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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    General information about the trial
    Main objective of the trial
    The main objective of the study is to determine the clinical benefit rate at 6 months. Clinical benefit is defined as the percentage of patients with complete response + partial response + stable disease. Efficacy will be determined according to RECIST V 1.0
    Protection of trial subjects
    The study was approved by an independent ethics committee according to local laws and complied with the International Conference on Harmonization Good Clinical Practice guidelines and the Declaration of Helsinki. All patients granted informed consent in writing before study entry.

    Dosage and administration details
    The patients received oral pazopanib 800 mg/day during a 28-day treatment cycle. They were allowed to receive concomitant treatment with somatostatin analogs at the investigator’s discretion. Pazopanib dose reductions were allowed as follows: level 1: 600 mg and level 2: 400 mg. Study therapy was discontinued when clinical or radiological evidence of progressive disease was documented, when a participant experienced unacceptable adverse events (AEs), withdrew consent or per investigator’s decision.

Clinical benefit rate (CBR) was defined as the percentage of patients achieving CR, PR or SD.
