaluation Criteria in Solid Tumors (RECIST 1.1) or Response Assessment in Neuro-Oncology (RANO) for the disease setting as assessed by the Investigator. CR or PR was confirmed at a subsequent scan (>=4 weeks) if the criteria for each are met. The exact 95% confidence intervals (CIs) were calculated using Clopper-Pearson method. Efficacy Analysis Set comprises of all participants who received at least one dose of study drug and have measurable disease as determined by the Investigator at baseline.

    End point title
    Number of Participants With Treatment Emergent Adverse Events (TEAEs)
    End point description
    An adverse event (AE) is any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to study intervention. A serious adverse event (SAE) is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment. An AE is considered to be treatment-emergent if it has a start date/time on or after first administration of study drug until 30 days after last dose of study drug and before the start of subsequent therapy, whichever comes earlier. The distribution of AEs was analyzed by the type, frequency and severity for TEAEs. Safety Analysis Set has of all patients enrolled in the study who receive at least one dose of study drug.

    Number of Participants With Worst Case Hematology Results by Maximum Grade Increase Post-baseline Relative to Baseline
    End point description
    Blood samples were collected for the analysis of following hematology parameters: anemia, neutrophil count decreased and white blood cell decreased. Grade 1 (G1): mild; Grade 2 (G2): moderate; Grade 3 (G3): severe; Grade 4 (G4) life-threatening or disabling. Higher grade indicates greater severity and an increase in Common Terminology Criteria for Adverse Events (CTCAE) grade was defined relative to the Baseline grade. Any worst-case post baseline increase to G2, G3, and G4 are presented. The laboratory parameters were graded according to CTCAE version 5.
