Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
This trial compared 2 different orders (sequences) of having everolimus and sunitinib for kidney cancer that had spread to other parts of the body. It was for people who had the most common type of kidney cancer called renal cell cancer.
Doctors often use biological therapy to treat advanced kidney cancer. One of the drugs they may use is called sunitinib. But doctors are looking for new ways to treat people with kidney cancer.
In this trial they compared giving a drug called everolimus (also known as Afinitor) before sunitinib with giving everolimus after sunitinib. Everolimus is also a type of biological therapy. It stops a particular protein called from working properly. mTOR controls other proteins that trigger cancer cells to grow. By blocking mTOR, everolimus helps to stop cancer growing.
Some people had sunitinib to begin with and then if their cancer got worse, they stopped that and started everolimus. Some people started treatment with everolimus and then changed to sunitinib if their cancer got worse.
The aims of the study were to
The trial team found that giving everolimus before sunitinib didn’t work as well as giving sunitinib before everolimus to treat kidney cancer that had spread.
This was an international phase 2 trial. It was a randomised trial. The 471 people who took part were put into 1 of 2 treatment groups. Neither they nor their doctor could choose which group they were in.
When the researchers looked at the average length of time people lived without any sign of their cancer getting worse they found it was
When their cancer got worse, just under half of the people in each group followed on with their treatment and changed over to other drug.
The researchers then looked at the average overall length of time people lived, they found it was
The most common side effects of both everolimus and sunitinib as first treatments were
The trial team concluded that as a first treatment for kidney cancer that has spread everolimus was not as good as sunitinib. So having sunitinib first followed by everolimus when the cancer got worse should remain the ].
