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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    E.5 End points
    E.5.1Primary end point(s)
    Pathological complete response of breast and lymph nodes (ypT0/is ypN0).
    Pathologische Komplettremission von Brust und Lymphknoten (ypT0/is ypN0).
    E.5.1.1Timepoint(s) of evaluation of this end point
    Pathological response will be assessed considering all removed breast and lymphatic tissues from all surgeries. Surgery takes place shortly after the 30 weeks treatment.
    Das pathologische Ansprechen wird anhand aller bei der Operation entnommenen Brust- und Lymphgewebeproben analysiert. Die Operation findet unmittelbar nach der Therapiephase von 30 Wochen statt.
    E.5.2Secondary end point(s)
    Secondary endpoints:
    Other pCR definitions (ypT0 ypN0; ypT0 ypN0/+; ypT0/is ypN0/+) ypTany ypN0, regression grade according to Sinn, response by physical examination, imaging response, breast conservation) will also be summarized as rates in the treatment group, two-sided 90% confidence intervals will be calculated according to Pearson and Clopper, these tests are considered explorative.
    Clinical and imaging response will be assessed in the last week of the 6 weeks treatment period without chemotherapy and before surgery by physical examination and imaging tests. Sonography is the preferred examination, however, if sonography appears not to provide valid results or is not performed, other imaging tests will be considered with the following priority: MRI, mammography, computed tomogram. The same imaging method should be considered for the measurement before and after treatment.
    For defined categories of efficacy (complete, partial, stable, or progression), the proportion of patients with success will be determined and appropriate confidence intervals will be calculated.
    Patients in whom success cannot be determined (e.g. patients in whom histology is not evaluable) will be included in the denominator, i.e. these patients will affect the success rate in the same way as treatment failures. The clinical tumor response by palpation prior to surgery will also be presented, if applicable.
    Breast conservation rate: All breast conserving surgeries (tumorectomies, segmentectomies, quadrantectomies) without reconstruction are summarized as rates.
    Tolerability and Safety: Descriptive statistics will be given on the number of patients whose treatment had to be reduced, delayed or permanently stopped. The reason for termination includes aspects of efficacy (e.g. termination due to tumor progression), safety (e.g. termination due to adverse events) and compliance (e.g. termination due to patient's withdrawal of consent). Reasons for premature termination will be categorized according to the main reason and will be presented in frequency tables. Safety by toxicity grades are defined by the NCI-CTCAE version 4.0.
    Translational research: Exploratory analyses will be performed to identify possible relationships between biomarkers and drug activity. The aim is to identify potential predictive parameters for sensitivity or resistance (pCR, no treatment effect according to regression score 0-1 according to Sinn). Missing data on response evaluation will be set to no response.
    Andere pCR-Definitionen (ypT0 ypN0, ypT0 ypN0/+, ypT0/is ypN0/+) ypT-jede ypN0, Regressionsgrad nach Sinn, Ansprechen anhand körperlicher Untersuchungen, Bildgebung, Brusterhaltung werden ebenso als Raten in jeder Behandlungsgruppe zusammengefasst, ein zweiseitiges 90%-Konfidenzintervall wird nach Pearson und Clopper berechnet, diese Tests sind als explorativ zu betrachten.
    Das klinische und bildgebende Ansprechen wird in der letzten Woche der sechswöchigen Behandlungsdauer von Afatinib und Trastuzmab und vor der Operation durch körperliche und bildgebende Untersuchungen beurteilt. Die Sonographie ist die bevorzugte Untersuchung, falls sie jedoch keine validen Ergebnisse liefert oder sie nicht durchgeführt worden ist, werden andere bildgebende Verfahren mit folgender Priorität herangezogen: MRT, Mammographie, CT. Dabei sollte dasselbe bildgebende Verfahren bei der Messung vor und nach der Therapie angewendet werden.
    Für definierte Kategorien von Wirksamkeit (Komplettremission, partielle Remission, stabile Erkrankung oder Progress) wird der Anteil der Patientinnen ermittelt und entsprechende Konfidenzintervalle berechnet.
    Patientinnen, bei denen kein Ansprechen bestimmt werden kann (wenn z.B. histologische Befunde nicht auswertbar sind), werden in die Berechnung einbezogen, d.h., diese Patientinnen beeinflussen die Erfolgsrate in der gleichen Weise wie das Versagen der Behandlung. Das klinische Ansprechen des Tumors durch Palpation vor der Operation wird, falls zutreffend, ebenfalls ermittelt.
    Rate der Brusterhaltenden Therapie: Alle brusterhaltenden Operationen (Tumorektomie, Segmentektomie, Quadrantektomie) ohne Rekonstruktion werden als Rate zusammengefasst.
    Verträglichkeit und Sicherheit: Deskriptive Statistiken werden für die Anzahl der Patientinnen erstellt, deren Medikamentengabe reduziert, verschoben oder dauerhaft abgebrochen werden musste. Gründe für einen Abbruch umfassen Wirksamkeit (z.B. Abbruch aufgrund eines Tumor-Progresses), Sicherheit (z. B Abbruch wegen unerwünschter Ereignisse) und Compliance (z.B. Abbruch aufgrund des Widerrufs der Einverständniserklärung durch die Patientin). Gründe für einen vorzeitigen Abbruch werden nach Hauptgründen kategorisiert und in Häufigkeitstabellen dargestellt. Die Sicherheit gemäß Toxizitätsgraden wird anhand der NCI-CTCAE Version 4.0 definiert.
    Translationale Forschung: Es werden Analysen durchgeführt, um mögliche Zusammenhänge zwischen Biomarkern und der Wirksamkeit der Medikamente zu ermitteln und potentiell prädiktive Sensitivitäts- bzw. Resistenzmarker zu identifizieren (pCR, kein Behandlungseffekt gemäß Regressionsgrad 0-1 nach Sinn). Fehlende Daten bei der Evaluation des Ansprechens werden als „kein Ansprechen“ definiert.
