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.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Provision of written informed consent.
    2. Histological or cytological confirmation of colorectal adenocarcinoma (excluding appendiceal and anal canal cancers, as well as colorectal cancers of mixed histologies [e.g., mucinous adenocarcinoma, micropapillary, signet-ring cell carcinoma]) that is unresectable and/or metastatic.
    3. Measurable disease (as defined by RECIST v1.1).
    4. Received ≥2 months of a first-line fluoropyrimidine and oxaliplatin-containing regimen for metastatic disease or relapsed within 6 months of completing a fluoropyrimidine and oxaliplatin-containing adjuvant therapy. Previous treatment with standard of care chemotherapy regimens in combination with molecular targeted therapies (e.g., VEGF and EGFR pathway inhibitors and immuno-oncology agents) is permitted. Previous treatment with maintenance therapy (e.g., capecitabine) is also allowed.
    5. Known RAS and BRAF status. Patients with wild-type KRAS tumours must have received prior treatment with an EGFR inhibitor, unless this was not standard of care according to relevant region-specific treatment recommendations.
    6. Known UGT1A1 status, or patient consents to UGT1A1 status testing if unknown.
    7. Age ≥18 years.
    8. Minimum life expectancy of ≥12 weeks.
    9. ECOG Performance status 0 or 1.
    10. Adequate bone marrow function as defined by: absolute neutrophil count (ANC) ≥1.5×10^9/L, platelet count ≥100×10^9/L, and haemoglobin ≥9 g/dL.
    11. Adequate liver function, as defined by: serum total bilirubin ≤1.5×upper limit of normal (ULN), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5×ULN (or ≤5×ULN if liver metastases are present).
    12. Adequate renal function assessed as serum creatinine <1.5×ULN or glomerular filtration rate ≥50 mL/min (calculated by the Cockcroft-Gault method).
    13. Serum albumin ≥3 g/dL.
    14. Ability to comply with protocol requirements.
    15. Female patients of child-bearing potential must have a negative pregnancy test within 7 days prior to the first study drug administration. This criterion does not apply to patients who have had a previous hysterectomy or bilateral oophorectomy. Male patients and female patients of child-bearing potential must agree to practice true abstinence or to use two highly effective forms of contraception, one of which must be a barrier method. These forms of contraception must be used from the time of signing consent, throughout the treatment period, and for 6 months following the last dose of any study medication. Oral or injectable contraceptive agents cannot be the sole method of contraception.
    16. Patients must have been advised to take measures to avoid or minimize exposure to UV light for the duration of study participation and for a period of 4 weeks following the last dose of study medication.
    1. Obtención del consentimiento informado por escrito.
    2. Confirmación histológica o citológica de adenocarcinoma colorrectal (excepto cánceres apendiculares y del canal anal, así como cánceres colorrectales de histología mixta [p.ej., adenocarcinoma mucinoso, carcinoma micropapilar, carcinoma de células en anillo de sello]) irresecable y/o metastásico.
    3. Enfermedad medible (según lo determinado por los criterios RECIST v1.1).
