Sutent is a cancer medicine currently authorised for treating the following cancers:
Sutent has been authorised since July 2006 and contains the active substance sunitinib.
Sutent was expected to be used to delay or prevent the return of kidney cancer in patients who have had surgery and are at high risk of their cancer coming back.
The active substance in Sutent, sunitinib, is a protein kinase inhibitor. This means that it blocks specific enzymes known as protein kinases that are involved in the growth and spread of cancer cells and the development of new blood vessels supplying them. 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.
The company presented results of a main study comparing Sutent with placebo (a dummy treatment) in 615 patients at high risk of their kidney cancer coming back after surgery. Patients were treated for around a year and the study looked at how long it took for the cancer to come back (disease-free survival).
The evaluation had finished and the CHMP had given a negative opinion. The company had requested a re?examination of the negative opinion, but this re?examination had not yet finished when the company withdrew the application.
Based on the review of the data, at the time of the withdrawal, the CHMP had given a negative opinion, recommending that the marketing authorisation for Sutent not be changed to add the treatment of patients at high risk of kidney cancer returning after surgery.
The CHMP considered that the evidence that Sutent delays the return of the cancer was not convincing. When data from patients at highest risk of cancer returning were looked at separately, the benefits of Sutent were still not convincing. In addition, the medicine has known side effects that affect patients' quality of life.
Therefore, at the time of the withdrawal, the CHMP was of the opinion that the benefits of Sutent in the treatment of patients at high risk of kidney cancer returning after surgery did not outweigh its risks.
In its letter notifying the Agency of the withdrawal of application, the company stated that it was withdrawing because the data provided do not allow the CHMP to conclude that the benefit outweighs the risks.
The company informed the CHMP that there are no consequences for patients currently included in clinical trials using Sutent.
If you are in a clinical trial and need more information about your treatment, contact the doctor who is giving it to you.
There are no consequences for Sutent in its authorised uses.
