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 ).

    General information about the trial
    Main objective of the trial
    To evaluate if the maintenance therapy with AG-013736 is able to improve the PFS in patients with low risk of recurrence and advanced CRC without progressive disease after 6 months of treatment with an standard front line chemotherapy
    Protection of trial subjects
    Palliative treatment and supportive treatment for symptoms related to the disease, including pain treatments. Patients could receive loperamide and other treatments for diarrhea. Narcotic or anti-inflammatory analgesics could be used if needed. Antibiotics could be used if needed. Epoetin, darbepoetin and Colony Stimulating Factors could be used if needed. Transfusion of red blood cells or platelets could be used if needed. Low dose of oral steroids (short cycle) or topical or inhaled corticosteroids could be used if needed. Antihypertensive therapy (with amlodipine, bepridil, felodipine) if needed.
    Background therapy
    Colorectal cancer (CRC) is the third most common type of cancer worldwide and the fourth leading cause of death. The prognosis of patients with metastatic CRC has improved significantly due to the introduction of effective cytotoxic drugs in first-line therapy (irinotecan and oxaliplatin), which in turn don't present cross-resistance, in combination with targeted agents such as epidermal growth factor inhibitors and vascular endothelial growth factor inhibitors. The median survival of these patients is approximately 2 years, and they are usually treated until progression or unacceptable toxicity; consequently it is needed the evaluation of new treatment alternatives which allow to control tumor progression and minimize all accumulative adverse events, providing a good quality of life to the patients as long as possible.
    Evidence for comparator
    Axitinib (AG-013736) is an tyrosine kinase inhibitor that inhibits the proangiogenic cytokines VEGF and PDGF, exerting consequently an antiangiogenic effect. Phase 2 trials are have been completed or are ongoing in several kind of tumors: metastatic breast cancer non small cell lung cancer, renal cell carcinoma, thyroid cancer, malignant melanoma, advanced pancreatic cancer and colorectal cancer. One pivotal phase 3 study in renal cell carcinoma is currently active. The adverse events reported in clinical trials are considered manageable, usually reversible and expected for this kind of agents. The adverse events more commonly reported were: fatigue, diarrhea, hypertension, anorexia, nausea, dysphonia, Palmoplantar Erythrodysestesia Syndrome, weight loss, headache, cough, constipation, proteinuria and hypothiroidism. Grade 3 adverse events or superior more common occurred were hypertension and fatigue.
