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   43839   clinical trials with a EudraCT protocol, of which   7280   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 ).

    Kaplan-Meier Estimate of Progression Free Survival (PFS)
    End point description
    Progression-free survival was defined as the duration from the date of randomization to the date of disease progression based on investigator’s assessment using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 or death (from any cause), whichever occurred first. Per RECIST 1.1, progressive disease (PD) was defined as at least a 20% increase in the sum of diameters of target or non-target lesions from nadir or appearance of a new lesion. The Intent-to-treat (ITT) population included all randomized participants regardless of whether the participant received any investigational product (IP) or had any efficacy assessments collected.

    Percentage of Participants who Achieved a Confirmed Complete Response (CR) or Partial Response (PR) to Treatment (Objective Response Rate) Based On the Investigator Assessment
    End point description
    Overall response rate was defined as the percentage of participants who achieved a confirmed complete response or partial response based on RECIST Version 1.1 criteria. RECIST criteria v 1.1 defined a CR as the disappearance of all target lesions and a PR with at least a 30% decrease in the sum of diameters of target lesions from baseline. The two-sided 95% exact binomial CI each arm was estimated by the Clopper-Pearson method. The Intent-to-treat population included all randomized participants regardless of whether the participant received any IP or had any efficacy assessments collected.

    Number of Participants with Treatment Emergent Adverse Events (TEAEs)
    End point description
    Treatment-emergent adverse events (TEAEs) were defined as any AEs that begin or worsen with an onset date on or after the date of the first dose of IP through 28 days after the last dose. A serious AE (SAE) = any AE which results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; constitutes an important medical event. The severity of AEs were graded based on the participant's symptoms according to the Common Terminology Criteria for Adverse Events (CTCAE, Version 4.0); AEs were evaluated for severity as follows: Grade 1 = Mild – transient or mild discomfort; no medical intervention required; Grade 2 = Moderate – mild to moderate limitation in activity; Grade 3 = Severe; Grade 4 = Life threatening; Grade 5 = Death. The safety population includes all randomized participants who received at least 1 dose of IP.
