Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42330   clinical trials with a EudraCT protocol, of which   6971   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    PIK3CA mutated colon cancer
    E.1.1.1Medical condition in easily understood language
    colon cancer
    E.1.1.2Therapeutic area Diseases [C] - Cancer [C04]
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The objective of the trial is to demonstrate a statistically significant and clinically relevant disease free survival benefit in stage II and III PIK3CA mutated colon cancer patients taking daily adjuvant aspirin for 3 years.
    E.2.2Secondary objectives of the trial
    Secondary endpoints of the trial are:
     Time to recurrence (TTR)
     Overall survival (OS)
     Cancer-specific survival (CSS)
     Adverse events (AEs)
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    - Tumoral expression of COX-2 (Version 1.0, 05 June 2015)
    - PI3K Downstream signaling (Version 1.0, 05 June 2015)
    - Tumoral Expression of HLA class I Antigen (Version 1.0, 05 June 2015)
    - Tumoral BRAF V600E mutations and microsatellite instability (Version 1.0, 05 June 2015)
    - Germline genetics (Version 1.0, 05 June 2015)

    The objective of the ancillary substudies of SAKK 41/13 is to explore individual patient’s tumor tissue and peripheral blood for important predictive (COX-2 overexpression by immunohistochemistry (IHC), HLA class I antigen expression, germline genetics) and prognostic (BRAF V600E mutations, tumoral MSI status) factors. This will allow to gain a comprehensive understanding of the therapeutic impact of low-dose aspirin in this group of patients. Biobanks for both tumor tissue and peripheral blood will be implemented to permit future research on colon cancer.
