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 ).

    General information about the trial
    Main objective of the trial
    Part A: To determine the equivalent dose of pazopanib when taken with a continental breakfast compared to 800 mg in fasted state. Part B:To evaluate whether food can reduce the side effects diarrhea and nausea.
    Protection of trial subjects
    Part A Participating patients will be asked for a hospital admission for two days to collect the blood samples. All blood samples will be drawn from a once placed intravenous cannula. A total of 10 blood samples will be taken per admission day. the burden for the participants of this part of the study is considered to be mild. In general the risk for participation in this study is regarded moderate. The risk of suboptimal dosing is minimized by the run in of three patients at 600 mg OD with food. Benefits associated with participating in this study are that patients and their treating physician get insight into pazopanib exposure when taken with a continental breakfast. Part B The participating patients are asked to keep a record on their defecation pattern and nausea experiences during both treatment regiments, at the end of the study period their preference is asked. Therefore the burden for the participants of this part of the study is considered to be low. In general the risk for participation in this study is regarded negligible. Patient receive a bioequivalent dose pazopanib also normal Ctrhough levels will be monitored. Benefits associated with participating in this study are that patients might experience less side effects and the intake of pazopanib will be more easily incorporated in their normal life style.

    Recruitment
    Recruitment details
    This study was conducted in two parts. First, a PK study was performed to establish the bioequivalent dose of pazopanib when ingested with a CB (part 1). This part was designed as an open-label, crossover, multicenter, phase I study conducted in two centers in the Netherlands (Radboudumc (Nijmegen) and Leiden University Medical Center (Leiden).

    Pre-assignment
    Screening details
    Adult patients (≥ 18 years) receiving 800 mg pazopanib o.d. with an ECOG performance status of 0−2. The use of proton pump inhibitors was allowed when the proton pump inhibitor was used at the same time throughout the study. Use of substances known to alter Cytochrome P 3A4 metabolism were prohibited. Patients with GI abnormalities were excluded.
