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
    To test the benefits of oral Tocovid SupraBio (tocotrienols) with pentoxifylline (PTX) in patients suffering chronic gastrointestinal adverse effects following curative pelvic radiotherapy for cancer.
    Protection of trial subjects
    There are no reported side-­effects of tocotrienol at the doses prescribed for the study, and no pain or distress due to trial participation was expected/experienced
    Background therapy

    Evidence for comparator
    Treatment group Tocovid SupraBio 200mg po bd plus pentoxifylline (PTX) 400mg po bd for 12 months Control group Matching placebos po bd for 12 months The primary endpoint was change at 12 months in the bowel disease subset of the Modified IBDQ Quality of Life questionnaire. As this is a subjective patient self-assessment, we chose placebo tablets as comparators to the active drugs.

    Blinding implementation details
    Treatment allocation was in a 2:1 ratio of Tocovid SupraBio+PTX:Matched placebo and was based on computer generated random permuted blocks (of block sizes 6 and 9). Randomisation was stratified by the severity of their symptoms (IBDQ-B≥60 vs. IBDQ-B<60) and average daily fat intake (≥90g fat/day vs. <90g fat/day). All IMPs including placebos were packaged, labelled and dispatched to investigator site as open label supplies. Pharmacy were unblinded in the study as was one internal monitor.

    Adverse events of any grade are reported by treatment group regardless of assesment of relatedness to treatment. If the same preferred term is reported for a patient twice with the same start date or with over-lapping start and end dates these are counted as a single event.
