For doctors
What is it and how is it used?
SUTENT is a medicine used to treat cancer by preventing the activity of a special group of proteins which are known to be involved in the growth and spread of cancer cells.
SUTENT will only be prescribed to you by a doctor with experienced in the use of anti-cancer medicinal products.
Gastrointestinal stromal tumour (GIST)
SUTENT is indicated for the treatment of unresectable and/or metastatic malignantgastrointestinal stromal tumour (GIST) in adults after failure of imatinib mesilate treatment due to resistance or intolerance. GIST is a cancer of the stomach and bowels, originating from uncontrolled cell growth of the supporting tissues of these organs. SUTENT inhibits the growth of these cells.
Metastatic renal cell carcinoma (MRCC)
SUTENT is indicated for the treatment of advanced metastatic renal cell carcinoma (MRCC) in adults. MRCC is a form of kidney cancer that involves cancerous changes in the cells of the renal tubule.
Pancreatic neuroendocrine tumours (pNET)
SUTENT is indicated for the treatment of unresectable or metastatic, well-differentiated pancreatic neuroendocrine tumours with disease progression in adults. pNET is a rare cancer originating in the hormone-secreting cells of the pancreas.
Experience with SUTENT as first-line treatment is limited.
If you have any questions about how SUTENT works or why this medicine has been prescribed for you, ask your doctor.

For doctors
What is it?
Sutent is a medicine that contains the active substance sunitinib. It is available as capsules (orange: 12.5 mg; caramel and orange: 25 mg; yellow: 37.5 mg; caramel: 50 mg).
What is it used for?
Sutent is used to treat adults with the following types of cancer:
The medicine can only be obtained with a prescription.
How is it used?
Treatment with Sutent should be started by doctors who have experience in administering anticancer medicines.
For GIST and metastatic renal cell carcinoma, Sutent is given in six-week cycles, at a dose of 50 mg once a day for four weeks, followed by a two-week ‘rest period’. The dose can be adjusted according to the patient’s response to the treatment, but should be kept within the range of 25 to 75 mg.
For pancreatic neuroendocrine tumours, Sutent is given at a dose of 37.5 mg once a day without a rest period. This dose may also be adjusted.
How does it work?
The active substance in Sutent, sunitinib, is a protein kinase inhibitor. This means that it blocks some specific enzymes known as protein kinases. These enzymes can be found in some receptors at the surface of cancer cells, where they are involved in the growth and spread of cancer cells and in the blood vessels that supply the tumours, where they are involved in the development of new blood vessels. By blocking these enzymes, Sutent can reduce the growth and spread of the cancer and cut off the blood supply that keeps cancer cells growing.
How has it been studied?
Sutent was compared with placebo (a dummy treatment) in 312 patients with GIST whose previous treatment with imatinib had failed and in 171 patients with worsening pancreatic neuroendocrine tumours that could not be removed with surgery.. Sutent was also compared with another anticancer medicine, interferon alfa, in 750 patients with metastatic renal cell carcinoma whose cancer had not been treated before.
The main measure of effectiveness in all of the studies was how long the patients lived without their tumours getting worse.
What benefits has it shown during the studies?
Sutent was more effective than placebo in treating GIST and pancreatic neuroendocrine tumours. Patients with GIST taking Sutent lived for an average of 27.3 weeks without the disease getting worse, compared with 6.4 weeks in the patients taking placebo. For pancreatic neuroendocrine tumours the figures were 11.4 months in the Sutent group and 5.5 months in the placebo group.
In metastatic renal cell carcinoma, patients taking Sutent lived for an average of 47.3 weeks without their disease worsening, compared with 22.0 weeks in the patients receiving interferon alfa.
What is the risk associated?
The most common side effects with Sutent (seen in more than 20% of patients) include fatigue (tiredness), gastrointestinal disorders (such as diarrhoea, feeling sick, inflammation of the lining of the mouth, indigestion and vomiting), skin discoloration, dysgeusia (taste disturbances) and loss of appetite. For the full list of all side effects reported with Sutent, see the package leaflet.
Sutent should not be used in people who may be hypersensitive (allergic) to sunitinib or any of the other ingredients.
Why has it been approved?
The CHMP decided that Sutent’s benefits are greater than its risks and recommended that it be given marketing authorisation.
Sutent was originally given ‘conditional approval’. This means that there was more evidence to come about the medicine, in particular in the treatment of renal cell carcinoma. As the company has supplied the additional information necessary, the authorisation has been switched from conditional to full approval.
Further information
The European Commission granted a conditional marketing authorisation valid throughout the European Union for Sutent to Pfizer Ltd on 19 July 2006. This was switched to a full marketing authorisation on 11 January 2007. The marketing authorisation is valid for five years, after which it can be renewed. europa.eu/Find medicine/Human medicines/European Public Assessment Reports. For more information about treatment with Sutent, read the package leaflet (also part of the EPAR) or contact your doctor or pharmacist.
