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   43870   clinical trials with a EudraCT protocol, of which   7289   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 this trial was to gain first insights into the effects of pre-, peri- and postoperative cannabinoid intake on the physical and psychological coping with surgery as well as on the pain perception of patients with severely reduced quality of life.
    Protection of trial subjects
    Throughout the study all involved investigators adhered to the law as laid down in the European Regulation (EU) 2016/679 as well as to the national data protection law. Safety Assessments Tolerability was described through the: number of subjects (%) who discontinue the study and the number of subjects (%) who discontinue the study due to AE safety measures included the following: AEs, SAEs, SUSARs, clinical and laboratory assessment, vital parameters (oxygenation, heart rate and blood pressure during surgery), patients' compliance and medication use (prior for relevant medication, concomitant).
    Background therapy
    All subjects enrolled in the study underwent elective spinal fusion surgery in 1-2 segments for spinal degeneration.

    Recruitment
    Recruitment details
    Study participants were recruited among the patients planned for spinal fusion surgery (one to max. two segments) at the orthopedic hospital Speising. To avoid falsification of population representation and by ethical concerns, there was not any pre-selection performed (e.g. by social status, etc.) before checking inclusion criteria.

    Pre-assignment
    Screening details
    Screening Criteria: - elective spinale fusion surgery (1-2 segments) - >18 years Approx. 500 people screened Reasons for excluding: - Participation in another trial - Expected drop out due to hospital-hometown-distance
