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   44357   clinical trials with a EudraCT protocol, of which   7383   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 ).

    Number of Participants With Grade 3-5 National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 (NCI CTCAE v5.0) Bleeding/Haemorrhage [1]
    End point description
    An adverse event (AE) was any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Severity of AEs was graded using NCI CTCAE v5.0. Grade 3=Severe/medically significant but not immediately life-threatening, hospitalization/prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living; Grade 4=Life-threatening consequences, urgent intervention indicated; Grade 5=Death related to AE. Safety analysis population included all enrolled participants who had at least one full or partial administration of atezolizumab plus bevacizumab.

    ORR was defined as the percentage of participants with complete or partial response (CR or PR), as determined by the investigator according to RECIST v1.1. CR was defined as disappearance of all target lesions or any pathological lymph nodes must have reduction in short axis to < 10 mm. PR was defined as at least a 30% decrease in the SOD of all target lesions, taking as reference the baseline SOD, in the absence of CR.

    PFS was defined as the time from initiation of study treatment to the first occurrence of disease progression (PD) or death from any cause (whichever occurs first), as determined by the investigator according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1). PD was defined as at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest SOD at prior timepoints (including baseline). In addition to the relative increase of 20%, the SOD must also demonstrate an absolute increase of ≥ 5 millimeters (mm). Participants alive and without any PD were censored at the last assessment date. K-M method was used to estimate the PFS. ITT population included all participants who signed the ICF and were enrolled in the study. Number analyzed is the number of participants with data available for analysis.

    Participants self-reported symptomatic AEs using PRO-CTCAE, a validated item bank used to characterize presence, frequency of occurrence, severity, &/or degree of interference with daily function of 78 patient-reportable symptomatic treatment toxicities. PRO-CTCAE contains questions that are rated either dichotomously (for determination of presence vs. absence)/ on a 5-point Likert scale (for determination of frequency of occurrence,severity,& interference with daily function). Treatment toxicities can occur with observable signs (e.g.,vomiting)/ non-observable symptoms (e.g.,nausea). Subset of 14 symptoms most applicable to current treatments were selected for this study. Symptoms were selected based on toxicities associated with drug's class, mechanism of action, or mode of administration, & toxicities reported with drug in another indication. Participants reporting severe symptoms per the PRO-CTCAE questionnaire on Day 1 of each cycle is reported here. Safety analysis population.
